© 2011 by Taylor & Francis Group, LLC. Researchers have been continuously trying to improve human performance with respect to HSE and ergonomics; hereafter referred to as HSEE. This study proposes a non-parametric efficiency frontier analysis method based on the adaptive neural network (ANN) technique for measuring job satisfaction among operators with respect to HSEE. ln order to conduct this review, we have distributed questionnaires to four working shifts' operators in a gas refinery in which we used variety of questions related to HSE and Ergonomics. We have used ANN to predict the efficiency of HSE and Ergonomics and ranked the efficiencies. It should be noted that work groups have been used to satisfy the importance of teamwork in HSE and Ergonomics systems. By this approach, we assume some work teams according to some principles such as education, age and similarity in nature of works. The main objective of this article was Utilization of adaptive neural network for teamwork assessment versus HSE and Ergonomics. After defining system's efficiency against different shifts operators and ranking them, we began analyzing the results inside working groups. At first, we compared performances of individuals with teams and reviewed the average of these two by using T-test. We then reviewed the performances of different work groups (teams) by using ANOVA F -test.

Today, developing and implementing an institutional strategy for engagement is vital for developing the capacity of the university to respond to the needs of its various publics, to educate the whole student, and to realize the potential and promise of its scholars and their impact on society. Core to developing, implementing, and institutionalizing this engagement plan is the development of university leaders for the twenty-first century which necessarily means enhancing the institutional capacity to engage with community partners and to support engaged scholars. To respond to these challenges, Virginia Tech developed a week-long Engagement Academy for University Leaders to help higher education institutions develop partnerships with key external stakeholders in conducting research, teaching, and public service or outreach that will benefit the public and enhance the institution, as well as its faculty, staff, and students. Academy members were selected through a competitive nomination and selection process. The participants learned and applied concepts of engagement and engaged scholarship to develop individualized plans for institutionalizing community engagement within their institutions. This program is supported by a national advisory group, three national associations, a team of national scholars of engagement, a university president serving as a mentor-in-residence, and the recipient of the 2007 C. Peter Magrath W. K. Kellogg Foundation Engagement Award, Virginia Tech. Results of the Academy evaluation (Dubinsky, 2008) indicate that the participants gained a greater understanding of the core competencies of engagement. © 2010 by Michigan State University Press.

[Context and motivation] Ambiguity has long been pictured as one of the worst enemies of the specifier, especially with reference to ambiguity in natural language (NL) requirements specifications. [Question/problem] In this paper, we investigate the nature of ambiguity, and [Principal ideas/result] advocate that the simplistic view of ambiguity as merely a âdefect❠that has to be avoided at all costs does not do justice to the complexity of this phenomenon. We also provide a finer classification of several types of ambiguities, distinguishing their different causes and effects in the development process. [Contribution] This better understanding can help in the analysis of practical experiences and in the design of more effective methods to detect, mark and handle ambiguity.

A motion trajectory tracking method using a novel visual attention model and kernel density estimation is proposed in this paper. As a crucial step, moving objects detection is based on visual attention. The visual attention model is built by combination of the static and motion feature attention map and a Karhunen-Loeve transform (KLT) distribution map. Since the visual attention analysis is conducted on object level instead of pixel level, the proposed method can detect any kinds of motion objects provided saliency without the affection of objects appearance and surrounding circumstance. After locating the region of moving object, the kernel density is estimated for trajectory tracking. The experimental results show that the proposed method is promising for moving objects detection and trajectory tracking.

Distributed systems are growing increasingly complex in the sense that they need to reorganize on a regular basis to respond to external opportunities. At the same time research has shown that performance is improved where technology support is aligned to peopleâs activities within the system. This paper provides a framework for ensuring that such alignment is maintained during system evolution. The paper first defines the nature of change using complexity theory as the foundation for defining the nature of change. It then builds on the idea of socio-technical gaps to identify the gaps created by a change. The changes are then outlined in terms of perspectives to provide a systematic basis for managing change. To do this change is expressed in terms of the perspectives to provide a meaningful way to respond to change.

Collaboration is playing an increasing role in business especially given an increase in business networking. Such networks are formed to gain business advantage by combining expertise from many businesses or organizational units to quickly create new and competitive products and services. Most processes in business networks now consist of a number of activities whose processes must be coordinated to reach enterprises goals. This chapter addresses ways of supporting such activities using technology and proposes a collaboration infrastructure that encourages collaboration and sharing of knowledge across the activities.

Collaboration is now playing a greater role in business processes, where knowledge workers leverage knowledge to develop innovative products and services. Such business processes go beyond the goal of simply achieving a well defined outcome at minimum cost using well defined tasks. They place more emphasis on collaboration and knowledge sharing and ways to change processes as collaboration evolves. The paper calls for greater emphasis on perspectives other than process flow in process design. These are knowledge, social structure, business activity, organization and technology. The paper describes process design ways to combine these perspectives into a holistic model and converting the model a collaborative infrastructure that allows users to align collaborative technologies to their collaboration.

Process management is becoming more complex especially when business units work together to create new systems constructed from many components. The complexity arises both from the growing number of components and relationships as well as continual changes in product requirements and business arrangements. The complexity impacts on process management as support systems are needed to provide the communications and coordination to support the complex relationships and their continuing change. This paper proposes a systematic way to model such processes by developing the semantics to describe complex processes in meaningful ways. The semantics include perspectives other than those found in process flows to provide a more meaningful way to describe and model complex processes. The paper then outlines ways to convert the models to lightweight platforms that directly support the modeling concepts. The paper shows the application to complex tendering processes, which many of which now require greater flexibility and collaboration.

This chapter explores the perception and modeling of style in design relating to visuo-spatial representation and reasoning. We approach this subject via cognitive and contextual considerations significant to the role of style during designing. A designer's ability to represent and reason about design artifacts visually and spatially allows meaningful 'chunks' of design information to be utilized relative to the designer's task and context. Central to cognitive and contextual notions of style are two issues, namely the level of semantic interpretation, and the comparative method's degree of contextual sensitivity. This compound problem requires some explicit and cognitively plausible ordering principle and adaptive measure capable of allowing for dependencies in reasoning about similarities. This chapter first investigates the perception of style in relation to these modeling requirements before demonstrating and testing their implementation. We then discuss style in relation to design tasks and how they can be supported via the classification and retrieval of designs from large databases of visuo spatial information.

In real world applications, interested concepts are more likely to change rather than remain stable, which is known as concept drift. This situation causes problems on predictions for many learning algorithms including case-base reasoning (CBR). When learning under concept drift, a critical issue is to identify and determine âwhen❠and âhow❠the concept changes. In this paper, we developed a competence-based empirical distance between case chunks and then proposed a change detection method based on it. As a main contribution of our work, the change detection method provides an approach to measure the distribution change of cases of an infinite domain through finite samples and requires no prior knowledge about the case distribution, which makes it more practical in real world applications. Also, different from many other change detection methods, we not only detect the change of concepts but also quantify and describe this change.

The evolution of Internet and its successful technologies has brought a tremendous growth in business, education, research etc. over the last four decades. With the dramatic advances in multimedia technologies and the increasing popularity of real-time applications, recently Quality of Service (QoS) support in the Internet has been in great demand. Deployment of such applications over the Internet in recent years, and the trend to manage them efficiently with a desired QoS in mind, researchers have been trying for a major shift from its Best Effort (BE) model to a service oriented model. Such efforts have resulted in Integrated Services (Intserv), Differentiated Services (Diffserv), Multi Protocol Label Switching (MPLS), Policy Based Networking (PBN) and many more technologies. But the reality is that such models have been implemented only in certain areas in the Internet not everywhere and many of them also faces scalability problem while dealing with huge number of traffic flows with varied priority levels in the Internet. As a result, an architecture addressing scalability problem and satisfying end-to-end QoS still remains a big issue in the Internet. In this chapter the authors propose a policy based architecture which they believe can achieve scalability while offering end to end QoS in the Internet.

Conventional fault tree analysis in safety analysis of complex engineering systems calculates the occurrence probability of the top undesired event using probabilistic failure rates. However, it is often very difficult to obtain those failure rates well in advance due to insufficient data, environment changing or new components. Fuzzy numbers can be applied to estimate failure rates by handling linguistic terms. This study proposes a hybrid approach of Fuzzy Numbers and Fault Tree Analysis to solve the conventional problem and describes its procedures using a case study of emergency core cooling system of a typical nuclear power plant.

The potential of pyrolysis gas chromatography-mass spectrometry (Py-GCMS ) as a tool for the estimation of post-mortem age of bones has been investigated. Pig bone specimens prepared under controlled burial conditions in soil were studied and the post-mortem ages ranged from 3 to 48 months. Notable differences were observed in the data produced for younger bone specimens (<1 year) compared to specimens of greater post-mortem age (>1 year). Py-GCMS also demonstrates a relationship of particular peak ratios with the age of bones. The ratios of peaks in the pyrograms were examined and it was demonstrated that the ratios of certain pairs of peaks increase as the bone age increases.

A rigorous paradigm coordinating components is important in the design stage of large-scale software engineering. In this paper we propose a new Architecture Description Language, called ACDL, to represent the centralized-mode architectural connection in which all components are linked by a single connector. Following one usual approach to architectural description, in which component types and components are distinguished, and connectors integrate behaviors of components by specifying their coordination protocols, ACDL describes connectors in such a way that connectors are insensitive to the numbers of attached same-type components. Based on ACDL, we develop analytic techniques to facilitate the system checking of temporal properties of an architecture. In particular, our method shows to what extent one can add, delete and replace components without making the whole system lose desired temporal properties, and improves the system checking in several ways, for example enhancing the use of previous checking results to deal with new checking problems.

As the result of recent advent and rapid growth of the Internet, there have been an increasing number of corporations relying on computers and networks for communications and critical business transactions. Because of the network complexity and advanced hacking techniques, such reliance on computer networks often presents unanticipated risks and vulnerabilities. A huge volume of attacks on major sites and networks have been recently reported including those of private companies, government agencies and even military classified networks. Therefore, it is important to deploy protection measures for networks and their services from unauthorized modification, destruction, or disclosure of sensitive information. Intrusion detection systems (IDS) have emerged as an important part of todays network security infrastructure which can monitor the network traffic and detect possible attacks. Currently existing IDS suffer from low detection accuracy and system robustness for new and rare security breaches.

Where would we be without our personal memories? We use them to maintain our personal identities, to start and media relationships, to shape our likes, dislikes, to regulate our moods and to solve problems. They allow us to share rich life experiences and tell our stories to family and friends. There is no question about the importance of the memories of the events that happen in our lives. As more and more media become digital (whether these be photos, videos/audio snippets, olfactory or haptic cues), new ways of cueing our memory our emerging. My design research focuses on ordinary people using digital media to help them remember everyday situations. For example, by using digital photos to facilitate communication between parents and teens, organizing digital photo collections through smart interactive photo collages, but also by supporting mourners remembering a loved one.

Movie affective content analysis attracts increasing research efforts since affective content not only affect users attentions but also locate movie highlights. However, affective content retrieval is still a challenging task due to the limitation of affective features in movies. Scripts provide direct access to the movie content and represent affective aspects of the movie. In this paper, we utilize scripts as an important clue to retrieve video affective content. The proposed approach includes two main steps. Firstly, affective script partitions are extracted by detecting emotional words. Secondly, affective partitions are validated by using visual and auditory features. The results are encouraging and compared with the manually labelled ground truth.

This article describes work undertaken to evaluate an approach for developing collaborative requirementsanalysis CASE tools that are specifically designed to address the needs of cross-time-zone development teams, that is, teams spread across different geographical locations around the world. Few of the software requirements analysis computer assisted software environment (CASE) tools readily available are designed specifically for cross-time-zone development activities. We propose a specifically tailored data and knowledge-transfer model, and investigate its suitability for the development of a cross-time-zone oriented CASE tool. The approach was used to develop a working prototype. The approach and prototype will be further evaluated in a collaborative undertaking involving the Wroclaw University of Technology, the University of Technology Sydney and the University of Arizona (UA).

The removal of metsulfuron methyl (MSM) from aqueous solution (a sulfonyl urea herbicide) was investigated by adsorption both in batch and fixed bed processes. Coal based granular activated carbon (GAC) was used as an adsorbent. The adsorption equilibrium, isotherms and kinetics of MSM were studied and the data was fitted into various mathematical models. The adsorption equilibrium was fitted by Langmuir and Freundlich isotherms. Homogeneous surface diffusion model (HSDM) kinetic equation with Langmuir and Freundlich adsorption isotherm model was successfully applied to predict the adsorption kinetics data for various concentrations of MSM. The average mass transfer coefficients (kf) were 2.125 105 and 2.198 105 m/s with the Langmuir and Freundlich adsorption isotherm model, respectively. The Bohart-Adams, Thomas, and Yoon and Nelson empirical models were attempted to fit long term column adsorption data. Overall, the Thomas model was found to best simulate the fixed bed adsorption of MSM.

Mapping and Recognition of Radio Frequency Clutter in Various Environments in AustraliaRadio frequency spectrum mapping allows determining the radio frequency signatures prevalent within an environment. We address the primary frequency bands used for cellular, wireless Local Area Network (LAN), Universal Mobile Telecommunications System (UMTS) and Ultra-wideband (UWB) communications. The purpose of the experiment presented in this paper is to map the detected radio frequencies within an environment and display the collated data on a graphical user interface. A program identifies the presence of the aforementioned radio frequency signatures and recognizes signal levels which exceed the exposure standards enforced by the Australian Communication and Media Authority. The results assist in the understanding of the ramifications of long-term exposure to radio frequency radiation associated with the continued proliferation of wireless devices.

In Mobile Ad hoc Network (MANET), mobility, traffic and node density are main network conditions that significantly affect performance of routing protocols. Much of the previous research in MANET routing have focused on developing strategies, which suit one specific networking scenario. Therefore, there is no existing protocol that can work well in all different networking scenarios. This paper reviews characteristics of several different classes of routing protocols. Moreover, most of current routing protocols assume homogeneous networking conditions where all nodes have the same capabilities and resources. This paper presents extensive studies simulations for DSR, AODV, LAR1, FSR and WRP in homogenous and heterogeneous networks that consist of different nodes with different resources. The results showed that while all protocols perform reasonably well in homogenous networking conditions, their performance suffer significantly over heterogonous networks.

AbstractCeramic‐on‐ceramic (CoC) bearings in total hip replacements (THRs) have shown low wear volumes under standard gait in hip simulator studies. However, clinical reports have indicated variations in wear rates and formation of stripe‐like wear area on the ceramic femoral heads. The aim of this study was to investigate the influence of cup inclination angle and microseparation on the wear of CoC bearings in THRs. The six station Leeds II Physiological Anatomical Joint Simulator was used to investigate the wear of 28 mm diameter alumina matrix composite ceramic bearings (BIOLOX® delta). It was shown that increasing the cup inclination angle from 55o to 65o had no significant effect on the wear rate of BIOLOX® delta CoC under both standard gait and microseparation conditions in this in vitro study. Under standard gait conditions, the mean wear rate for both cup inclination angle conditions was very low at 0.05 mm3/million cycles. The introduction of microseparation to the standard gait cycle increased the mean wear rates to 0.13 mm3/million cycles for the cup inclination angle of 55o and 0.11 mm3/million cycles for that of 65°. The level of increased wear with microseparation was not dependent on cup angle. A stripe of wear on the head also formed, with corresponding superior rim wear on the cup. The wear rates obtained were low compared to the HIPed third generation alumina ceramic (BIOLOX® forte) tested under the same adverse conditions (1.84 mm3/million cycles). BIOLOX® delta has shown lower wear than previous ceramic materials used in THR under ...

Ultra-WideBand (UWB) communications has emerged as a promising technology for high data rate Wireless Personal Area Networks (WPANs). In this article, we address two key issues that impact the performance of a multihop UWB-based WPAN: throughput and transmission range. Arbitrary selection of routes in such a network may result in reserving an unnecessarily long channel time, and hence low network throughput and high blocking rate for prospective reservations. To remedy this situation, we propose a novel cross-layer resource allocation design. At the core of this design is a routing technique (called RTERU) that uses the allocated channel time as a routing metric. RTERU exploits the dependence of this metric on the multiple-rate capability of an UWB system. We show that selecting the route that consumes the minimum channel time while satisfying a target packet delivery probability over the selected route is an NP-hard problem. Accordingly, RTERU resorts to approximate path selection algorithms (implemented proactively and reactively) to find near-optimal solutions at reasonable computational/communication overhead. We further enhance the performance of RTERU by integrating into its design a packet overhearing capability. Simulations are used to demonstrate the performance of our proposed solutions.

In this paper a first time attempt has been made to measure the low strain shear modulus of clean and fouled ballast using a seismic survey of Multi-channel Analysis of Surface Wave (MASW). A model rail track was built with nine sub-sections, each having different fouling characteristics. MASW survey was performed in the top of each section of ballast and shear wave velocity was measured. The shear modulus of ballast fouled by pulverized rock, clayey sand and coal was calculated by using shear wave velocities and densities of each section and presented. The optimum and critical fouling points are defined considering the shear stiffness and drainage criteria for ballast fouled by clayey sand and coal. In both cases the shear stiffness increased to a maximum and then decreased as the percentage of fouling increased. The degree of fouling corresponding to the maximum shear wave velocity is defined as the optimum fouling point. After a particular degree of fouling the shear stiffness decreased less than clean ballast and the corresponding drainage condition become unacceptable. This point is defined as the critical fouling point. The results obtained from the model track were compared with the field data. © 2010 Taylor & Francis.

Combining Popular Game Consoles and OSGi to Investigate Autonomous In-The-Field Biomedical Data Acquisition and ManagementThe need and interest in conducting biomedical research outside the traditional laboratory is increasing. In the field testing such as in the participant's home or work environment is a growing consideration when undertaking biomedical investigation. This type of research requires at a minimum semi-autonomous computer systems that collect such data and send it back to the laboratory for processing and dissemination with the smallest amount of attendance by the participant or even the experimenter. A key aspect of supporting this type of research is the selection of the appropriate software and hardware components. These supporting systems need to be reliable, allow considerable customizability and be readily accessible but also able to be locked down. In this paper we report a set of requirements for the hardware and software for such a system. We then utilise these requirements to evaluate the use of game consoles as a hardware platform in comparison to other hardware choices. We finish by outline one particular aspect of the supporting software used to support the chosen hardware platform based on the OSGi framework.

Stormwater runoff from urban and suburban areas generates numerous pollutants. The areas include residential areas, parks, commercial areas, industrial areas and road/highways. Land use and human activities largely determine the nature and level of pollutants. Among the various types of pollutants that can contribute to adverse water quality impact in receiving water bodies, of concern are suspended solids, heavy metals, polycyclic aromatic hydrocarbons and nutrients. This paper provides a critical review of the characteristics and sources of urban stormwater pollutants and the manner in which the pollution occurs. Treatment systems for urban stormwater runoff and for urban stormwater harvesting are discussed.

In microfiltration, a deposit of foulant tends to form on the membrane surface and this usually controls the performance of the filtration process. This paper discusses the influence of physical parameters such as aeration and permeates flux on migration and deposition of above micron particles on the membrane surface. Kaolin clay suspension of particle 3.7–8 μm with mean particle diameter 4.1 μm was used in this study. Equal amount of mass of deposited particles on the membrane surface created different transmembrane pressure (TMP) when operated at different aeration rates and permeate flux showing that there is a composite effect. The particle deposition rate at the beginning at lower flux was almost linear which changed to a sharp logarithamic rise at higher flux. The difference in TMP rise for the same amount of deposit demonstrated the selective nature of particle deposition. The mass of the particle deposition on the membrane surface could be described by two parameters: maximum deposition and time using a simple empirical logarithamic equation y=k/[1+exp(b−at)], where k, a, and b are constant; y is the particulate mass deposit (g/m2) and t is the time. The maximum particle mass deposition growth could be described by the equation dy/dt=1/4ka.

This study forms a part of the physical study of the membrane bioreactor in presence of buoyancy media. Kaolin clay suspension with buoyancy media (anthracite) was used as a suspension and the particle layer development on membrane surface with evolution of time was studied. Presence of buoyancy media reduced the pressure development by almost two folds compared to in absence of the media. The particles deposition on membrane surface was size selective. The mean particle diameter (0.45 μm) deposited on the membrane surface remained almost similar in presence of the media after 7 hrs run where as in its absence the mean diameter finer particles deposition occurred at the beginning followed by coarser particles.

An investigation was made into the emissions of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) as well as inorganic gases (e.g. CO) from a wood fired combustion boiler using wood pellets, under two different boiler operating modes. Levels of total PAHs varied from 6.4 and 154 µg m-3, and were found to be dominating in the gas phase (>80%), regardless of pellet type and boiler operating mode. In addition to this, PAH concentrations were higher in slumber mode than in full flame, and increased with the moisture content of pellets, consistent with the lower combustion efficiency in slumber mode (58.664.3%) than in full flame (74.482.3%). PAHs in the gas phase comprised mainly of low molecular mass compounds, while PAHs in the particulate phase were mostly composed of high molecular mass compounds, consistent with the physicochemical properties of such compounds. In comparison to PAHs, significantly lower concentrations of PCBs (a maximum of 2.5 µg m-3) were released from pellet combustion, consistent with the virgin nature of the pellets. The PCBs in both the gas and particulate phases were dominated by hexachlorinated congeners, although congeners with more chlorine substitution were more abundant in the particulate phase than in gas phase. Significant relationships were established between CO and organic pollutants, and between PAHs and PCBs, which are useful tools for prediction purposes.

In today's working environment, there is a great desire to identify the critical attributes for sensitivity analysis of inefficient decision-making units (DMUs) regarding personnel attributes. An integrated algorithm, which uses data envelopment analysis (DEA) and data mining tools including fuzzy C-means (FCM), rough set theory (RST), artificial neural network (ANN), cross validation test technique (CVTT) and analysis of variance (ANOVA), is proposed to asses the impact of personnel attributes on efficiency. DEA is used for DMUs' efficiency evaluation. ANN is employed with regard to its ability to model linear and non-linear systems. As numerous inputs are not useful for ANN modelling, RST and ANN are combined to resolve this issue. RST is used to decrease the time of decision-making. FCM is used for data clustering and finally ANOVA is utilised for identification of attributes importance. The proposed algorithm is applied to an actual banking system.

This study presents an integrated fuzzy regression and time-series technique to estimate and predict electricity demand. Furthermore, it is difficult to model uncertain behaviour of energy consumption with only conventional time-series and fuzzy regression, which could be an ideal substitute for such cases. After reviewing various fuzzy regression models and studying their advantages and shortcomings, the best model is selected. Also, the impact of data preprocessing and post-processing on the fuzzy regression performance is to study and to show that this method does not contribute to the efficiency of the model. In addition, another unique feature of this study is utilisation of autocorrelation function to define input variables versus trial and error method. At last, the comparison of actual data with fuzzy regression and ARIMA model, using Granger-Newbold test, is achieved. Monthly electricity consumption of Iran from 1995 to 2005 is considered as the case of this study. Copyright © 2010 Inderscience Enterprises Ltd.

This paper presents a fuzzy regression approach for estimation of electricity demand in residential sector with imprecise data. Moreover, electricity consumption in residential sector plays an important role in economical decision-making process. This is also highlighted by the fact that residential sector has the largest share of consumption among all the other sectors including industrial, business, and so on. The importance of fuzzy regression becomes evident by facing imprecise quantities and insufficient amount of data for estimation of energy consumption in residential sector. Fuzzy regression is applied to Iranian residential sectors. A review of a fuzzy linear regression is presented in which the centre regression line has the best ability to interpret training data. The interpretation ability of the regression line can be measured by the proposed index of confidence. Finally, an estimation of electricity demand function in residential sector for three different values of h is presented. Copyright © 2010 Inderscience Enterprises Ltd.

Effluent discharges at Rodbourne sewage treatment works (STWs) were assessed using chemical and in vitro biological analysis as well as modelling predictions. Results showed that Rodbourne STW discharged less estrone (E1) than expected, but similar 17ß-estradiol (E2) and 17a-ethinyl estradiol (EE2) to those predicted by a widely cited effluent prediction model. The Exposure Analysis Modelling System (EXAMS) model was set up using measured effluent concentrations as its starting point to predict estrogen concentrations along a 10 km length of the receiving water of the River Ray. The model adequately simulated estrogen concentrations along the river when compared to July 2007 measured data. The model predicted combined estrogen equivalents in reasonable agreement with estrogenicity as measured by passive sampler (POCIS) extracts using the yeast estrogen screen. Using gauged mean flow values for 2007 the model indicated that the most important determinand for estrogen exposure in the Ray was not season, but proximity to the Rodbourne effluent. Thus, fish in the first 3 km downstream of Rodbourne were typically exposed to two or even three times more estrogens than those living 710 km further downstream. The modelling indicated that, assuming the effluent estrogen concentrations measured in February 2008 were typical, throughout the year the whole length of the Ray downstream of Rodbourne would be estrogenic, i.e. exceeding the 1 ng/L E2 equivalent threshold for endocrine disruption.

Body area wireless sensor networks (BAWSNs) are time-critical systems that rely on the collective data of a group of sensor nodes. Reliable data received at the sink is based on the collective data provided by all the source sensor nodes and not on individual data. Unlike conventional reliability, the definition of retransmission is inapplicable in a BAWSN and would only lead to an elapsed data arrival that is not acceptable for time-critical application. Time-driven applications require high data reliability to maintain detection and responses. Hence, the transmission reliability for the BAWSN should be based on the critical time. In this paper, we develop a theoretical model to measure a BAWSN's transmission reliability, based on the critical time. The proposed model is evaluated through simulation and then compared with the experimental results conducted in our existing Active Care Loop Framework (ACLF). We further show the effect of the sink buffer in transmission reliability after a detailed study of various other co-existing parameters.

Urban stormwater runoff is a transport medium for many contaminants from anthropogenic sources. There are many alternative management strategies available to treat these contaminants. One of the technologies suggested for this purpose is the use of permeable pavements to minimise the quantity of surface runoff generated by impervious surfaces within an urban catchment. Reported herein are the results of a monitoring program undertaken to assess the effectiveness of permeable road surface for managing the quantity and quality of stormwater runoff. It was found that the catchment, where the permeable road surface was installed, had the effective imperviousness reduced from 45% prior to reconstruction of the road surface to less than 5% after reconstruction of the road. Furthermore, it was found that the generation of surface runoff from the permeable road surface required a rainfall intensity in excess of 20 mm/h. Finally, the quality of the surface runoff was found to be at the lower levels of runoff from road surfaces. © 2010 Taylor & Francis.

The emergence of various technologies has since pushed researchers to develop new protocols that support high density data transmissions in Wide Area Networks. Many of these protocols are TCP protocol variants, which have demonstrated better performance in simulation and several limited network experiments but have limited practical applications because of implementation and installation difficulties. On the other hand, users who need to transfer bulk data (e.g., in grid/cloud computing) usually turn to application level solutions where these variants do not fair well. Among protocols considered in the application level solutions are UDP-based protocols, such as UDT (UDP-based Data Transport Protocol) for cloud /grid computing. Despite the promising development of protocols like UDT, what remains to be a major challenge that current and future network designers face is to achieve survivability and security of data and networks. Our previous research surveyed various security methodologies which led to the development of a framework for UDT. In this paper we present lowerlevel security by introducing an Identity Packet (IP) and Authentication Option (AO) for UDT.

Forest fires cause significant economic damages and hazard to environment all over the world. Apart from preventive measures, early warning and fast extinction of fires are the only chance to avoid major casualties and damage to nature. This paper describes methodology based on remote sensing and GIS for provision of various early warning of forest fire (so called hot spots) danger conditions for regulatory authorities to take actions for mitigation. Hot spot locations were identified through an automated procedure from high temporal satellite images such as MODIS and NOAA AVHRR scenes. Combination of the Daily Hotspot Images coupled with various GIS layers was used to generate Active Forest Fire Map for the study area. Results from the model can support detection and monitoring for wild fires in the forest and enhance alert system junction by simulating and visualizing forest fire and helps for contingency planning.

Preparation of L and slide susceptibility maps is important for engineering geologists and geomorphologists. However, due to complex nature of L and slides, producing a reliable susceptibility map is not easy. In recent years, various data mining and soft computing techniques are getting popular for the prediction and classification of L and slide susceptibility and hazard mapping. This paper presents a comparative analysis of the prediction capabilities between the neural network and fuzzy logic model for L and slide susceptibility mapping in a geographic information system (GIS) environment. In the first stage, L and slide-related factors such as altitude, slope angle, slope aspect, distance to drainage, distance to road, lithology and normalized difference vegetation index (ndvi) were extracted from topographic and geology and soil maps. Secondly, L and slide locations were identified from the interpretation of aerial photographs, high resolution satellite imageries and extensive field surveys. Then L and slide-susceptibility maps were produced by the application of neural network and fuzzy logic approahc using the aforementioned L and slide related factors. Finally, the results of the analyses were verified using the L and slide location data and compared with the neural network and fuzzy logic models. The validation results showed that the neural network model (accuracy is 88%) is better in prediction than fuzzy logic (accuracy is 84%) models. Results show that 'gamma' operator (X = 0.9) showed the best accuracy (84%) while 'or' operator showed the worst accuracy (66%).

AbstractBone size is a determinant of bone strength and tracks in its percentile of origin during childhood and adolescence. We hypothesized that the ranking of an individual's femur length (FL) is established in early gestation and tracks thereafter. Fetal FL was measured serially using 2D ultrasound in 625 Norwegian fetuses. Tracking was assessed using Pearson correlation, a generalized estimating equation model, and by calculating the proportion of fetuses whose FL remained within the same quartile. Baseline FL Z‐score (weeks 10 to 19) and later measurements correlated, but more weakly as gestation advanced: r = 0.59 (weeks 20 to 26); r = 0.45 (weeks 27 to 33); and r = 0.32 (weeks 34 to 39) (p < 0.001). Tracking within the same quartile throughout gestation occurred in 13% of fetuses. Of the 87% deviating, 21% returned to the quartile of origin, so 34% began and ended in the same quartile, 38% deviated by one quartile, and 28% deviated by two or more quartiles by the end of gestation. A standard deviation higher baseline FL Z‐score, placental weight (150 g), maternal height (5 cm), and weight (10 kg), was associated with a 0.25, 0.15, 0.10, and 0.05 SD higher FL Z‐score at the end of gestation, respectively (p ranging from <0.001 to 0.02). Tracking within the same percentile throughout the whole of gestation, as suggest by growth charts, is uncommon. Deviation from tracking is more common and is the result of changes in growth velocity within and between fetuses and is partly influenced by maternal, fetal, and placental factors. © 2010 American Society for Bone and Mineral Research

SUMMARY A spider orb web is an extended phenotype; it modifies and interacts with the environment, influencing spider physiology. Orb webs are plastic, responding to variations in prey parameters. Studies attempting to understand how nutrients influence spider orb-web plasticity have been hampered by the inability to decouple prey nutrients from other, highly correlated, prey factors and the intrinsic link between prey protein and prey energy concentration. I analyzed the nutrient concentrations of cockroaches, and adult and juvenile crickets to devise experiments that controlled prey protein concentration while varying prey size, ingested mass, energy concentration and feeding frequency of the orb web spider Argiope keyserlingi. I found that A. keyserlingi alters overall architecture according to feeding frequency. Decoration length was inversely related to ingested prey mass and/or energy density in one experiment but directly related to ingested prey mass in another. These contradictory results suggest that factors not examined in this study have a confounding influence on decoration plasticity. As decorations attract prey as well as predators decreasing decoration investment may, in some instances, be attributable to benefits no longer outweighing the risks. Web area was altered according to feeding frequency, and mesh size altered according to feeding frequency and prey length. The number of radii in orb webs was unaffected by prey parameters. A finite amount of silk can be invested in the orb web, so spiders trade-off smaller mesh size with larger web capture area, explaining why feeding frequency influenced both web area and mesh size. Mesh size is additionally responsive to prey size via sensory cues, with spiders constructing webs suitable for catching the most common or most profitable prey.

SUMMARY The chemical and mechanical properties of spider major ampullate (MA) silks vary in response to different prey, mostly via differential expression of two genes – MaSp1 and MaSp2 – although the spinning process exerts additional influence over the mechanical properties of silk. The prey cues that initiate differential gene expression are unknown. Prey nutrients, vibratory stimuli and handling have been suggested to be influential. We performed experiments to decouple the vibratory stimuli and handling associated with high and low kinetic energy prey (crickets vs flies) from their prey nutrients to test the relative influence of each as inducers of silk protein expression in the orb web spider Nephila pilipes. We found that the MA silks from spiders feeding on live crickets had greater percentages of glutamine, serine, alanine and glycine than those from spiders feeding on live flies. Proline composition of the silks was unaffected by feeding treatment. Increases in alanine and glycine in the MA silks of the live-cricket-feeding spiders indicate a probable increase in MaSp1 gene expression. The amino acid compositions of N. pilipes feeding on crickets with fly stimuli and N. pilipes feeding on flies with cricket stimuli did not differ from each other or from pre-treatment responses, so these feeding treatments did not induce differential MaSp expression. Our results indicate that cricket vibratory stimuli and handling interact with nutrients to induce N. pilipes to adjust their gene expression to produce webs with mechanical properties appropriate for the retention of this prey. This shows that spiders can genetically alter their silk chemical compositions and, presumably, mechanical properties upon exposure to different prey types. The lack of any change in proline composition with feeding treatment in N. pilipes suggests that the MaSp model determined for Nephila clavipes is not universally applicable to all...

This article reports on a study to identify electroencephalography (EEG) signals with potential to provide new BCI channels through mental motor imagery (MMI). Leg motion was assessed to see if left and right leg MMI could be discriminated in the EEG. The study also explored simultaneous observation of leg movement as a means to enhance MMI evoked EEG signals. The results demonstrate that MMI of the left and right leg produce a contralateral preponderance of EEG alpha band desynchronization, which can be spatially discriminated. This suggests that lower extremity MMI could provide signals for additional BCI channels. The study also shows that movement imitation enhances alpha band desynchronization during MMI, and might provide a useful aid in the identification and training of BCI signals. © International Federation for Medical and Biological Engineering 2010.

Purpose – Over the past decade telecommunications media and technology (TMT) has driven a new era that has evolved into the digital age. There is a growing consensus in developed countries that TMT is the most important driver of economic and social development for a society. Its genesis began in the USA and its cultural preference for market-based development set the framework for national policy and development. Recently the formation of convergence regulators amongst many of the leading nations has begun another episode. This article aims to explore and build upon a research study of the senior executives of six of the leading convergence regulators in Asia and Europe. The article aims to analyse by way of a numeric comparison expert views of the key convergence issues three and five years out. Design/methodology/approach – A generic conceptual model was constructed of the foundation, social and economic dividend issues. By examining the relative progress of nations developments of these issues and their different approaches, new insights are developed into different regulatory approaches. Findings – The concept of proactive regulation with competition (PRC) would appear to have benefits for a number of these nations. It is hoped that these research outcomes and hypotheses will generate further research and analysis amongst the world's leading regulators in order to work through the best regulatory approaches for the current challenges. Originality/value – The paper presents original research regarding regulatory challenges. © 2010, Emerald Group Publishing Limited

This article, written by Assistant Technology Editor Karen Bybee, contains highlights of paper IPTC 14083, ’Evaluation of LNG, CNG, GTL and NGH for Monetization of Stranded Associated Gas With the Incentive of Carbon Credit,’ by R. Khalilpour, SPE, and I.A. Karimi, Department of Chemical and Biomolecular Engineering, National University of Singapore, originally prepared for the 2009 International Petroleum Technology Conference, Doha, Qatar, 7-9 December. Associated gas is estimated to account for 17% of global gas reserves. However, the majority of associated-gas resources are small or located offshore, which has made their use uneconomical. Operators thus have preferred either flaring or reinjecting the gas rather than use. There are a number of gas technologies that have the potential to make the development of stranded gas resources economically viable. The full-length paper details a study that investigated each of these processes on the basis of different variables.   Introduction Associated gas is natural gas found in association with crude oil. According to the latest data from the Energy Information Administration, the total world gas reserves are approximately 6,200 Tcf. Some studies have estimated that global associated-gas reserves without commercial value exceed 1,000 Tcf. The National Geographic Data Center through collaboration with the World Bank’s Global Gas Flaring Reduction (GGFR) partnership is carrying out a project to develop a method to estimate global gas-flaring volumes on the basis of satellite-sensor observations. The center has reported the global volume at approximately 4.9 to 6.1 Tcf/yr within the period of 1994–2008, with a maximum amount of 6.1 Tcf in year 2005 and minimum of 4.9 Tcf in 2008. This amount of gas accounts for approximately 5 to 6% of total world natural-gas consumption. ...

Worldwide the introduction of dispersed generators (DG) in the distribution network is assuming a significant importance. There is an increasing relevance of the energy process efficiency improvement; as for electric power systems, the most interesting perspective concerns the capability of the system to increase the exploitation of the renewable resources. The integration of DGs in the electric distribution network requires a revision of this infrastructure, so far designed and developed assuming that power flows in one direction: from the high voltage transmission network to the medium voltage distribution, to reach final customers on the low voltage network. The attention to an efficient operation of distribution networks is increasing all over the world; this interest is becoming higher and higher also in Italy, where the high energy prices push in the direction of fostering efficiency as much as possible. This work describes a study developed in the Alpenergy project framework: an International Cooperation Program aimed at introducing an efficient operational model for the distributed production and consumption. In particular it is proposed a new model for the integration and the management of the DG in the distribution network. The new model (defined VPS: Virtual Power System) is based on a communication channel between the active users (generators), the loads and, eventually, the Distribution System Operators (DSOs).

A new frequency-reconfigurable quasi-Yagi dipole antenna is presented. It consists of a driven dipole element with two varactors in two arms, a director with an additional varactor, a truncated ground plane reflector, a microstrip-to-coplanar-stripline (CPS) transition, and a novel biasing circuit. The effective electrical length of the director element and that of the driven arms are adjusted together by changing the biasing voltages. A 35% continuously frequency-tuning bandwidth, from 1.80 to 2.45 GHz, is achieved. This covers a number of wireless communication systems, including 3G UMTS, US WCS, and WLAN. The length-adjustable director allows the endfire pattern with relatively high gain to be maintained over the entire tuning bandwidth. Measured results show that the gain varies from 5.6 to 7.6 dBi and the front-to-back ratio is better than 10 dB. The H-plane cross polarization is below -15 dB, and that in the E-plane is below -20 dB. © 2006 IEEE.

Traditional data mining research mainly focus]es on developing, demonstrating, and pushing the use of specific algorithms and models. The process of data mining stops at pattern identification. Consequently, a widely seen fact is that 1) many algorithms have been designed of which very few are repeatable and executable in the real world, 2) often many patterns are mined but a major proportion of them are either commonsense or of no particular interest to business, and 3) end users generally cannot easily understand and take them over for business use. In summary, we see that the findings are not actionable, and lack soft power in solving real-world complex problems. Thorough efforts are essential for promoting the actionability of knowledge discovery in real-world smart decision making. To this end, domain-driven data mining (D3M) has been proposed to tackle the above issues, and promote the paradigm shift from ÃÂdata-centered knowledge discoveryÃÂ to ÃÂdomain-driven, actionable knowledge delivery.ÃÂ In D3M, ubiquitous intelligence is incorporated into the mining process and models, and a corresponding problem-solving system is formed as the space for knowledge discovery and delivery. Based on our related work, this paper presents an overview of driving forces, theoretical frameworks, architectures, techniques, case studies, and open issues of D3M. We understand D3M discloses many critical issues with no thorough and mature solutions available for now, which indicates the challenges and prospects for this new topic.

The in-depth analysis of human behavior has been increasingly recognized as a crucial means for disclosing interior driving forces, causes and impact on businesses in handling many challenging issues such as behavior modeling and analysis in virtual organizations, web community analysis, counter-terrorism and stopping crime. The modeling and analysis of behaviors in virtual organizations is an open area. Traditional behavior modeling mainly relies on qualitative methods from behavioral science and social science perspectives. On the other hand, so-called behavior analysis is actually based on human demographic and business usage data, such as churn prediction in the telecommunication industry, in which behavior-oriented elements are hidden in routinely collected transactional data. As a result, it is ineffective or even impossible to deeply scrutinize native behavior intention, lifecycle and impact on complex problems and business issues. In this paper, we propose the approach of behavior informatics (BI), in order to support explicit and quantitative behavior involvement through a conversion from source data to behavioral data, and further conduct genuine analysis of behavior patterns and impacts. BI consists of key components including behavior representation, behavioral data construction, behavior impact analysis, behavior pattern analysis, behavior simulation, and behavior presentation and behavior use. We discuss the concepts of behavior and an abstract behavioral model, as well as the research tasks, process and theoretical underpinnings of BI. Two real-world case studies are demonstrated to illustrate the use of BI in dealing with complex enterprise problems, namely analyzing exceptional market microstructure behavior for market surveillance and mining for high impact behavior patterns in social security data for governmental debt prevention. Substantial experiments have shown that BI has the potential to greatly complement the existing empirical...

We discuss networked sensing technology for detection and monitoring of electromagnetic fields. We elaborate on software engineering issues for the visualization in real time of electromagnetic field mappings and the dissemination of information through various means and levels of access. We propose the database be complimented by a data algorithmic software solution for the extraction of patterns.

Energy is one of the most critical ingredients for economic development and prosperity of any nation. It is more so for a developing country like Thailand where energy is critically needed in order to realize the economic growth aspirations of the country. The task of providing adequate and reliable energy has however emerged as a challenging policy issue for Thailand, particularly when viewed in the context of the evolving socio-economic dynamics of the country, typified by an energy sector that is in the throes of reform, resource scarcity, energy dependence, industrial development and high economic growth. In order, therefore, to satisfy the expected energy requirements and sustain economic prosperity, effective national energy policies would be needed. A review of the existing energy policies suggests that these policies are somewhat narrow, fragmented and insular. They therefore are unlikely to be able to satisfactorily meet the energy needs of Thailand. This deficiency could however - this paper contends - be overcome by taking a fresher perspective on the nature of policy challenges and strategies to redress them. Such a perspective, this paper further argues, could be assisted by adopting a comprehensive framework that could accommodate the specificities of Thailand while integrating the technical, economic, environmental and political dimensions of the energy sector in a cohesive and consistent manner. This paper is an early attempt at developing such a framework.

Water mining is the process of extracting valuable water from a sewerage network by treating raw sewage to high standards. A range of commercially viable water mining treatment technologies are now available to treat sewage to specified water quality targets. Most of these technologies have minimal plant footprint requirements, making them suitable for decentralised operations. This paper discusses a hybrid water mining system that includes chemically assisted fine solids separation followed by a biological treatment process. Results from the first proof testing of this water mining system in Sydney, Australia are presented. The results confirm the suitability of the hybrid system for producing high-quality water for non-potable reuse.

Rainwater tanks have been an integral part of the Australian landscape given the vital role these tanks have played over the years in rural Australia. In the past Local government and Water Authorities actively discouraged the use of rainwater tanks and informing citizens that they were illegal and dangerous. Kogarah Council within the Sydney metropolitan area is a proactive Council, and became the first council in Sydney to adopt Total Water Cycle Management (TWCM) principles into its Sustainability Management Plan, integrating these principles into on-ground projects at a catchment level in a planned and strategic approach. Among it priority projects was the Rainwater Tanks in Schools. This paper outlines how this project assisted all 22 schools in the Kogarah LGA (The Local Government Association) to increase the efficiency of water use and install rainwater tanks to reduce potable water use in toilet flushing and irrigating school gardens. The rainwater harvesting reduced the amount of drinking water used for toilet flushing and/or irrigation. The rainwater tanks also act as a visual reminder to conserve water for the students. The project has equipped the next generation with the necessary tools to make informed decisions and undertake actions that will move towards achieving sustainability.

Electroencephalography (EEG) has been widely adopted to monitor changes in cognitive states, particularly stages of sleep, as EEG recordings contain a wealth of information reflecting changes in alertness and sleepiness. In this study, silicon dry electrodes based on Micro-Electro-Mechanical Systems (MEMS) were developed to bring high-quality EEG acquisition to operational workplaces. They have superior conductivity performance, large signal intensity, and are smaller in size than conventional (wet) electrodes. An EEG-based drowsiness estimation system consisting of a dry-electrode array, power spectrum estimation, principal component analysis (PCA)-based EEG signal analysis, and multivariate linear regression was developed to estimate drivers’ drowsiness levels in a virtual-reality-based dynamic driving simulator. The proposed system can help elders who are often affected by periods of tiredness and fatigue.

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, where multi-attribute nodes represent tuples, and edges represent primary key and foreign key references among nodes. 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 to 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. We present our findings in this paper. © 2010 Springer Science + Business Media, LLC & Science Press, China.

