Cognition-driven decision support system (DSS) has been recognized as a paradigm in the research and development of business intelligence (BI). Cognitive decision support aims to help managers in their decision making from human cognitive aspects, such as thinking, sensing, understanding and predicting, and fully reuse their experience. Among these cognitive aspects, decision makers situation awareness (SA) and mental models are considered to be two important prerequisites fordecision making , particularly in ill-structured and dynamic decision situations with uncertainties, time pressure and high personal stake. In todays business domain,decision making is becoming increasingly complex. To make a successful decision, managers SA about their business environments becomes a critical factor. This book presents theoretical models as well practical techniques of cognitiondriven DSS. It first introduces some important concepts of cognition orientation indecision making process and some techniques in related research areas including DSS, data warehouse and BI, offering readers a preliminary for moving forward in this book. It then proposes a cognition-driven decision process (CDDP) model which incorporates SA and experience (mental models) as its central components. The goal of the CDDP model is to facilitate cognitive decision support to managers on the basis of BI systems. It also presents relevant techniques developed to support the implementation of the CDDP model in a BI environment

It has become highly desirable to provide users with ?exible ways to query/search information over databases as simple as keyword search like Google search. This book surveys the recent developments on keyword search over databases, and focuses on ?nding structural information among objects in a database using a set of keywords. Such structural information to be returned can be either trees or subgraphs representing how the objects, that contain the required keywords, are interconnected in a relational database or in an XML database. The structural keyword search is completely different from ?nding documents that contain all the user-given keywords. The former focuses on the interconnected object structures, whereas the latter focuses on the object content. The book is organized as follows. In Chapter 1, we highlight the main research issues on the structural keyword search in different contexts. In Chapter 2, we focus on supporting structural keyword search in a relational database management system using the SQL query language. We concentrate on how to generate a set of SQL queries that can ?nd all the structural information among records in a relational database completely, and how to evaluate the generated set of SQL queries ef?ciently.In Chapter 3,we discuss graph algorithms for structural keyword search by treating an entire relational database as a large data graph. In Chapter 4, we discuss structural keyword search in a large tree-structured XML database.In Chapter 5,we highlight several interesting research issues regarding keyword search on databases. The book can be used as either an extended survey for people who are interested in the structural keyword search or a reference book for a postgraduate course on the related topics.

Actionable knowledge discovery is selected as one of the greatest challenges (Ankerst, 2002; Fayyad, Shapiro, & Uthurusamy, 2003) of next-generation knowledge discovery in database (KDD) studies (Han & Kamber, 2006). In the existing data mining, often mined patterns are nonactionable to real user needs. To enhance knowledge actionability, domain-related social intelligence is substantially essential (Cao et al., 2006b). The involvement of domain-related social intelligence into data mining leads to domaindriven data mining (Cao & Zhang, 2006a, 2007a), which complements traditional data-centered mining methodology. Domain-related social intelligence consists of intelligence of human, domain, environment, society and cyberspace, which complements data intelligence. The extension of KDD toward domain-driven data mining involves many challenging but promising research and development issues in KDD. Studies in regard to these issues may promote the paradigm shift of KDD from data-centered interesting pattern mining to domain-driven actionable knowledge discovery, and the deployment shift from simulated data set-based to real-life data and business environment-oriented as widely predicted.

In recent years, more and morc researchers have been involved in research on both agent technology and data mining. A clear disciplinary effort has been activa ted toward removing the boundary between them, that is the interaction and integrati on be tween agent technology and data mining. We refer this to agent mining as a new area. The marriage of agents and data mining is driven by challenges faced by both communities, and the need of developing more advanced intelligence, in formation processi ng and systems. This chapter presents an overall picture of agent mining from the perspective of positioning it as an emerging area. We summarize the main driving forces, compleme ntary essence, di sci plinary framework , applications, case studies, and trends and directions, as well as brief observation on agent-driven data mining, data mining-driven agents, and mutual issues in agent mini ng. Arguably, we draw the following conclusions: (I) agent mining emerges as a new area in the scientific fam il y, (2) both agent technology and data mining can greatly benefit from agent mining, (3) it is very promising to resu lL in additional advancement in intelligent information processing and systems. However, as a new open area, there are many issues waiting for research and development from theoretical, technological and practical perspectives.

This paper discusses a newly proposed Morphotronic System paradigm that can be used as a general computation model for construction of software. The Morphotronic System allows for a definition of very flexible software prototypes, in which a processing path can be interpreted as an extremum principle. This approach offers a significant improvement to traditional software practices. The system purpose is stated as a conceptual input to the computer system at a starting point of the computation process while the local machine state is completely ignored. The system context and its rules are generated as resources to allocate the computational components. The morphotronic system applies non-Euclidean geometry which allows to shape the context and to define the projection operators for an ideal network of forms.

Enterprise information systems have rapidly evolved over the last decade. We expect these changes to accelerate during this decade as a result of new trends in enterprise computing. We argue in this chapter that information and communication technology (ICT) remains strategically important to organizations in the 21st century despite the prevailing trend to outsource ICT and related business processes. We have identified a number of important trends that include the move towards the software as a service (SaaS) model for enterprise applications, increased commitment to process orientation, and emphasis on managing the relationship between business and ICT using services. These trends lead to more effective management of ICT and closer integration of ICT with entrepreneurial activities and business processes in organizations, resulting in improvements in return on investment. These trends will have dramatic impact on both the suppliers and users of ICT, and will necessitate the reevaluation of the approach to ICT education as both the composition and qualifications of ICT workforce will undergo a fundamental change.

Gene expression datasets used in biomedical data mining frequently have two characteristics: they have many thousand attributes but only relatively few sample points and the measurements are noisy. In other words, individual expression measurements may be untrustworthy. Gene Feature Ranking (GFR) is a feature selection methodology that addresses these domain specific characteristics by selecting features (i.e. genes) based on two criteria: (i) how well the gene can discriminate between classes of patient and (ii) the trustworthiness of the microarray data associated with the gene. An example from the pediatric cancer domain demonstrates the use of GFR and compares its performance with a feature selection method that does not explicitly address the trustworthiness of the underlying data. © 2009 Springer US.

The main problem of osteolysis and loosening of prosthetic components in current polyethylene hip joints is briefly discussed, and alternative bearings, such as metal-on-metal, are introduced. A brief account of the historical development of metal-on-metal hip joint replacements is presented. An overview is given to tribology and its scope, as well as associated techniques. Detailed discussion of results and important findings for metal-onmetal hip implants are presented for contact mechanics, friction, lubrication, and wear. The importance of integrated studies of friction, wear, and lubrication is demonstrated in order to understand the complex tribology mechanism in metal-on-metal hip implants. Concerns about the long-term potential adverse biological reactions due to metallic ions and debris are discussed, and the importance of coupled tribological-biological studies of metal-on-metal hip implants is emphasized. Finally, future developments of both tribological techniques and new hip joint implants are summarized.

This chapter clearly shows that there are many published methods suitable for separating and characterizing ultra-high molecular weight polyethylene (UHMWPE) wear particles from tissues and simulator lubricants. Initial attempts to characterize UHMWPE wear particles released into the periprosthetic tissues around failing implants used histological staining and polarized light microscopy to identify UHMWPE. Many of these methods successfully remove proteins and lipids from particles, preserve particle morphology, and yield similar particle size distributions. Clearly, advances in technology are continually being employed and the limitations of each method are now widely recognized. Particle characterization, in terms of size and volume distributions and particle contribution to the osteolytic potential of new and existing UHMWPE materials, is recognized by academic and industrial stakeholders as being an important step in the preclinical assessment of total joint replacements. However, there is no one standard method for isolation or characterization of UHMWPE particles that can be applied to both tissues and simulator lubricant samples, and this would clearly be advantageous. © 2009 Copyright © 2009 Elsevier Inc.

The mainstream data mining faces critical challenges and lacks of soft power in solving real-world complex problems when deployed. Following the paradigm shift from 'data mining' to 'knowledge discovery', we believe much more thorough efforts are essential for promoting the wide acceptance and employment of knowledge discovery in real-world smart decision making. To this end, we expect a new paradigm shift from 'data-centered knowledge discovery' to 'domain-driven actionable knowledge discovery'. In the domain-driven actionable knowledge discovery, ubiquitous intelligence must be involved and meta-synthesized into the mining process, and an actionable knowledge discovery-based problem-solving system is formed as the space for data mining. This is the motivation and aim of developing Domain Driven Data Mining (D 3 M for short). This chapter briefs the main reasons, ideas and open issues in D 3 M. © 2009 Springer US.

Decision-making processes in relation to complex natural resources require recognition and accommodation of diverse and competing perspectives in a decision context that is frequently ill defined and fraught with value judgements. Online environments can be used to develop students’ skills and understanding of these issues. The focus of this chapter is the learning design of an online roleplay-simulation (Mekong e-Sim) which was created to develop learning experiences about these types of issues across multiple institutions with students from the disciplines of engineering and the humanities. The key stages of interaction within the e-Sim are described and linked to student tasks, resources, and supports. The evolution and adaptation of the learning design used in the Mekong e-Sim has been described. Eight key challenges in the design and implementation of online roleplay-simulations have been identified. In this chapter, we have tried to address a gap in the online role-based collaborative learning literature about the design of these activities, linkages between pedagogy and information and communication technology, and how to exploit these linkages for effective learning.

The Morphotronic approach postulates a significant improvement to traditional system design thinking based on the Turing Machine model. The paper presents a range of important concepts and definitions supporting this proposition.The Morphotronic system represents an abstract universe of the objects. This universe of objects has two interpretations as in the case of the voltages and currents in the electrical circuit. For the space of the voltages the objects are the voltages at edges of the electrical circuit. For the current space of the currents the objects are the currents in any edge. The dimension of the object space is equal to the number of edges in the electrical circuit. Such a space allows dual interpretation of the current and voltages. Other possible dual variables can be used in the morphotronic system as forces and the fluxes in mechanics or dissipative thermodynamics, in a general way the dual interpretation of the object space will be denoted as causes and effects. The morphogenetic system can be modelled by samples of the causes and effects. The morphotronic system with the samples generates the algorithm to implement the purpose in the system. Providing that the samples of the effect and the purpose denote a virtual cause, the vector E can be computed so that it represents the effective origin of the causes inside the purpose map. With the cause-effect rule the effective causes can be computed obtaining results that are coherent with the samples. Providing that the virtual cause is given by purpose the effective causes can be generated in agreement with the samples. The described algorithm is denoted as the projection operator that transforms a virtual cause (purpose) into an effective cause.

This chapter begins by describing a universally recurring socio-cultural game of inter-group competition for control of resources. It next describes efforts to author software agents able to play the game as real humans would - which suggests the ability to study alternative ways to influence them, observe PMESII effects, and potentially understand how best to alter the outcomes of potential conflict situations. These agents are unscripted, but use their decision making to react to events as they unfold and to plan out responses. For each agent, a software called PMFserv operates its perception and runs its physiology and personality/value system to determine fatigue and hunger, injuries and related stressors, grievances, tension buildup, impact of rumors and speech acts, emotions, and various collective and individual action decisions. The chapter wraps up with a correspondence test from a SE Asian ethnic conflict, the results of which indicate significant correlation between real and agentbased outcomes. © 2009 Springer-Verlag Berlin Heidelberg.

Wireless Sensor Networks (WSN) is fast becoming the holy grail of digital surveillance, data monitoring and analysis. Being relatively cheap, low-powered and easy to deploy WSNs is being adopted in a range of different fields. Currently, the focus is towards optimizing techniques used to form sensor clusters and to route data within a network. In order to satisfy these goals a significant amount of research is being done globally and what tends to be lacking at times is the right tools to make such research work less time consuming and inexpensive. The use of simulation tools is one such adaptation that can help researchers closely analyse a particular aspect of WSN while sticking with a known environment that is applicable to other scenarios in a similar way. This paper presents the performance and features of WSNSim, a WSN Simulator and the immediate advantages that can be experienced by researchers working on various realms in this area.

The Force Field (F 2) method is a novel approach for multi-robot motion planning and coordination. The setting of parameters in the (F 2) method, noticeably, can affect its performance. In this research, we present the Ranked Pareto Particle Swarm Optimization (RPPSO) approach as an extension of the basic idea of Particle Swarm Optimization (PSO), which makes it capable of solving multiobjective optimization problems efficiently. In the RPPSO, particles are initiated randomly in the search space; these particles are then evaluated for their qualities with regard to all objectives. Those particles with highly-ranked qualities have preferences to enter the set of Global Best vectors, which stores many currently best solutions found by particles. Thus, particles in RPPSO will search towards many possible directions and the diversity among solutions is well preserved. Ideally, a set of optimal solutions will be found when the termination criterion is met. The effectiveness of the proposed RPPSO is verified in simulation studies. Satisfactory results are obtained for multiobjective optimization problems of multi-robot motion planning in challenging environments with obstacles. © 2009 Springer-Verlag Berlin Heidelberg.

Spiral Architecture is a relatively new and powerful approach to image processing. It contains very useful geometric and algebraic properties. Based on the abundant research achievements in the past decades, it is shown that Spiral Architecture will play an increasingly important role in image processing and computer vision. This chapter presents a significant application of Spiral Architecture for distributed image processing. It demonstrates the impressive characteristics of spiral architecture for high performance image processing. The proposed method tackles several challenging practical problems during the implementation. The proposed method reduces the data communication between the processing nodes and is configurable. Moreover, the proposed partitioning scheme has a consistent approach: after image partitioning each sub-image should be a representative of the original one without changing the basic object, which is important to the related image processing operations. © 2010, IGI Global.

Debt detection is important for improving payment accuracy in social security. Since debt detection from customer transaction data can be generally modelled as a fraud detection problem, a straightforward solution is to extract features from transaction sequences and build a sequence classifier for debts. For long-running debt detections, the patterns in the transaction sequences may exhibit variation from time to time, which makes it imperative to adapt classification to the pattern variation. In this paper, we present a novel adaptive sequence classification framework for debt detection in a social security application. The central technique is to catch up with the pattern variation by boosting discriminative patterns and depressing less discriminative ones according to the latest sequence data. © 2009 Springer-Verlag Berlin Heidelberg.

Spiral Architecture, a hexagonal image structure is a novel and powerful approach to machine vision system. The pixels on Spiral architecture are geometrically arranged using a 1D (Spiral) addressing scheme in an ascending order along a spiral-like curve. Spiral addition and Spiral multiplication are defined based on the Spiral addresses on Spiral Architecture. These two fundamental operations result in fast and easy translation, rotation and separation on images, and hence play very important roles for image processing on Spiral Architecture. Moreover, 2D coordinates according to rows and columns defined on Spiral Structure provide a good mapping to the ordinary 2D coordinates defined on the common square image structure. Therefore, how to convert the 1D Spiral addresses from and to the 2D coordinates on Spiral Architecture has become very important to apply the theory developed on a hexagonal image structure for image processing (e.g., rotation). In this paper, we perform a fast way to correctly locate any hexagonal pixel when its Spiral address is known, and compute the Spiral address of any hexagonal pixel when its location is known. As an illustration of the use of conversions, we demonstrate the accurate image translation and rotation using experimental results.

This chapter presents a systematic exposition of predicate transformer semantics for quantum programs. It is divided into two parts: The first part reviews the state transformer (forward) semantics of quantum programs according to Selingerâs suggestion of representing quantum programs by superoperators and elucidates DâHondt-Panangadenâs theory of quantum weakest preconditions in detail. In the second part, we develop a quite complete predicate transformer semantics of quantum programs based on Birkhoffâvon Neumann quantum logic by considering only quantum predicates expressed by projection operators. In particular, the universal coujunctivity and termination law of quantum programs are proved, and Hoareâs induction rule is established in the quantum setting.

This chapter presents four applications of data mining in social security. The first is an application of decision tree and association rules to find the demographic patterns of customers. Sequence mining is used in the second application to find activity sequence patterns related to debt occurrence. In the third application, combined association rules are mined from heterogeneous data sources to discover patterns of slow payers and quick payers. In the last application, clustering and analysis of variance are employed to check the effectiveness of a new policy.

Several countries around the globe are moving towards national and international standards for Electronic Health Records (EHRs). One function of the standards is to guide the long-term convergence of local systems into integrated evolving national health information systems. The Australian commonwealth government is implementing a nationwide EHR system whereby every Australian will be able to upload data to his or her EHR. Thus Australians, if they wish, will eventually be able to upload data from on-body sensors and in-home monitoring systems to their EHRs. This article explores issues associated with the architecture of systems which allow medical records to be updated with information from monitoring/sensor systems. A prototype was developed to determine some of the key architectural considerations. A sensor simulator was implemented for testing purposes which allows a user of the simulator to impersonate a bed or group of in-home or on-body sensors connected with a person who is in a hospital, retirement home or private home. Findings are discussed relating to key architectural considerations including security, maintainability and modularity.

By assuming the metallic double-walled carbon nanotubes as two coaxial free electron gas layers with linearized hydrodynamic model, it is shown that surface plasmons coupled with electromagnetic fields can be excited on a metallic double-walled carbon nanotube and propagate along its axis. Dispersion relations of surface plasmons for E-type and B-type waves in various inner-outer radii and various interlayer distances for long metallic double-walled carbon nanotubes are obtained.

This article proposes a novel approach for the prediction of maximum dry density (MDD) and optimum moisture content (OMC) of soil-stabiliser mix by using radial basis function (RBF) neural networks. RBF neural network is utilised to construct comprehensive and accurate models to be able to relate the MDD and OMC of stabilised soil to the properties of natural soil such as particle size distribution, plasticity, linear shrinkage and the type and quantity of stabilising additives. Two separate sets of RBF prediction models, one for the MDD and the other for the OMC, have been developed. A parametric study was also conducted in this study using the results obtained from the proposed models to evaluate the sensitivity of MDD and OMC due to variation of the influencing parameters. A comprehensive set of data including a wide range of soil types obtained from previously published stabilisation test results was used for training, validation and testing the prediction models. The accuracy of the proposed models is satisfactory when compared with that of the experimental results. The results of proposed RBF models were further compared with those of the existing models found in literature and found to be more accurate. © 2009 Taylor & Francis Group, LLC.

Rainwater has been used as drinking water in Thailand for centuries especially in the rural parts and is accepted as an important water resource. From past to present, the quality of rainwater has changed with the landuse of the landscape, and its water quality is influenced by a diverse range of conditions such as the management of pollutant sources, the catchment condition, wind and meteorological conditions, and the location of rainwater collection points. In this study, the quality of rainwater collected off roofs at several locations was examined. Granular activated carbon (GAC) filtration was used as a pretreatment to microfiltration (MF) to remove the dissolved organic matter (DOC). After an initial adsorption period, the biofilm that formed on the GAC (biofilter) was found to remove DOC by up to 40%, 35%, and 15% for bed filter depths of 15, 10, and 5 cm, respectively. Biofilters also removed nitrate and phosphate by more than 80% and 35%. The hollow fiber membrane microfiltration with pore size of 0.1 μm was used to treat the effluent from biofiltration to remove the microorganisms/pathogens in the rainwater. Although there was no significant additional removal of DOC by MF, the biofilter removed all microorganisms. The use of biofilters as pretreatment to MF/UF could remove a higher amount of DOC, remove microorganisms, increase the membrane treatment efficiency, and reduce membrane fouling.

Abstract Background MicroRNAs (MiRNAs) are short non-coding RNAs that control protein expression through various mechanisms. Their altered expression has been shown to be associated with various cancers. The aim of this study was to profile miRNA expression in colorectal cancer (CRC) and to analyze the function of specific miRNAs in CRC cells. MirVana miRNA Bioarrays were used to determine the miRNA expression profile in eight CRC cell line models, 45 human CRC samples of different stages, and four matched normal colon tissue samples. SW620 CRC cells were stably transduced with miR-143 or miR-145 expression vectors and analyzed in vitro for cell proliferation, cell differentiation and anchorage-independent growth. Signalling pathways associated with differentially expressed miRNAs were identified using a gene set enrichment analysis. Results The expression analysis of clinical CRC samples identified 37 miRNAs that were differentially expressed between CRC and normal tissue. Furthermore, several of these miRNAs were associated with CRC tumor progression including loss of miR-133a and gain of miR-224. We identified 11 common miRNAs that were differentially expressed between normal colon and CRC in both the cell line models and clinical samples. In vitro functional studies indicated that miR-143 and miR-145 appear to function in opposing manners to either inhibit or augment cell proliferation in a metastatic CRC model. The pathways targeted by miR-143 and miR-145 showed no significant overlap. Furthermore, gene expression analysis of metastatic versus non-metastatic isogenic cell lines indicated that miR-145 targets involved in cell cycle and neuregulin pathways were significantly down-regulated in the metastatic context. ...

Experiments were conducted in a laboratory scale membrane bio-reactor (MBR) system equipped with a side stream flat sheet membrane. Six runs lasting different durations (2, 4, 6, 9, 15 and 20 days) were conducted at an aeration rate of 2 m3 h-1 m-2 to understand the temporal variation of chemistry of foulant that attached on the membrane surface. The foulant attached on the membrane surface was extracted with 0.5% (v/v) NaOH solution and the extract was analysed using fluorescent spectroscopy and size exclusion chromatography. Variation of low- and high-molecular weight substances with evolution of time was compared. The results showed that the nature of foulant changed with the evolution of time. Four runs conducted for a short duration (2, 4, 6 and 9 days), low-molecular weight substances were dominant in the foulant whereas for long duration runs (15 and 20 days), high-molecular weight substances were mainly observed. Moreover, the foulant close to the membrane surface contained mainly protein and soluble microbial by-products.

Many studies have been performed to analyse the influence of compounds present in different fractions of the membrane foulants. The aim of this study was to reveal the changing chemistry of compounds present in membrane foulant with the evolution of time. Membrane fouling in a side stream membrane bioreactor (MBR) reactor was investigated. Constant flux filtration was employed in an MBR operation. Air bubbles were injected at 2 m3 h1 m2 for six different durations (2, 4, 6, 9, 15 and 20 days) of MBR operation. The foulant on the membrane surface was extracted using NaOH solution (5%) and analysed using fluorescent spectroscopy. The spectra showed the changing chemistry of foulant with the evolution of time. It showed low molecular weight substances such as amino acids and small aromatic proteins were dominant in the foulant at the beginning of the experiment but its concentration decreased with time. On the other hand BOD5 type substances concentration increased with time from the beginning of the experiment up to 9 days and there after decreased. The concentration of larger molecular weight soluble microbial by-products increased with evolution of time. Air bubbles at two aeration rate of 1m3 h1m2 and 2 m3 h1 m2 were also injected from the bottom of the membrane tanks to produce shear stresses on the membrane surface during 5 days of MBR operation to compare the effect of aeration in fouling propensity.

Phosphorus (P) deficiency is a major constraint for crop production in many parts of the world including Myanmar and field research into management of P fertilizers and P responsiveness of crops on infertile soils has been limited. The purpose of this study is to determine maize yield response to different forms of P fertilizers on an acidic (pH 4.9) P deficient (Olsen-P 8 mg kg -1) Yellow Earth (Acrisol) in Southern Shan State, Myanmar and to establish relationships between soil Olsen-P test values (0.5 M sodium bicarbonate extracted P) and maize yield. Field experiments were conducted during two cropping seasons. There were 15 treatments in total: P was applied at seven rates of a soluble P fertilizer as Triple superphosphate (TSP) (0-120 kg P ha-1) to establish a P response curve; one rate of a partially soluble P fertilizer (Chinese partially acidulated phosphate rock, CPAPR) and two organic P fertilizers (farmyard manure (FYM) and Tithonia diversifolia) at 20 kg P ha-1; combination of TSP and CPAPR at 20 kg P ha-1 with FYM and Tithonia at 20 kg P ha-1; an additional treatment (TSP 20 kg P ha-1 plus 2.5 t ha-1 dolomite) for assessing the liming effect of a local dolomite. In Year 1, applications of TSP at 40-60 kg P ha-1 produced near maximum grain yields, whereas in Year 2 this could be achieved with a reapplication of 20-30 kg P ha-1 on top of the residual value of the Year 1 application. In both years, CPAPR, TSP and Tithonia at 20 kg P ha-1 significantly increased maize grain yield, but FYM failed to increase grain yield. In Year 1, CPAPR and TSP effects on grain yield were higher than that of Tithonia but in Year 2 the effects were same for all these three treatments. In both years the combination of FYM (20 kg P ha -1) with TSP (20 kg P ha-1) produced significantly higher grain yield than TSP at 20 kg P ha-1 whereas 40 kg P ha-1 of TSP application did not significantly increase grain yield over the TSP application at 20 kg P ha-1. Similar results were o...

This study presents an integrated algorithm for forecasting oil production based on a Genetic Algorithm (GA) with variable parameters using stochastic procedures, time series and Analysis of Variance (ANOVA). The significance of the proposed algorithm is two fold. First, it is flexible and identifies the best model based on the results of ANOVA and MAPE, whereas previous studies consider the best fitted GA model based on Minimum Absolute Percentage Error (MAPE) or relative error results. Second, the proposed algorithm may identify conventional time series as the best model for future oil production forecasting because of its dynamic structure, whereas previous studies assume that GA always provides the best solutions and estimation. To show the applicability and superiority of the proposed algorithm, the data for oil production in USA, Russia, India and Brazil from 2001 to 2006 are used and applied to the proposed algorithm.

This study presents an integrated Artificial Neural Network (ANN) and time series framework to estimate and predict Signal to Interference Ratio (SIR) in Direct Sequence Code Division Multiple Access (DS/CDMA) systems. It is difficult to model uncertain behavior of SIR with only conventional ANN or time series and the integrated algorithm could be an ideal substitute for such cases. Artificial Neural Network (ANN) approach based on supervised multi layer perceptron (MLP) network are used in the proposed algorithm. All type of ANN-MLP are examined in present study. At last, Coefficient of Determination (R2) is used for selecting preferred model from different constructed MLP-ANN. One of unique feature of the proposed algorithm is utilization of Autocorrelation Function (ACF) to define input variables whereas conventional methods which use trial and error method. This is the first study that integrates ANN and time series for improved estimation of SIR in mobile CDMA systems. © 2009, INSInet Publication.

AbstractThere is considerable interest in characterization of wear debris from polyethylene (UHMWPE) bearing components used in total joint replacement. To isolate UHMWPE wear debris, tissue samples must be excised from regions adjacent to revised UHMWPE implant components, followed by exposure to one of many available tissue digestion methods. Numerous studies demonstrate successful digestion, but the relative efficiency of each method is not clear. The purpose of this study was to evaluate a variety of conditions for tissue digestion to provide a quantitative comparison of methods. Porcine and human hip tissues were exposed for 24 h to basic, acidic or enzymatic agents, filtered and digestion efficiency calculated based on the percentage of initial to final tissue weight. Of the conditions tested, 5 M NaOH, 5 M KOH, 15 M KOH or 15.8 M HNO3 yielded the most complete porcine hip tissue digestion (<1% residual tissue weight; p < 0.05). Proteinase K and Liberase Blendzyme 3 did not effectively digest tissue in a 24 h period. Similar to results from the porcine dataset, human tissues digestion was most efficient using 5 M NaOH, 5 M KOH or 15.8 M HNO3 (<1% residual tissue weight; p < 0.05). To verify that particle surface modifications did not occur after prolonged reagent exposure, GUR415 and Ceridust 3715 particles were immersed in each solution for 24 h. Overall, this study provides a framework for thorough and efficient digestive methods for UHMWPE wear debris extraction. © 2009 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2009

Whole-genome microRNA and gene expression analyses were used to monitor changes during retinoic acid induced differentiation of neuroblasts in vitro. Interestingly, the entire miR-17 family was over-represented among the down-regulated miRNA. The implications of these changes are considerable, as target gene prediction suggests that the miR-17 family is involved in the regulation of the mitogen-activated protein kinase (MAPK) signaling pathway, synaptic plasticity and other markers of neuronal differentiation. Significantly, many of the target responses predicted by changes in miRNA expression were supported by the observed changes in gene expression. As expected, markers of neuronal differentiation such as anti-apoptotic protein B-cell lymphoma 2 (BCL2), myocyte enhancer factor-2D (MEF2D) and zipper protein kinase (MAP3K12; aka ZPK/MUK/DLK) were each up-regulated in response to differentiation. The expression of these genes was also reduced in response to miR-17 and miR-20a transfection, and more specifically they were also shown to contain functional miRNA recognition elements for members of the miR-17 family by reporter gene assay. This suggests that the miR-17 family have an integral role in fine-tuning the pathways involved in the regulation of neuronal differentiation

AbstractIn some areas of software engineering research, there are several metamodels claiming to capture the main issues. Though it is profitable to have variety at the beginning of a research field, after some time, the diversity of metamodels becomes an obstacle, for instance to the sharing of results between research groups. To reach consensus and unification of existing metamodels, metamodel-driven software language engineering can be applied. This paper illustrates an application of software language engineering in the agent-oriented software engineering research domain. Here, we introduce a relatively generic agent-oriented metamodel whose suitability for supporting modeling language development is demonstrated by evaluating it with respect to several existing methodology-specific metamodels. First, the metamodel is constructed by a combination of bottom-up and top-down analysis and best practice. The concepts thus obtained and their relationships are then evaluated by mapping to two agent-oriented metamodels: TAO and Islander. We then refine the metamodel by extending the comparisons with the metamodels implicit or explicit within five more extant agent-oriented approaches: Adelfe, PASSI, Gaia, INGENIAS, and Tropos. The resultant FAML metamodel is a potential candidate for future standardization as an important component for engineering an agent modeling language.

This paper adopts a model-based security (MBS) approach to identify security requirements during the early stages of multi-agent system development. Our adopted MBS approach is underpinned by a metamodel independent of any specific methodology. It allows for security considerations to be embedded within any situated agent methodology which then prescribes security considerations within its work products. Using a standard model-driven engineering (MDE) approach, these work products are initially constructed as high abstraction models and then transformed into more precise models until code-specific models can be produced. A multi-agent system case study is used to illustrate the applicability of the proposed security-aware metamodel.

BACKGROUND & AIMS: Current methods of preoperative staging and predicting outcome following pancreatectomy for pancreatic cancer (PC) are inadequate. We evaluated the utility of multiple biomarkers from distinct biologic pathways as potential predictive markers of response to pancreatectomy and patient survival. METHODS: We assessed the relationship of candidate biomarkers known, or suspected, to be aberrantly expressed in PC, with disease-specific survival and response to therapy in a cohort of 601 patients. RESULTS: Of the 17 candidate biomarkers examined, only elevated expression of S100A2 was an independent predictor of survival in both the training (n = 162) and validation sets (n = 439; hazard ratio [HR], 2.19; 95% confidence interval [CI]: 1.48-3.25; P < .0001) when assessed in a multivariate model with clinical variables. Patients with high S100A2 expressing tumors had no survival benefit with pancreatectomy compared with those with locally advanced disease, whereas those without high S100A2 expression had a survival advantage of 10.6 months (19.4 vs 8.8 months, respectively) and a HR of 3.23 (95% Cl: 2.39-4.33; P < .0001). Of significance, patients with S100A2-negative tumors had a significant survival benefit from pancreatectomy even in the presence of involved surgical margins (median, 15.7 months; P = .0007) or lymph node metastases (median, 17.4 months; P = .0002). CONCLUSIONS: S100A2 expression is a good predictor of response to pancreatectomy for PC anti suggests that high S100A2 expression may be a marker of a metastatic phenotype. Prospective measurement of S100A2 expression in diagnostic biopsy samples has potential clinical Utility as a predictive marker of response to pancreatectomy and other therapies that target locoregional disease.

View description>>

This paper deals with detection of oil spill areas from Radarsat images for the Tanjung Piai coast of Strait of Malacca and subsequently model those spilled areas to generate coastal sensitivity index maps for the study area. Spill areas were classified based on their chemical composition and were extracted from satellite images supported with field surveys. Maps of the topography, land cover were constructed from the spatial data sets in GIS. Bathymetry map, shoreline sensitivity, socioeconomic, biological, wind and sea current data were extracted from various resources and modeled in GIS for oil spill trajectory simulation analysis. An oil spill simulation model was developed as a way to find the suitable solution for emergency response and management in case of any future spill occurs in the study area. Remote sensing, GIS and other geomatic systems can be employed to mitigate the ageold problems of information availability and timeliness, data management and synoptic inventory of natural resources when an oil spill caused by accident or human error. This paper describes application of remote sensing and GIS for detecting, mapping, evaluating and modeling of spills in sea environments in order to reduce responding time and qualify the decision making process in contingency planning.

Abstract. 1. Protein is important for a foraging animal to consume, as it promotes growth and enhances survival, particularly in web‐building spiders, which need to invest considerable protein into web building and may trade‐off growth for web investment.2. The influence of dietary protein uptake on growth and web investment was tested in the orb web spider Argiope keyserlingi, by feeding them flies reared on three different media: (1) high protein, (2) low protein, and (3) standard (control) media. There was a negative correlation between protein and energy content of the flies across treatments; flies reared on the high protein media had the highest protein, but lowest energy, while flies reared on the low protein media had the lowest protein but highest energy.3. It was found that silk investment and web architecture in A. keyserlingi was not affected by diet. Growth and decoration building were both enhanced when spiders were fed a high protein diet.4. It was concluded that protein intake, rather than energy, influenced both growth and decoration building because: (1) protein intake enhances growth in other animals, (2) protein is essential for silk synthesis, especially aciniform silk, and (3) protein is a limiting factor actively sought by foraging animals in natural environments.

We show the following: a randomly chosen pure state as a resource for measurement-based quantum computation iswith overwhelming probabilityof no greater help to a polynomially bounded classical control computer, than a string of random bits. Thus, unlike the familiar ``cluster states, the computing power of a classical control device is not increased from P to BQP (bounded-error, quantum polynomial time), but only to BPP (bounded-error, probabilistic polynomial time). The same holds if the task is to sample from a distribution rather than to perform a bounded-error computation. Furthermore, we show that our results can be extended to states with significantly less entanglement than random states.

Production Levelling is a method to balance production- and logistics capacities, avoid waste and thereby increase the efficiency in production. In high volume production levelling is successfully implemented, but needs to be modified in order to adapt it to low volume and high mix production.

The principle of production leveling is, expanding from the automotive industries, aimed to be implemented in the low volume high mix production. The creation of an even and repetitive production pattern by levelling is seen as main factor for smoothing the supply chain and as precondition for the realization of a low-inventory production. This can be realized only adapted due to inhomogeneous product-ranges and alternating customer-demands. In this article fundaments and possible stepups for production levelling in the low volume high mix production are shown. © GITO-Verlag.

PurposeThis paper provides insights into the evolution of the strategic alliance between Shell and Transfield Services in Sydney, Australia in the area of engineering and facilities management.Design/methodology/approachTo gain an in‐depth understanding of the distinct developmental phases in the alliance relationship, we conducted 12 interviews and a survey yielding 39 responses from the management and operations staff of both these organizations.FindingsInitially the alliance between Shell and Transfield Services was established with fundamental building blocks of trust and flexibility. However, as the relationship progressed with subsequent contract renewals, complex value adding demands were placed on the alliance. This paper provides insights into understanding three generations of evolution in the relationship‐starting from the building of a successful relationship based on labor savings and then on to one which seeks incremental innovations to become one of the most efficient maintenance operators in the world and finally seeking additional capabilities to continue improving alliance outcomes.Originality/valueThe paper is aimed at managers who are involved in structuring and managing outsourcing arrangements. Referring to outsourcing as an alliance arrangement, the paper points out that as alliance relationships mature, managers need to progress from a fee‐for‐service model to trusted collaboration, and finally to an alliance with joint strategic objectives. Drawing from the case of Shell and Transfield, we pre...

Trading agents are useful for developing and back-testing quality trading strategies to support smart trading actions in the market. However, most of the existing trading agent research oversimplifies trading strategies, and focuses on simulated ones. As a result, there exists a big gap between the deliverables and business needs when the developed strategies are deployed into the real life. Therefore, the actionable capability of developed trading agents is often very limited. This paper for the first time introduces effective approaches for optimizing and integrating multiple classes of strategies through trading agent collaboration. An integration and optimization approach is proposed to identify optimal trading strategy in each category, and further integrate optimal strategies crossing classes. Positions associated with these optimal strategies are recommended for trading agents to take actions in the market. Extensive experiments on a large quantity of real-life market data show that trading agents following the recommended strategies have great potential to obtain high benefits while low costs. This verifies that it is promising to develop trading agents toward workable and satisfying business needs. © Springer-Verlag London Limited 2008.

Behavior is increasingly recognized as a key entity in business intelligence and problem-solving. Even though behavior analysis has been extensively investigated in social sciences and behavior sciences, in which qualitative and psychological methods have been the main means, nevertheless to conduct formal representation and deep quantitative analysis it is timely to investigate behavior from the informatics perspective. This article highlights the basic framework of behavior informatics, which aims to supply methodologies, approaches, means and tools for formal behavior modeling and representation, behavioral data construction, behavior impact modeling, behavior network analysis, behavior pattern analysis, behavior presentation, management and use. Behavior informatics can greatly complement existing studies in terms of providing more formal, quantitative and computable mechanisms and tools for deep understanding and use.

The studies of complex systems have been recognized as one of the greatest challenges for current and future science and technology. Open complex giant systems (OCGSs) are a family of specially complex systems with system complexities such as openness, human involvement, societal characteristic, and intelligence emergence. They greatly challenge multiple disciplines such as system sciences, system engineering, cognitive sciences, information systems, artificial intelligence, and computer sciences. As a result, traditional problem-solving methodologies can help deal with them but are far from a mature solution methodology. The theory of qualitative-to-quantitative metasynthesis has been proposed as a breakthrough and effective methodology for the understanding and problem solving of OCGSs. In this paper, we propose the concepts of M-Interaction, M-Space, and M-Computing which are three key components for studying OCGS and building problem-solving systems. M-Interaction forms the main problem-solving mechanism of qualitative-to-quantitative metasynthesis; M-Space is the OCGS problem-solving system embedded with M-Interactions, while M-Computing consists of engineering approaches to the analysis, design, and implementation of M-Space and M-Interaction. We discuss the theoretical framework, problem-solving process, social cognitive evolution, intelligence emergence, and pitfalls of certain types of cognitions in developing M-Space and M-Interaction from the perspectives of cognitive sciences and social cognitive interaction. These can help one understand complex systems and develop effective problem-solving methodologies. © 2009 IEEE.

Autonomous agents and multiagent systems (or agents) and data mining and knowledge discovery (or data mining) are two of the most active areas in information technology. Ongoing research has revealed a number of intrinsic challenges and problems facing each area, which can't be addressed solely within the confines of the respective discipline. A profound insight of bringing these two communities together has unveiled a tremendous potential for new opportunities and wider applications through the synergy of agents and data mining. With increasing interest in this synergy, agent mining is emerging as a new research field studying the interaction and integration of agents and data mining. In this paper, we give an overall perspective of the driving forces, theoretical underpinnings, main research issues, and application domains of this field, while addressing the state-of-the-art of agent mining research and development. Our review is divided into three key research topics: agent-driven data mining, data mining-driven agents, and joint issues in the synergy of agents and data mining. This new and promising field exhibits a great potential for groundbreaking work from foundational, technological and practical perspectives.

Background: The prompt recognition and management of septic patients remains a challenge within the busy Emergency Department (ED). Prognostic screening aids have traditionally required time-delayed laboratory measurements not validated upon the emergency medicine population. Recently, a brief prognostic tool has been derived and subsequently validated in heterogeneous ED populations. Clinical Question: Can a risk-stratification tool predict 1-month mortality in ED patients with suspected infection? Evidence Review: Six studies evaluating the Mortality in the Emergency Department Sepsis (MEDS) score were identified and evaluated. Results: Higher MEDS scores are associated with increasing mortality. MEDS score's short- and long-term prognostic accuracy is superior to other sepsis scales as well as isolated biomarkers C-reactive protein and procalcitonin. MEDS' prognostic accuracy in severe sepsis is inferior to undifferentiated systemic inflammatory response syndrome (SIRS) patients. Conclusion: The MEDS score is an accurate and reliable prognostic tool for 28-day mortality in ED SIRS patients, but may not be optimal for those with severe sepsis. © 2009 Elsevier Inc.

This paper presents a new statistics-based evolutionary algorithm to improve the qualities of power supplies, in which operational costs and the stability of the power supply are optimised to provide a highly smooth but low-cost power supply service to customers. The proposed method is incorporated with the characteristics of the stochastic method, evolutionary algorithm and a more systematical statistical method, orthogonal design. It intends to compensate for the built-in randomness of the stochastic method and, at the same time, overcome the limitations of local search methods that are not suitable for handling multi-optima problems. Case studies on the WSCC 9-bus and New England 39-bus systems indicate that the proposed approach outperforms the existing method in terms of robustness in solution and convergence speed while the solution quality that can offer a more stable and cheaper power supply to customers is achieved.

Local government plays an integral role in the Australian economy with a cumulative annual expenditure of over Aus$20 billion representing around 2% of Australian GDP. Local government authorities employ around 1·3% of the Australian workforce and provide a wide range of services and infrastructure. There is a general lack of appreciation among council staff of the value of collaboration with universities and vice versa. However, staff at Kogarah Municipal Council, having been involved in partnership projects with universities, strongly value the benefits of such collaborations. Councils can provide a ‘one-stop-shop’ for applied research and its application for a range of disciplines from science and technology to arts and policy studies.

View description>>

There is growing consensus worldwide against the conventional centralised approach to water management, and a âsoft pathâ for water management has emerged as a sustainable alternative. A âsoft pathâ for water management emphasizes the optimization of end-use efficiency, small-scaled management systems, incorporates fit-for-purpose water use, and recommends the use of diverse, locally appropriate and commonly decentralised infrastructures. However, large-scale desalination plants are currently being built for almost all metropolitan centres in Australia to ensure water supply security. Unlike âsoft pathâ for water management, large-scale desalination plants embody the traditional urban water supply approach. In spite of knowledge and values relating to the water cycle having shifted towards âsoft pathâ, the old organisational framework is believed to be hindering its adoption. Perhaps, therefore major water utilities in recent times have opted for the ideologically easier option of large-scale desalination conforming to the existing framework, instead of choosing a âsoft pathâ for water management with potential for decentralised management. This paper critically reviews the urban water management direction in metropolitan Australia and puts forward a âgradualist approachâ. It incorporates a comprehensive non-potable water reuse program necessary to build the familiarity and trust in water reuse, as a first step before introducing the idea of potable reuse.

View description>>

Traffic flow information can be employed in an intelligent transportation system to detect and manage traffic congestion. One of the key elements in determining the traffic flow information is traffic density estimation. The goal of traffic density estimation is to determine the density of vehicles on a given road from loop detectors, traffic radars, or surveillance cameras. However, due to the inflexibility of deploying loop detectors and traffic radars, there is a growing trend of using video-content-understanding technique to determine the traffic flow from a surveillance camera. But difficulties arise when attempting to do this in real-time under changing illumination and weather conditions as well as heavy traffic congestions. In this paper, we attempt to address the problem of real-time traffic density estimation by using a stochastic model called Hidden Markov Models (HMM) to probabilistically determine the traffic density state. Choosing a good set of model parameters for HMMs has a significant impact on the accuracy of traffic density estimation. Thus, we propose a novel feature extraction scheme to represent traffic density, and a novel approach to initialize and construct the HMMs by using an unsupervised clustering technique called AutoClass. We show through extensive experiments that our proposed real-time algorithm achieves an average traffic density estimation accuracy of 96.6% over various different illumination and weather conditions.

Web archives preserve the history of autonomous Web sites and are potential gold mines for all kinds of media and business analysts. The most common Web archiving technique uses crawlers to automate the process of collecting Web pages. However, (re)downloading entire collection of pages periodically from a large Web site is unfeasible. In this paper, we take a step towards addressing this problem. We devise a data mining-driven policy for selectively (re)downloading Web pages that are located in hierarchical directory structures which are believed to have changed significantly (e.g., a substantial percentage of pages are inserted to/removed from the directory). Consequently, there is no need to download and maintain pages that have not changed since the last crawl as they can be easily retrieved from the archive. In our approach, we propose an off-line data mining algorithm called near- Miner that analyzes the evolution history of Web directory structures of the original Web site stored in the archive and mines negatively correlated association rules (near) between ancestor-descendant Web directories. These rules indicate the evolution correlations between Web directories. Using the discovered rules, we propose an efficient Web archive maintenance algorithm called warm that optimally skips the subdirectories (during the next crawl) which are negatively correlated with it in undergoing significant changes. Our experimental results with real data show that our approach improves the efficiency of the archive maintenance process significantly whi...

This research investigated the performance of fl oating media fi lter in removing particles and dissolved organic matter from surface water. Pilot-scale study consists of fl oating plastic media pre-fi lter connected with either granular activated carbon (GAC) or sponge biological fi lter (BF) bed. In the fl oating plastic media fi lter, coagulation and fl occulation processes using poly-aluminum chloride (PACl) as coagulant at an optimum dose of 8 mg/L helped removing particles from raw water. The fl oating media fi lter was operated a fi ltration rate of 11 m3/m2.h whereas those in GAC and BF units were maintained at 2 m3/m2.h. Continuous operation for over 120 days gave 98% and 99% average removal effi ciencies of turbidity and UV254 in fl oating media fi lter in combination with GAC unit whereas and 78% and 52% removal effi ciencies of turbidity and UV254 removal were obtained in fl oating media fi lter in combination with BF. The removal of dissolved organic carbon in GAC and BF units reduced chlorine demand for disinfection by 29% and 14%. It could also reduce the sum of trihalomethane (THMs) ratio from 1.1 to 0.1 and 0.5 respectively.

