This paper reports experimental tests conducted on a five-storey model using an active mass driver (AMD) system, where the control action was achieved by using a fuzzy logic controller (FLC) and the UTS state-of-the-art shake table facility. The performance of the fuzzy controller was checked against El Centro 1940, Hachinohe 1968, Northridge 1994, and Kobe 1995 earthquakes to verify the potential of using the fuzzy controller in real applications for active control of structures. Fuzzy logic is one of few mathematical model-free approaches to system identification and control. Other advantages of fuzzy logic controllers are that they can be nonlinear, adaptive, admit a high degree of parallel implementation, and tolerate uncertainty in the system. The building model under consideration is a large-scale five-storey, 3.6-m-tall, steel frame designed and manufactured at the University of Technology, Sydney. The paper details the experimental set up of the five-storey model with AMD system and the instrumentation used to measure the response, the design process of the Fuzzy Controller, and the earthquake excitations used in the experimental tests. The results of the experimental tests confirm the potential of using the adopted fuzzy controller for the active structural control using, an active mass driver (AMD) system

This paper addresses a reliability optimization problem, where the motive is to select the best components for series and series-parallel systems such that system reliability becomes maximized while simultaneously minimizing the cost, weight, and volume. Previous formulation of the problem has implicit restrictions, i.e. it either maximizes system reliability or minimizes the cost. Thus, in order to give a realistic view to the model, a comprehensive objective function has been formulated by combining the normalized values of reliability, cost, weight, and volume. In this paper, a chaos-embedded hierarchical particle swarm optimization (CE-HPSO) algorithm has been proposed to solve the problems arising in the optimization of system reliability using redundancy. The salient features of the proposed algorithm are the use of chaotic sequences and time-varying acceleration coefficients which are responsible for diversifying the search space. Moreover, to restrict the premature convergence, a hierarchical particle swarm optimizer has been used in the proposed algorithm. The performance of the CE-HPSO algorithm has been tested on three benchmark problems and the comparisons are made with genetic algorithm results. In order to check the scalability of the proposed solution methodology, small and large problems are also considered. The results demonstrate the benefits of the proposed algorithm for solving this type of problem.

Global wind-wave models such as the National Oceanic and Atmospheric Administration WaveWatch 3 (NWW3) play an important role in monitoring the world's oceans. However, untransformed data at grid points in deep water provide a poor estimate of swell characteristics at nearshore locations, which are often of significant scientific, engineering, and public interest. Explicit wave modeling, such as the Simulating Waves Nearshore (SWAN), is one method for resolving the complex wave transformations affected by bathymetry, winds, and other local factors. However, obtaining accurate bathymetry and determining parameters for such models is often difficult. When target data is available (i.e., from in situ buoys or human observers, empirical alternatives such artificial neural networks (ANNs) and linear regression may be considered for inferring nearshore conditions from offshore model output. Using a sixfold cross-validation scheme, significant wave height Hs and period were estimated at one onshore and two nearshore locations. In estimating H s at the shoreline, the validation performance of the best ANN was r = 0.91, as compared to those of linear regression (0.82), SWAN (0.78), and the NWW3 Hs baseline (0.54). © 2006 IEEE.

Remote sensing using terrestrial optical charge-coupled device cameras is a useful data collection method for geophysical measurement in the nearshore zone, where in situ measurement is difficult and time consuming. In particular, optical video sensing of the variability in human-visible surface refraction due to the nearshore incident wave field is becoming an established method for distal measurement of nearshore subtidal morphology. We report on the use of a low-mounted shore-normal camera for gathering data on cross-shore dissipative characteristics of a dynamic open beach. Data are analyzed for the purposes of classifying three of Wright and Shorts' intermediate classes of morphological beach state as determined by expert raters. Although these beach states are usually thought of as being distinctive in terms of their longshore bar variability, theory predicts that differences should also be observed in cross-shore dissipative characteristics. Three methods of generating features from statistical features from the archived optical data are described and compared in terms of their ability to discriminate between the beach states. Principal component scores of the percentile distributions were found to provide slightly better classification performance (i.e., 85%, while approximating the data using relatively fewer features), whereas classification using intensity distributions alone resulted in the worst performance, classifying 78% of beach states correctly. Class center moment profiles for each beach state were constructed, and results indicate that cross-shore wave dissipation becomes more disorganized as linear bars devolve into more complex transverse structures. © 2006 IEEE.

We show how entanglement shared between encoder and decoder can simplify the
theory of quantum error correction. The entanglement-assisted quantum codes we
describe do not require the dual-containing constraint necessary for standard
quantum error correcting codes, thus allowing us to ``quantize'' all of
classical linear coding theory. In particular, efficient modern classical codes
that attain the Shannon capacity can be made into entanglement-assisted quantum
codes attaining the hashing bound (closely related to the quantum capacity).
For systems without large amounts of shared entanglement, these codes can also
be used as catalytic codes, in which a small amount of initial entanglement
enables quantum communication.

Extant data mining is based on data-driven methodologies. It either views data mining as an autonomous data-driven, trial-and-error process or only analyzes business issues in an isolated, case-by-case manner. As a result, very often the knowledge discovered generally is not interesting to real business needs. Therefore, this article proposes a practical data mining methodology referred to as domain-driven data mining, which targets actionable knowledge discovery in a constrained environment for satisfying user preference. The domain-driven data mining consists of a DDID-PD framework that considers key components such as constraint-based context, integrating domain knowledge, human-machine cooperation, in-depth mining, actionability enhancement, and iterative refinement process. We also illustrate some examples in mining actionable correlations in Australian Stock Exchange, which show that domain-driven data mining has potential to improve further the actionability of patterns for practical use by industry and business.