One-way quantum computing achieves the full power of quantum computation by performing single particle measurements on some many-body entangled state, known as the resource state. As single particle measurements are relatively easy to implement, the preparation of the resource state becomes a crucial task. An appealing approach is simply to cool a strongly correlated quantum many-body system to its ground state. In addition to requiring the ground state of the system to be universal for one-way quantum computing, we also want the Hamiltonian to have non-degenerate ground state protected by a fixed energy gap, to involve only two-body interactions, and to be frustration-free so that measurements in the course of the computation leave the remaining particles in the ground space. Recently, significant efforts have been made to the search of resource states that appear naturally as ground states in spin lattice systems. The approach is proved to be successful in spin-5/2 and spin-3/2 systems. Yet, it remains an open question whether there could be such a natural resource state in a spin-1/2, i.e., qubit system. Here, we give a negative answer to this question by proving that it is impossible for a genuinely entangled qubit states to be a non-degenerate ground state of any two-body frustration-free Hamiltonian. What is more, we prove that every spin-1/2 frustration-free Hamiltonian with two-body interaction always has a ground state that is a product of single- or two-qubit states, a stronger result that is interesting independent of the context of one-way quantum computing.

The tensor rank (also known as generalized Schmidt rank) of multipartite pure states plays an important role in the study of entanglement classifications and transformations. We employ powerful tools from the theory of homogeneous polynomials to investigate the tensor rank of symmetric states such as the tripartite state $\ket{W_3}=\tfrac{1}{\sqrt{3}}(\ket{100}+\ket{010}+\ket{001})$ and its $N$-partite generalization $\ket{W_N}$. Previous tensor rank estimates are dramatically improved and we show that (i) three copies of $\ket{W_3}$ has rank either 15 or 16, (ii) two copies of $\ket{W_N}$ has rank $3N-2$, and (iii) $n$ copies of $\ket{W_N}$ has rank O(N). A remarkable consequence of these results is that certain multipartite transformations, impossible even probabilistically, can become possible when performed in multiple copy bunches or when assisted by some catalyzing state. This effect is impossible for bipartite pure states.

The tensor rank (also known as generalized Schmidt rank) of multipartite pure states plays an important role in the study of entanglement classifications and transformations. We employ powerful tools from the theory of homogeneous polynomials to investigate the tensor rank of symmetric states such as the tripartite state |W3=1√3(|100+|010+|001) and its N-partite generalization |WN. Previous tensor rank estimates are dramatically improved and we show that (i) three copies of |W3 have a rank of either 15 or 16, (ii) two copies of |WN have a rank of 3N-2, and (iii) n copies of |WN have a rank of O(N). A remarkable consequence of these results is that certain multipartite transformations, impossible even probabilistically, can become possible when performed in multiple-copy bunches or when assisted by some catalyzing state. This effect is impossible for bipartite pure states. © 2010 The American Physical Society.

Background. Prediction of long-range inter-residue contacts is an important topic in bioinformatics research. It is helpful for determining protein structures, understanding protein foldings, and therefore advancing the annotation of protein functions. Results. In this paper, we propose a novel ensemble of genetic algorithm classifiers (GaCs) to address the long-range contact prediction problem. Our method is based on the key idea called sequence profile centers (SPCs). Each SPC is the average sequence profiles of residue pairs belonging to the same contact class or non-contact class. GaCs train on multiple but different pairs of long-range contact data (positive data) and long-range non-contact data (negative data). The negative data sets, having roughly the same sizes as the positive ones, are constructed by random sampling over the original imbalanced negative data. As a result, about 21.5% long-range contacts are correctly predicted. We also found that the ensemble of GaCs indeed makes an accuracy improvement by around 5.6% over the single GaC. Conclusions. Classifiers with the use of sequence profile centers may advance the long-range contact prediction. In line with this approach, key structural features in proteins would be determined with high efficiency and accuracy. © 2010 Li and Chen; licensee BioMed Central Ltd.

Protein domains are structural and fundamental functional units of proteins. The information of protein domain boundaries is helpful in understanding the evolution, structures and functions of proteins, and also plays an important role in protein classification. In this paper, we propose a support vector regression-based method to address the problem of protein domain boundary identification based on novel input profiles extracted from AA-index database. As a result, our method achieves an average sensitivity of ∼36.5% and an average specificity of ∼ 81% for multi-domain protein chains, which is overall better than the performance of published approaches to identify domain boundary. As our method used sequence information alone, our method is simpler and faster.© Springer-Verlag 2010.

Measurement based quantum computation (MBQC), which requires only single particle measurements on a universal resource state to achieve the full power of quantum computing, has been recognized as one of the most promising models for the physical realization of quantum computers. Despite considerable progress in the last decade, it remains a great challenge to search for new universal resource states with naturally occurring Hamiltonians, and to better understand the entanglement structure of these kinds of states. Here we show that most of the resource states currently known can be reduced to the cluster state, the first known universal resource state, via adaptive local measurements at a constant cost. This new quantum state reduction scheme provides simpler proofs of universality of resource states and opens up plenty of space to the search of new resource states, including an example based on the one-parameter deformation of the AKLT state studied in [Commun. Math. Phys. 144, 443 (1992)] by M. Fannes et al. about twenty years ago.

This paper considers a berth allocation problem (BAP) which requires the determination of exact berthing times and positions of incoming ships in a container port. The problem is solved by optimizing the berth schedule so as to minimize concurrently the three objectives of makespan, waiting time, and degree of deviation from a predetermined priority schedule. These objectives represent the interests of both port and ship operators. Unlike most existing approaches in the literature which are single-objective-based, a multi-objective evolutionary algorithm (MOEA) that incorporates the concept of Pareto optimality is proposed for solving the multi-objective BAP. The MOEA is equipped with three primary features which are specifically designed to target the optimization of the three objectives. The features include a local search heuristic, a hybrid solution decoding scheme, and an optimal berth insertion procedure. The effects that each of these features has on the quality of berth schedules are studied. © 2008 Springer Science+Business Media, LLC.

In this study, different processes such as flocculation with ferric chloride (FeCl3) and deep bed filtration (sand filtration and dual media filtration) as a pre-treatment to microfiltration (MF) were used for seawater desalination. The performance of these pre-treatments was determined in terms of silt density index (SDI) and modified fouling index (MFI) and flux decline in MF. Flux decline of MF with seawater was 45% without any pre-treatment, 42% after pre-treatment of FeCl3 flocculation, 24% after pre-treatment of sand filtration with in-line coagulation and 22% after pre-treatment of dual media filtration (sand and anthracite), respectively. MFI and SDI also indicated that deep bed filtration with in-line flocculation was better pretreatment than flocculation alone. Detailed molecular weight distribution (MWD) of seawater organic matter was examined after different pretreatments. MWD of the initial seawater mainly ranged from 1510 Da to 130 Da. Deep bed filtration with in-line flocculation removed relatively large molecular weight of organic matter (1510â1180 Da), while the small molecular weights (less than 530 Da) were not removed.

The performance of these pre-treatments was determined in terms of silt density index (SDI) and modified fouling index by using microfilter (MF-MFI), ultrafilter (UF-MFI), and nanofi lter (NF-MFI) membrane. MFI and SDI indicated that deep bed filtration with in-line flocculation was better pre-treatment than flocculation alone as colloidal particles are removed after this pretreatment. UF-MFI and NF-MFI indicated that these pretreatment cannot remove dissolved organic matter as the fouling reduction was smaller.

Sensor Actor Network Modeling utilizing the Holonic Architectural FrameworkThis paper discusses the results of utilizing advanced EKM modeling techniques to manage Sensor-Actor networks (SANETs) based upon the Holonic Architectural Framework. EKMs allow a quantitative analysis of an algorithmic artificial neural network process by using an indirect-mapping EKM to self-organize from a given input space to administer SANET routing and clustering functions with a control parameter space. Results demonstrate that in comparison to linear approximation techniques, indirect mapping with EKMs provide fluid control and feedback mechanisms by operating in a continuous sensory control space - thus enabling interactive detection and optimization of events in real-time environments.

AbstractAim:  To compare the mortality, morbidity of emergency and elective cesarean section with vaginal delivery among Asian teaching hospitalsMethods:  Hospital based prospective study at 12 centers of 9 countries.Results:  12 591 vaginal deliveries, 3062 elective and 4328 emergency cesarean section were followed up to 5 days postpartum. Maternal deaths (95% CI) per 1000 births among vaginal deliveries being 0.47 (0.17, 1.03) was not significantly different from 0.31 (0.01, 1.73) of elective cesarean section and both rates were significantly lower than 2.87 (1.53, 4.91) per 1000 births of emergency section. The vaginal delivery group had significantly lower incidences of all major complication except significantly higher chance of secondary operations and non‐significantly different risk for endometritis. Corresponding neonatal mortality per 1000 deliveries among the three groups were 7 (5.6, 8.6), 2.2 (0.9, 4.6) and 12.4 (9.3, 16.2) (P < 0.001). Vaginal delivery also had higher rates of severe asphyxia and palsy than elective cesarean section.Conclusion:  Maternal complications were increased by cesarean delivery but elective section may reduce neonatal complication.

An excel-based model was developed to evaluate economic and environmental benefits of the solar-powered compaction garbage bins in public areas in Australia. Input data were collected from Brisbane and Wollongong City councils, and Sydney Olympic Park. The results demonstrate that solar-powered compaction garbage bins would provide environmental benefits in all scenarios. However, results of the economic analysis of the three studied areas varied significantly. The unique situation of Sydney Olympic Park made implementation in that facility particularly appealing. A lower monthly rental cost is needed for the implementation of this novel waste management practice.

This paper presents a vibration-based damage identification method that utilises a âdamage fingerprint❠of a structure in combination with Principal Component Analysis (PCA) and neural network techniques to identify defects. The Damage Index (DI) method is used to extract unique damage patterns from a damaged beam structure with the undamaged structure as baseline. PCA is applied to reduce the effect of measurement noise and optimise neural network training. PCA-compressed DI values are, then, used as inputs for a hierarchy of neural network ensembles to estimate locations and severities of various damage cases. The developed method is verified by a laboratory structure and numerical simulations in which measurement noise is taken into account with different levels of white Gaussian noise added. The damage identification results obtained from the neural network ensembles show that the presented method is capable of overcoming problems inherent in the conventional DI method. Issues associated with field testing conditions are successfully dealt with for numerical and the experimental simulations. Moreover, it is shown that the neural network ensemble produces results that are more accurate than any of the outcomes of the individual neural networks.

We consider the scenario in which Alice transmits private classical messages to Bob via a classical-quantum channel, part of whose output is intercepted by an eavesdropper, Eve. We prove the existence of a universal coding scheme under which Alice's messages can be inferred correctly by Bob, and yet Eve learns nothing about them. The code is universal in the sense that it does not depend on specific knowledge of the channel. Prior knowledge of the probability distribution on the input alphabet of the channel, and bounds on the corresponding Holevo quantities of the output ensembles at Bob's and Eve's end suffice.

Environmental performance of residential development has played an important role in achieving the goal of sustainable construction. Green homes have been or are being built in many countries. This paper discusses the issues of sustainability and its roles in residential developments. This paper also examines the development of a building and sustainability index (BASIX) for mandatory assessments of all residential developments in New South Wales (NSW), Australia. Data collection includes examining the methodology of BASIX in assessing sustainability performance of residential development in the three broad areas of energy and water efficiency as well as indoor thermal comfort. The introduction of BASIX has had a profound impact on the construction industry. An online survey of users of BASIX in the construction industry revealed that the tool has played a significant role in providing a guideline for the sustainability performance of a proposed development and lifting the standard of design practices. The tool has led to better thermal comfort for users and reduced water and energy consumption by all new residential developments in NSW. However successful this has been, there is more to be done such as control of waste and energy usage in the manufacturing of building materials.

Existing environmental performance assessment approaches focus on the overall performance to reflect sustainability of built projects. However, the impacts caused by construction activities on the environment occur throughout a project's life cycle which may be different at different stages. Similarly, the economic benefits and social impacts from implementing a construction project may also be different in different project stages. This paper presents a model of the sustainable development value (SDV), which integrates sustainability assessment into the building process. SDV measures the significance of the concerned project to the attainment of sustainable development value at different stages of a building life cycle, and the SDV at each stage will be amalgamated into the model of sustainable development ability (SDA). SDA is used as a prototype to demonstrate the extent of sustainable performance to aid decision making. This paper presents the methodological framework of SDV and SDA, and the implementation was demonstrated using a case study. Copyright © 2010 Inderscience Enterprises Ltd.

Abstract MicroRNAs (miRNAs) act at the posttranscriptional level to control gene expression in virtually every biological process, including oncogenesis. Here, we report the identification of a set of miRNAs that are differentially regulated in childhood adrenocortical tumors (ACT), including miR-99a and miR-100. Functional analysis of these miRNAs in ACT cell lines showed that they coordinately regulate expression of the insulin-like growth factor–mammalian target of rapamycin (mTOR)–raptor signaling pathway through binding sites in their 3′-untranslated regions. In these cells, the active Ser2448-phosphorylated form of mTOR is present only in mitotic cells in association with the mitotic spindle and midbody in the G2-M phases of the cell cycle. Pharmacologic inhibition of mTOR signaling by everolimus greatly reduces tumor cell growth in vitro and in vivo. Our results reveal a novel mechanism of regulation of mTOR signaling by miRNAs, and they lay the groundwork for clinical evaluation of drugs inhibiting the mTOR pathway for treatment of adrenocortical cancer.

Direct involvement of the user in the assembling process of his/her own products or even entire house is a reality among low-income populations in developing countries. Nevertheless, there are a limited number of products that have actually been designed from a do-it-yourself (DIY) perspective, which results in several problems, such as poor user safety while the product is being assembled or inadequate results from an improvised assembling. Hence, the main goal of this paper is to analyse barriers to and opportunities for developing DIY products for low-income housing in developing countries. The research method utilises a case study of a DIY product consisting of a hybrid solution that acted as both a partition wall and a wardrobe. The identified opportunities included more systematic use of existing craft competencies among low-income families and the possibility of cost reduction through DIY concepts. Major barriers included the perception of the DIY product as inferior and the difficulty of communicating the DIY assembly process to users who quite often are illiterate.

Abstract Background Genetic as well as epigenetic alterations are a hallmark of both epithelial and haematological malignancies. High throughput screens are required to identify epigenetic markers that can be useful for diagnostic and prognostic purposes across malignancies. Results Here we report for the first time the use of the MIRA assay (methylated CpG island recovery assay) in combination with genome-wide CpG island arrays to identify epigenetic molecular markers in childhood acute lymphoblastic leukemia (ALL) on a genome-wide scale. We identified 30 genes demonstrating methylation frequencies of ≥25% in childhood ALL, nine genes showed significantly different methylation frequencies in B vs T-ALL. For majority of the genes expression could be restored in methylated leukemia lines after treatment with 5-azaDC. Forty-four percent of the genes represent targets of the polycomb complex. In chronic myeloid leukemia (CML) two of the genes, (TFAP2A and EBF2), demonstrated increased methylation in blast crisis compared to chronic phase (P < 0.05). Furthermore hypermethylation of an autophagy related gene ATG16L2 was associated with poorer prognosis in terms of molecular response to Imatinib treatment. Lastly we demonstrated that ten of these genes were also frequently methylated in common epithelial cancers. Conclusion In summary we have identified a large number of genes showing frequent methylation in childhood ALL, methylation status of two of these genes is associated with advanced disease in CML and methylation status of another gene is associated with...

Producing a useful catalyst (TiO2) from sludge is possible after the incineration of sludge produced from the flocculation of wastewater by Ti-salts. In this study, TiO2 was successfully produced from dye wastewater sludge. Titanate nanotubes and nanoaggregates were produced through alkaline-hydrothermal and hydrogen peroxide treatments, respectively. Catalysts were characterised using scanning electron microscope and BET surface measurement. The photocatalytic activity was monitored for the photodegradation of organics in synthetic wastewater (SWW) and the photodecomposition of gas acetaldehyde. Nanotubes with a high surface area of 155.83 m2/g were obtained by alkaline-hydrothermal treatment, while lower surface area (65.22 m2/g) nanoaggregates were synthesized after hydrogen peroxide treatment. In general, nanoparticles, nanotubes and nanoaggregates showed mild photocatalytic activity. All catalysts showed similar photocatalytic activity for the photodecomposition of organics in SWW and the photodecomposition of acetaldehyde.

High technology and activity levels in the intensive care unit (ICU) lead to elevated and disturbing sound levels. As noise has been shown to affect the ability of patients to rest and sleep, continuous sound levels are required during sleep investigations. The aim of this pilot study was to develop a robust protocol to measure continuous sound levels for a larger more substantive future study to improve sleep for the ICU patient. A review of published studies of sound levels in intensive care settings revealed sufficient information to develop a study protocol. The study protocol resulted in 10 usable recordings out of 11 attempts to collect pilot data. The mean recording time was 17.49 ± 4.5 h. Sound levels exceeded recommendations made by the World Health Organization (WHO) for hospitals. The mean equivalent sound level (LAeq) was 56.22 ± 1.65 dB and LA90 was 46.8 ± 2.46 dB. The data reveal the requirement for a noise reduction program within this ICU.

Hybrid membrane filtration processes involve complex physical, chemical and biological phenomena, thus their mechanistic modelling is challenging. The chief advantages of statistical and artificial neural networks (ANN) models (data-driven models) are that they do not require assumptions and simplifications to establish relationships from data. This paper investigates the characteristics and performance of several data-driven methods to model a hybrid membrane system. The focus is on the application of regression analysis and artificial intelligence based methods to a steady-state system. Among empirically based approaches, ANN neural networks methods were found to be very useful to predict permeate quality and membrane fouling. In the past multivariate nonlinear regression had barely been investigated for process modelling in water and waste water treatment. In this study polynomial multivariate nonlinear regression showed a superior performance. Multivariate parametric nonlinear models could match the performance of the nonparametric ANN models in the empirical modelling of complex systems, especially when combined with advanced optimization methods. This paper gives the methodology of how one could optimize a membrane hybrid system using ANN, validating it with one set of data. The same procedure/methodology can be applied to similar systems.

Bioengineering features of native vegetation are currently being evolved to enhance soil stiffness, slope stabilisation and erosion control. The effects of tree roots on soil moisture content and ground settlement are discussed in this paper. Matric suction induced by tree roots is a key factor, governing the properties of unsaturated soils, directly imparting stability to slopes and resistance for yielding behaviour. A mathematical model for the rate of root water uptake that considers ground conditions, type of vegetation and climatic parameters has been developed. This study highlights the inter-related parameters contributing to the development of a conceptual evapo-transpiration and root moisture uptake equilibrium model that is then incorporated in a comprehensive numerical finite element model. The developed model considers fully coupled-flow-deformation behaviour of soil. Field measurements obtained by the Authors from a site in Victoria, South of Australia, are used to validate the model. In this study, the active tree root distribution has been predicted by measuring soil organic content distribution. The predicted results show acceptable agreement with the field data in spite of the assumptions made for simplifying the effects of soil heterogeneity and anisotropy. The results prove that the proposed root water uptake model can reliably predict the region of the maximum matric suction away from the tree axis. © 2009 Elsevier B.V. All rights reserved.

The optical properties of quantum dots have a close relationship with the size fluctuation，density，strain filed distribution of the dots and the spacer layer thickness. InAs/GaAs quantum dot with GaNXAs1-X strain compensation layers （SCL） is theoretically investigated for improving the crystal quality. The reduction effects of the spacer thickness are discussed quantitatively. The influence of the location and the N concentration of the GaNXAs1-X SCL on compensation of the strain formed on quantum dots （QDs） and the system is also discussed. The reduction effect of SCL on strain of system is analyzed and the vertical alignment probability between the adjacent layers is calculated. Our results can provide a theoretical basis for finding the optimal properties of SCL to realize the high quality multi-QD layer.

This article comprises a review of both the quasi-probability representations of infinite-dimensional quantum theory (including the Wigner function) and the more recently defined quasi-probability representations of finite-dimensional quantum theory. We focus on both the characteristics and applications of these representations with an emphasis toward quantum information theory. We discuss the recently proposed unification of the set of possible quasi-probability representations via frame theory and then discuss the practical relevance of negativity in such representations as a criteria for quantumness.

AbstractWe evaluated the self‐assembly properties of uniluminal vascular spheroids having outer layers of vascular smooth muscle cells and a contiguous inner layer of endothelial cells lining a central lumen. We showed that while pairs of uniluminal vascular spheroids suspended in culture medium fused to form a larger diameter spheroidal structure, spheroids in collagen hydrogels formed elongated structures. These findings highlight the potential use of uniluminal vascular spheroids as modules to engineer blood vessels. We also demonstrate that uniluminal vascular spheroid fusion conforms to models describing the coalescence of liquid drops. Furthermore, the fusion of uniluminal vascular spheroids in vitro closely resembled the in vivo process by which the descending aorta forms from the fusion of the paired dorsal aortae during embryonic development. Together, the findings indicate that tissue liquidity underlies uniluminal vascular spheroid fusion and that in vivo anastomosis of blood vessels may involve a similar mechanism.

External cognition concerns knowledge that is embedded in our everyday lives and environment. One type of knowledge is memories, recollections of events that occurred in the past. So how do we remember them? One way this can be done is through cuing and reconstructing. These cues can be internal, in our minds, or in our everyday environment. In this paper we look at memory cues in our environment by comparing the effect of cue modality (odor, physical artifact, photo, sound, and video) on the number of memory details people had from a unique one-day real-life event. Contrary to expectation, the no-cue condition (in effect, only a question asking the participants to write down their memories) created on average significantly more memory-details than the cued conditions.

The wear and creep characteristics of highly crosslinked ultrahigh-molecular-weight polyethylene (UHMWPE) articulating against large-diameter (36 mm) ceramic and cobalt chrome femoral heads have been investigated in a physiological anatomical hip joint simulator for 10 million cycles. The crosslinked UHMWPE/ceramic combination showed higher volume deformation due to creep plus wear during the first 2 million cycles, and a steady-state wear rate 40 per cent lower than that of the crosslinked UHMWPE/cobalt chrome combination. Wear particles were isolated and characterized from the hip simulator lubricants. The wear particles were similar in size and morphology for both head materials. The particle isolation methodology used could not detect a statistically significant difference between the particles produced by the cobalt chrome and alumina ceramic femoral heads.

Bilevel-programming techniques are developed to handle decentralized problems with two-level decision makers, which are leaders and followers, who may have more than one objective to achieve. This paper proposes a λ-cut and goal-programming-based algorithm to solve fuzzy-linear multiple-objective bilevel (FLMOB) decision problems. First, based on the definition of a distance measure between two fuzzy vectors using λ-cut, a fuzzy-linear bilevel goal (FLBG) model is formatted, and related theorems are proved. Then, using a λ-cut for fuzzy coefficients and a goal-programming strategy for multiple objectives, a λ-cut and goal-programming-based algorithm to solve FLMOB decision problems is presented. A case study for a newsboy problem is adopted to illustrate the application and executing procedure of this algorithm. Finally, experiments are carried out to discuss and analyze the performance of this algorithm. © 2006 IEEE.

A new method is presented to design dual-band, high- directivity, EBG-resonator antennas using simple, single-resonant, single-layer partially reflective surfaces (PRS). The large, positive gradient of the reflection phase versus frequency curve of partially reflecting surfaces, observed only close to the resonance frequency of the PRS, is exploited for this purpose. An example single-resonant PRS, based on a frequency-selective surface (FSS) composed of a printed slot array, was designed. Then it is used to design an EBG- resonator antenna to demonstrate the feasibility of achieving dual-band performance. Cavity models are employed, together with the reflection characteristics of the PRS, to understand the operation of the device at critical frequencies such as cavity resonance frequencies and the PRS resonance frequency. Antenna simulations and computed results confirm the dual-band operation of this very simple, single-layer, low- profile EBG-resonator antenna. It resonates in two bands centered at 10.5 GHz and 12.3 GHz. The peak directivity in each band is 18.2 dBi and 20.5 dBi, and the 3 dB directivity bandwidth of each band is 7.5% and 8.7%, respectively.

View description>>

In order to make full utilization of the scarce spectrum resources for Cognitive radio networks, secondary users are expected to exploit the available spectrum of primary users. However, when there are several spectrum bands 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 spectrum characterization parameters, in particular, the primary users' arrival probability, to estimate the quality of the available spectrum bands. A weight auto-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.

Most work on multi-biometric fusion is based on static fusion rules. One prominent limitation of static fusion is that it cannot respond to the changes of the environment or the individual users. This paper proposes context-aware multi-biometric fusion, which can dynamically adapt the fusion rules to the real-time context. As a typical application, the context-aware fusion of gait and face for human identification in video is investigated. Two significant context factors that may affect the relationship between gait and face in the fusion are considered, i.e., view angle and subject-to-camera distance. Fusion methods adaptable to these two factors based on either prior knowledge or machine learning are proposed and tested. Experimental results show that the context-aware fusion methods perform significantly better than not only the individual biometric traits, but also those widely adopted static fusion rules including SUM, PRODUCT, MIN, and MAX. Moreover, context-aware fusion based on machine learning shows superiority over that based on prior knowledge. © 2010 Elsevier Ltd. All rights reserved.

In this paper, we develop a new decision making model and apply it in political management. We use a framework based on the use of ideals in the decision process and several similarity measures such as the Hamming distance, the adequacy coefficient and the index of maximum and minimum level. For each similarity measure, we use different types of aggregation operators such as the simple average, the weighted average, the ordered weighted averaging (OWA) operator and the generalized OWA (GOWA) operator. This new approach considers several attributes and different scenarios that may occur in the uncertain environment. We see that depending on the particular type of aggregation operator used the results may lead to different decisions. © 2010 Springer-Verlag Berlin Heidelberg.

This paper presents a method based on Current Hoop Model for the analysis and design of induction coilgun. The cylindrically symmetric armature is subdivided into concentric hoops with diverse rectangular crosssections, in each of which the current is assumed to be uniformly distributed. An equivalent analytical model considering mutual coupling of coils and armature hoops is constructed for dynamic simulation of the coilgun. Based on this model, the selfand mutualinductances of exciting winding and hoops are calculated by Neumann method. The circuit equations are solved coupled with the equation of motion of projectile by using the Treanor method to ensure the convergence. Comparison between the experimental results and the numerical results simulated by Finite Element method (FEM) shows the validity of the presented simulation method for coilgun. The optimization of a sixstage coilgun is achieved by employing the genetic algorithm (GA).

The sponge volume had significant impact on phosphorus removal rather than organic or nitrogen removal, and 20% volume of sponge could achieve 100% T-P removal within 3 h in a sponge batch reactor (SBR).

This study aims at evaluating the impacts of flocculant addition to a submerged membrane bioreactor (SMBR). Three types of common flocculants (FeCl3, PACl and chitosan) were tested based on the performance of organic and nutrients removal, respiration test and fouling control. The data showed that all of the flocculants not only could keep high removal efficiencies of DOC and COD (>90%) compared to SMBR alone, but also exhibited different advantages and disadvantages according to the properties of the flocculants. For instance, inorganic flocculants strongly affected the nitrification process and organic flocculant addition slightly reduced the phosphorus removal efficiency in SMBR. After adding FeCl3 and PACl, NH4-N removal decreased to 31.9% and 11.1%, while T-N removal dropped to 22% and 0.5% respectively. Although flocculants addition improved sludge settleability and oxygen transfer to some extent, organic flocculant obtained more stable sludge volume indexes (SVI) and specific oxygen uptake rates (SOUR) than those of inorganic flocculants. Inorganic flocculants, on the other hand, led to more reduction of soluble microbial products (SMP) present in mixed liquor and lower membrane fouling rates (1.3 and 2.6 kPa/day for FeCl3 and PACl respectively). © 2009 Elsevier B.V.

In this study, short-term experiments were conducted with different configurations of membrane hybrid systems to treat biological treated sewage effluent containing refractory organic pollutants: (i) submerged hollow fiber microfiltration (SMF) alone; (ii) spiral flocculator (SF)-SMF without settling; (iii) SF-PAC-SMF without settling and (iv) SMF with magnetic ion exchange resin MIEXw pretreatment. The results indicated that the pre-flocculation of SF could improve the mitigation of membrane fouling significantly even when the system was operated at a high membrane filtration rate. The transmembrane pressure (TMP) of SF-PAC-SMF only increased marginally (0.8 kPa over 8 hours). SF-SMF without the addition of powdered activated carbon (PAC) also took a relatively long duration for the TMP to increase. The TMP only increased by 2.5 kPa over 8 hours. The SF-PAC-MF system resulted in a high dissolved organic carbon (DOC) removal of more than 96%. When used as pre-treatment to submerged membranes, the fluidized bed MIEXw contactor could remove a significant amount of organic matter in wastewater. This pre-treatment helped to reduce the membrane fouling and kept the TMP low during the membrane operation.

Energy crisis has made it urgent to find alternative energy sources for sustainable energy supply; wind energy is one of the attractive alternatives. Within a wind energy system, the wind speed is one key parameter; accurately forecasting of wind speed can minimize the scheduling errors and in turn increase the reliability of the electric power grid and reduce the power market ancillary service costs. This paper proposes a new hybrid model for long-term wind speed forecasting based on the first definite season index method and the Autoregressive Moving Average (ARMA) models or the Generalized Autoregressive Conditional Heteroskedasticity (GARCH) forecasting models. The forecasting errors are analyzed and compared with the ones obtained from the ARMA, GARCH model, and Support Vector Machine (SVM); the simulation process and results show that the developed method is simple and quite efficient for daily average wind speed forecasting of Hexi Corridor in China.

This paper presents a case study on streamf ow data preparation for a regional f ood frequency analysis (RFFA) project for the states of Victoria and NSW, in connection with the forthcoming edition of Australian Rainfall and Runoff. The study gathered annual maximum f ood series data for a large number of stations from Victoria and NSW, and applied various statistical techniques to prepare the f nal data set. It was found that a large primary data set, even if selected using a fairly stringent set of criteria, cannot guarantee a similarly large f nal data set, as streamf ow data are affected by many sources of uncertainty. The trade-offs between quality and quantity are discussed and illustrated. The maximum rating ratio, def ned as the ratio of the largest estimated f ow and the maximum measured f ow at a gauging station, is used to identify stations whose quantiles may be seriously affected by rating curve errors. In a case study involving Victorian stations, the importance of maintaining a high spatial coverage of stations was demonstrated. It was shown that a 50% reduction in the number of stations used in a RFFA resulted in an increase of the standard error of prediction of f ood quantiles up to 90%. © Institution of Engineers Australia, 2010.

This paper proposes a novel mechanism for the initial alignment of low-cost INS aided by GPS. For low-cost INS, the initial alignment is still a challenging issue because of the high noises from low-cost inertial sensors. In this paper, a two-stage Kalman Filtering mechanism is proposed for the initial alignment of low-cost INS. The first stage is designed for the coarse alignment. To solve the problems encountered by the general coarse alignment approach, an INS error dynamic accounting for unknown initial heading error is developed, and the corresponding observation equation, taking into account the unknown heading error, is also developed. The second stage is designed for the fine alignment, where the classical INS error dynamics based on small attitude error is used. Experimental results indicate that the proposed alignment approach can complete the initial alignment more quickly and more accurately compared with the conventional approach.

Structural reliability analyses are commonly applied to estimation of probabilities of structural damage to static and dynamic loads such as earthquake, wind and wave loads. Although blast loadings acting on structures from accidental explosions or hostile bombings are very difficult to be accurately predicted owing to many uncertain parameters that influence explosion shock wave propagation and shock wave interaction with structures, reliability analyses of structural failure to blast loadings with consideration of uncertainties in blast loading and structural parameters are very limited. Instead, a large safety factor is usually used to account for uncertain variations in blast loading and structural parameters in blast-resistant design and analysis. This may lead to an inaccurate design of structures to resist blast loads, and an inaccurate assessment of structure performance in a given explosion scenario. In this study, reliability analyses of three example RC columns to randomly varying blast loads are carried out. The column dimensions, reinforcement ratios and material strengths are assumed to be normally distributed with the respective design parameters as the mean values. The mean value and standard deviation of the peak reflected pressure and duration of the blast load at various scaled distances are derived from available empirical formulae, and are used in this study to model the blast pressure variations. Failure probabilities of the example RC columns subjected to blast loads of different scaled distances are estimated. Numerical results are compared with those obtained with the deterministic blast loading or deterministic column property assumptions. The importance of considering the random variations of structural properties and blast loadings in assessing the blast load effects on RC columns is discussed.

For more effective use of ground fresh water resources, a remote sensing and GIS have been used in many places in last decades. The digital topographic maps in scale 1:25000 within GIS environment have been studied to observe the risk reduction and changing of the water resources because of the tectonic activities which are crucial to generate a groundwater disaster in the study area. The area has been visually and digitally interpreted to delineate DEM, drainage network, drainage basin, karst landforms, lineaments and lithology for ground water reduction and possible new locations to explore and reduce the risk reduction and disasters. Image elements are used during visual and digital interpretation. Extensive field works have been attempted using global positioning system (GPS) to collect water samples. The study shows that the groundwater is controlled by geomorphology, landslides, lineament analysis, lithology and topography in the study area. This study shows the advantages of remote sensing and GIS techniques for Karst and water resources study. Use of GIS-technologies makes it possible to construct 3D models of river basins and adjust theoretical reserves of the deposits.

An integration of photocatalysis with low-pressure submerged membrane has attracted growing interest for its synergic advantages in water and wastewater treatment. In this study, the adsorption and photocatalytic oxidation of organic compounds by UV light responsive titanium dioxide (TiO2) were investigated. First, the adsorption behavior of the TiO2 was examined by the adsorption isotherm and kinetics experiments. The photocatalytic reactivity of the catalysts was then compared at different operating conditions. The results indicate that the Freundlich model described well the adsorption capacity of both materials. The photocatalytic kinetics showed that the highest removal of effluent organic matter (EfOM) was achieved at an optimum concentration of 1.0 g/L of TiO2. In addition, it was found that the pre-photosensitization with titanium dioxide/ultra-voilet radiation (TiO2/UV) could effectively reduce membrane fouling and enhance the permeate flux of the submerged membrane reactor when it was used as a post-treatment. An increase of 10% in organic removal efficiency was achieved by the posttreatment of membrane filtration. The sustainable flux of the membrane reactor increased from 25 up to 40 L/m2.h when the pretreatment of photocatalysis was used.

Women have a strong need to be involved in their own maternity care. Pregnancy hand-held records encourage women's participation in their maternity care; gives them an increased sense of control and improves communication among care providers. They have been successfully used in the UK and New Zealand for almost 20 years. Despite evidence that supports the use of hand-held records, widespread introduction has not occurred in Australia. The need for an electronic version of pregnancy hand-held records has become apparent, especially after the introduction of the Electronic Medical Record in Australia. A personal digital assistant (PDA) was developed as an interactive antenatal electronic maternity record that health-care providers could use in any setting and women could access using the internet. This article will describe the testing of the antenatal electronic maternity record.

It has been widely assumed that for a given BMI, Asians have higher percent body fat (PBF) than whites, and that the BMI threshold for defining obesity in Asians should be lower than the threshold for whites. This study sought to test this assumption by comparing the PBF between US white and Vietnamese women. The study was designed as a comparative cross‐sectional investigation. In the first study, 210 Vietnamese women ages between 50 and 85 were randomly selected from various districts in Ho Chi Minh City (Vietnam). In the second study, 419 women of the same age range were randomly selected from the Rancho Bernardo Study (San Diego, CA). In both studies, lean mass (LM) and fat mass (FM) were measured by dual‐energy X‐ray absorptiometry (DXA) (QDR 4500; Hologic). PBF was derived as FM over body weight. Compared with Vietnamese women, white women had much more FM (24.8 ± 8.1 kg vs. 18.8 ± 4.9 kg; P < 0.0001) and greater PBF (36.4 ± 6.5% vs. 35.0 ± 6.2%; P = 0.012). However, there was no significant difference in PBF between the two groups after matching for BMI (35.1 ± 6.2% vs. 35.0 ± 5.7%; P = 0.87) or for age and BMI (35.6 ± 5.1% vs. 35.8 ± 5.9%; P = 0.79). Using the criteria of BMI ≥30, 19% of US white women and 5% of Vietnamese women were classified as obese. Approximately 54% of US white women and 53% of Vietnamese women had their PBF >35% (P = 0.80). Although white women had greater BMI, body weight, and FM than Vietnamese women, their PBF was virtually identical. Further research is required to derive a more appropriate BMI threshold for defining obesity for Asian women.

Background: The relative contribution of lean and fat to the determination of bone mineral density (BMD) in postmenopausal women is a contentious issue. The present study was undertaken to test the hypothesis that lean mass is a better determinant of BMD than fat mass. Methods: This cross-sectional study involved 210 postmenopausal women of Vietnamese background, aged between 50 and 85 years, who were randomly sampled from various districts in Ho Chi Minh City (Vietnam). Whole body scans, femoral neck, and lumbar spine BMD were measured by DXA (QDR 4500, Hologic Inc., Waltham, MA). Lean mass (LM) and fat mass (FM) were derived from the whole body scan. Furthermore, lean mass index (LMi) and fat mass index (FMi) were calculated as ratio of LM or FM to body height in metre squared (m2). Results: In multiple linear regression analysis, both LM and FM were independent and significant predictors of BMD at the spine and femoral neck. Age, lean mass and fat mass collectively explained 33% variance of lumbar spine and 38% variance of femoral neck BMD. Replacing LM and FM by LMi and LMi did not alter the result. In both analyses, the influence of LM or LMi was greater than FM and FMi. Simulation analysis suggested that a study with 1000 individuals has a 78% chance of finding the significant effects of both LM and FM, and a 22% chance of finding LM alone significant, and zero chance of finding the effect of fat mass alone. Conclusions: These data suggest that both lean mass and fat mass are important determinants of BMD. For a given body size -- measured either by lean mass or height --women with greater fat mass have greater BMD.

Background: Recent in vitro evidence suggests a link between vitamin D status and the risk of tuberculosis (TB). This study sought to examine the association between vitamin D status, parathyroid hormone (PTH) and the risk of TB in a Vietnamese population. Methods: The study was designed as a matched case-control study, which involved 166 TB patients (113 men and 53 women), who were age-and-sex matched with 219 controls (113 men and 106 women). The average age of men and women was 49 and 50, respectively. TB was diagnosed by the presence of acid-fast bacilli on smears from sputum, and the isolation of M. tuberculosis. All patients were hospitalized for treatment in a TB specialist hospital. Controls were randomly drawn from the general community within the Ho Chi Minh, Vietnam. 25-hydroxyvitamin D [25(OH) D] and PTH was measured prior to treatment by an electrochemiluminescence immunoassay (ECLIA) on a Roche Elecsys. A serum level of 25(OH) D below 30 ng/mL was deemed to be vitamin D insufficient. Results: The prevalence of vitamin D insufficiency was 35.4% in men with TB and 19.5% in controls (P = 0.01). In women, there were no significant differences in serum 25(OH) D and serum PTH levels between TB patients and controls. The prevalence of vitamin D insufficiency in women with TB (45.3%) was not significantly different from those without TB (47.6%; P = 0.91). However, in both genders, serum calcium levels in TB patients were significantly lower than in non-TB individuals. Smoking (odds ratio [OR] 1.25; 95% confidence interval [CI] 1.10 - 14.7), reduced 25(OH) D (OR per standard deviation [SD]: 1.14; 95% CI 1.07 - 10.7) and increased PTH (OR per SD 1.13; 95% CI 1.05 - 10.4) were independently associated with increased risk of TB in men. Conclusion: These results suggest that vitamin D insufficiency was a risk factor for tuberculosis in men, but not in women. However, it remains to be established whether the association is a causal relationship.

This paper presents an algorithm to design a decentralized robust controller for static synchronous compensators (STATCOMs) using minimax linear quadratic output-feedback control design approach. There is an increase in the available (dynamic) transfer capability of power systems with fixed-speed wind generators due to the designed decentralized controllers. The effects of the integration of various types of wind generators into power systems based on transfer limit have also been analyzed in this paper. The effectiveness of the suggested control strategy is validated by simulations on a benchmark two area power system. The performance of the designed controller is also compared to a conventional proportional-integral-based STATCOM controller. Simulation results show that both the dynamic voltage stability and the transient stability can be improved by using the robust STATCOM control proposed in this paper.

AbstractThis study considers the use of artificial neural networks (ANNs) to predict the maximum dry density (MDD) and optimum moisture content (OMC) of soil‐stabilizer mix. Multilayer perceptron (MLP), one of the most widely used ANN architectures in the literature, is utilized to construct comprehensive and accurate models relating the MDD and OMC of stabilized soil to the properties of natural soil such as particle‐size distribution, plasticity, linear shrinkage, and the type and quantity of stabilizing additives. Five ANN models are constructed using different combinations of the input parameters. Two separate sets of ANN prediction models, one for MDD and the other for OMC, and also a combined ANN model for multiple outputs are developed using the potentially influential input parameters. Relative‐importance values of various inputs of the models are calculated to determine the significance of each of the predictor variables to MDD and OMC. Inferring the most relevant input parameters based on Garson's algorithm, modified ANN models are separately developed for MDD and OMC. The modified ANN models are utilized to introduce explicit formulations of MDD and OMC. A parametric study is also conducted to evaluate the sensitivity of MDD and OMC due to the variation of the most influencing input parameters. A comprehensive set of data including a wide range of soil types obtained from the previously published stabilization test results is used for training and testing the prediction models. The performance of ANN‐based models is subsequently analyzed and compared in detail. The results demonstrate that the accuracy of the proposed models is satisfactory as compared to the experimental results.

Free vibration analysis of annular moderately thick plates integrated with piezoelectric layers is investigated in this study for different combinations of soft simply supported, hard simply supported and clamped boundary conditions at the inner and outer edges of the annular plate on the basis of the Levinson plate theory (LPT). The distribution of electric potential along the thickness direction in the piezoelectric layer is assumed as a sinusoidal function so that the Maxwell static electricity equation is approximately satisfied. The differential equations of motion are solved analytically for various boundary conditions of the plate. In this study the closed-form solution for characteristic equations, displacement components of the plate and electric potential are derived for the first time in the literature. To demonstrate the accuracy of the present solution, comparison studies is first carried out with the available data in the literature and then natural frequencies of the piezoelectric coupled annular plate are presented for different thickness-radius ratios, inner-outer radius ratios, thickness of piezoelectric, material of piezoelectric and boundary conditions. Present analytical model provides design reference for piezoelectric material application, such as sensors, actuators and ultrasonic motors. © 2009 Elsevier Ltd. All rights reserved.

This paper employs an analytical method to analyze vibration of piezoelectric coupled thick annular functionally graded plates (FGPs) subjected to different combinations of soft simply supported, hard simply supported and clamped boundary conditions at the inner and outer edges of the annular plate on the basis of the Reddy’s third-order shear deformation theory (TSDT). The properties of host plate are graded in the thickness direction according to a volume fraction power-law distribution. The distribution of electric potential along the thickness direction in the piezoelectric layer is assumed as a sinusoidal function so that the Maxwell static electricity equation is approximately satisfied. The differential equations of motion are solved analytically for various boundary conditions of the plate. In this study closed-form expressions for characteristic equations, displacement components of the plate and electric potential are derived for the first time in the literature. The present analysis is validated by comparing results with those in the literature and then natural frequencies of the piezoelectric coupled annular FG plate are presented in tabular and graphical forms for different thickness-radius ratios, inner-outer radius ratios, thickness of piezoelectric, material of piezoelectric, power index and boundary conditions. © 2009 Elsevier Ltd.

In this study Free vibration analysis of vertical rectangular Mindlin plates resting on Pasternak elastic foundation and fully or partially in contact with fluid on their one side is investigated for different combinations of boundary conditions. The plate is assumed to be one of vertical rectangular walls of a container in contact with fluid. In order to analyze the interaction of the Mindlin plate with the elastic foundation and fluid system, three displacement components of the plate are expressed in the Ritz method by adopting a set of static Timoshenko beam functions satisfying geometric boundary conditions in a Cartesian co-ordinate system. The method of separation of variables and the method of Fourier series expansion is used to model fluid and to obtain the exact expression of the motion of fluid in the form of integral equations. The fluid domain is finite in depth and width but infinite in the length direction. To demonstrate the accuracy of the present solution, convergence study is first carried out and then a few comparison studies are carried out with the available data in the literature. Finally, natural frequencies of rectangular plates are presented in tabular and graphical forms for different fluid levels, foundation parameters, aspect ratios, thickness to width ratios and boundary conditions. © 2009 Elsevier Ltd.