The removal of particulate matter and dissolved organic matter from seawater by the use of biofiltration was investigated. Granular activated carbon (GAC) and anthracite were used as biofilter media at two different filtration velocities. Filtrate quality was measured in terms of silt density index (SDI), modified fouling index (MFI) and turbidity removal. Reverse osmosis (RO) was used as a post-treatment. Both biofilters demonstrated similar fouling reduction behavior in terms of SDI and MFI. Fouling potential in terms of MFI values decreased to 10 s/L2 within the first 10â15 days of operation and kept constant up to the remaining experimental period of 55 days of operation for both GAC and anthracite biofilter. The filtrate turbidity was steady after 10 days and remained low at a value of 0.2â0.3 NTU and 0.28â0.31 NTU for anthracite and GAC biofilter, respectively. Furthermore, the headloss development was low and within 20 cm for biofilter operated at a low velocity of 5 m/h. A post-treatment of reverse osmosis after a pretreatment of GAC and anthracite biofilters showed a reduction in normalized flux decline (J/J0) from 0.22 to 0.12 and 0.35 to 0.21 during the first 20 h, respectively. The RO flux for seawater declined at a faster rate and continued even after 3 days when no pretreatment was provided.

The weird phenomenon of "quantum nonlocality without entanglement" means that local quantum operations assisted by classical communication constitute a proper subset of the class of separable quantum operations. Despite considerable recent advances, little is known to what extent the class of separable operations differs from local quantum operations and classical communication. In this Letter we show that separable operations are generally stronger than local quantum operations and classical communication when distilling a mixed state into a pure entangled state and thus confirm the existence of entanglement monotones that can increase under separable operations. Our finding can also be interpreted as confirming the ability of separable operations to enhance the entanglement of mixed states relative to certain measures, a sensible but important fact that has never been rigorously proven before.

We consider the problem of deciding if a given three-party entangled pure state can be converted, with a non-zero success probability, into a given two-party pure state through local quantum operations and classical communication. We show that this question is equivalent to the well-known computational problem of deciding if a multivariate polynomial is identically zero. Efficient randomized algorithms developed to study the latter can thus be applied to the question of tripartite to bipartite entanglement transformations.

The process of hydrothermal curing or autoclaving is particularly well suited to the utilisation of industrial by-products in the production of construction materials as it renders some of these waste materials highly reactive. Research fi ndings have demonstrated that when used in combination with Portland cement (OPC) in the industrially important CaO-Al2O3-SiO2-H2O system, fi nely ground fi red clay brick masonry, an aluminosilica rich waste, is suitable for the production of autoclaved construction materials. Th e use of kaolin clay as a fi ller in the production of these autoclaved calcium silicate based building products is well established. Th is paper presents a comparative study of fi nely ground clay brick industrial waste and kaolin clay used in combination with OPC under autoclaved conditions. Th e observed variations in compressive strength are discussed in the context of the presence of critical phases, which were characterised by microstructural and thermal analytical methods.

Many of Australia's timber bridges are in aged and decayed conditions. In order to ensure the reliability of these structures and the safety of the public, condition assessment, damage detection and safety evaluation is necessary. This paper presents a damage identification procedure, which is based on global change of vibration characteristics of a structure. The developed method utilises the damage index (DI) method in combination with neural network techniques to identify damage in numerical and experimental timber beam structures. The neural network ensemble approach is utilised in order to respect important diversities of different modes and to integrate individual characteristics of vibrational mode separated damage features. The method considers field testing issues associated with measurement noise, limited number of sensor arrays and environmental fluctuations. The results of damage detection using the proposed approach demonstrate its ability to determine the location and severity of all present damage cases. The outcomes show that the developed damage detection method is effective, robust and reliable.

Dedicated research into the design and construction of a large scale Quantum Information Processing (QIP) system is a complicated task. The design of an experimentally feasible quantum processor must draw upon results in multiple fields; from experimental efforts in system control and fabrication through to far more abstract areas such as quantum algorithms and error correction. Recently, the adaptation of topological coding models to physical systems in optics has illustrated a possible long term pathway to truly large scale QIP. As the topological model has well defined protocols for Quantum Error Correction (QEC) built in as part of its construction, a more grounded analysis of the {\em classical} processing requirements is possible. In this paper we analyze the requirements for a classical processing system, designed specifically for the topological cluster state model. We demonstrate that via extensive parallelization, the construction of a classical 'front-end' system capable of processing error correction data for a large topological computer is possible today.

Quantum error correction (QEC) and fault-tolerant quantum computationrepresent one of the most vital theoretical aspect of quantum informationprocessing. It was well known from the early developments of this excitingfield that the fragility of coherent quantum systems would be a catastrophicobstacle to the development of large scale quantum computers. The introductionof quantum error correction in 1995 showed that active techniques could beemployed to mitigate this fatal problem. However, quantum error correction andfault-tolerant computation is now a much larger field and many new codes,techniques, and methodologies have been developed to implement error correctionfor large scale quantum algorithms. In response, we have attempted to summarizethe basic aspects of quantum error correction and fault-tolerance, not as adetailed guide, but rather as a basic introduction. This development in thisarea has been so pronounced that many in the field of quantum information,specifically researchers who are new to quantum information or people focusedon the many other important issues in quantum computation, have found itdifficult to keep up with the general formalisms and methodologies employed inthis area. Rather than introducing these concepts from a rigorous mathematicaland computer science framework, we instead examine error correction andfault-tolerance largely through detailed examples, which are more relevant toexperimentalists today and in the near future.

Permanent magnet motors are now the focus of application in larger drive and generator systems. They often utilize rare-earth magnets where attractive forces are large and unbalanced magnetic pull (UMP) will be generated even when unexcited. In this paper, a 4-pole machine design is utilized which has either surface magnets or consequent poles. Dynamic eccentricity up to 80% is put into the machine model and a variety of simulations carried out to investigate the UMP. It is found that with strong and thick magnets the machine is robust and the UMP is almost load independent. The consequent pole rotor arrangement produces much higher UMP when the dynamic eccentricity aligns with the steel poles. In the simulations, the different stress components are investigated to assess the validity of a commonly held approximation where the radial force is taken to be a function of the square of the radial air-gap flux.

The biofidelity and performance requirements for a far-side occupant model are described. Previous work is analysed that highlights the potential use of a modified version of the TNO Human Facet Model for simulating far-side impacts. The model's biofidelity and performance are compared with PMHS results from pelvic offset sled tests, pendulum tests and a full-scale far-side crash test. Results indicate that the model exhibits good biofidelity compared with PMHS results, specifically its ability to simulate: belt interaction with the shoulder; loading to the pelvis, thorax and abdomen and whole body kinematics in a full-vehicle far-side crash. The model's main limitations are that its thorax is less capable of matching the magnitude of deflection observed in the PMHS pendulum tests. Copyright © 2009, Inderscience Publishers.

PurposeThe purpose of this paper is to explore the role of trust in the collaborative learning processes that underpin innovation as a competitive strategy in organizations.Design/methodology/approachAs a conceptual paper, the argument is framed by academic perspectives, drawn from the academic literature on the topic and by professional and life experience.FindingsThe collaborative learning practices that underpin idea generation and realization in organizations are strongly dependent for their effectiveness upon the availability, within and beyond stakeholder networks, of trust and other key social capital resources.Practical implicationsIf innovation is dependent upon social capital resources, such as trust, then leadership endeavour needs to be much more focused upon the creation of a social environment that nurtures rich stakeholder and other relevant network, relationships. New forms of governance and power management, and more appropriate and aligned organizational structures, are required in organizations that are attempting to compete through innovation.Originality/valueThe paper's explication of the role of social capital resources, like trust, in organizational innovation offers new insights into this complex but increasingly vital form of competitive strategy.

Traditional subspace analysis methods are inefficient and tend to be affected by noise as they compare the test image to all training images, especifically when there are large numbers of training images. To solve such problem, we propose a fast face recognition (FR) technique called APLDA by combining a novel clustering method affinity propagation (AP) with linear discriminant analysis (LDA). By using AP on the reduced features derived from LDA, a representative face image for each subject can be reached. Thus, our APLDA uses only the representative images rather than all training images for identification. Obviously, APLDA is much more computationally efficient than Fisherface. Also, unlike Fisherface who uses pattern classifier for identification, APLDA performs the identification using AP once again to cluster the test image into one of the representative images. Experimental results also indicate that APLDA outperforms Fisherface in terms of recognition rate. © 2009 Elsevier Inc.

View description>>

This article presents an alternative topology optimization method for the design of compliant actuators using mesh-free methods, in which the thermo-mechanical multi-physics modelling and geometrically non-linear analysis are included. The relatively new mesh-free method rather than the standard finite element method (FEM) is used to discretize the design domain and interpolate the bulk density field, because the mesh-free method is in some cases more capable of modelling the large-displacement compliant mechanisms involving the geometrical non-linearity. An interpolation scheme is used to indicate the dependence of material properties on element pseudo densities which are distributed to the corresponding integration points, and the method for imposing essential boundary conditions in mesh-free methods is also discussed. Furthermore, the adjoint approach is incorporated into the mesh-free method to perform the design sensitivity analysis. The optimization problem is established mathematically as a non-linear programming problem to which a sequential convex programming method is applied. The effectiveness of the proposed method is demonstrated by using a widely studied example.

Duan, R 2009, 'Super-Activation of Zero-Error Capacity of Noisy Quantum Channels'.
View description>>

We study various super-activation effects in the following zero-error communication scenario: One sender wants to send classical or quantum information through a noisy quantum channel to one receiver with zero probability of error. First we show that there are quantum channels of which a single use is not able to transmit classical information perfectly yet two uses can. This is achieved by employing entangled input states between different uses of the given channel and thus cannot happen for classical channels. Second we exhibit a class of quantum channel with vanishing zero-error classical capacity such that when a noiseless qubit channel or one ebit shared entanglement are available, it can be used to transmit $\log_2 d$ noiseless qubits, where 2d is the dimension of input state space. Third we further construct quantum channels with vanishing zero-error classical capacity when assisted with classical feedback can be used to transmit both classical and quantum information perfectly. These striking findings not only indicate both the zero-error quantum and classical capacities of quantum channels satisfy a strong super-additivity beyond any classical channels, but also highlight the activation power of auxiliary physical resources in zero-error communication.

For a multipartite quantum system of the dimension $d_1\otimes d_2\otimes... d_n$, $d_1\ge d_2\ge...\ge d_n$, is there an entangled state {\em maximum} in the sense that all other states in the system can be obtained from the state through local quantum operations and classical communications (LOCC)? When $d_1\ge\Pi_{i=2}^n d_i$, such state exists. We show that this condition is also necessary. Our proof, somewhat surprisingly, uses results from algebraic complexity theory.

In this paper, we study the distinguishability of multipartite quantum states by separable operations. We first present a necessary and sufficient condition for a finite set of orthogonal quantum states to be distinguishable by separable operations. An analytical version of this condition is derived for the case of (D - 1) pure states, where D is the total dimension of the state space under consideration. A number of interesting consequences of this result are then carefully investigated. Remarkably, we show there exists a large class of 2 ⊗ 2 separable operations not being realizable by local operations and classical communication. Before our work, only a class of 3⊗ 3 nonlocal separable operations was known [Bennett et al, Phys. Rev. A 59, 1070 (1999)]. We also show that any basis of the orthogonal complement of a multipartite pure state is indistinguishable by separable operations if and only if this state cannot be a superposition of one or two orthogonal product states, i.e., has an orthogonal Schmidt number not less than three, thus generalize the recent work about indistinguishable bipartite subspaces [Watrous, Phys. Rev. Lett. 95, 080505 (2005)]. Notably, we obtain an explicit construction of indistinguishable subspaces of dimension 7 (or 6) by considering a composite quantum system consisting of two qutrits (resp., three qubits), which is slightly better than the previously known indistinguishable bipartite subspace with dimension 8. © 2009 IEEE.

Recently a mouse model of T/natural killer acute lymphoblastic leukemia was used to assess global promoter methylation across the mouse genome using the restriction landmark genomic scanning technique. One of the methylated mouse genes identified in this way was Slit2. There are three mammalian SLIT genes (SLIT1, SLIT2, SLIT3), that belong to a highly conserved family of axon guidance molecules. We have previously demonstrated that SLIT2 is frequently inactivated in lung, breast, colorectal and glioma tumors by hypermethylation of a CpG island in its promoter region, whilst inactivating somatic mutations are rare. Furthermore, we demonstrated that SLIT2 acts as a tumor suppressor gene in breast and colorectal cancer cells. In this report we determined the methylation status of the SLIT2 gene in leukemias (CLL and ALL). SLIT2 was methylated in all ten leukemia cell lines analyzed (eight completely and two partially methylated). SLIT2 expression was restored after treating ALL lines with 5-aza-2dC. In primary ALL and CLL samples, SLIT2 was also frequently methylated, 58% (30/52) B-ALL; 83% (10/12) T-ALL and in 80% (24/30) CLL. Whilst DNA from peripheral blood and bone marrow from healthy control samples showed no SLIT2 methylation. Methylation results in leukemia cell lines and ALL and CLL primary samples were confirmed by direct sequencing of bisulfite modified DNA. Our results demonstrate that methylation of the SLIT2 5′ CpG island is conserved between mice and humans, and therefore is likely to be of functional importance. © 2009 Landes Bioscience.

We used a chromosome 3 wide NotI microarray for identification of epigenetically inactivated genes in childhood acute lymphoblastic leukemia (ALL). Three novel genes demonstrated frequent methylation in childhood ALL. PPP2R3A (protein phosphatase 2, regulatory subunit B", α) was frequently methylated in T (69%) and B (82%)-ALL. Whilst FBLN2 (fibulin 2) and THRB (thyroid hormone receptor, β) showed frequent methylation in B-ALL (58%; 56% respectively), but were less frequently methylated in T-ALL (17% for both genes). Recently it was demonstrated that BNC1 (Basonuclin 1) and MSX1 (msh homeobox 1) were frequently methylated across common epithelial cancers. In our series of childhood ALL BNC1 was frequently methylated in both T (77%) and B-ALL (79%), whilst MSX1 showed T-ALL (25%) specific methylation. The methylation of the above five genes was cancer specific and expression of the genes could be restored in methylated leukemia cell lines treated with 5-aza-2′-deoxycytidine. This is the first report demonstrating frequent epigenetic inactivation of PPP2R3A, FBLN2, THRB, BNC1 and MSX1 in leukemia. The identification of frequently methylated genes showing cancer specific methylation will be useful in developing early cancer detection screens and for targeted epigenetic therapies. © 2009 Landes Bioscience.

This article reports on an m-learning research agenda instituted at our university in order to explore how mobile technology can enhance active, experiential learning. Details of the implementation and results of four areas of m-learning are presented: mobile supported fieldwork, fostering interactivity in large lectures with mobile technology, using mobile devices to learn about mobile technology and, finally, podcasting. These directions are informed by a concern for achieving m-learning practices consistent with sound educational theory and the needs of the contemporary, technologically aware student body. All four implementations have been successfully embedded in mainstream subjects on a continuing basis. Therefore they represent a departure from the project based approach of much m-learning reported in the literature. This outcome was achieved through a focus on the economic sustainability and feasibility of each case. An evaluation focusing on how well each case assisted students' learning found that, with the exception of lecture podcasting, all supported high quality experiential learning.

This paper addresses one of the main barriers to the widespread adoption of mobile learning in higher education, that of cost. Usage charges billed by telecommunications providers and the cost of mobile hardware are identified as the key cost issues. However, opportunities to overcome this barrier include the high rate of ownership of mobile phones by university students and technological solutions such as packet transmission technologies. The authors describe two experiments in low-cost mobile learning: one that uses packet technology (mobile WAP/WML) to build low-cost interactivity in the classroom and the second that involves mobile-supported fieldwork using several cost-saving strategies. © 2009 Inderscience Enterprises Ltd.

Physiological data is monitored and displayed on medical devices around the world every day, and the volume of this data is steadily increasing and newer monitoring devices enter the clinical setting. However, the vast majority of this data is lost since it is most often displayed once as it is recorded, perhaps replayed one or more times while it exists in the device's volatile memory. What little data that is permanently recorded is most commonly saved through hand written annotations, in paper records and in some limited samples stored on hospital clinical information systems. Meanwhile, current methods of data analysis provide opportunities to utilize this data for improved care of these same critical care patients. A major inhibitor to this becoming reality is the lack of standards for the representation, transmission and storage of physiological data. HL7, for example, does not include definitions for time series data. Research into the use of these data will soon be reaching the clinical setting and the need for such standards to be defined is becoming urgent.

Australia is the driest continent on earth and despite this the installed desalination capacity is still around 1% of the total world's desalination capacity. This paper reviews the main seawater issues considered in every desalination projectâthe history, the present situation and the future of desalination in Australia, the suitability of applying reverse osmosis (RO) and the project details of two desalination plants (Sydney and Perth). Ocean currents, seawater temperature and salinity are signifi cant indicators in the assessment of the feasibility of desalination as they aff ect the production costs, the maintenance frequency and the quality of the product water. Seawater reverse osmosis (SWRO) is the only type of desalination technology currently used or proposed for future large-scale desalination plants in Australia. Every capital city except Darwin has considered building at least one desalination plant as a means of providing water security after several years of unprecedented drought that has signifi cantly reduced dam storage levels. Perth was the fi rst major city to use desalinated water for drinking water supply and by early 2009 Sydney will be the second city. Thirteen other large-scale SWRO plants are being planned or proposed at several locations for the purpose of supplying drinking water.

This work is an attempt to study, with an experimental approach the effect of corrosion on the dynamic behaviour of the reinforced concrete structures by measuring the Eigen frequencies. For this purpose a test was applied on reinforced concrete healthy and corroded beams subjected to a vibratory mechanical excitation. For this test we made use of a vibrating pot and a signal analyzer. The spectral response of each beam gives information in the form of a signal which allows the measurement of these Eigen frequencies so that one can determine the effect of corrosion on the dynamic behaviour of the beam which represents the originality of our experimental approach. © 2009 Praise Worthy Prize S.r.l. - All rights reserved.

We study the problem of evaluating xpath queries over xml data that is stored in an rdbms via schema-based shredding. The interaction between recursion (descendants-axis) in xpath queries and recursion in dtds makes it challenging to answer xpath queries using rdbms. We present a new approach to translating xpath queries into sql queries based on a notion of extended XP ath expressions and a simple least fixpoint (lfp) operator. Extended xpath expressions are a mild extension of xpath, and the lfp operator takes a single input relation and is already supported by most commercial rdbms. We show that extended xpath expressions are capable of capturing both dtd recursion and xpath queries in a uniform framework. Furthermore, they can be translated into an equivalent sequence of sql queries with the lfp operator. We present algorithms for rewriting xpath queries over a (possibly recursive) dtd into extended xpath expressions and for translating extended xpath expressions to sql queries, as well as optimization techniques. The novelty of our approach consists in its capability to answer a large class of xpath queries by means of only low-end rdbms features already available in most rdbms, as well as its flexibility to accommodate existing relational query optimization techniques. In addition, these translation algorithms provide a solution to query answering for certain (possibly recursive) xml views of xml data. Our experimental results verify the effectiveness of our techniques. © 2009 Springer-Verlag.

Using native vegetation to improve soil stiffness, stabilise slopes and control erosion is a rapidly evolving process. A theoretical model previously developed by the authors for the rate of tree root water uptake together with an associated numerical simulation is used to study the effects of a wide range of soil, tree, and atmospheric parameters on partially saturated ground. The influence of different parameters on the maximum initial rate of root water uptake is investigated through parametric and sensitivity analyses. Field measurements taken from previously published literature are compared with numerical predictions for validation. The rate of selected parameters such as potential transpiration and its distribution, suction at wilting point, the coefficient of permeability and the distribution of root length density are studied in detail. The analysis shows that the rate of potential transpiration increases the soil matric suction and ground settlement, while the potential transpiration rate has an insignificant effect on the distribution of soil suction. Root density distribution factors affect the size of the influence zone. Suction at the wilting point increases the soil matric suction and ground settlement, whereas the saturation permeability decreases the maximum soil matric suction generated. The analysis confirms that the most sensitive parameters, including the coefficients of the tree root system, the transpiration rate, the permeability of the soil and its suction at the wilting point should be measured or estimated accurately for an acceptable prediction of ground conditions in the vicinity of trees. © 2009 Elsevier B.V.

Multipartite quantum states that cannot be uniquely determined by their reduced states of all proper subsets of the parties exhibit some inherit `high-order' correlation. This paper elaborates this issue by giving necessary and sufficient conditions for a pure multipartite state to be locally undetermined, and moreover, characterizing precisely all the pure states sharing the same set of reduced states with it. Interestingly, local determinability of pure states is closely related to a generalized notion of Schmidt decomposition. Furthermore, we find that locally undetermined states have some applications to the well-known consensus problem in distributed computation. To be specific, given some physically separated agents, when communication between them, either classical or quantum, is unreliable and they are not allowed to use local ancillary quantum systems, then there exists a totally correct and completely fault-tolerant protocol for them to reach a consensus if and only if they share a priori a locally undetermined quantum state

Building on earlier work, we further develop a formalism based on the mathematical theory of frames that defines a set of possible phase-space or quasi-probability representations of finite-dimensional quantum systems. We prove that an alternate approach to defining a set of quasi-probability representations, based on a more natural generalization of a classical representation, is equivalent to our earlier approach based on frames, and therefore is also subject to our no-go theorem for a non-negative representation. Furthermore, we clarify the relationship between the contextuality of quantum theory and the necessity of negativity in quasi-probability representations and discuss their relevance as criteria for non-classicality. We also provide a comprehensive overview of known quasi-probability representations and their expression within the frame formalism.

A unification of the set of quasiprobability representations using the mathematical theory of frames was recently developed for quantum systems with finite-dimensional Hilbert spaces, in which it was proven that such representations require negative probability in either the states or the effects. In this article we extend those results to Hilbert spaces of infinite dimension, for which the celebrated Wigner function is a special case. Hence, this article presents a unified framework for describing the set of possible quasiprobability representations of quantum theory, and a proof that the presence of negativity is a necessary feature of such representations.

AbstractThis study attempted to address the following questions: for an individual who is at present nonosteoporotic, given their current age and BMD level, what is the individual's risk of fracture and when is the ideal time to repeat a BMD measurement? Nonosteoporotic women (n = 1008) and men (n = 750) over the age of 60 in 1989 from the Dubbo Osteoporosis Epidemiology Study were monitored until one of the following outcomes occurred: (1) BMD reached “osteoporosis” level (i.e., T‐scores ≤ −2.5) or (2) an incident fragility fracture. During the follow‐up period (average, 7 yr), 346 women (34%) and 160 men (21%) developed osteoporosis or sustained a low‐trauma fracture. The risk of osteoporosis or fracture increased with advancing age (women: RR/10 yr, 1.3; 95% CI, 1.1–1.6; men: RR/10 yr, 2.3; 95% CI, 1.7–2.9) and lower BMD levels (women: RR per −0.12 g/cm2, 3.2; 95% CI, 2.6–4.1; RR per −0.12 g/cm2, 2.6; 95% CI, 2.0–3.3). Using the predicted risk (of osteoporosis or fracture) of 10% as a cut‐off level for repeating BMD measurement, the estimated time to reach the cut‐off level varied from 1.5 (for an 80‐yr‐old woman with a T‐score of −2.2) to 10.6 yr (for a 60‐yr‐old man with a T‐score of 0). These results suggest that, based on an individual's current age and BMD T‐score, it is possible to estimate the optimal time to repeat BMD testing for the individual. The prognostic model and approach presented in this study may help improve the individualization and management of osteoporosis.

View description>>

A new method called the random factor method (RFM) for the natural frequency, mode shape and random vibration analysis of stochastic truss structures is presented in this paper. Using the RFM, the structural physical parameters and geometry can be considered as random variables. The structural stiffness and mass matrices can then, respectively, be described by the product of two parts corresponding to the random factors and the deterministic matrix. The structural natural frequencies, mode shapes and random response can be expressed as the function of the random factors. By means of the random variable's functional moment method and the algebra synthesis method, computational expressions for the mean value, standard deviation and variation coefficient of the dynamic characteristics, mean square value of the stationary random displacement and stress response are developed. The influences of the randomness of the structural parameters on the dynamic characteristics, structural displacement and stress responses are demonstrated using a truss structure and Monte-Carlo simulations illustrate the efficiency of the proposed method.

In a bilevel decision problem, both the leader and the follower may have multiple objectives, and the coefficients involved in these objective functions or constraints may be described by some uncertain values. To express such a situation, a fuzzy multi-objective bilevel (FMOBL) programming model and related solution methods are introduced. This research develops a FMOBL decision support system through implementing the proposed FMOBL methods.

AbstractA partially reflective metamaterial surface is designed to have in‐phase reflection property for the purpose of reducing the height of resonant cavity antennas. Since the reflection phase of the in‐phase is close to 0° at the operating band, the cavity height, that is, the distance between the metamaterial surface and the PEC ground, can be reduced from half wavelength to about a quarter wavelength, without using an artificial magnetic conductor as the ground. An example antenna is designed, fabricated, and measured to demonstrate the concept. © 2009 Wiley Periodicals, Inc.

this paper puts forward a design procedure and proposes, in the form of an amendment to Section 5 of AS1720.1-1997, to include these directives in a future edition of the design code. The design procedure discussed herein is thorough in scope and straightforward in application. It addresses the composite characteristics of SSP structures - composite action and tributary width of the sheathing. It provides clear guidelines for the assessment of both aspects. It also imposes a systematic verification of the different stresses experienced by the structure. This particular section of the design procedure considers both AS1720.1-1997 and Eurocode 5 (European Committee for Standardisation, 1995). In addition, a method to account for the two-way action ability of SSP structures is also proposed in the design procedure, which includes two equations derived by Gerber (2007). For defined applications, acceptable assessments of the load distribution in SSP systems are achieved with these two equations for loading on an exterior and interior joist, respectively.

© 2009 Taylor & Francis. The oxidation of sulphides in acid sulphate soils (ASS) causes the acidification of many Australian coastal river systems. The acidity negatively impacts upon coastal ecosystems, aquaculture, agriculture and concrete and steel infrastructure. In the low-lying floodplains, relatively deep surface drains fitted with one-way floodgates lower the watertable, thereby exposing the sulphidic minerals to oxidation. On the Broughton Creek floodplain in SE Australia, four distinct remediation strategies have been developed to tackle the issue of acidification by ASS: (i) simple V-notch weirs that raise the level of the watertable surrounding the drains thereby submerging the pyrite and preventing the further formation of acidity; (ii) modified two-way floodgates that allow the inflow of tidal water into the drains, thereby buffering the acidity within the drain before it enters the river and raising the level of the watertable surrounding the drain; (iii) lateral impermeable lime barriers that both prevent oxidation of pyrite by stopping the downward movement of oxygen into the soil and neutralise the acidity in the groundwater; and (iv) permeable reactive barriers (PRB) that passively intercept the groundwater flow and neutralise the acidity. Each remediation strategy has a distinct role to suit the different terrain and groundwater conditions.

Research into the analysis and monitoring of steroidal estrogens has grown significantly over the last decade, resulting in the emergence of a range of applicable techniques. In this study, three popular techniques, gas chromatographymass spectrometry (GCMS), gas chromatographytandem mass spectrometry (GCMSMS) and liquid chromatographytandem mass spectrometry (LCMSMS) for the analysis of three highly potent steroidal estrogens in the aquatic environment have been compared. It has been observed that overall, the three techniques appear comparable in generating similar estrogen concentrations for river and effluent samples. Of the three techniques, the GCMS technique is the simplest to operate, but fails to detect the estrogens at the lower-end of environmentally relevant concentrations. The tandem MS techniques are more selective than MS, and therefore able to detect lower concentration levels of the three steroidal estrogens of interest. However, the LCMSMS technique is more susceptible to matrix interferences for the analysis of samples, resulting in a reduction of the signal-to-noise ratio and a subsequent reduction in reliability and stability compared to GCMSMS. With the GCMSMS technique offering increased selectivity, the lowest limits of detection, and no false positive identification, it is recommended to be the preferred analytical technique for routine analysis of estrogens in environmental water samples.

Psychologists have long explored mechanisms with which humans recognize other humans' affective states from modalities, such as voice and face display. This exploration has led to the identification of the main mechanisms, including the important role played in the recognition process by the modalities' dynamics. Constrained by the human physiology, the temporal evolution of a modality appears to be well approximated by a sequence of temporal segments called onset, apex, and offset. Stemming from these findings, computer scientists, over the past 15 years, have proposed various methodologies to automate the recognition process. We note, however, two main limitations to date. The first is that much of the past research has focused on affect recognition from single modalities. The second is that even the few multimodal systems have not paid sufficient attention to the modalities' dynamics: The automatic determination of their temporal segments, their synchronization to the purpose of modality fusion, and their role in affect recognition are yet to be adequately explored. To address this issue, this paper focuses on affective face and body display, proposes a method to automatically detect their temporal segments or phases, explores whether the detection of the temporal phases can effectively support recognition of affective states, and recognizes affective states based on phase synchronization/alignment. The experimental results obtained show the following: 1) affective face and body displays are simultaneous but not strictly synchronous; 2) explicit detection of the temporal phases can improve the accuracy of affect recognition; 3) recognition from fused face and body modalities performs better than that from the face or the body modality alone; and 4) synchronized feature-level fusion achieves better performance than decision-level fusion.

Sponge not only can reduce membrane fouling by means of mechanical cleaning and maintain a balance of suspended-attached microorganisms in submerged membrane bioreactor (SMBR), but also can enhance dissolved organic matter and nutrient removal. This study investigated the performance of three different sizes of sponge (S28â30/45R, S28â30/60R and S28â30/90R) associated with continuous aerated SMBR. A laboratory-scale single stage sponge-SMBR (SSMBR) showed high performance for removing dissolved organic matter (>96%) and PO4âP (>98.8), while coarse sponges such as S28â30/45R, S28â30/60R could achieve more than 99% removal of NH4âN. When three-size sponges (S28â30/45R, S28â30/60R and S28â30/90R) were mixed at a ratio of 1:1:1 and in conjunction with two kinds of membranes (0.1 μm hollow fiber and 2 μm nonwoven), the SSMBR system has proved its generic merits of superior treated effluent quality and less membrane fouling. The NH4âN and PO4âP removal were found excellent, which were more than 99.8% and over 99% respectively. Molecular weight distribution also indicated that major fractions of organic matter could be successfully removed by SSMBR.

Soft magnetic composite (SMC) materials and SMC electromagnetic devices have undergone substantial development in the past decade. Much work has been conducted on designing and prototyping various types of electrical machine. However, the iron cores were often made by cutting existing SMC preforms that were formed by compacting SMC powder in simple cylinder or bar-shape molds, and the magnetic properties of the cores may deteriorate significantly during the cutting process. To investigate 'industry production-ready' products, this paper presents the design and analysis of a claw-pole permanent magnet (PM) motor with a molded SMC core of low mass density to replace the existing induction motor in a dishwasher pump. The magnetic properties of the molded SMC core are measured and utilized in the motor design and analysis. Finite element analysis (FEA) of magnetic field is carried out to accurately determine key motor parameters, and an improved phase variable model is applied to predict the motor performance. Both parameter computation and performance prediction are validated by the experimental results on the prototype. © 2009 IEEE.

This research aims to uncover the perceptions of first-year Confucian-heritage students towards their lived experience of university study in Australia. Data was gathered from the students via interviews and analyzed using a phenomenological approach. From the students perspective, prior experience of western-style pedagogy was found to be helpful in giving students an idea of what the Australian learning environment would entail, although many students still had difficulty with classroom interaction due to persistent cultural conditioning. In terms of teacher behaviour, important factors include the lecturer demonstrating an understanding of the students culture, using humour in teaching, being a role model, developing a good relationship with the student and demonstrating a commitment to their learning. Issues included the students lack of understanding of the true significance of assignments and lecturers misunderstanding of the valuable role of memorization in Confucian-heritage students learning. The findings of this work allow academics an insight into the lived educational experiences of the student participants. They may also be tentatively offered as a means of informing future course design and delivery, with the goal of improving the quality of student learning and, therefore, academic success.

Although the perturbation of either the dopaminergic system or brain-derived neurotrophic factor (BDNF) levels has been linked to important neurological and neuropsychiatric disorders, there is no known signaling pathway linking these two major players. We found that the exclusive stimulation of the dopamine D1–D2 receptor heteromer, which we identified in striatal neurons and adult rat brain by using confocal FRET, led to the activation of a signaling cascade that links dopamine signaling to BDNF production and neuronal growth through a cascade of four steps: ( i ) mobilization of intracellular calcium through Gq, phospholipase C, and inositol trisphosphate, ( ii ) rapid activation of cytosolic and nuclear calcium/calmodulin-dependent kinase IIα, ( iii ) increased BDNF expression, and ( iv ) accelerated morphological maturation and differentiation of striatal neurons, marked by increased microtubule-associated protein 2 production. These effects, although robust in striatal neurons from D5 −/− mice, were absent in neurons from D1 −/− mice. We also demonstrated that this signaling cascade was activated in adult rat brain, although with regional specificity, being largely limited to the nucleus accumbens. This dopaminergic pathway regulating neuronal growth and maturation through BDNF may have considerable significance in disorders such as drug addiction, schizophrenia, and depression.

Since 2001, the International Institute of Women in Engineering (IIWE) at EPF, Ecole d'ingenieurs generaliste, Sceaux, France, has conducted a 3 week short course for culturally and discipline diverse, recently graduated and final year engineering students. The aim of this course is to introduce young engineers to broad global concepts and issues relating to their future professional practice, through intercultural learning. The initial course programme provided examples of engineering practices in various countries throughout the world. However, to achieve an intercultural, multidisciplinary learning outcome, a specific course theme and a project focussing on sustainable engineering and the inclusion of a variety of industrial visits were introduced in 2006. This paper will discuss the success of the strategies used to engage international students in the IIWE course activities, and after consideration of the results of participant surveys, the curriculum initiatives that followed

Abstract Background The Ras-assocation family (RASSF) of tumour suppressor genes (TSGs) contains 10 members that encode proteins containing Ras-assocation (RA) domains. Several members of the RASSF family are frequently epigenetically inactivated in cancer, however, their role in leukaemia has remained largely uninvestigated. Also, RASSF10 is a predicted gene yet to be experimentally verified. Here we cloned, characterised and demonstrated expression of RASSF10 in normal human bone marrow. We also determined the methylation status of CpG islands associated with RASSF1–10 in a series of childhood acute lymphocytic leukaemias (ALL) and normal blood and bone marrow samples. Results COBRA and bisulphite sequencing revealed RASSF6 and RASSF10 were the only RASSF members with a high frequency of leukaemia-specific methylation. RASSF6 was methylated in 94% (48/51) B-ALL and 41% (12/29) T-ALL, whilst RASSF10 was methylated in 16% (8/51) B-ALL and 88% (23/26) T-ALL. RASSF6 and RASSF10 expression inversely correlated with methylation which was restored by treatment with 5-aza-2'deoxycytidine (5azaDC). Conclusion This study shows the hypermethylation profile of RASSF genes in leukaemias is distinct from that of solid tumours and represents the first report of inactivation of RASSF6 or RASSF10 in cancer. These data show epigenetic inactivation of the candidat...

This paper describes an improved method for the extraction and analysis of seven endocrine disrupting chemicals with wide-ranging polarities from water and sediments using gas chromatographytandem mass spectrometry (GCMS/MS). The analytes were 4-tert-octylphenol, 4-nonylphenol, bisphenol A, estrone, 17ß-estradiol, 17a-ethynylestradiol and 16a-hydroxyestrone. The optimised GCMS/MS method produces increased selectivity and sensitivity compared to GCMS, with limit of detection ranging from 0.01 to 0.49 ng L-1 in water and from 0.05 to 0.14 ng g-1 in sediment. Extraction from aqueous samples was performed by solid-phase extraction (SPE) and from sediment samples by microwave-assisted extraction (MAE). The improved method for the clean-up of sediment extracts carried out by SPE enhanced EDC recovery (86102%) while reducing matrix interference and sample drying time. Derivatisation of final sample extracts was achieved using N,O-bis(trimethylsilyl)trifluoroacetamide and pyridine, and their stability was enhanced by reconstituting the derivatised extracts with hexane. The method was validated by spiking experiments which showed good recovery and reproducibility. The method was applied to samples taken from the Medway estuary in Kent, UK, where non-conservative behaviour of EDCs was demonstrated.

This paper considers the problem of exponential stability and stabilization of switched linear time-delay systems. The system parameter uncertainties are time-varying and unknown but norm-bounded. The delay in the system states is also time-varying. By using an improved Lyapunov-Krasovskii functional, a switching rule for the exponential stability and stabilization is designed in terms of the solution of Riccati-type equations. The approach allows for computation of the bounds that characterize the exponential stability rate of the solution. Numerical examples are given to illustrate the results.

The application of semiconductor photocatalysis in treating wastewater has attracted growing interest due to its complete mineralisation of organic matter. Furthermore, coupling of photocatalytic process with microfiltration provided considerable advantages over the conventional methods. In this study, the photocatalytic reactivity of the catalysts was assessed at different operating conditions. The results show that the dissolved organic carbon (DOC) content was halved at a concentration of 1.0 g/L of TiO2. With the addition of flocculant FeCl3, the oxidation process was significantly improved further by another 30%. The recovery of TiO2 upon photooxidation process was achieved by coupling the photocatalysis reactor with a low energy submerged membrane reactor. The results show superior DOC degradation of more than 80% by this hybrid system. Moreover, it was demonstrated that photosensitization with TiO2/UV could effectively reduce membrane fouling and enhance the permeate flux of the submerged membrane reactor. © 2009 Elsevier B.V.

Background: The association between vegetarian diets and bone mineral density (BMD) is controversial because of conflicting findings from previous studies. Objective: The aim of this study was to estimate the effect of vegetarian diets on BMD by using a meta-analytic approach. Design: A systematic electronic literature search was conducted to identify all relevant articles on the association between vegetarian diet and BMD. Nine studies of 2749 subjects (1880 women and 869 men) were included in the analysis. Traditional and Bayesian methods of meta-analysis were applied to synthesize the data. Results: Overall, BMD was ≈4% lower in vegetarians than in omnivores (95% CI: 2%, 7%) at both the femoral neck and the lumbar spine. Compared with omnivores, vegans had a significantly lower lumbar spine BMD (6% lower; 95% CI: 2%, 9%), which was more pronounced than in lactoovovegetarians (2% lower; 95% CI: 1%, 4%). The probability that BMD was ≥5% lower in vegetarians than in omnivores (or ≈0.3 SD) was 42% for the femoral neck and 32% for the lumbar spine. There was no evidence of publication bias. There was a moderate degree of between-study heterogeneity; the coefficient of heterogeneity varied between 46% and 51%. Conclusion: The results suggest that vegetarian diets, particularly vegan diets, are associated with lower BMD, but the magnitude of the association is clinically insignificant. © 2009 American Society for Nutrition.

We give trade-offs between classical communication, quantum communication, and entanglement for processing information in the Shannon-theoretic setting. We first prove a unit-resource capacity theorem that applies to the scenario where only the above three noiseless resources are available for consumption or generation. The optimal strategy mixes the three fundamental protocols of teleportation, super-dense coding, and entanglement distribution. We then provide an achievable rate region and a matching multi-letter converse for the direct static capacity theorem. This theorem applies to the scenario where a large number of copies of a noisy bipartite state are available (in addition to consumption or generation of the above three noiseless resources). Our coding strategy involves a protocol that we name the classically-assisted state redistribution protocol and the three fundamental protocols. We finally provide an achievable rate region and a matching mutli-letter converse for the direct dynamic capacity theorem. This theorem applies to the scenario where a large number of uses of a noisy quantum channel are available in addition to the consumption or generation of the three noiseless resources. Our coding strategy combines the classically-enhanced father protocol with the three fundamental unit protocols.

Though the entanglement-assisted formalism provides a universal connection between a classical linear code and an entanglement-assisted quantum error-correcting code (EAQECC), the issue of maintaining large amount of pure maximally entangled states in constructing EAQECCs is a practical obstacle to its use. It is also conjectured that the power of entanglement-assisted formalism to convert those good classical codes comes from massive consumption of maximally entangled states. We show that the above conjecture is wrong by providing families of EAQECCs with an entanglement consumption rate that diminishes linearly as a function of the code length. Notably, two families of EAQECCs constructed in the paper require only one copy of maximally entangled state no matter how large the code length is. These families of EAQECCs that are constructed from classical finite geometric LDPC codes perform very well according to our numerical simulations. Our work indicates that EAQECCs are not only theoretically interesting, but also physically implementable. Finally, these high performance entanglement-assisted LDPC codes with low entanglement consumption rates allow one to construct high-performance standard QECCs with very similar parameters.

A full-scale mock-up for MR shock absorber characterized with multistage slotted and smoothness disposal under impact load was firstly established. Considering the dynamic of MR shock absorber under impact load, an inertia factor was introduced to Herschel-Bulkley model, which led to two revised models, named as Herschel-Bulkley-Inertia model. And a suit of real-time measuring and controlling simulation experimental platform including hardware and software for dynamic response of MR gun recoil shock absorber under impact load was developed. The parameters in Bingham-Inertia model and Herschel-Bulkley-Inertia model were identificated by using the testing data. Further, the testing results prove that the designed MR gun recoil long-stroke shock absorber's dynamic performance under impact load can be well controlled by changing the applied current, and the dynamic response models for MR gun recoil shock absorber under impact load are proved.

A gun recoil magneto-rheological (MR) damper under impact load was researched. A full-scale gun recoil MR damper with long-stroke, multistage slotted and smoothness disposal was designed. The coupling problem between structure and magnetic circuit for MR recoil damper was solved by the electromagnetic field finite element analysis software, and the electromagnetic field distribution of the designed gun recoil MR damper was also analyzed under different conditions, such as coil ringing direction, plunger and steel cylinder part's material selection, dampen channel, smoothness and chamfering disposal, etc. The magnetic circuit design rules of MR recoil damper under high impact load were also concluded. The simulation results indicate that the performance of the designed gun recoil damper satisfy the design requirements.

This paper presents a new map joining algorithm and a set of metrics for evaluating the performance of mapping techniques. The input to the new map joining algorithm is a sequence of local maps containing the feature positions and the final robot pose in a local frame of reference. The output is a global map containing the global positions of all the features but without any robot poses. The algorithm is built on the D-SLAM mapping algorithm (Wang et al. in Int. J. Robot. Res. 26(2):187-204, 2007) and uses iterations to improve the estimates in the map joining step. So it is called Iterated D-SLAM Map Joining (I-DMJ). When joining maps I-DMJ ignores the odometry information connecting successive maps. This is the key to I-DMJ efficiency, because it makes both the information matrix exactly sparse and the size of the state vector bounded by the number of features. The paper proposes metrics for quantifying the performance of different mapping algorithms focusing on evaluating their consistency, accuracy and efficiency. The I-DMJ algorithm and a number of existing SLAM algorithms are evaluated using the proposed metrics. The simulation data sets and a preprocessed Victoria Park data set used in this paper are made available to enable interested researchers to compare their mapping algorithms with I-DMJ.

To evaluate the safety of embankment dams, it is necessary to estimate the erosion rate based on common geotechnical properties such as shear and tensile strength. However, the empirical expressions that are currently available in the literature for this purpose are often inadequate. In this paper, an analytical model is developed to model the erosion of a soil capturing its tensile behaviour based on the law of energy conservation. The erosion rate can be determined using the proposed model if the tensile force - deformation characteristics, dry density, mean particle diameter, and mean flow velocity are known. The proposed model is semi-empirical and can be validated with experimental results obtained from the novel process simulation apparatus for internal crack erosion (PSAICE) designed and built at the University of Wollon- gong, Australia. All tests were conducted on erodible silty sand stabilized with cement and lignosulfonate. The model validation clearly indicates that only a fraction of the energy (efficiency index) from the water stream is effectively used for erosion. © 2009 NRC Canada.

Given the increased demand for freight transport for the mining and agriculture industries, and for greater public transport via trains due to increased fuel costs, heavier cyclic loading on existing tracks is now inevitable. Construction of rail tracks requires appropriate ballast specification to increase stability and performance of railway tracks. This paper aims to demonstrate and discuss some major aspects in relation to stabilisation of ballasted rail tracks overlying soft formation soils using geocomposites, prefabricated vertical drains and native vegetation. The use of geocomposites (ie. bonded geogrid-geotextile layers) for enhancing the performance of fresh and recycled ballast is described, with the aim of achieving reduced track settlement, increased resilient modulus and decreased ballast degradation. The effects of increasing the confi ning pressure on rail track behaviour, particularly with regard to particle breakage, have been studied using large-scale laboratory tests under cyclic loads. An elastoplastic stress-strain constitutive model for ballast was developed at the University of Wollongong, incorporating the degradation of particles as a particular feature, was introduced by capturing the breakage of particles during shearing, and the effects of cyclic loading on particle degradation and plastic deformation. In addition, numerical simulation using discrete element method has been carried out an assembly of irregular particles to investigate the mechanism of ballast breakage and to quantify breakage in relation to the ballast particle size distribution.