The integration of Business Intelligence (BI) has been taken bybusiness decision-makers as an effective means to enhance enterprise 'soft power' and added value in the reconstruction and revolution oftraditional industries. The existing solutions based on structuralintegration are to pack together data warehouse (DW), OLAP, data mining(DM) and reporting systems from different vendors. BI system users arefinally delivered a reporting system in which reports, data models,dimensions and measures are predefined by system designers. As aresult of a survey in the US, 85% of DW projects based on the above solutions failed to meet their intended objectives. In this paper, wesummarize our investigation on the integration of BI on the basis ofsemantic integration and structural interaction. Ontology-basedintegration of BI is discussed for semantic interoperability inintegrating DW, OLAP and DM. A hybrid ontological structure isintroduced which includes conceptual view, analytical view and physicalview. These views are matched with user interfaces, DW and enterpriseinformation systems, respectively. Relevant ontological engineeringtechniques are developed for ontology namespace, semantic relationships,and ontological transformation, mapping and query in this ontologicalspace. The approach is promising for business-oriented, adaptive andautomatic integration of BI in the real world. Operational decisionmaking experiments within a telecom company have demonstrated that a BI system utilizing the proposed approach is more flexible. © 2006 - IOS Press and the authors.

If exercises are performed to increase muscle strength on one side of the body, voluntary strength can increase on the contralateral side. This effect, termed the contralateral strength training effect, is usually measured in homologous muscles. Although known for over a century, most studies have not been designed well enough to show a definitive transfer of strength that could not be explained by factors such as familiarity with the testing. However, an updated meta-analysis of 16 properly controlled studies (range 15–48 training sessions) shows that the size of the contralateral strength training effect is ∼8% of initial strength or about half the increase in strength of the trained side. This estimate is similar to results of a large, randomized controlled study of training for the elbow flexors (contralateral effect of 7% initial strength or one-quarter of the effect on the trained side). This is likely to reflect increased motoneuron output rather than muscular adaptations, although most methods are insufficiently sensitive to detect small muscle contributions. Two classes of central mechanism are identified. One involves a “spillover” to the control system for the contralateral limb, and the other involves adaptations in the control system for the trained limb that can be accessed by the untrained limb. Cortical, subcortical and spinal levels are all likely to be involved in the “transfer,” and none can be excluded with current data. Although the size of the effect is small and may not be clinically significant, study of the phenomenon provides insight into neural mechanisms associated with exercise and training.

View description>>
In this paper, the effect of reinforcing bar orientation and location on steel-concrete bond behavior is studied. The investigations are performed on two self-consolidating concretes (SCCs) and two vibrated concretes (VCs) (25 and 40 MPa [3625 and 5800 psi]). Different casting conditions are used to study the effect of the reinforcement orientation (vertical or horizontal) in relation with the casting direction and the effect of the horizontal bars' location along the height of small and tall concrete elements. In this study, the concrete casting direction is always vertical. For small-size concrete elements, SCC25 shows a better resistance against bleeding than VC25. The difference, however, is not significant for SCC40 and VC40. For samples reinforced with ribbed bars, the orientation of the bars (horizontal or vertical) has a significant and equivalent influence on both 25 MPa (3625 psi) concretes. The VC40 and SCC40 bond strength values are almost equivalent and not affected by the orientation of the bars. For tall concrete elements, voids formation under the horizontal bars was clearly observed for every type of concrete. The size of the voids was almost equivalent for SCC25, SCC40, and VC40, but significantly larger in the case of VC25, especially near the top casting surface. Finally, the maximum ultimate bond strengths obtained were approximately 20% higher for SCC than for VC, regardless of the concrete strength. Copyright © 2006, American Concrete Institute.

PurposeCollaboration is an advantageous strategy for technology‐based competition. Thus, it is of high concern to understand mechanisms behind the success of collaborations such as performance measurement system. This paper will present an empirical study conducted in the Turkish textile industry where performance measures are developed and applied.Design/methodology/approachThe paper utilizes a combination of interviews and surveys to collect data from 3T partners that are six technology supplying and ten dyeing and finishing companies. The findings indicate that besides trust, the existence of a performance measurement system is an extremely important bridge for effective supply chain collaboration (SCC). Such a system should cover metrics related to internal performance, perceptions of partners regarding the alliance performance, and the degree of inter‐firm relationship.FindingsThe paper is based on a technology partnership so the results need to be taken cautiously. However, it is clear that 3T is a successful technological partnership with six new technologies developed in two‐year period. There are some potential improvement areas, particularly in its internal activities and its relationship with the partners. The study shows that as the level of information sharing and communication among the partners increase, the performance and the benefits of the collaboration also increase.Originality/valueSCC can have long‐term goals like continuous product innovation as experienced in 3T and this might increase overall performance of an industry. That is why SCC might be particularly important tool for developin...

Knowledge of seismic active earth pressure behind rigid retaining wall is very important in the design of retaining wall in earthquake prone region. Commonly used Mononobe-Okabe method considers pseudo-static approach, which gives the linear distribution of seismic earth pressure in an approximate way. In this paper, the pseudo-dynamic method is used to compute the distribution of seismic active earth pressure on a rigid retaining wall supporting cohesionless backfill in more realistic manner by considering time and phase difference within the backfill. Planar rupture surface is considered in the analysis. Effects of a wide range of parameters like wall friction angle, soil friction angle, shear wave velocity, primary wave velocity and horizontal and vertical seismic accelerations on seismic active earth pressure have been studied. Results are provided in tabular and graphical non-dimensional form with a comparison to pseudo-static method to highlight the realistic non-linearity of seismic active earth pressures distribution. © Springer 2006.