This paper describes an approach to recognise and localise centres of mature lettuce heads in the field when the lettuce leaves obscure the distinctions between plants. This is of great value when using an automatic harvester in cluttered or closely planted vegetation. The aim of this work is to investigate and verify the potential use of spatial rather than visual clues for recognition and localisation, with a view to implement a more robust and sophisticated system if promise is shown. Colour/texture information was difficult to use so spatial information was used instead. A laser range finder was used to generate a height plot from above the plants. Lettuce examples were used to learn the radial distribution of the lettuce model. This was compared with the distributions of arbitrary locations in new scans to locate possible lettuce locations. Planting distance information was then used to localise the final lettuce positions. The algorithm was able to successfully locate 15 out of 16 sample lettuces. © 2010 Inderscience Enterprises Ltd.

Though the theory of quantum error correction is intimately related to the classical coding theory, in particular, one can construct quantum error correction codes (QECCs) from classical codes with the dual containing property, this does not necessarily imply that the computational complexity of decoding QECCs is the same as their classical counterparts. Instead, decoding QECCs can be very much different from decoding classical codes due to the degeneracy property. Intuitively, one expect degeneracy would simplify the decoding since two different errors might not and need not be distinguished in order to correct them. However, we show that general quantum decoding problem is NP-hard regardless of the quantum codes being degenerate or non-degenerate. This finding implies that no considerably fast decoding algorithm exists for the general quantum decoding problems, and suggests the existence of a quantum cryptosystem based on the hardness of decoding QECCs.

According to gun magnetorheological (MR) recoil damper's characteristics, aiming at the recoil part of a gun system under high impact and high-speed environment, the recoil resistance force's effect on the quiescence and firing stability of the gun was studied. The controllability of a magnetorheological damper to the gun recoil part's movement was also studied. A new gun magnetorheological recoil damper was designed and developed. And a suit of real-time measuring and controlling simulation experimental platform including hardware and software for dynamic response of a gun MR recoil damper under impact load was developed. Considering the dynamic behavior of the MR damper under impact load, an inertia factor was introduced into the dynamic model of the recoil part of the gun system. A shock test was done to measure the designed long-stroke MR damper's dynamic performance under impact load. To evaluate the control effect of the MR damper on the gun recoil movement during recoiling, a hardware-in-loop simulation and a test were performed. The testing results showed that the recoil's resistance and stroke of the designed gun MR recoil damper under impact load can be controlled by changing the applied current. The results lay a foundation for the integrated design and engineering application of the gun recoil force and stroke control.

By idealizing a general mapping as a series of local affine ones, we derive approximately transformed material parameters necessary to control solid elastic waves within classical elasticity theory. The transformed elastic moduli are symmetric, and can be used with Navier's equation to manipulate elastic waves. It is shown numerically that the method can provide a powerful tool to control elastic waves in solids in case of high frequency or small material gradient. Potential applications can be anticipated in nondestructive testing, structure impact protection, petroleum exploration and seismology.

View description>>

BACKGROUND: Few studies have evaluated late clinical outcome of no-patch technique in patients with large left ventricular aneurysms. The objectives of this study were to evaluate a no-patch surgical technique to reconstruct the left ventricle in patients with left ventricular aneurysm and to assess early and late clinical outcomes. METHODS: In 1995, we began using a no-patch technique in patients with dyskinetic left ventricular aneurysms. A total of 145 patients underwent left ventricular reconstruction with this technique and were followed up for (59 ± 29) months (range, 1 - 127 months). Risk factors for early mortality were analyzed by bivariate analyses. Cox's proportional hazards model was used to calculate risk factors for all-cause mortality and hospital readmission. Kaplan-Meier methodology was used to analyze late survival. RESULTS: One week after operation, left ventricular end-diastolic diameter had decreased from (61 ± 8) mm to (55 ± 8) mm, and geometry of the left ventricle was restored to a more normal conical shape. Early mortality was 3% and late mortality 11%. Over a 5-year follow-up period, hospital readmission was 28%. One-, 5-, and 10-year survival estimates were 95% (95% confidence interval (CI) 91% - 99%), 86% (95%CI 78% - 94%), and 74% (95%CI 60% - 88%). Readmission-free survival at 1 and 5 years after operation was 87% (95%CI 81% - 93%) and 60% (95%CI 50% - 70%), respectively. CONCLUSION: The no-patch technique for left ventricular reconstruction is an effective and simple procedure that can achieve satisfactory early and late clinical outcomes in patients with left ventricular aneurysms.

Owing to the excessive demand on signal processing and space constraint, a full digital implementation of a large adaptive antenna array at millimeter wave frequencies is very challenging. Targeted at long range high data rate point-topoint link in the 70/80 GHz bands, a novel hybrid adaptive antenna array which consists of analogue subarrays followed by a digital beamformer is presented in this paper to overcome the digital implementation difficulty. Two subarray configurations, the interleaved subarray and the side-by-side subarray, are proposed, and two Doppler resilient adaptive angle-of-arrival estimation and beamforming algorithms, the differential beam tracking (DBT) and the differential beam search (DBS), are developed. Simulation results on the DBT and DBS performance are provided using a 64 element hybrid planar array of four 4 by 4 element subarrays with the two subarray configurations, respectively. Recursive mean square error (MSE) bounds of the developed algorithms are also analyzed and compared with simulated MSEs. © 2006 IEEE.

This paper presents a magneto-thermal model of a high-speed claw pole motor. Core loss is much greater than other losses and is the main source of heat due to the high operating frequency. Therefore it is of crucial importance to be able to calculate the core loss accurately. Three-dimensional finite element analysis is used for core loss calculation and temperature distribution because flux path in claw pole motor is pure three-dimension. The total core loss is computed by separating the alternating and rotational hysteresis, eddy current and anomalous losses in each element. The element's core loss is coupled into elements in thermal analysis by keeping the same mesh structure between magnetic and thermal analysis. Other losses such as air friction loss, rotor loss are included in the model due to high speed. This model is applied to a 2 kW, 20 kr/min three stack claw pole motor with soft magnetic composite core, and the results are compared and discussed finally.

View description>>

Unlike in traditional databases, queries on XML streams are bounded not only by memory but also by real time processing. A novel technique for keyword search over streamed XML fragments is presented, which adopts broadcast model and hole-filler model for XML fragments dissemination, addressing the problem of disordered fragment transmission and considering the quality of searching results due to either keyword mismatch or data absence. Two efficient indexes for candidate elements are developed to further improve the performance: Hierarchical hash table and LCA table. The former indexes structure keywords which act as the structure of result, while the latter indexes the condition keywords which refine the keyword search condition. SLCA computing algorithm, which is triggered by condition keywords, only computes the candidate fragments that involve keywords, thus avoiding redundant operations that will not contribute to the final result. The algorithm produces part of the matched answers continuously without having to wait for the end of the stream. The experiments evaluate the performance of the SLCA algorithm with different types of keywords, different document fragmentation and different keyword frequencies, and compare the SLCA algorithm with other XML keyword matching algorithms. The experiment study shows that the SLCA algorithm performs well on saving processing power and memory space.

The credit crunch and economic crisis have demonstrated the need to properly understand, characterize and assimilate risk in business activities. Failure to do this has resulted in serious consequences to the users involved. So the analysis and management of risk is one of the important pre-requisites to ensure a successful outcome in a business activity in any domain. In this paper we propose an approach by which an interaction initiating user in the domain of e-business ascertains beforehand the level of transactional risk in the successful completion of its business activity and utilizes it to determine on an interaction. The proposed model considers the different sub-categories and characteristics of transactional risk and ascertains in numeric and semantic terms the different levels and severities of its occurrence. It then utilizes the determined analysis of transactional risk to recommend on an informed interaction-based decision to the interaction initiating user. ©2010 CRL Publishing Ltd.

View description>>

Much of the world's essential infrastructure is built along congested coastal belts that are composed of highly compressible and weak soils up to significant depths. Soft alluvial and marine clay deposits have very low bearing capacity and excessive settlement characteristics, with obvious design and maintenance implications on tall structures and large commercial buildings, as well as port and transport infrastructure. Stabilising these soft soils before commencing construction is essential for both long term and short term stability. Pre-construction consolidation of soft soils through the application of a surcharge load alone often takes too long, apart from which, the load required to achieve more than 90% consolidation of these mostly low lying, permeable, and very thick clay deposits can be excessively high over a prolonged period. A system of vertical drains combined with vacuum pressure and surcharge preloading has become an attractive ground improvement alternative in terms of both cost and effectiveness. This technique accelerates consolidation by promoting rapid radial flow which decreases the excess pore-pressure while increasing the effective stress. Over the past 15 years, the Author and his co-workers have developed numerous experimental, analytical and numerical approaches that simulate the mechanics of prefabricated vertical drains (PVDs) and vacuum preloading, including two-dimensional and three-dimensional analyses, and more comprehensive design methods. These recent techniques have been applied to various real life projects in Australia and Southeast Asia. Some of the new design concepts include the role of overlapping smear zones due to P VD-mandrel penetration, pore pressure prediction based on the elliptical cavity expansion theory, and the rise and fall of pore pressure via PVD under cyclic loads. These recent advances enable greater accuracy in the prediction of excess pore water pressure, and lateral and vertical displacement of the stab...

View description>>

An infilled rock joint is likely to be the weakest plane in a rock mass. The most pronounced effect of the presence of infill material is the reduction in 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 joint walls (rock) play no significant role in the overall shear strength. Several models have been proposed to predict the peak shear strength of infilled joints under both constant normal load and constant normal stiffness boundary conditions, taking into account the ratio of infill thickness (t) to the height of the joint wall asperity (a), that is the t/a ratio. Models based on the constant normal stiffness condition provide a much more accurate representation of the infilled joint behaviour in the field, but only a limited number of studies have focused on the more realistic constant normal stiffness stress–strain behaviour. This paper presents a critical review of some of the earlier studies and the most recent advancement of a shear-strength model developed at University of Wollongong, Australia, supplemented with laboratory data for model validation. The effect of different factors on the shear behaviour such as the t/a ratio, infill friction angle, joint wall roughness, joint stiffness and type of infill are presented.

The application of prefabricated vertical drains combined with vacuum and surcharge preloading is considered to be one of the most environmentally friendly ground improvement techniques. The natural atmospheric pressure is used to generate suction via a vacuum pump. In comparison with other ground improvement methods such as deep piling and deep mixing, this method will not only save a substantial cost in road and rail embankment maintenance and construction but will also enhance the speed of construction of coastal highways and rail tracks and their capacity to carry a greater traffic load. Moreover, as drains with vacuum pressure do not involve chemicals, the soil and groundwater chemistry will not change, unlike cement and lime treatment. Vacuum preloading will also reduce the impact on the environment by minimising the greenhouse gas emissions and the need for quarrying natural sand and gravel. The performances of three full-scale test embankments constructed in Thailand, China and Australia are discussed collectively, demonstrating the advantages and environmental benefits of vacuum consolidation in relation to a standard surcharge-only system.

This paper presents the results of the influence of frequency on the permanent deformation and degradation behavior of ballast during cyclic loading. The behavior of ballast under numerous cycles was investigated through a series of large-scale cyclic triaxial tests. The tests were conducted at frequencies ranging from 10-40 Hz, which is equivalent to a train traveling from 73 km/h to 291 km/h over standard gauge tracks in Australia. The results showed that permanent deformation and degradation of ballast increased with the frequency of loading and number of cycles. Much of breakage occurs during the initial cycle; however, there exists a frequency zone of 20 Hz≤f≤30 Hz where cyclic densification takes place without much additional breakage. An empirical relationship among axial strain, frequency and number of cycles has been proposed based on the experimental data. In addition, discrete-element method (DEM) simulations were carried out using PFC2D on an assembly of irregular shaped particles. A novel approach was used to model a two-dimensional (2D) projection of real ballast particles. Clusters of bonded circular particles were used to model a 2D projection of angular ballast particles. Degradation of the bonds within a cluster was considered to represent particle breakage. The results of DEM simulations captured the ballast behavior under cyclic loading in accordance with the experimental observations. Moreover, the evolution of micromechanical parameters such as a distribution of the contact force and bond force developed during cyclic loading was presented to explain the mechanism of particle breakage. It has been revealed that particle breakage is mainly due to the tensile stress developed during cyclic loading and is located mainly in the direction of the movement of ballast particles. © 2010 ASCE.

The interactive proof system model of computation has been studied extensively in computational complexity theory and theoretical cryptography for more than 25 years, and has driven the development of interesting new techniques and insights in those fields. This work considers the quantum interactive proof system model, which is the classical model's natural quantum computational analog. An exact characterization of the expressive power of quantum interactive proof systems is obtained: the collection of computational problems having quantum interactive proof systems consists precisely of those problems solvable with an ordinary classical computer using at most a polynomial amount of memory (or QIP = PSPACE in complexity-theoretic terminology). One striking implication of this characterization is that it implies quantum computing provides no increase in computational power whatsoever over classical computing in the context of interactive proof systems.

The current study investigated the effect of monotonous driving on inter-hemispheric electroencephalography (EEG) coherence. Twenty-four non-professional drivers were recruited to perform a fatigue instigating monotonous driving task while 30 channels of EEG were simultaneously recorded. The EEG recordings were then divided into 5 equal sections over the entire driving period for analysis. Inter-hemispheric coherence was computed from 5 homologous EEG electrode pairs (FP1-FP2, C3-C4, T7-T8, P7-P8, and O1-O2) for delta, theta, alpha and beta frequency bands. Results showed that frontal and occipital inter-hemispheric coherence values were significantly higher than central, parietal, and temporal sites for all four frequency bands (p< 0.0001). In the alpha frequency band, significant difference was found between earlier and later driving sections (p= 0.02). The coherence values in all EEG frequency bands were slightly increased at the end of the driving session, except for FP1-FP2 electrode pair, which showed no significant change in coherence in the beta frequency band at the end of the driving session. © 2010 Elsevier B.V.

The effects of high concentrations of copper (Cu) and zinc (Zn) in a soil treated with biosolids previously spiked with these metals on poplar (Populus deltoidesyunnanensis) were investigated in a pot trial. The total soil metal concentrations in the treatments were 12, 46, 137, and 226mg Cu/kg and 25, 141, 433, and 686mg Zn/kg. Copper accumulation was lower in poplar leaves than Zn and the maximum bioconcentration factor was 0.8 for Cu and 10 for Zn. Copper was not found to be toxic to plants at any level of application or to mycorrhiza up to 137mg/kg, but it was found to be toxic to soil microorganisms at all levels of Cu addition. Copper application increased mycorrhiza colonisation up to 137mg Cu/kg and root dry matter at 226mg Cu/kg, but had no effect on leaf dry matter. Increasing Zn rate decreased all plant and soil parameters. Lower percentages of Cu in the soil exchangeable fraction, and a lower Cu2+ concentrations in soil solution relative to Zn indicated lower bioavailability of Cu. Dehydrogenase activity was reduced by 50% at total solution-phase Cu and Zn concentrations of 0.1 and 27mg/L, respectively, and solid-phase exchangeable Cu and Zn concentrations of 5 and 169mg/kg, respectively. © 2010 CSIRO.

View description>>

In a single degree-of-freedom weakly nonlinear oscillator subjected to periodic external excitation, a small-amplitude excitation may produce a relatively large-amplitude response under primary resonance conditions. Jump and hysteresis phenomena that result from saddle-node bifurcations may occur in the steady-state response of the forced nonlinear oscillator. A simple massâspringâdamper vibration absorber is thus employed to suppress the nonlinear vibrations of the forced nonlinear oscillator for the primary resonance conditions. The values of the spring stiffness and mass of the vibration absorber are significantly lower than their counterpart of the forced nonlinear oscillator. Vibrational energy of the forced nonlinear oscillator is transferred to the attached light mass through linked spring and damper. As a result, the nonlinear vibrations of the forced oscillator are greatly reduced and the vibrations of the absorber are significant. The method of multiple scales is used to obtain the averaged equations that determine the amplitude and phases of the first-order approximate solutions to primary resonance vibrations of the forced nonlinear oscillator. Illustrative examples are given to show the effectiveness of the dynamic vibration absorber for suppressing primary resonance vibrations. The effects of the linked spring and damper and the attached mass on the reduction of nonlinear vibrations are studied with the help of frequency response curves, the attenuation ratio of response amplitude and the desensitisation ratio of the critical amplitude of excitation.

The LU-LC conjecture is an important open problem concerning the structure of entanglement of states described in the stabilizer formalism. It states that two local unitary equivalent stabilizer states are also local Clifford equivalent. If this conjecture were true, the local equivalence of stabilizer states would be extremely easy to characterize. Unfortunately, however, based on the recent progress made by Gross and Van den Nest, we find that the conjecture is false.

This article puts forward a new method in calculating the band structures of low-dimensional semiconductor structures. In this study, the valence band structures of InAs/GaAs quantum ring and lens-shaped quantum dot are calculated with four-band model, in the framework of effective-mass envelope function theory. To determine the Hamiltonian matrix elements, this article develops the numerical Fourier transform method instead of the widely used analytical integral method. The valence band mixing is considered. The hole energy levels change dramatically with the geometrical parameters of the quantum ring and quantum dot. It is demonstrated that numerical Fourier transform method can be adopted in low-dimensional structures with any shape. The results of Fourier transform method are consistent with the ones of analytical integral in literature; and they are helpful for studying and fabricating optoelectronic devices. © 2010 The Journal of China Universities of Posts and Telecommunications.

In this study the hybrid filtration process (combining fibre filter with deep bed dual media filtration) was investigated as pre-treatment to stormwater. This process was investigated in-terms of reduction in turbidity, dissolved organic carbon (DOC), colour, headloss development across the filters, suspended solids removal, organic matter removal, nutrients and heavy matter (such as iron, copper, lead, zinc) removal efficiency. A comparison was made between the hybrid filter with single media (sand) deep bed filter and fibre filter. It was found that the hybrid filtration system successfully removed turbidity (98%), colour (99%), suspended solids (99%), and DOC (55%). The removal efficiency of heavy metal was relatively low as the concentration of heavy metals present in stormwater was low. The removal efficiency of nitrate, nitrite and phosphorous (as orthophosphate) was 27, 35 and 72% respectively. Hybrid filtration processes showed a better reduction of Modified Fouling Index (MFI) value (from 15.500 s/l2 to 9 s/l2) compared with single media sand, anthracite and fibre filter which were 35 s/l2, 13 s/l2and 14 s/l2 respectively when operated at FeCl3 dose of 15 mg/l.

Key components of the miRNA-mediated gene regulation pathway are localized in cytoplasmic processing bodies (P-bodies). Mounting evidence suggests that the presence of microscopic P-bodies are not always required for miRNA-mediated gene regulation. Here we have shown that geldanamycin, a well-characterized HSP90 inhibitor, abolishes P-bodies and significantly reduces Argonaute and GW182 protein levels but does not affect the miRNA level and the efficiency of miRNA-mediated gene repression; however, it significantly impairs siRNA loading and the efficacy of exogenous siRNA. Our data suggests that HSP90 protein chaperones Argonautes before binding RNA and may facilitate efficient loading of small RNA.

BACKGROUND AND PURPOSE µ‐ and δ‐opioid receptors form heteromeric complexes with unique ligand binding and G protein‐coupling profiles linked to G protein α z‐subunit (Gαz) activation. However, the mechanism of action of agonists and their regulation of the µ–δ receptor heteromer are not well understood.EXPERIMENTAL APPROACH Competition radioligand binding, cell surface receptor internalization in intact cells, confocal microscopy and receptor immunofluorescence techniques were employed to study the regulation of the µ–δ receptor heteromer in heterologous cells with and without agonist exposure.KEY RESULTS Gαz enhanced affinity of some agonists at µ–δ receptor heteromers, independent of agonist chemical structure. δ‐Opioid agonists displaced µ‐agonist binding with high affinity from µ–δ heteromers, but not µ receptor homomers, suggestive of δ‐agonists occupying a novel µ‐receptor ligand binding pocket within the heteromers. Also, δ‐agonists induced internalization of µ‐opioid receptors in cells co‐expressing µ‐ and δ‐receptors, but not those expressing µ‐receptors alone, indicative of µ–δ heteromer internalization. This dose‐dependent, Pertussis toxin‐resistant and clathrin‐ and dynamin‐dependent effect required agonist occupancy of both µ‐ and δ‐opioid receptors. In contrast to µ‐receptor homomers, agonist‐induced internalization of µ–δ heteromers persisted following chronic morphine exposure.CONCLUSIONS AND IMPLICATIONS The µ–δ receptor heteromer may contain a novel δ‐agonist‐detected, high‐affinity, µ‐receptor ligand binding pocket and is regulated differently from the µ‐receptor homomer following chronic morphine exposure. Occupancy of both µ‐ and δ‐receptor binding pockets is required for δ‐agonist‐induced endocytosis of µ–δ recepto...

Many software projects spend a significant proportion of their time developing the User Interface (UI), therefore any degree of automation in this area has clear benefits. Such automation is difficult due principally to the diversity of architectures, platforms and development environments. Attempts to automate UI generation to date have contained restrictions which did not accommodate this diversity, leading to a lack of wide industry adoption or standardisation. The authors set out to understand and address these restrictions. We studied the issues of UI generation (especially duplication) in practice, using action research cycles guided by interviews, adoption studies and close collaboration with industry practitioners. In addressing the issues raised in our investigation, we identified five key characteristics any UI generation technique would need before it should expect wide adoption or standardisation. These can be summarised as: inspecting existing, heterogeneous back-end architectures; appreciating different practices in applying inspection results; recognising multiple, and mixtures of, UI widget libraries; supporting multiple, and mixtures of, UI adornments; applying multiple, and mixtures of, UI layouts. Many of these characteristics seem ignored by current approaches. In addition, we discovered an emergent feature of these characteristics that opens the possibility of a previously unattempted goal â namely, retrofitting UI generation to an existing application.

This paper aims to understand the flow structure around submerged dike in the main channel and flood plain of a compound cross section. The study undertaken to develop this understanding was carried out in a laboratory flume using a submerged vane installed at a 90 degree angle to the bank. In order to study the flow structures, the flow velocity was measured using a three-dimensional Acoustic Doppler Velocity meter (micro-ADV) with data collection rate of 50 Hz. These flow velocity measurements were taken at 500 points on a regular grid. As the tests were undertaken with turbulent flow, these conditions were subcritical. Furthermore, all the tests were undertaken using a fixed bed. The results obtained showed that the momentum transfer and the kinetic energy reduced in two directions. Also the energy and momentum coefficients decreased significantly with the installation of the submerged vane inside the main channel. Finally, streamlines were found to deviate from the side walls of channel into the main channel.

The charge of natural organic matter (NOM) is an important parameter for understanding the membrane fouling and NOM removal mechanism with charged membrane. However, there is a lack of technology to make direct measurement of the NOM charge. In this study, we report a novel concept of measuring an apparent charge of the NOM using selectivity coefficient. The apparent charges of three different NOM containing different structures were evaluated to validate this proposed method. The apparent charge of the NOM exhibited a good correlation with specific UV absorbance of the NOM. This apparent charge is therefore a useful indicator for predicting the membrane fouling and NOM removal in membrane filtration technology. © Taylor & Francis Group, LLC.

Dye wastewater flocculation using TiCl4 and FeSO4 coagulants was studied for organic removal and precipitation efficiency. Moreover, TiCl4 was assessed in a pilot-scale flocculation process to investigate organic removal and solution pH effect. A large amount of TiO2 was produced from sludge of Ti-salt flocculation in dye wastewater. This flocculation process simultaneously reduces a large amount of sludge produced from wastewater. The TiO2 nanoparticle was characterized in terms of physical and chemical properties. Results showed that 77.6% of organic matter was removed from dye wastewater when using FeSO4 as coagulant, while TiCl4 degraded 75.9% of organic matter. On the other hand, floc precipitation efficiency was better for TiCl4 if compared with FeSO4. The optimum concentration of TiCl4 for pilot-scale flocculation was found to be equal to 2.1 g/L. DWT (Dye wastewater titania) size was 15-20 nm, mainly doped with carbon atoms and exhibited a dominant anatase structure. DWT was similar to P-25 in decomposing acetaldehyde under UV-irradiation and complete photocatalytic degradation was achieved after 140 min.

Bidens pilosa L (commonly known as cobbler's peg) is an annual broad-leaf weed in tropical and subtropical regions and reportedly needs to be identified and eliminated when farming 31 different crop varieties. This paper presents a multi-modal sensing approach for detecting Bidens leaves within wheat plants. Visual cue-based automatic discrimination of Bidens and wheat leaves is non-trivial owing to the curled-up nature of the wheat leaves. Therefore, spectral responses of Bidens and wheat leaves are first analysed to understand the discriminative spectral bands. Then a multi-modal sensory system consisting of a near infra red (NIR) and a visual camera set-up is proposed. Information retrieved from the sensory set up is then processed to generate a series of cues that are fed into a classification algorithm. Classification results are validated through experimentation. The proposed technique is able to achieve an accuracy of 88—95 per cent even when there is substantial overlapping between Bidens and wheat leaves. Further, it is also shown that the algorithm is robust enough to discriminate some other commonly available plant species.

An online survey was conducted of recent information and communications technology (ICT) graduates from 21 Australian universities. A range of abilities including personal/interpersonal, cognitive, business and technical were examined in relation to importance in the workplace and university preparation of those abilities. In addition, a set of six open-ended text-response questions concerned with the curriculum and other workplace preparation were asked. Quantitative and qualitative analyses revealed a range of responses that were significantly different according to gender. Amongst the significant findings are that females are more concerned than males with interpersonal communication, the development of people-skills and the people side of ICT. Implications for the ICT curriculum are that it should have more than a narrow male-centred technological focus and include the involvement of people and the effects of ICT on society in general. This broad inclusive pedagogical approach would satisfy the needs expressed by all respondents and contribute to increasing the enrolments of both female and male students in ICT.

Although most Australians receive their domestic supply from reticulated mains or town water, there are vast areas with very low population densities and few reticulated supplies. In many of these areas rainwater collected in tanks is the primary source of drinking water. Heavy metals have recently become a concern as their concentration in rain water tanks was found to exceed recommended levels suitable for human consumption. Rainwater storage tanks also accumulate contaminants and sediments that settle to the bottom. Although not widely acknowledged, small amounts of contaminants such as lead found in rain water (used as drinking water) may have a cumulative and poisonous effect on human health over a life time. This is true for certain factors that underlie many of the chronic illnesses that are becoming increasingly common in contemporary society. The paper reports on a study which is part of a project that aims to develop a cost effective in-line filtration system to improve water quality in rainwater tanks. To enable this, the characteristics of rainwater need to be known. One component of this characterization is to observe the effects of the first flush on a rainwater tank. Samples of the roof runoff collected from an urban residential roof located in the Sydney Metropolitan Area in the initial first few millimetres of rain were analysed. The results show that bypassing the first 2mm of rainfall gives water with most water quality parameters compliant with the Australian Drinking Water Guidelines (ADWG) standards. The parameters that did not comply were lead and turbidity, which required bypassing approximately the first 5mm of rainfall to meet ADWG standards. Molecular weight distribution (MWD) analysis showed that the concentration of rainwater organic matter (RWOM) decreased with increasing amount of roof runoff.

Rainwater collected from ten domestic roofs in Sydney and from one in Wollongong, a town south of Sydney, Australia was analysed to determine the water quality and to compare against the Australian Drinking Water Guidelines (ADWG) to determine its suitability as a potable water supply. The pollutants analysed were 13 heavy metals, 8 salts & minerals, pH, ammonia, orthophosphate, conductivity, water hardness, turbidity, total suspended solids, Total dissolved salts & Bicarbonate. The results indicate that the rainwater tested complied to most of the parameters specified in the ADWG. Molecular weight distribution of organic matter from one of the domestic rainwater tanks was analysed in terms of the effects of aging and roof contact. Molecular weight distribution of organic matter in rainwater showed prominent peaks at 37,500 daltons may be due to biopolymers, 850 Da to humic substances, 500 Da to building blocks, 220 Da to low MW acids, and less than 220 Da to amphiphilics. The findings also indicate that the first flush volumes that by-passed the tank can have a significant influence on the water quality in the rainwater tank.

View description>>

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 by using classical converters 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. © 2010 Inderscience Enterprises Ltd.

In submerged membrane system, membrane fouling is linked to the reversible accumulation of macromolecules and solids on the membrane surface and the irreversible sorption of soluble molecules inside the pores. In the first part of the paper, the fouling was analysed at two different aeration rates through the determination of membrane resistance due to (a) sludging (Rsludging), (b) irreversible biofilm (Rbiofilm) and (c) adsorption of organic (Radsorption). These results confirm the importance of aeration for sludge control in the bundle. In the second part of the paper, irreversible foulant obtained at different aeration rates were characterised. Membrane air flow rate limits adsorption of biopolymers onto or into the membrane surface.

In this study, membrane biofouling caused by bacteria that have different characteristics was evaluated using flow field-flow fractionation (FlFFF). Three different bacteria which differed from size and shape (Staphylococcus epidermidis, Escherichia coli, Flavobacterium lutescens) were investigated with GM ultrafiltration (UF, rough with a low negative surface charge and relatively high hydrophobicity) and NE70 nanofiltration (NF, smooth with a high negative surface charge and relatively low hydrophobicity) membranes. The FlFFF retention time of S. epidermidis, E. coli and F. lutescens was highly influenced by the ionic strength of the solution and the surface polarity of the membranes and bacteria. The NF membrane was found to have a higher potential of biofouling than the UF membrane with the bacteria tested in this study. E. coli was the most significant biofoulant among the bacteria tested on both membrane surfaces based on FlFFF retention times compared to other bacteria.

A high rate fibre filter was used as a pre-treatment to seawater reverse osmosis (SWRO) to reduce membrane fouling. Seawater was drawn from Chowder Bay where the Sydney Institute of Marine Science, Australia is located. A lab-scale fibre filter with a height of 1000 mm and a diameter of 30 mm was used in conjunction with in-line coagulation. The effect of operating the fibre filter with different packing densities (105, 115 kg/m3) and filtration velocities (40, 60 m/h) was investigated in terms of silt density index (SDI10), modified fouling index (MFI), pressure drop (ÎP), turbidity and molecular weight distribution (MWD). The use of in-line coagulation improved the performance of fibre filter as measured by the MFI and SDI. Regardless of filtration velocity and packing density the MFI and SDI10 values remained low as did the turbidity until the end of the filtration run. The MWD analysis showed the removal efficiencies of organic materials like biopolymers, fulvic acids, low MW acids for even experiments with the highest filtration velocity (60 m/h) and lowest packing density (105 kg/m3). This pre-treatment has a small foot print as it has the capacity of operating at a very high filtration velocity

State conversion generalizes query complexity to the problem of converting between two input-dependent quantum states by making queries to the input. We characterize the complexity of this problem by introducing a natural information-theoretic norm that extends the Schur product operator norm. The complexity of converting between two systems of states is given by the distance between them, as measured by this norm. In the special case of function evaluation, the norm is closely related to the general adversary bound, a semi-definite program that lower-bounds the number of input queries needed by a quantum algorithm to evaluate a function. We thus obtain that the general adversary bound characterizes the quantum query complexity of any function whatsoever. This generalizes and simplifies the proof of the same result in the case of boolean input and output. Also in the case of function evaluation, we show that our norm satisfies a remarkable composition property, implying that the quantum query complexity of the composition of two functions is at most the product of the query complexities of the functions, up to a constant. Finally, our result implies that discrete and continuous-time query models are equivalent in the bounded-error setting, even for the general state-conversion problem.

A fast design method based on sequential sampling technique is presented for optimizing design engineering electromagnetic devices. Compared with traditional sampling techniques, the proposed technique can reduce the design spaces by the space reduction method. Sequential sampling method has a definite sampling purpose and it can avoid the unnecessary waste of purposeless sampling. Subsequently, the example was investigated. The comparison of the results show that the computation cost of finite element analysis can be saved obviously with this technique. Moreover, it can optimize the design problem directly and improve the fitting accuracy of approximate model. In summary, the proposed method is superior in many respects to direct optimization method and the former sequential optimization method.

We present two new strategies for sequential optimization method (SOM) to deal with the optimization design problems of electromagnetic devices. One is a new space reduction strategy; the other is model selection strategy. Meanwhile, radial basis function (RBF) and compactly supported RBF models are investigated to extend the applied model types for SOM. Thereafter, Monte Carlo method is employed to demonstrate the efficiency and superiority of the new space reduction strategy. Five commonly used approximate models are considered for the discussion of model selection strategy. Furthermore, by two TEAM benchmark examples, we can see that SOM with the proposed new strategies and models can significantly speed the optimization design process, and the efficiency of SOM depends a little on the types of approximate models.

The aim of this study was to examine the current uses of technologies to assist referee decision making processes in professional and Olympic sports, to provide the platform for the facilitation of correct decisions. Through discussion groups and interviews, five major sports in Australia were examined. All participants in the study had all officiated from the grassroots level to the elite level, where at the latter level, had experience in the use of the relevant technologies adopted by their sport. The findings present that, in the majority of the examined sports, differing degrees of technology is being applied to aid the decision making process. When used the technology does provide the mechanism to facilitate in ensuring the correctness of the decision. The success of the introduction of the decision support technology is dependent on its usability, appropriate application and acceptance by the officials and the participants of the match. Via the diligent use and application of appropriate technologies, they can be used as an effective aid to refereeing. Illegal tactics and play were commonplace prior to the introduction of the use of technology to assist the referee. These areas, however, have been dramatically reduced and to a certain extent eliminated. Subsequently these introduced 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.

In practical applications, machine learning algorithms are often needed to learn classifiers that optimize domain specific performance measures. Previously, the research has focused on learning the needed classifier in isolation, yet learning nonlinear classifier for nonlinear and nonsmooth performance measures is still hard. In this paper, rather than learning the needed classifier by optimizing specific performance measure directly, we circumvent this problem by proposing a novel two-step approach called as CAPO, namely to first train nonlinear auxiliary classifiers with existing learning methods, and then to adapt auxiliary classifiers for specific performance measures. In the first step, auxiliary classifiers can be obtained efficiently by taking off-the-shelf learning algorithms. For the second step, we show that the classifier adaptation problem can be reduced to a quadratic program problem, which is similar to linear SVMperf and can be efficiently solved. By exploiting nonlinear auxiliary classifiers, CAPO can generate nonlinear classifier which optimizes a large variety of performance measures including all the performance measure based on the contingency table and AUC, whilst keeping high computational efficiency. Empirical studies show that CAPO is effective and of high computational efficiency, and even it is more efficient than linear SVMperf.

AbstractThis paper presents an iterative, incremental pressure‐stabilized fractional step algorithm for coupled hydro‐mechanical problems with mixed formulations of the displacement–pressure (u–p) model in saturated soil dynamics that allows the use of finite elements with equal low order of interpolation approximation of u and p. In comparison with the original fractional step algorithm, the distinct features of the proposed algorithm lie in its enhanced stability owing to the introduction of both an iteration procedure and a finite increment calculus (FIC) process into the algorithm. The introduction of the iterative procedure makes the velocity term satisfy the momentum conservation equation in an implicit sense and allows much larger time step sizes to be used than those limited in existing explicit and semi‐implicit versions of the algorithm. The introduction of the FIC process removes the dependence of the stability of the proposed algorithm on the time step size, as a result it allows to using the incremental version of the algorithm and evades the minimum time step size requirement presented in the existing versions of the fractional step algorithm that restricts the application of the algorithm to saturated soil dynamics problems with high frequencies.Numerical experiments demonstrate the effectiveness and improved performance of the proposed iterative pressure‐stabilized fractional step algorithm.

View description>>

Magnetorheological fluid (MRF) has received significant attention lately and MRF based devices have been proposed for structural control applications in recent years. The unique characteristics of MR fluid lies in its abilities to reversibly, repeatedly and instantly change from a free flowing liquid to a semi-solid state when exposed to a magnetic field. The electric power required to drive the MR devices can be easily provided by a battery. Possessing such unique properties, MR fluid based devices, such as MR damper, have become promising candidates in the semi-active control for civil structure applications. However, most of the published research has focused on application of MR dampers instead of exploring other type of MR devices. In addition, MR based devices exhibit complex nonlinear hysteresis behaviour and thus making their modelling a challenging task. In this paper, a novel MR fluid based device, namely MR pin joint, is proposed as smart structural members in development of an intelligent civil structure that can suppress unwanted vibrations to ensure safety and serviceability of the structure. After design and fabrication, experiments have been conducted to characterise dynamic behaviours of the new device under different harmonic excitations with various input currents. Test data shows that the MR pin joint possesses a unique behaviour in the moment-angular velocity plot. A hyperbolic hysteresis model is proposed to model such unique behaviour. The investigation presented in the paper explores dynamic performance of MR pin joint. Finally, a parametric model is developed following the investigation on the correlation of coefficients in the proposed model with the loading conditions and applied currents.

AbstractA protein interface can be as “wet” as a protein surface in terms of the number of immobilized water molecules. This important water information has not been explicitly taken by computational methods to model and identify protein binding hot spots, overlooking the water role in forming interface hydrogen bonds and in filing cavities. Hot spot residues are usually clustered at the core of the protein binding interfaces. However, traditional machine learning methods often identify the hot spot residues individually, breaking the cooperativity of the energetic contribution. Our idea in this work is to explore the role of immobilized water and meanwhile to capture two essential properties of hot spots: the compactness in contact and the far distance from bulk solvent. Our model is named geometrically centered region (GCR). The detection of GCRs is based on novel tripartite graphs, and atom burial levels which are a concept more intuitive than SASA. Applying to a data set containing 355 mutations, we achieved an F measure of 0.6414 when ΔΔG ≥ 1.0 kcal/mol was used to define hot spots. This performance is better than Robetta, a benchmark method in the field. We found that all but only one of the GCRs contain water to a certain degree, and most of the outstanding hot spot residues have water‐mediated contacts. If the water is excluded, the burial level values are poorly related to the ΔΔG, and the model loses its performance remarkably. We also presented a definition for the O‐ring of a GCR as the set of immediate neighbors of the residues in the GCR. Comparative analysis between the O‐rings and GCRs reveals that the newly defined O‐ring is indeed energetically less important than the GCR hot spot, confirming a long‐standing hypothesis.

Biomedical signal monitoring systems have rapidly advanced in recent years, propelled by significant advances in electronic and information technologies. Brain-computer interface (BCI) is one of the important research branches and has become a hot topic in the study of neural engineering, rehabilitation, and brain science. Traditionally, most BCI systems use bulky, wired laboratory-oriented sensing equipments to measure brain activity under well-controlled conditions within a confined space. Using bulky sensing equipments not only is uncomfortable and inconvenient for users, but also impedes their ability to perform routine tasks in daily operational environments. Furthermore, owing to large data volumes, signal processing of BCI systems is often performed off-line using high-end personal computers, hindering the applications of BCI in real-world environments. To be practical for routine use by unconstrained, freely-moving users, BCI systems must be noninvasive, nonintrusive, lightweight and capable of online signal processing. This work reviews recent online BCI systems, focusing especially on wearable, wireless and real-time systems.

This paper presents an alternative method in implementing multi-objective optimization of compliant mechanisms in the field of continuum-type topology optimization. The method is designated as "SIMP-PP" and it achieves multi-objective topology optimization by merging what is already a mature topology optimization method-solid isotropic material with penalization (SIMP) with a variation of the robust multi-objective optimization method-physical programming (PP). By taking advantages of both sides, the combination causes minimal variation in computation algorithm and numerical scheme, yet yields improvements in the multi-objective handling capability of topology optimization. The SIMP-PP multi-objective scheme is introduced into the systematic design of compliant mechanisms. The final optimization problem is formulated mathematically using the aggregate objective function which is derived from the original individual design objectives with PP, subjected to the specified constraints. A sequential convex programming method, the method of moving asymptotes (MMA) is then utilized to process the optimization evolvement based on the design sensitivity analysis. The main findings in this study include distinct advantages of the SIMP-PP method in various aspects such as computation efficiency, adaptability in convex and non-convex multi-criteria environment, and flexibility in problem formulation. Observations are made regarding its performance and the effect of multi-objective optimization on the final topologies. In general, the proposed SIMP-PP method is an appealing multi-objective topology optimization scheme suitable for "real world" problems, and it bridges the gap between standard topological design and multi-criteria optimization. The feasibility of the proposed topology optimization method is exhibited by benchmark examples.

This paper presents a new method in designing the core layer of adaptive sandwich structures. The proposed design formulation treats the core layer as a compliant unit cell network while the unit cell network is synthesized by repeatedly linked identical compliant unit cells. Each unit cell is designed to possess shape adaptive functions independently and through the accumulation of the number of cells within the network, the global adaptive functions are accumulated also. Therefore, the network is capable of achieving large scale shape adaptations of complex profile with high fidelity. Topology optimization is used to design the compliant unit cell. Depending on the problem formulation, topology optimization can perform the simultaneous design of both the host material and the actuation material in the defined environment. This research includes a numerical case study to illustrate the technical aspects of this design philosophy. This is followed by the rapid prototyping of two scaled models and experimental validation.

AbstractThe effect of temperature, catalyst system, and the structure of bromine connected groups on the nitroxide radical coupling (NRC) reaction is investigated in details. A series of polymers with different bromine connected groups as poly (tert‐butyl acrylate) (PtBA‐Br), polystyrene (PS‐Br), and poly (methyl methacrylate) (PMMA‐Br) are prepared by atom transfer radical polymerization first, then the bromine‐containing polymers were coupled with 2,2,6,6‐tetramethylpiperidinyl‐1‐oxy‐containing poly(ε‐caprolactone) (PCL‐TEMPO) in different catalyst systems as CuBr/PMDETA, Cu0/PMDETA and CuBr/Cu0/PMDETA in the temperature range from 90 °C to 25 °C. The result shows that the catalyst system of CuBr/Cu0/PMDETA is the best one for NRC reaction, in which the NRC reaction could be conducted in high efficiency in the wide temperature range from room temperature to high temperature. The efficiency of NRC reaction between PtBA‐Br and PCL‐TEMPO is more than 85% in the temperature range from 25 to 75 °C, the efficiency between PS‐Br and PCL‐TEMPO is more than 90% from 25 to 90 °C, and the efficiency between PMMA‐Br and PCL‐TEMPO is more than 90% only at the room temperature. The effect of bromine connected groups on the NRC reaction is discussed. © 2010 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 48: 2991–2999, 2010

OBJECTIVE: To compare the predictive value of glomerular filtration rate (GFR) estimated by the Cockcroft-Gault formula or the modification of diet in renal disease (MDRD) equation and serum creatinine for in-hospital and long-term mortality post coronary artery bypass graft surgery (CABG). METHODS: Clinical data of 5559 consecutive patients undergoing isolated CABG were retrospectively analyzed. The main outcomes were in-hospital mortality and long-term mortality. Estimated GFR was calculated by the Cockcroft-Gault formula and MDRD equation respectively. Receiver-operating characteristic curves and Cox's analysis were used for the comparison. RESULTS: Follow-up was complete in 5485 patients (97.6%). Analysis of receiver-operating characteristic curves showed that GFR estimated by the Cockcroft-Gault formula had a maximal accuracy for predicting in-hospital mortality (area under the curve: 0.755, P < 0.01). Multivariate logistic analysis and the Cox's analysis results indicated estimated GFR < 60 mlxmin(-1)x1.73 m(-2) base on the Cockcroft-Gault formula was an independent risk factor for in-hospital and long-term mortality (hazard ratio 4.51 for in-hospital mortality, P < 0.01; hazard ratio 1.54 for long-term mortality, P < 0.01), both Cockcroft-Gault formula and MDRD equation were superior to serum creatinine for predicting in-hospital and long-term mortality post CABG. CONCLUSION: GFR estimated by the Cockcroft-Gault formula was superior to GFR estimated by the MDRD equation for predicting in-hospital mortality, and estimated GFR was superior to serum creatinine for predicting in-hospital and long-term mortality.

The recently discovered Fe–As superconducting materials which show high potential ability to carry current due to their low anisotropy have attracted a great number of attentions to understand their superconductivity mechanism and explore their applications. This paper presents a method to synthesis SmFeO0.75F0.20As polycrystalline by hot press in detail. The magnetization at different temperatures and applied fields obtained by a superconducting quantum interference device are also discussed. In addition, the local magnetization process is presented by magneto-optical imaging technique at the conditions of zero-field-cooling and field-cooling. It is found that the collective magnetization process of the newly discovered Fe–As superconductors is very similar to that of high-Tc cuprates. For instance, the Fe–As superconductors and high-Tc cuprates have the same magnetization features due to strong pining and intergrain weak link. The global supercurrent is significantly lower than local grain supercurrent due to the weak line between the grains.

Vortices penetration into oxygen-free superconducting compounds FeAs-122 system is of interest in understanding superconductivity. This work studies the vortices motion in Ba(Fe1.8Co0.2)As2 single crystal by means of magneto-optical imaging technique in zero field cooled and field cooled conditions. The captured magneto-optical images and corresponding flux profiles show that, at zero field cooled condition, vortices penetrate into the crystal from the edges as external magnetic field increases. A vortices-free region is observed at the center of sample as applied field is less than full penetration field. In field cooled condition, the introduced vortices leave the sample at the edges as field decreases and polarization of the vortices at the edges are opposite as decreasing field approaches to zero. The pinning strength decreases with increasing temperature. The observed vortex behavior is very similar to that in high Tc superconducting materials with strong pinning strength.