Numerous research studies have been carried out in the recent past to determine the influence on the resilient modulus of railway ballast of parameters such as stress history, number of loading cycles, density, grading, fines content, maximum grain size, aggregate type, particle shape and moisture content. However, the influence of particle breakage on the resilient modulus has not been described in depth. The current study highlights the influence of particle breakage on the resilient modulus of latite ballast (commonly used in railway track in New South Wales, Australia). Aggregate degradation is represented by the ballast breakage index (BBI). Laboratory test results indicate that the BBI has a profound influence on the resilient modulus of ballast. The resilient modulus increases with BBI, irrespective of the effective confining pressure. In addition, a simple hyperbolic relationship has been proposed between the resilient modulus MR and the bulk stress φ for latite ballast.

From the symmetry properties electromagnetic response is determined. Magnetic, electric and magnetoelectric modes of the particles are identified along with their isotropy characteristics. Theoretical methods show that all the particles, except monofilar spiral, are non-bianisotropic. Numerical simulation results are presented to verify the analysis. Finally, effective medium theory is applied to extract the effective permeability of the spiral medium. The results indicate negative values for permeability in certain frequency ranges. © 2008 Elsevier B.V. All rights reserved.

Fatigue is a constant occupational hazard for drivers and it greatly reduces efficiency and performance when one persists in continuing the current activity. Studies have investigated various physiological associations with fatigue to try to identify fatigue indicators. The current study assessed the four electroencephalography (EEG) activities, delta (δ), theta (θ), alpha (α) and beta (β), during a monotonous driving session in 52 subjects (36 males and 16 females). Performance of four algorithms, which were: algorithm (i) (θ + α)/β, algorithm (ii) α/β, algorithm (iii) (θ + α)/(α + β), and algorithm (iv) θ/β, were also assessed as possible indicators for fatigue detection. Results showed stable delta and theta activities over time, a slight decrease of alpha activity, and a significant decrease of beta activity (p < 0.05). All four algorithms showed an increase in the ratio of slow wave to fast wave EEG activities over time. Algorithm (i) (θ + α)/β showed a larger increase. The results have implications for detecting fatigue. Impact on industry: The results of this research have the implication for detecting fatigue and can be used for future development of fatigue countermeasure devices. © 2008 Elsevier Ltd.

The effectiveness of different pretreatment on the fouling propensity of the feed was studied using synthetic wastewater. The fouling potential of the feed was characterized by the standard modified fouling index (MFI) and cross-flow sampler modified fouling index (CFSMFI). In CFSMFI, a cross-flow sampler was used to simulate the condition of a cross-flow filtration. The results indicated that the pretreatment such as flocculation with an optimum dose of 68 mg/l FeCl3 substantially reduced the fouling propensity of the feed. The standard MFI of flocculated wastewater was reduced by around 99% compared to that of the untreated wastewater. Similarly, the adsorption with powdered activated carbon (PAC) of 1 g/l reduced the standard MFI value to more than 99% compared to that of the untreated wastewater. The CFSMFI values were lower than the standard MFI values for both treated and untreated wastewater, suggesting that the standard MFI was overestimated. The overestimation of the standard MFI compared to that of the CFSMFI value was more than 99%. The effect of molecular weight distribution (MWD) of the foulants in the wastewater on the fouling propensity of the feed was investigated. The MWD was correlated with the MFI and CFSMFI indices. It yielded useful insights in understanding the effect of MW on MFI and CFSMFI and fouling propensity of the feed.

Non-resonant bifurcations of codimension two may appear in the controlled van der Pol-Duffing oscillator when two critical time delays corresponding to a double Hopf bifurcation have the same value. With the aid of centre manifold theorem and the method of multiple scales, the non-resonant response and two types of primary resonances of the forced van der Pol-Duffing oscillator at non-resonant bifurcations of codimension two are investigated by studying the possible solutions and their stability of the four-dimensional ordinary differential equations on the centre manifold. It is shown that the non-resonant response of the forced oscillator may exhibit quasi-periodic motions on a two-or three-dimensional (2D or 3D) torus. The primary resonant responses admit single and mixed solutions and may exhibit periodic motions or quasi-periodic motions on a 2D torus. Illustrative examples are presented to interpret the dynamics of the controlled system in terms of two dummy unfolding parameters and exemplify the periodic and quasi-periodic motions. The analytical predictions are found to be in good agreement with the results of numerical integration of the original delay differential equation.

A non-resonant interaction of two Hopf bifurcations may appear after the trivial solution of a controlled van der Pol-Duffing oscillator without external excitation loses its stability, when two critical time delays corresponding to two Hopf bifurcations have the same value. In the vicinity of the non-resonant Hopf bifurcations, the presence of a periodic excitation in the controlled oscillator can induce difference resonances in the forced response, when the forcing frequency and the frequencies of the two Hopf bifurcations satisfy certain relationships. It is found that the frequency response curves of the controlled system under difference resonances are an isolated closed curve. The difference resonance response may admit two stable motions on a three-dimensional torus consisting of three frequencies. Illustrative examples are given to show the quasi-periodic motions.

In this paper the performance of single and dual media filters with in-line flocculation have been examined as pretreatment to seawater reverse osmosis (SWRO). A comparison of filter performance was made between single medium filter (80 cm) consisting of sand or anthracite, and dual media filter consisting of sand (40 cm at the bottom) and anthracite (40 cm on top). Short term (6 hours) experiments were conducted with in-line coagulation followed by direct filtration. Filtration velocities of 5 m/h and 10 m/h were used. The performances of these filters were assessed in terms of turbidity removal, head loss build-up, and organic compound removal in terms of molecular weight distribution (MWD). The efficiency of the filter as pretreatment was evaluated in terms of silt density index (SDI) and modified fouling index (MFI). It was found that the turbidity removal was high and all the filters produced more or less same quality water. There was a slower buildup of head loss for coarser filter medium. A post treatment of reverse osmosis after an inline-flocculation-dual media filtration showed lower normalized flux decline (J/J0) (0.35 to 0.22 during the first 20 hours operation) while, seawater without any pretreatment showed steeper flux decline (0.18 to 0.11 at first 20 hours operation) in RO.

In this study, a high-rate fibre filter was used as a pre-treatment to stormwater in conjunction with in-line flocculation. The effect of operating the fibre filter with different packing densities (105, 115 and 125 kg/m3) and filtration velocities (20, 40, 60 m/h) with and without in-line flocculation was investigated. In-line flocculation was provided using 5, 10 and 15 mg/L of ferric chloride (FeCl3·6H2O). The filter performance was studied in terms of pressure drop (ÎP), solids removal efficiency, heavy metals (total) removal efficiency and total organic carbon (TOC) removal efficiency. It is found that the use of in-line flocculation at a dose of 15 mg/L improved the performance of fibre filter as measured by turbidity removal (95%), total suspended solids reduction (98%), colour removal efficiency (99%), TOC removal (reduced by 30â40 %) and total coliform removal (93%). The modified fouling index reduced from 750â950 to 12 s/L2 proving that fibre filter can be an excellent pre-treatment to membrane filtration that may be consider as post-treatment. The removal efficiency of heavy metal was variable as their concentration in raw water was small. Even though the concentration of some of these metals such as iron, aluminium, copper and zinc were reduced, others like nickel, chromium and cadmium showed lower removal rates

This paper presents the results of experiments on the application of dual media and single media deep bed filters as pre-treatments to stormwater. In-line flocculation-filtration experiments were conducted with dual and single media filter. The single filter media (80 cm) consisted of either anthracite or sand, and the dual media filter consisted of sand (40 cm at the bottom) and anthracite (40 cm on top). Filtration velocities of 5 m/h, 10 m/h and 15 m/h were examined. The removal efficiency for turbidity, suspended solids and TOC was found to be 95%, 99% and 30â45% respectively at a flocculant dose of FeCl3 of 15 mg/L. The anthracite filter media showed a lower headloss development (26 cm, operated at 5 m/h filtration velocity with FeCl3 dose of 5 mg/L). The removal efficiency for nitrogen was lower than phosphorus which was relatively good (up to 50%). The removal efficiency for heavy metals such as Cd, Pb, Cr and Ni was found to be very low for all tested filtration systems because concentrations of these metals in the influent were also low. This filter can be used as a pretreatment to a membrane filter as the modified fouling index was reduced from 750 s/L2 (for stormwater) to 15 s/L2 (for filtered effluent). Detailed submerged membrane filter experiments conducted with pre-treated water showed that the membrane filter can be successfully be used as post-treatment to in-line flocculant-filter at a sustainable flux of 10 L/m2.h to remove the remaining solids and pathogens. An increase of air scouring in the membrane unit decreased the pressure development although it did not have any effect on increasing the critical flux beyond 10 L/m2.h.

View description>>

The dynamics of complex social networks has become one of the research areas of growing importance. The knowledge about temporal changes of the network topology and characteristics is crucial in networked communication systems in which accurate predictions are important. The local network topology can be described by the means of network motifs which are small subgraphs - usually containing from 3 to 7 nodes. They were shown to be useful for creating profiles that reveal several properties of the network. In this paper, the time-varying characteristics of social networks, such as the number of nodes and edges as well as clustering coefficients and different centrality measures are investigated. At the same time, the analysis of three-node motifs (triads) was used to track the temporal changes in the structure of a large social network derived from e-mail communication between university employees. We have shown that temporal changes in local connection patterns of the social network are indeed correlated with the changes in the clustering coefficient as well as various centrality measures values and are detectable by means of motifs analysis. Together with robust sampling network motifs can provide an appealing way to monitor and assess temporal changes in large social networks.

Abstract Background The reconstruction of gene regulatory networks from high-throughput 'omics' data has become a major goal in the modelling of living systems. Numerous approaches have been proposed, most of which attempt only 'one-shot' reconstruction of the whole network with no intervention from the user, or offer only simple correlation analysis to infer gene dependencies. Results We have developed MINER (Microarray Interactive Network Exploration and Representation), an application that combines multivariate non-linear tree learning of individual gene regulatory dependencies, visualisation of these dependencies as both trees and networks, and representation of known biological relationships based on common Gene Ontology annotations. MINER allows biologists to explore the dependencies influencing the expression of individual genes in a gene expression data set in the form of decision, model or regression trees, using their domain knowledge to guide the exploration and formulate hypotheses. Multiple trees can then be summarised in the form of a gene network diagram. MINER is being adopted by several of our collaborators and has already led to the discovery of a new significant regulatory relationship with subsequent experimental validation. Conclusion Unlike most gene regulatory network inference methods, MINER allows the user to start from genes of interest and build the network gene-by-gene, incorporating domain expertise in the process. This approach has been used successfully with RNA microarray data but is applicable to other quantitative data produced by high-throughput technologies such as proteomics and 'next generation' DNA s...

Motivated by the success of large margin methods in supervised learning, maximum margin clustering (MMC) is a recent approach that aims at extending large margin methods to unsupervised learning. However, its optimization problem is nonconvex and existing MMC methods all rely on reformulating and relaxing the nonconvex optimization problem as semidefinite programs (SDP). Though SDP is convex and standard solvers are available, they are computationally very expensive and only small data sets can be handled. To make MMC more practical, we avoid SDP relaxations and propose in this paper an efficient approach that performs alternating optimization directly on the original nonconvex problem. A key step to avoid premature convergence in the resultant iterative procedure is to change the loss function from the hinge loss to the Laplacian/square loss so that overconfident predictions are penalized. Experiments on a number of synthetic and real-world data sets demonstrate that the proposed approach is more accurate, much faster (hundreds to tens of thousands of times faster), and can handle data sets that are hundreds of times larger than the largest data set reported in the MMC literature.

This paper presents an efficient trajectory planning approach for a 6DOF robotic manipulator conducting grit-blasting in complex bridge structural environments. The proposed approach extends upon robotic grit-blasting planning and incorporates joint movement minimisation in addition to path length minimisation. A genetic algorithm is implemented to optimise initial path plans based on a heuristic pattern for the coverage of surface areas to be blasted. A customised gradient based method is applied for the generation of collision-free joint configurations for grit-blasting based on the identified path plan. A grit-blasting coverage model is developed for discrete non-planar 3D coverage determination to verify the performance of the plan. Extensive simulation and experimental results are also presented in this paper. © 2009 Inderscience Enterprises Ltd.

This paper presents a system for surface classification using a laser range finder. It is shown that the return intensities and range errors provide sufficient information to distinguish a wide range of surfaces commonly found in a number of environments. A supervised learning scheme (using curves representing the return intensity and range error as a function of angle of incidence) is used to classify the surface type of planar patches. Extensive experimental evidence is presented to demonstrate the potential of the proposed technique. The surface type classification, which uses a typical laser range finder, is targeted for use with autonomous robotic systems in which significantly different interaction is required for each of the various materials present. Results from an on-site experiment demonstrate that the information from the laser range finder is sufficient to identify the different materials (via their surface properties) present in a scene where a bridge structure is being prepared for grit blasting. © 2009 IEEE.

With more satellite systems becoming available there is currently a need for Receiver Autonomous Integrity Monitoring (RAIM) to exclude multiple outliers. While the single outlier test can be applied iteratively, in the field of statistics robust methods are preferred when multiple outliers exist. This study compares the outlier test and numerous robust methods with simulated GPS measurements to identify which methods have the greatest ability to correctly exclude outliers. It was found that no method could correctly exclude outliers 100% of the time. However, for a single outlier the outlier test achieved the highest rates of correct exclusion followed by the MM-estimator and the L1-norm. As the number of outliers increased MM-estimators and the L1-norm obtained the highest rates of normal exclusion, which were up to ten percent higher than the outlier test.

The aim of this paper is to evaluate the performance of the low-flow filtration system (LFFS) that Kogarah Municipal Council developed for treating and reusing the highly polluted first-flush stormwater (FFSW) while allowing the cleaner subsequent major stormwater flows to be directed to the major street drainage. The LFFS was evaluated through laboratory investigations using columns packed with different filter media to test the removal efficiency of pollutants such as zinc (Zn), total phosphorus (TP), total nitrogen (TN), total organic content, total petroleum hydrocarbons (TPH), and turbidity. The findings from this study demonstrate the effectiveness of the LFFS to largely reduce turbidity, TPH, and trace metals from the FFSW. The LFFS also partially removes dissolved organics, TP and TN. These pollutants are more commonly and effectively removed in subsequent processes of a stormwater treatment train. Further this paper highlights the importance of regular maintenance of the LFFS especially as it is only associated in removing the high pollutant loads during a storm event. Due to this first flush, a thick oily crust-formed layer requires monthly removal, and an entire replacement of the exhausted filter media is required quarterly. However considering the labor required to service the crust formed layer within the LFFS, it is more cost effective to replace the entire depth of filter media monthly.

The contrast enhancement of gray-level digital images is considered in this paper. In particular, the mean image intensity is preserved while the contrast is enhanced. This provides better viewing consistence and effectiveness. The contrast enhancement is achieved by maximizing the information content carried in the image via a continuous intensity transform function. The preservation of image intensity is obtained by applying gamma-correction on the images. Since there is always a trade-off between the requirements for the enhancement of contrast and preservation of intensity, an improved multiobjective particle swarm optimization procedure is proposed to resolve this contradiction, making use of its flexible algorithmic structure. The effectiveness of the proposed approach is illustrated by a number of images including the benchmarks and an image sequence captured from a mobile robot in an indoor environment. © 2006 IEEE.

This study investigated the effect of the molecular weight cut-off (MWCO) of a dialysis membrane for the isolation of colloidal organic matter (COM) from surface water. Various dialysis membranes with different MWCO were used for the isolation of COM from Cebron reservoir natural organic matter (CRNOM). The COM included mainly amino sugars (3040%) and polysaccharides (3040%), with 23 of fatty acids over aromatic acids (F=A ratio), indicating that the COM were derived from microbial substances. As all the COM constituents were found to have similar characteristics, the MWCO of the dialysis membrane was not found to influence the COM characteristics.

The aims of this study were to investigate the fouling mechanisms of model organic compounds (MOCs) on two ultrafiltration membranes [composite regenerated cellulose (YM100) and polyethersulfone (PES)] and the relationship between fouling and membrane characteristics, flux decline, and the streaming potential (SP). Two alginic acids (polymer and dimmer, AA), abietic acid (AbA), colominic acid (CA), and N-acetylneuraminic acid (NA) were selected as MOCs to test their membrane fouling potential through flux decline and SP. The fouling caused by the two AAs, which contained many polysaccharides, was the highest among MOCs, but this fouling was external (solute deposition on the membrane surface) and reversible as polysaccharides did not strongly adsorb onto the YM100 and PES membranes. CA also caused external fouling of the two membranes; however, AbA caused internal (solute adsorption on the pores wall of membrane) and irreversible fouling of the PES membrane. NA, which contained amino sugars, exhibited very low fouling of both membranes. The hydrophilic YM100 membrane experienced less fouling than the hydrophobic PES membrane with all MOCs. The measurement of the SP using a modified dead-end filtration cell was employed to evaluate the flux decline due to MOCs.

The paper examines the reliability of masonry walls designed for compression in accordance with AS3700. The results of a large number of tests on full-scale masonry walls in compression have been used to obtain probabilistic models of behaviour. Structural reliability was then estimated for vertical loading of unreinforced masonry walls loaded concentrically, considering variations of unit compressive strength, mortar type, tributary area and live-to-dead load ratios. A reliability-based calibration of the Australian masonry design code AS3700 was then conducted using a target reliability index specified in AS5104. Recommendations are made for changes to $ used for compression design in AS3700 that, if adopted, would lead to an increase of 66% in the design compressive strength of walls. © Institution of Engineers Australia, 2009.

Flocculation using titanium tetrachloride (TiCl4) as a coagulant is an efficient and economical application because the flocculated sludge can be recycled to produce a valuable byproduct, namely titanium dioxide (TiO2) nanoparticles. However, toxicity of TiCl4 has not yet been assessed while it is used in water treatment. The aquatic toxicity of TiCl4 flocculation process was investigated to assess the environmental safety of the coagulant. D. magna and V. fischeri bioassays were carried out to evaluate the supernatant toxicity after TiCl4 flocculation. Artificial wastewater, biologically treated sewage effluent, and seawater were used to study the toxicity of TiCl4 flocculation. Results showed that supernatant toxicity was very low when TiCl4 flocculation was conducted (no observed effect concentration = 100 mg/L and lowest observed effect concentration = 150 mg/L exposed to D. magna and V. fischeri, respectively). Similarly, TiO2 nanoparticles recovered from wastewater and seawater flocculated sludge were also found to have low toxicity. The regenerated TiO2 nanoparticles indicated low toxicity values when compared to the commercial-TiO2 nanoparticle, P-25.

Seawater was drawn from Chowder Bay, Sydney. The eff ect of diff erent pretreatment hybrid systems was investigated in terms of silt density index (SDI10), modifi ed fouling index (MFI), headloss across the fi lters and reduction in turbidity and dissolved organic carbon (DOC). The in-line fl occulation in fi bre fi lter improved the performance of the pretreatment hybrid system as measured by the MFI, SDI10, headloss, turbidity and DOC removal. The lowest SDI10 and MFI were found with a fi bre fi lter operated at a fi ltration velocity of 40 m/h followed by dual media fi lter operated at a fi ltration velocity of 5 m/h. The lowest headloss and turbidity was found with a fi bre fi lter operated at a fi ltration velocity of 40 m/hr followed by anthracite operated at a fi ltration velocity of 5 m/h. This system also gave an effl uent with the lowest DOC of 0.64 mg/L corresponding to a removal effi ciency of about 70%.

Recent breakthroughs in quantum query complexity have shown that any formula of size n can be evaluated with O(sqrt(n)log(n)/log log(n)) many quantum queries in the bounded-error setting [FGG08, ACRSZ07, RS08b, Rei09]. In particular, this gives an upper bound on the approximate polynomial degree of formulas of the same magnitude, as approximate polynomial degree is a lower bound on quantum query complexity [BBCMW01]. These results essentially answer in the affirmative a conjecture of O'Donnell and Servedio [O'DS03] that the sign degree--the minimal degree of a polynomial that agrees in sign with a function on the Boolean cube--of every formula of size n is O(sqrt(n)). In this note, we show that sign degree is super-multiplicative under function composition. Combining this result with the above mentioned upper bounds on the quantum query complexity of formulas allows the removal of logarithmic factors to show that the sign degree of every size n formula is at most sqrt(n).

Handwritten shorthand systems were devised to enable writers to record information on paper at fast speeds, ideally at the speed of speech. While they have been in existence for many years it is only since the 17th Century that widespread usage appeared. Several shorthand systems flourished in the first half of the 20th century until the introduction and widespread use of electronic recording and dictation machines in the 1970's. Since then, shorthand usage has been in rapid decline, but has not yet become a lost skill. Pitman shorthand has been shown to possess unique advantages as a means of fast text entry which is particularly applicable to hand-held devices in mobile environments. This paper presents progress and critical research issues for a Pitman/Renqun Shorthand Online Recognition System. Recognition and transcription experiments are reported which indicate that a correct recognition and transcription rate of around 90% is currently possible.

Superconducting magnetic energy storage (SMES) is a research hotspot in the application field of superconducting materials. Using the property of low loss and fast response of superconducting magnet, SMES is employed as a multifunctional electromagnetic system to store and release the power for power system with the connection of power electronic converters. SMES has capacity to reach the objects, such as storing large amount of energy with very low loss, improving the power supply quality and enhancing the stability and reliability of power system. IEEE TEAM Workshop Problem 22 deals with the optimization design of SMES, which is a benchmark problem including low and high dimensional, discrete and continuous optimization cases. To address this problem, sequential optimization method (SOM) and Kriging model are fully discussed. It can be seen that SOM can obtain satisfactory solutions, and the overall computational effort needed is much less than that by direct optimization method. For the 3 parameters problem, the number of finite element sample points is less than 1/10 compared with that of direct method; and for the 8 parameters problem, that number is about 1/3 compared with that of direct method. So the proposed method can be widely employed in the optimization design problem of electromagnetic devices.

Improved sequential optimization method (SOM) and dimension reduction optimization method (DROM) are presented for high dimensional optimization design problems of electromagnetic devices. Improved SOM can simultaneously optimize the statistical approximate models and optimization algorithms more efficiently compared with SOM. Using DROM, a high dimensional problem can be converted into a low dimensional problem with expert experience or some design of experiment techniques. Then two TEAM benchmark problems (Problem 22 and Problem 25) are investigated to illustrate the efficiency of the proposed methods. From the experimental results, we can see that the presented methods can obviously reduce the computational cost of finite element analysis, while the optimal results also satisfy design specification.

Using Gaussian numerical integration formula, the problem of estimating the particle size distribution (PSD) in ferrofluids can be converted into an electromagnetic inverse problem. Then we present two Bayesian analytical estimators, minimum mean-square error estimator and maximum a posteriori estimator, to reconstruct the PSD of magnetic particles. In the implementation, weighted minimum norm approach, maximum likelihood estimator, and weighted least square estimator are employed to determine prior information for the unknown parameter. We also present two methods to provide the noise information for the error term. Finally, using Monte Carlo method, we give a ferrofluid example to illustrate the efficiency of the proposed methods.

The surface deterioration of 4%Cr with Ti-added roll varies significantly with all increase of rolling passes. Asperities oil roll surface experience inhomogeneous variation, which indicates the deterioration of surface roughness is different for both roll materials.

The interplay between the carbon and other nutrient cycles is the key to understand the responses of soil ecosystems to climatic change. Using the free-air CO2 enrichment (FACE) techniques, we carried out a multifactorial experiment in a Chinese rice-wheat rotation system, to investigate the response of soil nematodes to elevated CO2 under different application rates of N fertilizer (225.0 kg N ha-1 (HN) and 112.5 kg N ha-1(LN), respectively) and residue incorporation (0 kg C ha-1 (ZR), 1000 kg C ha-1 (MR) and 2000 kg C ha-1 (HR), respectively). This study was conducted during the wheat growing season of 2007 after expose to the elevated CO2 for three years. The results in our study indicated that seasonality is an important factor in determining changes in the nematode abundance and diversity. The residue addition effects were more obvious than the elevated CO2, which significantly influenced the abundance of total nematodes and plant-parasites, and some ecological indices. The interactions between residue addition and CO2 significantly influenced nematode dominance and structure indices. High level of N fertilization was found to decrease the nematode diversity, generic richness and maturity indices at wheat jointing stage. There are significant interactions between N fertilization and elevated CO2 for abundance of total nematodes and different trophic groups. © 2009 Elsevier Ltd.

Sequential inference method was presented for engineering electromagnetic optimization by the combination of statistical approximate models with sequential sampling method. In the implementation, approximate models include radial basis model and compactly supported radial basis model; sequential sampling and optimization process is composed of coarse optimization process and fine optimization process. Compared with traditional direct optimization method, the optimization models constructed by the sequential sampling method only need a small sample data, and the overall computational effort needed is much less than that by direct optimization method. Meanwhile, sequential method can provide prior information for the optimization algorithm. Finally, to illustrate the performance of the new method, Monte Carlo simulation experiment and the IEEE TEAM Workshop Problem 22 are investigated. Analysis demonstrates that the computation cost of the new methods is less than 1/10 of direct optimization algorithm. The optimization results are also satisfied the design objectives.

AbstractBy introducing two orthogonal gaps to a uniplanar compact photonic bandgap structure, artificial magnetic conductor's resonance frequencies have been significantly reduced. Since this compact pattern needs slots with 0.05‐mm width, the laser micromachining was explored to fabricate the prototypes. Reflection coefficients were measured through a WR‐137 waveguide. Considering the dominant waves propagating in a waveguide, a simulation method is introduced. © 2009 Wiley Periodicals, Inc.

Hostile dynamic loadings such as severe wind storms, earthquakes, and sudden impacts can cause severe damage to many civil engineering structures. An intelligent structural system equipped with smart structural members that are controllable in real-time is an effective solution to structural damage and failure during such situations. Civil intelligent structures with controllable properties to adapt to any changes due to dynamic loadings can lead to effective protection of structures and their occupants. In this paper, design and testing of a semi-active magnetorheological (MR) pin joint, in which the moment resistance can be controlled in real-time by altering the magnetic field, is reported with the view of using it as a potential candidate for smart members in the development of intelligent structures. Design of prototype smart pin joints includes theoretical analysis related to the radius of the rotary plate, the property of MR fluids and the gap between the rotary plate and the casing based on the requirements of the dynamics of MR pin joints. FEM analysis was deployed to study the distribution of the magnetic field along the gap. It is found, from the theoretical analysis and experimental verification, that the MR pin joint with a diameter of 180 mm can produce a torque of up to 30 Nm, which meets requirements for semi-active members in a multi-storey prototype building model in the next stage of research and development.

This technique could reduce the comb-drive to a group of equivalent lumped parameters finite elements, which capture the input and output device behavior and its static and dynamic characteristics. The complexity of reduced order model was reduced to a great extent and computing time is decreased. The problem of the strongly coupled field is effectively solved by reduced order modeling. The relation between structure parameters and the electrostatic force and the displacement was discussed. Simulation results were validated using a finite element method, which is not reduced, both methods give very similar results, the maximum displacement error is less than 5%.

Drivers' fatigue contributes to traffic accidents, so drivers must maintain adequate alertness. The effectiveness of audio alarms in maintaining driving performance and characteristics of alarms was studied in a virtural reality-based driving environment. Response time to the car's drifting was measured under seven conditions: with no warnings and with continuous warning tones (500 Hz, 1750 Hz, and 3000 Hz), and with tone bursts at 500 Hz, 1750 Hz, and 3000 Hz. Analyses showed the audio warning signals significantly improved driving. Further, the tones' spectral characteristics significantly influenced the effectiveness of the warning.

We develop a new approach for decision making in educational management based on the use of distance measures. We focus on the selection of a studies plan from the perspective of an academic institution. We try to develop this approach showing the benefits of establishing an ideal plan that we compare with the available alternatives. We use the Minkowski distance, the ordered weighted averaging (OWA) operator and the interval numbers. The use of the Minkowski distance allows to make comparisons between the ideal plan and the available ones in the market. The OWA operator is an aggregation operator that provides a parameterized family of aggregation operators that includes the maximum, the minimum and the average criteria, among oth- ers. And the interval numbers is a very useful technique to represent the information when the environment is very complex, because it gives all the possible results from the minimum to the maximum. We introduce a new aggregation operator called the uncertain generalized ordered weighted aver- aging distance (UGOWAD) operator. It is a distance aggregation operator that uses the main characteristics of the Minkowski distance, the OWA op- erator and the interval numbers. We develop an illustrative example where we can see the usefulness of the UGOWAD operator to select a studies plan in education management. The main advantage of using the UGOWAD is that we can consider a wide range of distance aggregation methods in the decision problem. Then, the decision maker gets a more complete view of the decision problem, being able to select the alternative that better fits the interests.

Remote and virtual laboratories are increasingly prevalent alternatives to the face-to-face laboratory experience; however, the question of their learning outcomes is yet to be fully investigated. There are many presumptions regarding the effectiveness of these approaches; foremost amongst these assumptions is that the experience must be 'real' to be effective. Embedding reality into a remote or virtual laboratory can be an expensive and time-consuming task. Significant efforts have been expended to create 3D VRML models of laboratory equipment, allowing students to pan, zoom and tilt their perspective as they see fit. Multiple camera angles have been embedded into remote interfaces to provide an increased sense of 'realness'. This paper draws upon the literature in the field to show that the necessary threshold for reality varies depending upon how the students are interacting with the equipment. There is one threshold for when they first interact - the establishment reality - which allows the students to familiarise themselves with the laboratory equipment, and to build their mental model of the experience. There is, however, a second, lower, threshold - the maintenance reality - that is necessary for the students' ongoing operation of the equipment. Students' usage patterns rely upon a limited subset of the available functionality, focusing upon only some aspects of the reality that has been originally established. The two threshold model presented in this paper provides a new insight for the development of virtual laboratories in the future.

This paper reports on a replication of earlier studies into a possible hierarchy of programming skills. In this study, the students from whom data was collected were at a university that had not provided data for earlier studies. Also, the students were taught the programming language 'Python', which had not been used in earlier studies. Thus this study serves as a test of whether the findings in the earlier studies were specific to certain institutions, student cohorts, and programming languages. Also, we used a non-parametric approach to the analysis, rather than the linear approach of earlier studies. Our results are consistent with the earlier studies. We found that students who cannot trace code usually cannot explain code, and also that students who tend to perform reasonably well at code writing tasks have also usually acquired the ability to both trace code and explain code.

Field measurements reveal that radio link asymmetry has a severe impact on reliable data delivery. We analyze the energy efficiencies of selected reliability schemes for asymmetric radio links using theoretical models. The analysis provides guidelines for retransmission control so as to balance between reliability and energy consumption. We also design two enhancements to the "implicit" ARQ scheme addressing the negative effects of asymmetric radio links. The energy efficiencies of these algorithms are explicitly derived using our theoretical model and validated by simulations and field trials. Based on the analysis of the two enhanced algorithms, we propose an improvement, referred to as Energy Efficient Reliable Data Collection (EERDC) that controls the retransmissions of the enhanced ARQ schemes. Simulations and field trials confirm our theoretical findings and demonstrate that our proposed EERDC algorithm alleviates the impact of link asymmetry and achieves energy savings. © 2009 Springer Science+Business Media, LLC.

There is growing research into, and development of, the use of the internet to support remote access by students to physical laboratory infrastructure. These remote laboratories can, under appropriate circumstances, support or even replace traditional (proximal) laboratories, provide additional or improved access at reduced cost, and encourage interinstitutional sharing of expensive resources. Effective design of remote laboratories requires attention to the design of both the pedagogy and the technical infrastructure, as well as how these elements interact. In this paper, we consider the architectures of remote laboratories, the shortcomings of existing implementations, and we argue that emerging internet technologies can assist in overcoming these shortcomings. We also consider the opportunities which these technologies provide in moving beyond both existing remote laboratories and existing proximal laboratories, to create opportunities which were not previously possible. © 2009 IEEE.

The capability of motion is one of the important aspects for a micro-robot to fulfill its given tasks. Micro-autonomous systems usually require large force, large displacement and less power consumption. Among different actuation schemes, electromagnetic actuator shows the benefit in a combination of force, displacement and cost effective control. A bristle-based inchworm mobile robot using a short stroke electromagnetic linear actuator is described in the paper. The main body and movable unit of the robot are joined by using a sealed bellows and the bristle legs are designed so that it can operate both on plane surfaces and in liquid. The actuator designed for the robot is a tubular type linear machine with an overall size of ?7 × 10 mm. The key dimensions of the actuator were determined through magnetic field analysis to achieve optimum force output and necessary travel stroke within the limited space. The predicted actuation force of the actuator is 20 mN and the stroke length is 1.2 mm. Two working prototypes of the actuator were constructed and the performance tests show the effectiveness of the design. A sensorless control scheme with a novel start-up strategy for the designed actuator was developed based on the robotic system modeling and the analyzed results show the satisfactory performance of the system.

This study applies Bayesian network techniques to analyze and verify the relationships among cost factors and benefit factors in e-service systems. This study first establishes a Bayesian network for e-service cost-benefit factor relationships based on our previous study [Lu, J. & Zhang, G. Q. (2003). Cost benefit factor analysis in e-services. International Journal of Service Industry Management (IJSIM), 14(5), 570-595]. It then calculates conditional probability distributions among these factors shown in the Bayesian network. Finally it runs a Junction-tree algorithm to conduct inference for verifying these cost-benefit factor relationships, and the data collected through a survey is as evidences in the inference process. Through the above application of Bayesian network techniques a set of useful findings is obtained for the costs involved in e-service developments against the benefits received by adopting these e-service systems. The case of 'increased investments in maintaining e-services' would significantly contribute to 'enhancing perceived company image', and the case of 'increased investments in security of e-service systems' would bring high benefits in 'building customer relationships' and 'improving cooperation between companies'. These findings have great potential to improve the strategic planning of businesses by determining more effective investments items and adopting more suitable development activities in e-service systems and applications. © 2008 Elsevier Ltd.

Fabric hand evaluation (FHE) is the main measure in textile material selection for fashion design and development. Fabric hand evaluation requires considering multiple evaluation aspects/criteria by a group of evaluators. Some fabric features can also be measured using instruments. The evaluation often uses linguistic terms in the weights of criteria, and the weights and judgments of evaluators. To support a FHE-based material selection, this study first develops a fabric hand-based textile material evaluation model. It then proposes a human-machine measure integrated fuzzy multi-criteria group decision-making method. A software tool is also developed, which implements the proposed method and is applied in fabric hand-based textile material evaluation. © 2009 Springer Science+Business Media, LLC.

This paper proposes an efficient method for detecting ghost and left objects in surveillance video, which, if not identified, may lead to errors or wasted computational power in background modeling and object tracking in video surveillance systems. This method contains two main steps: the first one is to detect stationary objects, which narrows down the evaluation targets to a very small number of regions in the input image; the second step is to discriminate the candidates between ghost and left objects. For the first step, we introduce a novel stationary object detection method based on continuous object tracking and shape matching. For the second step, we propose a fast and robust inpainting method to differentiate between ghost and left objects by reconstructing the real background using the candidate's corresponding regions in the current input and background image. The effectiveness of our method has been validated by experiments over a variety of video sequences and comparisons with existing state-of-art methods.

Timely detecting information inconsistencies (anomalies) in real-time information provides strong support for decision-making in a dynamic decision-making situation. Existing techniques for information inconsistencies detection mainly focus on stored information by using a single structured-fixed descriptive model which always requires support from sufficient prior knowledge. The aim of this study is to develop a method for information inconsistencies detection for real-time information in dynamic decision-making situation where prior knowledge is insufficient by using multiple descriptive models. First, a rule-map technique is presented. A rule-map is a hierarchical directed graph, whose vertexes are selected descriptive models and whose arcs represent the covering relationship between descriptive models. A rule-map provides a strategy for selecting detecting descriptive models by means of the covering relationship and its structure is adjustable with the change in a situation. Then, a real-time information inconsistencies detection method, named RMDID, is developed based on the rule-map technique, which can take full advantage of multiple descriptive models. Finally, the proposed RMDID method is tested through two real cases. Experiments indicate that the proposed rule-map technique can trace the changes of a dynamic decision-making situation and the developed RMDID method can efficiently detect potential anomalies in real-time information.

Abstract The North-Western Coast of Egypt (NWCE) represents one of the high priority regions for future development in the country. El-Hammam area is located in the NWCE with an area of 94752 acres and is one of the main challenging regions for sustaianble development. In this study, we have used remote sensing and soil data in combination with GIS tools, for land use sustainable analysis (SLU) in El-Hammam area. The SLU was established based on various factors such as: land capability and suitability, water resources availability, economic return from water and financial return from land and water. A physiographic soil map for the study area was prepared using remote sensing and GIS. Multiple field surveys were carried out for collecting information on various soil map units (SMUs) and their profiles. Laboratory analysis for the collected samples was performed, and then the soil properties were stored as attributes in a geographical soil database linked with the SMUs. Furthermore, land capability assessment was done to define the suitable areas for agricultural production using a capability model built in ALES software. Results indicate that the area currently lacks high capability and moderate capability classes. By improving the soil properties, the soil can attain potential capability; and 55630 acres will become marginally capable. The assessment of soil physical suitability for different land use types (LUTs) were analysed in ALES software, in order to generate the most suitable areas. The results from the land suitability analysis indicated that, 17114 acres are moderately suitable for wheat and sorghum; whereas 15823 acres are moderately suitable for barley and 12752 acres are moderately suitable for maize, olive and figs. Finally, the SLU was investigated based on two scenarios; (1) the most SLU under the conditions of shortage of irrigation water: clover, barley and sorghum against figs, as the irrigation ...

Abstract A study in modeling fire hazard assessment will be essential in establishing an effective forest fire management system especially in controlling and preventing peat fire. In this paper, we have used geographic information system (GIS), in combination with other geoinformation technologies such as remote sensing and computer modeling, for all aspects of wild land fire management. Identifying areas that have a high probability of burning is an important component of fire management planning. The development of spatially explicit GIS models has greatly facilitated this process by allowing managers to map and analyze variables contributing to fire occurrence across large, unique geographic units. Using the model and its associated software engine, the fire hazard map was produced. Extensive avenue programming scripts were written to provide additional capabilities in the development of these interfaces to meet the full complement of operational software considering various users requirements. The system developed not only possesses user friendly step by step operations to deliver the fire vulnerability mapping but also allows authorized users to edit, add or modify parameters whenever necessary. Results from the model can support fire hazard mapping in the forest and enhance alert system function by simulating and visualizing forest fire and helps for contingency planning.

This paper proposes a nonlinear generalization of the popular maximum-likelihood linear regression (MLLR) adaptation algorithm using kernel methods. The proposed method, called maximum penalized likelihood kernel regression adaptation (MPLKR), applies kernel regression with appropriate regularization to determine the affine model transform in a kernel-induced high-dimensional feature space. Although this is not the first attempt of applying kernel methods to conventional linear adaptation algorithms, unlike most of other kernelized adaptation methods such as kernel eigenvoice or kernel eigen-MLLR, MPLKR has the advantage that it is a convex optimization and its solution is always guaranteed to be globally optimal. In fact, the adapted Gaussian means can be obtained analytically by simply solving a system of linear equations. From the Bayesian perspective, MPLKR can also be considered as the kernel version of maximum a posteriori linear regression (MAPLR) adaptation. Supervised and unsupervised speaker adaptation using MPLKR were evaluated on the Resource Management and Wall Street Journal 5K tasks, respectively, achieving a word error rate reduction of 23.6% and 15.5% respectively over the speaker-independently model.

The longevity of compost-based storm water filtration systems has not been widely studied. Hydraulic conductivity measurements of compost amended sand media (20% and 50% v/v) within columns were undertaken. The results show that the filtration media in both columns had a reduction in the total saturated hydraulic conductivity. A tracer test showed there was no blockage due to biological or chemical fouling of the compost-sand (20% v/v) media. Particle size distributions results for the compost-sand (50% v/v) media suggest that there was minor degradation of compost particles. It appears gas production causing physical blockage was the most likely cause of the decline. It is recommended that compost filters are not run continuously but have drying periods which would allow any gas build-up to escape.

Tangible interaction is a growing area of human-computer interaction research that has become popular in recent years. Yet designers and researchers are still trying to comprehend and clarify its nature, characteristics, and implications. One approach has been to create frameworks that help us look back at and categorize past tangible interaction systems, and look forward at the possibilities and opportunities for developing new systems. To date, a number of different frameworks have been proposed that each provide different perspectives on the tangible interaction design space, and which can guide designers of new systems in different ways. In this paper, we map the space of tangible interaction frameworks.We order existing frameworks by their general type, and by the facets of tangible interaction design they address. One of our main conclusions is that most frameworks focus predominantly on the conceptual design of tangible systems, whereas fewer frameworks abstract the knowledge gained from previous systems, and hardly any framework provides concrete steps or tools for building new tangible systems. In addition, the facets most represented in existing frameworks are those that address the interactions with or the physicality of the designed systems. Other facets, such as domain-specific technology and experience, are rare. This focus on design, interaction, and physicality is interesting, as the origins of the field are rooted in engineering methods and have only recently started to incorporate more design-inspired approaches. As such, we expected more frameworks to focus on technologies and to provide concrete building suggestions for new tangible interaction systems.

Sequential batch leaching tests were used to evaluate the mass of DOC released from composted garden organics (yard waste), pine and hardwood under pseudo-equilibrium conditions. All media showed an initial rapid decline in DOC values followed by a slower rate during later time periods. Greater than 50% of the DOC leached occurred within the initial time period (<24 h). The mass of DOC leached varied significantly between the materials and to a lesser degree between different particle size ranges. The pine had the lowest leached DOC fraction (2.84.8 mg/g), while the hardwood (2127 mg/g) and compost (13.632.7 mg/g) were significantly greater. The type and processing of the woody material incorporated into these systems can have a significant impact on the treated stormwater.

The mechanisms and kinetics of dissolved organic carbon (DOC) release from woody materials (pine, hardwood and compost) under non-equilibrium leaching conditions was examined through batch and column tests. Mechanistically based kinetic models (first and second order) had a low predictive power for DOC release compared to those based solely on regression (Elovitch, power law). The DOC release data showed a bi-phasic response, with an early period of rapid release (<24 h) controlled by film diffusion followed by a slower rate controlled by intra-particle diffusion. After flow interruption, DOC release was primarily controlled by intra-particle diffusion; however, the specific rate parameters generally varied with each flow cycle and between different wood types.

We study different types of aggregation operators and the decision making process with minimization of regret. We analyze the original work developed by Savage and the recent work developed by Yager that generalizes the MMR method creating a parameterized family of minimal regret methods by using the ordered weighted averaging (OWA) operator. We suggest a new method that uses different types of geometric operators such as the weighted geometric mean or the ordered weighted geometric operator (OWG) to generalize the MMR method obtaining a new parameterized family of minimal regret methods. The main result obtained in this method is that it allows to aggregate negative numbers in the OWG operator. Finally, we give an illustrative example.

We introduce the use of the OWA operator in generalized distances such as the quasiarithmetic distance. We will call these new distance aggregation the ordered weighted quasi-arithmetic distance (Quasi-OWAD) operator. We develop a general overview of this type of generalization and study some of their main properties such as the distinction between descending and ascending orders. We also consider different families of Quasi-OWAD operators such as the Minkowski ordered weighted averaging distance (MOWAD) operator, the ordered weighted averaging distance (OWAD) operator, the Euclidean ordered weighted averaging distance (EOWAD) operator, the normalized quasi-arithmetic distance, etc.

Organ printing is a variant of the biomedical application of rapid prototyping technology or layer-by-layer additive biofabrication of 3D tissue and organ constructs using self-assembled tissue spheroids as building blocks. Bioengineering of perfusable intraorgan branched vascular trees incorporated into 3D tissue constructs is essential for the survival of bioprinted thick 3D tissues and organs. In order to design the optimal 'blueprint' for digital bioprinting of intraorgan branched vascular trees, the coefficients of tissue retraction associated with post-printing vascular tissue spheroid fusion and remodelling must be determined and incorporated into the original CAD. Using living tissue spheroids assembled into ring-like and tube-like vascular tissue constructs, the coefficient of tissue retraction has been experimentally evaluated. It has been shown that the internal diameter of ring-like and the height of tubular-like tissue constructs are significantly reduced during tissue spheroid fusion. During the tissue fusion process, the individual tissue spheroids also change their shape from ball-like to a conus-like form. A simple formula for the calculation of the necessary number of tissue spheroids for biofabrication of ring-like structures of desirable diameter has been deduced. These data provide sufficient information to design optimal CAD for bioprinted branched vascular trees of desirable final geometry and size.

Reinforced concrete (RC) structures in a chloride environment are exposed to a particularly aggressive form of deterioration. Managing the maintenance and repair of structures subjected to these conditions is an important issue facing asset owners and operators. In the present paper, the criterion for repair is the extent of corrosion induced cracking. Common maintenance criteria and maintenance techniques are described and these are incorporated into a two-dimensional spatial time-dependent reliability model. This allows the number, timing, and extent of maintenance actions to be predicted over the service life of RC structures. The analysis includes the effect of inspection interval, maintenance technique, repair efficiency, and repair threshold. Results are presented for a typical RC bridge deck subject to a corrosive marine environment. It was found that repair efficiency affecting time to corrosion initiation of repaired concrete is more critical to the performance of the repair than the repair efficiency that affected corrosion rate. © 2009 ASCE.