Quality improvement is high on the agenda of Health Care Organisations (HCO) worldwide. Patient Journey Modeling is a relatively recent innovation in healthcare quality improvement that models the patient's movement through the HCO by viewing it from a patient centric perspective. Critical to the success of the redesigning care process is the involvement of all stakeholders and their commitment to actively participate in the process. Tools which promote this type of communication are a critical enabler that can significantly affect the overall process redesign outcomes. Such a tool must also be able to incorporate additional factors such as relevant policies and procedures, staff roles, system usage and measurements such as process time and cost. This paper presents a graphically based communication tool that can be used as part of the patient journey modeling process to promote stakeholder involvement, commitment and ownership as well highlighting the relationship of other relevant variables that contribute to the patient's journey. Examples of how the tool has been used and the framework employed are demonstrated via a midwife-led primary care case study. A key contribution of this research is the provision of a graphical communication framework that is simple to use, is easily understood by a diverse range of stakeholders and enables ready recognition of patient journey issues. Results include strong stakeholder buy-in and significant enhancement to the overall design of the future patient journey. Initial results indicate that the use of such a communication tool can improve the patient journey modeling process and the overall quality improvement outcomes. © 2006 IEEE.

A micropenetrometer is developed to measure structural strength inside soft soils. Different from the traditional detective technology for soil structure, the micropenetrometer is an intrusion technology to estimate the characteristics of soft soils. The work principle and main configuration of the micropenetrometer are introduced, followed by its calibration and some operation techniques. Finally, two application tests are carried out. Different soil textures such as sandy soil or clayey soil have different types of penetration curves. Through the end resistance variation, detailed description of the structural strength along penetration depth can be obtained. In addition, three-dimensional strength distribution on the vertical or transverse sections can be achieved from the penetration data evenly arranged on the grid nodes of the same surface through interpolation method. Such a technique is of significance for checking the effectiveness of soil improvement or monitoring the moisture movement in soil. Copyright © 2006 by ASTM International.

Kurzfassung
Der Begriff „Digitale Fabrik“ beschreibt den durchgängigen Einsatz von IT-Werkzeugen in allen Phasen der Produktentstehung. Insbesondere für das Aufgabenspektrum des Industrial Engineering erlangt der Einsatz digitaler Modelle, Methoden und Hilfsmittel zunehmend an Bedeutung. Die primäre Zielsetzung besteht in der Reduzierung des Planungsaufwands bei gleichzeitiger Erhöhung der Planungsqualität. Digitale Modelle sind jedoch nicht geeignet, konventionelle, materielle Modelle vollständig zu substituieren. In diesem Beitrag werden die spezifischen Einsatzmöglichkeiten sowohl materieller als auch immaterieller, digitaler Modelle diskutiert und hinsichtlich ihrer Eignung für unterschiedliche Anwendungsfälle im Industrial Engineering bewertet.

In this study, we propose three extended fitting methods to the standard ASM(active shape model). Firstly, profiles are extended from ID to 2D; Secondly, profiles of different landmarks are constructed individually; Thirdly, length of the profiles is determined adaptively with the change of level during searching, and the displacements in the last level are constrained. Each method and the combination of three methods are tested on the SJTU(Shanghai Jiaotong University) face database. In all cases, compared to the standard ASM, each method improves the accuracy or speed in a way, and the combination of three methods improves the accuracy and speed greatly.

This paper explores the ways in which Indigenous people around the world are participating in the World Wide Web, through establishing their own websites or accessing services via the Web. Indigenous websites are remarkably diverse: in addition to those representing Indigenous organizations and promoting Indigenous e-commerce, many websites have also been established to further unique concerns of Indigenous communities such as the maintenance and revitalization of Indigenous cultures, intercultural dialogue between Indigenous and non-Indigenous people, political advocacy and mobilization, community rebuilding and social support for disadvantaged communities. Despite the early involvement of Indigenous people on the Web, there still remain many unresolved issues, which include low levels of computer literacy and Internet connectivity, the cost of the technology, low levels of business understanding to support e-commerce, and concerns over the misappropriation of Indigenous knowledge and culture.

It can be claimed that Indigenous Australian cookery is the world's oldest living culinary tradition. How ancient a tradition it can be considered depends on whether one has a scientific or a spiritual worldview. Most anthropologists' estimates of when Aboriginal people first set foot in Australia vary from 45,000 to 55,000 years ago. (1) Many Indigenous Australians, on the other hand, believe that they have been in Australia from time immemorial and therefore their culinary culture also dates ab origine, 'from the beginning'. People, culture and place are inextricably intertwined and bound together as far back in the past as human memory or imagination will reach.

Abstract
In 2002 the Faculty of Information Technology at the
University of Technology Sydney began a major initiative to
improve the participation of Indigenous Australians in the
Information Technology (IT) sector. This followed an
initial study which showed that very few Indigenous
students undertook studies in IT at university and
therefore few found employment as IT professionals. As a
result of the new programme, the Faculty’s first Indigenous
staff were hired, an Indigenous resource centre was
established and the first postgraduate students recruited.
In addition, an IT tertiary preparation short course, the
Indigenous Pre-IT Program, was launched successfully, the
Faculty’s first Indigenous-specific course. With the
project, Indigenous student enrolments have increased,
mainly as part of the Pre-IT Program and as a result of
recruitment of undergraduates from amongst successful
Pre-IT Program students. However, retention of
undergraduates recruited via special admission provisions
has proved difficult despite attempts to secure
scholarships and to provide academic support. This paper
traces the development of the project and analyses the
achievements and challenges in the first three years.