Background: Febrile neutropenia is a common complication in children undergoing chemotherapy for malignancies. A microbial agent is only identified in 15-30% of the fever episodes and corresponds mostly to bacterial findings. Objective: To investigate viral infections as possible etiologic agents in episodes of febrile neutropenia. Study design: Nasopharyngeal aspirates (NPAs) from patients presenting with neutropenic fever at two pediatric oncology wards in Sweden and Australia were analyzed with a conventional virus-diagnostic approach and RT-PCR. Coupled blood samples were analyzed for the detection of CMV, EBV, adenovirus and erythrovirus. Bacterial blood culture was performed routinely. Results: Conventional virus-diagnostic approach coupled to routinely performed bacterial analyzes revealed an infectious agent in 29% compared to 60% when using PCR. By adding PCR, a viral pathogen was detected in 46% of the NPAs and in 4% of the blood samples collected. In half of the patients with bacteremia, respiratory tract viruses were co-detected. Conclusion: Respiratory viruses were frequently detected in NPAs suggesting a significant role of viral infections in children presenting with neutropenic fever. The meaning of these findings needs to be further evaluated but has the potential to individualize infection treatment and to reduce the extensive use of antibiotics in immunocompromised children with neutropenia. © 2009 Elsevier B.V.

This paper presents a new neural network structure and namely node-to-node-link neural network (N-N-LNN) and it is trained by real-coded genetic algorithm (RCGA) with average-bound crossover and wavelet mutation [1]. The N-N-LNN exhibits a node-to-node relationship in the hidden layer and the network parameters are variable. These characteristics make the network adaptive to the changes of the input environment, enabling it to tackle different input sets distributed in a large domain. Each input data set is effectively handled by a corresponding set of network parame-ters. The set of parameters is governed by other nodes. Thanks to these features, the proposed network exhibits better learning and generalization abilities. Industrial application of the proposed network to hand-written graffiti recognition will be presented to illustrate the merits of the network.

In New Zealand and Australia, the BRACElet project has been investigating students' acquisition of programming skills in introductory programming courses. The project has explored students' skills in basic syntax, tracing code, understanding code, and writing code, seeking to establish the relationships between these skills. This ITiCSE working group report presents the most recent step in the BRACElet project, which includes replication of earlier analysis using a far broader pool of naturally occurring data, refinement of the SOLO taxonomy in code-explaining questions, extension of the taxonomy to code-writing questions, extension of some earlier studies on students' 'doodling' while answering exam questions, and exploration of a further theoretical basis for work that until now has been primarily empirical.

View description>>

AbstractWe introduce low‐ASA residue pairs as classification features for distinguishing the different types of protein interactions. A low‐ASA residue pair is defined as two contact residues each from one chain that have a small solvent accessible surface area (ASA). This notion of residue pairs is novel as it first combines residue pairs with the O‐ring theory, an influential proposition stating that the binding hot spots at the interface are often surrounded by a ring of energetically less important residues. As binding hot spots lie in the core of the stability for protein interactions, we believe that low‐ASA residue pairs can sharpen the distinction of protein interactions. The main part of our feature vector is 210‐dimensional, consisting of all possible low‐ASA residue pairs; the value of every feature is determined by a propensity measure. Our classification method is called OringPV, which uses propensity vectors of protein interactions for support vector machine. OringPV is tested on three benchmark datasets for a variety of classification tasks such as the distinction between crystal packing and biological interactions, the distinction between two different types of biological interactions, etc. The evaluation frameworks include within‐dataset, cross‐dataset comparison, and leave‐one‐out cross‐validation. The results show that low‐ASA residue pairs and the propensity vector description of protein interactions are truly strong in the distinction. In particular, many cross‐dataset generalization capability tests have achieved excellent recalls and overall accuracies, much outperforming existing benchmark methods.

The cardinal direction calculus (CDC) proposed by Goyal and Egenhofer is a very expressive qualitative calculus for directional information of extended objects. Early work has shown that consistency checking of complete networks of basic CDC constraints is tractable while reasoning with the CDC in general is NP-hard. This paper shows, however, if allowing some constraints unspecified, then consistency checking of possibly incomplete networks of basic CDC constraints is already intractable. This draws a sharp boundary between the tractable and intractable subclasses of the CDC. The result is achieved by a reduction from the well-known 3-SAT problem.

Direction relations between extended spatial objects are important commonsense knowledge. Recently, Goyal and Egenhofer proposed a relation model, known as the cardinal direction calculus (CDC), for representing direction relations between connected plane regions. The CDC is perhaps the most expressive qualitative calculus for directional information, and has attracted increasing interest from areas such as artificial intelligence, geographical information science, and image retrieval. Given a network of CDC constraints, the consistency problem is deciding if the network is realizable by connected regions in the real plane. This paper provides a cubic algorithm for checking the consistency of complete networks of basic CDC constraints, and proves that reasoning with the CDC is in general an NP-complete problem. For a consistent complete network of basic CDC constraints, our algorithm returns a âcanonicalâ solution in cubic time. This cubic algorithm is also adapted to check the consistency of complete networks of basic cardinal constraints between possibly disconnected regions.

We study optimal perfect distinguishability between a unitary and a general quantum operation. In 2-dimensional case we provide a simple sufficient and necessary condition for sequential perfect distinguishability and an analytical formula of optimal query time. We extend the sequential condition to general d-dimensional case. Meanwhile, we provide an upper bound and a lower bound for optimal sequential query time. In the process a new iterative method is given, the most notable innovation of which is its independence to auxiliary systems or entanglement. Following the idea, we further obtain an upper bound and a lower bound of (entanglement-assisted) q-maximal fidelities between a unitary and a quantum operation. Thus by the recursion in [1] an upper bound and a lower bound for optimal general perfect discrimination are achieved. Finally our lower bound result can be extended to the case of arbitrary two quantum operations.

Particle swarm optimization (PSO) is a population-based evolutionary technique. Advancements in the PSO development over the last decade have made it one of the most promising optimization algorithms for a wide range of complex engineering optimization problems which traditional derivative-based optimization techniques cannot handle. The most attractive features of PSO are its algorithmic simplicity and fast convergence. However, PSO tends to suffer from premature convergence when applied to strongly multi-modal optimization problems. This paper proposes a method of incorporating a real-valued mutation (RVM) operator into the PSO algorithms, aimed at enhancing global search capability. Three variants of PSO algorithms are considered. The resultant hybrid PSO-RVM algorithms are experimentally investigated along with the PSO variants and an existing PSO with Gaussian mutation using six typical benchmark functions. It is interesting to see that the effectiveness of RVM varies for different PSO variants as well as different kinds of functions. It has been found that one of the hybrid algorithms, CBPSO-RVM, which is an integration of the PSO with the constriction factor and inertia weight (CBPSO) and the RVM operator, exhibits significantly better performance in most of the test cases compared to the other algorithms under consideration. Furthermore, this algorithm is superior to most of the existing algorithms used in this study when applied to two practical ED problems with non-smooth cost function considering the multiple fuel type and/or valve-point loading effects.

Australian tertiary education of information technology (IT) has attracted a large number of international students, particularly from Asia. Cultural factors have affected the quality of learning of international students and the teaching approaches adopted by Australian lecturers. Therefore, cross-cultural teaching and learning situations have become an important issue in Australian universities. This study intends to improve the understanding of Asian students' cultural backgrounds, their previous learning approaches and theirperspectives on Australian culture and educational mode, with the objective of helping international students from different cultural backgrounds to overcome the difficulties of cross-cultural study. This study has completed a questionnaire survey of 1026 students, including 292 Information Technology (28.5%) students from five universities in Australia. Among these IT students, there are 100 (34.25%) local students and 192 (65.75%) international students from 39 other countries. The questionnaire contains 55 questions within six question sections and one information section. This paper presents comparison-based data analysis results of this survey on learning methodology and behaviours of Asian students in IT field of Australian universities. It particularly reveals the main difference for students between the universities in their home countries and in Australia, also the difficulties of these students during their study in Australian university through qualitative analysis on open questions of the survey. This paper also reports the research methodology and main findings in cross-culture teaching and learning generated from this study.

Purpose - The purpose of this paper is to develop a hybrid semantic recommendation system to provide personalized government to business (G2B) e-services, in particular, business partner recommendation e-services for Australian small to medium enterprises (SMEs). Design/methodology/approach - The study first proposes a product semantic relevance model. It then develops a hybrid semantic recommendation approach which combines item-based collaborative filtering (CF) similarity and item-based semantic similarity techniques. This hybrid approach is implemented into an intelligent business-partner-locator recommendation-system prototype called BizSeeker. Findings - The hybrid semantic recommendation approach can help overcome the limitations of existing recommendation techniques. The recommendation system prototype, BizSeeker, can recommend relevant business partners to individual business users (e.g. exporters), which therefore will reduce the time, cost and risk of businesses involved in entering local and international markets. Practical implications - The study would be of great value in e-government personalization research. It would facilitate the transformation of the current G2B e-services into a new stage wherein the e-government agencies offer personalized e-services to business users. The study would help government policy decision-makers to increase the adoption of e-government services. Originality/value - Providing personalized e-services by e-government can be seen as an evolution of the intentions-based approach and will be one of the next directions of government e-services. This paper develops a new recommender approach and systems to improve personalization of government e-services.

View description>>

Background: Proteins interacting with each other as a complex play an important role in many molecular processes and functions. Directly detecting protein complexes is still costly, whereas many protein-protein interaction (PPI) maps for model organisms are available owing to the fast development of high-throughput PPI detecting techniques. These binary PPI data provides fundamental and abundant information for inferring new protein complexes. However, PPI data from different experiments do not overlap very much usually. The main reason is that the functions of proteins can activate only on certain environment or stimulus. In a short, PPI is condition-specific. Therefore specifying the conditions on when complexes are present is necessary for a deep understanding of their behaviours. Meanwhile, proteins have various interaction ways and control mechanisms to form different kinds of complexes. Thus the discovery of a certain type of complexes should depend on their own distinct biological or topological characteristics. We do not attempt to find all kinds of complexes by using certain features. Here, we integrate transcription regulation data (TR), gene expression data (GE) and protein-protein interaction data at the systems biology level to discover a special kind of protein complex called conditional co-regulated protein complexes. A conditional co-regulated protein complex has three remarkable features: the coding genes of the member proteins share the same transcription factor (TF), under a certain condition the coding genes express co-ordinately and the member proteins interact mutually as a complex to implement a common biological function.Results: A framework of discovering the conditional co-regulated protein complexes is proposed. Testing on the Yeast data sets under the Cell Cycle, DNA Damage and Dauxic Shift conditions, we identified a total of 29 conditional co-regulated complexes, among which the coding genes in 14 complexes show a strong as...

View description>>

A new multi-objective topology optimization method is proposed in this study for systematic design of multi-phase piezoelectric actuators. The actuator under consideration is composed of a compliant host structure equipped with piezoelectric elements, where the host structure serves as a compliant amplifier to enlarge the small stroke output generated by the actuation force of piezoelectric materials. In the context of optimal design of smart actuators, however, most up-to-date approaches are either to optimize only the host passive structure with pre-determined piezoelectric stacks or to optimize the piezoelectric actuator with pre-known structure, both of which restricts the overall performance of multi-material actuators. To capture the inherent multi-criteria characteristic of compliant actuators, this study proposes a new multi-objective topology optimization formulation to consider both the structural stiffness and mechanical flexibility of the actuation system via the physical programming. A SIMP-based interpolation scheme is applied to describe practical material properties of any points in the orthotropic design domain. The design problem of the actuator is thus transformed to a numerical process of distributing multiple materials iteratively in the design domain until both the host structure and piezoelectric material elements are optimized. Two typical numerical examples are applied to demonstrate the effectiveness of this method in the design of in-plane actuation devices.

Multi-criteria group decision making (MCGDM) aims to support preference-based decision over the available alternatives that are characterized by multiple criteria in a group. To increase the level of overall satisfaction for the final decision across the group and deal with uncertainty in decision process, a fuzzy MCGDM process (FMP) model is established in this study. This FMP model can also aggregate both subjective and objective information under multi-level hierarchies of criteria and evaluators. Based on the FMP model, a fuzzy MCGDM decision support system (called Decider) is developed, which can handle information expressed in linguistic terms, boolean values, as well as numeric values to assess and rank a set of alternatives within a group of decision makers. Real applications indicate that the presented FMP model and the Decider software are able to effectively handle fuzziness in both subjective and objective information and support group decision-making under multi-level criteria with a higher level of satisfaction by decision makers. © 2009 Elsevier B.V.

Team decision-making is a remarkable feature in a complex dynamic decision environment, which can be supported by team situation awareness. In this paper, a team situation awareness measure (TSAM) method using a semantic utility function is proposed. The semantic utility function is used to clarify the semantics of qualitative information expressed in linguistic terms. The individual and team situation awareness are treated as linguistic possibility distributions on the potential decisions in a dynamic decision environment. In the TSAM method, team situation awareness is generated through reasoning and aggregating individual situation awareness based on a multi-level hierarchy mental model of the team. Individual and team mental models are composed of key drivers and significant variables. An illustrative example in telecoms customer churn prediction is given to explain the effectiveness and the main steps of the TSAM method. © 2009 Springer-Verlag.

Detecting logical inconsistency in collected information is a vital function when deploying a knowledge-based warning system to monitor a specific application domain for the reason that logical inconsistency is often hidden from seemingly consistent information and may lead to unexpected results. Existing logical inconsistency detection methods usually focus on information stored in a knowledge base by using a well-defined general purpose knowledge representation approach, and therefore cannot fulfill the demands of a domain-specific situation. This paper first proposes a state-based knowledge representation approach, in which domain-specific knowledge is expressed by combinations of the relevant objects' states. Based on this approach, a method for information logical inconsistency detection (ILID) is developed which can flexibly handle the demands of various domain-specific situations through reducing part of restrictions in existing methods. Finally, two real-case based examples are presented to illustrate the ILID method and its advantages. © 2009 Elsevier B.V. All rights reserved.

A new interference self-cancellation (ISC) method for Single Carrier-FDMA (SC-FDMA) systems is proposed to mitigate the inter-user interference caused by frequency offset or Doppler effect. By transmitting a compensation symbol at the first symbol location in each resource block, the energy leakage can be significantly suppressed. With little bandwidth and power sacrifice, the proposed method can greatly improve the system robustness against frequency offset. Simulation results show that the signal-to-interference ratio (SIR) can be improved by 7 dB on average for the entire system band, and up to 11.7 dB for an individual user. © 2010 IEEE.

The use of Health Information Technology (HIT) within the healthcare setting can be a great resource to contribute to improved patient care. Clinical guidelines are developed to aid in the decision making process of healthcare professionals and contain the leading edge of best patient practice. There is an abundance of evidence presenting the benefits that HIT contain; however, its use is rarely incorporated in today's clinical guidelines. Although, research suggests that the benefits of HIT are enough to integrate their use in clinical guidelines, there are a number of challenges that interfere with its implementation, such as, cultural diversity, interdisciplinary nature, lack of HIT knowledge for workers, evolution of technology, heavy clinical workload and lack of medical background in developers of HIT. The purpose of this research project is to present a literature review to further understand the trends and challenges of implementing HIT use within clinical guidelines. A modelling system, PaJMa is also introduced to visually depict a patient's journey and the methods of documentation. PaJMa can aid in discovering gaps in healthcare documentation and closing those gaps through HIT use within clinical guidelines. Further research revealed that there are models and approaches supporting the process and creation of clinical guidelines but none of these enable the inclusion of what technology will be used to support the implementation of these procedures. The research project concludes with ideas for future research in the area of clinical guideline development and HIT implementation. © of articles is retained by authors.

This paper presents an approach to calculate life-cycle cost analysis of energy efficiency improvement of room air conditioners. The least efficient model from a survey in the market is selected for sample calculation. The method includes the selection of a set of design options that increase efficiency, life cycle cost (LCC) analysis and payback period. LCC is analyzed as a function of seven design options and five variables, namely discount rate, fuel price, appliance lifetime, incremental cost and potential efficiency improvement. The study found that, certain level of efficiency improvement can be achieved, if manufacturers willing to adopt more efficient design options with a little additional investment for the product. Furthermore, the method can be used for other appliances without any major modification.

This paper provides the findings on a project . undertaken to develop a geo-spatial mathematical model relating land-use, road type and air quality. The model shows how spatial elements and issues were quantified to accurately represent the usual and unusual urban environment in the development of residential land-use. The mathematical relationship was based on the optimum distance between residential area and urban transportation network. The spatial data (urban land-use and urban network development) were generated using satellite images, aerial photos and land use maps. Geospatial analyses were performed to find the effect and impact of urban air quality with respect to urban transportation networks. The output of the study would assist the task to reduce negative transport environmental impacts particularism the field of air pollution. It would also be useful in identifying the potential residential area with respect to urban transportation network towards ' achieving sustainable development.

Phytotoxicity due to excessive boron (B) uptake by plants impedes routine agronomic utilisation of coal fly ash. We assessed 11 fly ashes (pH 3.1410.77) having total B content (Bt) of 12136mg/kg, of which 2030% was hot water soluble (Bs) in the acidic ashes (pH 5) and 510% in the alkaline ashes, for their potential to supply B to plants and their risk associated with phytotoxicity. We found the Bs/Bt to be negatively correlated (R2≤0.63, N≤11) with ash pH. We conducted two pot trials in which canola was grown in soils amended with fly ash. In the first trial, an alkaline fly ash (Bt 66mg/kg) was incorporated at 5 rates of up to 625Mg/ha into the top 50mm of 2 acidic soils in 0.30-m-long intact cores, and sown with canola. Boron concentration in leaves at flowering reached the phytotoxic threshold, and both plant growth and seed yield were reduced, only at 625Mg/ha. In the second trial, 4 fly ashes (pH 3.2910.77, Bt 12127mg/kg) were incorporated at 4 rates of up to 108Mg/ha into the top 0.10m of 2 acidic soils in 1.0-m-long intact cores and then sown with canola. Ashes with highest Bt, when applied at 108Mg/ha, increased B concentration in the topsoil only. Of the 2 ashes with the highest B t, only that which produced low soil pH and applied at 108Mg/ha increased B concentration in the shoot, but was still below phytotoxic threshold. The results suggest that B derived from these ashes may not cause phytotoxicity and excessive soil B accumulation if the ashes are applied at modest rates (36Mg/ha) to the topsoil layers. © 2010 CSIRO.

Coal fly ash can be used to ameliorate productivity constraints in agricultural soils, but their efficacy still remains highly variable. To ascertain the capacity of Class F fly ashes to modify pH of acidic soils, and their effects on the yield and uptake of molybdenum (Mo) and selenium (Se) by canola (Brassica napus L.), we applied two acidic and two alkaline Class F ashes at rates equivalent to 0, 12, 36, and 108 Mg/ha to the top layer (0-10 cm) of 100 cm long intact cores of acidic sandy clay and clay loam soils. Only the alkaline ash which had the highest calcium carbonate equivalent (2.43%) increased the pH of the top 10 cm of the sandy clay soil. However, this ash was also highly saline and when applied at ≥36 Mg/ha it increased the electrical conductivity in the top soil layer. Increases in soil pH as a result of alkaline ash addition also elevated concentrations of Se in the plant shoot. The ashes with high concentrations of Mo and Se generally increased uptake of these elements in the plant shoot and/or seed. When these ashes were applied at 108 Mg/ha they increased the concentrations of these elements in the treated topsoil. © 2010 Elsevier Ltd. All rights reserved.

The growing field of Operational Business Intelligence (BI) has resulted in increasing interest in BI-supported Business Processes (BPs), including their management and ongoing improvement. This has led BI practitioners to consider another field–Business Process Management (BPM)–that is closely related to business performance management. However, current approaches to the BPM and operational BI integration have been limited and reduced to the problem of technical integration of BPM and BI systems. This paper argues that by adopting process- thinking in BI, further opportunities for business value creation could be discovered through systematic analysis of the non-technical aspects of BI and BPM integration, including strategy alignment, human-centered knowledge management, and ongoing improvement of BI supported processes. The authors propose a theoretical framework founded in the related research in BPM, BI, and Knowledge Management (KM) fields, describing the ways it has been used to guide ongoing empirical research in diverse case organizations across different industry sectors.

The occurrence and fate of pharmaceuticals in the aquatic environment is recognized as one of the emerging issues in environmental chemistry and as a matter of public concern. Existing data tend to focus on the concentrations of pharmaceuticals in the aqueous phase, with limited studies on their concentrations in particulate phase such as sediments. Furthermore, current water quality monitoring does not differentiate between soluble and colloidal phases in water samples, hindering our understanding of the bioavailability and bioaccumulation of pharmaceuticals in aquatic organisms. In this study, an investigation was conducted into the concentrations and phase association (soluble, colloidal, suspended particulate matter or SPM) of selected pharmaceuticals (propranolol, sulfamethoxazole, meberverine, thioridazine, carbamazepine, tamoxifen, indomethacine, diclofenac, and meclofenamic acid) in river water, effluents from sewage treatment works (STW), and groundwater in the UK

The advancements in the optical technologies that enable researchers to make significant developments in the field of physics and biology have been discussed. One of the researchers, Arthur Ashkin, has demonstrated trapping using two counter-propagating beams and using a single beam that was obtained by propagating a beam vertically and using gravity to balance the radiation pressure force. The optical tweezers system has been introduced that uses a laser source passed through two telescope systems, the first to expand the beam to slightly overfill the back aperture of the microscope objective and the second to make the beam at the microscope conjugate with the beam on a steering mirror. The two multibeam techniques that are widely used includes scanning and holographic. The scanning techniques involve a beam that is scanned very rapidly across the particles of interest. The holographic techniques involve an input Gaussian beam, which has its phase modulated into that of target intensity at the focal plane of the microscope objective.

Health care providers and governments are under pressure to maintain and improve the quality of care to an increasing volume of critical care patients at either end of the life cycle, namely premature and ill term babies together with the elderly. The provision of a service of critical care utilizing real time service-oriented architectures has the potential to enable clinicians to be supported in the care of a greater number patients that are, perhaps more importantly, located elsewhere to their intensive care units. This paper presents a review of recent research in the application of computing and IT to support the service of critical care and determines the trends and challenges for the application of real time service-oriented architectures within the domain. It then presents some case study-based research on the design of a service-oriented architecture-based approach to support two aspects of critical care namely elderly care and neonatal intensive care to provide further context to trends and opportunities. © 2010 Springer-Verlag London Limited.

Cogging torque in permanentmagnet brushless DC (BLDC) motor causes torque and speed ripples, as well as acoustic noise and vibration, especially in low speed and direct drive applications. In this paper, the stator core shape is optimized by using a level set based topology optimization to reduce cogging torque. The level set method can represent the precise boundary shape of structure and also deal with complex topology changes during the optimization process. Different from the conventional rectangular meshes, the level set technique based triangular finite element meshes are presented in this paper to deal with irregular domains. The comparison of cogging torque calculated before and after topology optimization verifies the advantages of the level set topology optimization based on triangular meshes.

In this paper, a multilevel optimization method is proposed for a motor drive system including a surface-mounted permanent magnet synchronous machine (SPMSM), the converter/inverter, and the control schemes. First, the multilevel optimization is described by using the problem matrix which may be used to allocate the design variables on different levels. The parameters in the problem matrix are deduced by using correlation analysis. Second, the architecture and implementation of multilevel genetic algorithm (MLGA) are carried out. As one of the advantages of MLGA, the dynamic adjustment strategy of GA operators is utilized to improve the optimal performance. The algorithm is then applied to a three-level optimization problem in which the optimization of SPMSM design and the control parameters of drive are considered in different levels. Finally, some results and discussions about the application of the proposed algorithm are presented. © 2006 IEEE.

We present the generalized hybrid averaging (GHA) operator. It is a new aggregation operator that generalizes the hybrid averaging (HA) operator by using the generalized mean. Thus, we are able to generalize a wide range of mean operators such as the HA, the hybrid geometric averaging (HGA), the hybrid quadratic averaging (HQA), the generalized ordered weighted averaging (GOWA) operator and the weighted generalized mean (WGM). A key feature in this aggregation operator is that it is able to deal with the weighted average and the ordered weighted averaging (OWA) operator in the same formulation. We further generalize the GHA by using quasi-arithmetic means obtaining the quasi-arithmetic hybrid averaging (Quasi-HA) operator. We conclude the paper with an example of the new approach in a financial decision making problem.

The hybrid averaging (HA) is an aggregation operator that uses the weighted average (WA) and the ordered weighted averaging (OWA) operator in the same formulation. In this paper, we introduce several generalizations of the HA operator by using generalized and quasi-arithmetic means, fuzzy numbers and order inducing variables in the reordering step of the aggregation process. We present the fuzzy generalized hybrid averaging (FGHA) operator, the fuzzy induced generalized hybrid averaging (FIGHA) operator, the Quasi-FHA operator and the Quasi-FIHA operator. The main advantage of these operators is that they generalize a wide range of fuzzy aggregation operators that can be used in a wide range of applications such as decision making problems. For example, we could mention the fuzzy induced hybrid averaging (FIHA), the fuzzy weighted generalized mean (FWGM) and the fuzzy induced generalized OWA (FIGOWA).

We present a new approach that unifies the induced generalized ordered weighted averaging (IGOWA) operator with the weighted average (WA) when the available information is uncertain and can be assessed with interval numbers. We call it the uncertain induced generalized ordered weighted averaging - weighted averaging (UIGOWAWA) operator. The main advantage of this approach is that it unifies the IOWA and the WA taking into account the degree of importance of each case in the formulation and considering that the information is given with interval numbers. We also study different properties of the UIGOWAWA operator and different particular cases. We also analyze the applicability of the new approach and we see that it is possible to develop a wide range of applications because all the previous studies that use the WA can be revised and extended with this new approach. We focus on an application in decision making with the theory of expertons. Thus, we are able to assess group decision making problems in a more complete way.

The investigation focused on girls from schools in the Western suburbs of Melbourne, Australia, home to families with low socio-economic status and students exposed to "educational disadvantage." The article outlines the demographic background of the participating girls, their experiences with ICT, self-efficacy of ICT skills, and their preferences for future studies and careers in ICT. It also analyzes factors that might have influenced the girls' attitudes towards ICT studies and careers, including their ethnic background, exposure to ICT at school and home, and perceptions of ICT. The article concludes with suggestions for future research.

View description>>

Mutation applied indiscriminately across a population has, on average, a detrimental effect on the accumulation of solution alleles within the population and is usually beneficial only when targeted at individuals with few solution alleles. Many common selection techniques can delete individuals with more solution alleles than are easily recovered by mutation. The paper identifies static and dynamic selection thresholds governing accumulation of information in a genetic algorithm (GA). When individuals are ranked by fitness, there exists a dynamic threshold defined by the solution density of surviving individuals and a lower static threshold defined by the solution density of the information source used for mutation. Replacing individuals ranked below the static threshold with randomly generated individuals avoids the need for mutation while maintaining diversity in the population with a consequent improvement in population fitness. By replacing individuals ranked between the thresholds with randomly selected individuals from above the dynamic threshold, population fitness improves dramatically. We model the dynamic behavior of GAs using these thresholds and demonstrate their effectiveness by simulation and benchmark problems.

Kurzfassung Das Prinzip der autonomen Automation wird als Methode der Lean Production zur Kostensenkung durch Vermeidung von Ausschuss und Nacharbeit genutzt. Während in Arbeitssystemen geringer Komplexität integrierte automatische Qualitätsprüfungen bereits erfolgreich zum Einsatz kommen, ist eine Übertragung auf komplexe, verkettete Arbeitssysteme derzeit nicht vollständig umsetzbar. In diesem Beitrag wird am Beispiel eines Walzprozesses ein auf maschinellen Lernverfahren basierender Ansatz zur Realisierung der autonomen Automation in komplexen, verketteten Produktionsprozessen vorgestellt. Hierbei werden verschiedene Herausforderungen, welche durch produktionstechnische Restriktionen entstehen, aufgezeigt und die Notwendigkeit von Weiterentwicklungen bestehender Lernverfahren unter der Zielsetzung der Einbindung in die Produktion dargelegt.

High-order and regularly sampled surface representations are more efficient and compact than general meshes and considerably simplify many geometric modeling and processing algorithms. A number of recent algorithms for conversion of arbitrary meshes to regularly sampled form (typically quadrangulation) aim to align the resulting mesh with feature lines of the geometry. While resulting in a substantial improvement in mesh quality, feature alignment makes it difficult to obtain coarse regular patch partitions of the mesh. In this paper, we propose an approach to constructing patch layouts consisting of small numbers of quadrilateral patches while maintaining good feature alignment. To achieve this, we use quadrilateral T-meshes, for which the intersection of two faces may not be the whole edge or vertex, but a part of an edge. T-meshes offer more flexibility for reduction of the number of patches and vertices in a base domain while maintaining alignment with geometric features. At the same time, T-meshes retain many desirable features of quadrangulations, allowing construction of high-order representations, easy packing of regularly sampled geometric data into textures, as well as supporting different types of discretizations for physical simulation. © 2010 ACM.

The highly strengthened treatment and disposal of excess sludge based on economic and environmental regulation factors is one of the important issues to be dealt with in the activated sludge process. In this study, the reduction and recycling technology of excess sludge were investigated for the aim of achieving a zero emission of excess sludge produced from the activated sludge process using titanium tetrachloride (TiCl4) as a flocculant aid with alkaline-thermal hydrolysis. Alkaline-thermal hydrolysis of excess sludge was obtained 73% and 40% reduction rate at pH 13 (60 8 °C) and pH 11 (60 8 °C), respectively. Flocculation was carried out using a Ti-salt flocculant and the collected sludge was dewatered and incinerated at 600 °C to produce TiO2 nanoparticles. The amount of total suspended solids and volatile suspended solids was significantly decreased with pH increase. The optimal dose of Ti-salt flocculation aid to improve dewatering ability of sludge breakage was 23.95 Ti-mg lâ1. Also, in the batch culture, the supernatant after flocculation and the organic matter released from the lysed sludge were found to be useful as a source of energy for the growth of microorganisms during the aerobic operations period. TiO2 produced from Ti-salt flocculation of excess sludge (TES) was characterized by X-ray diffraction, scanning electron microscopy/energy dispersive X-ray and photocatalytic activity.

A statistical analysis of explosive blast loading field (test) data has revealed a high level of variability of peak reflected pressure, impulse and time of positive phase duration for repeatable tests where variability would be expected to be a minimum. The model error (accuracy) of a widely used predictive blast load model is also assessed. A probabilistic model of blast loading is then developed that considers variability and/or uncertainty of explosive mass, net equivalent quantity of an explosive in terms of TNT mass, stand-off distance, air temperature, air pressure, inherent variability and model error. Two widely used explosives are considered: Tritonal (military) and ANFO (terrorism). This type of statistical and probabilistic analysis is essential for structural reliability analysis of structures subject to explosive blast loading where load variability is an important contributor to damage and safety risks. It was found that the TM5–1300 design values for peak reflected pressure and time of positive phase duration adequately represent median values of the probability distribution of blast loads. The TM5–1300 design values for peak reflected impulse were 40% higher than median values with probabilities of exceedance of only 4% to 23%. This over-estimation of actual blast loads on a structure may lead to conservative design outcomes.

Non-invasive hemodynamic monitoring may facilitate resuscitation in critically ill patients. Validation studies examining a transcutaneous Doppler ultrasound technology, USCOM-1A, using pulmonary artery catheter as the reference standard showed varying results. In this study, we compared non-invasive cardiac index (CI) measurements by USCOM-1A with transthoracic echocardiography (TTE). Methods. This study was a prospective, observational cohort study at a university tertiary-care emergency department, enrolling a convenience sample of adult and pediatric patients. Paired measures of CI, stroke volume index (SVI), aortic outflow tract diameter (OTD), velocity time integral (VTI) were obtained using USCOM-1A and TTE. Pearson's correlation and Bland-Altman analyses were performed. Results. One-hundred and sixteen subjects were enrolled, with obtainable USCOM-1A CI measurements for 99 subjects (55 adults age 50±20 years and 44 children age 11±4 years) in the final analysis. Cardiac, gastrointestinal and infectious illnesses were the most common presenting diagnostic categories. The reference standard TTE measurements of CI, SVI, OTD, and VTI in all subjects were 3.08±1.18 L/min/m2, 37.10±10.91 mL/m2, 1.92±0.36 cm, and 20.36±4.53 cm, respectively. Intra-operator reliability of USCOM-1A CI measurements showed a correlation coefficient of r = 0.79, with 11±22% difference between repeated measures. The bias and limits of agreement of USCOM-1A compared to TTE CI were 0.58 (-1.48 to 2.63) L/min/m2. The percent difference in CI measurements with USCOM-1A was 31±28% relative to TTE measurements. Conclusions. The USCOM-1A hemodynamic monitoring technology showed poor correlation and agreement to standard transthoracic echocardiography measures of cardiac function. The utility of USCOM-1A in the management of critically ill patients remains to be determined. © Springer 2010.

Background. Lactate clearance, a surrogate for the magnitude and duration of global tissue hypoxia, is used diagnostically, therapeutically and prognostically. This study examined the association of early lactate clearance with selected inflammatory, coagulation, apoptosis response biomarkers and organ dysfunction scores in severe sepsis and septic shock. Methods. Measurements of serum arterial lactate, biomarkers (interleukin-1 receptor antagonist, interleukin-6, interleukin-8, interleukin-10, tumor necrosis factor-alpha, intercellular adhesion molecule-1, high mobility group box-1, D-Dimer and caspase-3), and organ dysfunction scores (Acute Physiology and Chronic Health Evaluation II, Simplified Acute Physiology Score II, Multiple Organ Dysfunction Score, and Sequential Organ Failure Assessment) were obtained in conjunction with a prospective, randomized study examining early goal-directed therapy in severe sepsis and septic shock patients presenting to the emergency department (ED). Lactate clearance was defined as the percent change in lactate levels after six hours from a baseline measurement in the ED. Results. Two-hundred and twenty patients, age 65.0 17.1 years, were examined, with an overall lactate clearance of 35.5 43.1% and in-hospital mortality rate of 35.0%. Patients were divided into four quartiles of lactate clearance, -24.3 42.3, 30.1 7.5, 53.4 6.6, and 75.1 7.1%, respectively (p < 0.01). The mean levels of all biomarkers and organ dysfunction scores over 72 hours were significantly lower with higher lactate clearance quartiles (p < 0.01). There was a significant decreased in-hospital, 28-day, and 60-day mortality in the higher lactate clearance quartiles (p < 0.01). Conclusions. Early lactate clearance as a surrogate for the resolution of global tissue hypoxia is significantly associated with decreased levels of biomarkers, improvement in organ dysfunction and outcome in severe sepsis and septic shock. © 2010 Nguyen et al; licensee BioMed Centra...

Background: Evidence-based therapies for severe sepsis include early antibiotics, early goal-directed therapy, corticosteroids, recombinant human activated protein C, glucose control, and lung protective strategies. Objective: The objective of this study was to analyze methods, challenges, and outcomes observed by hospitals that implemented a hospital-wide sepsis management protocol incorporating evidence-based therapies. Methods: In a cross-sectional multi-center telephone survey over a 4-month period, clinicians (participants) responsible for developing a hospital sepsis protocol were questioned regarding its development and outcomes. Results: Participants completing surveys represented 40 hospitals (20 academic and 20 community). Twenty-seven percent of protocol champions were Emergency physicians or nurses. Sixty-three percent reported protocol development time of 6-12 months. Eighty-eight percent of participants reported protocol initiation in the Emergency Department. Three participants reported hiring a nurse educator to implement the protocol. Ninety-five percent of participants measure lactate as part of patient screening. Protocol therapies reported included early antibiotics (98%), early goal directed-therapy (EGDT) (98%), corticosteroids (80%), and activated protein C (73%). Contributions to success included having a protocol champion (85%) and sepsis education program (65%). Twenty-one participants had recorded patient-level data, totaling 2319 protocol patients, compared to 1719 non-protocol patients, with in-hospital mortality of 23% and 44%, respectively. Conclusions: Implementation of a sepsis management protocol incorporating evidence-based therapies can be accomplished in both academic and community hospitals, with minimal additional staffing. The presence of a protocol champion and education program is crucial to success, and may result in improved patient outcome. © 2010 Elsevier Inc. All rights reserved.

Background and purpose: We present the early experience in thrombolysis in three major centers of Ho Chi Minh city, namely 115 People Hospital, Gia Dinh Hospital, and An Binh Hospital. Methods: A prospective study of consecutive patients treated with intravenous tPA with a treatment protocol similar to that of the National Institute of Neurological Disorders and Stroke (NINDS) trial. National Institutes of Health Stroke Scale (NIHSS) scores on admission and Modified Rankin Scale (MRS) scores at 3 months were measured for all patients. Intracranial and systemic hemorrhagic complications were recorded. Result: A total of 121 of 6171 (2%) patients with acute IS received thrombolysis over 3 years. Mean age was 57 years (range 18-78) and initial median NIHSS score was 12 (range 5-23). The mean delay between symptom onset and treatment was 143 min (range 50-210). Seventy-three (60.3%) patients received the standard dose with the remaining 48 patients (36.9%) treated with a lower dose, a mean calculated dose of 0.62 mg/kg (range, 0.6-0.86 mg/kg). Over half (56.3%) of the patients receiving low dose achieved functional independence (mRS score 0-1) at 3 months compared with 34.2% in the standard-dose group (P = 0.01). The 3-month mortality rate was also higher in the standard-dose group (2.1% vs. 12.5% with standard-dose tPA; P = 0.04). Symptomatic intracranial hemorrhage was noted in four patients of standard-dose group and one patient of low-dose group (P = 0.36). Conclusion: Intravenous thrombolysis, particularly in a lower dose, is safe and feasible in the treatment of acute IS in our selected Vietnamese population.

In this study, a new combined inorganic-organic flocculant (CIOF) of FeCl3 and membrane performance enhancer (MPE50) was prepared and added to an aerated submerged membrane bioreactor (SMBR). The effects of CIOF on the performance of an aerated submerged membrane bioreactor (SMBR) were evaluated. The results indicated that the SMBR with CIOF addition could remove almost 100% total phosphate while eliminating over 90% ammonia (NH 4-N) and dissolved organic carbon (DOC) during an 80-day of operation. The respiration tests revealed that the specific oxygen uptake rate (SOUR) was stable around 1.5-2.0 mg O2/gMLVSS h. The sludge volume index (SVI) of less than 100 mL/g during the operation showed the importance of CIOF on the improvement of settling properties of the sludge. Soluble carbohydrate concentration was also well correlated with DOC of the supernatant. CIOF was successful in the reduction of fouling of membrane as the membrane was only chemically cleaned after 53 days of operation. © 2010 Elsevier B.V. All rights reserved.

The effects of polyurethane sponge size and type on the performance of an up-flow sponge bioreactor were studied using different sponge cube sizes (1 × 1 × 1 cm, 2 × 2 × 2 cm and 3 × 3 × 3 cm) and types of sponge (S28-30/45R, S28-30/60R, S28-30/80R and S28-30/90R). The reactors were operated under anaerobic conditions in an early stage and an aerobic condition in a latter stage. The results indicate that there was no significant difference in the organic and nutrient removal rates between sponge types. The medium size sponge (2 × 2 × 2 cm) had the best performance in terms of both biomass growth and pollutants removal. Under anaerobic condition, the COD, TN and TP removal efficiencies were up to 70%, 45% and 55%, respectively, and significantly improved under aerobic conditions (e.g. >90% TOC, 95% COD, 65% TN and 90% TP). The external biomass grew faster under anaerobic conditions while internal biomass was dominant under aerobic condition. © 2009 Elsevier Ltd.

Millions of people worldwide are at risk from the presence of arsenic in groundwater. In this study, adsorption equilibrium and long term experiments were carried out to evaluate the performance of iron oxide coated sponge (IOCSp) in arsenic removal. It was found that maximum adsorption capacity of IOCSp for As(III) and As(V) calculated by Sips isotherm was 4.2 and 4.6. mg/g of IOCSp, respectively. A filter packed with small amount of 25. g IOCSp maintained a consistent arsenic removal efficiency of 95% from synthetic solution containing arsenic concentration of as high as 1000. μg/L. This produced a throughput volume of 153 and 178. L of water containing As(III) and As(V), respectively before any need for regeneration or disposal of IOCSp. IOCSp could be regenerated by washing it with NaOH solution. The dynamic (column) adsorption kinetics were successfully predicted by the Thomas and Nikolaidis modified models. © 2010 Elsevier B.V.

AbstractA mathematical model is established to simulate the formation of extracellular polymeric substances (EPS), soluble microbial products (SMP), and internal storage products (XSTO) in aerobic granular sludge. The sensitivity of these microbial products concentrations toward the key model parameters is analyzed. Independent experiments are conducted to find required parameter values and to test its predictive ability. The model is evaluated by using one‐cycle operating experimental results of a lab‐scale aerobic granule‐based sequencing batch reactor (SBR) and batch experimental results. Results show that the model is able to describe the microbial product dynamics in aerobic granules and provide further insights into a granule‐based SBR. The effect of the initial substrate and biomass concentrations on the formation of microbial products in aerobic granular sludge can therefore be analyzed by model simulation. A higher substrate concentration results in a greater concentration of EPS, SMP, and XSTO. An accumulation of biomass in the bioreactor leads to an increased production rate of EPS, SMP, and XSTO. © 2009 American Institute of Chemical Engineers AIChE J, 2010

AbstractPredation by protozoa plays an important role in activated sludge. In this work, the kinetics for protozoan predation of active bacteria (XH), extracellular polymeric substances (EPS), and intracellular storage products (XSTO) are added into a previously expanded unified model that describes the dynamics of EPS, XSTO, and soluble microbial products (SMP). The new biomass growth–decay–predation model describes the biomass fractions, soluble organic components, and oxygen‐uptake rates considering EPS, XSTO, and predators during dynamic operating conditions in activated sludge. Model calibration using batch experimental data provides the new parameter values for predation processes and insights into mechanisms involving predators. The calibrated value of the maximum specific growth rate for the predators is much slower than for the bacteria, confirming that predators are relatively slow growers. However, the predators and bacteria have similar decay rates and dissolved oxygen affinities. Model testing with results independent of the calibration data shows two things. First, the model and calibrated parameters accurately simulate the independent results when predators are present. Second, eliminating predation by high salinity significantly lowers the OUR, and this is captured by the model. Biotechnol. Bioeng. 2010;105: 1021–1030. © 2009 Wiley Periodicals, Inc.

AbstractIn wastewater treatment plants (WWTPs) the production of nitrite as an intermediate in the biological nutrient removal (BNR) process has been widely observed, but not been taken into account by most of the conventional activated sludge models yet. This work aims to develop a mechanistic mathematical model to evaluate the BNR process after resolving such a problem. A mathematical model is developed based on the Activated Sludge Model No.3 (ASM3) and the EAWAG Bio‐P model with an incorporation of the two‐step nitrification–denitrification, the anoxic P uptake, and the associated two‐step denitrification by phosphorus accumulating organisms. The database used for simulations originates from a full‐scale BNR municipal wastewater treatment plant. The influent wastewater composition is characterized using batch tests. Model predictions are compared with the measured concentrations of chemical oxygen demand (COD), NH‐N, NO‐N, NO‐N, PO‐P, and mixed liquid volatile suspended solids. Simulation results indicate that the calibrated model is capable of predicting the microbial growth, COD removal, nitrification and denitrification, as well as aerobic and anoxic P removal. Thus, this model can be used to evaluate and simulate full‐scale BNR activated sludge...

ABSTRACT Anaerobic ammonium oxidation (anammox) is a promising new process to treat high-strength nitrogenous wastewater. Due to the low growth rate of anaerobic ammonium-oxidizing bacteria, efficient biomass retention is essential for reactor operation. Therefore, we studied the settling ability and community composition of the anaerobic ammonium-oxidizing granules, which were cultivated in an upflow anaerobic sludge blanket (UASB) reactor seeded with aerobic granules. With this seed, the start-up period was less than 160 days at a NH 4 + -N removal efficiency of 94% and a loading rate of 0.064 kg N per kg volatile suspended solids per day. The formed granules were bright red and had a high settling velocity (41 to 79 m h −1 ). Cells and extracellular polymeric substances were evenly distributed over the anaerobic ammonium-oxidizing granules. The high percentage of anaerobic ammonium-oxidizing bacteria in the granules could be visualized by fluorescent in situ hybridization and electron microscopy. The copy numbers of 16S rRNA genes of anaerobic ammonium-oxidizing bacteria in the granules were determined to be 4.6 × 10 8 copies ml −1 . The results of this study could be used for a better design, shorter start-up time, and more stable operation of anammox systems for the treatment of nitrogen-rich wastewaters.