The study of Quality of Service (QoS) has become of great importance since the Internet is used to support a wide variety of new services and applications with its legacy structure. Current Internet architecture is based on the Best Effort (BE) model, which attempts to deliver all traffic as soon as possible within the limits of its abilities, but without any guarantee about throughput, delay, packet loss, etc. We develop a three-layer policy based architecture which can be deployed to control network resources intelligently and support QoS sensi-tive applications such as real-time voice and video streams along with standard applications in the Internet. In order to achieve selected QoS parameter values (e.g. loss, delay and PDV) within the bounds set through SLAs for high priority voice traffic in the Internet, we used traffic engineering techniques and policy based routing supported by Border Gateway Protocol (BGP). Use of prototype and simulations validates function-ality of our architecture

There are many computational techniques to model the consequences to built infrastructure when subject to explosive blast loads; however, the majority of these do not account for the uncertainties associated with system response or blast loading. This paper describes a new computational model, called “Blast-RF” (Blast Risks for Facades), that incorporates existing (deterministic) blast-response models within an environment that considers threat and (or) vulnerability uncertainties and variability using probability and structural reliability theory. The structural reliability analysis uses stress limit states and the UK Glazing Hazard Guide's rating criteria to calculate probabilities of glazing damage and occupant safety hazards conditional on a given blast scenario. This allows the prediction of likelihood and extent of damage and (or) casualties, useful information for risk mitigation considerations, emergency service's contingency and response planning, collateral damage estimation, weaponeering, and post-blast forensic analysis.

Although the modelling of built infrastructure subject to blast loading has been well developed, considerable uncertainty remains with respect to explosive loading parameters and structural response. This paper focuses on facade glazing - as this poses significant safety hazards when affected by explosive blast loads. A structural reliability analysis is used to calculate probabilities of glazing damage and safety hazards conditional on given threat scenarios. The analysis considers the variability of explosive blast loading; in particular, from variations in explosive weight, explosion effects in terms of pressure, stand-off distance, inherent blast load variability and model error. Uncertainties in structural response (including the variability in glazing stress limits, situational geometry, fragment drag coefficients and modelling error) are then considered in the analysis. This allows the prediction of likelihood and extent of damage and casualties. It was found that damage and safety hazard risks are very sensitive to the accuracy of the blast loading prediction model and the inherent variability of blast loading. © 2009 Elsevier Ltd.

This study aims at developing a modified green bioflocculant (GBF) for membrane fouling control and enhanced phosphorus removal in a conventional aerated submerged membrane bioreactor (SMBR) to treat a high strength domestic wastewater (primary sewage treated effluent) for reuse. The GBF was evaluated based on long-term operation of a lab-scale SMBR. These results showed that SMBR system could achieve nearly zero membrane fouling at a very low dose of GBF addition (500 mg/day) with less backwash frequency (2 times/day with 2-min duration). The transmembrane pressure only increased by 2.5 kPa after 70 days of operation. The SMBR could also remove more than 95% and 99.5% dissolved organic carbon and total phosphorus, respectively. From the respiration tests, it was evident that GBF not only had no negative impact on biomass but also led to high oxygen uptake rate (OUR) (>30 mg O2/L h) and stable specific oxygen uptake rate (SOUR). These results also indicated that GBF had no effect on nitrogen removal and nitrification process.

The concept of using recycled water for washing machine was introduced as a new end use. As there is a noticeable lack social research in understanding the general public perceptions of this application, the residents strategy survey was carried out at some selective suburbs in Sydney with demographically based signifi cant differences of general, gender, age, education, and property style and ownership. The survey indicates that the majority in the community considers the use of recycled water for washing machine is indispensable in view of continuing drought and the associated water shortages. Given safety assurance and demonstration, recycled water for washing machine has a considerable proportion within the responses. The general level of knowledge in community clearly understand that recycled water is more environmentally friendly option, whereas from cleanness and public health point of view, higher quality water is required to be reused in washing machine. Moreover, the residents reckon to have a small unit for pre-treatment (point of use) before recycled water entering washing machines might assure the quality and safety. The survey also shows the major concerns for a resident to use recycled water for washing machine are public health, water cleanness and washing machine durability.

Objective: Widespread application of early goal-directed therapy (EGDT) and the severe sepsis resuscitation bundle is limited by clinician knowledge, skills and experience. This study evaluated use of simulation-based teaching during medical training to increase future clinician knowledge in the above therapies for severe sepsis and septic shock. Methods: A prospective cohort study was performed with medical students at all levels of training. A 5-h course including didactic lectures, skill workshops, and a simulated case scenario of septic shock were administered to the participants. A checklist including 21 tasks was completed during the patient simulation. An 18-question pre-test, post-test and 2-week post-test were given. The participants completed a survey at the end of the course. Results: Sixty-three students were enrolled. There was statistical difference between the pre-test and each of the post-test scores: 57.5 ± 13.0, 85.6 ± 8.8, and 80.9 ± 10.9%, respectively. 20.6% of participants thought the pre-test was too difficult, whereas all participants thought the post-test was either appropriate or too easy. The task performance during the simulated septic shock patient was 94.1 ± 6.0%. The participants noted improvements in their confidence levels at managing severe sepsis and septic shock, and agreed that the course should be a requirement during medical school training. Conclusions: Medical simulation is an effective method of educating EGDT and the severe sepsis resuscitation bundle to medical students with limited experience in patient care. The results suggest that our course may be of further benefit at increasing clinical experience with this intensive protocol for the management of severe sepsis and septic shock. © 2009 Elsevier Ireland Ltd.

The main purpose of this article is to explore the relationship of two existing conditions for the triangular decoupling problem. The first one is the triangular-diagonal-dominance condition proposed by Hung and Anderson. The second one is the stable coprime factorisation-described condition proposed by Gomez and Goodwin, which has been proven as a necessary and sufficient condition for the triangular decoupling problem. This article proves that the two conditions are actually equivalent. It also provides easy-to-use criteria for assessment of the solvability of the triangular decoupling problem.

This cross-sectional study showed that peak bone mineral density in Vietnamese women is comparable to that in Caucasian women; however, the prevalence of osteoporosis in post-menopausal Vietnamese women was slightly higher than in Caucasian women. The age of achieving peak bone mass in Vietnamese women was between 26 and 30 years. Introduction: While peak bone mass and its determinants have been well-documented in Caucasian populations, little has been studied in Asian populations. The present study was designed to estimate the peak bone mineral density (BMD), age of its attainment, and to examine the prevalence of osteoporosis in Vietnamese women aged 50+. Methods: The study was designed as a cross-sectional study with 328 women aged between 10 and 65 years (average age: 41) who were randomly selected from two districts around Hanoi city according to a stratified sampling scheme. BMD at the lumbar spine, femoral neck and total hip was measured by a DXA instrument (GE Lunar Prodigy, WI, USA). BMD was modeled as a cubic function of age, from which peak BMD and age at peak BMD were estimated. Bootstrap method was utilized to estimate the 95% confidence interval of peak BMD and age at peak BMD. From the peak BMD, T-score was calculated for each woman, and using the World Health Organization criteria, any woman with femoral neck BMD T-score ≤ -2.5 was classified as having osteoporosis. Results: Peak BMD was estimated at 1.16 g/cm2 (standard deviation [SD]: 0.13 g/cm2) at the lumbar spine, 1.02 g/cm2 (SD 0.12) at the total hip, and 0.94 g/cm 2 (SD 0.11) at the femoral neck. In the cubic polynomial model, the age at peak BMD was estimated to range between 27 and 29 years. The prevalence of osteoporosis among those aged between 50 and 65 years was 23%. This prevalence was higher than in Chinese, Japanese, Korean and Caucasian populations. Conclusion: These data suggest that although the peak BMD in Vietnamese women is comparable to, the prevalence of osteoporosis is hig...

Background: Despite massive efforts, progress so far has been modest in isolating the genetic determinants for intracranial aneurysm (IA). More detailed epidemiology data might be essential for successful genome-wide association study. Here, we aimed to investigate epidemiology and identify the key risk factors associated with the pathogenesis of IA in a large specific population. Methods: We investigated the epidemiology and analyzed the risk factors of IA pathogenesis by using an International Classification of Diseases, Ninth Revision database search of the patients treated at the University of Mississippi Medical Center, Jackson, MS, within the past 10-year period (1998-2007). All recruited patients were interviewed to assess multiple risk factors and comorbidities (hypertension, tobacco abuse, females sex, diabetes mellitus, coronary artery disease, coronary obstructive pulmonary disease, alcohol abuse, stroke, hyperlipidemia, illicit drug use, and family history). Result: In this retrospective study, we identified several significant risk factors among well-defined human subjects. The 3 major risk factors identified for our IA population are hypertension, tobacco abuse, and female sex. However, African American race was not a significant risk factor in our study. Furthermore, top two risk factors (hypertension, tobacco abuse) were found to be highly associated with familial cases. Conclusions: In this study, using a specific and well-defined large population, we reported that some key risk factors were further confirmed to be strongly associated with the pathogenesis of IA whereas further investigation into racial factors is apparently needed. Our finding of the confounding effects of top risks with familial cases further complicated the genetic analysis of IA.

There is a global need to develop low-cost technologies to remove arsenic from water for individual household water supply. In this study, a purified and enriched waste material (treated magnetite waste, TMW) from the Trai Cau's iron ore mine in the Thai Nguyen Province in Vietnam was examined for its capacity to remove arsenic. The treatment system was packed with TMW that consisted of 75% of ferrous-ferric oxide (Fe3O4) and had a large surface area of 89.7m2/g. The experiments were conducted at a filtration rate of 0.05 m/h to treat groundwater with an arsenic concentration of 380 μg/L and iron, manganese and phosphate concentrations of 2.07 mg/L, 0.093 mg/L and 1.6 mg/L respectively. The batch experimental results show that this new material was able to absorb up to 0.74mg arsenic/g. The results also indicated that the treatment system removed more than 90% arsenic giving an effluent with an arsenic concentration of less than 30 μg/L while achieving a removal efficiency of about 80% for Mn2+ and PO43-. This could be a promising and cost-effective new material for capturing arsenic as well as other metals from groundwater. © IWA Publishing 2009.

One of the problems in drinking water that raises concern over the world is that millions of people still have to use arsenic-contaminated water. There is a worldwide need to develop appropriate technologies to remove arsenic from water for household and community water supply systems. In this study, a new material namely iron oxide coated sponge (IOCSp) was developed and used to remove arsenic (As) from contaminated groundwater in Vietnam. The results indicated that lOCSp has a high capacity in removing both As (V) and As (III). The adsorption capacity of IOCSp was up to 4.6 mg As/g IOCSp, showing better than many other materials. It was observed from a pilot study that a small quantity of IOCSp (180 g) could reduce As concentration of 480 μg/L in 1.5 m3 of contaminated natural water to below 40 μg/L. In addition, an exhausted IOCSp, containing a large amount of arsenic (up to 0.42 wt %) could safely be disposed through the solidification/stabilization with cement. Addition of fly ash also reduced the amount of arsenic in the leachate. © IWA Publishing 2009.

Arsenic is a toxic semi-metallic element that can be fatal to human health. Membrane filtration can remove a number of contaminants from water, including arsenic. Removal of arsenic by membrane filtration is highly dependent on the species of arsenic and the properties of the membrane. The performance of the nanofilter is better for removing As(V) than As(III). About 57% of As(III) and 81% of As(V) was removed from 500 mg/L arsenic solutions by nanofiltration (NTR729HF, Nitto Denko Corp., Japan) of 700 molecular weight (MW) cutoff. The removal efficiency of microfiltration (MF) was much lower than that of nanofiltration (NF) due to its larger pore size. By comparison only 37% of As(III) and 40% of As(V) were removed by microfiltration (PVA membrane, Pure-Envitech, Korea). However, the removal efficiency of microfiltration was increased dramatically when a small amount of nanoscale zero valent iron (nZVI) was added. The removal efficiency by MF increased up to 90% with As(V) and 84% with As(III) when an amount of 0.1 g/L of nZVI was added into the arsenic solution.

AbstractA bioenergetic methodology was integrated with a modified activated sludge model No.1 (ASM1) to analyze the activated sludge process, with the treatment of soybean‐processing wastewater as an example. With the bioenergetic methodology established by McCarty and coworkers, the microbial yield was predicted and the overall stoichiometrics for biological reactions involving the key chemical and biological species in activated sludge were established. These obtained parameters were related to the ASM1 model, which was modified after coupling the biological reactions in activated sludge with electron balances. This approach was able to approximately describe the treatment of soybean wastewater by activated sludge in a sequencing batch reactor in terms of substrate utilization, biomass growth, and the elector acceptor consumption. Such an attempt provides useful information for accurate modeling of the complex activated sludge process. © 2009 American Institute of Chemical Engineers AIChE J, 2009

AbstractIn this work, we attempted to modify the Activated Sludge Model No.3 and to simulate the performance of a full‐scale sequencing batch reactor (SBR) plant for municipal wastewater treatment. The long‐term dynamic data from the continuous operation of this SBR plant were simulated. The influent wastewater composition was characterized using batch measurements. After incorporating all the relevant processes, the sensitivity of the stoichiometric and kinetic coefficients for the model was thoroughly analyzed prior to the model calibration. The modified model was calibrated and validated with the data from both batch‐ and full‐scale experiments. Model predictions were compared with routine data in terms of chemical oxygen demand, NH4+‐N and mixed liquid volatile suspended solids in the SBR, combined with batch experimental data under different conditions. The model predictions match the experimental results well, demonstrating that the model is appropriate to simulate the performance of a full‐scale wastewater treatment plant even operated under perturbation conditions. © 2009 American Institute of Chemical Engineers AIChE J, 2009

Cell immobilized lipase-producing bacteria on three different matrices were incorporated in a fat-, oil-, and grease (FOG) trap system for restaurant wastewater treatment. During a 16-day laboratory-scale experiment for the treatment of synthetic FOG wastewater containing soybean oil, no significant difference (two-tailed t test at 95% confidence interval) in the FOG removal between two systems was observed at FOG influent < 1,000 mg/L. However, the typical trap showed lower FOG removal efficiency than the matrix-based system when the influent FOG concentration was increased to >= 5,000 mg/L. In addition, the matrix-based trap system was able to sustain a stable high FOG removal, with < 100 mg/L effluent, even at 10,000 mg/L influent FOG. Based on FOG heights measured and mass balance calculations, 97.4 and 99.5% of the total FOG load for 16 days were removed in a typical trap and matrix-based system, respectively. About 93.6% of the removal in the matrix-based was accounted to biodegradation. The 30-day full-scale operations demonstrated a distinguishably better performance in the matrix-based system (92.7 +/- 9.06% of 1,044.8 +/- 537.27 mg FOG/L) than in the typical trap system (74.6 +/- 27.13% of 463.4 +/- 296.87 mg FOG/L) for the treatment of barbeque restaurant wastewater. Similarly, matrix-based system revealed higher chemical oxygen demand removal (85.9 +/- 11.99%) than the typical trap system (60.4 +/- 31.26%). Characterizations of the influent, emulsified, adsorbed and effluent FOG indicated that straight saturated fatty acids constituted the cause of clogging problems in the FOG-trap and piping system.

In this study, titanium tetrachloride (TiCl4), titanium sulfate (Ti(SO4)2) and ferric chloride (FeCl3) flocculation as a pretreatment to seawater reverse osmosis (SWRO) were investigated. Their ability to remove turbidity, seawater organic matter (SWOM) and controlling the feed water quality of SWRO was evaluated. Flux decline of SWRO and membrane autopsy were studied. Titanium dioxide (TiO2) produced from sludge after Ti-salt fl occulation was characterized in terms of particle structure and photocatalytic activity. A hybrid system of fl occulation followed by granular activated carbon (GAC) filtration was employed to remove the suspended micro-flocs after diff erent fl occulations. The optimum dose of 10 mg/L TiCl4 and FeCl3 were used. The turbidity removal for the three coagulants was marginal at different doses at pH 6 and 8. Flocculation followed by GAC fi ltration signifi cantly reduced the turbidity values from 1.5 NTU to about 0.35 NTU using TiCl4 and 0.40 using FeCl3. Silt density index (SDI15) was also decreased from 5.0 to 4.2 and 4.7, respectively. Removal of dissolved organic carbon (DOC), colour and UV absorbance after TiCl4 and FeCl3 flocculation followed by GAC fi ltration was found to be eff ective and similar. TiO2 produced from sludge showed very high photocatalytic activity under UV-irradiation. Acetaldehyde was completely removed after 45 min photocatalytic reaction

Flocculation with titanium tetrachloride (TiCl4) and titanium sulfate (Ti(SO4)2) was investigated in terms of different coagulant doses, pH, turbidity, dissolved organic carbon (DOC), UV-254, colour, zeta potential, particle size and molecular weight distribution. The two coagulants were compared with the commonly used coagulants such as ferric chloride (FeCl3) and aluminium sulfate (Al2(SO4)3). Titanium tetrachloride showed the highest turbidity removal, while titanium sulfate showed the highest reduction of UV-254 and colour at all pH values. The four coagulants were found to have similar organic removal up to 6067% and resulted in similar organic removal in terms of various MW ranges. The decantability of the settled flocs was very high for titanium tetrachloride, titanium sulfate and ferric chloride compared with aluminium sulfate. The dominating coagulation mechanisms for titanium tetrachloride and titanium sulfate are still to be studied, since different precipitation reactions might take place at different pH even without flocculant addition. Titanium tetrachloride and titanium sulfate were found as effective new coagulants in wastewater treatment not only in terms of organic matter removal, but also in sludge reduction through the production of titanium dioxide.

An infilled rock joint is likely to be the weakest plane in a rock mass. The presence of infill material within the joint significantly reduces the friction of the discontinuity boundaries (i.e. rock to rock contact of the joint walls). The thicker the infill, the smaller the shear strength of the rock joint. Once the infill reaches a critical thickness, the infill material governs the overall shear strength, and the joint walls (rock) play no significant role. Several models have been proposed to predict the peak shear strength of soil-infilled joints under both constant normal load (CNL) and constant normal stiffness (CNS) boundary conditions, taking into account the ratio of infill thickness (t) to the height of the joint wall asperity (a). CNS models provide a more realistic picture of the soil-infilled joint behaviour in the field. This paper presents a critical review on the existing mathematical models for predicting the shear strength of soil-infilled rock joint and verifies the normalised peak shear stress model with further laboratory investigations carried out on idealised saw-tooth rock joints at the University of Wollongong. Based on the prediction of the experimental data, the normalised peak shear stress model is slightly modified by the authors. A simplified approach for using this model in practice is presented and a new expression for prediction of dilatation at peak shear stress is suggested.

RNA-mediated gene silencing, in the form of RNA interference (RNAi) or microRNAs (miRNAs) has provided novel tools for gene discovery and validation in mammalian cells. Here, we report on the construction and application of a random small RNA expression library for use in identifying small interfering RNA (siRNA) effectors that can modify complex cellular phenotypes in mammalian cells. The library is based in a retroviral vector and uses convergent promoters to produce unique small complementary RNAs. Using this library, we identify a range of small RNA-encoding gene inserts that overcome resistance to 5-fluorouracil (5-FU)- or tumour necrosis factor alpha (TNF-a)- induced cell death in colorectal cancer cells. We demonstrate the utility of this technology platform by identifying a key RNA effector, in the form of a siRNA, which overcomes cell death induced by the chemotherapeutic 5-FU. The technology described has the potential to identify both functional RNA modulators capable of altering physiological systems and the cellular target genes altered by these modulators.

View description>>

Many real-life applications often involve multiple sequences, which are coupled with each other. It is unreasonable to either study the multiple coupled sequences separately or simply merge them into one sequence, because the information about their interacting relationships would be lost. Furthermore, such coupled sequences also have frequently significant changes which are likely to degrade the performance of trained model. Taking the detection of abnormal trading activity patterns in stock markets as an example, this paper proposes a Hidden Markov Model-based approach to address the above two issues. Our approach is suitable for sequence analysis on multiple coupled sequences and can adapt to the significant sequence changes automatically. Substantial experiments conducted on a real dataset show that our approach is effective.

The probability hypothesis density (PHD) filter is an attractive approach to tracking an unknown and time-varying number of targets in the presence of data association uncertainty, clutter, noise, and detection uncertainty. The PHD filter admits a closed-form solution for a linear Gaussian multi-target model. However, this model is not general enough to accommodate maneuvering targets that switch between several models. In this paper, we generalize the notion of linear jump Markov systems to the multiple target case to accommodate births, deaths, and switching dynamics. We then derive a closed-form solution to the PHD recursion for the proposed linear Gaussian jump Markov multi-target model. Based on this an efficient method for tracking multiple maneuvering targets that switch between a set of linear Gaussian models is developed. An analytic implementation of the PHD filter using statistical linear regression technique is also proposed for targets that switch between a set of nonlinear models. We demonstrate through simulations that the proposed PHD filters are effective in tracking multiple maneuvering targets.

In this paper, we propose an optimization method based on Particle Swarm Optimization (PSO) algorithm for thinning a large multiple concentric circular ring array of uniformly excited isotropic antennas and generate a pencil beam in the vertical plane with minimum relative side lobe level (SLL). The half-power beam width of the pattern is attempted to make equal to that of a fully populated array of same size and shape. The synthesis is performed with a standard particle swarm optimization technique as well as with an improved version of standard PSO. Simulation results of the proposed thinned array are compared with a fully populated array to illustrate the effectiveness of our proposed method. © 2009 Springer Science+Business Media, LLC.

This paper presents an integrated exploration approach for geometric mapping and surface material-type identification of complex three-dimensional (3D) environments using a six-degree-of-freedom industrial robot manipulator. Maps of the surface geometry with the surface material type identified are required for an autonomous robotic system to perform operations in steel bridge maintenance. The proposed approach utilizes information theory to enable multiobjective exploration while new 3D geometric and surface-type data are fused via probabilistic updates. It is verified that the integrated approach enables the robotic system to perform exploration and surface inspection in real-world environments. © 2009 Wiley Periodicals, Inc.

This paper describes a simultaneous localization and mapping (SLAM) algorithm for use in unstructured environments that is effective regardless of the geometric complexity of the environment. Features are described using B-splines as modeling tool, and the set of control points defining their shape is used to form a complete and compact description of the environment, thus making it feasible to use an extended Kalman-filter (EKF) based SLAM algorithm. This method is the first known EKF-SLAM implementation capable of describing general free-form features in a parametric manner. Efficient strategies for computing the relevant Jacobians, perform data association, initialization, and map enlargement are presented. The algorithms are evaluated for accuracy and consistency using computer simulations, and for effectiveness using experimental data gathered from different real environments.

This paper presents the conceptual model of a survey and knowledge translation methodology to enable the assessment of the implementation of technology in neonatal intensive care units (NICUs) in order to determine the impact of information technology (IT) on information flows and patient care. Survey data, will be completed by healthcare practitioners from multiple roles, for various patient care scenarios, levels of care, and hospitals, and will then be translated using a structured data modelling approach into patient journey models. The data model is defined such that users can develop queries to generate patient journey models based on a pre-defined Patient Journey Model Architecture (PaJMa). PaJMa models will then be analyzed to build a visual representation of information flows and the use of IT in the NICU. The models will offer a sophisticated view of health informatics usage, providing not only details of what IT solutions a hospital utilizes, but also the impact that the IT solutions have when integrated into the patient journey, how they support the patient information flow, and why they improve the patient journey. © 2009 Springer-Verlag Berlin Heidelberg.

Kurzfassung Produzierende Unternehmen müssen sich auf wettbewerbsorientierten Märkten behaupten, die sich durch eine starke Preiskonkurrenz sowie kurze Produktlebenszyklen auszeichnen. Um die eigene Marktposition zu festigen oder vielmehr zu verbessern, müssen Produktions-, Konstruktions- sowie Planungsprozesse optimal aufeinander abgestimmt sein. Die Feature-Technologie bietet in diesem Zusammenhang neue Möglichkeiten, um die Prozesse der Produktentstehung und den Informationsfluss zwischen den beteiligten Planungsbereichen zu verbessern. Die Feature-Technologie wird hierbei genutzt, um die individuellen und spezifischen Anforderungen, die sich in den verschiedenen Bereichen der Produktionsplanung an das Produkt ergeben, in standardisierter Form zu dokumentieren und an die Konstruktion zu übertragen. Auf diese Weise können Produktänderungen gezielt und mit allen Planern abgestimmt durchgeführt werden. Folglich lassen sich aufwändige Iterationsschleifen zwischen Konstruktion und Planung vermeiden.

This paper investigates the ‘effective life’ (or useful lifespan) of permeable pavement installations subject to sediment loadings. The broad aims of this study, which included both laboratory and field work components, were to improve understanding of the long-term pavement hydraulic conductivity, to assess the effective life of permeable pavements and to quantify the degree of sediment trapping and associated pollutant retention. Three types of permeable pavement were investigated. For each type the effects of pavement cleaning were also investigated. Over a simulated 35 years of sediment loading conducted in the laboratory, the results showed reductions of 59–75% in hydraulic conductivity with an average sediment retention of 94%. Suspended sediment concentrations measured at the outflow of the laboratory test beds did not show any significant difference between pavers that were subjected to cleaning and those that were not. For the field studies presented in this paper, hydraulic conductivities were very high in locations where permeable pavements are subjected to small to moderate sediment loads. At other locations with high coarse sediment and organic sediment loads, hydraulic conductivity tests indicated that clogging occurred at a rapid rate, particularly where runoff flowing onto the pavement was concentrated.

Methods The study included all 510 communes of the Central Highlands region (with a total population of similar to 4 million) where 95% of incidence of plague cases in Vietnam had been reported from 1997 through 2002. Plague was clinically ascertained by using a standard protocol by WHO. Data on domestic fleas and rodents were obtained by using traps and periodic surveillance in accordance with the WHO guidelines. Temperature, duration of sunshine, rainfall and humidity were recorded as monthly averages by local meteorological stations. The association between these ecological factors and plague was assessed by using the Poisson regression model. Results From 1997 through 2002, 472 cases of plague were reported, of whom 24 (5.1%) died. The incidence of plague peaked during the dry season, with similar to 63% of cases occurring from February through April. The risk of plague occurrence was associated with an increased monthly flea index (RR and 95% CI: 1.93; 1.61-2.33 for months with the flea index > 1) and increased rodent density (RR 1.23; 1.15-1.32 per each 3% increase in density). Moreover, the risk of plague increased during the dry season (RR 2.07; 1.64-2.62), when rainfall fell < 10 mm (RR 1.44; 1.17-1.77). Conclusions These data suggest that the flea index, rodent density and rainfall could be used as ecological indicators of plague risk in Vietnam. The data also suggest that the occurrence of plague in Vietnam's Central Highlands is likely resulted from multiple causes that remain to be delineated.

Vector quantization is a useful approach for multi-dimensional data compression and pattern classification. One of the most popular techniques for vector quantization design is the LBG (Linde, Buzo, Gray) algorithm. To address the problem of producing poor estimate of vector centroids which are subjected to biased data in vector quantization; we propose a fuzzy declustering strategy for the LBG algorithm. The proposed technique calculates appropriate declustering weights to adjust the global data distribution. Using the result of fuzzy declustering-based vector quantization design, we incorporate the notion of fuzzy partition entropy into the distortion measures that can be useful for classification of spectral features. Experimental results obtained from simulated and real data sets demonstrate the effective performance of the proposed approach. © 2009 Elsevier Ltd. All rights reserved.

This paper addresses the design of H ? state feedback controllers for a class of nonlinear time-varying delay systems. The interesting features here are that the system in consideration is nonautonomous with fast-varying delays, the delay is also involved in the observation output, and the controllers to be designed satisfy some exponential stability constraints on the closed-loop poles. By using the proposed Lyapunov functional approach, neither a controllability assumption nor a bound restriction on nonlinear perturbations is required to obtain new sufficient conditions for the H ? control. The conditions are derived in terms of a solution to the standard Riccati differential equations, which allows for simultaneous computation of the two bounds that characterize the stability rate of the solution.

In this paper, we propose a new peak to average power ratio (PAPR) reduction technique by a hybrid algorithm based on a partial transmit sequence (PTS) and adaptive peak power reduction (APPR) methods. This technique is used in a system based on orthogonal frequency division multiplexing (OFDM OFDM has orthogonally modulated sub-carriers which unexpectedly give large PAPR and tends to reduce the power efficiency of a RF amplifier. To reduce PAPR, the sequence of input data is rearranged by PTS for the reduction of PAPR and then fed to APPR process in the proposed system. The APPR method controls the peak level of the modulation signal by an adaptive algorithm. It reduces modulation signals over a predefined range. A proposed reduction method consists of these two methods and realizes both advantages at the same time. In simulation results, the proposed method shows the improvement on PAPR, PSD, and also the high performance on bit error rate of an OFDM system.

Recently, in the year 2006, 2007 and 2008 heavy monsoons rainfall have triggered floods along Malaysia's east coast as well as in different parts of the country. The hardest hit areas are along the east coast of peninsular Malaysia in the states of Kelantan, Terengganu and Pahang. The flood cost nearly millions of dollars of property and many lives. Foods are considered to be one of the weather-related natural disasters. Many methods exist to provide qualitative estimations of the risk level of flood susceptibility mapping within a watershed. This paper presents construction of a flood susceptible map for presumptive flood areas around at Kelantan river basin in Malaysia using a statistical model and GIS. To evaluate the factors related to flood susceptible analysis, a spatial database was constructed from a topographical map, geological map, hydrological map, Global Positioning System (GPS) data, land cover map, digital elevation model (DEM) data, and precipitation data. An attribute database was also constructed from field investigations and historical flood areas reports for the study area. Logistic regression model was applied to determine each factor's rating, and the ratings were overlaid for flood susceptibility mapping. Results indicate that flood prone areas can be performed at 1:25,000 which is comparable to some conventional flood hazard map scales. The flood prone areas delineated on these maps correspond to areas that would be inundated by significant flooding. Further, risk analysis has been performed using DEM, distance from hazard zone, land cover map and damageable objects at risk. DEM was used to delineate the catchments and served as a mask to extract the highest hazard zones of the landslide area. Qualitatively, the model seems to give reasonable results with accuracy observed was 85%.

AbstractThis paper summarizes the findings of groundwater potential zonation mapping at the Bharangi River basin, Thane district, Maharastra, India, using Satty’s Analytical Hierarchal Process model with the aid of GIS tools and remote sensing data. To meet the objectives, remotely sensed data were used in extracting lineaments, faults and drainage pattern which influence the groundwater sources to the aquifer. The digitally processed satellite images were subsequently combined in a GIS with ancillary data such as topographical (slope, drainage), geological (litho types and lineaments), hydrogeomorphology and constructed into a spatial database using GIS and image processing tools. In this study, six thematic layers were used for groundwater potential analysis. Each thematic layer’s weight was determined, and groundwater potential indices were calculated using groundwater conditions. The present study has demonstrated the capabilities of remote sensing and GIS techniques in the demarcation of different groundwater potential zones for hard rock basaltic basin.

This paper presents landslide hazard and risk analysis using remote sensing data, GIS tools and artificial neural network model. Landslide locations were identified in the study area from interpretation of aerial photographs and from field surveys. Topographical and geological data and satellite images were collected, processed, and constructed into a spatial database using GIS and image processing. These factors were used with artificial neural network to analyze landslide hazard. Each factor's weight was determined by the back-propagation training method. Then the landslide hazard indices were calculated using the trained back-propagation weights, and the landslide hazard map was created using GIS tools. Landslide locations were used to verify results of the landslide hazard maps and to compare them. The results of the analysis were verified using the landslide location data and compared with neural network model with all cases. The accuracy observed was 83, 72, 82, 79 and 81% for training sites 1, 2, 3, 4 and 5 respectively. GIS data was used to efficiently analyze the large volume of data, and the artificial neural network proved to be an effective tool for landslide hazard analysis. Further, risk analysis has been performed using DEM, distance from hazard zone, land cover map and damageable objects at risk. DEM was used to delineate the catchments and served as a mask to extract the highest hazard zones of the landslide area. Risk map was produced using map overlying techniques in GIS. This information could be used to estimate the risk to population, property and existing infrastructure like transportation network. © 2009 Academic Journals.

This paper summarizes the findings of the maximum flood prone area mapping at Kelantan river basin, Malaysia, using multiple logistic regression model with the aid of GIS tools and remote sensing data. To map the maximum flood prone areas, at first the flood extent areas were extracted from RADARSAT 1 images and supported with ground data, existing reports and field notes. To evaluate the factors associated with flood prone areas, a spatial database was constructed from a topographical map, geological map, hydrological map, Global Positioning System (GPS) data, land cover map, SPOT 5 satellite image, digital elevation model (DEM), and precipitation data. Nine major parameters were extracted for the logistic regression analysis to determine each factor's rating, and the ratings were computed for flood prone area mapping analysis. Results indicate that flood prone area mapping which can be termed as susceptibility map can be performed at 1:25,000 which is comparable to some conventional medium scaled flood hazard map. The flood prone areas delineated on these map correspond to areas that would be inundated by significant flooding (approximately the 100 year flood).

This article presents analytical formulas for determining mode I and II energy release rates for two cases: (a) cohesive fracture of adhesive joints and; (b) interlaminar delamination of layered beams. The formulas are firstly derived for calculating energy release rates GI and GII for a crack propagating in adhesive layer from one crack tip by using a classical beam-adhesive model. Then novel and simple closed-form formulas of G I and GII for an interface crack in layered beams are obtained by letting the adhesive thickness approach zero. In the present formulas, the effects of the asymmetry and each force component are clearly identified.

This article presents constitutive models for photo-induced strains in photostrictive materials and an optimal design of microcantilevers driven by light illumination. Behaviors of photo-induced strains in semiconductors and polymeric materials are reviewed first, and then new phenomenological constitutive models are developed that depict two distinctive features of photo-induced strain profile: (a) dependence on variation of light intensity which decreases with the depth measured from the illuminated surface due to light attenuation and energy absorption; and (b) anisotropy or dependence on direction of light polarization. On the basis of the constitutive modeling of photo-induced strain in wafers, design optimization of microcantilevers is then investigated for both geometrically linear and non-linear deformations.

An accurate means of determining bone age is a goal for forensic scientists. In this study, thermogravimetric analysis (TGA) has been used to examine pig bone specimens of different post-mortem age. Analysis of bone in both air and nitrogen atmospheres reveals a decrease in total mass loss as the bones age. Two mass loss steps due to the decomposition of the organic bone components were observed and show decreasing trends with age for decomposition in an air atmosphere. In a nitrogen atmosphere the decomposition was observed to be more complex and age dependence of the mass loss for each step was not identified. The TGA data, however, demonstrates the potential of the technique as a means of estimating post-mortem age of forensic bone specimens.

View description>>

Acidic groundwater, generated from acid sulphate soil (ASS), is a major geo-environmental problem in Australia. Manipulation of groundwater through the use of weirs and gates in the nearby creeks and drains of ASS, which is being practised right now for preventing pyrite oxidation, is not effective in low land floodplains due to the risk of flooding. The application of a permeable reactive barrier (PRB) can be an alternative for remediation of acidic groundwater in such floodplains. Laboratory column experiments were carried out prior to installation of the PRB for examining the efficiency of the material. Results of these experiments have shown that recycled concrete could effectively neutralise the acidic water for longer periods with complete removal of aluminium (Al) and iron (Fe). Despite the reduction of the efficiency of the recycled concrete due to armouring by accumulated precipitates of Al and Fe, excellent performance was observed for an extended period under controlled laboratory condition. Following these results, a pilot PRB was installed in the Broughton Creek flood plains in southeast NSW to observe its performance under varying natural conditions of the field. The PRB has been maintaining near neutral pH with complete removal of Al and Fe from the groundwater of ASS matching with the results of column test. The promising performance of the pilot PRB for the last three years shows that PRB can be used as one of the cost effective and environmental friendly alternative to other recently utilised techniques in ASS.

A UASB reactor was visualized as being set‐up of a number of continuously stirred tank reactors (CSTRs) in series. An increasing‐sized CSTRs (ISC) model was developed to describe the hydrodynamics of such a bioreactor. The gradually increasing tank size in the ISC model implies that the dispersion coefficient decreased along the axial of the UASB reactor and that its hydrodynamic behavior was basically dispersion‐controlled. Experimental results from both laboratory‐scale H2‐producing and full‐scale CH4‐producing UASB reactors were used to validate this model. Simulation results demonstrate that the ISC model was better than the other models in describing the hydrodynamics of the UASB reactors. Moreover, a three‐dimensional computational fluid dynamics (CFD) simulation was performed with an Eulerian‐Eulerian three‐phase‐fluid approach to visualize the phase holdup and to explore the flow patterns in UASB reactors. The results from the CFD simulation were comparable with those of the ISC model predictions in terms of the flow patterns and dead zone fractions. The simulation results about the flow field further confirm the discontinuity in the mixing behaviors throughout a UASB reactor. © 2008 American Institute of Chemical Engineers AIChE J, 2009

Electroencephalography (EEG) can be used as an indicator of fatigue. Several studies have shown that slow wave brain activities, delta (0-4 Hz) and theta (4- 8 Hz), increase as an individual becomes fatigued, while the fast brain activities, alpha (8-13 Hz) and beta (13-35 Hz), decrease. However, an EEG is a complex piece of equipment that is generally used in laboratory based studies. In order to develop a fatigue countermeasure device for train drivers using EEG, there is a need for a simple and wireless EEG monitor. This paper explains the development of a single channel wireless EEG device.

A system of vertical drains with surcharge preloading is an effective method for promoting radial drainage and accelerated soil consolidation. This study presents a procedure for the design of vertical drains that significantly extends the previous technique proposed by the authors to include: (i) a linear reduction of lateral permeability in the smear zone, (ii) the effect of overlapping smear zones in a closely spaced drain network, and (iii) the gain in undrained shear strength due to consolidation. Design examples are provided for both single stage and multi-stage embankment construction demonstrating the convenient use of the proposed solutions in practical situations.

This paper presents initial results from electrical, spectroscopic and ion beam induced charge (IBIC) characterisation of a novel silicon PIN detector, featuring an on-chip n -channel JFET and matched feedback capacitor integrated on its p-side (frontside). This structure reduces electronic noise by minimising stray capacitance and enables highly efficient optical coupling between the detector back-side and scintillator, providing a fill factor of close to 100%. The detector is specifically designed for use in high resolution gamma cameras, where a pixellated scintillator crystal is directly coupled to an array of silicon photodetectors. The on-chip JFET is matched with the photodiode capacitance and forms the input stage of an external charge sensitive preamplifier (CSA). The integrated monolithic feedback capacitor eliminates the need for an external feedback capacitor in the external electronic readout circuit, improving the system performance by eliminating uncontrolled parasitic capacitances. An optimised noise figure of 152 electrons RMS was obtained with a shaping time of 2 mus and a total detector capacitance of 2 pF. The energy resolution obtained at room temperature (2degC) at 27 keV (direct interaction of I-125 gamma rays) was 5.09%, measured at full width at half maximum (FWHM). The effectiveness of the guard ring in minimising the detector leakage current and its influence on the total charge collection volume is clearly demonstrated by the IBIC images.

AbstractIn this paper we propose an energy‐efficient self‐organizing global extremity reporting scheme for wireless sensor networks. The proposed scheme assists applications of periodic reporting of extreme values (such as maximum or minimum temperature/pressure) across a wireless sensor field, back to the sink. Furthermore, an event‐driven counterpart is supplied for individual sensor nodes to supply their instantaneous sensed values back to the sink, once queried. The targeted sensors initially establish their relative distances to the sink in regards to number of hops, whilst the highest hopcount nodes (HHNs) from the sink identify themselves. The broadcast initiation of the HHNs have the ability to penetrate all nodes within the network towards the sink, and hence obtain the extreme value of the entire network in an efficient manner. This is due to the relative position of these special nodes within the network. Furthermore, the scheme does not require nodes to possess location information of themselves or other nodes, avoiding the need for the global positioning system (GPS) or other location‐aware methods. Simulation results show the effectiveness of the proposed protocol in its target application. In particular, the advantage of HHN‐initiated broadcasting can be seen in both uniformly and randomly distributed topology networks. Copyright © 2008 John Wiley & Sons, Ltd.

Naturally occurring elevated levels of nitrates are detected in many of the groundwater bores in the arid zone of Central Australia. Such levels are associated with anemia in young babies, pregnant women and other vulnerable groups. Further, there is evidence that links long-term exposure to elevated levels of nitrates with gastric cancer. In many parts of arid Central Australia alternative sources of water are not available. The capacity to operate and maintain water treatment and supply systems in remote Indigenous communities varies due to access and levels of service provision, mobility of the residents and balance of skills within the communities. A need has thus been identifi ed for a low maintenance nitrate removal system. Conventional treatment processes do not remove nitrates. Alternatives, such as reverse osmosis, ion exchange or biological denitrifi cation are either complex, energy and water intensive, expensive, produce waste products requiring disposal or require continual maintenance and monitoring. Such preconditions are not able to be met in remote Indigenous communities. This paper reviews the problems of nitrates in the arid zone of Central Australia and explores existing technologies for their removal, relative to remote Indigenous settings. It identifi es a need for further investigations to tailor technology to the unique social, economic and cultural characteristics of these settings.

Purpose - The purpose of this paper is to analyse the importance and role of process knowledge in the business process (BP) improvement methodology with the help of a case study. Design/methodology/approach - The approach takes the form of a literature review that highlights the challenges and issues in the existing BP improvement methodologies. An in-depth case study that has embarked on a major BP improvement initiative that emphasizes individual and collective process knowledge in a real-life complex organization is presented. Findings - The paper confirms that BP improvement is, in fact, a complex, knowledge-intensive, collaborative process that consists of a set of coordinated, contextualized knowledge management processes. The design of the "to-be" process in this study is a knowledge co-creation process that uses collaborative exploration of different scenarios and contexts. Compared with the traditional BP improvement methodologies where the main emphasis is on the design of a new process model, the focus of the methodology employed in this case study is on the process of knowledge co-creation and transfer. Research limitations/implications - The paper leads to increased recognition of the knowledge and experience people develop, use and share while modeling, executing, and improving their BPs. It offers anecdotal evidence and general case study research limitations apply. Practical implications - Practitioners should focus more on key knowledge processes rather than BP models that often obscure the role of individual and collective process knowledge. Rather than investing limited resources in the mapping and modeling of existing processes, practitioners will be able to better serve their organizations if they concentrate on the improvement of the process by tapping the contextualized process knowledge possessed by the individual actors. Originality/value - In the expanding field of BP management, the study explores the increasing importance of individual...

In this paper, we consider a network of energy constrained sensors deployed over a region. Each sensor node in such a network is systematically gathering and transmitting sensed data to a base station (via clusterheads). This paper focuses on reducing the power consumption of wireless sensor networks. We first extend LEACH's stochastic clusterhead selection algorithm by an average energy-based (LEACH-AE) deterministic component to reduce energy consumption. And then an unequal clustering idea is introduced to further reduce energy consumption of clusterheads. Simulation results show that our modified scheme can extend the network life by up to 38% before the first node dies in the network. Through both theoretical analysis and numerical results, it is shown that the proposed algorithm achieves better performance than the existing clustering algorithms such as LEACH, DCHS, LEACH-C.

View description>>

A distributed energy-efficient unequal clustering (DEEUC) algorithm was proposed for wireless sensor networks by research current routing algorithms. The core of DEEUC has three parts. Firstly, when tentative clusterheads are selected, an average energy factor was introduced to balance the residual energy of the whole network nodes so that it may improve the network energy efficiency. Secondly, an energy consumption ratio function was proposed to balance energy-efficient of each node. Finally, an unequal clustering algorithm was proposed for single-hop homogeneous networks. Through both theoretical analysis and numerical results, it is shown that DEEUC prolongs the network lifetime significantly against the other clustering protocols such as LEACH-C and EECS. Under general instance, DEEUC may prolong the lifetime up to 30% against EECS.

OBJECTIVE:: To define a biomarker panel to predict organ dysfunction, shock, and in-hospital mortality in emergency department (ED) patients with suspected sepsis. DESIGN:: Prospective observational study. SETTING:: EDs of ten academic medical centers. PATIENTS:: There were 971 patients enrolled. Inclusion criteria: 1) ED patients age > 18; 2) suspected infection or a serum lactate level > 2.5 mmol/L; and 3) two or more systemic inflammatory response syndrome criteria. Exclusion criteria: pregnancy, do-not-resuscitate status, or cardiac arrest. MEASUREMENTS AND MAIN RESULTS:: Nine biomarkers were assayed from blood draws obtained on ED presentation. Multivariable logistic regression was used to identify an optimal combination of biomarkers to create a panel. The derived formula for weighting biomarker values was used to calculate a "sepsis score," which was the predicted probability of the primary outcome of severe sepsis (sepsis plus organ dysfunction) within 72 hrs. We also assessed the ability of the sepsis score to predict secondary outcome measures of septic shock within 72 hrs and in-hospital mortality. The overall rates of each outcome were severe sepsis, 52%; septic shock, 39%; and in-hospital mortality 7%. Among the nine biomarkers tested, the optimal 3-marker panel was neutrophil gelatinase-associated lipocalin, protein C, and interleukin-1 receptor antagonist. The area under the curve for the accuracy of the sepsis score derived from these three biomarkers was 0.80 for severe sepsis, 0.77 for septic shock, and 0.79 for death. When included in multivariate models with clinical variables, the sepsis score remained highly significant (p < 0.001) for all the three outcomes. CONCLUSIONS:: A biomarker panel of neutrophil gelatinase-associated lipocalin, interleukin-1ra, and Protein C was predictive of severe sepsis, septic shock, and death in ED patients with suspected sepsis. Further study is warranted to prospectively validate the clinical utility of these...