Modeling and reasoning about concurrent quantum systems is very important
both for distributed quantum computing and for quantum protocol verification.
As a consequence, a general framework describing formally the communication and
concurrency in complex quantum systems is necessary. For this purpose, we
propose a model qCCS which is a natural quantum extension of classical
value-passing CCS with the input and output of quantum states, and unitary
transformations and measurements on quantum systems. The operational semantics
of qCCS is given based on probabilistic labeled transition system. This
semantics has many different features compared with the proposals in literature
in order to describe input and output of quantum systems which are possibly
correlated with other components. Based on this operational semantics, we
introduce the notions of strong probabilistic bisimilarity and weak
probabilistic bisimilarity between quantum processes and discuss some
properties of them, such as congruence under various combinators.

View description>>
The wear and wear debris from rotating-platform mobile-bearing knees and fixed-bearing knees were compared in knee joint-simulator studies. The wear rate of the fixed-bearing knees was found to increase as the kinematics were increased because of an increase in internal-external rotation and an increase in anterorposterior (AP) translation. The wear rate of the rotating-platform mobile-bearing knees was found to be significantly lower than that of the fixed-bearing knees. The rotating-platform mobile-bearing knee was able to decouple the complex kinematics to pure rotation at the inferior tibial articulating surface and linear flexion-extension and AP sliding at the superior femoral articulating interface, substantially reducing cross-shear and wear. No difference was found in the wear debris between the rotating-platform and fixed-bearing knees. This resulted in a substantially reduced functional biological activity or osteolytic potential for the rotating-platform mobile-bearing knees due to the lower wear rates.

A simple method based on the mathematical treatment of spectral absorbance profiles in conjunction with artificial neural networks (ANNs) is demonstrated for rapidly estimating chemical oxygen demand (COD) values of wastewater samples. In order to improve spectroscopic analysis and ANN training time as well as to reduce the storage space of the trained ANN algorithm, it is necessary to decrease the ANN input vector size by extracting unique characteristics from the raw input pattern. Key features from the spectral absorbance pattern were therefore selected to obtain the spectral absorbance profile, reducing the ANN input vector from 160 to 10 selected inputs. The results indicate that the COD values obtained from the selected absorbance profiles agreed well with those obtained from the entire absorbance pattern. The spectral absorbance profile technique was also compared to COD values estimated by a multiple linear regression (MLR) model to validate whether ANNs were better and more robust models for rapid COD analysis. It was found that the ANN model predicted COD values closer to standard COD values than the MLR model.

In this study, an investigation was undertaken to determine whether the predictive accuracy of an indirect, multiwavelength spectroscopic technique for rapidly determining oxygen demand (OD) values is affected by the use of unfiltered and turbid samples, as well as by the use of absorbance values measured below 200 nm. The rapid OD technique was developed that uses UV-Vis spectroscopy and artificial neural networks (ANNs) to indirectly determine chemical oxygen demand (COD) levels. It was found that the most accurate results were obtained when a spectral range of 190-350 nm was provided as data input to the ANN, and when using unfiltered samples below a turbidity range of 150 NTU. This is because high correlations of above 0.90 were obtained with the data using the standard COD method. This indicates that samples can be measured directly without the additional need for preprocessing by filtering. Samples with turbidity values higher than 150 NTU were found to produce poor correlations with the standard COD method, which made them unsuitable for accurate, real-time, on-line monitoring of OD levels. © Springer-Verlag 2006.

A permeable reactive barrier is being designed to remediate leachate from acid sulphate soils. The current research relates to testing of alkaline materials for use in the barrier, with an emphasis on waste materials. Thirteen alkaline materials including recycled concrete, limestone, calcite-bearing zeolitic breccia, blast furnace slag, lime and fly ash were tested. The batch tests involved several phases, such as leaching in deionized water to characterize the soluble components of the materials and the pH that each material could achieve. Another phase involved testing with acidic water (pH 3) to determine the acid leachable components of the materials and the pH after neutralization. The pH achieved by each reactive material was controlled by the reaction kinetics of the dominant alkaline mineral. The concretes, fly ash, and air-cooled blast furnace slag (ACBFS) all achieved a pH that is consistent with the dissolution of lime (pH 11 to 12). The limestone and zeolitic breccias all achieved a pH consistent with the dissolution of calcite (pH c. 7.4). Based on the results of the batch tests, a short-list of materials was selected that included a recycled concrete, ACBFS, three zeolitic breccias and limestone. The short-listed materials were examined for exhaustion of neutralizing ability by repeatedly replacing the acidic water and monitoring the resultant pH. The precipitates that formed during this process were analysed to characterize the chemical reactions that occurred during the tests. Based on the results, the recycled concrete was selected for testing in columns that will simulate flow conditions through the barrier. © 2006 Geological Society of London.

The design of structural frameworks for buildings is constantly evolving and is dependent on regional issues such as loading and constructability. One of the most promising recent developments for low to medium rise construction in terms of efficiency of construction, robustness and aesthetic appearance utilises concrete-filled steel tubular sections as the columns in a moment-resisting frame. These are coupled to rigid or semi-rigid connections to composite steel-concrete beams. This paper includes the results of a pilot experimental programme leading towards the development of economical, reliable connections that are easily constructed for this type of frame. The connections must provide the requisite strength, stiffness and ductility to suit gravity loading conditions as well as gravity combined with the governing lateral wind or earthquake loading. The aim is to develop connections that are stiffer, less expensive and easier to construct than those in current use. A proposed fabricated T-stub connection is to be used to connect the beam flanges and the column. These T-stubs are connected to the column using blind bolts with extensions, allowing installation from the outside of the tube. In general, the use of the extensions results in a dramatic increase in the strength and stiffness of the T-stub to column connection in tension, since the load is shared between membrane action in the tube wall and the anchorage of the bolts through the extensions into the concrete.