Directed Cooperation in Multihop Wireless Sensors NetworkThis paper proposes a relational abstraction for Wireless Sensors Network where node can identify its neighbors around it. Because of limited radio link range only some of nodes have a direct contact with the base station and transmission is carried out in a multihop way so information is send from one node to another towards the BS. We propose a relation π that represents cooperation between nodes and takes advantages of topological properties of the network. Based on the hop-distance from the BS any nodekcan determine a setN<(k) that consists of nodes to which/kshould send messages in order to retain a data-flow direction towards the BS.

In this study, titanium (Ti), ferric (Fe) and aluminum (Al) salt flocculants were compared for their efficiency in treating wastewater collected from Sydney Olympic Park wastewater treatment plant by following the jar test procedure. Produced sludge from Ti-salt flocculation was dried and titanium dioxide (TiO2) nanoparticles were generated after the incineration of sludge produced from the Ti-salt flocculation of wastewater. Later on, titanate nanotubes were synthesized after TiO2 nanoparticles were hydrothermally treated with 10 N NaOH solution at 130 °C for 24 h. Titanate nanotubes were either acid or deionised water-washed, while thiourea-doping was employed to produce visible light-responsive nanotubes. Wastewater flocculation using Ti-salt was found to be as efficient as Fe and Al flocculation in terms of turbidity and DOC removal. XRD results showed that the anatase structure was predominant for TiO2 nanoparticles, while thiourea-doped titanate nanotubes only indicated anatase structure with an increased crystallinity after being crystallized at 600 °C. The photocatalytic activity of all photocatalysts was evaluated using the photooxidation of acetaldehyde. Thiourea-doped nanotubes showed a greater photocatalytic activity than as-prepared TiO2 nanoparticles, deionised water-washed, acid-washed titanate nanotubes and P25 under UV and visible light irradiation.

BACKGROUND AND AIM OF THE STUDY: The study aim was to investigate the mid-term risk factors for neo-aortic regurgitation in patients with transposition of the great arteries (TGA) and Taussig-Bing malformation after the arterial switch operation (ASO). METHODS: Between February 2001 and December 2007, a total of 202 patients with TGA or Taussig-Bing malformation underwent the ASO at the authors' institution. Subsequently, 185 surviving patients (140 males, 45 females; mean age 14 +/- 28 months) were followed up in the out-patient department, using echocardiography. A multiple logistic regression analysis was performed to identify the risk factors for postoperative neo-aortic regurgitation. RESULTS: The mean period of follow up was 35 +/- 22 months (range: 3 to 88 months). Postoperative neo-aortic regurgitation was present in 19 patients; this was mild in 16 cases (9%) and moderate in three (2%). During the follow up, freedom from aortic regurgitation was 90%; the overall rates of freedom from aortic regurgitation at one, three, and five years were 95%, 89%, and 83%, respectively. The mid-term risk factors for neo-aortic regurgitation were ventricular septal defect (VSD) (p = 0.02), operative age >6 months (p = 0.01), and a postoperative neo-aortic valve Z-score >1 (p <0.01). CONCLUSION: The ASO showed an acceptable midterm function of the aortic valve. The risk factors for postoperative neo-aortic regurgitation included VSD, operative age >6 months, and a postoperative neo-aortic valve Z-score >1.

The ACs (R-1/2 and R-1/4) having two different textual and chemical properties are prepared from corn-based biomass precursor and evaluated together with a wood-based activated carbon (WAC) at room temperature using a gas chromatograph. The results obtained from the correlation studies indicate that the pore size distribution (below 8A Ë ) and the relatively lower energetic heterogeneity of ACs on acetaldehyde adsorption are considerable factors rather than that of a specific surface area and surface chemistry. The adsorption equilibrium of ACs is well correlated with the Sips equation. The pseudo second-order equation was better in describing the ACsâ adsorption kinetic of acetaldehyde.

As part of continuing investigation into noise barrier optimisation, a research and development study to conduct insitu empirical testing of several full size prototype barrier designs was funded by the NSW State Government. Of particular interest to this study was a design known as a random edge profile barrier. Literature research had found that there was a body of evidence indicating that a barrier with an edge irregularity can cause a substantial degradation of the diffracted signal. It is generally accepted that an increase in insertion loss occurs because the jagged edge causes a reduction in coherence of the diffracted signal being transmitted to the shadow zone as compared to a conventional straight edge barrier [1-3]. It has been suggested that the mechanism for this is that the jagged geometry on the top of a barrier alters the sound pressure level in the shadow zone by causing the region of the barrier nearest the receiver to admit multiple paths with variable phase [4]. The direct waves from the diffracting edges of the barrier and waves subsequently reflected from the ground plane are superimposed at the receiver causing constructive or destructive interference at the receiver. The present study followed a methodology that included construction of an 80m long by 2.4m high barrier that served as the base for an additional conventional top as well as a random profile and T-top novel cap. Empirical data collected showed that for the receiver locations investigated, a random edge barrier will out-perform a conventional barrier of the same nominal height for most frequencies associated with broadband tyre/road noise. A T-top barrier was found to perform better than a conventional barrier of similar height for most frequencies whilst a conventional barrier offered the most practical solution for attenuation of low frequency noise.

The barriers were constructed of a 28mm timber laminate exclusively for use as a noise barrier. This laminate was provided in sheets that were 2.4 x 1.2 meters and were fixed between galvanized H-beams. Three precision microphones were set up at various locations in front of and behind each barrier configuration. Designated A, B, and C these microphones captured traffic noise data simultaneously at various combinations of the measurement points (MPs). Synchronized video footage of the roadway was also collected to allow identification and characterization where necessary of the traffic noise sources. The random edge barrier with a nominal height of 3.0m was found to approximate the performance of a 3.0m conventional barrier at microphone locations (MP2 and MP4) close to the barrier.

For nonlinear state space model involving random variables with arbitrary probability distributions, the state estimation given a sequence of observations is based on an appropriate criterion such as the minimum mean square error (MMSE). This leads to linear approximation in the state space of the extended Kalman filter (EKF) and the unscented Kalman filter (UKF), which work reasonably well only for mildly nonlinear systems. We propose a Bayesian filtering technique based on the MMSE criterion in the framework of the virtual linear fractional transformation (LFT) model, which is characterized by a linear part and a simple nonlinear structure in the feedback loop. LFT is an exact representation for any differentiable nonlinear mapping, so the virtual LFT model is amenable to a wide range of nonlinear systems. Simulation results demonstrate that the proposed filtering technique gives better approximation and tracking performance than standard methods like the UKF. Furthermore, for highly nonlinear systems where UKF diverges, the LFT model estimates the conditional mean with reasonable accuracy. Copyright © 2010 IEEE.

Long duration driving is a significant cause of fatigue related accidents of cars, airplanes, trains and other means of transport. This paper presents a design of a detection system which can be used to detect fatigue in drivers. The system is based on computer vision with main focus on eye blink rate. We propose an algorithm for eye detection that is conducted through a process of extracting the face image from the video image followed by evaluating the eye region and then eventually detecting the iris of the eye using the binary image. The advantage of this system is that the algorithm works without any constraint of the background as the face is detected using a skin segmentation technique. The detection performance of this system was tested using video images which were recorded under laboratory conditions. The applicability of the system is discussed in light of fatigue detection for drivers.

PVC/Aliquat 336 Polymer Inclusion Membranes (PIMs) synthesised in this study showed excellent extraction selectivity of Cd2+ over Cu 2+. This could be explained by examining the extraction mechanisms of metal cations involving Aliquat 336 and the speciation of such metals in a chloride matrix, which was used in the extraction experiments. There was a good correlation between the content of Aliquat 336 in the membrane and the extraction rate. In addition, results reported here also confirm that variation Molecular Weight (MW) of the base polymer PVC did not exert any discernible influence on the extraction performance of the membranes. © 2010 Inderscience Enterprises Ltd.

Kurzfassung Zur Reduzierung von Planungszeit und -kosten sowie zur Steigerung der Produktivität müssen alle Aufgaben der Produktentstehung optimal aufeinander abgestimmt sein. Die erforderliche enge Zusammenarbeit unterschiedlicher Fachdomänen wird jedoch auf Grund zahlreicher Schnittstellenprobleme vielfach nicht erreicht. Die Ursachen hierfür liegen sowohl in organisatorischen als auch in technischen Defiziten, die eine mit allen Partnern abgestimmte Planung verhindern. Gerade die Vernetzung von digitalen und nicht-digitalen Methoden ist bislang in den Unternehmen nur unzureichend realisiert. Um die Durchgängigkeit von Planungsprozessen und die Abstimmung von Planungsteilbereichen zu erhöhen, wird eine domänenübergreifende Referenzplanungssystematik entwickelt.

This paper addresses the robust stabilization and H infinity control problem for a class of linear polytopic systems with continuously distributed delays. The control objective is to design a robust H infinity controller that satisfies some exponential stability constraints on the closed-loop poles. Using improved parameter-dependent Lyapunov Krasovskii functionals, new delay-dependent conditions for the robust H infinity control are established in terms of linear matrix inequalities.

Bhutan lacks the solid waste data which are essential parameters for planning and scheduling of municipal solid waste management (MSWM) systems. The first ever large-scale research survey on solid waste generation and characterization in the urban areas of Bhutan was conducted between November 2007 and January 2008 using the method of waste sampling at source. The MSW generation rates in the urban centres were 0.53 kg capita-1 day - 1, which consists predominantly of organic waste materials of up to 58% indicating a great opportunity for composting. Domestic waste from the households contributed the maximum (47%) component of the total MSW generated from the urban centres followed by wastes from the commercial establishments. Attempt to study the correlation between household monthly income and the waste per capita generation rates did not yield any conclusive result. © The Author(s), 2010.

The aim of this study is to evaluate the susceptibility of landslides at Klang valley area, Malaysia, using a Geographic Information System (GIS) and remote sensing. 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. A data derived model (frequency ratio) and a knowledge-derived model (fuzzy operator) were combined for landslide susceptibility analysis. The nine factors that influence landslide occurrence were extracted from the database and the frequency ratio coefficient for each factor was computed. Using the factors and the identified landslide, the fuzzy membership values were calculated. Then fuzzy algebraic operators were applied to the fuzzy membership values for landslide susceptibility mapping. Finally, the produced map was verified by comparing with existing landslide locations for calculating prediction accuracy. Among the fuzzy operators, in the case in which the gamma operator (λ = 0.8) showed the best accuracy (91%) while the case in which the fuzzy algebraic product was applied showed the worst accuracy (79%).

Bone provides an important source of forensic evidence. The storage conditions of bone have been recognised as a factor in maintaining the integrity of such evidence. Thermogravimetric analysis (TG) has been employed to examine the effects of storage environments and preparation methods on the structural properties of pig bones. A comparison of oven and freeze drying has been made to study the effect of storage conditions. A comparison has also been made of ground bone specimens with cut specimens. Freeze-dried hand ground specimens provided the most consistent results and, thus, this is the recommended method of preparation of bone specimens for TG analysis.

AbstractA new compact configuration of a printed CPW‐fed semicircular slot antenna with a CPW‐to‐CPW step transition is presented. Its bandwidth is enhanced for ultra‐wideband (UWB) operation by combining linear and stepped CPW‐to‐CPW transitions along the feed line. Its measured 10 dB return loss bandwidth is 3.1–13.8 GHz (126%). This, together with its nearly constant measured gain of 3.5 dBi ± 1 dB from 3 to 10 GHz, makes it suitable for UWB applications.

AbstractA constant‐gain printed circular monopole antenna (PCMA) is presented that operates from 4 to 12 GHz. The gain of the PCMA is enhanced with the use of surface‐wave excited, proximity‐coupled (SW‐PC), conductor‐backed, twin‐slot radiators. A significant improvement in 2 and 3 dB peak gain bandwidth in the XY plane (θ = 90°) is achieved, and the peak measured gain of the antenna is nearly constant (5.5 dBi ± 1.5 dB) from 3 to 10 GHz. It has a very broad radiation pattern in the azimuth plane and a typical figure of eight pattern in the elevation plane. The antenna is also compact, robust, and easy to fabricate. © 2010 Wiley Periodicals, Inc.

Neurotrophins are growth factors that are important in neuronal development and survival as well as synapse formation and plasticity. Many of the effects of neurotrophins are mediated by changes in protein expression as a result of altered transcription or translation. To determine whether neurotrophins regulate the production of microRNAs (miRNAs), small RNA species that modulate protein translation or mRNA stability, we used deep sequencing to identify BDNF (brain-derived neurotrophic factor)-induced miRNAs in cultured primary cortical mouse neurons. This revealed that the miR-212/132 cluster contained the miRNAs most responsive to BDNF treatment. This cluster was found to produce four miRNAs: miR-132, miR-132*, miR-212 and miR-212*. Using specific inhibitors, mouse models and promoter analysis we have shown that the regulation of the transcription of the miR-212/132 miRNA cluster and the miRNAs derived from it are regulated by the ERK1/2 (extracellular-signal-regulated kinase 1/2) pathway, via bothMSK (mitogen and stress-activated kinase)-dependent and -independent mechanisms. © The Authors.

Conventional and modified membrane bioreactors (MBRs) are increasingly used in small-scale wastewater treatment. However, their widespread applications are hindered by their relatively high cost and operational complexity. In this study, we investigate a new concept of wastewater treatment using a nonwoven fabric filter bag (NFFB) as the membrane bioreactor. Activated sludge is charged in the nonwoven fabric filter bag and membrane filtration via the fabric is achieved under gravity flow without a suction pump. This study found that the biofilm layer formed inside the NFFB achieved 10 mg/L of suspended solids in the permeate within 20 min of initial operation. The dynamic biofilter layer showed good filterability and the specific membrane resistance consisted of 0.3â1.9 Ã 1012 m/kg. Due to the low F/M ratio (0.04â0.10 kg BOD5/m3/d) and the resultant low sludge yield, the reactor was operated without forming excess sludge. Although the reactor provided aerobic conditions, denitrification occurred in the biofilm layer to recover the alkalinity, thereby eliminating the need to supplement the alkalinity. This study indicates that the NFFB system provides a high potential of effective wastewater treatment with simple operation at reduced cost, and hence offer an attractive solution for widespread use in rural and sparsely populated areas.

Everyone, and most everything, needs a clock, and computers are no exception. Clocks tend to drift off if left to themselves, however, so it is necessary to bring them to heel periodically through synchronizing to some other reference clock of higher accuracy. An inexpensive and convenient way to do this is over a computer network.

Little information is available on the interactive effects of soluble and less-soluble phosphorus (P) fertilisers and weed control on growth and P nutrition of second-rotation Pinus radiata plantations. A study was initiated on three-year-old secondrotation P. radiata and to determine the relationship between needle P concentrations and soil P forms in an Orthic Pumice soil two years after application. Four rates of P (0, 50, 100, and 200 kg P ha-1) were applied as two forms of P fertilizer sources (triple superphosphate [TSP] and Ben-Guerir phosphate rock [BGPR]) in combination with weed control (weedy and weed-free). The results showed that the applied TSP and BGPR can increase tree needle P concentrations even when the needle P concentrations before fertiliser application were marginally higher than the critical P concentrations. The application of P fertilisers had no effect on tree growth during the two-year period of the trial, though it increased P. radiata needle P concentrations. However, the weed removal increased tree height, diameter at breast height, and basal area. In this plantation site the higher needle P concentrations than the critical P concentration suggests that the growth increase dueto weed removal treatment was probably due to an increase in the availability of soil water and nutrients other than P. The needle P concentrations of P. radiata can be predicted by soil tests, Bray-2 P, Olsen P, resin-Pi, and NaOH-Pi tests. Of these soil tests, Bray-2 P seems to be the best test in predicting soil P availability to P. radiata. The P concentrations in the needles had a relationship with the NaOH-Pi fraction but had no relationship with the H2SO4-Pi fraction. These results suggest that P. radiata was probably taking up P mainly from the pool of P-adsorbed to allophane and Fe+Al oxides (NaOH-Pi) in this high P-fixing acidic soil. © NISC (Pty) Ltd.

View description>>

Real world decisions often made in the presence of multiple, conflicting, and incommensurate criteria. Decision making requires multiple perspectives of different individuals as more decisions are made now in groups than ever before. This is particularly true when the decision environment becomes more complex such as sustainability policies study in environmental and energy sectors. Group decision making processes judgments or solutions for decision problems based on the input and feedback of multiple individuals. Multi-criteria decision and evaluation problems at tactical and strategic levels in practice involve fuzziness in terms of linguistic variables vis-à-vis criteria, weights, and decision maker judgments. Relevant alternatives or scenarios are evaluated according to a number of desired criteria. A fuzzy multi-criteria group decision software tool is developed to analyze long-term scenarios for Belgian energy policy in this paper.

A system of prefabricated vertical drains with surcharge preloading is an effective method for promoting radial drainage and accelerated soil consolidation. A piecewise technique is employed to analyse the radial consolidation in a multilayer soil system to include (i) the effect of soil downdrag and (ii) a smear zone having linearly varying soil permeability. The effect of soil dragged down from the upper soil layer into the lower layer has been analysed in terms of the time required for consolidation. It can be seen that the consolidation of the multilayer soil depends on smear zone characteristics, the permeability ratio between upper and lower soil layers, penetration depth, and drain spacing. Design procedures are described with the help of an example.

The paper presents a research recently completed by the authors utilizing a method of damage evaluation for identifying damage in timber bridges, numerically and experimentally. The method utilizes changes in modal strain energy between the undamaged and damaged states of plate-like structures. A finite element model of a laboratory timber bridge was developed to investigate the capabilities and limitations of the method to detect damage. A simple four-girder bridge was fabricated and tested in a laboratory to verify the method. The numerical studies showed that the method can correctly identify single and multiple damage locations within the bridge. The experimental studies also showed promising results for detecting severe damage, but less effective for light and medium damage.

Ability to offer a citizen-centric view of government model is the key to a successful e-government service. Life-event model is the most widely adopted paradigm supporting the idea of composing a single complex e-government service that corresponds to an event in a citizen's life. Elementary building blocks of Life-event are based on atomic services offered from multiple government agencies. This study found that methodological mechanics of service integration and in particular the requirements engineering for composite services has been overlooked. Purpose of this study is to define obstacles of achieving e-government service delivery integration, and suggests a framework based on ontological analysis and modelling. Proposed framework that shall be called E-Service Integration Modelling (E-SIM) is based on the extensive use of Life-event concept. This paper proposes a top-down abstraction approach in requirements elicitation and modelling to define and implement the phenomenon of Life-event in context of e-government.

We evaluated the prognostic accuracy of fracture risk assessment tool (FRAX™) and Garvan algorithms in an independent Australian cohort. The results suggest comparable performance in women but relatively poor fracture risk discrimination in men by FRAX™. These data emphasize the importance of external validation before widespread clinical implementation of prognostic tools in different cohorts. Introduction: Absolute risk assessment is now recognized as a preferred approach to guide treatment decision. The present study sought to evaluate accuracy of the FRAX™ and Garvan algorithms for predicting absolute risk of osteoporotic fracture (hip, spine, humerus, or wrist), defined as major in FRAX™, in a clinical setting in Australia. Methods: A retrospective validation study was conducted in 144 women (69 fractures and 75 controls) and 56 men (31 fractures and 25 controls) aged between 60 and 90 years. Relevant clinical data prior to fracture event were ascertained. Based on these variables, predicted 10-year probabilities of major fracture were calculated from the Garvan and FRAX™ algorithms, using US (FRAX-US) and UK databases (FRAX-UK). Area under the receiver operating characteristic curves (AUC) was computed for each model. Results: In women, the average 10-year probability of major fracture was consistently higher in the fracture than in the nonfracture group: Garvan (0.33 vs. 0.15), FRAX-US (0.30 vs. 0.19), and FRAX-UK (0.17 vs. 0.10). In men, although the Garvan model yielded higher average probability of major fracture in the fracture group (0.32 vs. 0.14), the FRAX™ algorithm did not: FRAX-US (0.17 vs. 0.19) and FRAX-UK (0.09 vs. 0.12). In women, AUC for the Garvan, FRAX-US, and FRAX-UK algorithms were 0.84, 0.77, and 0.78, respectively, vs. 0.76, 0.54, and 0.57, respectively, in men. Conclusion: In this analysis, although both approaches were reasonably accurate in women, FRAX™ discriminated fracture risk poorly in men. These data support the conc...

Gene expression profiling is rapidly evolving into a powerful technique for investigating tumor malignancies. The researchers are overwhelmed with the microarray-based platforms and methods that confer them the freedom to conduct large-scale gene expression profiling measurements. Simultaneously, investigations into cross-platform integration methods have started gaining momentum due to their underlying potential to help comprehend a myriad of broad biological issues in tumor diagnosis, prognosis, and therapy. However, comparing results from different platforms remains to be a challenging task as various inherent technical differences exist between the microarray platforms. In this paper, we explain a simple ratio-transformation method, which can provide some common ground for cDNA and Affymetrix platform towards cross-platform integration. The method is based on the characteristic data attributes of Affymetrix- and cDNA- platform. In the work, we considered seven childhood leukemia patients and their gene expression levels in either platform. With a dataset of 822 differentially expressed genes from both these platforms, we carried out a specific ratio-treatment to Affymetrix data, which subsequently showed an improvement in the relationship with the cDNA data.

Titanium dioxide (TiO2) under UV light irradiation is one of the effective treatment methods to reduce the concentration of synthetic organic compounds in water. Nevertheless, only a small amount of UV light is absorbed in the solar light. This makes the less use of TiO2 for environmental applications. In this study, we prepared Ru-doped visible light responsive (VLR) TiO2 to improve visible light absorption and characterized it in terms of physical and chemical properties. The photocatalytic activity of VLR Rudoped TiO2 was investigated to remove metsulfuron-methyl (MSM) in aqueous phase. The Ru-doped TiO2 at different Ru concentrations was found to have the anatase phase. The undoped and Ru-doped TiO2 consisted of regular round shape. The photocatalytic activity of VLR photocatalyst was significantly improved on the addition of Ru from 40% for undoped TiO2 to 80% for Ru-doped TiO2. The removal efficiency of MSM was proportional to the increasing Ru-doped TiO2 under visible light. As the calcined temperature increased from 300 to 900 â¦C, the degradation efficiencies moderately changed from 65 to 90%. However, the effect of calcination duration was marginal on the photodegradation of MSM.

In this paper, a Single-Hop Unequal Clustering (SHUC) algorithm is proposed for wireless sensor networks. The SHUC algorithm consists of three different parts. Firstly, an average energy factor is introduced to balance the residual energy of the whole network during the tentative cluster-head selection process, which improves the network energy efficiency. Secondly, a cost function is proposed to balance energy-efficiency of each node. Finally, an unequal clustering algorithm is proposed for single-hop homogeneous networks. Through both theoretical analysis and numerical results, it is shown that SHUC prolongs the network lifetime significantly against other clustering protocols such as LEACH-C and EECS. Under general instance, SHUC may prolong the lifetime by up to 30% against EECS and 70% against LEACH-C. © 2010 Binary Information Press.

In this paper, a grey fuzzy sliding mode controller (GFSMC) for brushless doubly fed motor (BDFM) adjustable speed system is presented. A grey model estimator and adaptive fuzzy control technology are incorporated into the sliding mode control (SMC) to adaptively regulate the adaptive law of SMC. The proposed adaptive fuzzy equivalent controller, adaptive fuzzy switching controller, and grey model compensation controller for BDFM can eliminate the average chattering encountered by most SMC schemes, improve the robustness, and obtain excellent static and dynamic performances of SMC. Simulation results show that the proposed control strategy is feasible, correct and effective.

Study objective: We assess the diagnostic accuracy of plasma neutrophil gelatinase-associated lipocalin (NGAL) to predict acute kidney injury in emergency department (ED) patients with suspected sepsis. Methods: We conducted a secondary analysis of a prospective observational study of a convenience sample of patients from 10 academic medical center EDs. Inclusion criteria were adult patients aged 18 years or older, with suspected infection or a serum lactate level greater than 2.5 mmol/L; 2 or more systemic inflammatory response syndrome criteria; and a subsequent serum creatinine level obtained within 12 to 72 hours of enrollment. Exclusion criteria were pregnancy, do-not-resuscitate status, cardiac arrest, or dialysis dependency. NGAL was measured in plasma collected at ED presentation. Acute kidney injury was defined as an increase in serum creatinine measurement of greater than 0.5 mg/dL during 72 hours. Results: There were 661 patient enrolled, with 24 cases (3.6%) of acute kidney injury that developed within 72 hours after ED presentation. Median plasma NGAL levels were 134 ng/mL (interquartile range 57 to 277 ng/mL) in patients without acute kidney injury and 456 ng/mL (interquartile range 296 to 727 ng/mL) in patients with acute kidney injury. Plasma NGAL concentrations of greater than 150 ng/mL were 96% sensitive (95% confidence interval [CI] 79% to 100%) and 51% (95% CI 47% to 55%) specific for acute kidney injury. In comparison, to achieve equivalent sensitivity with initial serum creatinine level at ED presentation required a cutoff of 0.7 mg/dL and resulted in specificity of 17% (95% CI 14% to 20%). Conclusion: In this preliminary investigation, increased plasma NGAL concentrations measured on presentation to the ED in patients with suspected sepsis were associated with the development of acute kidney injury. Our findings support NGAL as a promising new biomarker for acute kidney injury; however, further research is warranted. © 2009 American College...

The work by Christandl, K\'onig and Renner [Phys. Rev. Lett. 102, 020504 (2009)] provides in particular the possibility of studying unconditional security in the finite-key regime for all discrete-variable protocols. We spell out this bound from their general formalism. Then we apply it to the study of a recently proposed protocol [Laing et al., Phys. Rev. A 82, 012304 (2010)]. This protocol is meaningful when the alignment of Alice's and Bob's reference frames is not monitored and may vary with time. In this scenario, the notion of asymptotic key rate has hardly any operational meaning, because if one waits too long time, the average correlations are smeared out and no security can be inferred. Therefore, finite-key analysis is necessary to find the maximal achievable secret key rate and the corresponding optimal number of signals.

In this paper, we target the practical implementation issues of quantum multicast networks. First, we design a recursive lossless compression that allows us to control the trade-off between the circuit complexity and the dimension of the compressed quantum state. We give a formula that describes the trade-off, and further analyze how the formula is affected by the controlling parameter of the recursive procedure. Our recursive lossless compression can be applied in a quantum multicast network where the source outputs homogeneous quantum states (many copies of a quantum state) to a set of destinations through a bottleneck. Such a recursive lossless compression is extremely useful in the current situation where the technology of producing large-scale quantum circuits is limited. Second, we develop two lossless compression schemes that work for heterogeneous quantum states (many copies of a set of quantum states) when the set of quantum states satisfies a certain structure. The heterogeneous compression schemes provide extra compressing power over the homogeneous compression scheme. Finally, we realize our heterogeneous compression schemes in several quantum multicast networks, including the single-source multi-terminal model, the multi-source multi-terminal model, and the ring networks. We then analyze the bandwidth requirements for these network models.

A comprehensive investigation of electrocoagulation using sacrificial titanium (Ti) electrodes in wastewater was carried out. The effects of specific process variables, such as initial pH, mixing, current density, initial organic loading, and ionic/electrolyte strength were first optimized to produce recyclable Ti-based sludge. The sludge was incinerated at 600 °C to produce functional TiO2 photocatalyst. X-ray diffraction analysis revealed that TiO2 produced at optimum electrocoagulation conditions was mostly anatase structure. The specific surface area of the synthesized TiO 2 photocatalyst was higher than that of the commercially available and widely used Degussa P-25 TiO2. Furthermore, energy dispersive X-ray and X-ray photoelectron spectroscopy analyses showed that in additional to titanium and oxygen, this photocatalyst is also composed of carbon and phosphorus. These elements were mainly doped as a substitute site for the oxygen atom. Transmission electron microscopy images exhibited sharply edged nanorods, round nanoparticles, and nanotubes with nonuniform shapes showing some structural defects. Photodecomposition of gaseous acetaldehyde by this photocatalyst was also conducted under UV and visible light irradiation to study the photocatalytic properties of the doped TiO2 photocatalyst. While no photocatalytic activity was observed under visible light irradiation, this doped TiO2 photocatalyst exhibited high photocatalytic activity under UV light. © 2010 American Chemical Society.

© 2017 Techno-Press, Ltd. Organic fouling and biofouling pose a significant challenge to the membrane filtration process. Photocatalysis-membrane hybrid system is a novel idea for reducing these membranes fouling however, when TiO 2 photocatalyst nanoparticles are used in suspension, catalyst recovery is not only imposes an extra step on the process but also significantly contributes to increased membrane resistance and reduced permeate flux. In this study, TiO 2 photocatalyst has been immobilized by coating on the microfiltration (MF) membrane surface to minimize organic and microbial fouling. Nano-sized TiO 2 was first synthesized by a sol-gel method. The synthesized TiO 2 was coated on a Poly Vinyl Difluoride (PVDF) membrane (MF) surface using spray coating and dip coating techniques to obtain hybrid functional composite membrane. The characteristics of the synthesized photocatalyst and a functional composite membrane were studied using numerous instruments in terms of physical, chemical and electrical properties. In comparison to the clean PVDF membrane, the TiO 2 coated MF membrane was found more effective in removing methylene blue (20%) and E-coli (99%).

TiO2 from the incineration of dye wastewater flocculated sludge using TiCl4 coagulant was produced. Optimal catalyst amount and Pt-loading on TiO2 were studied for the production of H2 by photocatalytic reforming of methanol (6% vol.). On the other hand, BTSE (biologically treated sewage effluent) was flocculated using TiCl4 and produced sludge was incinerated to generate TiO2. TiO2 was loaded with optimum Pt and added to the supernatant in a photocatalytic reactor to test the efficiency of using remaining organics as a âsacrificial reagent❠for photocatalytic hydrogen production. Dissolved organic carbon (DOC) and molecular weight distribution (MWD) were measured for nanofiltration (NF) and TiCl4 flocculation followed by photocatalysis. TiO2 (from the incineration of BTSE flocculated sludge using TiCl4) was produced and loaded with 0.5% Pt. Results showed that the optimum concentration of TiO2 (from dye wastewater) for H2 production was 0.3 g/L, while the optimum amount of Pt was 0.5%. DOC and MWD removal was similar for the flocculation of BTSE followed by photocatalytic reaction and the NF process. Remaining organic compounds after flocculation could not be used as sacrificial reagent to induce H2 production. Further investigations on studying the UV intensity and/or identifying organic/inorganic scavengers to inhibit H2 production are underway.

This paper reviews risk-based approaches to assessing the risk acceptability and cost-effectiveness of protective measures for infrastructure. The paper describes three risk acceptance criteria based on fatality risks, failure probabilities and net benefit assessment. These criteria can be applied to any item of infrastructure such as buildings, bridges, dams, offshore platforms, etc. and also applies to any man-made or natural hazard such as earthquakes, cyclones, terrorism, floods and so on. The decision support framework accompanying these risk acceptance criteria considers hazard and threat probabilities, value of human life, physical and indirect damages, risk reduction and protective measure costs. This has specific utility for the safety and economical design and assessment of new and existing protective structures against shock and impact loading. Risk assessments are conducted for a bridge over an inland waterway where the hazard is ship impact and a building subject to terrorist attack. The illustrative examples showed under what combination of risk reduction, and fatality and damage costs the fatality and failure risks would be acceptable, and when protective measures would be cost-effective.

The paper describes risk-informed decision support for assessing the costs and benefits of counter-terrorism (CT) protective measures for infrastructure. Such a decision support framework needs to consider threat scenarios and probabilities, value of human life, physical (direct) damage, indirect damage, risk reduction and protective measure costs. Probabilistic terrorism risk assessments that quantify the costs and benefits are conducted for three items of infrastructure using representative cost and vulnerability data. The illustrative examples show under what combination of risk reduction, threat probability, and fatality and damage costs the CT protective measures would be cost-effective for United States building, bridge and aviation infrastructure. It was found that if indirect losses (such as business interruption, loss of GDP, etc.) are considered, then CT protective measures are cost-effective even if the terrorist threat probability is not high. Opportunity costs can be considerable, which makes CT protective measures less cost-effective. © 2009 Elsevier B.V. All rights reserved.

Increases in wind damage are expected if the intensity and/or frequency of tropical cyclones increase due to enhanced greenhouse conditions (climate change). The paper proposes a methodology to estimate cyclone damage risks due to enhanced greenhouse conditions using residential construction in the North Queensland cities of Cairns, Townsville and Mackay as a case study, and then assesses the economic viability of several climate adaptation strategies. The analysis includes probabilistic modelling of cyclone intensity and frequency, time-dependent increase in wind speed from enhanced greenhouse conditions (global warming), and vulnerability functions of building damage. Increases in mean annual maximum wind speed from 0% to 25% over 50 years are considered to represent the uncertainty in changing wind hazard patterns as a result of climate change. The effect of regional changes to building inventory over time and space, rate of retrofitting, cost of retrofit, reduction in vulnerability, and discount rate will be considered. The risk-cost-benefit analysis considering temporal changes in wind hazard and building vulnerability can be used to help optimise the timing and extent of climate adaptation strategies. © Institution of Engineers Australia, 2010.

Heart rate is one of the major indications of human cardiovascular response to exercises. This study investigates human heart rate response dynamics to moderate exercise. A healthy male subject has been asked to walk on a motorised treadmill under a predefined exercise protocol. ECG, body movements, and oxygen saturation (SpO2) have been reliably monitored and recorded by using non-invasive portable sensors. To reduce heart rate variation caused by the influence of various internal or external factors, the designed step response protocol has been repeated three times. Experimental results show that both steady state gain and time constant of heart rate response are not invariant when walking speed is faster than 3 miles/hour, and time constant of offset exercise is noticeably longer than that of onset exercise.

View description>>

With the rapid development of heterogeneous networks, multimode terminals become more and more popular. However, when there are several different kinds of sessions requiring transmission simultaneously, how to distribute these session flows among the available interfaces of the terminal according to the different features of the flows, the current conditions of the candidate access networks, the communication monetary cost and power consumption is a new challenge. This paper proposes a new solution to the flow distribution problem for multimode terminals. The proposal includes an architecture model of the multimode terminal as well as the corresponding flow distribution algorithm. The proposal utilizes the notion of priority, ensuring the more important sessions have preferential use of the network resources when the traffic intensity was high. In addition, the proposal introduces a new mechanism to automatically determine the weights of different attributes which influences the flow distribution decision making, thus avoiding the difficulty to specify the weights manually. Simulation results show that the proposal can efficiently distribute the session flows on a multimode mobile terminal to the appropriate networks for transmission. Also, the proposal provides a significant improvement to performance indicators such as throughput and session completion rate.

We estimated the current prevalence of type 2 diabetes in the Vietnamese population and developed simple diagnostic models for identifying individuals at high risk of undiagnosed type 2 diabetes. The study was designed as a cross-sectional investigation with 721 men and 1,421 women, who were aged between 30 and 72 years and were randomly sampled from Ho Chi Minh City (formerly Saigon) in Vietnam. A 75 g oral glucose tolerance test to assess fasting and 2 h plasma glucose concentrations were determined for each individual. The ADA diagnostic criteria were used to determine the prevalence of type 2 diabetes. WHR and blood pressure were also measured in all individuals. The prevalence of type 2 diabetes was 10.8% in men and 11.7% in women. Higher WHR and blood pressure were independently associated with a greater risk of type 2 diabetes. Compared with participants without central obesity and hypertension, the odds of diabetes was increased by 6.4-fold (95% CI 3.2-13.0) in men and 4.1-fold (2.2-7.6) in women with central obesity and hypertension. Two nomograms were developed that help identify men and women at high risk of type 2 diabetes. The current prevalence of type 2 diabetes in the Vietnamese population is high. Simple field measurements such as waist-to-hip ratio and systolic blood pressure can identify individuals at high risk of undiagnosed type 2 diabetes.

Receiver operating characteristic (ROC) curve, plotting true positive rates against false positive rates as threshold varies, is an important tool for evaluating biomarkers in diagnostic medicine studies. By definition, ROC curve is monotone increasing from 0 to 1 and is invariant to any monotone transformation of test results. And it is often a curve with certain level of smoothness when test results from the diseased and non-diseased subjects follow continuous distributions. Most existing ROC curve estimation methods do not guarantee all of these properties. One of the exceptions is Du and Tang (2009) which applies certain monotone spline regression procedure to empirical ROC estimates. However, their method does not consider the inherent correlations between empirical ROC estimates. This makes the derivation of the asymptotic properties very difficult. In this paper we propose a penalized weighted least square estimation method, which incorporates the covariance between empirical ROC estimates as a weight matrix. The resulting estimator satisfies all the aforementioned properties, and we show that it is also consistent. Then a resampling approach is used to extend our method for comparisons of two or more diagnostic tests. Our simulations show a significantly improved performance over the existing method, especially for steep ROC curves. We then apply the proposed method to a cancer diagnostic study that compares several newly developed diagnostic biomarkers to a traditional one. © 2010 Elsevier B.V.

Uncertainty relations give upper bounds on the accuracy by which the outcomes of two incompatible measurements can be predicted. While established uncertainty relations apply to cases where the predictions are based on purely classical data (e.g., a description of the system's state before measurement), an extended relation which remains valid in the presence of quantum information has been proposed recently [Berta et al., Nat. Phys. 6, 659 (2010)]. Here, we generalize this uncertainty relation to one formulated in terms of smooth entropies. Since these entropies measure operational quantities such as extractable secret key length, our uncertainty relation is of immediate practical use. To illustrate this, we show that it directly implies security of a family of quantum key distribution protocols including BB84. Our proof remains valid even if the measurement devices used in the experiment deviate arbitrarily from the theoretical model.

The Leftover Hash Lemma states that the output of a two-universal hash function applied to an input with sufficiently high entropy is almost uniformly random. In its standard formulation, the lemma refers to a notion of randomness that is (usually implicitly) defined with respect to classical side information. Here, we prove a (strictly) more general version of the Leftover Hash Lemma that is valid even if side information is represented by the state of a quantum system. Furthermore, our result applies to arbitrary delta-almost two-universal families of hash functions. The generalized Leftover Hash Lemma has applications in cryptography, e.g., for key agreement in the presence of an adversary who is not restricted to classical information processing.

AbstractA new class of regulatory molecules known as microRNAs (miRNAs) is redefining our understanding of the molecular pathways associated with tumorigenesis. These miRNAs are small noncoding RNA (ncRNA) sequences with potent regulatory potential. The aberrant expression of miRNAs has been associated with the development of various tumors. It has been suggested that miRNAs can both regulate and act as tumor‐suppressor genes and oncogenes. Our understanding of the role of miRNAs in head and neck tumorigenesis is in its infancy. However, several recent studies have revealed extensive dysregulation of miRNA in head and neck tumors and have highlighted the potential of certain miRNAs to act as diagnostic and prognostic markers and targets for new therapeutic agents. The intent of this review is to discuss and summarize current findings that point to a significant role for miRNAs in head and neck tumorigenesis. © 2010 Wiley Periodicals, Inc. Head Neck, 2010

In rail track environments the loading system is cyclic unlike the monotonie seepage force that usually occurs in embankment dams. The mechanisms of filtration, interface behaviour and time-dependent changes of the drainage and filtration properties occurring within the filter medium require further research to improve the design guidelines. A novel cyclic process simulation filtration apparatus was designed and commissioned at the University of Wollongong, and a standard testing procedure was established. The test apparatus was designed to simulate heavy haul train operations. Key parameters that influence the change in porosity and pore water pressure within the subballast layer under cyclic conditions in rail track environments were identified.

View description>>

The hydraulic conductivity (k) of a fully saturated granular material can be predicted by the well-known Kozeny–Carman formula, and its slightly different variations, based on the porosity (n) and effective diameter (deff). Most variations of the Kozeny–Carman formula compute the parameter deff based on a given conventional particle size distribution by mass (PSDm), where the validation would normally be carried out by comparing against laboratory permeability tests conducted on soils having an average coefficient of uniformity (Cu) of about 3. Knowing that the Kozeny–Carman formula was originally developed for uniformly graded materials, inevitable limitations are inherited when it is applied to increasingly graded soils. This study proposes to convert the PSDm into its equivalence in surface area (PSDsa) conforming to the fundamental geometric assumption by which the Kozeny–Carman equation was originally formulated. The estimated deff based on this proposed PSDsa method appears implicitly to incorporate the size, shape and angularity of the natural grains which were traditionally represented by the shape coefficient (α). The results presented in this paper show that the suggested method is capable of predicting k for fully saturated granular soils with Cu of up 20.

The paper shows an optimality of the proposed tests of hypothesis. We demonstrate that our approach can be easily applied to practical studies, because execution of the tests does not require deriving of asymptotical analytical solutions regarding the type I error.

Internal erosional behaviour of a lignosulfonate-treated dispersive soil has been studied using apparatus designed and built at University of Wollongong. The effectiveness of lignosulfonate-treated dispersive clay on its erosion resistance has been investigated and its advantages over traditional admixtures (cement) have been presented. Lignosulfonate is a non-toxic admixture that can stabilise certain erodible and dispersive soils effectively, without causing any adverse environmental impact on the ground unlike some traditional stabilisers. Test results show that the erosional parameters such as critical shear stress and coefficient of soil erosion are improved with the increase in the amount of lignosulfonate. Knowledge about the clay particles and lignosulfonate interaction mechanisms is pertinent for long-term environmental sustainability of treated soils, a factor which is poorly understood at microscopic level. Considering this, X-ray diffraction, and Fourier transform infrared spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy were carried out on representative samples to understand the stabilisation mechanism at the particle scale level. The improvement of performance exhibited by the lignosulfonate-treated soil can be mainly attributed to the reduction of the double-layer thickness by the neutralisation of surface charges of the clay particles and the formation of more stable particle clusters by polymer bridging.

View description>>

Barron (Trans ASCE 113:718-724, 1948) theoretical relationship between degree of consolidation (Ur) and time factor (Tr) is generally used to determine the coefficient of radial consolidation cr. Several researchers have proposed different laboratory techniques for obtaining the value of cr. However, the usual approach is to compare some salient features of the theoretical Ur-Tr relationship with the compression, δ and time, t based on the laboratory data. In this paper, rapid consolidation test procedure originally proposed by Su (J Soil Mech Found Div Am Soc Civ Eng No. 95: Proc. Pap. 1729 (1-9), 1958) to determine the coefficient of vertical consolidation (cv) is extended to evaluate Barron's coefficient of radial consolidation cr for the case of equal strain. The characteristic feature of the proposed method is the identification of the steepest tangent from the δ-log t plot. The slope of steepest tangent is independent of the drain spacing ratio (n) with a value of 0.847. This approach is rapid, and it predicts more reliable values of cr as it is less influenced by the secondary compression. In addition, this method is more versatile and can be applied for consolidation trends which do not always exhibit the typical S-shape. © 2010 Springer Science+Business Media B.V.

Earth science often deals with complex systems spanning multiple disciplines. These systems are best described by integrated models built with contributions from specialists of many backgrounds. But building integrated models can be difficult; modular and hierarchical approaches help to manage the increasing complexity of these modeling systems, but there is a need for framework and integration methods and standards to support modularity. Complex models require many data and generate lots of output, so software and standards are required for data handling, model output, data distribution services, and user interfaces. Complex modeling systems must be efficient to be useful, so they require contributions by software engineers to ensure efficient architectures, accurate numerics, and implementation on fast computers. Further, integrated model systems can be difficult to learn and use unless adequate documentation, training, and support are provided.

The nonlinear dynamic circuit model of the superconductor is established. In the circuit model, the hysteresis inductance and hysteresis loss described by using simplified Preisach Model are deduced. Applying the hysteresis circuit model, the currents flowing in different superconductor layers of high temperature superconducting cable are simulated, as well as the hysteresis loss of the superconducting cable. The simulation results are verified by comparison with the data recorded in literatures. Finally, the influences of hysteresis on superconducting cable are analyzed and discussed. © 2010 - IOS Press and the authors. All rights reserved.

We introduce a new method to model permanent-magnet synchronous machines (PMSMs) with saliencies due to the salient structure and magnetic saturation. We define two parameters to indicate these saliencies, i.e., the structural saliency ratio $(K_{rm str})$ and the saturation saliency ratio $(K_{rm sat})$. To verify the nonlinear model, we tested a real PMSM and numerically simulated it. The nonlinear inductance matrix is deduced and expressed by a nonlinear function regressed from the experimental data. The simulation and experimental results agree well with each other.