Geometric dilution of precision (GDOP) has been widely used as an accuracy metric for navigation and tracking systems. Since high accuracy in a positioning system requires both accurate measurement of the range and a good geometric relationship between the mobile device and the measuring points, the analysis of GDOP is an essential feature in determining the performance of a positioning system. In this paper, we perform GDOP analysis to obtain concise analytical expressions for a number of scenarios, which are generally applicable to geometries where the mobile device is surrounded by base stations. Comparison of the analytical results with simulations using the typical geometries of indoor positioning systems shows good agreement, except when the mobile position is close to a base station. This effect is a consequence of the ranging errors being a significant proportion of the range in short-range tracking systems and discontinuities in GDOP at the base station. The results provide useful information for the design and testing of tracking systems, as well as for the determination of the geometric deployment of base stations for good GDOP in the coverage area. © 2009 IEEE.

The performance of the peak and leading edge detection methods for time-of-arrival (TOA) estimation in band-limited systems is examined. Analytical expressions for the detection performance in the presence of both random noise and multipath interference are derived. A dimensionless performance factor is presented that allows simple comparisons of the TOA estimation algorithms. These equations allow the performance tradeoff analysis to be undertaken without the need for simulations. It is shown that the leading edge detection method has significantly better multipath mitigation characteristics than the peak detection one, but at the expense of inferior noise performance. © 2009, The Institution of Engineering and Technology.

We examine theoretic architectures and an abstract model for a restricted class of quantum computation, called here temporally unstructured (`instantaneous) quantum computation because it allows for essentially no temporal structure within the quantum dynamics. Using the theory of binary matroids, we argue that the paradigm is rich enough to enable sampling from probability distributions that cannot, classically, be sampled efficiently and accurately. This paradigm also admits simple interactive proof games that may convince a sceptic of the existence of truly quantum effects. Furthermore, these effects can be created using significantly fewer qubits than are required for running Shors algorithm.

During the past few years, titanium salts were investigated as alternative coagulants for the removal of organic matter of different molecular sizes in contaminated water. The flocculation efficiency of Ti-salt was comparable to those of FeCl3 and Al2(SO4)3 salts, commonly used coagulants. Incinerated sludge-TiO2 showed higher surface area and photocatalytic activity than commercially available TiO2. Metal-doped forms were produced by adding coagulant aids such as iron (Fe-), aluminium (Al-) and (Ca-) calcium salts during Ti-salt flocculation to increase pH. Ca- and Al- doped TiO2 showed very high photocatalytic activity compared to Fe-doped TiO2. When tested in a pilot scale plant for treatment of dye wastewater to check practical feasibility of the novel process, the removal ratio of the chemical oxygen demand was comparable to those of commonly used coagulants but the settling of sludge was faster. The TiO2 generated after sludge incineration showed a high photocatalytic activity for degradation of volatile organic compounds and increased the rate of hydrogen production by water photosplitting. TiCl4 coagulant and TiO2 produced from different water sources with different concentrations had low acute toxicity compared to heavy metals and commercial TiO2 when examined based on D. Magna mortality. This paper presents the production, characterisation and the photoactivity of TiO2 produced from Ti-salt flocculated sludge. Different case studies are discussed to highlighted recent advances in this field.

A simple and novel method to synthesize iron and aluminium-doped titanium dioxide (TiO2) was investigated. Titanium tetrachloride (TiCl4) was used as a coagulant to remove organic matter from wastewater. The settled floc (sludge) was dewatered and incinerated at 600 degrees C after TiCl4 flocculation. The resultant by-product from the waste sludge was valuable TiO2. TiCl4 coagulant was added with FeCl3 and Al-2(SO4)(3) coagulants to dope iron and aluminium on TiO2 in a flocculation process. The effect of iron and aluminium on TiO2 was investigated in terms of scanning electron microscopy/energy dispersive Xray (SEM/EDX), X-ray diffraction (XRD), optical absorbance and photocatalytic activity. The majority of Fe/TiO2 and Al/TiO2 particles were found to be less than 1 mu m size formed by 0.1 mu m agglomerates using SEM analysis. Fe/TiO2 included Ti, O, C, P and Fe elements and Al/TiO2 consisted of Ti, O, C, P and Al elements as confirmed by EDX results. Remaining organic carbon from the settled organic matter was the source of C atom in TiO2 whereas the P atom in TiO2 came from phosphorus nutrient present in wastewater. The majority of acetaldehyde with Fe/TiO2 and AI/TiO2 was significantly removed under UV irradiation within 60 min. However, at higher iron concentration, acetaldehyde removal decreased by almost 50%. Under visible light irradiation, the photo-decomposition of acetaldehyde using the Fe/TiO2 and Al/TiO2 was marginal.

The pretreatment of raw seawater is necessary to minimize the organic fouling of seawater reverse osmosis (SWRO) membranes. To predict the membrane fouling of the pretreated seawater, the modified fouling index (MFI) with ultrafiltration (UF) was investigated in terms of molecular weight distribution (MWD) and membrane characterization. The study was conducted with seawater drawn from Collioure, France. The concentration of total dissolved solids was 32,760 mg/L. The molecular weight (MW) of the initial seawater organic matter (SWOM) ranged from about 14160 Da to 280 Da. FeCl3 flocculation removed the majority of SWOM, while PAC adsorption could not remove the lowest MW fraction of organic matter (1110, 750 and 280 Da). The UF membranes with 30 kDa and 100 kDa MW cut-off removed the majority of of organic matter corresponding to the peaks 14,160 Da and 6560 Da in MWD. The MFI values obtained when using UF membranes of 30 kDa and 100 kDa with MF pretreatment were 19,700 s/L2 and 31,000 s/L2, respectively. The MFI values after pretreatments of FeCl3 flocculation and PAC adsorption significantly decreased to 6900 s/L2 and 6700 for 30 kDa UF and to 2300 s/L2 and 2500 s/L2 for 100 kDa UF, respectively. Some relation does exist for both membranes between the MFIUF values and Spb values obtained during the first peiod of filtration (pore blocking). The pore blocking zone significantly decreased after flocculation and adsorption pretreatment. This suggests that the pore blocking can be used as an indicator to predict membrane propensity. The detailed membrane characterization on the clean and fouled membrane surface after MFIUF experiments was made in terms of contact angle, zeta potential, functional group and microscopy.

Although membrane technology has become a reliable and viable alternative for water and wastewater treatment, membrane fouling is a serious challenge. In this case study, we report application of different techniques to extract foulant from the hollow fibre membrane and char-acterize the foulant into various components of organic, inorganic and different fractions. The organic foulant was subjected to high-pressure size exclusion chromatography (HPSEC) and flow field-flow fractionation (FlFFF) analysis to study the influence of ionic strength on its elution behaviour using NaCl and CaCl2 as carrier solutions. It was observed that an increase in ionic strength delayed the elution time of both the organic foulant and the Na-salt of Polysterene sulphone (PSS) with HPSEC. However, no such effect was observed with FlFFF analysis. Such study is significant because the characteristics of the membrane organic foulant are believed to be influenced by the carrier ionic conditions and pH and, therefore their subsequent interaction with the membrane and membrane fouling process. However with FlFFF, whether the influence of carrier ionic strength is limited to certain type of ionic carriers or certain groups of natural organic matter is a scope for further research. © 2009 Desalination Publications.

In this study, the settled floc (sludge) produced by aluminum sulfate (Al2(SO4)3), ferric chloride (FeCl3) and titanium tetrachloride (TiCl4) flocculation was recycled with a novel flocculation process, which has a significant potential to the lower cost of waste disposal, protect the environment and public health and yield economically useful by-products. Three coagulants removed 70% of organic matter in synthetic wastewater. The settled floc was incinerated in the range from 100 8C to 1000 8C. Alumina (Al2O3), hematite (Fe2O3), titanium oxide (TiO2) which are the most widely used metal oxides were produced from the wastewater sludge generated by the flocculation in wastewater with Al2(SO4)3, FeCl3 and TiCl4, respectively. TiO2 particles produced from the sludge consisted of the large amount of nano size particles. Hematite (Fe2O3) and grattarolaite (Fe3 (PO4)O3 or Fe3PO7) included the majority of micro size (40%) particles. Alumina (Al2O3) also consisted of micro size (40%). Due to TiO2 usefulness of the application, detailed characterisation of TiO2 after calcination at different temperatures were investigated in terms of X-ray diffraction, energy dispersive X-ray, surface area and photoactivity.

In this study, TiCl4 coagulant together with coagulant aids such as FeCl3, Al2(SO4)3, and Ca(OH)2 were investigated to improve the photoactivity of titanium dioxide (TiO2) produced from sludge and to increase the resulting low pH value. After TiCl4 flocculation with three coagulant aids, the settled floc (sludge) was incinerated at 600°C to produce TiO2 doped with Fe, Al, and Ca elements. Fe-, Al-, and Ca-doped TiO2 was characterized in terms of structural, chemical, and photo-electronic properties. All the coagulant aids used together with Ti-salt flocculation effectively increased the pH values. The surface area of TiO2-WO (without any coagulant aids), Fe/TiO2, Al/TiO2, and Ca/TiO2 was 122 m2/g, 77 m2/g, 136 m2/g and 116 m2/g, respectively. The TiO2-WO, Fe/TiO2, Al/TiO2, and Ca/TiO2 was found to be of anatase phase. The XRD pattern on the Fe/TiO2 included an additional peak of hematite (α-Fe2O3). The majority of gaseous acetaldehyde with TiO2-WO and Ca/TiO2 for photocatalytic activity was completely removed within 40 minutes under UV irradiation.

In this study, different pretreatment methods such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), powdered activated carbon (PAC) adsorption and ferric chloride (FeCl3) flocculation were evaluated in terms of their capability in removing seawater organic matter (SWOM) and the characteristics of the foulants on the seawater reverse osmosis (SWRO) membranes. A detailed experiment with a crossflow SWRO filtration unit was conducted with SR membrane (MWCO 100 Da) at 60 bar with seawater (conductivity = 48.9 mS/cm) drawn from south-western Korea. The SWOM removal by UF, NF, PAC adsorption and FeCl3 flocculation was 20.3, 28.9, 46 and 23.3%, respectively. SWOM used in this study predominantly consisted of small size organic matter (<1000 Da). A large amount of the hydrophobic fraction present in SWOM was removed by PAC adsorption. The SDI5min significantly decreased from 12.7 (without any pretreatment) to 3.2 (MF), 1.3 (UF), 1.0 (NF) and 4.4 (PAC adsorption). RO filtration of seawater with and without pretreatment showed significant flux decline (normalized flux decline (J/J0) = 0.17 ± 0.02) within 20-h operation. The elemental analyses made on the RO surface after direct RO filtration showed that the relative fraction of the carbon decreased, while sodium (Na), magnesium (Mg), chlorine (Cl) and iron (Fe) elements were found in the foulants extracted from the fouled membrane surface. The average roughness of the clean membrane surface was 41.5 nm. After MF and UF pretreatment, the roughness slightly increased to 54.8 and 55.6 nm, respectively. On the other hand, without any pretreatment, with PAC adsorption and with FeCl3 flocculation, the roughness increased up to 69.7, 66.4 and 110 nm, respectively. It can be concluded that the pretreatment by MF and UF could relatively preserve the RO membrane surface.

Reinforced concrete connections, designed prior to the implementation of earthquake design standards, may be vulnerable to shear failure during a seismic attack. Addition of externally bonded fibre-reinforced polymer (FRP) composites can enhance not just the shear capacity but the deformation and energy absorption capacity of the connection. The majority of research studies to date have opted for complete or nearcomplete coverage of the joint region with FRP and have subjected the test specimens to cyclic (push-pull) loading. Such strengthening schemes and method of loading make it quite difficult to accurately monitor and hence understand the behaviour of the FRP and the concrete beneath. This paper presents results of a series of tests on the strengthening of shear deficient connections with FRP strips subjected to either cyclic or monotonic loading with the primary motivation being accurate description of the behaviour of the FRP. The tests also enable the failure modes to be more accurately reported and classified especially due to the use of monotonic loading. An analytical model is finally presented which accurately describes the mechanics of the FRP strengthening with the model predictions correlating reasonably well with the test data.

AbstractSeveral real‐world applications require mining of bicliques, as they represent correlated pairs of data clusters. However, the mining quality is adversely affected by missing and noisy data. Moreover, some applications only require strong interactions between data members of the pairs, but bicliques are pairs that display complete interactions. We address these two limitations by proposing maximal quasi‐bicliques. Maximal quasi‐bicliques tolerate erroneous and missing data, and also relax the interactions between the data members of their pairs. Besides, maximal quasi‐bicliques do not suffer from skewed distribution of missing edges that prior quasi‐bicliques have. We develop an algorithm MQBminer, which mines the complete set of maximal quasi‐bicliques from either bipartite or non‐bipartite graphs. We demonstrate the versatility and effectiveness of maximal quasi‐bicliques to discover highly correlated pairs of data in two diverse real‐world datasets. First, we propose to solve a novel financial stocks analysis problem using maximal quasi‐bicliques to co‐cluster stocks and financial ratios. Results show that the stocks in our co‐clusters usually have significant correlations in their price performance. Second, we use maximal quasi‐bicliques on a mining protein network problem and we show that pairs of protein groups mined by maximal quasi‐bicliques are more significant than those mined by maximal bicliques.

Water Sensitive Urban Design (WSUD) is something of a catch-all term for environmentally sustainable water resource management in urban areas. Water sensitive urban design offers an alternative to the traditional conveyance approach to stormwater management. It seeks to minimise the extent of impervious surfaces and mitigate changes to the natural water balance, through on-site reuse of water as well as through temporary storage. By integrating major and minor fl ow paths in the landscape and adopting a range of water sensitive design techniques, the size of the structural stormwater system required can be signifi cantly reduced. WSUD techniques include detention and retention basins to lower peak fl ows, grassed swales and vegetation to facilitate water infi ltration and pollutant fi ltration. WSUD has been adopted widely in Australia and is being implemented in varied local government areas. The major challenge to the success of WSUD is however its measure of effectiveness over the life cycle given that it demands high maintenance. The aim of this paper is to provide a snapshot of effectiveness of WSUD implemented in Kogarah Municipal Council using two case studies and presents results on improvement in water quality through both site specifi c and water quality monitoring of the bays.

Kurzfassung Die Einführung eines schlanken Produktionssystems zur Produktivitätssteigerung in einem Wertstrom führt in der Organisation eines Betriebs und in den Arbeitsaufgaben der Mitarbeiter zu großen Veränderungen. Für das übergeordnete Verständnis und die Akzeptanz dieser Veränderungen sind alle Mitarbeiter in integrierten Schulungsmaßnahmen vorzubereiten und zu qualifizieren. In der primären Schulung werden Prinzipen und Methoden des Produktionssystems zusammenhängend erläutert. Darauf aufbauend können vertiefende Schulungen durchgeführt werden. Da neben der rein fachlichen Wissensvermittlung auch eine positive Erwartungshaltung gegenüber dem Produktionssystem erreicht werden soll, können traditionelle Schulungsmethoden ohne didaktische Hilfsmittel diese Anforderungen nicht mehr erfüllen. Das Planspiel erweist sich im Vergleich zu anderen didaktischen Instrumenten für diese Anforderungen als geeignete Ergänzung. Es integriert handlungsorientierte Ansätze, zielgruppenspezifische Unterstützung und die Möglichkeit einer umfassenden Verdeutlichung von Zusammenhängen und deren Auswirkungen.

A spatial time-dependent reliability model is developed for a RC beam subject to corrosion-induced pitting corrosion, for shear and flexural limit states. The analysis considers the spatial and time-dependent variability of pitting corrosion, structural resistance and load effects. The amount of corrosion loss can significantly affect the mechanical behaviour of reinforcement, namely low corrosion loss can result in ductile yielding, whereas a higher corrosion loss can result in brittle fracture. The progression from ductile to brittle behaviour is spatially and time-dependent. To estimate how such phenomena affects structural reliability the structural resistance of reinforcement is modelled as either (i) perfectly ductile parallel system or (ii) perfectly brittle parallel system. It was found that the probability of failure assuming brittle reinforcement behaviour is up to 450% higher than assuming ductile behaviour. © 2008 Elsevier Ltd. All rights reserved.

A spatial time-dependent reliability model is developed for a RC beam subject to corrosion-induced pitting corrosion. The analysis considers the spatial and time-dependent variability of pitting corrosion and its effect on cover cracking and shear and flexural resistance. The model uses extreme value theory to predict maximum pit depth as a function of bar diameter and reinforcing bar length. The effect of corrosion on the mechanical behaviour of reinforcement and associated loss of ductility is also considered. A 1D spatial model is included where concrete properties, concrete cover and the surface chloride concentration are treated as random fields. The model is then used to predict the likelihood and extent of corrosion-induced cracking (corrosion damage). The spatial time-dependent reliability model allows the loss of structural capacity and reliability to be calculated conditional to the observed extent of corrosion damage. This allows the interaction between corrosion damage and loss of structural safety to be inferred for a deteriorating RC beam. It was found that the crack width at time of structural collapse is often well in excess of 1 mm. It was also found that the extent and location of severe cover cracking is an important indicator of structural reliability. © 2008 Elsevier Ltd. All rights reserved.

The main motivation of this study is to establish an ambulatory cardio-respiratory analysis system for the monitoring and evaluation of exercise and regular daily physical activity. We explored the estimation of oxygen uptake by using noninvasive portable sensors. These sensors are easy to use but may suffer from malfunctions under free living environments. A promising solution is to combine sensors with different measuring mechanisms to improve both reliability and accuracy of the estimation results. For this purpose, we selected a wireless heart rate sensor and a tri-axial accelerometer to form a complementary sensor platform. We analyzed the relationship between oxygen uptake measured by gas analysis and data collected from the simple portable sensors using multivariable nonlinear modeling approaches. It was observed that the resulting nonlinear multivariable model could not only achieve a better estimate compared with single input single output models, but also had greater potential to improve reliability.

It is well known that the corrosion-induced cracking of reinforced concrete (RC) structures varies in time and space due to the inherent spatial variability of concrete cover, concrete strength, surface chloride concentration and other material, environmental and dimensional properties. A model for predicting the likelihood and extent of RC corrosion-induced cracking considering spatial variability is reviewed. The uncertainties of predictions can be reduced by the effective use of information obtained from visual inspections regarding structural performance, such as cracking proportion and crack width. The paper uses a spatial time-dependent reliability analysis combined with visual inspection data to predict the likelihood and extent of RC corrosion-induced cracking. In this study, RC slabs and beams are used to illustrate the influence of inspection information updating on the future likelihood and extent of corrosion-induced cracking. Concrete strength, concrete cover and the surface chloride concentrations are modelled as spatial variables. Monte-Carlo simulation is employed to calculate the updated cracking proportions. The analysis considers various inspection scenarios which include different inspection intervals, inspection times, cracking proportion and crack width. It was found that the occurrence or observance of cracking changes the future cracking prediction significantly. © 2009 Elsevier Ltd. All rights reserved.

It has been recently recognized that aggregated traffic in a variety of networks exhibits a similar impulsiveness over a wide range of aggregation levels, but approaches a Gaussian distribution in the limit as the aggregation level grows. Although several traffic models have been proposed in the past decade, their accuracy in simultaneously characterizing the above properties still needs to be further improved. In this letter, we propose a truncated α-stable process model which is able to capture the impulsiveness of observed network traffic as well as its tendency toward the Gaussian distribution with aggregation. An inherent physical mechanism is also proposed to give insight into the underlying meaning of the proposed model. Simulation results show that the proposed process achieves close agreement with real traffic and outperforms previous models. © 2006 IEEE.

Rhabdomyosarcoma (RMS) is a childhood cancer originating from skeletal muscle, and patient survival is poor in the presence of metastatic disease. Few determinants that regulate metastasis development have been identified. The receptor tyrosine kinase FGFR4 is highly expressed in RMS tissue, suggesting a role in tumorigenesis, although its functional importance has not been defined. Here, we report the identification of mutations in FGFR4 in human RMS tumors that lead to its activation and present evidence that it functions as an oncogene in RMS. Higher FGFR4 expression in RMS tumors was associated with advanced-stage cancer and poor survival, while FGFR4 knockdown in a human RMS cell line reduced tumor growth and experimental lung metastases when the cells were transplanted into mice. Moreover, 6 FGFR4 tyrosine kinase domain mutations were found among 7 of 94 (7.5%) primary human RMS tumors. The mutants K535 and E550 increased autophosphorylation, Stat3 signaling, tumor proliferation, and metastatic potential when expressed in a murine RMS cell line. These mutants also transformed NIH 3T3 cells and led to an enhanced metastatic phenotype. Finally, murine RMS cell lines expressing the K535 and E550 FGFR4 mutants were substantially more susceptible to apoptosis in the presence of a pharmacologic FGFR inhibitor than the control cell lines expressing the empty vector or wild-type FGFR4. Together, our results demonstrate that mutationally activated FGFR4 acts as an oncogene, and these are what we believe to be the first known mutations in a receptor tyrosine kinase in RMS. These findings support the potential therapeutic targeting of FGFR4 in RMS.

In many applications, convection heat transfer is coupled with conduction and radiation heat transfer, which generate temperature gradients along the walls and may greatly affect natural convection heat transfer. The main objective of this study is to calculate the heat-transfer characteristics for natural convection from a non-isothermal vertical flat plate into a supercritical fluid. The influence of the non-uniformity of wall temperature on the heat transfer by natural convection along a vertical plate, having a linearly distributed temperature (characterized by the slope S) is also investigated. The thermal expansion coefficient is considered as a function of the temperature, the pressure, the van der Waals constants and the compressibility factor. The trends of the curves obtained with this equation and with values from tables of thermodynamic properties were similar and diverged at a critical point. These features confirmed the validity of this equation. Then, the governing systems of partial differential equations are solved numerically using the finite difference method. The local Nusselt number was then calculated and plotted as a function of the local Rayleigh number. It was observed that a positive slope of temperature distribution increases the heat transfer rate and a negative slope decreases it. © Sharif University of Technology, December 2009.

Due to the difficulties of outlier and skewed data, the prediction of breast cancer survivability has presented many challenges in the field of data mining and pattern precognition, especially in medical research. To solve these problems, we have proposed a hybrid approach to generating higher quality data sets in the creation of improved breast cancer survival prediction models. This approach comprises two main steps: (1) utilization of an outlier filtering approach based on C-Support Vector Classification (C-SVC) to identify and eliminate outlier instances; and (2) application of an over-sampling approach using over-sampling with replacement to increase the number of instances in the minority class. In order to assess the capability and effectiveness of the proposed approach, several measurement methods including basic performance (e.g., accuracy, sensitivity, and specificity), Area Under the receiver operating characteristic Curve (AUC) and F-measure were utilized. Moreover, a 10-fold cross-validation method was used to reduce the bias and variance of the results of breast cancer survivability prediction models. Results have indicated that the proposed approach leads to improving the performance of breast cancer survivability prediction models by up to 28.34% due to the improved training data space.

We present results of a new process for generating 1/f type noise sequences and introducing the noise in the primary visual cortex which then enables improved perception of weak edges when an observer is scanning a complex image in real time to detect detail such as in mammogram reading sessions. It can be explained by an adaptation of information theory for functional rather than previous task-based methods for formulating processes for edge formation in early vision. This is enabled from a two "species" classification of the interaction of opposing on-centre and off-centre neuron processes. We show that non-stationary stochastic resonances predicted by theory can occur with 1/f noise in the primary visual cortex VI and suggest that signalling exchanges between VI and the lateral geniculate nucleus (LGN) of the thalamus can initiate neural activity for saccadic action (and observer attention) for weak edge perception. Improvements predicted by our theory were shown from 600 observations by two groups of observers of limited experience and an experienced radiologist for reference (but not for diagnosis). They scanned and rated the definition of microcalcification in clusters separately rated by the experienced radiologist. The results and supporting theory showed dependence on the observer's attention and orderly scanning. Using a compact simplified equipment configuration the methodology has important clinical applications for conjunction searches of features and for detection of objects in poor light conditions for vehicles.

A new problem is addressed, which is how to improve energy efficiency for both unicast and multicast services without violating QoS requirements of mobile stations in 802.16e wireless networks. To solve this problem, a scheduling set based integrated scheduling (SSBIS) algorithm is proposed. SSBIS partitions all the mobile stations into multicast scheduling sets and a unicast scheduling set. All the unicast data of the mobile stations in the multicast scheduling sets are transmitted in the adjacent intervals of their multicast data transmission periods, and for the mobile stations in the unicast scheduling set, longest sleep duration based (LSDB) scheduling scheme is obtained using convex optimization to improve energy efficiency of the whole system. Numerical results show that SSBIS can save overall energy significantly and guarantee the minimum data rates of mobile stations at the same time. © 2008 by Journal of Software.

In classical and quantum information theory, operational quantities such as the amount of randomness that can be extracted from a given source or the amount of space needed to store given data are normally characterized by one of two entropy measures, called smooth min-entropy and smooth max-entropy, respectively. While both entropies are equal to the von Neumann entropy in certain special cases (e.g., asymptotically, for many independent repetitions of the given data), their values can differ arbitrarily in the general case. In this work, a recently discovered duality relation between (non-smooth) min- and max-entropies is extended to the smooth case. More precisely, it is shown that the smooth min-entropy of a system A conditioned on a system B equals the negative of the smooth max-entropy of A conditioned on a purifying system C. This result immediately implies that certain operational quantities (such as the amount of compression and the amount of randomness that can be extracted from given data) are related. Such relations may, for example, have applications in cryptographic security proofs.

Among many biometric characteristics, the facial biometric is considered to be the least intrusive technology that can be deployed in the real-world visual surveillance environment. However, in facial biometric, little research attention has been paid to facial expression changes. In fact, facial expression changes have often been treated as noise that would degrade the recognition performance. This paper studies an innovative viewpoint: (1) whether facial expression changes, namely facial behavior, can be positively used for face recognition or not? (2) furthermore, can facial behavior be integrated with facial appearance for assisting the extra-personal separation to enhance face recognition performance? We propose a bi-modal face recognition framework which integrates facial expression with facial appearance. Substantial experiments on multiple facial appearance and facial expression data have been conducted. Our experimental results have validated that facial behavior can play a positive role in face recognition and can assist facial appearance in extra-personal separation in multiple modalities for personal identification improvement.

The main emphasis is made on modelling deterioration due to corrosion of reinforcing steel. A critical overview of existing models for corrosion initiation, corrosion-induced cracking, and effects of corrosion on deflections and strength of reinforced concrete (RC) structures is presented, including discussion of future research needs. Recent accomplishments of the authors in this area are described. Special attention is paid to the role of spatial variability of deterioration on results of reliability assessment, which is illustrated by two examples.

In the paper corrosion-induced crack initiation and propagation are investigated experimentally and numerically, with particular emphasis on quantifying the proportion of corrosion products that are dissipated within the concrete pores and cracks, thus reducing the pressure exerted by corrosion products on the surrounding concrete. Initially, experimental data on crack initiation and propagation obtained from accelerated corrosion tests of reinforced concrete slabs are presented. A comparison of finite-element model results and experimental data is used to estimate the amount of corrosion products penetrating into concrete pores and cracks, which is an essential parameter for prediction of corrosion initiation and propagation. It was found that the amount of corrosion products penetrating into the concrete pores before crack initiation is larger than that obtained by other researchers. The paper also showed that corrosion products do not fully fill corrosion-induced cracks in concrete immediately after their initiation as the cracks are being filled gradually over time and the thicker the concrete cover the longer it will take to fully fill a crack. © 2009 ASCE.

When meeting someone new, the first impression is often influenced by someoneâs physical appearance and other types of prejudice. In this paper, we present TouchMeDare, an interactive canvas, which aims to provide an experience when meeting new people, while preventing visual prejudice and lowering potential thresholds. The focus of the designed experience was to stimulate people to get acquainted through the interactive canvas. TouchMeDare consists of a flexible, opaque canvas, which plays music when touched simultaneously from both sides. Dynamic variation of this bodily contact is reflected through real-time adaptations of the musical compositions. Two redesigns were qualitatively and quantitatively evaluated and a final version was placed in the Lowlands Festival as a case study. Evaluation results showed that some explanation was needed for the initial interaction with the installation. On the other hand, after this initial unfamiliarity passed, results showed that making bodily contact through the installation did help people to get acquainted with each other and increased their social interaction.

Global warming presents an ever-challenging battle to humankind, as emissions arising from industrially produced gteenhouse gases are predicted to alter the long-term climatic patterns of earth. Harmful environmental emissions arising during the manufactute of Portland cements (C) can be effectively reduced by incorporating siliceous-aluminous based supplementary cementitious materials (SCMs), as partial cement replacements. In Australia, mined pitchstone fines (PF), derived as waste material from expandable perlire production, area viable SCM for reducing cement consumption using an eco-friendly approach. This paper reports on the results of an experimental investigation into the pozzolanic activity of PP. Up to 40% cement was replaced with PF in mortar mixes. In addition, PP was used to partially replace sand. Strength activity index (SM) values for PP were evaluated using accelerated 28-day compressive strengths for all PP substitution levels, with flows and wet densities of mortar mixes reported.

Thermogravimetric (TG) analysis was applied to the characterisation of the pozzolanic reaction in mortars containing the supplementary cementitious materials (SCMs) pitchstone fines (PF) and fly ash (FA) as partial replacements for Portland cement (PC). TG analysis was used to determine the proportion of calcium hydroxide (CH) present from the hydration of the PC based on the dehydroxylation of the CH present in the blended PC-SCM mortars. The consumption of CH indicated that both SCMs underwent the pozzolanic reaction and that PF was found to compare favourably in its pozzolanic reactivity of FA, the industry and globally accepted standard artificial pozzolan.

Abstract.  Since the middle of the twentieth century, the problem of making inferences about the point in a surveyed series of observations at which the underlying distribution changes has been extensively addressed in the economics, biostatistics and statistics literature. Cumulative sum‐type statistics have commonly been thought to play a central role in non‐sequential change point detections. Alternatively, we present and examine an approach based on the Shiryayev–Roberts scheme. We show that retrospective change point detection policies based on Shiryayev–Roberts statistics are non‐asymptotically optimal in the context of most powerful testing.

We consider a specific classification problem in the context of change-point detection. We present generalized classical maximum likelihood tests for homogeneity of the observed sample in a simple form which avoids the complex direct estimation of unknown parameters. This paper proposes a martingale approach to transformation of test statistics. For sequential and retrospective testing problems, we propose the adapted Shiryayev-Roberts statistics in order to obtain simple tests with asymptotic power one. An important application of the developed methods is in the analysis of exposure's measurements subject to limits of detection in occupational medicine. © 2009 Taylor & Francis.

This paper focuses on modeling the gait characteristics of a quadrupedal gallop. There have been a number of studies of the mechanics of the stance phase in which a foot is in contact with the ground. We seek to put these studies in the context of the stride, or overall motion cycle. The model used is theoretical, and is kept simple in the interest of transparency. It is compared to empirical data from observations of animals, and to data from experiments with robots such as our KOLT machine, and results from sophisticated simulation studies. Modeling of the energy loss inherent in the interaction between the system and the environment plays a key role in the study. Results include the discovery of a hidden symmetry in the gait pattern, usually regarded as being completely asymmetrical. Another result demonstrates that the velocities with which the two front feet impact and leave the ground are different, and similarly for the rear feet. The velocities of the foot pairs mirror each other. This is consistent with empirical observation, but is at variance with the assumption used almost universally when modeling stance. A further result elicits the importance of the pitch moment of inertia and other effects that make the mammalian architecture, in which the center of mass is closer to the shoulders than to the hips, beneficial..

A novel use of the spectral method to determine excess pore water pressure during vertical consolidation of multi-layered soil with time constant material properties is presented, considering a unit cell with combined vertical and radial drainage. Equal strain conditions are assumed in the analysis. The novel adoption of material properties that vary in a linear fashion with depth allows arbitrary distributions of properties to be modelled. By incorporating surcharge and vacuum loading that vary with both depth and time, a wide range of consolidation problems can be analysed. The spectral method is a meshless approach producing a series solution to the consolidation problem based on matrix operations. Accuracy can be improved by increasing the number of terms used in the series solution. The model is verified by the analysis of selected case studies characterised by: analytical free strain consolidation with thin sand layers (surcharge only); laboratory test and embankment trial with surcharge and vacuum loading; and ground subsidence caused by groundwater pumping.

Purpose - Matching relevant ontology data for integration is vitally important as the amount of ontology data increases along with the evolving Semantic web, in which data are published from different individuals or organizations in a decentralized environment. For any domain that has developed a suitable ontology, its ontology annotated data (or simply ontology data) from different sources often overlaps and needs to be integrated. The purpose of this paper is to develop intelligent web ontology data matching method and framework for data integration. Design/methodology/approach - This paper develops an intelligent matching method to solve the issue of ontology data matching. Based on the matching method, it also proposes a flexible peer-to-peer framework to address the issue of ontology data integration in a distributed Semantic web environment. Findings - The proposed matching method is different from existing data matching or merging methods applied to data warehouse in that it employs a machine learning approach and more similarity measurements by exploring ontology features. Research limitations/implications - The proposed method and framework will be further tested for some more complicated real cases in the future. Originality/value - The experiments show that this proposed intelligent matching method increases ontology data matching accuracy. © Emerald Group Publishing Limited.

Global Navigation Satellite System (GNSS) Receiver Autonomous Integrity Monitoring (RAIM) is essential for safety-of-life and liability critical applications. This paper discusses two fundamentally different ways to assess the integrity risk of an operation with RAIM, based on a different amount of information available: the expected (or average) performance that is computed using the GNSS models only and the real-time (or actual) performance, which also uses information on the internal status of a GNSS receiver. It is shown both theoretically and by simulation that the real-time integrity risk significantly exceeds the expected risk after the detection and exclusion of a failing satellite. Therefore, while most published RAIM algorithms base their performance assessment on the expected performance only, this is only correct when the requirements allow the risk evaluation to be averaged over multiple operations. However, when the GNSS integrity requirement is to be applied on a ‘per operation’ basis, real-time integrity measures are more appropriate.

Clients select contractors on the basis of the relative importance of tender evaluation criteria, such as, experience, expertise, past performance, and cost. This paper presents the results of a recent study that sought to identify a suite of representative (principal) tender evaluation and contractor selection criteria for use in future research. The study included an examination of management literature on contractor selection and tender evaluation, and an exploratory survey. For each we developed a separate master list and mapped all identified and reported criteria into one of 16 defined categories. Threshold tests were applied to identify common and unique categories and an absolute difference test to determine the principal categories of criteria used in the evaluation of tenders. The study, using a pragmatic and heuristic approach, resulted in the identification of eight principal categories suitable for our research program. The findings indicate that the preferred criteria for evaluating tenders are those which provide a measure of contractors' ability in terms of their management and technical capability, past experience and performance, reputation, and the proposed method of delivery or technical solution.

The oxidation characteristic of stainless steel 304L in humid air and the deformation behaviour of the oxide scale during hot rolling at 1050 degrees C were investigated. The surface roughness transfer during hot rolling was discussed. With ail increase of reduction, the oxide scale thickness decreases linearly, the Surface roughness also decreases obviously and the integrity of oxide scale increases. The thickness decrease of thick oxide scale is more rapid than a thin oxide scale. The surface roughness always decreases with an increase of reduction, and the oxide scale thickness affects the surface roughness transfer during hot rolling.

In rolling process, the contact friction is of crucial importance for accurate modeling, optimum design and control of industrial rolling processes. It is important to characterize the features of the oxide scale of stainless steel in hot strip rolling because the scale on the strip surface affects friction coefficient and thermal conductivity coefficient. To some extent, the rolling force and friction condition depend on the thickness and the microstructure of the oxide scale. Oxidation tests of stainless steels 304 and 304L were carried out in a high temperature electric resistance furnace. The humid air in which the water vapour content can be controlled was generated and remained to flow into the chamber of the furnace in 2.5 x 10(-4) m(3)/s to study the effect of humidity on the oxidation of stainless steels. The microstructure and thickness of oxide scale layer of stainless steels were obtained and two or three oxide layers can be found. The humid air has a significant effect on the growth of oxide scale. Hot rolling tests were carried out on Hille 100 rolling mill. The friction condition at the roll-strip interface during hot rolling of stainless steel was determined and the transfer of surface roughness was discussed.

Both longitudinal and transverse frictions arising from plane strain during cold metal forming are of crucial importance for the accurate modelling, optimum design, and control of industrial processes. However, the influence of the friction and roughness along the transverse direction has been neglected in much previous research. Oblique roughness textures are considered, and the scale of roughness asperities is enlarged in this study. Four types of prism patterns, in which the angles between the longitudinal direction and the top line of prism are 90 degrees, 60 degrees, 30 degrees, and 0 degrees, and three types of pyramid patterns, in which the top angles are 151.9 degrees, 161.1 degrees, and 168.6 degrees, were designed and manufactured using samples of annealed Al 6060T5. All compression tests were completed in 10 passes, and the total displacement of the pressure head was 5.4 mm. The first five passes were carried out on an Instron 8033 Materials Testing Machine, and the last five passes on a 500-ton compression-testing machine. The surface morphologies of the deformed peak were analysed, and the top areas of the deformed peak were measured. The effects of the angle between the longitudinal direction and the top line of the prism texture or the top angle of the pyramid texture on the surface morphology of the deformed peak are not obvious. The angles have a relatively significant effect on the deformation behaviour of the surface layer during cold metal forming when the deformation is small. The pattern with a top angle of 161.1 degrees, which is the closest to the real value, shows the highest deformation resistance when the displacement of the pressure head is less than 1.2 mm.

A circularly polarized slot array suitable for millimeter wave WPAN applications is presented. The array uses a new type of circularly polarized element, comprising a circular slot loaded with an elliptical patch, and is fed by a microstrip line. The array is implemented on liquid crystal polymer (LCP), which is both low-loss and low-cost. A total of 8 array elements are used in a 4 × 2 configuration to achieve a maximum gain target of greater than 14 dBic. Sequential rotation of the elements within each of the 2 × 2 sub-arrays is used to increase the axial ratio bandwidth. Other novel features of the array are the finite ground plane, and open cavity structure used to support the LCP substrate of the slot array above a reflector plate. Measured and computed results presented for the packaged array confirm its wide impedance, axial ratio, and gain bandwidths. The effect of the packaged array back-short on the measured axial ratio is also discussed. © 2009 IEEE.

IEEE 802.15.4 protocol is proposed to meet the low latency and energy consumption needs in low-rate wireless applications, however, few analytical models are tractable enough for comprehensive evaluation of the protocol. To evaluate the IEEE 802.15.4 slotted CSMA/CA channel access mechanism in this paper, we propose a practical and accurate discrete Markov chain model, which can dynamically represent different network loads. By computing the steady-state distribution probability of the Markov chain, we obtain an evaluation formula for throughput, energy consumption, and access latency. Then we further analyze the parameters that influence performance including packet arrival rate, initial backoff exponent and maximum backoff number. Finally, NS2 simulator has been used to evaluate the performance of the 802.15.4 CSMA/CA mechanism under different scenarios and to validate the accuracy of the proposed model. © 2009 Springer.

PurposeSelf‐ and peer assessment has proved effective in promoting the development of teamwork and other professional skills in undergraduate students. However, in previous research approximately 30 percent of students reported that its use produced no perceived improvement in their teamwork experience. It was hypothesised that a significant number of these students were probably members of a team that would have functioned well without self‐ and peer assessment and hence the process did not improve their teamwork experience. This paper aims to report the testing of this hypothesis.Design/methodology/approachThe paper reviews some of the literature on self‐ and peer assessment, outlines the online self‐ and peer assessment tool SPARKPLUS, and analyses the results of a post‐subject survey of students in a large multi‐disciplinary engineering design subject.FindingsIt was found that students who were neutral as to whether self‐ and peer assessment improved their teamwork experience cannot be assumed to be members of well‐functioning teams.Originality/valueTo increase the benefits for all students it is recommended that self‐ and peer assessment focuses on collaborative peer learning, not just assessment of team contributions. Furthermore, it is recommended that feedback sessions be focused on learning not just assessment outcomes and graduate attribute development should be recorded and tracked by linking development to categories required for professional accreditation.

PurposeAs a way of focusing curriculum development and learning outcomes universities have introduced graduate attributes, which their students should develop during their degree course. Some of these attributes are discipline‐specific, others are generic to all professions. The development of these attributes can be promoted by the careful use of self‐ and peer assessment. The authors have previously reported using the self‐ and peer assessment software tool SPARK in various contexts to facilitate opportunities to practise, develop, assess and provide feedback on these attributes. This research and that of the other developers identified the need to extend the features of SPARK, to increase its flexibility and capacity to provide feedback. This paper seeks to report the results of the initial trials to investigate the potential of these new features to improve learning outcomes.Design/methodology/approachThe paper reviews some of the key literature with regard to self‐ and peer assessment, discusses the main aspects of the original online self‐ and peer assessment tool SPARK and the new version SPARKPLUS, reports and analyses the results of a series of student surveys to investigate whether the new features and applications of the tool have improved the learning outcomes in a large multi‐disciplinary Engineering Design subject.FindingsIt was found that using self‐ and peer assessment in conjunction with collaborative peer learning activities increased the benefits to students and improved engagement. Furthermore it was found that the new features available in SPARKPLUS facilitated efficient implementation of additional self‐ and peer assessment processes (asses...

Purpose: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children. Current chemotherapy regimes include the topoisomerase II poison etoposide and the transcription inhibitor actinomycin D. Poor clinical response necessitate identification of new agents to improve patient outcomes. Methods: We assessed the in vitro cytotoxicity (MTT assay) of DNA intercalating agents in five established human RMS cell lines. These include novel classes of transcription inhibitors and topoisomerase poisons, previously shown to have potential as anti-cancer agents. Results: Amongst the former agents, bisintercalating bis(9-aminoacridine-4-carboxamides) linked through the 9-position, and bis(phenazine-1-carboxamides) linked via their side chains, are compared with established transcription inhibitors. Amongst the latter, monofunctional acridine-4-carboxamides related to N-[2-(dimethylamino)ethyl] acridine-4-carboxamide, DACA, are compared with established topoisomerase poisons. Conclusions: Our findings specifically highlight the topoisomerase poison 9-amino-DACA, its 5-methylsulphone derivative, AS-DACA, and the bis(phenazine-1-carboxamide) transcription inhibitor MLN944/XR5944, currently in phase I trial, as candidates for further research into new agents for the treatment of RMS. © 2009 Springer-Verlag.

This article presents an experimental and numerical investigation into the influence of transverse stitching on failure of composite L-joints under tensile loading. Six unstitched and six stitched L-joint specimens were manufactured and tested under quasi static tensile loading. It was observed that the average measured failure load and the associated crosshead displacement for the stitched L-joint specimens are increased significantly compared to those for the unstitched specimens. Full 3D and 2D plane strain finite element (FE) models were developed to simulate both stitched and unstitched L-joints with an implemented stitch element. The load—displacement curves and results predicted via FE models compare favorably with the experimental results. For the stitched L-joints, it is shown that the observed delamination in the elbow region of the flange can be modeled by using a softening model for epoxy layer.

Currently, there are adequate guidelines available for FRP retrofitting RC structures against static and seismic loads. However, there is still limited information on retrofitting RC structures against short-duration dynamic loading effects such as blast loading. Due to the increasing threat of terrorism in recent years, retrofitting of RC structures against blast loading is of paramount importance in structural engineering. In this paper, a dynamic model that is based on single-degree-of-freedom (SDOF) approach is developed for the analysis of the response of retrofitted fixed end supported RC slabs subjected to blast loads. A previously validated layered capacity analysis method is used to determine the yielded and ultimate blast resistant capacity of a cross-section of a RC slab which allows varying strain rates with time along the depth of the member. The corresponding deflections are determined by plastic hinge analysis. To simplify the calculation process, a tri-linear resistance-deflection function which consists of elastic, elasto-plastic and plastic region for fixed end supported RC slabs is converted to an equivalent bilinear function. This developed model can adequately predict the retrofitted members' response to blast loading. It is then is used to conduct a parametric study to optimise the retrofitting of RC slabs subjected to blast loading by varying the quantity, material type and technique of retrofitting.

Fibre reinforced polymer (FRP) retrofitting of RC structures against blast loading is an emerging research area of major significance. Currently, several guidelines are available for the FRP retrofitting of RC structures against monotonic and seismic loads. However, no advice is provided from these guidelines for the retrofit RC structures against blast loading. This paper formulates a layered model that allows for both FRP strengthening and the consideration of strain rate effects on the blast resistant capacity of flexural structural members. The layered model is incorporated into a single degree of freedom model for dynamic analyses and it is validated with blast tests. The validated model is then used in a parametric study which investigates the changes in strength, ductility and energy absorption capacities of flexural FRP strengthened members under blast loads. It is found that the capacity of a flexural member to resist a blast load can be increased greatly with the use of compressive face plating with the ductility of the flexural member being the key factor.