This paper presents an investigation into the detection and quantification of persons in real-world beach scenes for the automated monitoring of public recreation areas. Aside from the obvious use of video and digital imagery for surveillance applications, this research focuses on the analysis of images for the purpose of predicting trends in the intensity of public usage at beach sites in Australia. The proposed system uses image enhancement and segmentation techniques to detect objects in cluttered scenes. Following these steps, a newly proposed feature extraction technique is used to represent salient information in the extracted objects for training of a neural network. The neural classifier is used to distinguish the extracted objects between 'person' and 'non-person' categories to facilitate analysis of tourist activity. Encouraging results are presented for person classification on a database of real-word beach scene images.

It was found that the electrochemical charge–discharge mechanism occurring in SWNT paper electrodes is somewhere between that of carbon nanotubes (physical process) and that of metal hydride electrodes (chemical process), and consists of a charge-transfer reaction (Reduction/Oxidation)
and a diffusion step (Diffusion).

Laser Doppler vibrometry is now a well established technique enabling noncontact vibration measurements in the most challenging of environments. Rotor vibration measurements are often highlighted as a major application of laser vibrometers due to their noncontact operation and inherent immunity to shaft runout. In such measurements, resolution of the individual axial and torsional vibration components is possible via particular arrangement of the laser beam(s). Resolution of the radial or pitch/yaw vibration components, however, can only be achieved by essential post-processing of the data from simultaneous orthogonal measurements. This paper describes the principle and rigorous examination of a novel, dedicated resolution algorithm enabling, for the first time, real-time post-processing of the outputs from standard commercial instruments. The system performed well, even in the presence of noise and other typical measurement errors, and was implemented successfully in an engine vibration study.

View description>>
In a recent study [Rohde et al., quant-ph/0603130 (2006)] of several quantum
error correcting protocols designed for tolerance against qubit loss, it was
shown that these protocols have the undesirable effect of magnifying the
effects of depolarization noise. This raises the question of which general
properties of quantum error-correcting codes might explain such an apparent
trade-off between tolerance to located and unlocated error types. We extend the
counting argument behind the well-known quantum Hamming bound to derive a bound
on the weights of combinations of located and unlocated errors which are
correctable by nondegenerate quantum codes. Numerical results show that the
bound gives an excellent prediction to which combinations of unlocated and
located errors can be corrected with high probability by certain large
degenerate codes. The numerical results are explained partly by showing that
the generalized bound, like the original, is closely connected to the
information-theoretic quantity the quantum coherent information. However, we
also show that as a measure of the exact performance of quantum codes, our
generalized Hamming bound is provably far from tight.

The most notable characteristic of the heart is its movement. Detection of dynamic information describing cardiac movement such as amplitude, speed and acceleration facilitates interpretation of normal and abnormal function. In recent years, the Omni-directional M-mode Echocardiography System (OMES) has been developed as a process that builds moving information from a sequence of echocardiography image frames. OMES detects cardiac movement through construction and analysis of PositionTime Grey Waveform (PTGW) images on some feature points of the boundaries of the ventricles. Image edge detection plays an important role in determining the feature boundary points and their moving directions as the basis for extraction of PTGW imagesSpiral Architecture (SA) has proved efficient for image edge detection. SA is a hexagonal image structure in which an image is represented as a collection of hexagonal pixels. There are two operations called spiral addition and spiral multiplication defined on SA. They correspond to image translation and rotation, respectively. In this paper, we perform ventricle boundary detection based on SA using various defined chain codes. The gradient direction of each boundary point is determined at the same time. PTGW images at each boundary point are obtained through a series of spiral additions according to the directions of boundary points. Unlike the OMES system, our new approach is no longer affected by the translation movement of the heart. As its result, three curves representing the amplitude, speed and acceleration of cardiac movement can be easily drawn from the PTGW images obtained. Our approach is more efficient and accurate than OMES, and our results contain a more robust and complete description of cardiac motion.

Mantle cell lymphoma (MCL) is associated with poor clinical outcome among all the B-cell malignancies. MCL cells have a characteristic phenotype including IgM+, IgD+, CD5+, CD10−, CD19+, CD20+, Bcl2+, CD23−, CD24+, and have a (11:14) (q13:q32) translocation, involving the Bcl-1 locus and the IgH heavy chain joining region, resulting in up-regulation of Bcl-1/PRAD-1 with increased Cyclin D1 expression. In spite of our understanding of B cell development, we do not have effective therapeutic approach to treat MCL. This warrants an immediate understanding of the biology MCL cells, and key signaling pathways underlying the disease progression. Further, these key signaling pathways involved in MCL could be specifically targeted, which may have potential therapeutic value.
Emerging evidences have revealed that sonic hedgehog (Shh) signaling promotes tumor cell proliferation, and protects them from apoptosis in different cancers such as pancreatic cancer, prostate cancer, gastric cancer, medulloblastoma, basal cell carcinoma, breast cancer, etc. In addition, targeting the Shh signaling has been shown as a potential therapeutic approach to treat some of these cancers. However, the role of Shh signaling has not been reported in any of B cell malignancies including MCL. Therefore, we studied the status of Shh signaling molecules in the proliferation and survival of MCL cells in vitro using JVM-2, Granta-519, Jeko-1 and Z138 cell lines and human primary MCL cells. Our results demonstrate that the molecules involved in the Shh signaling like patched and smoothened receptors, and the target transcription factors, GLI were over expressed in Granta-519, Jeko-1, Z-138 and JVM-2 MCL cell lines, and patients primary MCL cells compared to normal human B lymphocytes. Addition of exogenous Shh increased the proliferation of JVM-2 cells in vitro. There was an increased transcripts level of GLI1, B...