The Least Relative Residual Sum of Square (LRRSS) method is employed in the nonlinear inductance function regression. After experimentally identifying out all the parameters, a nonlinear mathematic model of SPMSMis built up. Furthermore, the direct torque control (DTC) scheme is applied to this new model to verify the model and simulate the machine performance.

Research in identifying the relative importance of criteria used to select a preferred supplier has, for the most part, relied on subjective lists of criteria being presented to respondents. The research reported here uses an experimental design approach to quantify the importance of nine common criteria used in an actual evaluation and selection of a contractor/supplier. Unique choice sets were constructed, each comprising three tender evaluation outcomes (alternatives) described in terms of all criteria, but with varying levels. Respondents simultaneously evaluated all three alternatives within each choice set and selected the most preferred. Utility estimates for each criterion level were determined as was the overall contribution made by the individual criterion. Results indicate Past Project Performance, Technical Expertise and Cost are the most important criteria in an actual choice of contractor with Organisational Experience, Workload, and Reputation being the least important.

The deformation of oxide scale affects roll-strip interface characteristics in hot rolling. Few studies have been carried out on the deformation behavior of oxide scale in hot rolling of stainless steels. In this paper, the thickness, morphology of the oxide scale and the surface roughness of workpiece in hot rolling of stainless steel 304 under the condition of a single pass were investigated, and the friction coefficients were calculated. The effect of humidity on the growth of oxide scale of stainless steel 304 has been identified. Outer and inner oxide layers can be found when the water vapor content is over 7 vol.%. An incomplete oxide layer which is a transition layer between the inner oxide layer and steel substrate can be distinguished in thick oxide scale when the water vapour content is over 12 vol.%. The oxide scale thickness decreases linearly with an increase of reduction. Surface roughness also decreases with an increase of reduction. After experiencing 20 and 30 % reduction, the surface roughness asperities are flattened, so the outmost surface of oxide scale after rolling is much smoother than that before rolling. Generally, friction coefficients decrease with an increase of reduction.

Numerical simulations are carried out to estimate the response and damage of unreinforced brick masonry walls subjected to explosive blast loading based on the transient dynamic finite element program LS-DYNA. A previously developed dynamic plastic damage model was used for brick and mortar. A new model for strain rate effects of bricks and mortar is included in the numerical analysis. The results obtained from the numerical models are compared with field test data and good agreement can be found. Parametric studies are conducted to evaluate the effect of material strength, boundary conditions, and thickness of the wall on the blast response of unreinforced brick masonry walls. It was found that boundary conditions and wall thickness significantly affect the blast response, while the effect of material strength is relatively small. © 2010 Elsevier Ltd. All rights reserved.

The discoloring interaction between the artist's pigments cadmium yellow and the copper-containing malachite, an interaction that is conjectured to cause black spotting in oil paintings of the 19th and early 20th centuries, was examined using X-ray mapping and scatter diagram analysis. The application of these coupled techniques confirmed that copper sulfide phases were produced during discoloration reaction. Scatter diagram analysis indicated that two copper sulfide stoichiometries (CuS and Cu3S2) were present as reaction products where previously only crystalline CuS (covellite) had been identified by X-ray diffraction. The results demonstrate the potential of X-ray mapping coupled with scatter diagram analysis for the identification of both crystalline and X-ray amorphous phases produced by such complex heterogeneous interactions and their applicability to the investigation of interactions of artists' pigments. © Microscopy Society of America 2010.

Collins and Popescu realized a powerful analogy between several resources in classical and quantum information theory. The Collins-Popescu analogy states that public classical communication, private classical communication, and secret key interact with one another somewhat similarly to the way that classical communication, quantum communication, and entanglement interact. This paper discusses the information-theoretic treatment of this analogy for the case of noisy quantum channels. We determine a capacity region for a quantum channel interacting with the noiseless resources of public classical communication, private classical communication, and secret key. We then compare this region with the classical-quantum-entanglement region from our prior efforts and explicitly observe the information-theoretic consequences of the strong correlations in entanglement and the lack of a super-dense coding protocol in the public-private-secret-key setting. The region simplifies for several realistic, physically-motivated channels such as entanglement-breaking channels, Hadamard channels, and quantum erasure channels, and we are able to compute and plot the region for several examples of these channels.

The dynamic capacity theorem characterizes the reliable communication rates of a quantum channel when combined with the noiseless resources of classical communication, quantum communication, and entanglement. In prior work, we proved the converse part of this theorem by making contact with many previous results in the quantum Shannon theory literature. In this work, we prove the theorem with an 'ab initio' approach, using only the most basic tools in the quantum information theorist's toolkit: the Alicki-Fannes' inequality, the chain rule for quantum mutual information, elementary properties of quantum entropy, and the quantum data processing inequality. The result is a simplified proof of the theorem that should be more accessible to those unfamiliar with the quantum Shannon theory literature. We also demonstrate that the 'quantum dynamic capacity formula' characterizes the Pareto optimal trade-off surface for the full dynamic capacity region. Additivity of this formula simplifies the computation of the trade-off surface, and we prove that its additivity holds for the quantum Hadamard channels and the quantum erasure channel. We then determine exact expressions for and plot the dynamic capacity region of the quantum dephasing channel, an example from the Hadamard class, and the quantum erasure channel.

An unexpected breakdown in the existing theory of quantum serial turbo coding is that a quantum convolutional encoder cannot simultaneously be recursive and non-catastrophic. These properties are essential for quantum turbo code families to have a minimum distance growing with blocklength and for their iterative decoding algorithm to converge, respectively. Here, we show that the entanglement-assisted paradigm simplifies the theory of quantum turbo codes, in the sense that an entanglement-assisted quantum (EAQ) convolutional encoder can possess both of the aforementioned desirable properties. We give several examples of EAQ convolutional encoders that are both recursive and non-catastrophic and detail their relevant parameters. We then modify the quantum turbo decoding algorithm of Poulin et al., in order to have the constituent decoders pass along only 'extrinsic information' to each other rather than a posteriori probabilities as in the decoder of Poulin et al., and this leads to a significant improvement in the performance of unassisted quantum turbo codes. Other simulation results indicate that entanglement-assisted turbo codes can operate reliably in a noise regime 4.73 dB beyond that of standard quantum turbo codes, when used on a memoryless depolarizing channel. Furthermore, several of our quantum turbo codes are within 1 dB or less of their hashing limits, so that the performance of quantum turbo codes is now on par with that of classical turbo codes. Finally, we prove that entanglement is the resource that enables a convolutional encoder to be both non-catastrophic and recursive because an encoder acting on only information qubits, classical bits, gauge qubits, and ancilla qubits cannot simultaneously satisfy them.

The authors have previously reported the effectiveness of using self and peer assessment to improve learning outcomes by providing opportunities to practise, assess and provide feedback on students' attribute development. Despite this work and the research of others, a significant number of students and, indeed, many academics focus on the free-rider deterrent capability of self and peer assessment, rather than its capacity to provide opportunities for developing judgement and facilitating reflection and feedback to complete the learning cycle. The advent of web-based tools such as SPARKPLUS allows the frequent and efficient implementation of self and peer assessment activities even in large classes. This article reports the results of an investigation into whether the regular use of self and peer assessment in different contexts promoted effective peer learning, increased engagement and encouraged students to learn.

Diminished bite force has been considered a defining feature of modern Homo sapiens , an interpretation inferred from the application of two-dimensional lever mechanics and the relative gracility of the human masticatory musculature and skull. This conclusion has various implications with regard to the evolution of human feeding behaviour. However, human dental anatomy suggests a capacity to withstand high loads and two-dimensional lever models greatly simplify muscle architecture, yielding less accurate results than three-dimensional modelling using multiple lines of action. Here, to our knowledge, in the most comprehensive three-dimensional finite element analysis performed to date for any taxon, we ask whether the traditional view that the bite of H. sapiens is weak and the skull too gracile to sustain high bite forces is supported. We further introduce a new method for reconstructing incomplete fossil material. Our findings show that the human masticatory apparatus is highly efficient, capable of producing a relatively powerful bite using low muscle forces. Thus, relative to other members of the superfamily Hominoidea, humans can achieve relatively high bite forces, while overall stresses are reduced. Our findings resolve apparently discordant lines of evidence, i.e. the presence of teeth well adapted to sustain high loads within a lightweight cranium and mandible.

Although the distributions of peak incident overpressure and impulse generated from spherical charges and cylindrical charges of the same weight can differ greatly close to the point of detonation, spherical charges are assumed for nearly all explosive-effects computations per modern standards for blast-resistant design such as UFC-3-340-02 and the soon-to-be published ASCE Standard for the Blast Protection of Buildings. A blast-testing program was performed using a reinforced concrete slab as the target to investigate the reflected peak overpressure and impulse distributions as a function of charge shape, orientation, and scaled distance. The charge shapes were cylindrical and spherical, and the charge mass varied from 0.24 to 8.0 kg. Nine pressure transducers were installed on the surface of the slab to record the distribution of pressure histories over the face of the target. A finite element model of the explosive and the target was validated using the experimental data. The validated model was then used to undertake a parametric analysis to more broadly study the effects of detonation point, ratio of charge length to charge diameter, charge orientation and standoff distance on the distribution of reflected overpressure. Numerical results are compared with predictions of UFC-3-340-02. For cylindrical charges, the ratio of charge length ( L) to diameter ( D), the orientation of the longitudinal axis of the charge, and detonation point within the charge affected the distributions of reflected peak overpressure and impulse in the immediate vicinity of the explosive. The UFC-3-340-02 underpredicts substantially the reflected peak overpressure and impulse on a target aligned with the vertical axis of a cylindrical charge with an aspect ratio of 1.0.

In this study, laboratory-scale anaerobic fluidized bed bioreactors (AFBBRs) using granular activated carbon as bedding material were employed for treating a primary treated sewage effluent (PTSE) with or without refractory organic pollutants (ROPs). A new starch based flocculant (NSBF) combining a nature starch based cationic flocculants and trace nutrients was prepared and applied in the AFBBR. The impact of NSBF on the performance of AFBBR was mainly evaluated in terms of organic and nutrient removal and microbial activity. Membrane fouling based on critical flux was assessed when the bioreactor used as pretreatment for microfiltration. The results indicated that the addition of NSBF in AFBBR (NSBF-AFBBR) not only attained improved organic (9-10%) and nutrient removal (10-20%), higher biomass growth (3.0 gbiomass/LGAC) and net bed expansion (18 cm), but also doubled the critical flux (from 15 L/m3 h to 30 L/m3 h) in the microfiltration system. In addition, NSBF-AFBBR could retain 10% better DOC removal efficiency at different recirculation rates for treating PTSE with ROPs. When increasing organic loading rate from 21.6 kg COD/m3 d to 43.2 kg COD/m3 d, NSBF-AFBBR achieved comparatively constant organic removal of 55% whereas the efficiency in AFBBR alone decreased dramatically from 47% to 34%. Thus, NSBF could act as a performance enhancer for AFBBR. © 2010 Elsevier B.V. All rights reserved.

In many image processing applications, the structures conveyed in the image contour can often be described by a set of connected ellipses. Previous fitting methods to align the connected ellipse structure with a contour, in general, lack a continuous solution space. In addition, the solution obtain often satisfies only a partial number of ellipses, leaving others with poor fits. In this paper, we address these two problems by presenting an iterative framework for fitting a 2D silhouettte contour to a pre-specified connected ellipses structure with a very coarse initial guess. Under the proposed framework, we first improve the initial guess by modelling the silhouette region as set of disconnected ellipses using mixture of Gaussian densities or the heuristics approaches. Then, an iterative method is applied in a similar fashion to the Iterative Closest Point (ICP) (Alshawa, 2007; Li and Griffiths, 2000; Besl and McKay, 1992) algorithm. Each iteration contains two parts: first part is to assighn all the contour points to the individual unconnected ellipses, which we refer to as the segmentation step and the second part is the non-linear least square approach that minimizes both the sum of the square distance between the countour points and ellipse's edge as well as minimizing the ellipse's vertex pair(s) distances, which we refer to as the minimization step. We illustrate the effectiveness of our menthods through experimental result on several images as well as applying the algorithm to a mini database of human upper-body images.

Single-sided linear induction motors (SLIMs) have lately been applied in transportation system traction drives, particularly in the intermediate speed range. This is because they have merits, such as the ability to exert thrust on the secondary without mechanical contact, high acceleration or deceleration, less wheel wear, small turning circle radius, and flexible road line. The theory of operation for these machines can be directly derived from rotary induction motors (RIMs). However, while the cut-open primary magnetic circuit has many inherent characteristics of the RIM equivalent circuits, several issues involving the transversal edge and longitudinal end effects and the half-filled slots at the primary ends need to be investigated. In this paper, a T-model equivalent circuit is proposed which is based on the 1-D magnetic equations of the air gap, where half-filled slots are considered by an equivalent pole number. Among the main five parameters, namely, the primary resistance, primary leakage inductance, mutual inductance, secondary resistance, and secondary inductance, the mutual inductance and the secondary resistance are influenced by the edge and end effects greatly, which can be revised by four relative coefficients, i.e., Kr, Kx, Cr, and Cx. Moreover, two-axis equivalent circuits (dq or αβ) according to the T-model equivalent circuit are obtained using the power conversion rule, which are analogous with those of the RIM in a two-axis coordinate system. The linear induction motor dynamic performance, particularly the mutual inductance and the secondary resistance, can be analyzed by the four coefficients. Experimental verification indicates that both the T-model and the new two-axis circuits are reasonable for describing the steady and dynamic performance of the SLIM. These two models can provide good guidance for the electromagnetic design and control scheme implementation for SLIM applications.

As a new version of support vector machine (SVM), least squares SVM (LS-SVM) involves equality instead of inequality constraints and works with a least squares cost function. A well-known drawback in the LSSVM applications is that the sparseness is lost. In this paper, we develop an adaptive pruning algorithm based on the bottom-to-top strategy, which can deal with this drawback. In the proposed algorithm, the incremental and decremental learning procedures are used alternately and a small support vector set, which can cover most of the information in the training set, can be formed adaptively. Using this set, one can construct the final classifier. In general, the number of the elements in the support vector set is much smaller than that in the training set and a sparse solution is obtained. In order to test the efficiency of the proposed algorithm, we apply it to eight UCI datasets and one benchmarking dataset. The experimental results show that the presented algorithm can obtain adaptively the sparse solutions with losing a little generalization performance for the classification problems with no-noises or noises, and its training speed is much faster than sequential minimal optimization algorithm (SMO) for the large-scale classification problems with no-noises.

In this paper, we propose a new method to recognize gestures of cartoon images with two practical applications, i.e., content-based cartoon image retrieval and interactive cartoon clip synthesis. Upon analyzing the unique properties of four types of features including global color histogram, local color histogram (LCH), edge feature (EF), and motion direction feature (MDF), we propose to employ different features for different purposes and in various phases. We use EF to define a graph and then refine its local structure by LCH. Based on this graph, we adopt a transductive learning algorithm to construct local patches for each cartoon image. A spectral method is then proposed to optimize the local structure of each patch and then align these patches globally. MDF is fused with EF and LCH and a cartoon gesture space is constructed for cartoon image gesture recognition. We apply the proposed method to content-based cartoon image retrieval and interactive cartoon clip synthesis. The experiments demonstrate the effectiveness of our method.

With the rapid development of various optical, infrared, and radar sensors and GPS techniques, there are a huge amount of multidimensional uncertain data collected and accumulated everyday. Recently, considerable research efforts have been made in the field of indexing, analyzing, and mining uncertain data. As shown in a recent book on uncertain data, in order to efficiently manage and mine uncertain data, effective indexing techniques are highly desirable. Based on the observation that the existing index structures for multidimensional data are sensitive to the size or shape of uncertain regions of uncertain objects and the queries, in this paper, we introduce a novel R-Tree-based inverted index structure, named UI-Tree, to efficiently support various queries including range queries, similarity joins, and their size estimation, as well as top-k range query, over multidimensional uncertain objects against continuous or discrete cases. Comprehensive experiments are conducted on both real data and synthetic data to demonstrate the efficiency of our techniques.

Loop is a powerful program construct in classical computation, but its power is still not exploited fully in quantum computation. The exploitation of such power definitely requires a deep understanding of the mechanism of quantum loop programs. In this paper, we introduce a general scheme of quantum loops and describe its computational process. The function computed by a quantum loop is defined, and a denotational semantics and a weakest precondition semantics of a quantum loop are given. The notions of termination and almost termination are proposed for quantum loops. This paper only consider the case of finite-dimensional state spaces. Necessary and sufficient conditions for termination and almost termination of a general quantum loop on any mixed input state are presented. A quantum loop is said to be (almost) terminating if it (almost) terminates on any input state. We show that a quantum loop is almost terminating if and only if it is uniformly almost terminating. It is observed that a small disturbance either on the unitary transformation in the loop body or on the measurement in the loop guard can make any quantum loop (almost) terminating, provided that some dimension restriction is satisfied. Moreover, a representation of the function computed by a quantum loop is given in terms of finite summations of matrices. To illustrate the notions and results obtained in this paper, two simple classes of quantum loop programs, one qubit quantum loops, and two qubit quantum loops defined by controlled gates, are carefully examined, and to show their expressive power, quantum loops are applied in describing quantum walks.

The magnetic flux density B and magnetic field strength H loci under alternating and rotating magnetizations are measured by using an improved 3-D tester. The magnetic reluctivity tensor can be expressed by a second-order three-dimensional full rank matrix by means of the experimental results. Taking the off-diagonal elements into account can benefit to accurate numerical analysis of magnetic field in 3-D flux electrical machines.

Distance measurement methodologies based on the digital camera usually require time-consuming calibration procedures, some are even derived from complicated image processing algorithms resulting in low picture frame rates. In a dynamic camera system, due to the unpredictability of intrinsic and extrinsic parameters, odometric results are highly dependent on the quality of extra sensors. In this paper, a simple and efficient algorithm is proposed for relative distance estimation in robotic active vision by using a monocular digital camera. Accuracy of the estimation is achieved by judging the 2D perspective projection image ratio of the robot labels obtained on a TFT-LCD (Thin Film Transistor – Liquid Crystal Display) monitor without the need of any additional sensory cost and complicated calibration effort. Further, the proposed algorithm does not contain any trigonometric functions so that it can be easily implemented on an embedded system using the Field Programmable Gate Array (FPGA) technology. Experimental results are included to demonstrate the effectiveness of the technique.

The safety and reliability of reinforced grouted concrete block masonry is not accurately known in China. The present paper develops a probabilistic model to calculate the structural reliability of typical reinforced grouted concrete block masonry walls designed to Chinese standards, loaded concentrically and eccentrically in compression. The effect of probability distribution of model error, material strengths, live load type, structural safety class, live-to-dead ratio, reinforcement ratio, discretization of wall thickness, eccentricity and load effect combination were considered when calculating the structural reliability of reinforced grouted concrete block masonry walls in compression. When using the recommended distribution of model error for typical structures the existing (design) safety levels were found to be close to the target reliability for concentric compression for second class safety grade structures which comprise the majority of building stock in China. However, the reliability-based code calibration showed that design loads could be increased and decreased by 13.6% and 16.7% for first and third class safety grade structures, respectively. © 2009 Elsevier Ltd.

Classic bilevel programming deals with two level hierarchical optimization problems in which the leader attempts to optimize his/her objective, subject to a set of constraints and his/her followerâs solution. In modelling a real-world bilevel decision problem, some uncertain coefficients often appear in the objective functions and/or constraints of the leader and/or the follower. Also, the leader and the follower may have multiple conflicting objectives that should be optimized simultaneously. Furthermore, multiple followers may be involved in a decision problem and work cooperatively according to each of the possible decisions made by the leader, but with different objectives and/or constraints. Following our previous work, this study proposes a set of models to describe such fuzzy multi-objective, multi-follower (cooperative) bilevel programming problems. We then develop an approximation Kth-best algorithm to solve the problems.

Trilevel programming refers to hierarchical optimization problems in which the top-level, middle-level, and bottom-level decision entities all attempt to optimize their individual objectives, but are impacted by the actions and partial control exercised by decision entities located at other levels. To solve this complex problem, in this study first we propose the use of a general linear trilevel programming (LTLP) subsequently, we develop a trilevel Kth-best algorithm to solve LTLP problems. A user-friendly trilevel decision support tool is also developed. A case study further illustrates the effectiveness of the proposed method. © 2009 Elsevier Inc. All rights reserved.

Chloride-induced corrosion in reinforced concrete leads to a reduction of the steel cross-section and deterioration of the steel–concrete bond. In this paper, experimental results are presented in order to clarify the respective influence of these degradations on beam serviceability (deflection). Pitting corrosion simulations were performed and two naturally corroded beams (14 and 23 years old) were analysed. Corrosion simulations have shown that the reduction in steel cross-section due to local pitting corrosion does not affect serviceability. Increased deflection is due to deterioration of the steel-concrete bond (reduction of concrete tension stiffening). Experimental results obtained on two corroded beams broken and analysed after 14 years and 23 years of chloride exposure showed that, during the natural chloride-induced corrosion process, the corrosion pattern evolves in relation to the corrosion cracking. Localised pitting corrosion is responsible for the initiation of corrosion cracking. Then, as the width of the cracks develops, general corrosion becomes gradually the main corrosion pattern. According to these experimental results, a mechanical model is proposed for serviceability assessment, which takes into account the evolution of the corrosion pattern from local pitting corrosion to general reinforcement corrosion.

The evaluation of solutions is an important phase in power distribution system planning (PDSP) which allows issues such as quality of supply, cost, social service and environmental implications to be considered and usually involves the judgments of a group of experts. The planning problem is thus suitable for the multi-criteria group decision-making (MCGDM) method. The evaluation process and evaluation criteria often involve uncertainties incorporated in quantitative analysis with crisp values and qualitative judgments with linguistic terms; therefore, fuzzy sets techniques are applied in this study. This paper proposes a fuzzy multi-criteria group decision-making (FMCGDM) method for PDSP evaluation and applies a fuzzy multi-criteria group decision support system (FMCGDSS) to support the evaluation task. We introduce a PDSP evaluation model, which has evaluation criteria within three levels, based on the characteristics of a power distribution system. A case-based example is performed on a test distribution network and demonstrates how all the problems in a PDSP evaluation are addressed using FMCGDSS. The results are acceptable to expert evaluators.

Recently, due to intrinsic characteristics in many underlying data sets, a number of probabilistic queries on uncertain data have been investigated. Top-k dominating queries are very important in many applications including decision making in a multidimensional space. In this paper, we study the problem of efficiently computing top-k dominating queries on uncertain data. We first formally define the problem. Then, we develop an efficient, threshold-based algorithm to compute the exact solution. To overcome some inherent computational deficiency in an exact computation, we develop an efficient randomized algorithm with an accuracy guarantee. Our extensive experiments demonstrate that both algorithms are quite efficient, while the randomized algorithm is quite scalable against data set sizes, object areas, k values, etc. The randomized algorithm is also highly accurate in practice.

View description>>

In twin-roll thin strip casting, the temperature of a casting roll affects the roll thermal stress, and influences the thermal deformation, the generation of roll surface cracks, the strip shape and the service life of the casting roll. In this paper, the features of the clad materials of the casting roll have been analysed, the effect of the clad thickness on the temperature field and thermal stress of casting roll has been simulated and discussed. The results show that the thick clad results in the increase of thermal resistance and then causes higher surface temperature of the clad layer, but lower temperature of copper roll sleeve. The heat expansion of the clad layer increases when the clad thickness decreases. The developed temperature model of the casting roll is helpful in optimising the design of the casting roll during twin-roll thin strip casting.

Duplicates in data streams may often be observed by the projection on a subspace and/or multiple recordings of objects. Without the uniqueness assumption on observed data elements, many conventional aggregates computation problems need to be further investigated due to their duplication-sensitive nature. In this paper, we present novel, space-efficient, one-scan algorithms to continuously maintain duplicate-insensitive order sketches so that rank-based queries can be approximately processed with a relative rank error guarantee \epsilon in the presence of data duplicates. Besides the space efficiency, the proposed algorithms are time-efficient and highly accurate. Moreover, our techniques may be immediately applied to the heavy hitter problem against distinct elements and to the existing fault-tolerant distributed communication techniques. A comprehensive performance study demonstrates that our algorithms can support real-time computation against high-speed data streams. © 2010 IEEE.

Bidens pilosa L. (commonly known as cobbler’s peg) is an annual broad leaf weed widely distributed in tropical and subtropical regions of the world and is reported to be a weed of 31 crops, including wheat. Automatic detection of Bidens in wheat farms is a non-trivial problem due to their similarity in colour and presence of occlusions. This paper proposes a methodology which could be used to discriminate Bidens from wheat to be used in operations such as autonomous weed destruction. A spectrometer is used to analyse the optical properties of Bidens and wheat leaves while achieving high classification results. However, due to the practical constraints of using spectrometers, a colour camera-based technique is proposed. It is shown that the colour-based segmentation followed by shape-based validation algorithm gives rise to high detection rates with lower false detections. We have experimentally evaluated the algorithm with Bidens detection rate of 80% and a false alarm rate of 10%. © 2010 Inderscience Enterprises Ltd.

Owing to external disturbances, parameter uncertainty, and measurement noise, it has been a challenging task to develop an appropriate controller for the automated clutch system. This paper proposes a new method for electromechanical clutch position control systems. First, a non-linear dynamic model for the screw-nut actuator associated with a clutch is derived, and then a dynamic sliding-mode controller with fuzzy adaptive tuning is developed. The fuzzy adaptive tuning arithmetic is used to improve the robustness and stability of the controller. At the same time, the chattering phenomenon is alleviated by adopting the proposed controller. Based on dSPACE and MATLAB—Simulink, the rapid control prototyping of the automated clutch is used as a method to demonstrate the efficiency and robustness of the proposed algorithm.

Clustering using the Hilbert Schmidt independence criterion (CLUHSIC) is a recent clustering algorithm that maximizes the dependence between cluster labels and data observations according to the Hilbert Schmidt independence criterion (HSIC). It is unique in that structure information on the cluster outputs can be easily utilized in the clustering process. However, while the choice of the loss function is known to be very important in supervised learning with structured outputs, we will show in this paper that CLUHSIC is implicitly using the often inappropriate zero-one loss. We propose an extension called CLUHSICAL (which stands for Clustering using HSIC and loss) which explicitly considers both the output dependency and loss function. Its optimization problem has the same form as CLUHSIC, except that its partition matrix is constructed in a different manner. Experimental results on a number of datasets with structured outputs show that CLUHSICAL often outperforms CLUHSIC in terms of both structured loss and clustering accuracy.

In this paper, we propose an iterative normalized compression method for dimensionality reduction using non-negative matrix factorization (NCMF). To factorize the instance matrix X into C×M, an objective function is defined to impose the normalization constraints to the basis matrix C and the coefficient matrix M. We argue that in many applications, instances are often normalized in one way or the other. By integrating data normalization constraints into the objective function and transposing the instance matrix, one can directly discover relations among different dimensions and devise effective and efficient procedure for matrix factorization. In the paper, we assume that feature dimensions in instance matrix are normalized, and propose an iterative solution NCMF to achieve rapid matrix factorization for dimensionality reduction. As a result, the basis matrix can be viewed as a compression matrix and the coefficient matrix becomes a mapping matrix. NCMF is simple, effective, and only needs to initialize the mapping matrix. Experimental comparisons on text, biological and image data demonstrate that NCMF gains 21.02% computational time reduction, 39.60% sparsity improvement for mapping matrix, and 8.59% clustering accuracy improvement. © 2010 Elsevier B.V.

The capacity of two minor groove binding agents that differ in their DNA sequence selectivity to modulate gene expression in human leukaemia cells was investigated. The chosen compounds were the chromomycin A3, a GC selective minor groove binder, and alkamin, an AT selective minor groove binder. As revealed by DNA microarray analysis of 6000 genes, at equitoxic doses, 5×IC 50 values for growth inhibition, the two drugs disturbed transcription, resulting in both up- and down-regulation of many hundreds of genes, 24 h after drug exposure. Direct comparisons between the most affected genes and also the cluster analysis indicated a relatively low degree of similarity between the tow expression profiles. Moreover, the ontological and the pathway responses also indicated a distinguished biological responses. Chromomycin treatment was characterized by many negative impacts on the important cellular functions and by the activation for those functions that usually take the cells towards apoptosis. In the second biological profile, the domination of many positive functions might indicate that the cells were attempting to overcome and repair the alkamin assault. Examples of these functions are positive regulation of gene expression, positive regulation of macromolecule biosynthetic processes, the cell cycle pathway and DNA repair.

High dimensional clustering algorithm based on equal or random width density grid cannot guarantee high quality clustering results in complicated data sets. In this paper, a High dimensional Clustering algorithm based on Local Significant Unit (HC_LSU) is proposed to deal with this problem, based on the kernel estimation and spatial statistical theory. Firstly, a structure, namely Local Significant Unit (LSU) is introduced by local kernel density estimation and spatial statistical test; secondly, a greedy algorithm named Greedy Algorithm for LSU (GA_LSU) is proposed to quickly find out the local significant units in the data set; and eventually, the single-linkage algorithm is run on the local significant units with the same attribute subset to generate the clustering results. Experimental results on 4 synthetic and 6 real world data sets showed that the proposed high-dimensional clustering algorithm, HC_LSU, could effectively find out high quality clustering results from the highly complicated data sets.

Iterative refinement clustering algorithms are widely used in data mining area, but they are sensitive to the initialization. In the past decades, many modified initialization methods have been proposed to reduce the influence of initialization sensitivity problem. The essence of iterative refinement clustering algorithms is the local search method. The big numbers of the local minimum points which are embedded in the search space make the local search problem hard and sensitive to the initialization. The smaller number of local minimum points, the more robust of initialization for a local search algorithm is. In this paper, we propose a TopDown Clustering algorithm with Smoothing Search Space (TDCS3) to reduce the influence of initialization. The main steps of TDCS3 are to: (1) dynamically reconstruct a series of smoothed search spaces into a hierarchical structure by `filling the local minimum points; (2) at the top level of the hierarchical structure, an existing iterative refinement clustering algorithm is run with random initialization to generate the clustering result; (3) eventually from the second level to the bottom level of the hierarchical structure, the same clustering algorithm is run with the initialization derived from the previous clustering result. Experiment results on 3 synthetic and 10 real world data sets have shown that TDCS3 has significant effects on finding better, robust clustering result and reducing the impact of initialization.

The accuracy of finite element solutions for the consolidation of porous media is influenced by the number and size of the time increments used in the analysis. A solution algorithm for adaptively selecting time increments for the solution of elastic and elastoplastic coupled consolidation problems in finite element analysis has been developed by Sloan and Abbo (1999). By treating the governing consolidation relations as a system of 1st-order differential equations their algorithm utilized subincrementation to automatically adjust the size of time increments used in the analysis. Unlike other time stepping schemes, the procedure adjusts the time increments in order to control the error due to time stepping to lie near a specified tolerance. The algorithm was shown to be robust and to provide an efficient method for the solution of consolidation problems. In this paper the efficiency of the algorithm is further demonstrated through the analysis of the construction of an embankment on a deep layer of soft soil. The time increments required for the efficient and accurate analysis of the consolidation of porous media are shown to differ by orders of magnitude. © 2010 ASCE.

The great success and high number of participants in pattern recognition related competitions last years show an important improvement of recognition and classification approaches. This success is unconceivable without the availability of huge datasets of real world data. We have invited for proposals for competitions to be held in the framework of the 12th International Conference on Frontiers in Handwriting Recognition (ICFHR2010). These competitions should aim at evaluating the performance of algorithms and methods for a particular task of Handwriting Recognition. Eight different teams composed of more than one group have submitted their proposals. The subjects of these propositions cover the field of research of handwriting recognition from pre-processing over handwritten document analysis to handwriting text/word recognition. These competitions represent an overview of current research topics and frontiers in handwriting document analysis and recognition. Only 5 competitions have received enough participants (we have defined the threshold to 3 systems) to present their evaluation at the ICFHR 2010. This paper presents the 8 competition proposals with lists of competition organizers and lists of participating systems and approaches. © 2010 IEEE.

Waterborne sanitation using flushing toilets and sewer networks has been recognised as the most important medical milestone for its transformational impact on urban public health since the 19th century (Ferriman 2007). While this model of urban sanitation has become the accepted norm for the industrialised world, its cost and resource-intensive nature is increasingly recognised as unsustainable. Several alternative models offering improved sustainability through greater material efficiency have emerged (West 2003). One of these is urine diversion (UD), the topic of this paper.

Finite Control Set Model Predictive Control has emerged as a promising control technique for Power Converters due to the fact that the inherent non-linearity of these systems can be taken into account. In addition, this strategy directly provides the switching action to be applied to the converter; consequently, additional modulation stages are not required. Despite these advantages, stability for this class of predictive control technique remains as an open problem. In the present work, we provide insights into the closed-loop stability for the Finite Control Set Model Predictive Control. As an illustrative example, we apply these stability guidelines to a Multicell Converter. ©2010 IEEE.

This paper presents a bearing-only SLAM algorithm that generates accurate and consistent maps of large environments by joining a series of small local maps. The local maps are built by least squares optimization with a proper landmark initialization technique. The local maps are then combined to build global map using Iterated Sparse Local Submap Joining Filter (I-SLSJF). The accuracy and consistency of the proposed algorithm is evaluated using simulation data sets. The algorithm is also tested using the DLR-Spatial-Cognition data set and the preprocessed Victoria Park data where the range information is ignored. The global map results are very similar to the result of full least squares optimization starting with very accurate initial values. As I-SLSJF is able to join a given set of local maps and associated uncertainties efficiently without any information loss, these results demonstrate that focusing on generating accurate local maps is a promising direction for solving large-scale bearing-only SLAM problems.

E-government (e-Gov) has become one of the most important parts of government strategies. Significant efforts have been devoted to e-Gov tourism services in many countries because tourism is one of the major profitable industries. However, the current e-Gov tourism services are limited to simple online presentation of tourism information. Intelligent e-Gov tourism services, such as the personalized e-Gov (Pe-Gov) tourism services, are highly desirable for helping users decide âwhere to go, and what to do/see❠amongst massive number of destinations and enormous attractiveness and activities. This paper proposes a framework of Pe-Gov tourism services using recommender system techniques and semantic ontology. This framework has the potential to enable tourism information seekers to locate the most interesting destinations with the most suitable activities with the least search efforts. Its workflow and some outstanding features are depicted with an example.

This paper presents a new routing discovery strategy for heterogeneous MANETs. Node heterogeneity is modeled in terms of: types and number of different interfaces, power, and transmission ranges. Our proposed route discovery algorithm is implemented on the top of On-demand Tree-based Routing Protocol (OTRP) and hence it is called OTRP Heterogeneity-Aware (OTRP_HA). OTRP_HA utilizes node heterogeneity and optimizes route discovery to reduce overheads and ensures connectivities between different types of nodes with different interfaces. Each node makes its own decision to participate in the route discovery process according to its location, local density, and available resources. Simulation results show that OTRP_HA outperforms OTRP and AODV and it reduces overheads as a number of nodes and traffic increase, while it also further prolongs the lifetime of battery-powered single-interface nodes when compared to AODV.

By improving the quality of e-government services by enabling access to services across different government agencies through one portal, services integration plays a key role in e-government development. This paper proposes a conceptual framework of ontology based e-government service integration, using Saudi Arabia's King Abdullah Scholarship Program (SAKASP) as a case study. SAKASP is a multi-domain program in which students must collect information from various Ministries to complete applications and the administering authority must verify the information supplied by the Ministries. The current implementation of SAKASP is clumsy because it is a mixture of online submission and manual collection and verification of information; its time-consuming and tedious procedures are inconvenient for the applicants and inefficient for the administrators. The proposed framework provides an integrated service by employing semantic web service (SWS) and ontology, improving the current implementation of SAKASP by automatically collecting and processing the related information for a given application. The article includes a typical scenario that demonstrates the workflow of the framework. This framework is applicable to other multi-domain e-government services.

Microarray analysis and visualization is very helpful for biologists and clinicians to understand gene expression in cells and to facilitate diagnosis and treatment of patients. However, a typical microarray dataset has thousands of features and a very small number of observations. This very high dimensional data has a massive amount of information which often contains some noise, non-useful information and small number of relevant features for disease or genotype. This paper proposes a framework for very high dimensional data reduction based on three technologies: feature selection, linear dimensionality reduction and non-linear dimensionality reduction. In this paper, feature selection based on mutual information will be proposed for filtering features and selecting the most relevant features with the minimum redundancy. A kernel linear dimensionality reduction method is also used to extract the latent variables from a high dimensional data set. In addition, a non-linear dimensionality reduction based on local linear embedding is used to reduce the dimension and visualize the data. Experimental results are presented to show the outputs of each step and the efficiency of this framework.

Recent experimental tests carried out on structural timber members have highlighted the importance of tension perpendicular to grain strength, particularly in beams with holes and notches, in connection regions, in curved beams, and in post-tensioned timber frames, Innovative engineered wood products such as Cross Banded Laminated Veneer Lumber (LVL-C) have been introduced into the market specifically to improve the perpendicular to grain properties of normal Laminated Veneer Lumber (LVL), This paper reports on tests that were performed at the University of Canterbury using specimens of sawn timber Radiata Pine, LVL and LVL-C. The perpendicular to grain tension strengths of LVL was generally lower than those for sawn timber, but the LVL-C showed a significantly improved strength. The paper also compares the experimental results with strengths predicted using both coupled elastic Finite Element Method (FEM) and Linear Elastic Fracture Mechanics (LEFM) models. These models were found to predict the average strength with reasonable accuracy.

A flexible meta modelling approach is presented to predictive control of a drying process using Adaptive Neuro-Fuzzy Inference System (ANFIS), Artificial Neural Network (ANN) and Partial Least Squares (PLS) analysis. In the proposed approach, the PLS analysis is used to pre-process actual data and to provide the necessary background to apply ANN and ANFIS approaches. A reasonable section of this study is assigned to the modelling with aim at predicting the granule particle size and executing by ANFIS and ANN. ANN hold the promise of being capable of producing non-linear models, being able to work under noise conditions and being fault tolerant to the loss of neurons or connections. Also, the ANFIS approach combines the advantages of fuzzy system and artificial neural network to design architecture and is capable of dealing with both limitation and complexity in the data set. The efficiencies of ANFIS and ANN approaches in prediction are compared and the superior approach is selected. Finally, by deploying the preferred approach, several scenarios are presented to estimate the predictive control of spray drying as an accurate, fast running and inexpensive tool. This is the first study that presents a flexible intelligent approach for predictive control of drying process by ANN, ANFIS and PLS. The approach of this study may be easily applied to other drying process. © 2010 IEEE.

Strategy Map (SM) is one of the widely used methods to create business aligned IT strategy map providing valuable insights to business executives. However, problem with strategy map method is that it is not easy to use which can lend itself to various interpretations. This is because linkages between the strategic objectives in the four strategy map perspectives are not explicit which makes SM ambiguous. Goal modelling approaches from Requirements Engineering (RE) have proven rigorous in elicitation and representation of information system requirements. In an attempt to make explicit the causal relationships of SM linkages meaningful this research proposes the use of goal modelling approach i*.

The aim of this paper is to study the human Heart Rate (HR) response during walking, cycling and rowing exercises using linear time varying (LTV) models. We used the frequency of exercise locomotion as the input to the model. This frequency characterizes the stride rate, cadence rate and strokes rate of the walking, cycling and rowing exercises respectively. The time varying parameters in the LTV models were estimated by the Kalman Filter (KF). The results in this study demonstrate that HR responses to these exercises exhibit some degree of time varying nature. © 2010 IEEE.

Our auditory perception skills enable us to selectively place one auditory channel in the center of our attention and simultaneously monitor others in the periphery of our attention. In this paper, we present and discuss two design cases that explore the design of physical interactive systems that leverage this perception skill to unobtrusively communicate relevant information. Sounds are mechanically generated by these systems, which strengthens the coupling between signification and physical interface. Both resulting designs are aimed to be used in a home environment.

Our everyday interaction in and with the physical world, has facilitated the development of auditory perception skills that enable us to selectively place one auditory channel in the center of our attention and simultaneously monitor others in the periphery. We search for ways to leverage these auditory perception skills in interactive systems. In this paper, we present three working demonstrators that use sound to subtly convey information to users in an open office. To qualitatively evaluate these demonstrators, each of them has been implemented in an office for three weeks. We have seen that such a period of time, sounds can start shifting from the center to the periphery of the attention. Furthermore, we found several issues to be addressed when designing such systems, which can inform future work in this area.

Nowadays, body area wireless sensor networks (BAWSNs) applications are increasingly being used in in-house health monitoring systems. These applications have stringent timing requirements and often run continuously without interruptions. Hence, it becomes imperative to determine the operational continuity of the BAWSN applications by measuring their availability. The BAWSN applications rely on the collection of data within a critical time from all of the source sensor nodes rather than the data from an individual source. Subsequently, the measure of availability for a BAWSN application should be based on the time and the data delivery from all the sensor nodes. Taking into account these specific characteristics and the constraints of the BAWSN, we develop a model to measure the availability of a BAWSN application based on the unavailable time. The proposed model is evaluated through a series of experiments conducted in our existing Assistive Care Loop Framework (ACLF). Furthermore, we also develop an analogous theoretical model to evaluate the availability of a BAWSN application.

While the existing spatiotemporal approaches provide an estimation of the rainfall over geographical areas, they in effect provide only for an interpolation of the data. The proposed approach introduces the concept of the construction of the likelihood function of the repartition of rain over a territory using historical storm data, both radar and land data. Radar imaging and gauges data are used to build a likelihood model for the estimation and reproduction of spatial and temporal patterns of storms over catchment areas. A novel aspect of the approach is the reduction of the two dimensioned spatial characteristics of storm rainfall fields to a univariate model representation of a storm crossing the geographical area. The study and characterization of radar tracked storms over the catchment area, along with the use of land gauges data for estimation and validation, provide for the spatiotemporal analysis of the storm rainfall, with both time and space variables being univariate. This reduction in dimensionality is a departure from traditional methods where interpolation is the major approach. It allows for the construction of a probability model to explain rainfall statistics at any location. The reproduction of rainfall data for water management studies is done through the storm models. Weather can be considered infinite in its variation, and it is doubtful that any mathematical model would accurately predict rainfall. Weather prediction and its physics are ignored and the emphasis is on the development of a statistical model. Radar imaging is used to process a large amount of information from which statistics are extracted for the construction of the likelihood model. Historical trajectories of storms are looked at as a logical explanation in time for the accumulation of rainfall levels. Along with storms strengths, they provide the essential variables for the dissection and reconstruction of the rainfall process over the catchment area. This reducti...

Within Australia, Gross Pollutant Traps (GPTs) have been installed in many stormwater drainage networks to improve the storm water quality before its discharge into receiving waters. These GPTs operate by filtering gross pollutants from the stormwater. In many GPTs these filtered pollutants are held within a wet sump until their removal. A significant fraction of the trapped litter can be classified as leaf litter. Before removal, this leaf litter may decay and hence has the potential to release nutrients into the stormwater. Therefore, nutrient management in stormwater needs to consider leaf litter decay trapped in GPTs. The decay of leaf litter stored in a GPT is discussed in the paper. Information for this discussion was obtained from a series of tests simulating the decay of leaf litter in a GPT. These tests used freshly fallen leaf litter collected from Centennial Park in Sydney, Australia. © 2010 Taylor & Francis Group, London.

Since the first edition of Australian Rainfall and Runoff (ARR) (The Institution of Engineers Australia, 1958), the aim of the publication has been to provide Australian designers and analysts with the best available information on estimating floods. Although previous editions in 1958, 1977, and 1987 have served the engineering profession well and have contributed to providing a sound basis for the design and analysis of works and structures that are subject to flood, the National Committee on Water Engineering of Engineers Australia believed that the many recent developments in the understanding of rainfall-runoff processes, the many new tools available for catchment simulation, and the rapidly expanding body of information about rainfall and runoff processes necessitated the production of a new edition. For the new edition, specific attention was made to the developing science of climate change and its impacts on the estimation of design flood flows. Therefore, the design of the revised document and the associated research activities necessary for development of the revised document specifically included provision for guidance on climate change.

Service Oriented Architecture (SOA) is a shift of paradigm in software development. It can be seen as an evolution of Component Based Software Development (CBSD), with web services used instead of Commercial Off-the-shelf (COTS) software. For the last few years the number of services on the web has increased exponentially. Among available services locating the best service that fulfills the user requirement is a challenging task for researchers. There is still no standard Requirement Engineering (RE) process defined for Service Oriented Software Development (SOSD). The traditional processes and those used for COTS selection cannot be used due to the architectural differences of SOSD with other domains. In this paper we have extracted a list of issues and challenges from literature under considerations by research community for RE process in SOSD. The issues of RE in CBSD are compared with those of SOSD, as CBSD is considered close in nature to SOSD. The results shows that there is a need of standard RE process for SOSD with proper guidance on how to perform different steps with details. © 2010 IEEE.