Displacement-controlled design method is now being used by current guidelines such as TM5 and ASCE to design RC members against airblast load. If the maximum deflection of the designed member under airblast loads is less than the allowable deflection, the designed member is considered to be safe. Although the displacement-controlled design method is easy to use, it may not result in a design having maximum energy-absorption capacity against airblast loads, especially for a design of a reinforced ultra-high performance fibre concrete (RUHPFC) member which is of both high strength and high ductility, that is, high energy-absorption capacity. In this paper, a layered analysis model allowing for varying strain rates with time as well as along the depth of the member was used to calculate energy-ab sorption of a simple supported RUHPFC slab under airblast loads. An optimal reinforcement ratio of the slab was achieved by maximizing the energy absorption of the slab under different reinforcement ratios. The energy-controlled design method was validated by field blast tests. Using the validated design method, a designed slab with the optimal reinforcement ratio was also tested and the effectiveness of the design was demonstrated.

AbstractUsing quantum chemical descriptors and partial least squares (PLS) regression, a quantitative structure–activity relationships (QSARs) model was developed to predict the depuration rate constants (kd) of polycyclic aromatic hydrocarbons (PAHs) for mussels, Elliptio complanata (log kd=−2.1406+0.6013DE−2.0767×10−3 Mw−0.201EHOMO). With a high cumulative cross‐validated regression coefficient value (Q$\rm{ {_{cum}^{2}}}$) of 0.927 and low standard deviation (SD) of 0.065, the model obtained by the training set shows a good predictive ability, and it is validated to be robust by predicting the test set. Among 20 quantum chemical descriptors, the dielectric energy (DE), the molecular weight (Mw), and the highest occupied molecular orbital energy (EHOMO) are the key descriptors governing the logkd values in the model. Increase in the DE or decrease in the Mw values leads to the increase in logkd, indicating the van der Waals interactions and steric hindrance effect on the depuration process. Decrease in the EHOMO values results in increasing the logkd values, implying important roles the molecular orbital energies may play in the biological depuration of PAHs in m...

Although vibration-based structural damage detection methods have demonstrated various degrees of success, the damage detection of civil structures still remains as a challenging task. The main obstacles include the insensitivity to local damage and the high sensitivity to measurement noise. A new structural damage detection method based on the statistical moments of dynamic responses of a structure has been recently proposed by the authors, and the numerical study manifested that the proposed method is sensitive to local structural damage but insensitive to measurement noise. The experimental investigation on this method is presented in this article. Three shear building models with and without damage were built and subjected to ground motions generated by a shaking table. The displacement and acceleration responses of each building model at each floor were recorded. The recorded ground motion and building responses as well as identified structural damping ratios were then used to identify damage locations and severities using the statistical moment-based damage detection method. The identified damage locations and severities were compared with the theoretical values. The comparison is found satisfactory, and the method proposed is effective and feasible.

Association rules are an important problem in data mining. Massively increasing volume of data in real life databases has motivated researchers to design novel and incremental algorithms for association rules mining. In this paper, we propose an incremental association rules mining algorithm that integrates shocking interestingness criterion during the process of building the model. A new interesting measure called shocking measure is introduced. One of the main features of the proposed approach is to capture the user background knowledge, which is monotonically augmented. The incremental model that reflects the changing data and the user beliefs is attractive in order to make the over all KDD process more effective and efficient. We implemented the proposed approach and experiment it with some public datasets and found the results quite promising.

In this article, a novel and normalized Z-transform finite-difference time-domain (ZTFDTD) method is presented. This method uses a more general form of Maxwell's equations using the E, H, D fields. The iterative model of D-E-H-D can be obtained by using the Z-transform resulted frequency-dependent formula between D and E. The advantages of the ZTFDTD consist in that the discrete equations are simple, the results are precise, easy to program and capable of dealing with the key technologies of finite-difference time-domain (FDTD), such as absorbing boundary conditions (uniaxial anisotropic perfectly matched layer, UPML) and near-to-far-field transformation. The ZTFDTD method is then used to simulate the interaction of electromagnetic wave with plasma. Using a simplified two-dimensional model, the stealth effect of inhomogeneous, unmagnetized plasma is studied both in different electron densities of plasma, different electromagnetic wave frequencies and different plasma collision frequencies. The numerical results indicate that plasma stealth is effective in theory and a reasonable selection with the plasma parameters that can greatly enhance the effectiveness of plasma stealth. © 2009 Higher Education Press and Springer-Verlag GmbH.

This paper presents a novel radial basis function (RBF) collocation method to solve the moving conductor eddy current problem. The magnetic field is considered an addition of two fields generated respectively by the excitation current and the eddy current according to the source superposition principle. The corresponding governing equations are decoupled and solved with the RBF. Moving coordinate systems in which the separate fields are computed are also constructed to avoid the model reconfiguration caused by the motion. Electromagnetic field equations are analyzed with kinetic equations and circuit equations together to simulate the motion process. A practical engineering problem is computed to verify the method.

In this paper a comprehensive nonlinear model of surface mounted permanent magnet synchronous machine (SPMSM) is proposed considering both the structural and the saturation saliencies to enable the numerical simulation of new rotor position detection algorithms. With an identifiable parameter matrix, a numerical nonlinear inductance model is developed, in which the rotor position and the stator current are taken as the variables. After experimentally identifying out all the parameters, a nonlinear mathematic model of SPMSM is built up. With all the machine dimensions and physical parameters, finite-element analysis (FEA) is applied to calculate the magnetic field of the machine. FEA and performance simulation results are used to verify the new nonlinear model, which can be further used as a virtual model to develop, simulate, and verify the saturation saliency detection strategies.

A classical circuit can be represented by a circuit graph or equivalently by a Boolean expression. The advantage of a circuit graph is that it can help us to obtain an intuitive understanding of the circuit under consideration, whereas the advantage of a Boolean expression is that it is suited to various algebraic manipulations. In the literature, however, quantum circuits are mainly drawn as circuit graphs, and a formal language for quantum circuits that has a function similar to that of Boolean expressions for classical circuits is still missing. Certainly, quantum circuit graphs will become unmanageable when complicated quantum computing problems are encountered, and in particular, when they have to be solved by employing the distributed paradigm where complex quantum communication networks are involved. In this paper, we design an algebraic language for formally specifying quantum circuits in distributed quantum computing. Using this language, quantum circuits can be represented in a convenient and compact way, similar to the way in which we use Boolean expressions in dealing with classical circuits. Moreover, some fundamental algebraic laws for quantum circuits expressed in this language are established. These laws form a basis of rigorously reasoning about distributed quantum computing and quantum communication protocols.

We introduce an algebra qCCS of pure quantum processes in which communications by moving quantum states physically are allowed and computations are modeled by super-operators, but no classical data is explicitly involved. An operational semantics of qCCS is presented in terms of (nonprobabilistic) labeled transition systems. Strong bisimulation between processes modeled in qCCS is defined, and its fundamental algebraic properties are established, including uniqueness of the solutions of recursive equations. To model sequential computation in qCCS, a reduction relation between processes is defined. By combining reduction relation and strong bisimulation we introduce the notion of strong reduction-bisimulation, which is a device for observing interaction of computation and communication in quantum systems. Finally, a notion of strong approximate bisimulation (equivalently, strong bisimulation distance) and its reduction counterpart are introduced. It is proved that both approximate bisimilarity and approximate reduction-bisimilarity are preserved by various constructors of quantum processes. This provides us with a formal tool for observing robustness of quantum processes against inaccuracy in the implementation of its elementary gates.

Abstract. Geomophological hazard assessment is an important component of natural hazard risk assessment. This paper presents GIS-based geomorphological hazard mapping in the Red Sea area between Safaga and Quseir, Egypt. This includes the integration of published geological, geomorphological, and other data into GIS, and generation of new map products, combining governmental concerns and legal restrictions. Detailed geomorphological hazard maps for flooding zones and earth movement potential, especially along the roads and railways, have been prepared. Further the paper illustrates the application of vulnerability maps dealing with the effect of hazard on urban areas, tourist villages, industrial facilities, quarries, and road networks. These maps can help to initiate appropriate measures to mitigate the probable hazards in the area.

The location information of sensor nodes in wireless sensor networks is crucial for various applications such as emergency rescue operations, environmental monitoring, home automation, and traffic control. In this paper, a new method to improve the anchor location accuracy in wireless sensor networks is proposed based on fusion of Global Positioning System (GPS) measurements and anchor-to-anchor parameter estimates. Novel algorithms are derived to increase the accuracy of anchor locations using both anchor-to-anchor distance and angle-of-arrival (AOA) estimates for both line-of-sight (LOS) and non-LOS (NLOS) scenarios. When using anchor-to-anchor distance estimates in LOS conditions, an optimization-based algorithm is developed. The Cramer-Rao lower bound (CRLB) is derived to benchmark positioning accuracy in 3-D environments with both GPS measurements and anchor-to-anchor parameter estimates, which has not been studied in the literature. Simulation results demonstrate that the proposed algorithms can substantially improve anchor position accuracy, and the performance of the proposed algorithms approaches the CRLB. © 2008 IEEE.

A hybrid anchor-free localisation scheme for multihop wireless sensor networks is presented. First, a relatively dense group of nodes is selected as a base, which are localised by using the multidimensional scaling method. Secondly, the robust quads (RQ) method is employed to localise other nodes, following which the robust triangle and radio range (RTRR) approach is used to perform the localisation task. The RQ and the RTRR methods are used alternately until no more nodes can be localised by the two approaches. Simulation results demonstrate that the proposed hybrid localisation algorithm performs well in terms of both accuracy and the success rate of localisation. To evaluate the accuracy of anchor-free localisation algorithms, the authors derive two different accuracy measures: the Cramer-Rao lower bound (CRLB) to benchmark the coordinate estimation errors and the approximate lower bound to benchmark the distance errors. Simulation results demonstrate that both the CRLB and the distance error lower bound provide references for the accuracy of the location algorithms. © 2009 The Institution of Engineering and Technology.

Nonline-of-sight (NLOS) propagation is one of the challenges in radio positioning. Significant attention has been drawn to the mitigation of the NLOS effect in recent years. This paper focuses on the identification of NLOS conditions by employing the statistical decision theory. A Neyman-Pearson (NP) test method is first derived for scenarios where either 1-D or 2-D angular measurements are provided. A time-of-arrival (TOA) based method is then developed under idealized conditions to provide a performance reference. In the presence of both TOA and received signal strength (RSS) measurements, a joint identification method is derived to efficiently exploit the TOA and RSS measurements. Analytical expressions of the probability of detection (POD) and the probability of false alarm (PFA) are derived for all the scenarios considered. Two theorems and one corollary regarding the line-of-sight (LOS) conditions based on the angle of arrival (AOA) are also presented, and the proofs are provided. Simulation results demonstrate that the proposed methods perform well, and the joint TOA- and RSS-based method considerably outperforms the TOA-based methods. The proposed methods are robust to the model errors, as demonstrated through simulations. It is also shown that the analytical results agree well with the simulated ones. © 2009 IEEE.

Locating sensor nodes in an ad hoc wireless sensor network (WSN) is a challenging task. In general, the network nodes are not synchronised and the internal delays within the nodes are unknown. Here, time-of-arrival (TOA)-based localisation is investigated when practical parameters such as clock time offset, clock frequency offset and system internal delay are all involved. The TOA measurements are made between each pair of nodes that are within radio range. First, an efficient frequency offset (FO) estimation algorithm is derived. Then, a two-stage localisation scheme is proposed. In the first stage, localisation starts from the nodes with the largest numbers of neighbouring anchors and priority is always given to nodes with more neighbouring anchors and/or localised nodes. In the second stage, the locations of all neighbouring nodes are exploited to improve location accuracy. Two iterative algorithms are developed: the Taylor series-based least squares (TS-LS) method and the sequential quadratic programming (SQP) optimisation method. During the localisation process, a number of measures are taken to ensure the reliability of each location estimate to avoid abnormal errors and reduce error propagation. The Cramer-Rao lower bound is also derived to benchmark the location accuracy. © The Institution of Engineering and Technology 2009.

Tensor rank refers to the number of product states needed to express a given multipartite quantum state. Its non-additivity as an entanglement measure has recently been observed. In this note, we estimate the tensor rank of multiple copies of the tripartite state $\ket{W}=\tfrac{1}{\sqrt{3}}(\ket{100}+\ket{010}+\ket{001})$. Both an upper bound and a lower bound of this rank are derived. In particular, it is proven that the tensor rank of $\ket{W}^{\otimes 2}$ is seven, thus resolving a previously open problem. Some implications of this result are discussed in terms of transformation rates between $\ket{W}^{\otimes n}$ and multiple copies of the state $\ket{GHZ}=\tfrac{1}{\sqrt{2}}(\ket{000}+\ket{111})$.

A cross-correlating 186-GHz passive millimeter-wave imager has been built. The key components in the signal processing hardware are two 186-GHz receivers and a broadband complex correlator. To evaluate the performance of this imager, its point-spread function, beam pattern, baseline vector, and their variations with the scanning direction have been experimentally measured and derived. Some of these results are needed for optimizing the imager’s parameter settings. Others are required for implementing the modulated-beam and modulated-scene algorithms proposed in a previous paper dealing with the imager’s fringe in its point-spread function. These results will also reveal any problems in the construction process of the imager. The theoretical bases for these measurements are analyzed. Novel algorithms for deriving each antenna’s point-spread function and beam pattern, as well as the imager’s baseline vector from the measurement results of the imager’s point-spread function and beam pattern are proposed and successfully applied in the measurements. Experimental results are presented and discussed. © 2009 IEEE.

As a method of preparing ligand-selective cavities in a synthetic polymer matrix, molecular imprinting technique has been attracting significant interest from a large number of areas in chemistry and analytical sciences. In this study, molecularly imprinted polymers (MIPs) were prepared with styrene, 4-vinylpyridine (4-VPy), and divinylbenzene (DVB) for the separation of hazardous 2,4-dichlorophenoxyacetic acid (2,4-D), and the selectivity of MIPs as adsorbed 2,4-D and structurally similar materials was evaluated. The template was removed through the swelling process of toluene/ethanol, and the removal ratio was about 95-99%, respectively. MIPs synthesized in this study had good adsorption selectivity in the presence of other materials, although there was a difference of adsorption quantities (uptake) in the functional monomer (4-VPy contents) and the cross-linker (DVB contents). The results exhibit that the selectivity of MIPs was improved significantly by controlling the cross-linker. We expect that molecular imprinting technique will serve as a novel method for selective separation of specific materials in various fields, especially in the fields of environment and pharmaceutics.

This paper presents the thermal analysis of a high-speed motor with soft magnetic composite (SMC). Due to the high operation frequency, the core loss is much greater than the other losses and, hence, is the major heat source in the high-speed motor. Therefore, it is of crucial importance to be able to calculate the core loss accurately. In this paper, the rotational core-loss model is employed and implemented by using 3-D magnetic-field analysis (FEA). Two methods to model the thermal behavior are presented. The first method uses a combination of lumped and distributed thermal parameters, which are obtained from motor dimensions and thermal constants. The second method employs 3-D FEA to accurately calculate the temperature distribution. Core losses are directly coupled into the thermal calculation by keeping the same hexahedral meshing for magnetic-field analysis and thermal analysis. A testing bench for the high-speed SMC motor prototype has been set up to measure the core loss. The temperature rises were measured by thermal probes. The calculation and measurement results are compared and discussed.

Some multi-objective decision-making (MODM) methods are more effective than others for particular decision problems and/or particular decision makers. It is therefore necessary to provide a set of MODM methods in a multi-objective decision support system (MODSS) to support a wide range of problem solving. However, it is always difficult for decision makers to select the most suitable method for individual cases because MODM methods involve a deep knowledge of mathematics. To handle this difficulty, this study develops a MODM method selection guide supported by a fuzzy matching optimization method. In this paper, we first present the modelling process for the knowledge of characteristics of the main MODM methods. We then present related matching techniques between the characteristics of a real-world decision-making situation and a set of predefined situation descriptions (characteristics of a MODM method) where the elements of the two sets may be expressed by linguistic terms. Based on this process, a fuzzy matching optimization-based MODM method selection approach is proposed. The approach applies general fuzzy numbers, fuzzy distance, fuzzy multi-criteria decision-making concepts, and rule-based inference techniques to recommend the most suitable method from a MODM method-base. The approach is adopted in a linguistic intelligent user guide within a MODSS. Experiments have shown that the development of the linguistic intelligent user guide can increase the ability of the MODSS to support decision makers in arriving at a satisfactory solution in a most effective way. © 2009 Elsevier Inc.

A complex fuzzy set is a fuzzy set whose membership function takes values in the unit circle in the complex plane. This paper investigates various operation properties and proposes a distance measure for complex fuzzy sets. The distance of two complex fuzzy sets measures the difference between the grades of two complex fuzzy sets as well as that between the phases of the two complex fuzzy sets. This distance measure is then used to define δ-equalities of complex fuzzy sets which coincide with those of fuzzy sets already defined in the literature if complex fuzzy sets reduce to real-valued fuzzy sets. Two complex fuzzy sets are said to be δ-equal if the distance between them is less than 1 - δ. This paper shows how various operations between complex fuzzy sets affect given δ-equalities of complex fuzzy sets. An example application of signal detection demonstrates the utility of the concept of δ-equalities of complex fuzzy sets in practice. © 2009 Elsevier Inc. All rights reserved.

Emergency risk management (ERM) is a process which involves dealing with risks to the community arising from emergency events. Emergency management evaluation as one of the important parts of ERM aims assessing and improving social preparedness and organizational ability in identifying, analyzing, and treating emergency risks. This study first develops an emergency management evaluation model. It then proposes an extended fuzzy multi-criteria group evaluation method, which can deal with both subjective and objective criteria under multi-levels by a group of evaluators, for emergency management evaluation. A fuzzy multi-criteria group decision support system (FMCGDSS) is then developed to implement the proposed method for the case of emergency operating center/system evaluation. © Springer-Verlag 2008.

In this study, the critical fl ux of the submerged membrane system was experimentally evaluated when it was used for seawater with and without pre-treatment. In this study, different processes such as fl occulation with ferric chloride (FeCl3) and different doses of PAC adsorption were used as a pre-treatment. The pretreatment of fl occulant of 2 mg/L of FeCl3 and adsorption with the dose of 1 g/L PAC showed an improvement in the critical fl ux from 5 L/m2.h to 6.7 L/m2.h and 13.3 L/m2.h respectively. The performance of these pretreatments was also determined in terms of modifi ed fouling index using ultrafi lter membrane (UF-MFI). UF-MFI and SDI indicated that PAC adsorption was a better pretreatment than fl occulation for the seawater used in this study. Molecular weight distribution (MWD) of seawater organic matter was also examined after different pretreatments. MWD of the raw seawater was mainly in the range from 1510 to 130 Da. It is observed that FeCl3 fl occulation and PAC adsorption as pretreatments partially removed the organic matter of 1510 Da and 130Da respectively

AbstractGenome‐wide microRNA (miRNA) expression profiling of salivary gland pleomorphic adenomas revealed a distinct expression signature consisting largely of upregulated miRNAs compared with matched normal tissue. Microarray data were confirmed by quantitative real time RT‐PCR (q‐RTPCR). Five miRNA genes upregulated in the tumours were found in close proximity to fragile sites and/or cancer associated genomic regions. Interestingly, q‐RTPCR revealed an increase in the expression of components of the miRNA processing machinery (Dicer, Drosha, DGCR8 and p68) in tumours suggesting that the deregulation of miRNA expression may result from increased miRNA biogenesis. Target gene prediction analysis of the altered miRNAs indicated that genes in a number of signalling pathways important in tumourigenesis including WNT, MAPK and JAK‐STAT were overrepresented. Significantly, the oncogene PLAG1 was overexpressed in our cohort and may be potentially regulated by these miRNAs. This is the first study to examine changes in the miRNA milieu in pleomorphic adenoma, the most common salivary gland tumour. This study has demonstrated an upregulation of both miRNAs genes and an upregulation of the miRNA processing machinery. These changes may be potential underlying mechanisms for the development of these benign tumours. © 2009 UICC

AbstractBecause of the lack of a uniform schema for web documents and the sheer amount and dynamics of web data, both the effectiveness and the efficiency of information management and retrieval of web data are often unsatisfactory when using conventional data management and searching techniques. To address this issue, we have adopted web mining and web community analysis approaches. On the basis of the analysis of web document contents, hyperlinks analysis, user access logs and semantic analysis, we have developed various approaches or algorithms to construct and analyze web communities, and to make recommendations. This paper will introduce and discuss several approaches on web community mining and recommendation. Copyright © 2009 John Wiley & Sons, Ltd.

Bilevel decision addresses the problem in which two levels of decision makers, each tries to optimize their individual objectives under certain constraints, act and react in an uncooperative, sequential manner. As bilevel decision making often involves many uncertain factors in real world problems, it is hard to formulate the objective functions and constraints of the leader and the follower in modelling a real bilevel decision problem. This study explores a new approach that uses rule sets to formulate a bilevel decision problem. It first develops related theories to prove the feasibility to model a bilevel decision problem by rule sets. It then proposes an algorithm to describe the modelling process. A case study is discussed to illustrate the functions and effectiveness of the proposed rule sets based bilevel decision modelling algorithm. © 2007 Elsevier Ltd. All rights reserved.

Conventional magnetization methods only measure the average magnetic properties over the whole sample. The information is insufficient to understand the local character. This paper presents the visualized magnetization process and its profiles in detail at the cross section of the FINEMET ribbon using advanced magnetooptical imaging technique. External magnetic fields were applied parallel to the surface of the ribbon. A magnetization curve was plotted by interpreting the profile of intensity of magnetooptical images. The profile indicates that the flux densities are higher at the cross section of the ribbons compared with those at the gaps between the ribbons. The flux lines mainly transmit inside the FINEMET ribbons though there are some stray fields between the ribbons.

The model recently presented by Sheng, Fredlund, and Gens, known as the SFG model, provides a consistent explanation of yield stress, shear strength, and volume change behaviour of unsaturated soils as functions of suction. All these functions are based on one single equation that defines the volume change with suction and stress changes. This paper provides a systematic validation of the equation and the derived shear strength criterion against experimental data. The experimental data used include those for samples prepared from slurry soils and compacted soils. It is shown that (i) the method currently used to determine yield stresses of unsaturated soils is incorrect, (ii) volume change behaviour of unsaturated soils can be well predicted by the SFG model, and (iii) shear strength behaviour of unsaturated soils can be represented very well by the criterion in the SFG model.

Various pharmaceutical residues are being discharged from wastewater treatment works (WTW) effluents, the impact of which on river water quality is of high relevance to environmental risk assessment. The concentrations of eleven pharmaceutical compounds were determined in three WTWs in England, and the river Ouse receiving effluents from Scaynes Hill WTW. Results show that five compounds propranolol, sulfamethoxazole, carbamazepine, indomethacine and diclofenac were detected in all wastewater and river water samples, with carbamazepine showing the highest concentrations (up to 2336 ng L-1) in WTW influent. Different compounds were removed to different extent in the WTWs, varying from 43 to 92%, with the highest performance obtained by the WTW with tertiary treatment (sand filtration). The pharmaceutical residues from Scaynes Hill WTW were eventually discharged into the river Ouse, causing an elevation in their concentrations downstream of the outfall. This was confirmed by the good agreement between measured concentrations and those predicted by a simple dilution model.

Studied herein are the signatures of nonlinear vibration characteristics of damaged reinforced concrete structures using the wavelet transform (WT). A two-span RC slab built in 2003 was tested to failure in the laboratory. Vibration measurements were carried out at various stages of structural damage. The vibration frequencies, mode shapes, and damping ratios at each loading stage were extracted and analyzed. It is found that the vibration frequencies are not sensitive to small damages, but are good indicators when damage is severe. The dynamic responses are also analyzed in the time–frequency domain by WT and the skeleton curve is constructed to describe the nonlinear characteristics in the reinforced concrete structures. The results show that the skeleton curves are good indicators of damage in the reinforced concrete structures because they are more sensitive to small damages than vibration frequencies.

The capacity of series of DNA-threading bis(9-aminoacridine-4-carboxamides) comprising ethylmorpholino, ethylpiperidine and N-methylpiperidin-4-yl sidechains joined by different linkers, to modulate gene expression in human leukaemia cells was investigated. The chosen compounds provided the opportunity for probing the relationships between the structure ligand structure and the drug effects on transcription, information that might lead to a greater understanding of their potential as antitumour agents. As revealed by DNA microarray analysis of 6000 genes, at equitoxic doses, 5xIC(50) values for growth inhibition, all of the drugs perturb transcription, resulting in both up- and down-regulation of many hundreds of genes, 24 h after drug exposure. Under these conditions, the capacity to inhibit transcription decreases in the order C3NC3 morpholino > C2pipC2 morpholino > C8 piperidine > C8NMP > C2pipC2 piperidine. Cluster analysis segregated the examined agents into two groups: the first included C2pipC2 morpholino and C3NC3 morpholino and the second C2pipC2 piperidine, C8 piperidine and C8NMP. This classification agreed with the ontological analysis for the markedly up-regulated genes that showed a relatively specific profile for each group. Interestingly, the general up-regulation responses for the first group (C3NC3 morpholino and C2pipC2 morpholino) indicated marked up-regulation amongst the transcription gene set, which suggests that the transcription machinery is the main target for the members of this group. While in the second group (C2pipC2 piperidine, C8 piperidine, C8NMP), the general up-regulation responses for the three agents are dominated by the protein modification process ontological class, implying at least involvement of topoisomerase poisoning in their mode of action.

A hybrid system for detecting driver drowsiness was examined by using piezofilm movement sensors integrated into the car seat, seat belt and steering wheel. Statistical associations between increase in the driver drowsiness and the non-invasive and conventional physiological indicators were investigated. Statistically significant associations were established for the analysed physiological indicators – car seat movement magnitude and (electroencephalogram) EEG alpha band power percentage. All of the associastions were physiologically plausible with increase in probability of drowsiness associated with increases in the EEG alpha band power percentage and reduction in the seat movement magnitude. Adding a non-invasive measure such as seat movement magnitude to any combination of the EEG derived physiological predictors always resulted in improvement of associations. These findings can serve as a foundation for designing the vehicle-based fatigue countermeasure device as well as highlight potential difficulties and limitations of detection algorithm for such devices.

This paper covers modeling, energy management strategy development, genetic algorithm (GA) optimization and simulation results based on the model of the UTS plug-in hybrid electric vehicle (PHEV). The UTS PHEV configuration consists of energy storage system, electric machine (EM), power control unit and internal combustion engine. The difference between the UTS PHEV and the conventional powertrain configurations is that the existing configurations need two EMs to function as the electric generator and motor, respectively, while the UTS PHEV needs only one EM to function as either a generator or electric motor in different time intervals specified by the energy management strategy and therefore, can save space, weight and cost. Extensive research has been conducted on the modeling and comparison of the new and existing powertrain configurations. The objective of this paper is to minimize the fuel consumption and greenhouse gas emissions by optimizing the powertrain parameters. The powertrain was simulated for a standard U.S environmental protection agency drive cycle, the highway drive cycle, and the optimization was performed by using the GA.

The proliferation of mesh or ad hoc network protocols has lead to a push for protocol standardisation. While there are a number of both open-source and proprietary mesh routing protocols being developed, there is only a small amount of literature available that shows relative strengths and weaknesses of different protocols. This paper investigates the performance of a number of available routing protocols using a real-world testbed. Three routing protocols - optimised link state routing (OLSR), better approach to mobile ad hoc network (B.A.T.M.A.N.) and BABEL - were chosen for this study. Our investigations focus on the multi-hopping performance and the ability of each routing protocol to recover from link failures. Our results show that B.A.T.M.A.N. and BABEL outperform OLSR both in terms of multi-hopping performance and in route re-discovery latency.

The consumption of fossil fuels spawns environmental considerations in addition to issues of energy demand, national security and resource availability. At global level, scientists warn that the combustion of fossil fuels is significantly changing the world's climate system. Local or regional concerns include smog, acid rain, and health implications of urban air pollution. Due to stringent emission norms and depletion of petroleum resources there has been a continuous effort to use alternative fuels such as hydrogen. It has its own benefits and limitations if it is used in conjunction with conventional fuel in diesel engine. The purpose of this article was to investigate the effect of hydrogen addition on performance and exhaust gas emission of stationary diesel engine. In this study, hydrogen was used as secondary fuel in a single cylinder 406 c.c. diesel engine. The hydrogen was injected through intake manifold and diesel was injected directly inside the combustion chamber. Series of experiments were conducted and it can be seen the effect of hydrogen addition in the increase of peak pressure from 5 bar to a maximum 21 bar, IMEP from 1.0 to 1.7 bar , indicated power from 4%-16%. There were also increases in NOx and CO emissions from 48-197 ppm and 423-758 ppm, respectively. Hydrogen addition causes increase in exhaust gas temperature from 3.1% to 10.2% particularly at 2500 rpm and reduction in O 2 emissions from 3.9% to 7.6% (by volume) throughout all engine speeds. ©2009 IEEE.

© 2009 EUCA. Multilevel Converters (MCs) have emerged as a promising alternative to traditional two level converters. These topologies present a better output voltage quality due to the reduction of the voltage steps by increasing the voltage number levels. Within the MC family, flying capacitor converters present a special attraction due to the easy way to increase output voltage levels by adding cells. Recently model predictive control algorithms have reached a special interest in MCs applications. In particular, finite control set predictive control algorithms applied to flying capacitor converters have shown that it is possible to achieve a good performance in the control of capacitor voltages and output current. For that purpose, at each sample time the controller explores all the switching states and determines the optimal one to be applied. However, the number of switching states grow exponentially in relation to the number of cells. This increases the time that the algorithm takes to find the optimal switching state. In this paper we present an off- line strategy to reduce the number of switching states to be explored in a finite control set predictive algorithm by using only those which produce that the system state point towards to the reference. Moreover, a sampling period design is presented to guarantee that the system state remains inside of a positive invariant set.

Remote health care monitoring is an emerging application that helps to reduce the cost of health care and at the same time improve its quality. However, by its nature, medical sensor data is often unreliable and massive as the data is collected from numerous sensors operating in noisy environments. Therefore, ensuring the reliability of the sensor data and the scalability of the health care monitoring services are among major challenge and is a determining factor in success of the system. In this paper, we propose a robust and flexible processing module as part of an active health care monitoring framework. It is responsible for preparing the sensor data and performing some initial assessment of the data for input to later modules. The proposed preprocessing architecture contains five stages ; validation, transformation, cleaning, reduction and cross-verification. The module is evaluated using synthetic blood pressure data.

This paper present a new routing protocol for Ad hoc networks, called On-demand Tree-based Routing Protocol (OTRP). This protocol combines the idea of hop-by-hop routing such as AODV with an efficient route discovery algorithm called Tree-based Optimized Flooding (TOF) to improve scalability of Ad hoc networks when there is no previous knowledge about the destination. To achieve this in OTRP, route discovery overheads are minimized by selectively flooding the network through a limited set of nodes, referred to as branching-nodes. The theoretical analysis and simulation results showed that OTRP outperforms AODV, DYMO, and OLSR and it reduces overheads as number of nodes and traffic increase.

This paper presents heterogeneity ratio (HR) as a new routing metric for heterogeneous MANETs. This metric is the ratio of number of powerful nodes to hop count that is used to select the best path to destination. Node heterogeneity is modeled in terms of: types and number of different interfaces, power, and transmission ranges. Our proposed routing metric is based on developing route discovery algorithm that is implemented on the top of on-demand tree-based routing protocol (OTRP)[2] to accommodate nodes heterogeneity. Simulation results show that using HR with OTRP heterogeneity aware outperforms other metrics like minimal hop count and maximal number of powerful nodes.

Accurate morphological characterization of the multiple neuronal classes of the brain would facilitate the elucidation of brain function and the functional changes that underlie neurological disorders such as Parkinson's diseases or Schizophrenia. Manual morphological analysis is very timeconsuming and suffers from a lack of accuracy because some cell characteristics are not readily quantified. This paper presents an investigation in automating the classification of dopaminergic neurons located in the brainstem of the rodent, a region critical to the regulation of motor behaviour and is implicated in multiple neurological disorders including Parkinson's disease. Using a Carl Zeiss Axioimager Z1 microscope with Apotome, salient information was obtained from images of dopaminergic neurons using a structural feature extraction technique. A data set of 100 images of neurons was generated and a set of 17 features was used to describe their morphology. In order to identify differences between neurons, 2-dimensional and 3-dimensional image representations were analyzed. This paper compares the performance of three popular classification methods in bioimage classification (Support Vector Machines (SVMs), Back Propagation Neural Networks (BPNNs) and Multinomial Logistic Regression (MLR)), and the results show a significant difference between machine classification (with 97% accuracy) and human expert based classification (72% accuracy). © 2009 IEEE.

Relating information originating from disparate sensors observing a given scene is a challenging task, particularly when an appropriate model of the environment or the behaviour of any particular object within it is not available. One possible strategy to address this task is to examine whether the sensor outputs contain information which can be attributed to a common cause. In this paper, we present an approach to localise this embedded common information through an indirect method of estimating mutual information between all signal sources. Ability of L1 regularization to enforce sparseness of the solution is exploited to identify a subset of signals that are related to each other, from among a large number of sensor outputs. As opposed to the conventional L2 regularization, the proposed method leads to faster convergence with much reduced spurious associations. Simulation and experimental results are presented to validate the findings.

Relating information originating from disparate sensors without any attempt to model the environment or the behaviour of any particular object within it is a challenging task. Inspired by human perception, the focus of this paper will be on observing objects moving in space using sensors that operate based on different physical principles and the fact that motion has in principle, greater power to specify properties of an object than purely spatial information captured as a single observation in time. The contribution of this paper include the development of a novel strategy for detecting a set of signals that are statistically dependent and correspond to each other related by a common cause. Mutual Information is proposed as a measure of statistical dependence. The algorithm is evaluated through simulations and three application domains, which includes, (1.) Grouping problem in images, (2.) Data association problem in moving observers with dynamic targets, and (3.) Multi-modal sensor fusion.

E-government is becoming more attentive towards providing intelligent personalized online services to citizens so that citizens can receive better services with less time and effort. This paper proposes a new conceptual framework for delivering personalized e-government services to citizens from a citizen-centric approach, called Pe-Gov service framework. This framework outlines the main components and their interconnections. Detailed explanations about these components are given and the special features of this framework are highlighted. This framework has the potential to outperform the existing e-Gov service systems as illustrated by two real life examples.

Wikispaces was piloted as an educational tool for improving teaching and learning at the School of Civil and Environmental Engineering, University of New South Wales with class of 54 enrolled students. An active and self-directed learning approach was used in this subject based on interactive/ discussion-based lectures and tutorials, debates and presentations as well as private study. Students experiences and readings were to be reflected through contributions to class and wiki discussions to facilitate brain-storming, inquisitions and facilitate students' learning from each other. This paper reflects on the use of Wikispaces as a teaching strategy and presents results of students' responses to a questionnaire about the use of the wiki tool, and general teaching and learning of the subject. Analyses of responses suggested that students expressed positive experiences using wikispaces and that wikispaces correlated positively with students' performance.

ABSTRACT. Experiments have been performed to investigate the heat loss and evaporation rate from an open-top tank of heated water that is also agitated vigorously by air bubbling through it. High consumption of electrical energy in heating the solutions for an electroplating process prompted this study; and the experimental set-up thus serves as a model for an electroplating tank in this process. Air is injected from the tanks floor, and an electrical heater is used to maintain water at a constant, elevated temperature, compensating the heat being lost to the surroundings. A heat transfer model is developed for the process and is seen to agree well with measurements. Waters evaporation rate is found to be proportional to the injected air flow rate, and that most of the supplied energy goes into evaporating the water.

Supporting users' reasoned imagination in sense making during interaction with tangible and embedded computation involves supporting the application of their existing mental schemata in understanding new forms of interaction. Recent studies that include an embodied metaphor in the interaction model, which relates action-based inputs to digital outputs, have provided evidence that this approach is beneficial. Yet the design of such systems has been difficult and full of setbacks. Wide spread adoption of this approach requires a better understanding of how to design such embodied metaphor-based interactional models. We analyze three recent design-based research studies in which we have been involved in order to derive design knowledge that may inform others. Following a case study methodology we identify kernels or points in the design process where discontinuities between predicted and actual interaction highlight important design knowledge.

Production of good quality pervious concrete is necessary to meet specification requirements for the construction of durable concrete pervious pavements. This paper reports and discusses the results of an experimental investigation into the physical and engineering properties ofpervious concrete having varying amounts of fly ash as the cement replacement material. The following properties were studied: porosity density, compressive strength weight loss on drying, free drying shrinkage and water permeability. The results thowed that porosity has significant effect on compressive strength and permeability of pervioos concrete. Replacement of cement with fly ash up to 50%, by mass ofbinder, had no significant effect on the water permeability and shrinkage ofshe pervious concrete, although marginal effect on strength was noticed.

There is more chance of a completed sale if the end customers and relationship managers are suitably matched. This in turn can reduce the number of calls made by a call centre reducing operational costs such as working time and phone bills. This chapter is part of ongoing research aimed at helping a CMC to make better use of its personnel and equipment while maximizing the value of the service it offers to its client companies and end customers. This is accomplished by ensuring the optimal use of resources with appropriate real-time scheduling and load balancing and matching the end customers to appropriate relationship managers. In a globalized market, this may mean taking into account the cultural environment of the customer, as well as the appropriate profile and/or skill of the relationship manager to communicate effectively with the end customer. The chapter evaluates the suitability of a MAS to a call management system and illustrates the requirement analysis phase using i∗ models.

This paper presents a novel input current shaper based on a quasi-active power factor correction (PFC) scheme. The power factor is improved by adding two auxiliary windings coupled to the transformer of a cascade dc/dc flyback converter. The auxiliary windings are placed between the input rectifier and the low-frequency filter capacitor to serve as a magnetic switch to drive an input inductor. Since the dc/dc converter is operated at high switching frequency, the auxiliary windings produce a high frequency pulsating source such that the input current conduction angle is significantly lengthened and the input current harmonics is reduced. It eliminates the use of active switch and control circuit for PFC. The input inductor can be designed to operate in discontinuous current mode (DCM) with lower harmonic content or continuous conduction mode (CCM) with higher efficiency. However, a trade-off between efficiency and harmonic content must be made. Operating principles, analysis, simulation and practical results of the proposed method are presented. © 2009 IEEE.

To optimise the performance of the wind generation, wind turbines employ variable speed (VS) variable pitch (VP) control system. Wind turbine is a complex nonlinear mechanical system exposed to uncontrolled wind profiles. Due to this, dynamic and parametric uncertainties arise in the mathematical model of the wind turbines over different operating conditions. This makes the turbine controller design a challenging task. This paper addresses the problem of designing robust control system for wind turbines in the presence of uncertainties using Minimax LQG (linear quadratic gaussian) design methodology. Using this approach the parameter variations and the model uncertainties are represented using Integral Quadratic Constraints (IQCs). Controllers are synthesised using LMI approach. The designed controllers provide robust performance in the presence of the specified uncertainties. Controllers are designed for a test case system and simulation results are presented. © 2009 IEEE.

A number of areas associated with current practices for floodplain modelling have been highlighted during the revision of ARR as requiring further investigation. One of these areas and hence the reason for one of the revision projects is the need for guidance on 2D modelling in urban areas. This need for guidance has increased as 2D models have become the tool of choice for prediction of flood behaviour within urban floodplains throughout Australia. These 2D models also are being used to simulate rainfall-runoff processes that traditionally have been modelled using conceptual lumped storage rainfall-runoff routing models. The revision project implemented to satisfy this need adopted a non-traditional approach. Instead of inviting a small group of authors to write the project report, a team of authors that represented model suppliers, experienced users, academics and clients from across Australia was assembled. The team used an online wiki tool to develop content collaboratively. Outlined in this paper are the process, experiences learned and details of the final report arising from this project.

Physical activity and manipulating physical objects can be beneficial for learning. Earlier studies [2] have shown that interaction models that rely on unconscious and embodied knowledge (based on embodied metaphors) can benefit the learning process. However, more than one embodied metaphor might be applicable. In this paper, we present the results of a user study (n=65) designed to identify embodied metaphors seven to nine year old children use when enacting abstract concepts related to musical sound. The results provide evidence that multiple different embodied metaphors can unconsciously be used to structure the understanding of these concepts. In addition, we have identified and categorized commonly used metaphors based on the children's enactments of changing sound concepts.

Since 1958, when it was first released, Australian Rainfall and Runoff has remained one of the most influential and widely used guidelines for estimation of flood flows in Australia. Since publication of the current edition, initially published in 1987, there have been advances in the theory of flood flows and changes in the application of engineering hydrology to the estimation of flood flows which warrant updating of the current document. One area where these advances have been significant has been in the understanding of the potential for climate change and the influence on current estimates of flood flows. As a result of these advances, the Federal Department of Climate Change in conjunction with EngineersAustralia has developed a funding package for the Australian Rainfall and Runoff Revision Projects. Presented herein are details of the projects undertaken as part of this funding package and how the information from these projects will be utilised in the revision of Australian Rainfall and Runoff.

This paper presents a genetic algorithm (GA) to assessment the decision making units (DMU). The Telecommunication sectors based on standards indicators identified by international telecommunication union (ITU) are considered for total assessment by the proposed approach. The indicators are categorized as telephone network size, other services, quality of service, traffic, tariffs, staff, demography, economy, information technology, broadcasting and mobile services. To present the applicability of the proposed approach, data for the year 2003 of 62 developed and developing countries are used. A total of 9 indicators are considered, out of which 4 are inputs and 5 are outputs respectively. The results of GA are verified by Principle Component Analysis (PCA) approach. The results show weak and strong points of each sector and identify the most efficient inputs or outputs, which can aid management in overall assessment. The proposed approach of this study may be easily used for assessment of other sectors. ©2009 IEEE.

This paper attempts to provide a definition of sustainable urban transport development. As will be shown, while the need to develop transport in a sustainable way has been widely accepted by many governments and transport practitioners, a consistent view on what is meant by sustainable transport is yet to develop. In an effort to address this, this paper begins by providing a systematic overview of the problems that the urban transport sector faces. It highlights shortcomings in the traditional ways that transport practitioners have approached the issue of sustainable transport development. In response, it proposes a different way of conceptualising the role of urban transport as a provider of access to services and facilitator of interaction and exchange in the urban system. In so doing it provides a new understanding and definition of what sustainable transport development could be in practice.

A combination of self and peer assessment is a powerful and rich teaching and learning management tool that can be used to monitor and evaluate group performance in project work. An on-line system (SPARKPLUS â Self and Peer Assessment Resource Kit) has been developed to simplify this process for the academic. This system generates factors for both the peer assessment weighting to be applied for individual contribution and the studentâs perception of their contribution compared to their peers by using key assessment criteria and a rigorous algorithm that is applied to the student evaluations of themselves and their peers. This paper describes and evaluates the introduction of SPARKPLUS to assess the performance of Mining Engineering Undergraduates in Year 3 at The University of Queensland in the first semester of 2008 in two of their core undergraduate courses that required group project work to be completed for assessment. The results obtained from this initial trial show the potential for improving student behaviour in group work through a structured approach to monitoring and feedback of their performance. It was found that male students with GPAs ⤠5 tend to overestimate their contribution to group work more frequently than their peers whereas the opposite applies for male students with GPAs > 5.

A mechanism capable of enhancing the safety of paths followed by mobile robots which significantly modify their mass distribution while operating in uneven terrains is presented. This is the case, for instance, of kinematically reconfigurable platforms or robots equipped with manipulator arms. For a given path, a trajectory optimiser that finds suitably safer paths in terms of tip-over prevention and equal force distribution over the supporting contact points is proposed. Other kinematic considerations such as operating within given nominal joint positions or low energy motions can also be exploited to improve system stability while being deployed in specific domains such as security, rescue, etc. Simulation results of the proposed optimised motion planner for an iRobot Explorer tracked vehicle are presented. They are also compared with a non-optimised planners to show the validity of the approach.

This paper describes the interface design of our AeSon (Aesthetic Sonification) Toolkit motivated by user-centred customisation of the aesthetic representation and scope of the data. The interface design is developed from 3 premises that distinguish our approach from more ubiquitous sonification methodologies. Firstly, we prioritise interaction both from the perspective of changing scale, scope and presentation of the data and the user's ability to reconfigure spatial panning, modality, pitch distribution, critical thresholds and granularity of data examined. The user, for the majority of parameters, determines their own listening experience for real-time data sonification, even to the extent that the interface can be used for live data-driven performance, as well as traditional information analysis and examination. Secondly, we have explored the theories of Tufte, Fry and other visualization and information design experts to find ways in which principles that are successful in the field of information visualization may be translated to the domain of sonification. Thirdly, we prioritise aesthetic variables and controls in the interface, derived from musical practice, aesthetics in information design and responses to experimental user evaluations to inform the design of the sounds and display. In addition to using notions of meter, beat, key or modality and emphasis drawn from music, we draw on our experiments that evaluated the effects of spatial separation in multivariate data presentations.