The paper presents a case study for numerical analysis of the consolidation behavior of an instrumented trial embankment constructed on a soft soil foundation. Details are given to the geological profile, field instrumentation, laboratory test results, and determination of soil parameters for numerical modeling. Embankment settlement is estimated based on one-dimensional consolidation analysis and nonlinear finite-element analysis following Biot's consolidation theory. Finite-element results are calibrated against the measured field data for a period of more than 3years. Development and dissipation of excess pore pressure, long-term settlement, and horizontal displacement are predicted and discussed in light of sensitivity of embankment performance to some critical factors through a parametric study. © 2006 ASCE.

The use of native vegetation in the coastal regions of Australia has become increasingly popular for stabilising railway corridors built over expansive clays and compressive soft soils. The tree roots provide three tabilising functions: (a) they reinforce the soil; (b) they issipate excess pore pressures; and (c) they establish sufficient matric suction to increase the shear strength. The matric suction generated within the tree root zone propagates radially into the soil matrix, as a function of the moisture content change. Considering soil conditions, the type of vegetation and atmospheric conditions, a mathematical model for the rate of root water uptake is developed. A conical shape is considered to represent the geometry of the tree root zone. Based on this model for the rate of root water uptake, the pore water pressure distribution and the movement of the ground adjacent to the tree are numerically analysed. Field measurements taken from the previously published literature are compared with the authors' numerical predictions. It is found that, given the approximation of the assumed model parameters, the agreement between the predicted results and field data is still promising. The study indicates that native vegetation improves the shear strength of the soil by increasing the matric suction, and also curtails soil movements.

Le ballast et son comportement mécanique ont une influence importante sur la stabilité et la performance des voies ferrées. Nous avons étudié le comportement de détérioration et de déformation du ballast sous charge statiques et dynamiques en nous basant sur des essais triaxiaux à grande échelle. Nous avons également étudié la possibilité d'utiliser divers types de géosynthétiques pour améliorer la performance du ballast neuf et recyclé. Les résultats de cette recherche ont montré que l'adjonction de géosynthétiques améliorait la performance des voies ballastées.

The trivial equilibrium of a van der Pol-Duffing oscillator with a nonlinear feedback control may lose its stability via Hopf bifurcations, when the time delay involved in the feedback control reaches certain values. Nonresonant Hopf-Hopf interactions may occur in the controlled van der Pol-Duffing oscillator when the corresponding characteristic equation has two pairs of purely imaginary roots. With the aid of normal form theory and centre manifold theorem as well as a perturbation method, the dynamic behaviour of the nonresonant co-dimension two bifurcation is investigated by studying the possible solutions and their stability of the four-dimensional ordinary differential equations on the centre manifold. In the vicinity of the nonresonant Hopf bifurcation, the oscillator may exhibit the initial equilibrium solution, two periodic solutions as well as a quasi-periodic solution on a two-dimensional torus, depending on the dummy unfolding parameters and nonlinear terms. The analytical predictions are found to be in good agreement with the results of numerical integration of the original delay differential equation.

The trivial equilibrium of a van der Pol-Duffing oscillator under a linear-plus-nonlinear feedback control may change its stability either via a single or via a double Hopf bifurcation if the time delay involved in the feedback reaches certain values. It is found that the trivial equilibrium may lose its stability via a subcritical or supercritical Hopf bifurcation and regain its stability via a reverse suberitical or supercritical Hopf bifurcation as the time delay increases. A stable limit cycle appears after a supercritical Hopf bifurcation occurs and disappears through a reverse supercritical Hopf bifurcation. The interaction of the weakly periodic excitation and the stable bifurcating solution is investigated for the forced system under primary resonance conditions. It is shown that the forced periodic response may lose its stability via a Neimark-Sacker bifurcation. Analytical results are validated by a comparison with those of direct numerical integration.

The deformation of the thin oxide scale formed in hot metal rolling and its surface roughness characterisation are very important for the quality of the finished product. Finite element (FE) simulation of the thin oxide scale deformation and surface roughness transfer has been carried out. The authors focus on the surface asperity deformation of the thin oxide scale and strip. Surface characterisation and the mechanics of the thin oxide scale deformation are obtained from the FE simulation and experimental measurements. Simulation results are close to the measured values. The forming features of surface roughness transfer during hot metal rolling with lubrication are also discussed. (c) 2006 Elsevier B.V. All rights reserved.

Style is an ordering principle by which to structure artifacts in a design domain. The application of a visual order entails some explicit grouping property that is both cognitively plausible and contextually dependent. Central to cognitive–contextual notions are the type of representation used in analysis and the flexibility to allow semantic interpretation. We present a model of visual style based on the concept of similarity as a qualitative context-dependent categorization. The two core components of the model are semantic feature extraction and self-organizing maps (SOMs). The model proposes a method of categorizing two-dimensional unannotated design diagrams using both low-level geometric and high-level semantic features that are automatically derived from the pictorial content of the design. The operation of the initial model, called Q-SOM, is then extended to include relevance feedback (Q-SOM:RF). The extended model can be seen as a series of sequential processing stages, in which qualitative encoding and feature extraction are followed by iterative recategorization. Categorization is achieved using an unsupervised SOM, and contextual dependencies are integrated via cluster relevance determined by the observer's feedback. The following stages are presented: initial per feature detection and extraction, selection of feature sets corresponding to different spatial ontologies, unsupervised categorization of design diagrams based on appropriate feature subsets, and integration of design context via relevance feedback. From our experiments we compare different outcomes from consecutive stages of the model. The results show that the model provides a cognitively plausible and context-dependent method for characterizing visual style in design.