This FP approach uses a preprocessing phase to deal with the imbalanced data-sets problem and develops a new Fuzzy Neural Network (FNN) including an adaptive inference system in the learning algorithm along with its network structure and rule generation algorithm as a means to reduce prediction error in the FP approach.

In many mobile robotic manipulation tasks it is desirable to interact with the robots surroundings without actually grasping the object being manipulated. Non-prehensile manipulation allows a robot to interact in situations which would otherwise be impossible due to size or weight. This paper presents the derivation of a mathematical model of an object pushed by a single point and sliding in the presence of friction where the dynamic effects of mass and inertia are significant. This model is validated using numerical simulation. The derived dynamic model is also compared with a kinematic approximation from literature, showing that under certain conditions, the motion of a pushed object is similar to the motion of a non-holonomic vehicle. Finally, the results of experimental investigations are discussed and promising directions for further work are proposed.

This paper presents an adaptive-network-based fuzzy inference system (ANFIS)-fuzzy data envelopment analysis (FDEA)) for long-term natural gas (NG) consumption forecasting and analysis. Six models are proposed to forecast annual NG demand. 104 ANFIS have been constructed and tested in order to find the best ANFIS for natural gas (NG) consumption. Two parameters have been considered in construction and examination of plausible ANFIS models. Six different membership functions and several linguistic variables are considered in building ANFIS. The proposed models consist of two input variables, namely, Gross Domestic Product (GDP) and Population. All trained ANFIS are then compared with respect to mean absolute percentage error (MAPE). To meet the best performance of the intelligent based approaches, data are pre-processed (scaled) and finally our outputs are post-processed (returned to its original scale). FDEA is used to examine the behavior of gas consumption. To show the applicability and superiority of the ANFIS-FDEA approach, actual gas consumption in six Southern America countries from 1980 to 2007 is considered. The gas consumption is then forecasted up to 2015. The ANFIS-FDEA approach is capable of dealing both complexity and uncertainty as well several other unique features discussed in this paper.

Eventually the use of membranes could introduce a shift from a centralized water management to a decentralized one. The three potential new sources of water are treated wastewater or wastewater reuse, seawater and brackish water, rainwater including stormwater.

In this paper, we use Kansanen's didactic triangle to structure and analyse research on the teaching and learning of programming. Students, teachers and course content are the three entities that form the corners of the didactic triangle. The edges of the triangle represent the relationships between these three entities. We argue that many computing educators and computing education researchers operate from within narrow views of the didactic triangle. For example, computing educators often teach programming based on how they relate to the computer, and not how the students relate to the computer. We conclude that, while research that focuses on the corners of the didactic triangle is sometimes appropriate, there needs to be more research that focuses on the edges of the triangle, and more research that studies the entire didactic triangle. © 2010, Australian Computer Society, Inc.

Network protocols do not solely rely on the lower layers of the stack for security. Many of these protocols rely on a combination of layers to develop a more secure channel for data transmission. UDT, like other new next generation high speed protocols, relies on Transport, on IP, and on Network layers for data delivery and protection. However, like other existing protocols, UDT has a socket interface to link with API, a feature that makes it flexible in its implementation. This paper contends that UDT's user interface provides a means of protection by using another application service interface to cater for its security requirements. By implementing GSS-API, UDT can achieve authentication, confidentiality, and integrity during data transmission. This work provides another way of securing high speed network protocols such as UDT when implemented in various network environments.

The development of next generation protocols, such as UDT (UDP-based data transfer), promptly addressess various infrastructure requirements for transmitting data in high speed networks. However, this development creates new vulnerabilities when these protocols are designed to solely rely on existing security solutions of existing protocols such as TCP and UDP. It is clear that not all security protocols (such as TLS) can be used to protect UDT, just as security solutions devised for wired networks cannot be used to protect the wired ones. The development of UDT, similarly in the development of TCP/UDP many years ago, lacked a well-thought security architecture to address the problems that networks are presently experiencing. This paper proposed and analyses practical security mechanisms for UDT.

This paper evaluates the potential impact of hurricane damage risks to buildings due to climate change and adaptation strategies. The analysis includes a probabilistic hurricane wind field model and a hurricane vulnerability model. There is a great uncertainty on the potential change in hurricane hazard patterns due to climate change. To represent this uncertainty and to investigate the potential impact of climate change, the paper explores the scenarios of increases of -5 to 10% in mean annual maximum wind speed over 50 years. The effects of regional development dynamics, the rate of retrofit, cost of retrofit, reduction in vulnerability after retrofit, and discount rate are investigated. This risk-cost-benefit analysis is vital in indentifying optimal and cost-effective adaption strategies to the potential adverse effects of enhanced greenhouse conditions.

As a result of advances in software technology, particularly stream computing, it is now possible to implement scalable systems capable of real-time analysis of multiple physiological data streams of multiple patients. There is a growing body of evidence showing that early onset indicators of some medical conditions can be observed as subtle changes in the physiological data streams of affected patients. These real-time healthcare analytics systems can detect the early onset indicators and thus may result in earlier detection of the medical condition which may lead to earlier intervention and improved patient outcomes. Blood draws and nasal suctioning can cause changes in the values of some physiological data stream elements. Such events, sometimes referred to as physiological stream artifacts can cause the real-time analytics systems to generate false alarms since the systems assume each data element is indicative the patient's underlying physiological condition. In order to minimize the generation of false alarms, artifact events must be captured and integrated in real time with the analytics result. We present the summary of an artifact study in a tertiary neonatal intensive care unit within a children's hospital where a real-time analytics system is being piloted as part of a clinical research study. We utilize the information gathered relating to the nature of these events and propose a framework to integrate the artifact events with the analytic results in real time © 2010 ACM.

A work product is a tangible artifact used during a software development project; for example, a requirements specifications or class model diagram. Towards a general approach for evaluating and potentially improving the quality of methodologies, this paper proposes utilizing a work product-based approach to method construction known as the âwork product pool❠approach to situational method engineering to accomplish this quality improvement. Starting from the final software application and identifying work product pre-requisites by working backwards through the methodology process, work product inter-dependencies are revealed. Using method fragments from a specific methodology (here, MOBMAS), we use this backward chaining approach to effectively recreate that methodology. Evaluation of the artificially recreated methodology allows the identification of missing and/or extraneous method elements and where process steps could be improved.)

This chapter describes an integrated assessment model for city-scale urban development that links the energy used in passenger transport (public and private) and residential in-house energy use. The model divides the urban region into disjoint subregions, the core of the model being centered on residential location choice, which is calibrated by population, demographic characteristics, and building types, leading to preferences for each subregion based on household type. Submodels are subsequently used to calibrate different rates of energy in accordance with household and demographic factors.THis generates a picture of consumption patterns across the metropolitan area, enabling an appreciation of spatially heterogenous factors such as differing levels of greenhouse gas (GHG) emissions, alongside variations in the distribution of infrastructures that can create considerable variation in energy consumption between districts within cities. The energy impacts of policy decisions that affect, by way of example, where new housing is to be built and of what type, can then be simulated. The workings of the model are demonstrated in the chapter using data on Sydney, Australia, as a case study, with the research offering a policy scenario to city officials to monitor its progress towards a 2030 vision for a sustainable Sydney.

The extraction of social groups from social networks existing among employees in the company, its customers or users of various computer systems became one of the research areas of growing importance. Once we have discovered the groups, we can utilise them, in different kinds of recommender systems or in the analysis of the team structure and communication within a given population. The shortcomings of the existing methods for community discovery and lack of their applicability in multi-layered social networks were the inspiration to create a new group extraction method in complex multi-layered social networks. The main idea that stands behind this new concept is to utilise the modified version of a measure called by authors multi-layered clustering coefficient. © 2010 Springer-Verlag.

The attention towards the topic of reducing the energy expenditures has dramatically grown in recent crisis times that have forced firms to reduce them. This reduction in energy expenditures of a firm can be pursued through a wise energy procurement (we can call it “administrative energy efficiency”), thus with a reduction in the specific cost of energy (both electricity and other energy sources). But, the highest effective saving — for the whole system — would come from a direct reduction of the consumption, thus increasing the so-called “operational energy efficiency”, the unique true energy efficiency, implying the effort of the whole firm, since it requires a lower and wiser use of energy, and new and more efficient technologies. It is quite diffused the perception that governments are now taking measures to reach a common and more efficient environmental and energetic policy, but the effort is still not sufficient. The attention has obviously been paid towards the industrial sector, that covers about 30% of the consumption, second just after transportation: since now several actions have been taken to achieve the energy performance of buildings, but very few in the operations. Furthermore, it should be clear that to be really effective in this field governments should focus their attention on Small & Medium Enterprises (SMEs), usually less efficient than Large Enterprises (LEs), since SMEs represent the vast majority of the total number of industries and cover a consistent share of the energy consumption of a whole domestic industrial sector. This paper aims at providing an overview of the most effective interventions for reducing energy consumption in industrial operations that have been successfully implemented in a large number of case studies investigated in North America and Europe. The paper provides different scenarios according to the implementation of those interventions, characterized all by being Best Available Technologies and Practic...

A 12-element thin dipole uniform circular array (UCA) is studied using the Method of Moments. The effect of metallic back reflectors on the array performance, in terms of the maximum realized gain, the mutual coupling level, and the synthesized patterns, is investigated. Over the inter-element spacing range, 0.3 λ0 ≤ d ≤ 0.7λ0, simulation results show that the introduction of the cylindrical reflector achieves at least 1.0dB higher the gain than the one without using the reflector. Radial metallic 'partition walls' is proposed to be placed between axially oriented dipoles. The use of the 'partition walls' realizes further gain enhancement and H-plane mutual coupling reduction. At d = 0.4λ0 and d = 0.6λ0, maximum coupling between elements is suppressed to a level below -13dB and -20dB respectively when the height of the 'partition walls', hwall, is greater than 0.175λ0. In the synthesized realized gain pattern, mainlobe to sidelobe ratio better than 15dB and 13dB is obtained.

A frequency reconfigurable quasi-Yagi dipole antenna is presented in this paper. Simulation results show that a 35% continuously tuning impedance bandwidth, from 1.85 to 2.5GHz, is obtained. Loaded with varactor diodes, the effective electrical lengths of the driver and director dipoles are varied by changing the biasing voltages. The length adjustable director allows the endfire pattern with relatively high gain being maintained over each tuning sub-band. Across the tuning bandwidth, the predicted gain variation is from 5.8dBi to 7.9dBi. The H-plane cross-polarization level is below -17dB while this value is below -32dB in the E-plane. The front-to-back ratio is better than 12dB. © 2010 IEEE.

In capital market surveillance, an emerging trend is that a group of hidden manipulators collaborate with each other to manipulate three trading sequences: buy-orders, sell-orders and trades, through carefully arranging their prices, volumes and time, in order to mislead other investors, affect the instrument movement, and thus maximize personal benefits. If the focus is on only one of the above three sequences in attempting to analyze such hidden group based behavior, or if they are merged into one sequence as per an investor, the coupling relationships among them indicated through trading actions and their prices/volumes/times would be missing, and the resulting findings would have a high probability of mismatching the genuine fact in business. Therefore, typical sequence analysis approaches, which mainly identify patterns on a single sequence, cannot be used here. This paper addresses a novel topic, namely coupled behavior analysis in hidden groups. In particular, we propose a coupled Hidden Markov Models (HMM)-based approach to detect abnormal group-based trading behaviors. The resulting models cater for (1) multiple sequences from a group of people, (2) interactions among them, (3) sequence item properties, and (4) significant change among coupled sequences. We demonstrate our approach in detecting abnormal manipulative trading behaviors on orderbook-level stock data. The results are evaluated against alerts generated by the exchange's surveillance system from both technical and computational perspectives. It shows that the proposed coupled and adaptive HMMs outperform a standard HMM only modeling any single sequence, or the HMM combining multiple single sequences, without considering the coupling relationship. Further work on coupled behavior analysis, including coupled sequence/event analysis, hidden group analysis and behavior dynamics are very critical.

Robotic systems such as exoskeletons can be effectively used in the reduction of fatigue and musculoskeletal disorders (MSD) associated with physical tasks, but robots which work in physical contact with humans pose problems with user safety. A novel approach to developing intrinsically safe robots is to use passive actuators which have the advantage of being safer, ensuring stability, high force/weight ratios and lower power consumption. It is however not clear how effective an exoskeleton utilizing passive actuators would be in reducing fatigue and the risk of MSD. This paper analyzes the benefit of using such a system with results from dynamic simulations and an experiment using a specially designed mechanism used for evaluation. Results indicate that fatigue and effort could be reduced if robot impedance is minimized. Experiments also highlighted issues of implementing such a system into practice. ©2010 IEEE.

We present a framework to model and translate clinical rules to support complex real-time analysis of both synchronous physiological data and asynchronous clinical data. The framework is demonstrated through a case study in a neonatal intensive care context showing how a clinical rule for detecting an apnoeic event is modeled across multiple physiological data streams in the Artemis environment, which employs IBM's InfoSphere Streams middleware to support real-time stream processing. Initial clinical hypotheses for apnoea detection are modeled using UML activity diagrams which are subsequently translated into Stream's SPADE code to be deployed in Artemis to deliver real-time decision support. Our aim is to provide a Clinical Decision Support System capable of identifying and detecting patterns in physiological data streams indicative of the onset of clinically significant conditions that that may adversely affect health outcomes. Benefits associated with our approach include: 1) reduced time and effort on the clinician's part to assess health data from multiple sources; 2) the ability to allow clinicians to control the rules-engine of Artemis to enhance clinical care within their unique environments; 3) the ability to apply clinical alerts to both synchronous and asynchronous data; and 4) the ability to continuously process data in real-time. © 2010 ACM.

This paper describes the adaptation of a computational technique utilizing Extended Kohonen Maps (EKMs) and Rao-Blackwell-Kolmogorov (R-B) Filtering mechanisms for the administration of Sensor-Actuator networks (SANETs). Inspired by the BDI (Belief-Desire-Intention) Agent model from Rao and Georgeff, EKMs perform the quantitative analysis of an algorithmic artificial neural network process by using an indirect-mapping EKM to self-organize, while the Rao-Blackwell filtering mechanism reduces the external noise and interference in the problem set introduced through the self-organization process. Initial results demonstrate that a combinatorial approach to optimization with EKMs and Rao-Blackwell filtering provides an improvement in event trajectory approximation in comparison to standalone cooperative EKM processes to allow responsive event detection and optimization inpatient healthcare.

The paper describes a business reengineering process (BPR) approach to address multi-timezone (3-timezone or 3TZ) collaborative teamwork environments by combining the Holonic architecture with the Zachman Metamodel Framework. While the use of collaborative project systems is not new, the methodology to share time resources from different timezones seeks to address pedagogical and engineering process concerns in team-based project development. The benefits of collaborative project management tools go beyond a uniform platform to deploy project resources, but to also enhance systemic processes and engineering practice. This facilitates team members to dedicate their time towards common work tasks, delineates individual and shared work packages, and improves student/tutor feedback techniques as teachers can actively monitor

In the proposed work we present a combination of two paradigms: Wireless Sensor Networks (WSN) and Computer Vision applied for Motion Analysis. In this work the Computer Vision provides high-level behavioural monitoring and analysis, whereas Wireless Sensors capture detailed parameters of a moving object. Fusion of sensory information received from both types of sensors provides micro-level and macro-level details. These combined details can be used in various application areas. In considered applications, one of the areas can be Robotics. In this case this strategy can be used to monitor health of robots under certain actions and situations. Another important application domain is health care and rehabilitation of injured persons. In this application, movement of an injured body portion is measured after its treatment. Apart from the analysis of motion we also propose optimized movement advice to patients. Optimum motion advice is very useful in case of sports injury to recover strength and performance. In this paper we produce experimental work performed by simulating different movements of hands and legs in free space. The experimental simulation provides a broad range of data on motion analysis with visualization. The third area of application that is explored is elderly patient condition monitoring and motion analysis for health monitoring.

The paper aim is to explain how these fundamental properties, if imprinted on executing agents, can help in the construction of robust, cooperative and sustainable information services for infrastructure oriented software. This can occur through the application of the selected immune-computing and allometric paradigms.

A significant portion of the Hospital Information Systems currently consists of various individual legacy applications that have to be integrated, to deliver a more unified solution. The performance, reliability and other factors of these applications can alter the performance, reliability and other characteristics of integrated Solution, the Smart Hospital Management System (SHS). The actual evaluation of these parameters of these applications is outside the scope of this document. The SHS being an infrastructure component relies heavily on the actual resources made available to it for its proper functioning, operation and maintenance. This article aims to deliver an approach in architecting solutions which can be utilised as framework to address common issues in integration of enterprise level solutions. The methodologies discussed in TOGAF version 9 are utilised to demonstrate the feasibility of proposed solution. This paper introduces the problem space/scenarios, constraints, requirements, enablers, risks, sample legacy application architectures and proposed integration solution presented with TOGAF components. The growing number of waiting lists, rising pressure on medical professionals and accountability for medical negligence are only part of the motivation to take initiative towards holds a core model integration strategy in various legacy infrastructure systems.

Hypoglycemia is dangerous for Type 1 diabetes mellitus (T1DM) patients. Based on the physiological parameters, we have developed a classification unit with hybridizing the approaches of neural networks and genetic algorithm to identify the presences of hypoglycemic episodes for TIDM patients. The proposed classification unit is built and is validated by using the real T1DM patients' data sets collected from Department of Health, Government of Western Australia. Experimental results show that the proposed neural network based classification unit can achieve more accurate results on both trained and unseen T1DM patients' data sets compared with those developed based on the commonly used classification methods for medical diagnosis including statistical regression, fuzzy regression and genetic programming.

In this paper, a hybrid evolutionary algorithm (HEA) based on the approaches of the evolutionary algorithm and a local search (LS) is proposed to determine the gene signatures for predicting histologic response of chemotherapy on osteosarcoma patients, which is one of the most common malignant bone tumor in children. The HEA consists of a population of individuals but the evolution of individuals is conducted by a LS, rather than the crossover and mutation used in the traditional evolutionary algorithms. The proposed HEA can simultaneously optimize the feature subset and the classifier through a common solution coding mechanism. Experimental results indicate that HEA can obtain more accurate signatures than the other existing approaches in determining chemoresponse for osteosarcoma.

Probabilistic top-k ranking queries have been extensively studied due to the fact that data obtained can be uncertain in many real applications. A probabilistic top-k ranking query ranks objects by the interplay of score and probability, with an implicit assumption that both scores based on which objects are ranked and probabilities of the existence of the objects are stored in the same relation. We observe that in general scores and probabilities are highly possible to be stored in different relations, for example, in column-oriented DBMSs and in data warehouses. In this paper we study probabilistic top-k ranking queries when scores and probabilities are stored in different relations. We focus on reducing the join cost in probabilistic top-k ranking. We investigate two probabilistic score functions, discuss the upper/lower bounds in random access and sequential access, and provide insights on the advantages and disadvantages of random/sequential access in terms of upper/lower bounds. We also propose random, sequential, and hybrid algorithms to conduct probabilistic top-k ranking. We conducted extensive performance studies using real and synthetic datasets, and report our findings in this paper. Copyright 2010 ACM.

Dataset shift from the training data in a source domain to the data in a target domain poses a great challenge for many statistical learning methods. Most algorithms can be viewed as exploiting only the first-order statistics, namely, the empirical mean discrepancy to evaluate the distribution gap. Intuitively, considering only the empirical mean may not be statistically efficient. In this paper, we propose a non-parametric distance metric with a good property which jointly considers the empirical mean (Location) and sample covariance (Scatter) difference. More specifically, we propose an improved symmetric Stein's loss function which combines the mean and covariance discrepancy into a unified Bregman matrix divergence of which Jensen-Shannon divergence between normal distributions is a particular case. Our target is to find a good feature representation which can reduce the distribution gap between different domains, at the same time, ensure that the new derived representation can encode most discriminative components with respect to the label information. We have conducted extensive experiments on several document classification datasets to demonstrate the effectiveness of our proposed method.

This paper proposes a novel approach of suppressing narrowband interference from a multi - subband convolutional coded orthogonal frequency division multiplexing (OFDM) system. In this system, the convolutional coded data symbols using different coding generators are transmitted in different subbands. By identifying and discarding the interfered subband(s), the interference level can be greatly reduced and the system performance of the OFDM system can be improved. The interference thresholds for discarding the interfered subband(s) are determined through simulations over additive white Gaussian noise (AWGN) channel for demonstration purpose. The principle can also be applied to multipath fading channel. ©2010 IEEE.

Web photos in social media sharing websites such as Flickr are generally accompanied by rich but noisy textual descriptions (tags, captions, categories, etc.). In this paper, we proposed a tag-based photo retrieval framework to improve the retrieval performance for Flickr photos by employing a novel batch mode re-tagging method. The proposed batch mode re-tagging method can automatically refine noisy tags of a group of Flickr photos uploaded by the same user within a short period by leveraging millions of training web images and their associated rich textual descriptions. Specifically, for one group of Flickr photos, we construct a group-specific lexicon which contains only the tags of all photos within the group. For each query tag, we employ the inverted file method to automatically find loosely labeled training web images. We propose a SVM with Augmented Features, referred to as AFSVM, to learn adapted classifiers to refine the annotation tags of photos by leveraging the existing SVM classifiers of popular tags, which are associated with a large amount of positive training web images. Moreover, to further refine the annotation tags of photos in the same group, we additionally introduce an objective function that utilizes the visual similarities of photos within the group as well as the semantic proximities of their tags. Based on the refined tags, photos can be retrieved according to more reliable relevance scores. Extensive experiments demonstrate the effectiveness of our framework.

Motion blur detection and the relevant blurring parameter estimation are important for many computer vision tasks. The contribution of this paper is in two folds. First, we propose a closed-form solution for motion direction estimation on blurred image. Secondly, a novel method is proposed for motion blurred region detection. The proposed direction estimation is based on measurement of lowest directional high-frequency energy. Compared with traditional methods, it will improve accuracy with less computational cost. Moreover, the proposed motion blurred region detection can efficiently estimate blurred regions without Point Spread Function estimation. Encouraging results are shown by experiments. © 2010 IEEE.

Compressive Sensing (CS) is an emerging signal processing technique where a sparse signal is reconstructed from a small set of random projections. In the recent literature, CS techniques have demonstrated promising results for signal compression and reconstruction [9, 8, 1]. However, their potential as dimensionality reduction techniques for time series has not been significantly explored to date. To this aim, this work investigates the suitability of compressive-sensed time series in an application of human action recognition. In the paper, results from several experiments are presented: (1) in a first set of experiments, the time series are transformed into the CS domain and fed into a hidden Markov model (HMM) for action recognition; (2) in a second set of experiments, the time series are explicitly reconstructed after CS compression and then used for recognition; (3) in the third set of experiments, the time series are compressed by a hybrid CS-Haar basis prior to input into HMM; (4) in the fourth set, the time series are reconstructed from the hybrid CS-Haar basis and used for recognition. We further compare these approaches with alternative techniques such as sub-sampling and filtering. Results from our experiments show unequivocally that the application of CS does not degrade the recognition accuracy; rather, it often increases it. This proves that CS can provide a desirable form of dimensionality reduction in pattern recognition over time series.

Human action recognition can be approached by combining an action-discriminative feature set with a classifier. However, the dimensionality of typical feature sets joint with that of the time dimension often leads to a curse-of-dimensionality situation. Moreover, the measurement of the feature set is subject to sometime severe errors. This paper presents an approach to human action recognition based on robust dimensionality reduction. The observation probabilities of hidden Markov models (HMM) are modelled by mixtures of probabilistic principal components analyzers and mixtures of t-distribution sub-spaces, and compared with conventional Gaussian mixture models. Experimental results on two datasets show that dimensionality reduction helps improve the classification accuracy and that the heavier-tailed t-distribution can help reduce the impact of outliers generated by segmentation errors.

The approach adopted for design of timber concrete composite (TCC) floor systems in Australia and New Zealand is based upon extensive testing of the permitted connection types that are specified in the design procedures, identifying strength, serviceability stiffness and so called ultimate stiffness characteristic properties that are required for utilisation of the 'Gamma coefficients' method, which manipulates properties of the concrete member in order to predict the cross-section characteristics of the structure. This paper presents an overview of testing undertaken to date and the derivation of characteristic properties (5'h percentile for strength and 50'h percentile or average for stiffness).

Cervical cancer is the second most common malignancy among women worldwide, if it is detected in early stage, cure rate is relatively high. Computer aided abnormality detection for cervical smear is developed to assist medical experts to handle the microscopy images, examine cell abnormalities and diagnose dyskaryosis. The microscopy images of cells in cervix uteri are stained by the tumor marker Ki-67, so that the abnormal nuclei present brown while normal ones are bluish. Segmentation is the most important and difficult task to calculate the ratio of abnormal nuclei to all nuclei. In order to achieve accurate segmentation of nuclei, we propose a multi-level segmentation approach for abnormality identification in microscopy images. First level segmentation aims to partition abnormal (stained) nuclei regions and all nuclei regions. Because of under-segmentation after first level segmentation, second level segmentation is applied to further partition the clustered nuclei. In order to classify touching regions of clustered nuclei and separate regions of single nucleus, relevant meaningful features are extracted from regions of interest. Consequently all the nuclei regions are separated and in conjunction with the abnormal nuclei regions in the first level segmentation, the abnormality i.e. ratio of abnormal nuclei to all nuclei is obtained. Experimental results indicate that our method achieved an accuracy of 93.55% and 95.8% in term of abnormal nuclei and all nuclei respectively for identification of abnormalities. Our proposed method produces a satisfactory segmentation. © 2010 IEEE.

View description>>

In an axial-flow pump unit with conventional stator and diffuser, often considerable energy is still present in the swirl (rotation) of the liquid leaving the stator. This energy will eventually be lost from the pump system. In this experimental investigation a new design, combining the stator and diffuser together into a single component, was tested for its effectiveness in recovering this energy and thereby improving the performance of an industrysized single-stage axial-flow pump unit. Measurements of static pressure rise along the new stator-diffuser and of the swirl angle of the fluid leaving the pump unit indicate that the new design performs better than the conventional one, as a component. However, efficiency of the whole pump unit is in general slightly reduced with the new design. A number of factors were identified as contributing to this performance degradation. Most notable are the poor matching of the fluid's and vanes' angles at the component's inlet and the sudden expansion of the flow geometry at the component's outlet. It is thus expected that when these factors have been adequately addressed, the new design should improve the pump's overall performance.

This paper presents a vibration~based damage detection method that utilises frequency response functions (FRFs) to identify added mass on a two-storey framed structure. Added mass is used to simulate frequency changes due to structural damage. Artificial neural networks (ANNs) are employed to map changes in FRFs to locations of the added mass. In order to obtain suitable inputs for neural network training, principal component analysis (PCA) techniques are adopted to reduce the size of the FRF data and to filter noise. A hierarchy of neural network ensembles is used to take advantage of individual measurement characteristics from different sensors. The method is tested on laboratory and numerical models of a two-storey framed structure. From the two kinds of structures, FRF data are determined and compressed utilising PCA techniques. The PCAreduced FRFs are then used as input patterns for training and testing of ANN ensembles predicting different locations of added mass.

A key goal of adaptive multimedia delivery is to provide users with content that maximizes their quality of experience. To achieve this goal, adaptive multimedia systems require descriptions of the content and user preference information, moving beyond traditional criteria such as quality of service requirements or perceptual quality based on traditional metrics. Media is increasingly consumed within online social networks and multimedia sharing websites can also add a wealth of metadata. In this paper, mechanisms for gathering semantics that relate to user preferences when interacting with media content in social networks are proposed. Subjective results indicate the proposed mechanisms can successfully provide information about user and social group media preferences that can be used for adapting multimedia for improved user quality of experience. ©2010 IEEE.

Business Process Management (BPM) is a top priority in organisations and is rapidly proliferating as an emerging discipline in practice. However, the current studies show lack of appropriate BPM skilled professionals in the field and a dearth of opportunities to develop BPM expertise. This paper analyses the gap between available BPM-related education in Australia and required BPM capabilities. BPM courses offered by Australian universities and training institutions have been critically analysed and mapped against leading BPM capability frameworks to determine how well current BPM education and training offerings in Australia actually address the core capabilities required for BPM professionals. The outcomes reported here can be used by Australian universities and training institutions to better align and position their training materials to the BPM required capabilities. It could also be beneficial to individuals looking for a systematic and in-depth understanding of BPM capabilities and trainings. © 2010 Delavari, Bandara, Marjanovic, Mathiesen.

While the principle of fluorescence enhancement of metal nanostructures is well known, the utility of this effect in practical methodologies used in analytical laboratories remains to be established. In this work we explored the advantage of fluorescence enhancement for flow cytometry and bioimaging. We reported the observation of metal-enhanced fluorescence emission of fluorophores located on the surface of silver nanostructure-coated silica beads, suitable for flow cytometry detection. The fluorescence enhancement was investigated using a model AlexaFluor 430 IgG immunoassay. Approximately 8.5-fold higher fluorescence intensities at 430 nm excitation was observed from silvered 400 nm silica beads deposited on glass as compared to the control sample. Enhanced fluorescence signals, by a factor of 2, were also observed in imaging of cells labeled with the europium chelate, 4,4'-bis(1,1,1,2,2,3,3-heptafluoro-4,6- hexanedion-6-yl)chlorosulfo-o-terphenyl-Eu3 (BHHCT-Eu3), when such silver-coated silica beads were used as substrates. These results indicated that silver nanostructures-coated silica beads are able to provide intensified fluorescence signals for bioassays and bioimaging. © 2010 IEEE.

A key global challenge nowadays is to address climate change and reduce greenhouse gas emissions. Climate change is one of the most pressing issues facing Australia today. Improvements to energy and water efficiency of existing building stocks can significantly cut greenhouse gas emissions and reduce utility bills. With increasing recognition that green buildings outperform conventional buildings, much less known about how green building initiatives can be incorporated into upgrading existing housing stocks. In Australia due to population growth and increased in the size of dwellings coupled with the reduction of number of person per household have put an enormous pressue on energy and water consumption. Existing houses represent approximately 98% of residential building stocks 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. 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 more government financial assistance is provided.

The health service ecosystem is a sub domain of the service ecosystem, which is an ecological view of the health service domain. Due to the importance and the speciality of health services, service consumers have rigorous requirements regarding the efficiency of health service search engines. However, as most health service consumers do not have enough domain knowledge, their service queries are sometimes not able to denote their actual service requests. Moreover, we find that the existing health service search engines lack the ability to help the consumers to disambiguate their service queries, which may impede the efficiency of the search engines. In this paper, by means of semantic search technologies, we design a framework enabling user query disambiguation in the health service ecosystem. The framework embodies a health service ontology for domain knowledge-based user query disambiguation and an ECBR algorithm for accurate service retrieval. In order to evaluate the framework, we build a system prototype and perform a series of experiments on it. Conclusions from the evaluation are drawn in the paper. © 2010 IEEE.

Digital Ecosystem is an innovative high-tech environment with the purpose of supporting the activities among species within the business ecosystem. In this paper, we concern about the research issue of service retrieval within such an environment. Due to the fact that species are heterogeneous and geographically dispersed, to precisely and quickly locate a service provider becomes an issue. In addition, the Digital Ecosystem environment urgently requires the structualization of service information and a set of unified QoS measurement for service ranking and evaluation. In order to unfold the issues in detail, we use the means of case study and literature survey. Eventually we formulate the research issues in this domain and provide a possible solution. © 2010 IEEE.

View description>>

The NSW Rural Fire Service (RFS) of Australia uses canvas 'lay flat' fire hose to deliver water at an incident. A single 'rule of thumb' figure for the estimated pressure loss over a length (approx 30m) of canvas hose is used. This figure is a general average based off figures published by the hose manufacturer. These figures in turn were obtained from tests as per the Australian Standard AS-2792, which requires the hose to be under defined conditions. However, these conditions do not reproduce what is happening in a real-life fire-fighting situation. One example of the non-realistic conditions is the hose being laid completely straight. For, even in the most ideal situation, the hose still has to curve down from the back of the truck to the ground. In this experimental investigation, a test rig was set up to measure pressure loss over a length of canvas fire hose under a range of situations similar to how the hose will be laid in an actual scenario. The measured losses were found to be significantly greater than results published by the hose manufacturer, with the difference increasing with more severe bends and twists in the laid hose. The difference also varies with hose diameter. On the other hand, hose age was found to have a negligible effect on losses, contrary to expectation.

This paper explores the factors influencing an enterprises ability to generate and deploy intellectual capital in support of its strategic intent to innovate. Drawing on two research projects, we focus upon the leadership practices that enable an enterprise to innovatively leverage the intellectual capital that is potentially available to it. One project, using a phenomenological methodology, explores, at a high level, the social dynamics within twenty-five medium-sized enterprises noted for their innovative capabilities, in Sydney, Australia. The other project explores in finer detail, through an action research methodology, the transformation of stakeholder relationships within another medium-sized Sydney enterprise that has become highly innovative over the past five years. Our findings show that the most important forms of intangible capital for innovation are relationshipbased and are leveraged through stakeholder collaboration.

Many machine learning tasks can be achieved by using Multiple-instance learning (MIL) when the target features are ambiguous. As a general MIL framework, Diverse Density (DD) provides a way to learn those ambiguous features by maxmising the DD estimator, and the maximum of DD estimator is called a concept. However, modeling and finding multiple concepts is often difficult especially without prior knowledge of concept number, i.e., every positive bag may contain multiple coexistent and heterogeneous concepts but we do not know how many concepts exist. In this work, we present a new approach to find multiple concepts of DD by using an supervised mean shift algorithm. Unlike classic mean shift (an unsupervised clustering algorithm), our approach for the first time introduces the class label to feature point and each point differently contributes the mean shift iterations according to its label and position. A feature point derives from an MIL instance and takes corresponding bag label. Our supervised mean shift starts from positive points and converges to the local maxima that are close to the positive points and far away from the negative points. Experiments qualitatively indicate that our approach has better properties than other DD methods. © 2010 IEEE.

A new yoke winding for a radial magnetic bearing with permanent magnet bias flux is investigated and shown to reduce the copper loss and copper cost, by 32% in the prototype built. Magnetic circuit analysis neglecting fringing was found to give a poor estimate of the permanent magnet bias flux and 3D finite element analysis (FEA) would be needed to model it. However, 2D FEA was sufficient to model the field in the plane of the stator laminations, providing that the correct bias flux was imposed as a boundary condition. Solutions for the axial magnetic vector potential component Az were obtained, with a discontinuity prescribed across a cut from the inner to outer domain boundary. A small prototype was built and tested on a shaft whose other end was supported by a ball bearing race with free angular movement. For each of the horizontal and vertical directions, closed loop control was applied with Hall elements providing the shaft position signal. A lead-lag controller, designed using Matlab Simulink and implemented in Turbo Pascal 6, levitated the rotor.

We propose a visual event recognition framework for consumer domain videos by leveraging a large amount of loosely labeled web videos (e.g., from YouTube). First, we propose a new aligned space-time pyramid matching method to measure the distances between two video clips, where each video clip is divided into space-time volumes over multiple levels. We calculate the pair-wise distances between any two volumes and further integrate the information from different volumes with Integer-flow Earth Movers Distance (EMD) to explicitly align the volumes. Second, we propose a new cross-domain learning method in order to 1) fuse the information from multiple pyramid levels and features (i.e., space-time feature and static SIFT feature) and 2) cope with the considerable variation in feature distributions between videos from two domains (i.e., web domain and consumer domain). For each pyramid level and each type of local features, we train a set of SVM classifiers based on the combined training set from two domains using multiple base kernels of different kernel types and parameters, which are fused with equal weights to obtain an average classifier. Finally, we propose a cross-domain learning method, referred to as Adaptive Multiple Kernel Learning (A-MKL), to learn an adapted classifier based on multiple base kernels and the prelearned average classifiers by minimizing both the structural risk functional and the mismatch between data distributions from two domains. Extensive experiments demonstrate the effectiveness of our proposed framework that requires only a small number of labeled consumer videos by leveraging web data.

We construct new families of multi-error-correcting quantum codes for the amplitude damping channel. Our key observation is that, with proper encoding, two uses of the amplitude damping channel simulate a quantum erasure channel. This allows us to use concatenated codes with quantum erasure-correcting codes as outer codes for correcting multiple amplitude damping errors. Our new codes are degenerate stabilizer codes and have parameters which are better than the amplitude damping codes obtained by any previously known construction.

This paper proposes an efficient, decentralized algorithm for determining the topological relationship between two regions monitored by a geosensor network. Many centralized algorithms already exist for this purpose (used for example in spatial databases). However, these algorithms are not suited to decentralized spatial computing environments, like geosensor networks, which must operate without global knowledge of the system state and without centralized control. Unlike many existing decentralized spatial algorithms, the proposed algorithm is also able to operate in the absence of information about a node's coordinate location. This makes the algorithm suitable for applications of geosensor networks where GPS or other positioning systems are unavailable or unreliable. The algorithm approach is founded on the well-known 4-intersection model, using in-network data aggregation and spatial filtering (involving nodes only at some region boundaries). This ensures only a relatively small proportion of the network is involved in computation, thus increasing efficiency. Our analysis shows that while the overall communication complexity of the algorithm is O(n), the load balancing is optimal leading to a constant O(1) communication complexity for individual nodes. This expectation is confirmed with empirical investigation using simulation, which demonstrates the practical efficiency of the algorithm. © 2010 ACM.

Wideband frequency-domain angle-of-arrival estimation and beam forming algorithms were developed and implemented using 1 Gbps OFDM QPSK symbols. Measured performance is very close to the simulated results and experimental data for an analogue-beam-formed array.

Hybrid membrane filtration processes involve complex physical, chemical, and biological phenomena, thus their mechanistic modelling is overly challenging. In this study we use multivariate polynomials to model the fouling of an in-line flocculationâsubmerged membrane filtration system. The performance of obtained models is comparable to that of artificial neural network (ANN) models, to suit the needs of process optimisation and plant control. Their additional advantages are rapid model construction, easy presentation, inspection, and use.

There is much interest in using the virtual community as a business medium to establish a relationship between customer and stakeholders. While studies on virtual communities have widely discussed ways to sustain this community, there is the need for a complete framework or methodology to regulate members' interactions so as to produce sustainability. In order to achieve this sustainability, it is important to consider the existing trust relationship between community members and ways to identify an untrustworthy agent in a community. In this paper, we propose a framework for creating a sustainable community in Virtual Environments. The role of a third party agent and the effectiveness of continuous performance monitoring are the main keys to creating a sustainable virtual community. We also present the results of an experimental study. The study shows that the framework will help the administrator to identify all non-compliant agents after a transaction or interactions.

The nature of trust in business relationships is dynamic rather than static. Trust has evolutionary phases or a life cycle. This pattern of evolution can be described as building, maintaining and destroying. Building trust comes at high cost and hard effort. Therefore, once trust has been established in a business relationship, every effort must be made to maintain it. Maintaining trust can be defined as an effort to maximize the benefits of a relationship and to prevent the level of trust from decreasing to the destroying phase. Grounded in state-of-the-art literature, this paper presents current insights for the research into trust maintenance and suggests directions for future research in this field. © 2010 IEEE.

In this paper we consider the inter-network interference problem in Wireless Body Area Networks (WBANs). We propose a distributed inter-network interference aware power control algorithm motivated by game theory. A power control game is formulated considering both interference between nearby networks and energy efficiency of WBANs. We derive a distributed power control algorithm called ProActive Power Update (PAPU), which can efficiently find the Nash Equilibrium representing the best tradeoff between energy and network utility. A realistic power control procedure is proposed assuming limited cooperation between WBANs. We compare our algorithm with the ADP algorithm where users are punished for interfering with others and we show that our solution can utilize energy much more efficiently by only sacrificing a small amount of network utility. In addition, we show that by adjusting the energy price, PAPU provides a methodology for application scenarios where WBANs have different energy constraints and quality of service requirements. ©2010 IEEE.

The importance of estimating parameter uncertainty has been recognised in the literature with Bayesian methods being the most popular approaches for undertaking parameter uncertainty estimation. With these approaches, the parameter uncertainty is described by the posterior distribution. Application of these methods usually requires a priori knowledge about the proposal distribution of the values of the parameters. However, usually there is little a priori knowledge about the proposal distribution for the parameter values in many catchment models. Furthermore, the difficulties of exploring posterior distribution of parameter values increases as the dimensionality of the problem increases. An alternative approach is to use a GLUE methodology to develop a heuristic estimate of the parameter uncertainty. In this application of a GLUE framework, a real-value coding genetic algorithm was used to undertake an uncertainty analysis on spatially variable control parameters associated with implementation of the Storm Water Management Model (SWMM). The focus of the study was to investigate the values of spatially variable control parameters that are associated with behavioural parameter sets in a complex catchment modelling system. Of particular concern was the frequency that values within a defined range occurred. Interactions among the values of the spatially variable parameters were investigated also. Results obtained from an application of the Pearson Correlation method indicated no clear relationship between any two control parameter values. However, distinct relationships among a group of parameters were detected suggesting that the simulation performance was affected more by the combination of parameter values than by the values of the individual parameters.

The 1985 Mexico City and many other recent earthquakes clearly illustrate the importance of local soil properties on the earthquake response of structures. These earthquakes demonstrated that the rock motions could be amplified at the base of the structure. Therefore, there is a strong engineering motivation for a site-dependent dynamic response analysis for many foundations to determine the free-field earthquake motions. The determination of a realistic site-dependent free-field surface motion at the base of the structure can be the most important step in the earthquake resistant design of structures. In this study, the effects of Soil-Structure Interaction on seismic behaviour of steel moment resisting building frames have been studied using Finite Difference Method. Two types of mid-rise structures, including 5 and 15 storey buildings on a soft soil deposit have been selected and analysed under influence of three different earthquake acceleration records. The above mentioned frames been analysed under two different boundary conditions: (i) fixed-base (no soil-structure interaction), and (ii) flexible-base (considering soil-structure interaction). The results of the analyses in terms of structural forces and lateral displacements for the above mentioned boundary conditions have been compared and discussed. It is concluded that the dynamic soil-structure interaction plays a significant role in the seismic behaviour of the mentioned building frames including substantial increment in lateral inter-storey drifts of the structures and changing the performance level of the structures from life safe to near collapse or total collapse. Thus, Considering SSI effects in seismic design of steel moment resisting building frames resting on soft soil deposit is essential.

In this study, a ten storey moment resisting building frame, representing the conventional type of regular mid-rise building frames, resting on shallow foundation, is selected in conjunction with a clayey soil, representing subsoil class Ee, as classified in the AS 1170.4. The structural sections are designed after applying dynamic nonlinear time history analysis, based on both elastic method, and inelastic procedure using elastic-perfectly plastic behaviour of structural elements. The frame sections are modelled and analysed, employing Finite Difference Method using FLAC 2D software under two different boundary conditions: (i) fixed-base (no Soil-Structure Interaction), and (ii) considering Soil-Structure Interaction (SSI). Fully nonlinear dynamic analysis under influence of different earthquake records is conducted and the results of the two different cases for elastic and inelastic behaviour of the structural model are extracted and compared respectively. The results indicate that the lateral deflection increments for both cases are substantially dominating and can change the performance level of the structures from life safe to near collapse or total collapse. Therefore, conventional elastic and inelastic structural analysis methods assuming fixed-base structure may no longer be adequate to guarantee the structural safety. Therefore, considering SSI effects in seismic design of concrete moment resisting building frames resting on soft soil deposit is essential.

In this study, a fifteen storey moment resisting building frame, representing the conventional types of regular mid-rise building frames, resting on a shallow foundation, is selected in conjunction with three soil types with the shear wave velocity less that 600m/s, representing classes Ce, De and Ee, according to AS 1170.4. Characteristics of the employed soils have been extracted from the available geotechnical investigation reports of various projects. Furthermore, the structure is modelled considering the three mentioned types of the subsoil medium underneath employing the Finite Difference approach using FLAC 2D software. Three strong ground motion records adopted by the international community as benchmark earthquakes are used. These are the 1968 Hachinohe, the 1995 Kobe and the 1994 Northridge earthquakes. Fully nonlinear dynamic analysis under influence of different earthquake records is conducted, and the results of the three different cases are compared and discussed. The results indicate that the dynamic properties of the subsoil play a significant role in seismic response of the building frames under the influence of soil-structure interaction. As the shear wave velocity of the subsoil decreases, lateral deflections and inter-storey drifts of the structures increase which can change the performance level of the structures from life safe to near collapse or total collapse.