This paper evaluates security issues of the recently designed and implemented next generation protocol UDTv4 and offers two contributions to this area of research. Firstly, since UDT is a relatively new protocol, its security requirements have not been considered and explored. An examination investigating its security requirements in implementation is performed. The objective is to achieve a wide class of security methods used on existing mature protocols such as TCP and UDP, and other developed variants such as DCCP and STCP. This will assist investigators, designers, and users who consider and incorporate security when implementing UDT. Secondly, it aims to provide ways of securing applications and traffic using UDT protocol as well as making recommendations for adequate methods to address its security requirements. This will highlight UDT's security limitations and determine the threshold of feasible security schemes within the constraints under which UDT was designed and developed.

Distillation is one of the oldest and most common methods for the purification of liquids. It has been used for centuries to concentrate dilute alcoholic beverages and to obtain perfumes from fruits and flowers. In this paper various methods of distillation, operating principles, equipment for distillation are discussed in detail. Various design and operating policies for binary distillation columns are discussed with objective of maximizing production rate. Significant increasing in capacity can be realized by optimum design of column-i.e. number of trays, trays hold up, reflux drum hold up etc and optimum operation- i.e. reflux ratio and start up procedure. Equipment and column size issues discussed here may be useful to practicing engineers in early stage of distillation design. Some issues in the design and operation of a batch and continuous distillation column are addressed.

The conditions for maximum power transfer from a source antenna to a receiving antenna are examined when the two antennas are in close proximity. As an example, computed and measured results are described for the power transfer efficiency for two-element Yagi antennas. These results can be used to design matching networks between the antenna and a load such as a voltage multiplier for power transfer in a wireless sensor network. It is concluded that maximum PTE could be obtained by continuously tuning the antenna and matching network as the antenna separation and load conditions change. ©2009 IEEE.

Problem-solving methods (PSM) are abstract structures that describe specific reasoning processes employed to solve a set of similar problems. We envisage that off-the-shelf PSMs can assist in the development of agent-oriented solutions, not only as reusable and extensible components that software engineers employ for designing agent architecture solutions, but just as importantly as a set of runtime capabilities that agents themselves dynamically employ in order to solve problems. This chapter describes PSMs for agent-oriented software engineering (AOSE) that address interaction-dependent problem-solving such as negotiation or cooperation.

This paper presents a single, integrated urban model that focuses on the key areas of transport, domestic energy-use, and domestic water use and how these relate to urban planning and other policies. The model structure is spatial ï½ requiring a sub-division of the urban region into disjoint sub-regions. Such a sub-division is necessary, not only because spatial information is essential to any transport model, but also because climatic and demographic factors are common to all resource models, and are spatially heterogeneous. The model is intended for use by local, regional, and state authorities, government departments, energy, and utility service companies as a modelling and decision support tool for analysing the impact on cities of a range of energy, water, transport, and land use related policies. In particular, it seeks to understand the impact - reductions possible at household and city scales. Growing awareness of the threats from climate change has focused attention on greenhouse gas (GHG) emissions and the need to reduce them. Using a sample analysis of Sydney, our on-going research collaboration seeks to examine the working relationships between multiple infrastructure sectors through a single analysis platform. The need to integrate policy for multiple infrastructures is critical given the multiple fronts on which the sustainability of urban systems are now jeopardised.

This paper discusses the issue of ethics when it comes to trialling m-health applications in a hospital environment in Australia. Our team has developed a personalised health monitoring application for smart phones using wireless biosensors to monitor and instruct patients. This paper discusses some of the Australian guidelines regarding ethical aspects of running technological trials of such mobile health projects on cardiac patients. Ethical issues regarding mobile health projects can be generally divided in two parts. The first one concerns any potential dangers to the patient's health. Although testing can also be done on healthy test subjects, the best way to acquire real-life test-data is to perform tests on actual cardiac patients. The second one is the privacy aspect in the doctor-patient relationship as some patients do not want to be identified as having a disease or do not want to have their records kept on file and used in scientific publications. Nevertheless, to show the benefits of this personalized m-health monitoring, a technical trial has to be conducted and research data needs to be published in a verifiable way. This paper gives an introduction into ethical regulations, organizations and issues in Australia. It describes, in detail, the issues involved in conducting technical trials in Australian hospitals. The paper gives several recommendations on how to deal with ethics in personalised m-health monitoring projects. © 2009 IADIS.

This paper presents a new paradigm for viewing the work of Wireless Sensor Networks. The Observed Field (OF) is described as a multi-dimensional Information Space (ISp). The Wireless Sensor Network is described as a Transformation Space (TS), while the information collector is a single point consumer of information, described as an Information Sink (ISi). Formal mathematical descriptions are suggested for the OF and the ISp. Mathematical descriptions for the TS and the ISi, based on the notion of Path Mutual Information, are proposed. Information flows from ISp to ISi via TS. TS can be formally thought of as a multi-dimensional transform function between ISp and ISi. It can be aggregated into a notional multidimensional value. This formal mathematical description can be used to create numerical optimization routines for generating TSs, against cost functions such as power consumption, and constraints such as maximum distance between sensors.

Quantum computing represents the prodigiously fertile union of quantum physics with the theory of computation and especially issues of computational complexity. It is known that quantum processes can offer solutions to some information processing tasks that are exponentially more efficient than any known classical methods. Perhaps the most celebrated example is Shor's 1994 quantum algorithm for integer factorisation. In recent years there has been a surge of activity in our understanding of quantum computational power and its prospective applicability and limitations. A variety of problems in diverse areas of mathematics, has been identified (so-called BQP-complete problems) that have efficient quantum algorithms and also embody the full power of efficient quantum computation. In quantum many body physics (including study of quantum circuits, of local hamiltonians, and of further formalisms such as measurement based computing) some problems have been shown, surprisingly, to admit efficient classical solution while others (e.g. certain ground state properties of local hamiltonians) are likely to be computationally intractible, having been shown to be so-called QMA-complete. Quantum entanglement is often regarded as an essential ingredient in these considerations and there has been considerable development in understanding its scaling behaviour in many body systems. This conference is devoted to recent theoretical developments in these areas and related issues. Invited speakers will be requested to include overview material (in addition to recent research) with the aim of making the essential ideas of these important developments accessible to a broader audience of QIP researchers.

Corrosion is the primary cause of failure in steel bridges. Stripping of rust and deteriorated paint and then repainting the steel are the procedures in steel bridge maintenance, and is one of the biggest expenditure items in bridge maintenance activities. Grit-blasting, which is an effective and efficient method of paint stripping, is extremely labour intensive and hazardous. Workers have to not only spend long periods of time handling forces of 100N and above, but also need to take precautions to avoid exposure to the dust containing hazardous materials and chemicals. Thus supplementing manual labour in grit-blasting with robotic aids has a significant health, safety and economic impact.

The growth of energy need - especially of new consumers like China and India -, the uncertainty in fuel prices and the scarcity of use of renewable sources pave the way to the emerging role of energy efficiency as a competitive advantage in a globalised market. Unfortunately small & medium enterprises (SMEs), the large majority of firms in a country, generally do not have a high operational energy efficiency, since they are characterized mainly by scarcely standardized operations and cannot afford too expensive energy audits and management programs. This paper aims at introducing an innovative framework that has been developed to achieve the operational energy efficiency of SMEs. Firstly, through an accurate breakdown of the firm into functional units, the main consuming areas are identified so that a criticality index can be defined; secondly, an enhancement index highlights the gap of each unit towards the best available techniques/practices (BAT/Ps) in energy management programs. Finally, a synthetic index (priority index) created by the junction of the two previous indexes, points out the most profitable areas in which energy saving actions should be implemented. The methodology, particularly quick and simple, has been successfully tested in 25 SMEs in Northern Italy.

In this paper, we present a study in understanding sensing error's impact on traffic signal control performance. Adaptive traffic signal control systems depend on information from traffic sensors to interpret the state of traffic. Signal timings are adjusted at real time according to the state of traffic. Queue length is an important element of the state of traffic, and errors in estimating queue length influences control decision and hence the performance. This paper presents the first attempt to quantify the effects of sensing error on control performance in the field of traffic control. A novel technique to estimate queue length using data from single loop detector is presented, and estimations are compared with parallel observations. The results show that moderate overestimation of queue length may significantly improve control performance. The benefit from overestimation suggests including arriving traffic in system state, and using look-ahead algorithms to calculate signal timings. Copyright © 2009 ACM.

Agent mining, namely the interaction and integration of multi-agent and data mining, has emerged as a very promising research area. While many mutual issues exist in both multi-agent and data mining areas, most of them can be described in terms of or related to ubiquitous intelligence. It is certainly very important to define, specify, represent, analyze and utilize ubiquitous intelligence in agents, data mining, and agent mining. This paper presents a novel but preliminary investigation of ubiquitous intelligence in these areas. We specify five types of ubiquitous intelligence: data intelligence, human intelligence, domain intelligence, network and web intelligence, organizational intelligence, and social intelligence. We define and illustrate them, and discuss techniques for involving them into agents, data mining, and agent mining for complex problem-solving. Further investigation on involving and synthesizing ubiquitous intelligence into agents, data mining, and agent mining will lead to a disciplinary upgrade from methodological, technical and practical perspectives.

Using a Neonatal Intensive Care Unit (NICU) case study, this work investigates the current CRoss Industry Standard Process for Data Mining (CRISP-DM) approach for modeling Intelligent Data Analysis (IDA)-based systems that perform temporal data mining (TDM). The case study highlights the need for an extended CRISP-DM approach when modeling clinical systems applying Data Mining (DM) and Temporal Abstraction (TA). As the number of such integrated TA/DM systems continues to grow, this limitation becomes significant and motivated our proposal of an extended CRISP-DM methodology to support TDM, known as CRISP-TDM. This approach supports clinical investigations on multi-dimensional time series data. This research paper has three key objectives: 1) Present a summary of the extended CRISP-TDM methodology; 2) Demonstrate the applicability of the proposed model to the NICU data, focusing on the challenges associated with multi-dimensional time series data; and 3) Describe the proposed IDA architecture for applying integrated TDM. ©2009 IEEE.

This paper discusses a methodology to manage wireless sensor networks (WSN) with self-organising feature maps, using co-operative Extended Kohonen Maps (EKMs). EKMs have been successfully demonstrated in other machine-learning contexts such as learning sensori-motor control and feedback tasks. Through a quantitative analysis of the algorithmic process, an indirect-mapping EKM can self-organise from a given input space, such as theWSNs external factors, to administer theWSNs routing and clustering functions with a control parameter space. Preliminary results demonstrate indirect mapping with EKMs provide an economical control and feedback mechanism by operating in a continuous sensory control space when compared with direct mapping techniques. By training the control parameter, a faster convergence is made with processes such as the recursive least squares method. The management of a WSNs clustering and routing procedures are enhanced by the co-operation of multiple self-organising EKMs to adapt to actively changing conditions in the environment.

This paper proposes a genetic algorithm (GA) based beamformer to optimize speech recognition accuracy for a pretrained speech recognizer. The proposed beamformer is designed to tackle the non-differentiable and non-linear natures of speech recognition by employing the GA algorithm to search for the optimal beamformer weights. Specifically, a population of beamformer weights is reproduced by crossover and mutation until the optimal beamformer weights are obtained. Results show that the speech recognition accuracies can be greatly improved even in noisy environments.

Over the past few years a dramatic increase in the use of Social networking websites, to the point in which it is considered unusually to not be part of one (or more) of them. Rather than attempt to explore a very specific section of social networking websites, I chose to look at some of the issues which have received some review over the past few years, and highlight some of the communication issues that result from the increased use of these websites. For this study, MySpace, Facebook and Friendster have been considered. Importance has been given to areas such as impression management, user profile, disclosure of personal information and role of these sites during the time of crisis. The paper suggests future areas of research.

Ranking is a main research issue in IR-styled keyword search over a set of documents. In this paper, we study a new keyword search problem, called context-sensitive document ranking, which is to rank documents with an additional context that provides additional information about the application domain where the documents are to be searched and ranked. The work is motivated by the fact that additional information associated with the documents can possibly assist users to find more relevant documents when they are unable to find the needed documents from the documents alone. In this paper, a context is a multi-attribute graph, which can represent any information maintained in a relational database. The context-sensitive ranking is related to several research issues, how to score documents, how to evaluate the additional information obtained in the context that may contribute the document ranking, how to rank the documents by combining the scores/costs from the documents and the context. More importantly, the relationships between documents and the information stored in a relational database may be uncertain, because they are from different data sources and the relationships are determined systematically using similarity match which causes uncertainty. In this paper, we concentrate ourselves on these research issues, and provide our solution on how to rank the documents in a context where there exist uncertainty between the documents and the context. We confirm the effectiveness of our approaches by conducting extensive experimental studies using real datasets. Copyright 2009 ACM.

Twig queries have been extensively studied as a major fragment of XPATH queries to query XML data. In this paper, we study PXML-RANK query, (Q, k), which is to rank top-k probabilities of the answers of a twig query Q in probabilistic XML (PXML) data. A new research issue is how to compute top-k probabilities of answers of a twig query Q in PXML in the presence of containment (ancestor/descendant) relationships. In the presence of the ancestor/descendant relationships, the existing dynamic programming approaches to rank top-k probabilities over a set of tuples cannot be directly applied, because any node/edge in PXML may have impacts on the top-k probabilities of answers. We propose new algorithms to compute PXML-RANK queries efficiently and give conditions under which a PXML-RANK query can be processed efficiently without enumeration of all the possible worlds. We conduct extensive performance studies using both real and large benchmark datasets, and confirm the efficiency of our algorithms. Copyright 2009 ACM.

In this paper, we study the problem of continuous monitoring of reverse k nearest neighbor queries. Existing continuous reverse nearest neighbor monitoring techniques are sensitive towards objects and queries movement. For example, the results of a query are to be recomputed whenever the query changes its location. We present a framework for continuous reverse k nearest neighbor queries by assigning each object and query with a rectangular safe region such that the expensive recomputation is not required as long as the query and objects remain in their respective safe regions. This significantly improves the computation cost. As a by-product, our framework also reduces the communication cost in client-server architectures because an object does not report its location to the server unless it leaves its safe region or the server sends a location update request. We also conduct a rigid cost analysis to guide an effective selection of such rectangular safe regions. The extensive experiments demonstrate that our techniques outperform the existing techniques by an order of magnitude in terms of computation cost and communication cost. © 2009 VLDB Endowment.

One common predictive modeling challenge occurs in text mining problems is that the training data and the operational (testing) data are drawn from different underlying distributions. This poses a great difficulty for many statistical learning methods. However, when the distribution in the source domain and the target domain are not identical but related, there may exist a shared concept space to preserve the relation. Consequently a good feature representation can encode this concept space and minimize the distribution gap. To formalize this intuition, we propose a domain adaptation method that parameterizes this concept space by linear transformation under which we explicitly minimize the distribution difference between the source domain with sufficient labeled data and target domains with only unlabeled data, while at the same time minimizing the empirical loss on the labeled data in the source domain. Another characteristic of our method is its capability for considering multiple classes and their interactions simultaneously. We have conducted extensive experiments on two common text mining problems, namely, information extraction and document classification to demonstrate the effectiveness of our proposed method

In this paper, we apply an evolutionary optimization classifier, referred to as genetic algorithm-based multiple classifier (GaMC), to the long-range contacts prediction. As a result, about 44.1% contacts between long-range residues (with a sequence separation of at least 24 amino acids) are founded around the sequence profile (SP) centre when evaluating the top L/5 (L is the sequence length of protein) classified contacts if the SP centers are known. Meanwhile, with the knowledge of sequence profile center and the GaMC method, about 20.42% long-range contacts are correctly predicted. Results showed that SP center may be a sound pathway to predict contact map in protein structures. ©2009 IEEE.

View description>>

Multiparty meetings common to many business environments often have participants who are generally stationary. Hence, active speakers can be disambiguated by location, and meeting analysis research groups have proposed the use of speaker location information (spatial cues) for meeting segmentation and higher level analysis. As the cues are estimated from multi-microphone recordings, this paper studies the effect of varying microphone directivity patterns on the spatial cue accuracy and reliability. Results from theoretical simulations and recordings from a real reverberant environment suggest that different spatial cues (based on inter-microphone signal time delays or amplitude level differences) optimally respond to different microphone directivity patterns, where time delay accuracy was found to be independent of the relative microphone configuration. © EURASIP, 2009.

Smoke detection in video surveillance images has been studied for years. However, given an image in open or large spaces with typical smoke and the disturbance of commonly moving objects such as pedestrians or vehicles, robust and efficient smoke detection is still a challenging problem. In this paper, we present a novel and reliable framework for automatic smoke detection. It exploits three features: edge blurring, the gradual change of energy and the gradual change of chromatic configuration. In order to gain proper generalization ability with respect to sparse training samples, the three features are combined using a support vector machine based classifier. This system has been run more than 6 hours in various conditions to verify the reliability of fire safety in the real world.

This paper studies a multi-objective instance of the berth allocation problem (BAP). The BAP involves the determination of exact berthing times and positions of incoming ships in a container port so as to minimize concurrently the three objectives of makespan of the port, total waiting time of the ships, and degree of deviation from a predetermined service priority schedule. These objectives represent the interests of both port and ship operators. Unlike most existing approaches in the literature which are singleobjective- based, a multi-objective evolutionary algorithm (MOEA) that incorporates the concept of Pareto optimality is proposed for solving the multi-objective BAP. The multiobjective approach reveals several interesting characteristics of the BAP.

This paper describes the design of a scalable bio-mimetic framework in the management domain of complex Ubiquitous Service-Oriented Networks. An autonomous network service management platform - SwarmingNet is proposed. In this SwarmingNet architecture, the required network service processes are implemented by a group of highly diverse and autonomic objects. These objects are called TeleService Solons as elements of TeleService Holons, analogue to individual insects as particles of the whole colony.

When a large robot manipulator is remotely controlled by means of a small haptic device, there are two issues which should be addressed: mapping of robot arm workspace and haptic device workspace, and accurate and safe control of the movement of the robot arm. This paper presents a haptic device workspace spanning control method for haptic-based teleoperation. The spanning control method includes haptic-space scaling control, drift control and edge motion control. A force control algorithm is also presented to control the robot arm's motion in complex 3D environments. Experimental results demonstrate that the mapping method and the force control algorithm can remotely control a robot arm to rapidly reach target positions, minimize the oscillation of the haptic device handle, achieve accurate positioning and provide the operator with efficient touch sensing. © 2009 IEEE.

Seismic stability of tailings dams and embankments is an important topic which needs the special assessments by the researchers as it is mainly governed by the safety concerns. Several researchers in the past had attempted to investigate the seismic stability of earthen dams and embankments by using conventional pseudo-static method of analysis. However, the crude estimate of finding the approximate seismic acceleration makes the pseudo-static approach too conservative to adopt in the stability assessment. Although a few researchers in the recent past highlighted the limitations and drawbacks of the pseudo-static approach, there are very limited studies being reported worldwide for the seismic stability assessment of earthen dams and embankments by using alternative methods of analysis. In this paper, a recently developed and modified pseudo-dynamic method of analysis is used to compute the seismic inertia forces acting on the sliding wedge of the tailings dam by considering the effects of time of seismic accelerations, phase differences in the propagating shear and primary waves in the soil during an earthquake, frequency of earthquake excitation etc. with the horizontal and vertical seismic accelerations. The factor of safety decreases with increase in the seismic accelerations and phase difference in body waves. Influence of various parameters such as seismic acceleration coefficients, period of lateral shaking on seismic stability of tailings dam are studied under harmonic seismic loading conditions for both empty and full water cases. Present results are compared with the pseudo-static based solutions to validate the findings of the pseudo-dynamic method of analysis. © 2009 IOS Press.

Rail tracks are often placed on ballast which offers the desirable resiliency to cyclic loads. However ballasted beds need periodic maintenance due to deformation and degradation associated with breakage and fouling. A proper understanding of load transfer mechanisms and their effect on ballast breakage are prerequisites for minimizing maintenance costs. Recycled ballast is a cheaper and environmentally viable option but its strength characteristics need to be investigated beforehand. This paper demonstrates the analytical, numerical and laboratory investigations carried out to investigate the geotechnical behavior of ballast, including shear strength, ballast breakage, and confining pressure. The potential use of geosynthetics for improving the stability and drainage of railway tracks under high monotonic and cyclic loading is also studied. Field tests were carried out to measure the in-situ stresses of ballast on a section of instrumented track funded and built by RailCorp, Australia. © 2009 Taylor & Francis Group, London.

We develop the theory of entanglement-assisted quantum error correcting codes (EAQECCs), a generalization of the stabilizer formalism to the setting in which the sender and receiver have access to pre-shared entanglement. Conventional stabilizer codes are equivalent to self-orthogonal symplectic codes. In contrast, EAQECCs do not require self-orthogonality, which greatly simplifies their construction. We show how any classical quaternary block code can be made into a EAQECC. Furthermore, the error-correcting power of the quantum codes follows directly from the power of the classical codes.

Climate change is one of the most pressing issues facing Australia today. This is a challenge and responsibility that is shared by all Australian households. Improvements to energy and water efficiency of houses can significantly cut greenhouse gas emissions and reduce utility bills. In July 2004 the New South Wales (NSW) government introduced the Building Sustainability Index (BASIX) to assess potential performance of a dwelling against a set of pre-determined criteria. Housing construction in NSW is the first in Australia to be subjected to mandatory sustainability requirements. BASIX is an online assessment tool which sets scores required to obtain development approval in new residential projects. BASIX is mandated only to improve environmental performance of new residential buildings and does not attempt to improve environmental performance of existing housing stocks which continue to consume natural resources and pollute the environment. Existing houses represent approximately 98% of residential building stocks in NSW and any improvement to these dwellings will have a profound impact on reducing the negative effects of the environment. This paper examines the sustainable upgrading strategies in improving environmental performance of three existing single dwellings in meeting the minimum BASIX requirements. This paper presents an economic analysis of sustainable upgrading using Net Present Value. The results suggest that sustainable upgrading of existing housing stocks is feasible and the scheme will be more attractive if the payback period is reduced with further government financial assistance.

Ultra-wideband (UWB) technology has been considered for the physical layer in recently proposed IEEE802.15 standard (TG6) for Wireless Body Area networks. Wireless links covered by this standard will operate in UWB unlicensed band with antennas on implanted devices having small form factors. Except for those installed on-body and on external receivers, the antenna will be operating in-body, surrounded by body tissue. Body tissues have high dielectric constants and are highly dissipative. Once implanted beneath multiple layers of tissue, the device, which is expected to be consuming very low power, experience heavy losses in its transmission and reception path. Therefore, it is essential that antenna losses, both mismatch and resistive, are minimised. In this paper we will demonstrate a method to minimize antenna mismatch losses by loading the antenna with insulating material.

Semantic similarity models are a series of mathematical models for computing semantic similarity values among nodes in a semantic net. In this paper we reveal the paradox in the applications of these semantic similarity models in the field of information retrieval, which is that these models rely on a common prerequisite - the words of a user query must correspond to the nodes of a semantic net. In certain situations, this sort of correspondence can not be carried out, which invalidates the further working of these semantic similarity models. By means of two case studies, we analyze these issues. In addition, we discuss some possible solutions in order to address these issues. Conclusion and future works are drawn in the final section. © 2009 ICST Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.

Service, as a critical object impenetrating every corner of SOE, is a hot research topic in many research domains. Software Engineering (SE), as a subject in engineering field, its researchers pay more attention to supporting advanced technologies for promoting service activities in SOE. In this paper, we draw the position in the research field of semantic service search, service evaluation and ranking in SOE.

Price dispersion of homogeneous goods is widely prevalent in our economy. For instance, on 18 January 2008, around 9pm, two service stations in Roseville, Sydney, that are less than 1 km apart, were selling unleaded fuel at 1.359 and 1.439 Australian dollars per litre. Consumers who have access to the pricing information can benefit economically (e.g., a 5.5% saving in the above scenario). Several websites such as GasBuddy,motormouth1 enable consumers to compare fuel prices. However, the fuel price information is collected manually, by volunteers or employees, which is cumbersome, error-prone and not up-to-date. In this demo, we will demonstrate the operation of our PetrolWatch system [2], [3], which automatically collects fuel prices using camera phones. This is the first instance of applying participatory sensing [1] in sharing consumer pricing information.

In human's expression recognition, the representation of expression features is essential for the recognition accuracy. In this work we propose a novel approach for extracting expression dynamic features from facial expression videos. Rather than utilising statistical models e.g. Hidden Markov Model (HMM), our approach integrates expression dynamic features into a static image, the Histogram Variances Face (HVF), by fusing histogram variances among the frames in a video. The HVFs can be automatically obtained from videos with different frame rates and immune to illumination interference. In our experiments, for the videos picturing the same facial expression, e.g., surprise, happy and sadness etc., their corresponding HVFs are similar, even though the performers and frame rates are different. Therefore the static facial recognition approaches can be utilised for the dynamic expression recognition. We have applied this approach on the well-known Cohn-Kanade AU-Coded Facial Expression database then classified HVFs using PCA and Support Vector Machine (SVMs), and found the accuracy of HVFs classification is very encouraging. © 2009 IEEE.

We propose a multiple source domain adaptation method, referred to as Domain Adaptation Machine (DAM), to learn a robust decision function (referred to as target classifier) for label prediction of patterns from the target domain by leveraging a set of pre-computed classifiers (referred to as auxiliary/source classifiers) independently learned with the labeled patterns from multiple source domains. We introduce a new data-dependent regularizer based on smoothness assumption into Least-Squares SVM (LS-SVM), which enforces that the target classifier shares similar decision values with the auxiliary classifiers from relevant source domains on the unlabeled patterns of the target domain. In addition, we employ a sparsity regularizer to learn a sparse target classifier. Comprehensive experiments on the challenging TRECVID 2005 corpus demonstrate that DAM outperforms the existing multiple source domain adaptation methods for video concept detection in terms of effectiveness and efficiency.

This paper reports on an ethnographic study of mobile phone adoption and use in a remote Aboriginal community in Cape York, Australia. The researchers found that, within nine months of the introduction of the 3G network, 58% of the Indigenous people interviewed had acquired a mobile phone, a much higher rate of adoption than any other ICT. The phones were employed for communication, with multimedia uses (music, games, videos, photos) also very popular. Issues included the cost, robustness and usability of the devices, although most people managed costs well by purchasing pre-paid phones. The findings suggest a number of possible initiatives that government, service providers and business could consider to leverage mobile phone usage and develop capacity in the community.

A set of experiments varying the MTMS:TEOS ratio were prepared in acid medium and characterized. A textural, physico-chemical, mechanical, and electrical characterization of this series of experiments is presented.

Current telecommunication network management systems rely extensively on human intervention. They are also prone to fundamental changes as the managed network evolves. These two attributes, combined with the growing complexity of networks and services, make the cost of network management very high. In recent years, we have witnessed the emergence of artificial intelligence applications. Some are aimed at the creation of autonomic network management systems. This paper offers a novel approach to the design of a network management system that incorporates intelligent agents. As a benchmark to this model, we use two approaches most widely in use in network management systems today. The focus of this paper is on synchronization issues, service discovery and policy enforcement.

Trust is widely acknowledged as being important for the efficient and effective operation of business in virtual environments. This is because trust functions like a glue that holds and links virtual agents together as they relate and collaborate remotely. In virtual environments, trust needs to be established swiftly as there is little time to build it gradually in the absence of face-to-face meetings. However, the manner in which trust develops and is maintained is a critical factor in relationships, both physically and virtually. In virtual environments, trust needs to be managed including network connection as well as social aspects of interaction. Maintaining trust in virtual environments is defined as an effort to maximize the benefits of such virtual relationship and to prevent the level of trust from decreasing. In this paper, we undertake a general survey of the current situation of trust maintenance in virtual environments. We review several researches from the perspective of terminology, strategies presented, and types of strategies. We describe the benefits and shortcomings of each strategy, conduct an integrative review of these strategic approaches, and make suggestions for future research. © 2010 ACM.

Wireless Body Area Networks (WBANs) enable placement of tiny biomedical sensors on or inside the human body to monitor vital body signs. The IEEE 802.15.6 task group is developing a standard to optimize WBAN performance by defining the physical layer (PHY) and media access control (MAC) layer specifications. In this paper an energy efficient MAC protocol (BodyMAC) is proposed. It uses flexible bandwidth allocation to improve node energy efficiency by reducing the possibility of packet collisions and by reducing radio transmission times, idle listening and control packets overhead. BodyMAC is based on a Downlink and Uplink scheme in which the Contention Free Part in the Uplink subframe is completely collision free. Three types of bandwidth allocation mechanisms allow for flexible and efficient data and control communications. An efficient Sleep Mode is introduced to reduce the idle listening duration, especially for low duty cycle nodes in the network. Simulation results show superior performance of BodyMAC compared to that of the IEEE 802.15.4 MAC. ©2009 IEEE.

The interface enables the performer to use the interface as an instrument for iterative interpretations and variations of sonifications of multiple datastreams. Using the interface, the performer can alter the scale, granularity, timbre, hierarchy of elements, spatialisation, spectral filtering, key/modality, rhythmic distribution and register ‘on-the-fly’ to both perform data-generated music, and investigate data in a live exploratory, interactive manner.

Service composition methods range from industry standard approaches based on Web Services and BPEL to Semantic Web approaches that rely on AI techniques to automate service discovery and composition. Service composition research mostly focuses on the dynamic (workflow) aspects of compositions. In this paper we consider the static component of service composition and discuss the importance of compatibility of service interfaces in ensuring the composability of services. Using a flight booking scenario example we show that reducing the granularity of services by decomposition into service operations with normalized interfaces produces compatible interfaces that facilitate service assembly. We then show how relational algebra can be used to represent service operations and provide a framework for service assembly.

While most business applications typically operate on structured data that can be effectively managed using relational databases, some applications use more complex semistructured data that lacks a stable schema. XML techniques are available for the management of semistructured data, but such techniques tend to be ineffective when applied to large amounts of heterogeneous data, in particular in applications with complex query requirements. In this paper we describe an approach that relies on the mapping of multiple semistructured data sets to objectrelational structures and uses an object-relational database to support complex query requirements. We illustrate this approach using weakly heterogeneous oceanographic data.

Wide adoption of SOA (Service-Oriented Architecture) by the industry and the growing number of large-scale Web Services projects have created an urgent need for research community and industry practitioners to develop comprehensive methodologies that support the entire SDLC (Software Development Lifecycle) of service-oriented applications. To ensure that resulting services are stable, reusable and extendable, such methodologies must be based on sound engineering principles and guide developers through the analysis, design, implementation and deployment phases of the service-oriented SDLC. © 2009 Springer Berlin Heidelberg.

Corporate entrepreneurship is the implementation of a value creation process in an organizational setting. Consistent with the Schumpeterian understanding of entrepreneurship, a "new combination" that should directly affect the performance of the firm is formed; and the process of forming this new combination manifests itself as an outcome of a complex social mechanism affected by internal and external factors. However, in spite of the biasing anecdotal evidence, conventional wisdom, and tendency in favor of entrepreneurship, a "black box" between firm-level entrepreneurship and performance has pervaded the relationship. Nevertheless, the model proposed in this study brings a new and distinguishing line of sight into the firm-level entrepreneurship literature: rather than being an equivalent, the entrepreneurial orientation construct is treated as an antecedent of corporate entrepreneurship; moreover the behavioral construct of corporate entrepreneurship is placed in between this strategic posture and performance, to complete "the missing" link between firm-level entrepreneurship and performance. It is proposed that this formulation of roles and meanings attached to both terms, leads to a solid, conclusive, and systematic direct positive relationship between firm level entrepreneurship and performance. Empirical findings confirm this proposal, making this formulation the most important contribution of this study to the firm level entrepreneurship literature. © 2009 PICMET.

This article deals with the long term performance of reinforced concrete elements aged in chloride environment. The analysis of the initiation phase of corrosion show that for a same concrete an increase of concrete cover is not sufficient to delay the onset of corrosion. The analysis of the serviceability of reinforced concrete members allows to highlight two different behaviours during the propagation phase: The first phase points out a decrease of the stiffness of reinforced concrete element due to the decrease of bond between rebars and this phase is followed by a stabilisation of stiffness when the bond is totally loss; then the corrosion process could continue without external sign or warnings. The analysis of the load-bearing capacity after 14 and 23 years allows to understand the relationship between the ultimate load and the steel cross-section reduction due to corrosion. Regarding the structural performance reduction, results have shown that the propagation period can be as long as the initiation phase in the service life. Therefore, the propagation period should be considered as a normal step in the service life.

Parallel dimming for reducing the intensity of High Power Light-Emitting Diode (HP-LED) is an effective way of achieving high contrast ratio and wide dimming range. However the scheme has limitation due to response of control loop and higher power dissipation due to losses during turn-off period. Therefore shorting-inductor approach is proposed in this paper which is capable of achieving improvement in efficiency while keeping similar level of performance. Moreover the proposed strategy for dimming HP-LED is considered to be more flexible in its design. For example the converter can provide dimming feature even if controller is not used to keep track of inductor current. This indicates performance of the method is assured with different types of control strategy which implies wider deployment in different applications.

The IEEE 802.11 Distributed Coordination Function (DCF) Medium Access Control (MAC) protocol continues to suffer from throughput degradation when directly applied in multi-hop Wireless Mesh Network (WMN). The Request-to-Send/Clear-to-Send (RTS/CTS) signaling partially solved hidden node problems however the exposed node problems remain unaddressed. The IEEE 802.11 MAC does not allow the exposed nodes to initiates its transmission for the entire duration of ongoing transmission over multi-hop network leads to throughput degradation. Moreover, the amount of needed signaling packets takes place at every hop reduces the overall multi-hop throughput significantly. This project proposes a set of enhancement to the existing IEEE 802.11 DCF MAC by enabling concurrent transmission by the exposed nodes and reduces the amount of signaling packets (CMAC-SS) required at every hop until the data packet reaches its destination. Analytical models are developed and simulated over quasi-static Rayleigh fading channel. The multi-hop network performances are evaluated in terms of throughput and delay. The CMAC-SS protocol outperforms the existing IEEE DCF MAC with more than 14% increase in overall throughput of multi-hop WMN. ©2009 IEEE.

In a bilevel decision problem, decision making may involve multiple followers and fuzzy demands. This research focuses on the problem of fuzzy linear bilevel decision making with multiple followers who share common constraints (FBCSF). Based on the ranking relationship among fuzzy sets defined by cut set and satisfactory degree α, a FBCSF model is presented and a particle swarm optimization based algorithm is developed. The experiments reveal that solutions obtained by this algorithm are reasonable and stable. Copyright 2009 ACM.

Due to rapid technological innovation and severe competition, the upstream component price and the downstream product cost in hi-tech industries usually decline significantly with time. In building a pricing supply chain model, some coefficients are generally obtained from experiments and cannot be defined as crisp numbers. Thus, an effective fuzzy pricing supply chain model becomes crucial. This paper establishes a fuzzy bi-level pricing model for buyers and vendors in supply chains. Then, a particle swarm optimization (PSO) based algorithm is developed to solve problems defined by this model. Experiments show that this PSO-based algorithm can solve fuzzy bi-level pricing problems effectively.

This paper describes a personalised rehabilitation application using a smart phone (PDA) and wireless (bio) sensors. It instructs and motivates patients to follow their exercise programme and keeps track of their progress. It also monitors the relevant biosignals and provides immediate feedback to the patient. Sensors transmit data to the mobile phone where it is analysed locally and the data can also be instantaneously transmitted to a healthcare centre for remote monitoring by a health professional. The rehabilitation application is personalised for each cardiac patient and provides tailored advice (e.g. exercise more, slow down). A trial with a rehabilitation centre is in progress in which we investigate whether the personalised rehabilitation application improves the success of the rehabilitation programme in terms of patient compliance with recommended life style changes (such as increase physical activity or lose weight) and whether use of the system brings peace of mind to cardiac patients.

In 2009, the Australian government has formulated strategies to provide $3.9 billion Energy Efficient Home Package for cutting energy waster and $12.9 billion Water for the Future plan for reducing the use of drinking water, aim of tackling climate change and reducing green house emission. Under the strategies, there are incentive schemes for households of the existing homes, which include a) rebates of up to $500 for installing a new rainwater tank or a permanent grey water treatment system; b) offers of up to $1,600 ceiling insulation or installation of solar hot water system or an assistance of up to $1,000 installing insulation in private rental properties; c) cash rebates of up to $8,000 for the installation of solar photovoltaic systems on homes; and d) providing detailed, quality household sustainability assessments and green renovations packs to Australian households as well as access to low interest Green Loans of up to $10,000 each to make existing homes more energy and water efficient. This paper studies whether the incentive schemes motivate households and how much attraction of the schemes for households. The paper starts to review government policies for home energy efficient and water reduction programs in Australia and compare schemes provided by other countries. Case studies on incomes and expenses for a standard family, costs and benefits, as well as elements impact on households of taking the government incentive schemes are examined. The paper comments on the current incentive programs provided by the government and argue that education on attitude toward saving electricity and water should be one of the important parts of the programs.

The Australian Government has recently announced a Renewable Energy Target (RET) scheme to provide up front payments of $8,000 for around 25,250 households of income less than $100,000 per year installing a 150 watt solar panel system starting on 01 July 2009 using $202 million taxpayers money. The scheme has not included households income greater than $100,000, nor for developers who produce new houses. Whether the policies are effective and sustainable are arguable. This paper examines policies designed to encourage households to install solar panel system in Australia and demonstrates reasons for supporting developers to build green houses using Net Present Value (NPV) rule in a case study. The findings suggest that the government should support installation of solar systems in both households and the developers.

Both reside above a ground plane, and is excited by a coaxial probe. Unlike in previous designs that have a dielectric resonator of a lower permittivity above one or more thin segments of higher permittivity, the top dielectric resonator in this antenna has a higher permittivity than the lower segment.

An extremely compact ultrawideband (UWB) dielectric resonator antenna is presented for potential use in compact UWB wireless communication devices. The antenna consists of a dielectric resonator of relatively high permitted attached to a thin dielectric segment of relatively low permittivity, positioned on a ground plane. The current version is fed by a coaxial probe although other feeding methods are possible. The use of two dielectrics and multiple resonance modes have helped this design to cover the entire FCC UWB band (3.1 - 10.6 GHz, 1:3.4 or 109.5% bandwidth) in a very small volume. The antenna size has been further reduced, without compromising the bandwidth, by removing about half of the dielectric volume and applying a metal coating on one side of the dielectrics. © 2009 EuMA.

With the development of Cognitive Radio networks, in order to fully utilize the scarce spectrum resources, secondary users are capable of exploiting the available spectrum of primary users. However, when there are several spectrum options available, how to select an appropriate one for the secondary user according to the spectrum quality and the QoS requirements of different kinds of applications is a new challenge. In this paper, we propose a new Automatic Distributed Spectrum Decision (ADSD) method to solve this problem. ADSD considers multiple characterization parameters, in particular, the primary users' arrival probability, to estimate the quality of the available spectrum options. A weight self-generation mechanism is included to automatically determine the weights of different parameters, thus avoiding the difficulty and irrationality when relying on the users to specify the weights directly. In addition, in conjunction with the reconfiguration mechanism, ADSD can reduce the rate of spectrum handoffs by reconfiguring the transmission parameters rather than making a new decision for the existing transmission. Simulation results show that without any users' interference, ADSD can automatically select the appropriate spectrum for transmission and significantly improve the Cognitive Radio network performance in terms of throughput and the spectrum handoff rate. ©2009 IEEE.

These mashup applications are characterized by rapid development using existing data sources and the use of new technologies such as AJAX, JSON, etc. Developers often focus on delivering rich functionality via the browser environment and pay little attention to the design and maintainability of the applications. In this paper we describe our experience in developing an Itinerary Planner travel application, and discuss the challenges associated with developing mashups. In the conclusion, we briefly discuss the lessons learned in addressing these challenges and how these lessons can be applied to future mashup projects.

An automated auction is an efficient market institution for real-world trading of commodities. This paper presents a novel fuzzy bidding strategy (FAA-Bid), which employs assessments of multiple attributes of items as well as agents' attitude on bidding item to procure an item in automated auction. The assessment of attributes adapts the fuzzy sets technique to handle uncertainty of the bidding process as well use heuristic rules to determine attitude of bidding agents in simulated auctions to procure goods. The overall assessment is used to determine a price range based on current bid, which finally selects the best one as the new bid. © 2010 ACM.

This study tests the 1D/2D coupled modelling approach on its ability to emulate the âroadâ portion of runoff which is conveyed in the kerb/gutter alignment. The event modelled is an approximately 1 in 1 year ARI event in magnitude. Given itâs small ARI it may be supposed that it is mainly comprised of runoff from impervious surfaces (10% roof and 90% road and others). In the event flow from the road moves as sheet flow to the kerb where it is routed to inflow pits. Via the pits it enters the pipe and at the downstream end of the pipe it is gauged. The modelling system is found to be capable of matching the gauged hydrograph for the relatively small event very well. What is also found however is that model parameters that might, in a 1D model, be relatively well informed by field inspection, are instead required to be altered outside recommended ranges in order to optimise the fit between gauged and modelled flow. That is, there is a degree of conceptualisation in the 1D/2D system that was unexpected.

An equivalent electrical circuit is applied to predict the motor characteristics and the computation results show that the proposed LIM drive system is appropriate for driving the HTS maglev transportation prototype.

Parameters such as the winding flux, back electromotive force and inductances are accurately calculated based on a series of numerical field solutions and improved formulations. An equivalent electrical circuit is employed to derive the equation of the external characteristic, the most important performance of the synchronous generator.

Print Request Permissions This paper presents a phase angle control method of coil currents in a zone-control induction heating (ZCIH) system, which has split working coils on a work piece. The ZCIH system controls the amplitude of each coil current to make the temperature distribution on the work piece uniform. The coil currents should be adjusted to be in phase with each other to control the current amplitude in a wide range from 0 to 100%. This paper derives the phase-angle change of the coil current in transient states, and reveals that the phase-angle change can be considered as a first-order response. A phase-angle controller was designed and examined in experiments with a two-zone ZCIH system, making it possible to adjust the current phase angle not only in steady states but also in transient states.

In this paper, we present the design of an integrated CMOS sensor for cell impedance measurement. To achieve simultaneous measurements over a wide frequency range, the impedance sensor has been developed using silicon cochleae as both the input stimulus generator and the output frequency analyzer. This solution, inspired by the accuracy and efficiency of biological systems, has several advantages. The silicon cochlea is able to make measurements over a very wide frequency range (from Hz to MHz) with variable resolution. Power consumption of the sensor is below 30μW due to the biasing regime used in the silicon cochleae. Furthermore, the implementation of the sensor is fully autonomous requiring no reference clocks or signal generators, facilitating integration into larger cell analysis systems. ©2009 IEEE.

The human cochlea is a fascinating transduction organ that illustrates the ingenious way in which engineering problems are solved in nature. A healthy cochlea has a dynamic range in the order of 120 dB; that is, the difference between the roar of the engines of a Boeing 747 and the faintest whisper. We discuss the recent assertion that the cochlea is governed by the dynamics of a Hopf bifurcation. In our cochlea model we discretise the basilar membrane into resonant sections with logarithmically decreasing characteristic frequencies. We show that the observed active behaviour of the cochlea can be modelled as a change in the quality factor of the individual resonant sections in a discretised model, and that this has dynamics which embody the Hopf bifurcation. © Austral.

The concept of safe region has been used to reduce the computation and communication cost for the continuous monitoring of k nearest neighbor (kNN) queries. A safe region is an area such that as long as a query remains in it, the set of its kNNs does not change. In this paper, we present an efficient technique to construct the safe region by using cheap RangeNN queries. We also extend our approach for dynamic datasets (the objects may appear or disappear from the dataset). Our proposed algorithm outperforms existing algorithms and scales better with the increase in k

Fibre reinforced polymer (FRP) plate reinforcement is a brittle material which has a brittle interfacial bond with concrete. This can lead to the misconception that all FRP retrofitting techniques provide brittle members and, hence, limited rotational capacity which has severe limitations for structural applications. This paper shows that the FRP reinforcement behaviour is but one of three components that govern the rotational capacity of plated reinforced concrete beam hinges. It is shown that FRP retrofitted beams and slabs can achieve ductile behaviour and provide rotational capacity and, furthermore, that the rotational capacity of FRP plated members depends very importantly on the interface bond characteristics.

Business processes are becoming increasingly collaborative and dynamic in nature. Correspondingly computer systems must provide the systems to support both the collaboration and changing work practices. This paper describes the modelling and technical requirements to support such processes. It suggests that any support system must be consistent with the more open nature of dynamic systems and provide the design methods and technical support systems to support them. The paper describes a collaborative metamodel to model dynamic systems and ways to convert the models to implementations. The paper stresses the need for lightweight technologies to support dynamic systems and uses the models to define requirements of such technologies.