Architectural plans are design diagrams that describe building layout where space is planned according to design requirements. Style in architecture is generally characterized as common features appearing in a particular class of building design. This research seeks to address how to recognize architectural design style from a 2D plan diagram. We explore this question in a computational encoder-analyzer (E-A) model for 2D plans, where a characterization of 2D style is based on qualitative spatial representation and information theoretic measures. In a preliminary study of a prominent architect's plans, we demonstrate the effectiveness of our approach. We conclude by discussing practical applications of automated plan recognition and classification in design support tools.

Abstract
Blast furnace slag (BFS), a steel industrial by-product, was tested for the removal of As(III), which is a highly toxic, mobile and predominant species in anoxic groundwater. Batch adsorption experiments were performed to determine the feasibility of BFS as an adsorbent for removing As(III) from groundwater as As(III) concentration and the pH of water were varied. The maximum As(III) adsorption capacity by BFS was 1.40 mg As(III)/g of BFS at 1 mg/L As(III) initial concentration, at 25°C, which was calculated using the Langmuir isotherm. The homogeneous surface diffusion model (HSDM) was successfully applied to predict the sorptive removal of As(III) onto the BFS. Kinetic studies indicated that the film diffusion as well as surface diffusion of As in the BFS was involved. It was found that the film diffusion coefficient (kf) was 5.27 × 10-5 to 4.06 × 10-6 m/s and surface diffusion coefficient (Ds) was 2.31 × 10-14 to 7.13 × 10-14 m2/s for the initial As(III) concentrations of 0.1 to 100 mg/L. Oxidation of As(III) to As(V) and its adsorption/precipitation onto BFS is involved during the As(III) removal mechanism. It was also found that H4SiO40, PO43-, NO3-, SO42- and HCO3- are potential interferences in the As(III) adsorption reaction. Results suggest that 99.9% As(III) at 1 mg/L can be removed by 10 g/L BFS, which can be used as a permeable reactive barrier (PRB) material to remove As(III) from groundwater. Details of As(III) adsorption and coprecipitation systems and interferences of As(III) molecular interactions were also studied.

This paper describes the use of experiential learning theory in the development of an undergraduate subject in collaborative systems. The purpose of the subject was to introduce students to the design, development and use of collaborative systems in organizational environments. Early in the subject’s development it was decided that in order for students to gain a deeper understanding of the issues involved in the development of collaborative systems, they should collaborate using an e-learning system so that they could experience these problems first hand. The paper provides an overview of the subject structure, the views of students with regard to the learning approach and some of the outcomes that were observed. The findings revealed that the experiential approach was successful in providing students with a good understanding of the issues associated with the design and use of collaborative systems. However, while many achieved deeper learning outcomes than would normally be provided by a traditional didactic approach, there were students who failed to achieve the desired learning levels. The findings not only provide support for Perry’s model of intellectual development and the value of setting unstructured problems, but also demonstrate the need for structure in early experiential events to which students are exposed.

This letter focuses on the performance analysis of the decorrelating receiver in multipath Rician faded CDMA channels. M-ary QAM scheme is employed to improve the spectral efficiency. Approximate expressions are first derived for the two performance indexes: the average symbol error rate (SER) and the average bit error rate (BER) when the decorrelating-first receiver perfectly knows the channel information of the user of interest. To achieve desirable closed-form expressions of the SER and the BER, we exploit results in large system analysis and make assumptions of a high signal-to-interference ratio (SIR) and/or a small Rician K-factor. To measure the receiver performance in the practical scenario, we further derive expressions to approximate the average SER and BER of the decorrelating-first scheme with channel uncertainty. Simulation results demonstrate that the analytical results can also be employed to evaluate the performance of the combining-first receiver. © 2006 IEEE.

The number of road accident related fatalities and damages are reduced substantially by improving road infrastructure and enacting and imposing laws. Further reduction is possible through embedding intelligence onto the vehicles for safe decision making. Road boundary information plays a major role in developing such intelligent vehicles. A prominent feature of roads in urban, semi-urban, and similar environments, is curbs on either side defining the road's boundary. In this brief, a novel methodology of tracking curbs is proposed. The problem of tracking a curb from a moving vehicle is formulated as tracking of a maneuvering target in clutter from a mobile platform using onboard sensors. A curb segment is presumed to be the maneuvering target, and is modeled as a nonlinear Markov switching process. The target's (curb's) orientation and location measurements are simultaneously obtained using a two-dimensional (2-D) scanning laser radar (LADAR) and a charge-coupled device (CCD) monocular camera, and are modeled as traditional base state observations. Camera images are also used to estimate the target's mode, which is modeled as a discrete-time point process. An effective curb tracking algorithm, known as Curb Tracking and Estimation (CuTE) using multiple modal sensor information is, thus, synthesized in an image enhanced interactive multiple model filtering framework. The use and fusion of camera vision and LADAR within this frame provide for efficient, effective, and robust tracking of curbs. Extensive experiments conducted in a campus road network demonstrate the viability, effectiveness, and robustness of the proposed method

This paper describes and enacts a process for bootstrapping a more systematic discussion of computing education within a school of computing at a researchintensive Australasian university. Thus far, the project has gone through three stages. In the first stage, some academics were interviewed about their approach to teaching. In the second stage, selected anonymous quotes from the interviews were presented and discussed by other interested members of the school at workshops. In the final stage, selected anonymous quotes from the interviews and workshops were placed on a web-based survey, to which interested members of the school responded. These forms of data will be used to drive further stages of debate within the school. The theoretical underpinnings of this project are Wenger's concept of a community of practice, phenomenography, and socially constructivism. The aim is not to instruct the academics in any 'right way' to teach. Instead, the aim is to facilitate debate, where the teachers identify the problems, and in finding the solutions they construct their own 'pedagogic reality'. As facilitators of this process, the authors of this paper highlighted dialectically opposed views in quotes from the teachers, and then allow the teachers to synthesise those views into a more sophisticated view. Our ultimate project aim is to grow a teaching community that balances reified theories of teaching and learning with participation in a community of practice. © 2006, Australian Computer Society, Inc.