Total Maximum Daily Loads (TMDLs) identify the maximum amount of pollution that a water body can receive and still support its designated uses and allocates the maximum load to specific sources in the watershed. In the United States, The Clean Water Act requires public participation in the process of TMDL development. This requirement has been met through simple presentation of results at public meetings, strategic partnerships with key stakeholders, and/or to advisory committees in which stakeholders participate in critical decisions about TMDL definition and implementation. These decisions include model selection and assumptions, selection of water quality endpoints, load allocations, TMDL review, and implementation planning. In this article, we discuss the benefits and challenges of early and targeted engagement of stakeholders in TMDL development through a participatory modelling process based on our experience in Utah and Vermont.

Three sequential design of experiments (uniform, Latin hypercube and central composite designs) techniques are presented to deal with the optimization design problems of electromagnetic devices. These methods can be employed not only as the sampling techniques for the sequential optimization method, but also as a direct sampling optimization method. Thereafter, we use a TEAM Workshop problem to demonstrate the efficiency of the proposed methods. From the experiments and the comparison, we can see that the proposed methods can produce satisfactory solutions, and the compute cost of the total finite element analysis can be remarkably reduced. © 2010 IEEE.

Recent research has shown the effectiveness of using sparse coding(Sc) to solve many computer vision problems. Motivated by the fact that kernel trick can capture the nonlinear similarity of features, which may reduce the feature quantization error and boost the sparse coding performance, we propose Kernel Sparse Representation(KSR). KSR is essentially the sparse coding technique in a high dimensional feature space mapped by implicit mapping function. We apply KSR to both image classification and face recognition. By incorporating KSR into Spatial Pyramid Matching(SPM), we propose KSRSPM for image classification. KSRSPM can further reduce the information loss in feature quantization step compared with Spatial Pyramid Matching using Sparse Coding(ScSPM). KSRSPM can be both regarded as the generalization of Efficient Match Kernel(EMK) and an extension of ScSPM. Compared with sparse coding, KSR can learn more discriminative sparse codes for face recognition. Extensive experimental results show that KSR outperforms sparse coding and EMK, and achieves state-of-the-art performance for image classification and face recognition on publicly available datasets.

Sparse coding which encodes the original signal in a sparse signal space, has shown its state-of-the-art performance in the visual codebook generation and feature quantization process of BoW based image representation. However, in the feature quantization process of sparse coding, some similar local features may be quantized into different visual words of the codebook due to the sensitiveness of quantization. In this paper, to alleviate the impact of this problem, we propose a Laplacian sparse coding method, which will exploit the dependence among the local features. Specifically, we propose to use histogram intersection based kNN method to construct a Laplacian matrix, which can well characterize the similarity of local features. In addition, we incorporate this Laplacian matrix into the objective function of sparse coding to preserve the consistence in sparse representation of similar local features. Comprehensive experimental results show that our method achieves or outperforms existing state-of-the-art results, and exhibits excellent performance on Scene 15 data set.

Image tagging is an important technique for the image content understanding and text based image processing. Given a selection of images, how to tag these images efficiently and effectively is an interesting problem. In this paper, a novel semi-auto image tagging technique is proposed: By assigning each image a category label first, our method can automatically recommend those promising tags to each image by utilizing existing vast web data. The main contributions of our paper can be highlighted as follows: (i) By assigning each image a category label, our method can automatically recommend other tags to the image, thus reducing the human annotation efforts. Meanwhile, our method guarantee tags' diversity due to abundant web data. (ii) We use sparse coding to automatically select those semantically related images for tag propagation. (iii) Local & global ranking agglomeration will make our method robust to noisy tags. We use Event dataset as the images to be tagged, and crawled Flickr images with their associated tags according to the category label in Event dataset as the auxiliary web data. Experimental results show that our method achieves promising performance for image tagging, which proves the effectiveness of our method. © 2010 ACM.

Due to rapid technological innovation and severe competition, in hi-tech industries such as computers and communication, the upstream component price and the downstream product cost usually decline significantly with time. In such a background, an effective pricing supply chain model becomes crucial. This paper first establishes a bi-level pricing model for pricing problems for a buyer and a vendor in a supply chain. Then, a particle swarm optimization Q>SO) based algorithm is developed to solve the problem defined by this model. Experiments illustrate that this algorithm can achieve more profits for both a buyer and a vendor compared with the existing methods.

The authors have previously reported the effectiveness of using self and peer assessment to improve learning outcomes by providing opportunities to practise, assess and provide feedback on students' learning and development. Despite this work and the research of others, we observed some students felt they had nothing to learn from feedback sessions. Hence they missed the opportunity for reflection and to receive feedback to complete the learning cycle. This behaviour suggested that students needed more guidance to facilitate deeper engagement. We hypothesised that student engagement would increase if they were provided with guiding 'feedback catalyst questions' to initiate reflection and facilitate effective feedback on learning outcomes. In this paper we report testing whether this approach assisted students to gain more benefit from the self and peer assessment feedback sessions. In our investigation both students and tutors were asked to evaluate the effectiveness of the feedback catalyst questions in improving student engagement and learning. We found that the pre-feedback self reflection exercise improved learning outcomes and student engagement with more than 80% of students reporting multiple benefits. Furthermore tutors reported that the exercise assisted them to facilitate their sessions. However, not surprisingly the degree of success was related in part to the attitude of the tutor to the exercise. This suggests that while the feedback catalyst questions were extremely effective there is no substitute for enthusiastic and engaging tutorial staff. © 2010 Gardner & Willey.

Junior structural engineers rarely work alone. Their design calculations are usually peer reviewed, and they may be involved in reviewing other engineersâ designs. They are also likely to have to articulate their design decisions to their supervisor or the project team, if not the client. At the University of Technology, Sydney the authors redesigned the asssessment tasks in the subject Concrete Design to be collaborative learning-oriented tasks that provide an opportunity for students to develop and practice the skills they will need to interact with other professionals in the workplace and continue learning during their career. We theorised that allowing students to collaborate during quizzes and a project would make these activities more learning-oriented, in that students would actively learn from each other while completing their assessment. Data from various sources were collected to examine the impact of this collaborative assessment on student learning. These sources included instructor observation, analysis of student responses to a reflection activity, student surveys and student results. Students reported that not only were these activities enjoyable but they also significantly improved their learning.

A trial with a cardiac rehabilitation centre is in progress where we test a novel cardiac rehab application using a standard mobile phone and wireless sensors. The goal is to obtain insight how remote monitoring compares to conventional rehabilitation methods in terms of adherence to cardiac rehabilitation programmes. In this trial we seek feedback from patients and health professionals regarding usability and practicability of the software and hardware used and we investigate whether the use of the novel mobile rehabilitation application provides clinically meaningful reassurance to patients during their cardiac rehabilitation. The trial also investigates whether physical and psychological measures improve using the system. This paper describes the mobile cardiac rehabilitation application as well as the setup of the trial.

Abstractâ Remote ambulatory monitoring is widely seen as playing a key part in addressing the impending crisis in health care provision. We describe two mobile health solutions, one developed in the Netherlands and one in Australia. In both cases patientsâ biosignals are measured by means of body worn sensors which communicate wirelessly with a handheld device. Alarms and biosignals can be transmitted over wireless communication links to a remote location, and a remote health professional can view the biosignals via a web application. The clinical purposes are similar, however the technological approaches differ in some respects. We compare the two approaches and the experience gained working with a number of different patient groups and clinical specialties during trials in Europe and Australia.

In 2007 a major R&D project commenced in Australia, investigating the performance of timber concrete composite flooring systems for potential application in non residential buildings. In mid 2008 the scope of the project was extended with the formation of the Structural Timber Innovation Company, which is a research consortium of government, industry and the University's of Canterbury, Auckland and UTS in Sydney. The two year project has been undertaken by the University of Technology, Sydney in collaboration with the University of Canterbury, (NZ) and had focused on developing and characterising the performance of various types of timber / concrete connections. This paper describes the work undertaken in this project, including optimisation of connection geometries and presents the results of testing of over 100 connection assemblies, as well as discussing constructability issues that need to be addressed for this type of technology to gain acceptance in Australia and New Zealand and discussing current research that will continue until 2012.

At a time of high demand for engineering graduates, the mean graduation completion rate of engineering undergraduates in Australia has been identified as approximately 54% (with considerable variation across institutions and sectors). This proportion of non-completions has been viewed as an excessive loss to the qualified workforce of Australia. Broad brush, government-collected statistics do not, however, provide the level of detail required to understand who leaves, when and why they leave, and where they go. This paper reports on a pilot study undertaken to precede and inform final decisions on research design and methodology for a multi institutional project seeking to understand and reduce student attrition from engineering degrees across Australia. The aim of the project is to produce guidelines on curriculum formulation and delivery strategies to reduce attrition in engineering programs while meeting outcomes. The pilot study was conducted at an institution which has a relatively diverse range of students, a high proportion of whom study part time, and engineering degree structures incorporating traditional and internship-based degrees. Results from a cohort analysis, tracking pathways to completion or non-completion of the degree for the cohorts from two specific entry years will be presented. From this analysis, groups of students who 'persisted over long periods', 'switched to another degree' or 'withdrew from the university' were identified and interviewed. Their experiences and stories, were an essential ingredient for a better understanding of the dynamics of retention/attrition and factors which required further questioning before proceeding with the multi institutional study. © 2009 Authors.

In Australia a multi-institutional project is underway, with one of its major themes the understanding and reduction of attrition in engineering programs. The Academic Pathways for People Learning Engineering Survey (APPLES) instrument was trialled at a participating institution as a possible precursor to its application in the eight collaborating institutions. APPLES had been validated and delivered to over 4000 engineering undergraduates by the Academic Pathways Study in the US. The survey was trialled with 259 engineering students from different year levels to explore its potential to find links between students' perceptions of their motivation, skills and confidence with their goals to continue to degree completion and employment in engineering. This paper reports on the initial findings from the Australian pilot study. Matching the self reported data in the survey with statistical data has, even at this initial stage, highlighted some discrepancies and topics for further investigation. © 2010 IEEE.

At a time of high demand for engineering graduates, the mean graduation completion rate of engineering undergraduates in Australia has been identified as approximately 54% (with considerable variation across institutions and sectors). This paper reports on the initial results of cohort analyses undertaken at two engineering degree granting institutions as part of a multi institutional project seeking to understand and reduce student attrition from engineering degrees across Australia. Both institutions have a predominantly urban student population and location, but whilst one offers a conventional four year degree the other integrates two semesters of internship into its degree structure. A cohort analysis procedure, tracking pathways to completion or non-completion of the degree, applicable across diverse institutions, was piloted. Attributes such as gender, academic background, full or part time study, engineering major and student maturity were identified for each member of the cohort. The patterns revealed by these fine grained cohort analyses challenged some anecdotal perceptions and provided evidence of the inadequate nature of generalizations around attrition statistics, and the need for institutional context and culture to be considered. © 2010 Crown.

Weve been teaching engineering mechanics to first year engineering students for a long time, yet at many engineering faculties around the world there are still significant failure rates⋯ Educators have tried many different approaches to address persistent high failure rates in first year engineering mechanics courses. These approaches often involve the development of new mechanics learning resources in a variety of styles depending on the perceived learning obstacle. As part of a project funded by the Australian Learning and Teaching Council on addressing student learning diversity in engineering mechanics we have developed a framework for reviewing these existing learning resources. This framework has been used to create a database of references to resources, categorising them by attributes such as topics covered and depth of coverage, suitable student learning styles, appropriate learner levels, copyright and accessibility issues. While it is anticipated that academics will use the database to complement their normal subject delivery, it has been developed with student users as the main target audience. Student focus groups have shown that independent study can be ineffective, particularly after hours when assistance is unavailable. The aim of this database is to encourage students to be proactive in improving the quality of their learning by assisting them to select learning resources best suited to their needs, in both content and style of delivery. In this paper we describe the elements of the framework used to review engineering mechanics resources, the resultant database of resources, and the planned evaluation of its effectiveness in improving learning outcomes. The authors intend to demonstrate use of the database at the conference. © 2010 Goldfinch & Gardner.

Many hours and dollars have been spent developing new resources to improve learning outcomes in engineering mechanics courses. While many of these have been developed into packaged learning systems, available for purchase by other universities, a large proportion are available free of charge for students looking to expand their study options. Over the past eighteen months, a group of engineering academics, through Australian Learning and Teaching Council funding, has been working to develop a way of guiding students towards these online engineering mechanics learning resources. One of the outcomes of this work is an online, database-driven directory of existing online learning resources which are free for students to use in independent study. The database guides students towards resources through a range of search criteria that resources have each been evaluated on, including: Depth of topic coverage; suitable study patterns; appropriate learner level; learning styles, etc. This paper details the development, features, and intended uses of the database. It presents a plan for researching the effect that guided access to additional online learning resources has on perceptions of learning in first year engineering mechanics courses. The authors also extend an invitation to other educators to contribute to the system and promote its use to students in their classes.

Improving Indigenous access to university education has been a major focus in Australia over the last four decades. However, despite success in several areas of recognised priority to the Indigenous community, participation in Information Technology (IT) degree programs remained very low throughout the 1980s and â90s. The University of Technology, Sydney began a project to address this very issue in 2001. The Indigenous Participation in IT Project was initiated by the Faculty of Information Technology in collaboration with Indigenous Australians and members of staff of the Faculty. This project culminated in the design of a participatory IT program that has successfully seen the numbers of Indigenous students and staff in the Faculty increase. A number of factors were identified as contributing to this success. These included an improvement to recruitment processes, the building of a personalised approach to student support and the growing acceptance of the program as part of the academic culture of the faculty. Additionally, of great importance has been the development of the program as a collaboration between Indigenous staff and students and nonIndigenous staff at all levels of decision making and implementation.

A motion trajectory tracking method using a novel visual attention model and kernel density estimation is proposed in this paper. As a crucial step, moving objects detection is based on visual attention. The visual attention model is built by combination of the static and motion feature attention map and a Karhunen-Loeve transform (KLT) distribution map. Since the visual attention analysis is conducted on object level instead of pixel level, the proposed method can detect any kinds of motion objects provided saliency without the affection of objects appearance and surrounding circumstance. After locating the region of moving object, the kernel density is estimated for trajectory tracking. The experimental results show that the proposed method is promising for moving objects detection and trajectory tracking.

Small object segmentation is a challenging task in image processing and computer vision. In this paper we propose a visual attention based segmentation approach to segment interesting objects with small size in natural images. Different from traditional methods which use the single feature vectors, visual attention analysis is used on local and global features to extract the region of interesting objects. Within the region selected by visual attention analysis, Gaussian Mixture Model (GMM) is applied to further locate the object region. By incorporation of visual attention analysis into object segmentation, the proposed approach is able to narrow the searching region for object segmentation so as to increase the segmentation accuracy and reduce the computational complex. Experimental results demonstrate that the proposed approach is efficient for object segmentation in natural images, especially for small objects. The proposed method outperformeds traditional GMM based segmentation significantly

The study on high temperature superconducting (HTS) bulk magnets and their application has attracted much attention. This paper presents the performance analysis of a linear synchronous motor (LSM) with HTS bulk magnets for driving an HTS maglev vehicle model. Finite element magnetic field analysis is carried out for computing the magnetic field distribution and key parameters of the LSM, and an equivalent electrical circuit is then applied to predict the motor performance, showing that the presented motor is appropriate for driving the model vehicle. The LSM has been prototyped, installed in the maglev vehicle model, and tested for validating the theoretical analysis.

P4P (Provider Portal for Applications) integrated P2P (peer-to-peer) network is one of the main trends of P2P networks. While P4P brings advantages to P2P, it also brings new challenges in solving trust problems in P2P networks. In this paper, we consider the P4P's characteristics, domain partition and strategy matrix guidance, and propose a novel domain-based trust model for P2P networks. In our model, we distinguish peer's intra-domain behavior and inter-domain behavior. Peer's intra-domain good behavior does not mean that the peer also behaves well when interacting with other domain's peers, due to P4P's inter-domain traffic control. In addition, we give each domain a trust value, using them to modify the strategy matrix provided by P4P. Simulation results show that our model can effectively distinguish good peers and malicious peers. Even when a peer behaves well in its own domain, our method can make other domains cooperate together to evaluate the peer's bad inter-domain behavior. Lastly, using the domain's trust value to modify the P4P's strategy matrix can reduce the impact of malicious peers' cheating behavior on forming the strategy matrix. © 2010 IEEE.

This paper deals with analysis and control of the heat distribution in zone-control induction heating (ZCIH) systems. A ZCIH system consists of two or more split working coils and inverter units, which enables to control the heat and/or temperature distribution on the workpiece by adjusting the current amplitude through each working coil. This paper carries out the theoretical analysis of the generated heat in the workpiece, and reveals a relation between the coil currents and the heat distribution. As a results, it is also clarified that the heat distribution can be estimated by a simple calculation using a three-dimensional resistance matrix. The experimental results are shown to verify the validity of the developed theory by using a six-zone ZCIH laboratory setup.

Opportunistic cooperation promises to enhance the user experience when streaming media over wireless devices by improving wireless network reliability at the link level. This paper presents DAFMAC, an efficient cooperative diversity partner selection algorithm for IEEE 802.11 devices. Simulation results show DAFMAC provides a significantly higher transmission reliability in poor channel conditions than traditional ARQ techniques without modifying the device hardware. Further analysis shows the low overhead of DAFMAC makes it highly competitive with other proposed cooperative retransmission mechanisms in an ad-hoc network.

The problem of flutter and limit cycle oscillation (LCO) for two-degrees-of freedom airfoil with structural and aerodynamic nonlinearities is addressed in this paper. The model which includes freeplay in pitching is established using the Lagrange equation. The aerodynamic lift and moment are derived in terms of the 3rd-order piston theory. The forth order Runge-Kutta method is employed to solve the nonlinear dynamic equations numerically. Period response, multi-periodic response and chaotic motion are observed after investigating the phase plane and power spectral density diagrams. Bifurcation diagram of the pitching is obtained with gradually increasing values of the dimensionless air speed. The results indicate that the critical flutter speed is lower than that of the system without freeplay. It can be also concluded from the simulation that the initial value and the magnitude of the freeplay have significant effects on the dynamic motion of the system in both regions of stable and LCO. The dimensionless air speed region in which the system behaves chaotic motion is wider than that reported in the existing literature. ©2010 IEEE.

Several shrinkage compensating additives and admixtures are currently used in mortar and concrete. This study deals with the literature review and categorization of different classes of expansive additives with the objective of introducing a new range of polymeric additive. In this investigation an inorganic polymer, which is a multifunctional expansive additive, was used in different mixes of mortar. The results of experiments on drying shrinkage as well as its effect on several physical properties are reported. The new polymeric additive used in the experiments were found to decrease the amount of drying shrinkage when compared with a control mixture through the reaction of the inorganic polymer with calcium hydroxide forming a stable binder as well as an expansive agent. This new additive also proved to have a positive effect on some fresh and hardened properties of mortar.

In this paper we present results from several implementations of silicon cochleae whose dynamics are governed by the Hopf equation. These silicon cochleae exhibit the majority of active, nonlinear characteristics of the biological cochlea such as large-signal compression, two-tone suppression, the creation of distortion products and so forth. Here we explore the coupling between resonant sections of the basilar membrane to investigate phenomena such as masking and the characteristic frequency response curve of the cochlea at a particular place along the basilar membrane. We see that the interaction of resonant sections can account for these phenomena and that we can use these observations to partially explain the connectivity of the afferent and efferent fibres to the outer hair cells. This work not only gives us valuable insight into the dynamical behaviour of the early auditory system but it also highlights the benefits of building circuits of these complex systems in order to produce models whose parameters can be tuned and whose outputs can be observed and measured in real-time. ©2010 IEEE.

Greater emphasis on innovation of products and services calls for greater attention to the way organizations support collaboration in their business activities. Such support is usually provided by collaborative technologies, which must co-evolve as the collaboration evolves. This requires ways to manage changes in a way that synchronizes technical and business evolution. The paper focuses on providing a systematic approach to manage change and ensure that technologies co-evolve with changes in business requirements. The approach is two fold. One is to develop a flexible collaborative infrastructure to support collaboration. The other is to describe collaborative business processes from a number of perspectives to provide the concepts to describe change. Change is then made by applying changes to the perspectives using the concepts in an orderly sequence. The perspectives include activity, process, knowledge and social perspectives. Semantics of change and its implementation in collaborative software are then defined in terms of the perspectives.

Edge detection plays an important role in image processing area. This paper presents a Canny edge detection method based on bilateral filtering which achieves better performance than single Gaussian filtering. In this form of filtering, both spatial closeness and intensity similarity of pixels are considered in order to preserve important visual cues provided by edges and reduce the sharpness of transitions in intensity values as well. In addition, the edge detection method proposed in this paper is achieved on sampled images represented on a real hexagonal structure. Due to the compact and circular nature of the hexagonal lattice, a better quality edge map is obtained on the hexagonal structure than common edge detection on square structure. Experimental results using proposed methods exhibit also the faster speed of detection on hexagonal structure. © 2010 Springer-Verlag.

The granularity of conceptual models depends at least in part on the granularity of their underpinning metamodel. Here we investigate the theory of granularity as it can be applied to conceptual modelling and, especially, metamodelling for information systems development methodologies. With a background context of situational method engineering, this paper applies some theoretical works on granularity to the study of current metamodelling approaches. It also establishes some granularity-related best practices to take into account when adopting a metamodel, especially for its future use in developing method fragments for situational method engineering. Using these best practices will result in components of better quality and, consequently, better conceptual models and methodologies.

Deploying state-of-the-art technologies is vital and inevitable in assistive healthcare to cope with emerging services such as remote monitoring, collaborative consultation, and electronic health record. Grid computing has succeeded somewhat in enabling the sharing of resources across organizations but has not been deployed widely due to its complex implementation and interface. Cloud computing overcomes this aspect by allowing simple and easy user access, coping with users' dynamic and elastic demands, providing metered usage for its resources and hence is increasingly being adopted by individual users as well as enterprise users. The Cloud may just be the right technology for healthcare infrastructure. However, serveral serious issues concerning security, data protection and ownership, quality of services, and mobility need to be resolved before Cloud computing can be widely adopted... This paper proposes Mobile Cloud for Assistive Healthcare (MoCAsH) as an infrastructure for assistive healthcare. Besides inheriting the advantages of Cloud computing, MoCAsH embraces important concepts of mobile sensing, active sensor records, and collaborative planning by deploying intelligent mobile agents, context-aware middleware, and collaborative protocol for efficient resource sharing and planning. MoCAsH addresses security and privacy issues by deploying selective and federated P2P Cloud to protect data, preserve data ownership and strengthen aspects of security. It also addresses various quality-of-service issues concerning critical responses and energy consumption.

This paper analyses the effects of different power system devices on the dynamic transfer capability of transmission lines under varying operating conditions. An investigation on the effect of dynamics loads, wind farms and flexible AC transmission system (FACTS) devices on the transfer capability of a heavily stressed power system is carried out. A comparative study on the enhancement of transfer capability by different types of FACTS devices is also presented. The analyses have been carried out using a test system comprised of three machines and two-areas. Based on these analyses and on the simulations results shown in this paper, it is possible to conclude that the available (dynamic) transfer capability (ATC) is not only limited by the thermal and voltage constrains, but also restricted by the dynamics of different power system devices and fault conditions.

The complexity of power systems has increased in recent years due to the operation of existing transmission lines closer to their limits using flexible AC transmission system devices (FACTS), and also due to the increased penetration of new types of generators that have more intermittent characteristics and lower inertial response, such as wind generators. This changing nature of power systems has considerable effect on its dynamic behaviour resulting in power swings, dynamic interactions between different power system devices and less synchronized coupling. This paper analyses this changing nature of power systems and their dynamic behaviours to identify critical issues that limit the large-scale integration of wind generators and FACTS devices. The studies in this paper are conducted on the New England and New York power system model. Modal analysis, PV analysis, eigenvalue tracking and dynamic simulations are used to investigate the dynamic behaviour of a complex power system under both small and large disturbances. From the analyses, it can be concluded that the modes related to operating slip and shaft stiffness are critical as they may limit the large-scale integration of wind generation.

The reactive power output of compensating devices must be compared at the minimum voltage that is accepted in the grid. This paper analyses the performance of flexible AC transmission system (FACTS) devices during low-voltage recovery transients for different fault conditions. Some critical interactions amongst FACTS devices during low-voltage conditions are also investigated. The reactive power control capabilities of dynamic compensating devices at post-fault conditions are compared. In addition, this paper addresses some general concerns towards high compensations in different grid topologies. Several cases are analysed using an IEEE benchmark test system composed of 16 machines and 69 buses, which is the reduced model of New England/New York interconnection. From the analyses, it can be concluded that high compensation can reduce the security limits under certain operating conditions; certain FACTS devices are beneficial for certain network configurations; and the FACTS device with a constant current source provides better performance during low-voltage conditions.

In recent SLAM (simultaneous localization and mapping) literature, Pose Only optimization methods have become increasingly popular. This is greatly supported by the fact that these algorithms are computationally more efficient, as they focus more on the robots trajectory rather than dealing with a complex map. Implementation simplicity allows these to handle both 2D and 3D environments with ease. This paper presents a detailed evaluation on the reliability and accuracy of Pose Only SLAM, and aims at providing a definitive answer to whether optimizing poses is more advantages than optimizing features. Focus is centered around TORO, a Tree based network optimization algorithm, which has gained increased recognition within the robotics community. We compare this with Least Squares, which is often considered one of the best Maximum Likelihood method available. Results are based on both simulated and real 2D environments, and presented in a way where our conclusions can be substantiated.

This paper proposes a novel control strategy for Doubly Fed Induction Generator (DFIG) based wind power system and Permanent Magnet Synchronous Generator (PMSG) based wind power system during grid voltage dips. Based on a comparative study, the rotor over-current of DFIG and DC-link over-voltage of PMSG are identified as two main issues during grid voltage dips. A novel control strategy is proposed to enhance the wind farm Fault Ride Through (FRT) capability to some degree without additional devices, taking both grid code requirements and wind turbine requirements into account. A wind farm model consisting of DFIGs and PMSGs is built up. The effectiveness of the solution is demonstrated after simulation using MATLAB/SIMULINK.

The rate at which large variable speed wind farms are being developed had increased rapidly as the demand for green energy has grown. With this increase in distributed energy penetration into power networks, the main focus must be on power quality (Voltage Quality and Supply Reliability). However, new grid codes require wind energy generating systems to ride through grid faults, and at the same time inject reactive current into the grid. This paper presents a comprehensive survey of the control strategies for doubly-fed induction generator wind systems, including grid synchronization, maximum power point tracking (MPPT), active and reactive power regulation, and fault ride-through. From the assessment of these control techniques, conclusions about the trend of wind power generation technologies are drawn.

A novel combination of block spread orthogonal frequency division multiple access (BS-OFDMA) with space-time coded multiple input multiple output (STC MIMO) scheme is proposed for broadband wireless access uplink transmission. Using complex exponential spreading sequences, the block spreading technique can efficiently generate precoded OFDMA signal to exploit frequency diversity. An Alamouti STC MIMO encoding technique is incorporated with the block spreading to achieve further spatial diversity. The performance of the proposed STC-BS-OFDMA system using minimum mean squared error equalization is analyzed, and a closed-form asymptotical bit error rate expression is derived. Simulation results are also given to demonstrate the improved diversity performance as compared with other OFDMA schemes. The proposed techniques are well suited for future broadband wireless access systems such as 3G LTE and 4G. ©2010 IEEE.

Most people believe SLAM is a complex nonlinear stimation/optimization problem. However, recent research shows that some simple iterative methods based on linearization can sometimes provide surprisingly good solutions to SLAM without being trapped into a local minimum. This demonstrates that hidden structure exists in the SLAM problem that is yet to be understood. In this paper, we first analyze how far SLAM is from a convex optimization problem. Then we show that by properly choosing the state vector, SLAM problem can be formulated as a nonlinear least squares problem with many quadratic terms in the objective function, thus it is clearer how far SLAM is from a linear least squares problem. Furthermore, we explain that how the map joining approaches reduce the nonlinearity/nonconvexity of the SLAM problem.

The Cramér-Rao bound (CRB) has been widely used as a mean square error (MSE) lower bound for unbiased parameter estimations. For phase estimation, however, the CRB is not valid at low signal-to-noise ratio (SNR) due to the effect of phase wrapping. In this paper, closed-form approximations of the MSE lower bounds for the phase estimation are derived under both Gaussian and Rayleigh fading channels, which are particularly useful at low SNR. The derivation is based on an overlapped Gaussian distribution which is used to approximate the true posterior phase distribution. Analytical and simulation results show that the derived closed-form MSE lower bounds provide more meaningful indications to the phase estimation performance than the CRB. ©2010 IEEE.

This paper presents a joint channel and mutual coupling estimation technique for wideband antenna array to achieve high speed wireless communications in the millimetrewave frequency bands. The estimated channel frequency responses and mutual coupling matrix can be used to digitally calibrate a wideband antenna array in the frequency-domain, followed by digital beamforming. Experiments are carried out using a four-element receive array prototype in the E-band (71-76 GHz) to demonstrate the frequency-domain digital calibration and beamforming performance. The results show that both the mutual coupling and wideband effects are effectively mitigated by the proposed technique and a 11.5 dBi array gain is achieved which is very close to that of an ideal four-element antenna array. ©2010 IEEE.

View description>>

Natural-ventilation flow through a two-dimensional but realsized square room is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. The flow is induced by a solar chimney positioned on the room's roof, and it is desired to have this flow passing through the lower part of the room for ventilation purpose. The chimney in turn is in the form of a parallel channel with one plate kept at a uniform temperature that is higher than that of the ambient air (by up to 40°C), while the other plate and all of the room's walls are insulated. Eftects on ventilation flow rate and flow pattern due to a range of changing factors are invcstigated. The factors include temperature of the chimney's heated plate, length and inclination of the chimney, its location and locations of the room's other openings, and the presence of a vertical partition in the room. It is found that all these factors affect either the flow rate or flow pattern, or both. Maximum flow rate is obtained when solar chimney is in a vertical position at a roofs corner, with its heated plate on the room side. On the other hand, flow rate increases with increasing solar plate's temperature and length, as expected, but the manner of the increase varies with relative positions behYcen the chimney and room inlcts.

In contrast to the conventional analysis, the current study highlights the nonlinear characteristics of the soil during the consolidation process. A comparison of the nonlinear radial consolidation model, with the conventional theory and the equal strain theory i.e. constant volume compressibility, m v and constant coefficient of horizontal permeability, kh is presented. Finally, a case history at Muar coastal plain, Malaysia is analysed on the basis of the current solution.

Ballasted Rail tracks are widely used throughout the world due to its resiliency to the repeated wheel loads, low construction cost and ease of maintenance. However, the ballast layer needs periodic maintenance due to its deformation and degradation associated with particle breakage and fouling. A proper understanding of the contamination due to various types of fines and its implications on track drainage is a pre-requisite for effective implementation of track maintenance operations. A new parameter Void Contaminant Index (VCI) can accurately assess the contamination as it includes the effect of void ratio, specific gravity and gradation of ballast and fouling material. A series of constant head hydraulic conductivity tests using a specially designed large-scale permeability apparatus were performed on fresh ballast mixed with different proportions of fines to study the relationship between the percentage of fouling and drainage characteristics. A field trial is conducted on an instrumented track at Bulli, NSW Australia, to study the benefits of a geocomposite layer installed at the ballast-capping interface, and to evaluate the performance of recycled ballast in comparison to traditionally uniform fresh ballast. It is found that recycled ballast can be effectively reused if reinforced with a geocomposite. The geocomposite can effectively reduce vertical and lateral deformations of the ballast with obvious implications on improved track stability thereby reducing maintenance costs. © 2010 ASCE.

Plug-in Hybrid Electric Vehicles (PHEVs) are likely to be used as an alternative to conventional vehicles due to environmental friendly, energy-wise and cost effective. The effects of large-scale PHEV integration need to be investigated before they are integrated into the existing grid. This paper analyses the impact of PHEV loads on the dynamic behaviour of a power system under both small and large disturbances. From the analysis, it can be concluded that the PHEV loads can reduce the damping of the system under certain operating conditions.

Wind power, as an important and promising renewable resource, is widely studied. Because the wind is highly variable, it is very desirable to operate a wind turbine at variable speeds. In this respect, doubly fed induction generator (DFIG) has become popular in wind power generation system. The steady state simulation analysis of a DFIG is essential to understand the behavior of DFIG such that it can operate at maximum power producing point for a given wind speed. This paper explores the steady state characteristic of a DFIG in wind power generation system using MATLAB.

In photovoltaic (PV) systems, the PV array represents about 57% of the total cost of the system, so it is very desirable to operate the PV panel at the maximum power point (MPP). The output characteristics of the solar array are nonlinear and vitally affected by solar radiation, temperature, and load conditions. In this respect simulation analysis of PV array is essential to understand the output characteristics of PV array such that it can operate at the maximum power producing point for a given atmospheric condition. This paper explores the output characteristics of a PV array in MATLAB environment and the fabrication of a microcontroller based simple maximum power point tracker (MPPT). The fabricated MMPT has the capability to track the MPP and the use of the MPPT enhances the output power by 20%.

Drawing from our PD projects, this paper shows how designers enact their appreciative judgment of values by engaging in a dynamic and dialogical process of cultivating the emergence of values, developing them, and supporting their grounding. The widespread of Participatory Design (PD), have meant that different approaches and conceptualization exist in this field today. We argue that one fruitful approach is to rekindle a concern for values in PD. This requires focusing upon values as the engine that drives our activities in PD. Copyright 2010 ACM.

Wireless Mesh Network is a communication network made up of radio nodes organized in a mesh topology. It is expected that WMN to have the ability to support the new generation of streaming-media applications. We propose a time slot scheduling mechanism to provide endto- end QoS guarantee to real time flows having destination in fixed topology. Our proposed mechanism reserves a time slot for forwarding of real time flows through WMN and also at gateway. Gateway then forwards packets according to specification of real time flows in fixed topology network. This is an efficient technique that increases throughput of real time flows continue for longer period of time. Gateway and final destination receive more real time packets in the same time. When pause time increases and load of best effort traffic increases, throughput of real time packets does not affected so much by more load best effort traffic and thus quality of real time transmission is improved.

We prove that the complexity class QIP, which consists of all problems having quantum interactive proof systems, is contained in PSPACE. This containment is proved by applying a parallelized form of the matrix multiplicative weights update method to a class of semidefinite programs that captures the computational power of quantum interactive proofs. As the containment of PSPACE in QIP follows immediately from the well-known equality IP = PSPACE, the equality QIP = PSPACE follows. © 2010 ACM.

The universal use of the Internet has made it more difficult to achieve high security. Attackers target web applications instead of Telnet ports. Cyber-attacks and breaches of information security are increasing in frequency. The goal of Intrusion Detection Systems (IDSs) is to monitor network traffic and detect web-based attacks. Common IDSs are either signature based or anomaly based. Signature based IDS is unable to detect novel attack (Le., zero-day) or polymorphic attacks, until the signature database is updated. On the other hand, an anomaly-based IDS can detect new attacks and polymorphic attacks. However, anomaly based system has a relatively high number of false positives.

Intrusion detection systems are widely used security tools to detect cyber-attacks and malicious activities in computer systems and networks. Hypertext Transport Protocol (HTTP) is used for new applications without much interference. In this paper, we focus on intrusion detection of HTTP traffic by applying pattern recognition techniques using our Geometrical Structure Anomaly Detection (GSAD) model. Experimental results reveal that features extracted from HTTP request using GSAD model can be used to distinguish anomalous traffic from normal traffic, and attacks carried out over HTTP traffic can be identified. We evaluate and compare our results with the results of PAYL intrusion detection systems for the test of DARPA 1999 IDS data set. The results show GSAD has high detection rates and low false positive rates. Copyright © 2010 ACM.

Web servers and web-based applications are commonly used as attack targets. The main issues are how to prevent unauthorised access and to protect web servers from the attack. Intrusion Detection Systems (IDSs) are widely used security tools to detect cyber-attacks and malicious activities in computer systems and networks. In this paper, we focus on the detection of various web-based attacks using Geometrical Structure Anomaly Detection (GSAD) model and we also propose a novel algorithm for the selection of most discriminating features to improve the computational complexity of payload-based GSAD model. Linear Discriminant method (LDA) is used for the feature reduction and classification of the incoming network traffic. GSAD model is based on a pattern recognition technique used in image processing. It analyses the correlations between various payload features and uses Mahalanobis Distance Map (MDM) to calculate the difference between normal and abnormal network traffic. We focus on the detection of generic attacks, shell code attacks, polymorphic attacks and polymorphic blending attacks. We evaluate accuracy of GSAD model experimentally on the real-world attacks dataset created at Georgia Institute of Technology. We conducted preliminary experiments on the DARPA 99 dataset to evaluate the accuracy of feature reduction.

The ontology layer of the semantic web is now mature enough (i.e. standards like RDF, RDFs, OWL, OWL 2) and the next step is to work on a logic layer for the development of advanced reasoning capabilities for knowledge extraction and efficient decision making. Adding logic to the web means using rules to make inferences. Rules are a means of expressing business processes, policies, contracts etc but most of the studies have focused on the use of monotonic logics in layered development of the semantic web which provides no mechanism for representing or handling incomplete or contradictory information respectively. This paper discusses argumentation, semantic web and defeasible logic programming with their distinct features and identifies the different research issues that need to be addressed in order to realize defeasible argumentative reasoning in the semantic web applications. © 2010 IEEE.

In this paper we study algebraic branching programs (ABPs) with restrictions on the order and the number of reads of variables in the program. Given a permutation $\pi$ of $n$ variables, for a $\pi$-ordered ABP ($\pi$-OABP), for any directed path $p$ from source to sink, a variable can appear at most once on $p$, and the order in which variables appear on $p$ must respect $\pi$. An ABP $A$ is said to be of read $r$, if any variable appears at most $r$ times in $A$. Our main result pertains to the identity testing problem. Over any field $F$ and in the black-box model, i.e. given only query access to the polynomial, we have the following result: read $r$ $\pi$-OABP computable polynomials can be tested in $\DTIME[2^{O(r\log r \cdot \log^2 n \log\log n)}]$. Our next set of results investigates the computational limitations of OABPs. It is shown that any OABP computing the determinant or permanent requires size $\Omega(2^n/n)$ and read $\Omega(2^n/n^2)$. We give a multilinear polynomial $p$ in $2n+1$ variables over some specifically selected field $G$, such that any OABP computing $p$ must read some variable at least $2^n$ times. We show that the elementary symmetric polynomial of degree $r$ in $n$ variables can be computed by a size $O(rn)$ read $r$ OABP, but not by a read $(r-1)$ OABP, for any $0 < 2r-1 \leq n$. Finally, we give an example of a polynomial $p$ and two variables orders $\pi \neq \pi'$, such that $p$ can be computed by a read-once $\pi$-OABP, but where any $\pi'$-OABP computing $p$ must read some variable at least $2^n$

In this paper, a novel color cooccurrence histogram method, named eCCH which stands for color cooccurrence histogram at edge points, is proposed to describe the spatial-color joint distribution of images. Unlike all existing ideas, we only investigate the color distribution of pixels located at the two sides of edge points on gradient direction lines. When measuring the similarity of two eCCHs, the Gaussian weighted histogram intersection method is adopted, where both identical and similar color pairs are considered to compensate color variations. Comparative experimental results demonstrate the performance of the proposed eCCH in terms of robustness to color variance and small computational complexity. ©2010 IEEE.

Different from existing methods for segmenting degraded machine-printed characters, our algorithms are based on very weak assumptions and use no prior knowledge about the format of the plates, in order for them to be applicable to wider applications. Experimental results demonstrate promising efficiency and flexibility of the proposed scheme. © 2010 IEEE.

Strip shape is an important factor affecting the strip quality significantly during cold rolling of thin strip. In the paper, finite element simulation models of the strip shape in cold rolling for both symmetrical and asymmetrical rolling cases were successfully developed. The strip edge drop and the effect of the rolling force on the strip shape (the thickness distribution along the strip width) have been obtained. The developed finite element model has been verified with the experimental value, which shows they are in good agreement. The obtained results are applicable to control the rolled thin strip shape during cold rolling practice.

In this paper, the effects of the surface asperity wavelength, reduction and lubrication (friction) on the surface roughness transformation of the oxide scale have been studied. The simulation results show that the oxide scale surface roughness decreases with an increase of the average asperity wavelength and reduction. The initial surface roughness affects the decrease rate of surface roughness when the reduction increases. The surface roughness of the oxide scale and steel is quite close when the rolling with lubrication and both of them are reduced with reduction, and the surface roughness of the oxide scale is reduced less comparing with that of without lubrication case. The calculated roughness is close to the measured data.

Many modern wireless systems, especially some portable devices, are required operate in more than one or broad frequency bands, imposing greater challenges on the antenna design. Due to the advantages of low profile and the ease of integration with circuits, printed monopole antennas are preferred for communication systems. To extend their impedance bandwidth, several designs with different monopole shapes, such as triangular-ring [1], circular [2], rectangular [3], have been extensively studied. However, the impedance bandwidth of most monopole antennas can only cover one operating band, limiting their use in wireless communications. © 2010 IEEE.

This paper presents findings from a trial of the interactive music software Jam2Jam in a classroom music setting. Jam2Jam is software which allows musical novices to control generative music in real time. It has an interface which enables users to control multiple audio-visual parameters with a single gesture an approach intended to facilitate complex, conversational interaction. Examination of students experiences with Jam2Jam indicates that students find Jam2Jam attractive and that it has considerable potential. However, a number of issues for improvement, particularly a need for increased transparency of operation are identified. Extensions to Jam2Jam which would enable students to incorporate more of their own material into the music and visual they create during jam sessions are also proposed.

View description>>

This paper proposes an approach to modelling and visualising decision processes in large complex construction projects by incorporating a network perspective. Computer modelling and visualisation of decision processes as social and task-entity networks makes possible the identification of key participants, critical tasks, latent networks, vulnerabilities and dynamics that impact upon complex decision situations. New advances in network theory can help reveal the ways in which social, organisational, political and technological relationships shape decision outcomes. By conceiving decision processes as a complex system and modelling this system using network-theoretic principles, it is possible to include a tremendous amount of information that has remained untapped by conventional qualitative, game-theoretic, and statistical approaches. This research contributes to the understanding of the strategic implications of decision processes as complex systems of interacting actors and problem tasks, and provides the technological means for supporting them. The approach has been verified through the development of an experimental network-theoretic system.

In Wireless Sensor Networks (WSNs) one of the critical issues is the mazimization of their life time. These networks require a robust architecture that takes into account the energy consumption level of functional contituents and their interdependency. With such an architecture, the overall energy consumption can then be optimized with respects to the contstraints of an application. Unlike most current researches that focus on a single aspect of WSNs, this paper presents a Hierarchy Energy Driven Architecture (HEDA) as new architecture and a novel approach for minimising the total energy consumption of WSNs. The Energy Driven Architecture identifies generic and essential energy-consuming constituents of the network. HEDA as a constituent-based architecture is used to deploy WSNs according to energy dissipation through their contituents. This view of overall energy consumption in WSNs can be applied to optimizing and balancing energy consumption and increasing the network lifetime.

Satellite communications is the most prominent solution for covering remote areas for broadband Internet access where long and expensive cables are not feasible to be deployed. The Australia's National Broadband Network (NBN) initiation 'delivering superfast broadband to Australian homes and workplaces' currently face the problem of deploying long fibres to cover regional blackspots considering the geographic structure of the continent. Considering this we present0020some preliminary ideas to have hybrid satellite-optical broadband networks specifically covering the regional blackspots in Australia based on ring network topologies. We present topologies for the hybrid network and also architecture for the electronic (RF)-optical interface which enables to connect the fibre optical network to the satellites. Furthermore, topologies for the regional fibre optical networks in the blackspot regions are also presented in this paper. © 2010 Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.

Organizations spend substantial capital budgets on IT investment in order to achieve potential competitive advantages. However, IT investments are characterized with complexity, uncertainty, and risk. These attributes make appropriate IT investment decision making a challenging task. Decision analysis cycle methodology is a conceptual framework that facilitates achieving clarity of action in difficult decision problems. In the present study, this methodology is explained and applied on an imaging system investment of a mortgage bank to investigate how it can tackle complexity, risk and uncertainty in IT investment decisions.

In this paper, we propose a non-cooperative power control game to mitigate inter-network interference in Wireless Body Area Networks (WBANs), which use emerging short-range wireless communication technology inside, on or around the human body for healthcare, entertainment and ubiquitous computing purposes. Interference endangers the reliability of WBANs especially in critical medical applications and also leads to more power consumption in very energy-constrained WBANs. Coordinating transmission power levels, we increase the system total throughput in the presence of interference using as little power as possible. We utilize non-linear and adaptive power pricing functions to penalize high power users and increase capacity in better channels. We investigate the Nash equilibrium existence and uniqueness and propose the best response strategy in the game to reach the Nash equilibrium. ©2010 IEEE.