The paper describes ways to model systems that dynamically change as their environment changes. The generic term complex adaptive systems (Kovacs, 2005) is increasingly used to describe systems in such environments. Complex adaptive systems are generally defined (Holland, 1995) as made up of many agents (which may represent cells, individuals, firms, projects) acting in parallel, constantly acting and reacting to what the other agents are doing. The control of complex adaptive systems tends to be highly dispersed and decentralized. The overall behaviour of the system is the result of a huge number of decisions made every moment by many individual agents. Processes in such systems need to be equally adaptive and we refer to them as complex adaptive processes. Currently there are no widely accepted methodologies to model and design complex adaptive processes. Most methodologies for information systems design focus on prescribed processes. The paper describes ways to model such systems. The models will differ from existing modeling techniques as they combine business functions with social structures in ways that facilitate social connectivity and interactivity needed to adapt to changing situations within the business context. At the same time the social networks will be used to define the knowledge requirements that capture the outcome of work exchanges to support process continuity. It develops the idea of collaboration graphs to integrate social network into business models. It develops a blueprint based on three parts, business models, collaboration and knowledge and develops models based on integrating these three components. It then demonstrates the methods in outsourcing environments and principles of implementation of the models using contemporary technologies.

Increasing collaboration in business processes has resulted in increased demand for information systems that support collaboration in business processes. Many system development methodologies, however, are oriented towards defining processes that are fixed both in their process steps and process functions. Collaborative systems, however, are more uncertain in nature and collaborative processes usually evolve to accomplish the goal. Hence requirements cannot be specified to the same level of detail. Collaborative processes are often user driven and requirements must accommodate such users by providing a flexible platform of services that can be configured by users to fit their work practices. This paper introduces the concept of collaboration level as a way to specify collaborative platforms of services and ways to implement such platforms.

Posters are used to convey information concisely and clearly. It requires judgement to decide on how much information to include, whether this information should be presented in a graphical or textual form, and how to organise the information in the space of the poster. A poster is the initial assessment task at the short course run by the International Institute of Women in Engineering (IIWE) at EPF, Ecole d'ingenieurs generaliste, and in association with ParisX1 University. This three week short course has been offered since 2001 and is intended for recently graduated or final year engineering students from diverse cultural and disciplinary backgrounds. The poster was chosen as the initial assessment task because young professionals are generally asked to present in this way at professional conferences. There were several aims associated with use of the poster: 1. to develop students' poster making skills 2. to help students who are shy or lacking confidence in English skills to be able to have a means of communication with each other and with staff 3. to initiate the discussion around the sustainability theme of the course. The poster display also defines the participants' space in a foreign university - it defines 'our space' for the duration of the course. The posters are assessed against criteria for both content and visual impact by three members of staff who provide feedback to the participants. An award for best poster is presented at the end of the course to recognise the skill involved in creating an effective poster. Participants in the 2008 IIWE course were surveyed to determine the effectiveness of presenting and using a poster considering these aims. This paper shows that the response was very positive in regards to the poster being useful for both gaining an understanding of fellow participants and their discipline and cultural diversity.

Canny edge detector is the most popular tool for edge detection and has many applications in the areas of image processing, multimedia and computer vision. The Canny algorithm optimizes the edge detection through noise filtering using an optimal function approximated by the first derivative of a Gaussian. It identifies the edge points by computing the gradients of light intensity function based on the fact that the edge points likely appear where the gradient magnitudes are large. Hexagonal structure is an image structure alternative to traditional square image structure. Because all the existing hardware for capturing image and for displaying image are produced based on square structure, an approach that uses linear interpolation described for conversion between square and hexagonal structures. Gaussian filtering together with gradient computation is performed on the hexagonal structure. The pixel edge strengths on the square structure are then estimated before the thresholds of Canny algorithm are applied to determine the final edge map. The experimental results show the edge detection on hexagonal structure using static and video images, and the comparison with the results using Canny algorithm on square structure. ©2009 IEEE.

Multi-instance learning (MIL) has many applications, including image and text categorization. One of the most effective approaches to MIL is by using Support Vector Machines with multi-instance kernels. In this paper we propose a multi-instance kernel, called MIR-Kernel, that takes into account the relational information of instances when computing similarities between bags. The relational information of instances are derived from the statistics of the distances between instances in feature space. The aim of MIR-Kernel is to efficiently capture the context in which instances occur within bags, so that it is able to better compute the similarities between bags. Experimental results on image and text categorization demonstrate the effectiveness of the proposed method compared to other methods. © 2009 IEEE.

This paper presents a system for egomotion estimation using a stereo head camera. The camera motion estimation is based on features tracked along a video sequence. The system also estimates the tridimensional geometry of the environment by fusing the visual information from multiple views. Furthermore, the paper presents comparisons between two different algorithms. The first one is by applying triangulation to 3D points. Motion estimation using 3D points suffers from the problem of nonisotropic noise due to the large uncertainty in depth estimation. To deal with this problem we present results with a second approach that works directly in the disparity space. Experimental results using a mobile platform are presented. The experiments cover long distances in urban-like environments with the presence of dynamic objects. The system presented is part of a bigger project involving autonomous navigation using vision only.

This study considers the use of artificial neural networks (ANNs) to predict the unconfined compressive strength (UCS) of soil-stabilizer mix. Radial basis function (RBF) as one of the most widely used ANN architectures is utilized to construct comprehensive models to relate the UCS of stabilized soil to the properties of natural soil and type and quantity of stabilizing additives. A comprehensive set of data obtained from previously published stabilization test results was used for model development. A subsequent parametric study was carried out and the trends of the results have been confirmed via previous laboratory studies. The RBF based estimates are compared with the experimental and numerical results of other researchers and found to be more accurate. © 2009 ASCE.

Since ARR 1987 improved statistical techniques have been presented which are ideal for producing regression relationships relating different catchment characteristics to peak flow. A unique feature of the quantile regression technique is that as different catchment characteristics become more or less important to peak flow their varying significance can be incorporated. For example the importance of losses declines for larger longer events where previous areas become saturated and start to contribute runoff. As a first step towards carrying out the quantile regression work, a database of available gauged data has been compiled. The data base is still being finalised however at the end of the proofing process, whereby gauges are checked for length of record, completeness, quality, ratings, stability of upstream development, it is expected that only a handful of gauges will be found to be suitable. Given the paucity of data it is not possible to establish relationships, by regression, between various catchment characteristics and peak flow for urban catchment. Thus the paper calls for a focus on urban gauging in Australia. This paper suggests that a goal be established, for the establishment of urban gauging sites across Australia (and the maintenance of existing sites) with the suggestion being that such work can be funded as part of climate change research.

This paper reports on the findings from focus groups, conducted at Macquarie University, on the attitudes of computing students to lectures. Students felt that two things were vital for a good lecture: (1) that the lecturer goes beyond what is written in the lecture notes; (2) that the lecture is interactive, by which students meant that the lecturer asks if students understand concepts and adjusts the delivery accordingly, and also the lecturer answers the students' questions. The students in the focus groups also discussed what makes for a bad lectures: (1) lecturers reading straight from slides; (2) lecturers who 'blame the students', by saying that students don't work hard enough and are too lazy to turn up to lectures; and (3) lecturers who cover the material too slowly or too quickly. The most prominent reason given for not attending lectures was the timetabling of lectures in such a way that students had too few classes in one day to make the sojourn to university worthwhile. Any university seeking to improve attendance at lectures should perhaps look as much to improving its timetabling practices as it does to improving the practices of its individual lecturers. © 2009, Australian Computer Society, Inc.

There are certain performance parameters like packet delay, delay variation (jitter) and loss, which are decision factors for online quality of service (QoS) traffic routing. Although considerable efforts have been placed on the Internet to assure QoS, the dominant TCP/IP - like the best-effort communications policy - does not provide sufficient guarantee without abrupt change in the protocols. Estimation and forecasting end-to-end delay and its variations are essential tasks in network routing management for detecting anomalies. A large amount of research has been done to provide foreknowledge of network anomalies by characterizing and forecasting delay with numerical forecasting methods. However, the methods are time consuming and not efficient for real-time application when dealing with large online datasets. Application is more difficult when the data is missing or not available during online forecasting. Moreover, the time cost in statistical methods for trivial forecasting accuracy is prohibitive. Consequently, many researchers suggest a transition from computing with numbers to the manipulation of perceptions in the form of fuzzy linguistic variables. The current work addresses the issue of defining a delay approximation model for packet switching in communications networks. In particular, we focus on decision-making for smart routing management, which is based on the knowledge provided by data mining (informed) agents. We propose a historical symbolic delay approximation model (HDAX) for delay forecasting. Preliminary experiments with the model show good accuracy in forecasting the delay time-series as well as a reduction in the time cost of the forecasting method. HDAX compares favourably with the competing Autoregressive Moving Average (ARMA) algorithm in terms of execution time and accuracy. © 2009, Australian Computer Society, Inc.

Its primary purpose of this study is to provide a comprehensive investigation on the controllability of a Magnetorheological (MR) gun recoil damper. Performances of MR damper under random load, mainly in the transportation applications, seismic protection in civil engineering and windrain- induced load in Cable Bridge, have been well investigated by many researchers. However, little research has been focused on the dynamic performance and its controllability of MR damper under impact load. At present, a systematic architecture has still not been formed, including its structure design, dynamicmodelling and controlling method of a MR damper subjected to impact load. In this paper, the research is developed and aims at the MR gun recoil damper. To evaluate its controllability of a MR gun recoil damper, a test rig which uses a closed bump to produce an impact load is developed. A novel large-scale singleended MR damper without the accumulator is used as the specimen. First, impact tests were done to evaluate the response time of the special designed long-stroke MR gun recoil damper, corresponding to the step signal of the operating current. Then, three revised control strategies, including on-off control method, PID control method, adaptive fuzzy control method, were investigated to confirm its controllability of the MR damper under impact load. Compared with on-off control and PID control policy, it is indicated by test results that this developed MR gun recoil damper has a bette r controllability using the adaptive fuzzy control policy. © 2009 IEEE.

The Fuzzy logic controller (FLC) has been designed on the basis of indirect vector control scheme of the IPMSM drive. The complete vector control scheme of the IPMSM drive incorporating the FLC is simulated for a IPMSM using Matlab/Simulink. The performances of the proposed FLC based IPMSM drive are investigated and compared to those obtained from the maximum torque per ampere (MTPA) based drive at various dynamic operating conditions, such as, certain change in command speed, step change in load, etc. The comparative results show that the FLC is more robust and, hence, found to be a suitable replacement of the MTPA control for the high performance industrial drive applications. ©2009 IEEE.

This paper presents an efficient and reliable algorithm for autonomous robots to build large-scale three dimensional maps by combining small local submaps. The algorithm is a generalization of our recent work on two dimensional map joining algorithm â Iterated Sparse Local Submap Joining Filter (I-SLSJF). The 3D local submap joining problem is formulated as a least squares optimization problem and solved by Extended Information Filter (EIF) together with smoothing and iterations. The resulting information matrix is exactly sparse and this makes the algorithm efficient. The smoothing and iteration steps improve the accuracy and consistency of the estimate. The consistency and efficiency of 3D I-SLSJF is demonstrated by comparing the algorithm with some existing algorithms using computer simulations.

Removal of artifacts is an important step in any research in/application of electroencephalogram (EEG). The artifacts may contain eye-blinking, muscle noise, heart signal, line noise, and environmental effect. Such noises often make the raw EEG signals not very useful for extraction/identification of physiological phenomena from EEG. The independent component analysis (ICA) is a popular technique for artifact removal in brain research and some reports demonstrate that ICA can remove the artifacts with lower (acceptable) loss of information. But, these reports select useful independent components manually, primarily by looking at the scalp-plots. This is of great inconvenience and is a barrier for BCI or real-time applications of EEG. In this paper, we demonstrate that machine learning methods could be quite effective to discriminate useful independent components from artifacts and our findings suggests the possibility of developing a 'universal" machine for artifact removal in EEG. © 2009 IEEE.

Bar chart is a very common and simple graph that is mainly used to visualize simple x, y plots of data for numerical comparisons by partitioning the categorical data values into bars and typically limited to operate on highly aggregated dataset. In todayï½s growing complexity of business data with multi dimensional attributes using bar chart itself is not sufficient to deal with the representation of such business dataset and it also not utilizes the screen space efficiently.Nevertheless, bar chart is still useful because of its shape create strong visual attention to users at first glance than other visualization techniques. In this article, we present a treemap bar chart + tablelens interaction technique that combines the treemap and bar chart visualizations with a tablelens based zooming technique that allows users to view the detail of a particular bar when the density of bars increases. In our approach, the capability of the original bar chart and treemaps for representing complex business data is enhanced and the utilization of display space is also optimized.

A new frequency and space precoding scheme for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems is presented. For frequency precoding, the data symbols to be transmitted are divided into multiple substreams, and a predefined unitary matrix is applied to each substream to obtain different linear combinations of data symbols in the substream to gain frequency diversity. For space precoding, different precoding matrices selected from a predefined orthogonal matrix are used to allocate each frequency precoded data symbol to all transmit antennas to gain spatial diversity. The number of substreams and the corresponding data symbol mapping scheme are also adaptively determined at the receiver under varying received signal strength and MIMO channel conditions, and are made available to the transmitter through a low-rate feedback channel. Simulation results show that the proposed MIMO OFDM system with adaptive substream selection can effectively exploit both frequency and spatial diversity, and deliver the maximum system throughput. © 2009 IEEE.

The mean squared error (MSE) is commonly used to measure and compare the performance of various phase estimation techniques in communications and signal processing systems. When the received signal contains recursive nuisance parameters, the MSE is extremely difficult to obtain and even the conventional modified Cramér-Rao bound (MCRB) can not be readily applied. In this paper, a recursive MSE bound and its simplified calculation method are proposed to solve the problem. As an application example, an adaptive hybrid antenna array and its associated angle-of-arrival (AoA) estimation technique are presented. The MSE of the AoA estimation is simulated and compared with the recursive MSE bound and MCRB. The results show that the proposed recursive MSE bound provides a tighter lower MSE bound than the recursive MCRB.

This paper proposes a parallel packet transmission (PPT) scheme based on orthogonal frequency division multiplexing (OFDM). The principle of the PPT scheme is to divide a packet into a number of smaller parallel packets, and transmit each smaller packet over an individual subcarrier of the OFDM symbols instead of spreading the data bits in a packet across a number of different subcarriers. It is proved theoretically that the proposed PPT scheme has higher average throughput than the conventional serial packet transmission without precoding. Furthermore, simulation results show that the OFDM system with PPT outperforms the precoded OFDM system with minimum mean squared error equalization in both uncoded and coded cases in terms of average throughput. The PPT scheme provides an alternative and simpler means to combat frequency-selective fading. © 2009 IEEE.

A new type of hybrid antenna array consisting of analogue subarrays followed by a digital beamformer is proposed for practical implementation of long range high data rate millimetre wave communications systems. An adaptive algorithm, referred to as the differential beam search (DBS), is proposed for the angle of arrival (AoA) estimation to control the phase shifters in the analogue subarrays and to perform digital beamforming. This algorithm does not need the knowledge of a reference signal and effectively solves the phase ambiguity problem in AoA estimation inherent to the practical subarray configuration. The performance of the proposed DBS algorithms is demonstrated by simulations. © 2009 IEEE.

This paper presents a magneto-thermal model for high-speed SMC motor. Due to high frequency, core loss is much greater than other losses and it is of crucial importance to be able to calculate the core loss accurately. By using time-stepping FEA, the total core loss is computed by summing up the separately calculated alternating and rotational hysteresis, eddy current and anomalous losses in each element. The core loss in each element is coupled with the thermal analysis by keeping the same mesh structure between the magnetic and thermal analyses. Other losses such as air frictional loss and rotor loss are included in the model due to high speed. This model is applied to a 2kW, 20krpm claw pole motor with a SMC core. The 3-D FEA is conducted for the core loss and temperature calculation because flux path in claw pole motor is purely three dimensional. The results are compared with experiments.

Nowadays, engine problems such as higher NOx, increase in smoke content and low brake power output due to biofuel fueled engine have been reduced by several improvements by using additives or modifications on engine itself. This paper presents a type of compositions and proper combination of selected chemical components which may be used in palm olein-diesel blends namely "Envo-Diesel". The blended component was designed as an additive package which was blended with diesel-biofuel at 99:1 up to 95:5 percent ratios. Blended fuels with additive have been used in the single cylinder engine which operated under 2000 rpm for 100 hours. Engine performance and emissions tests were conducted as well as engine deposit analysis was done after 100 hours engine operation time. The result was found that by using combined additive engine fuel consumption was decreased about 5%, NOx and SO x emission also reduced about 10% and carbon deposit was found less compared to other fuels especially for higher percentage of additive. Other results such as engine power and CO emission were found quite similar with 100% diesel fuel. These phenomena was shown that by using selected additive in certain amount found to be suitable to reduce diesel engine consumption and exhaust emissions as well as minimizing carbon deposit.

Free-convection flow through a two-dimensional rectangular box having openings at opposite corners on the vertical walls is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. Convection is induced when the box's ceiling or its floor is imposed with a temperature that is different to that of the ambient fluid, while all other walls are insulated. The fluid here is air near standard conditions, with a molecular Prandtl number of 0.707. Computation is performed for a range of Rayleigh-number values, up to about 2.7×109. Chien's turbulence model of low-Reynolds-number K-e is used. When convection is induced by a cold roof or a hot floor, higher flow rate and heat transfer occur. However the resultant flow and temperature variation are more confined to the wall regions, while the rest of the box is relatively much less affected. All this is in contrast to when convection is due to a hot roof or a cold floor.

AbstractThe feasibility of a templated seedless approach for growing segmented p-i-n nanowires –based diodes based on selective epitaxial growth is demonstrated. Such diodes are the basic structure for a TunnelFET device. This approach has the potential for being easily scalable at a full-wafer processing, and there is no theoretical limitation for control on nanowires growth and properties when scaling down their diameters, as opposed to an unconstrained vapor-liquid-solid growth. Moreover, Si/SixGe1-x hetero-structures are implemented, showing that this can improve the TFET ON current not only thanks to the lowered barrier for the band-to-band source-channel tunneling, but additionally thanks to its lower thermal budget for growth, allowing for better control of the abruptness of the doping profile at the source-channel tunneling interface.

In this study, 2D and 3D numerical analyses were conducted to predict embankment behaviour on soft clay foundations stabilised by Combined Vacuum and Surcharge Preloading. To determine the equivalent plane strain permeability, a revised conversion procedure for plane strain condition considering linear permeability variation in the smear zone is proposed. The equivalent permeability coefficients are then incorporated in finite element codes, employing the modified Cam-clay theory. The advantages and limitations of vacuum application through vertical drains are discussed through two selected case histories from China and Australia and the predictions are compared with the available field data. Apart from realistic 3D numerical modelling, it is demonstrated that the equivalent plane strain analysis can now be used as a predictive tool with acceptable accuracy. © 2009 IOS Press.

The growth of Internet offers quality and convenience to human life, but at the same time provides a platform for hackers and criminals. The Internet security hence becomes an important issue. Intrusion Detection System (IDS) is designed to detect intrusion and also to prevent a system from being compromised. In this paper, we present a novel Geometrical Structure Anomaly Detection (GSAD) model. GSAD employs pattern recognition techniques previously used in human detection [2}.

We propose a statistical model, namely Geometrical Structure Anomaly Detection (GSAD) to detect intrusion using the packet payload in the network. GSAD takes into account the correlations among the packet payload features arranged in a geometrical structure. The representation is based on statistical analysis of Mahalanobis distances among payload features, which calculate the similarity of new data against precomputed profile. It calculates weight factor to determine anomaly in the payload. In the 1999 DARPA intrusion detection evaluation data set, we conduct several tests for limited attacks on port 80 and port 25. Our approach establishes and identifies the correlation among packet payloads in a network. © 2009 IEEE.

In multiuser MIMO systems, the Channel Inversion Regularization (CIR) precoding outperforms Zero-Forcing (ZF) in the case of a small number of users and low SNR. However, unlike the zero-interference ZF, the optimal power allocation issue using CIR is a nonconvex optimization problem which will become more intractable with nonconvex QoS constraints. In this paper we focus on the challenging QoS-aware optimal power allocation problem, aiming to maximize the system sum rate and guarantee the users' minimum data rates. As a result, an "Iterative Geometric Programming" (IGP) strategy is proposed which transforms the underlying problem to a series of tractable Geometric Programming (GP) problems through an iterative convex approximation. Extensive simulations have been conducted and the results indicate that IGP is quite suitable to tackle the problem, which can achieve a good balance between the system sum rate and the individual QoS requirements. ©2009 IEEE.

In the Problem Frames (PF) approach there are five basic problem frames and some variants to them. When a problem is being analysed, it is initially matched against these frames. If the problem does not fit into the basic problem frames or their variants, then problem analysis is performed. It has been recognised that ‘projection’ is an effective technique for analysing problems. That is, each sub-problem is considered as a projection of the main problem concerned only with the phenomena relevant to that sub-problem. The PF approach lacks a precise definition of problem projection and does not provide specific instructions on how to perform this projection. In this paper, we use the concept of projection from relational algebra and combine it with concepts from the PF and scenario-based approaches to present a conceptual model for conducting problem projection in requirements engineering. This model and ontology extend problem description at scenario level and support systematic derivation of sub-problems from scenarios. We also provide a detailed process description for performing projection for problem analysis and present the utility of our approach with a case study.

We argue that conversational interactions are the most difficult to design for, but also the most interesting. To illustrate our approach to designing for conversational interactions we describe the performance work Partial Reflections 3 for two clarinets and interactive software. This software uses simulated physical models to create a virtual sound sculpture which both responds to and produces sounds and visuals.

Telemonitoring is emerging as a compelling application of Body Area Networks (BANs). We describe two health BAN systems developed respectively by a European team and an Australian team and discuss some issues encountered relating to formalization of clinical knowledge to support realtime analysis and interpretation of BAN data. Our example application is an evidence-based telemonitoring and teletreatment application for home-based rehabilitation. The application is intended to support implementation of a clinical guideline for cardiac rehabilitation following myocardial infarction. In addition to this the proposal is to establish the patientâs individual baseline risk profile and, by real-time analysis of BAN data, continually re-assess the current risk level in order to give timely personalised feedback. Static and dynamic risk factors are derived from literature. Many sources express evidence probabilistically, suggesting a requirement for reasoning with uncertainty; elsewhere evidence requires qualitatie reasoning: both familiar modes of reasoning in KBSs. However even at this knowledge acquisition stage some issues arise concerning how best to apply the clinical evidence. Furthermore, in cases where insufficient clinical evidence is currently available, telemonitoring can yield large collections of clinical data with the potential for data mining in order to furnish more statistically powerful and accurate clinical evidence.

This study investigates the rate estimation problem encountered in rehabilitation exercise monitoring by using noninvasive portable sensors. The purpose of this paper has two main parts. The first part is to find suitable approaches for the rate detection of tri-axial accelerometer (TA) signals and ECG signals respectively. It is found that the integral type approaches (the average magnitude difference function (AMDF) and autocorrelation function (ACF)) are particularly suitable for TA signal pre-processing, while differential type approaches are very efficient for electrocardiographic (ECG) signal pre-processing. The second part is to develop a square wave matching method to detect the rate from the pre-processed signals. Experimental results indicate that the proposed methods can effectively detect pace rate from TA and heart rate from ECG and remove undesirable spikes.

This paper presents experimental test results of a new compressed natural gas direct injection (CNG-DI) engine that has been developed from modification of a multi cylinder gasoline port injection (PI) engine. The major modifications done are (1) the injection system has been modified to gas direct injection using new high pressure gas injectors, (2) compression ratio has been changed from 10 to 14 through modification of piston and cylinder head, and (3) new spark plugs with long edge were used to ignite the CNG fuel. The CNG pressure at common rail was kept at 20 bar to be injected into engine cylinder. The engine has been operated with full throttle conditions to compare all the results with original base engine such as gasoline port injection engine and the CNG bi-fuel engine where the base engine has been converted to bi-fuel injection system to be operated with gasoline and CNG fuels. Hence, it can be mentioned that the original gasoline port injection engine has been modified to CNG bi-fuel and CNG-DI systems. The bi-fuel injection was developed using a gas conversion kit with gas port injection injectors. The test results obtained from CNG fuel using two different systems (i.e. bi-fuel and DI) will be investigated and compared with original gasoline engine. The test was conducted with computer controlled dynamometer to measure brake power, specific fuel consumption (SFC), exhaust emissions such as carbon monoxide (CO), oxides of nitrogen (NOx), and unburned hydrocarbon (HC). The objective of this investigation is to compare the test results between "CNG-DI", with "CNG-BI" and "gasoline - PI" engines with the same displacement volume. It was found that the CNG-DI engine produces 4% higher brake power at 6000 rpm as compared to original gasoline fueled engine. The CNG-BI engine produces maximum power of 57 kW at 5500 rpm which is 23% lower than CNG-DI engine's peak power (at 6000 rpm). The average BSFC of CNG-DI engine was 0.28% and 8% lower than gasoline-P...

On 21 December 2007 State Environmental Planning Policy (Infrastructure) 2007 (known as the 'Infrastructure SEPP') was gazetted and subsequently came into effect in NSW on 1 January 2008 to facilitate the effective delivery of infrastructure across the State. Key objectives of this planning policy were to: protect the safety and integrity of key transport infrastructure from adjacent development; and ensure that adjacent development achieves an appropriate acoustic amenity by meeting the internal noise criteria specified in the Infrastructure SEPP. A major initiative of this SEPP is that for the first time a planning instrument has established internal noise levels [35dB(A) for bedrooms and 40dB(A) for other habitable rooms] in new residential developments planned along identified transport corridors. To support the Infrastructure SEPP, the NSW Department of Planning released Development in Rail Corridors and Busy Roads - Interim Guideline in December 2008. This document was developed with significant input from acoustic experts and other government agencies, and provides guidance on building design, internal layout and architectural principles to achieve an acceptable internal acoustic environment as well as synergies in addressing air and noise impacts. The Guideline also provides general guidance on strategic planning for Councils and other government agencies, or private proponents investigating possible locations for new residential and other sensitive development that require development approval. In addition, it provides guidance on site selection to reduce or avoid the need for mitigation measures for new residential (eg single/dual occupancy, multi-unit, etc) dwellings. The present paper focuses on the aspects of the Guideline which apply to the management of road traffic noise. It presents a summary of the technical background, assumptions and considerations given in relation to all of the road traffic noise information contained within the Gu...

AbstractThis paper investigates the factors affecting medical bloggers' knowledge sharing behavior from both personal and external aspects. We develop a model based on the social cognitive theory and augment it with the social capital theory. The model is empirically examined based on the survey data collected from 75 bloggers writing on medical issues, and evaluated with confirmatory factor analysis and structural equation modeling. Among the personal factors, we examined outcome expectations including reputation and enjoyment in helping others. Encouragement by others, identification and interaction ties were investigated as external factors. Enjoyment in helping others and reputation were found to have significant direct affect on medical bloggers' knowledge sharing behavior, while encouragement by others, identification, and interaction ties showed no significant direct affect. However, encouragement by others exhibited significant impact on reputation and enjoyment in helping others. The implications for theory and practice, and future possible research are discussed.

A driver drowsiness detection analysis was performed on the electroencephalography data collected from 40 non-professional drivers undergoing a driving simulation task. A statistical comparison between two different EEG analysis methods was carried out to determine which method had a greater association with drowsiness. First, the statistical association between the alpha component of the EEG and the video-based driver drowsiness rating level was examined, and then the statistical association between the alpha bursts and the driver drowsiness level was examined. From the results it was shown that both spectral and alpha burst analysis methods showed a significant association with drowsiness, however, the alpha burst method exhibited the strongest association with the video-based drowsiness ratings.

The node position can be used to discover key network users, who are the most important in the population and who have potentially the greatest influence on others.

The evolution of user interface (UI) tools has generally regarded the UI as separable from the underlying application it represents. This viewpoint leaves the UI having to restate invariants already specified in other subsystems of an application, and any discrepancy between the versions in the UI and those in the subsystems leads to errors. This paper explores a sample of real world subsystems in use by enterprise applications today, and underscores the problem of duplication between them and the UI. It then surveys the prevalence of this issue within mainstream software development.

Abstract Associated gas is estimated to account for 17% of global gas reserves. However, majority of associated gas resources are small or located offshore which have made the utilization uneconomical. Operators have thus preferred either flaring or re-injecting the gas rather than utilization. Currently, none of these two options are favored as it is proven that gas re-injection has reverse effect on well recovery over time. Gas flaring is also not pleasant (even not permitted) because of stringent environmental regulations such as carbon tax. These reasons and the elevating energy prices have increased attentions towards utilization of associated gas resources. There are a number of gas utilization technologies that have the potential to make the development of stranded gas resources economically viable. Some of these however have not yet been fully developed and proven on a commercial scale, though being conceptually feasible. The most advanced among these alternative technologies include LNG, CNG, GTL and NGH. These processes are highly capital-intensive and require considerable gas reserves to justify their deployment. Accordingly, these technologies are challenged to be economical when the size of the field is small (like most of the associated gas resources) or the markets are located far away from the field. In this study, we have investigated each of these processes based on different variables such as reservoir capacity, distance to market, process CAPEX & OPEX, safety, etc. This paper discusses the pros and cons of these processes and presents the sweet spot for each of the technologies based on gas reserve and distance to market.

This paper presents the design and implementation of RISC processor having five stages pipelined architecture. Functional unit parallelism is exploited through the implementation of pipelining in five stages of RISC processor. The hazards which come to life due to parallelism are data, structural, and control hazards .In order to achieve the true benefits of the parallelism through pipelining; these hazards must be properly handled. The data hazards are solved using bypassing in which we forward the required value of the operand to the succeeding instruction. Structural hazards are solved by implementing three port register file so that two operand reading and one register writing can be performed in parallel without degrading the performance. Control hazards arise from Branch, Jump and Call instructions. To solve these problems, we insert automated NOP in stage2, stage3 and stage4. The processor designed is a fully functional processor which can execute any program including jump statements, switch statements, loops and subroutines which are the basic ingredients of any computer program.

A transformerless single-stage single-switch AC/DC converter was reported and analyzed recently. The converter features high power factor capability, high conversion efficiency, reduced voltage stress on bulk capacitor, low manufacturing cost and small in size. In this paper, its averaged small signal model is analyzed and presented for the control purpose. By applying small ac signal perturbations and statespace averaging technique, the crucial dynamic transfer functions are derived. Bode plots of the transfer functions are also given for designing the controller. The experimental results validate the model and show in good agreement.

Numerical simulation of ventilation flow through a real-sized 3-dimensional room containing warm air has been performed, using a commercial CFD (Computational Fluid Dynamics) software package. The standard K-e turbulence model with wall functions is used. Fans flow rate only affects significantly the rooms temperature when this rate is low, corresponding to the free-convection-dominating regime. In forced-convection regime, increasing the flow rate results in little change in the rooms temperature, but can also enlarge pockets of undesirable warm air. Positioning a window higher gives rise to more efficient ventilation. An exhaust fan reduces the rooms average temperature significantly more than an in-blowing fan.

A national Discipline-Based Initiative (DBI) project for Information and Communications Technology (ICT), funded by the Australian Learning and Teaching Council, has sought the opinions of recent graduates of ICT in the workplace to help inform the curriculum. An online survey was devised to question graduates on workplace requirements and university preparation for abilities categorized as: personal/interpersonal; cognitive; business and technical. The graduates in employment have highlighted broad mismatches between the requirements of their professional work in these categories and the preparation for employment they received from university. A regression analysis was used to determine influences on graduates' opinions of the preparation they received at university. The quantitative and qualitative results from this survey could have far-reaching consequences for ICT education and this initiative will enable the development of curricula that ensures graduates are equipped with the skills required by the ICT industry. © 2009, Australian Computer Society, Inc.

Playing games against people with a different skill level can be boring or frustrating, which decreases fun. A solution is to introduce specific rules that balance a game. In this paper we describe a study in which we used an electronic board game with tangible interaction to investigate whether balancing a game indeed increases fun experienced. We also investigate whether balancing skill levels implicitly (players are unaware) or explicitly (players are aware) has an influence on the fun experienced. We found that players who lost a game felt more successful in the balanced game compared to the unbalanced game. The balanced game also offered the players more fun experience than they expected beforehand. Finally, players preferred to play an explicitly balanced game because it increased the feeling of effort and challenge.

This paper suggests an approach to combine the analytical advantages of matrix-based notation with the modeling capabilities of graphical notation in order to model process flows including logic operators. Matrix-based notation is exemplified by Design Structure Matrices (DSM) and Multiple Domain Matrices (MDM), graphical notation by Event driven Process Chains (EPC), both being established standards in industry. DSM and MDM offer algorithmic methods for analyses, but so far without a means of modeling decision points (AND, OR, XOR). EPC allows for an easy modeling of process flows with parallel and alternative paths. However, it does not feature comprehensive analyses, making it difficult to systematically analyze a process model. In this research, MDM was therefore extended to include logic operators, thus combining the two approaches to transfer EPC and similar models into a matrix-based description and vice versa; this makes any graphical model that uses Boolean logic accessible to algorithmic analysis available in MDM. Generally spoken, the proposed modeling scheme opens up a way of generic modeling of logic operations in matrix-based notations.

Human identification by recognizing the spontaneous gait recorded in real-world setting is a tough and not yet fully resolved problem in biometrics research. Several issues have contributed to the difficulties of this task. They include various poses, different clothes, moderate to large changes of normal walking manner due to carrying diverse goods when walking, and the uncertainty of the environments where the people are walking. In order to achieve a better gait recognition, this paper proposes a new method based on Weighted Binary Pattern (WBP). WBP first constructs binary pattern from a sequence of aligned silhouettes. Then, adaptive weighting technique is applied to discriminate significances of the bits in gait signatures. Being compared with most of existing methods in the literatures, this method can better deal with gait frequency, local spatial-temporal human pose features, and global body shape statistics. The proposed method is validated on several well known benchmark databases. The extensive and encouraging experimental results show that the proposed algorithm achieves high accuracy, but with low complexity and computational time. © 2009 IEEE.

Gait is one of well recognized biometrics that has been widely used for human identification. However, the current gait recognition might have difficulties due to viewing angle being changed. This is because the viewing angle under which the gait signature database was generated may not be the same as the viewing angle when the probe data are obtained. This paper proposes a new multi-view gait recognition approach which tackles the problems mentioned above. Being different from other approaches of same category, this new method creates a so called View Transformation Model (VTM) based on spatial-domain Gait Energy Image (GEI) by adopting Singular Value Decomposition (SVD) technique. To further improve the performance of the proposed VTM, Linear Discriminant Analysis (LDA) is used to optimize the obtained GEI feature vectors. When implementing SVD there are a few practical problems such as large matrix size and over-fitting. In this paper, reduced SVD is introduced to alleviate the effects caused by these problems. Using the generated VTM, the viewing angles of gallery gait data and probe gait data can be transformed into the same direction. Thus, gait signatures can be measured without difficulties. The extensive experiments show that the proposed algorithm can significantly improve the multiple view gait recognition performance when being compared to the similar methods in literature. ©2009 IEEE.

Trading rules derived from technical analysis are valuable tools in making profits from the financial market. Among those trading rules, the moving average-based rule has been the most widely adopted choice by a large number of investors. Buy/sell signals are identified when curves of long/short averages cross each other. With an attempt to optimize the rule and maximize the trading profit, this paper propose the use of the particle swarm optimization algorithm to determine the appropriate long/short durations when calculating the averages. Trading signals are subsequently generated by the golden cross strategy. The best combination of long/short durations is determined by comparing the profits that can be made among alternative durations. Real-world indices, covering three years approximately, from several established and emerging stock markets are used to verify the effectiveness of the proposed method.

A study of color image segmentation with its dependence on color space representation is presented. Segmentation has been one of the basic procedures in image processing. Because of the three-fold increase in color signal dimension as compared to black-and-white images, an advantage resulting from the choice of color space representation could be taken to enhance the performances of processes such as segmentation and feature matching. However, the choice of a particular color space is still largely application dependent. This work attempts to study a number of popular color space schemes on the basis of the maximum information that the space is able to convey to the segmentation process. Thus, a reduction in the complexity of the segmentation procedure is achievable when it is operating on a single color space domain. The amount of information contained in the segmented objects is adopted as a measure to determine the segmentation rule. Several aerial images over planted fields are employed in experiments and their satisfactory segmentation results are used to conclude the study.

When a low voltage DC power source is used, a DC-DC converter with a high step-up voltage gain is required to raise the voltage to more applicable levels. This is typically achieved in classical converters which often have to be driven by pulse width modulation (PWM) waves with extremely high duty cycles. Although theoretically step-up converters can achieve an infinite gain as the duty cycle approaches unity, in reality the gain will peak due to losses in the converter. Increasing the duty cycle beyond this point will only degrade the voltage gain. A solution to this problem is to use a converter that will produce the desired gain at a smaller duty cycle. This paper proposes replacing the inductor in the classical boost converter with a switched-coupled-inductor (SCL) configuration in order to achieve high gains with moderate duty cycles. Mathematical analysis is presented along with selected experimental results to support the theoretical considerations.

We address the problem of control-channel jamming attacks in multi-channel ad hoc networks. Deviating from the traditional view that sees jamming attacks as a physical-layer vulnerability, we consider a sophisticated adversary who exploits knowledge of the protocol mechanics along with cryptographic quantities extracted from compromised nodes to maximize the impact of his attack on higher-layer functions. We propose new security metrics that quantify the ability of the adversary to deny access to the control channel, and the overall delay incurred in re-establishing the control channel. We also propose a randomized distributed scheme that allows nodes to establish a new control channel using frequency hopping. Our method differs from classic frequency hopping in that no two nodes share the same hopping sequence, thus mitigating the impact of node compromise. Furthermore, a compromised node is uniquely identified through its hop sequence, leading to its isolation from any future information regarding the frequency location of the control channel.

It has been suggested that future directions of HCI would need to place human values at its core. One approach towards this complex endeavor is to build an understanding of these values through examining systems designed to address them. This paper focuses on an urban installation - -CO2nfession/ CO2mmitment - -that deals with one such (societal) value: environmental sustainability. Designed to solicit personal opinions about climate change, we found the 'confessional' aspect of the installation encouraged strong reflexivity amongst 'users' with regards to this value and precipitated personal considerations about future actions. More importantly this reflexivity exposes people's lived and felt experiences about this societal value, unearthing their ambivalences, hindrances but also motivations. This installation highlights an alternate approach that can complement current efforts without taking a 'big stick' approach. Instead, urban media technologies can be harnessed to engage people with this value on their own terms, through encouraging conversations and supporting reflexivity. © ACM 2009.

The main aim and focus of this work is to examine the technologies that are currently being used by some of the professional and Olympic sports, to assist referees in making the correct decisions. Five major sports in Australia were examined through discussion groups and interviews. The participants in the study had all officiated from the grassroots level to the elite level, using the technologies being adopted by their sport. The findings present that, in the majority of the examined sports, differing degrees of technology is being applied to aid in the decision making process. When used, technology does provide a mechanism to ensure the correctness of decisions. The success of the introduction of decision support technology is dependant on its usability, appropriate application and acceptance by the officials and participants of the match. The diligent use and application of appropriate technologies can be used as an effective aid to refereeing. Since the introduction of the use of technology to assist the referee, illegal play and tactics have been dramatically reduced and to a certain extent eliminated: subsequently these technologies have been a major contributor to the provision of a fairer platform for competition and led to improved player performance. The findings provide a basis for further studies and possible trials with technologies to assist the referee in providing fair competition and to improve the quality of referees decision making.

Finite Control Set Model Predictive Control (FCS-MPC) is a novel and promising control scheme for power converters and drives. Many practical and theoretical issues have been presented in the literature, showing good performance of this technique. The present work deals with one of the most relevant aspects of any controller, namely, the steady-state operation. As will be shown, basic FCS-MPC formulations can be enhanced to achieve a zero average steady-state error. We focus on a simple H-Bridge power converter with two complementary switches and discuss benefits and drawbacks of our proposal. ©2009 IEEE.

With the technology advancement, crystal plasticity finite element modeling becomes more and more popular in the simulation of metal forming process. In order to obtain a better understanding of the difference between the Taylor model and finite element model during the simulation of metal forming process, an implicit time-integration procedure with the two polycrystal models is applied in the commercial finite element code ABAQUS to simulate the plane strain compression separately. FCC metal is used in this study. The simulation shows that the two polycrystal models both can predict the compression process approximately. The two modelling results of surface roughness show an agreement with that of the experimental results. However, the side profile calculated by the Taylor polycrystal model is much steeper and straighter than that of finite element polycrystal model. The experimental surface roughness curve shows a high frequency fluctuation. It is much steeper than those of the two models. The simulation results also show that the von Mises stress from the Taylor model is much higher than that of the finite element model.

Given an initial query and the suggested related queries, our search system concurrently processes their search result lists from an existing search engine and then forms a single list aggregated by all the retrieved lists. In particular we propose a generic rank aggregation framework which considers not only the number of wins that an item won in a competition, but also the quality of its competitor items in calculat- ing the ranking of Web items. The framework combines the traditional and random walk based rank aggregation methods to produce a more reasonable list to users. Experimental results show that the proposed approach can clearly improve the retrieval quality in a parallel man- ner over the traditional search strategy that serially returns result lists. Moreover, we also empirically investigate how different rank aggregation methods affect the retrieval performance.

Security is a critical requirement for the e-health system because the patient's sensitive information can be acessed remotely ant his makes the entire system vulnerable to malicious attacks. In this paper, we present a novel role-interaction-organization security model and apply it to the e-health system which is modeled as a multi-agent system. The roles in our proposed modeled as a multi-agent system. The roles in our proposed model do not only determine access right passively, but also initiate requests to interact dynamically with the agents who meet the security requirements. The interaction and the organization models help to identify the actions and responsibilities that a role can assume in the system within the organization and any dynamic interactions it can partake. A simple case from the e-health system is given to illustrate the application of the model.

The drawback of the small EBG-resonator antenna using a square-patch in-phase highlyreflecting surface (HRS), proposed in [1], is its narrow bandwidth. The theoretical method is cleared for analyzing the effect of the bandwidth of the in-phase HRS on the bandwidth of the EBG-resonator antenna in this paper. To enhance the gain bandwidth of the antenna according to the theoretical rule, a double-layer mushroom-type in-phase HRS surface, whose reflection phase decreases much slower with frequency than that of the square-patch HRS, is designed. Results of an antenna application with wider bandwidth at 11.9 GHz are shown. © 2009 IEEE.

This paper studies a wind-solar complementary singlephase sine wave power inverter, including the hardware structure, operating principle, and method to the charging and discharging design. A dual-level three-state intelligent float charging based on PIC single chip control is brought forward for combining the special characteristics of wind-solar energy system. It helps the automatic transfer between charging and discharging and active protection of the battery. Unattended wind-solar complementary power system is achieved. With the help of reasonable calculation and simulation analysis, the final parameters are determined. A prototype of 500W/220V/50Hz single-phase sine wave power inverter has been fabricated. Through the model experiment the output voltage waveforms are found in conformity at both no-load and full-load, and the THD is very low. Therefore, the workability and validity are proved.

An improved three-dimensional (3-D) magnetic property measurement system, which can indirectly measure the magnetic field strength H vector in a cubic sample of soft magnetic composite (SMC) material by controlling the three components of the magnetic flux density B vectors, has been developed and calibrated. This paper especially describes the improved structure of the sample with H and B sensing coils, and deals with the magnetic compensation problem. The relationship between the B vector and H vector has been measured under alternating and rotating flux conditions by using the 3-D magnetic measuring system, and the core loss features have been analyzed when the B loci are controlled as circles with increasing magnitudes and ellipses evolving from a straight line to circle in three orthogonal planes.

In content-based image retrieval (CBIR) and image screening, it is often desirable to locate the regions of interest (ROI) in the images automatically. This can be accomplished with multi-instance learning techniques by treating each image as a bag of instances (regions). Many SVM-based methods are successful in predicting the bag labels, however, few of them can locate the ROIs. Moreover, they are often based on either local search or an EM-style strategy, and may get stuck in local minima easily. In this paper, we propose two convex optimization methods which maximize the margin of concepts via key instance generation at the instance-level and bag-level, respectively. Our formulation can be solved efficiently with a cutting plane algorithm. Experiments show that the proposed methods can effectively locate ROIs, and they also achieve performances competitive with state-of-the-art algorithms on benchmark data sets.

This paper presents a new particle swarm optimization (PSO) algorithm for tuning parameters (weights) of neural networks. The new PSO algorithm is called fuzzy logic-based particle swarm optimization with cross-mutated operation (FPSOCM), where the fuzzy inference system is applied to determine the inertia weight of PSO and the control parameter of the proposed cross-mutated operation by using human knowledge. By introducing the fuzzy system, the value of the inertia weight becomes variable. The cross-mutated operation is effectively force the solution to escape the local optimum. Tuning parameters (weights) of neural networks is presented using the FPSOCM. Numerical example of neural network is given to illustrate that the performance of the FPSOCM is good for tuning the parameters (weights) of neural networks.

This paper identifies the most commonly cited conferences, journals and books of the 43 papers within the first three ICER proceedings. A large array of conferences, journals, and books were cited. However, only a small set of journals and conferences were cited frequently, and the majority were only cited within a single paper, which is consistent with a power law distribution, as predicted by Zipf's Law. The most commonly cited books are concerned with education in general (29%) or psychology (20%), while 17% of books are concerned with computer science education and 12% with computing content. The citation results for ICER are contrasted with earlier published citation analyses of SIGCSE 2007 and ACE2005-07. © 2009, Australian Computer Society, Inc.