Non-linear hysteresis is a complicated phenomenon associated with magnetorheological (MR) fluid dampers. A new model for MR dampers is proposed in this paper. For this, computationally-tractable algebraic expressions are suggested here in contrast to the commonly-used BoucWen model, which involves internal dynamics represented by a non-linear differential equation. In addition, the model parameters can be explicitly related to the hysteretic phenomenon. To identify the model parameters, a particle swarm optimization (PSO) algorithm is employed using experimental forcevelocity data obtained from various operating conditions. In our algorithm, it is possible to relax the need for a priori knowledge on the parameters and to reduce the algorithmic complexity. Here, the PSO algorithm is enhanced by introducing a termination criterion, based on the statistical hypothesis testing to guarantee a user-specified confidence level in stopping the algorithm. Parameter identification results are included to demonstrate the accuracy of the model and the effectiveness of the identification process.

Evolutionary computing techniques, including genetic algorithms (GA), particle swarm optimization (PSO) and ants system (AS) are applied to the localization problem of a mobile robot. Salient features of robot localization are that the system is partially dynamic and information for fitness evaluation is incomplete and corrupted by noise. In this research, variations to the above three evolutionary computing techniques are proposed to tackle the specific dynamic and noisy system. Their performances are compared based on simulation and experiment results and the feasibility of the proposed approach to mobile robot localization is demonstrated.

Peer-to-Peer (P2P) technologies developed rapidly in different directions with various applications and routing mechanisms. Each of them deals with a particular task, and/or provides a specific service. They were developed separately without a unified architecture taking into account all the performance factors of a P2P system. This makes the P2P systems incomplete and their performances far from optimal. This trend also restricts the interoperability amongst the systems because of the lack of standardization in functional architectures of the P2P systems. As a result, tangible benefits for Internet users are limited because the edge-Internet resources are not sharable amongst the systems. Inspired by TCP/IP model, this paper introduces PARM: a Physically-Aware Reference Model for Overlay Internetworking, which is an open reference structure for designing better performance P2P systems. PARM divides major functional P2P system tasks into layers so that they can be tackled individually and efficiently. A Peer Name Service was developed to evaluate the model. The service interprets peer names into their current locations. Simulation results indicate that PARM helps to produce excellent performance overlays. The overlays can achieve desirable features such as decentralization, self-organization, scalability, low overhead and minimal delay penalty.

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

This paper considers trajectory planning problems for autonomous robots in information gathering tasks. The objective of the planning is to maximize the information gathered within a finite time horizon. It is assumed that either the Extended Kalman Filter (EKF) or the Extended Information Filter (EIF) is applied to estimate the features of interest and the information gathered is expressed by the covariance matrix, or information matrix. It is shown that the planning process can be formulated as an optimal control problem for a nonlinear control system with a gradually identified model. This naturally leads to the Model Predictive Control (MPC) planning strategy, which uses the updated knowledge about the model to solve a finite horizon optimal control problem at each time step and only executes the first control action. The proposed MPC framework is demonstrated through solutions to two challenging information gathering tasks: (1) Simultaneous planning, localization, and map building (SPLAM) and (2) Multi-robot Geolocation. It is shown that MPC can effectively deal with dynamic constraints, multiple robots/features and a range of objective functions.

Abstract
Motivation: Protein–protein interaction, mediated by protein interaction sites, is intrinsic to many functional processes in the cell. In this paper, we propose a novel method to discover patterns in protein interaction sites. We observed from protein interaction networks that there exist a kind of significant substructures called interacting protein group pairs, which exhibit an all-versus-all interaction between the two protein-sets in such a pair. The full-interaction between the pair indicates a common interaction mechanism shared by the proteins in the pair, which can be referred as an interaction type. Motif pairs at the interaction sites of the protein group pairs can be used to represent such interaction type, with each motif derived from the sequences of a protein group by standard motif discovery algorithms. The systematic discovery of all pairs of interacting protein groups from large protein interaction networks is a computationally challenging problem. By a careful and sophisticated problem transformation, the problem is solved using efficient algorithms for mining frequent patterns, a problem extensively studied in data mining.
Results: We found 5349 pairs of interacting protein groups from a yeast interaction dataset. The expected value of sequence identity within the groups is only 7.48%, indicating non-homology within these protein groups. We derived 5343 motif pairs from these group pairs, represented in the form of blocks. Comparing our motifs with domains in the BLOCKS and PRINTS databases, we found that our blocks could be mapped to an average of 3.08 correlated blocks in these two databases. The mapped blocks occur 4221 out of total 6794 domains (protein groups) in these two databases. Comparing our motif pairs with iPfam consisting of 3045 interacting domain pairs derived from PDB, we found 47 matches occurring in 105 distinct PDB complexes. Comparing w...

Formalization of topological relations between spatial objects is an important aspect of spatial representation and reasoning. The well-known 9-Intersection Method (9IM) was previously used to characterize topological relations between simple regions, i.e. regions with connected boundary and exterior. This simplified abstraction of spatial objects as simple regions cannot model the variety and complexity of spatial objects. For example, countries like Italy may contain islands and holes. It is necessary that existing formalisms, 9IM in particular, cover this variety and complexity. This paper generalizes 9IM to cope with general regions, where a (general) region is a non-empty proper regular closed subset of the Euclidean plane. We give a complete classification of topological relations between plane regions. For each possible relation we either show that it violates some topological constraints and hence is non-realizable or find two plane regions it relates. Altogether 43 (out of 512) relations are identified as realizable. Among these, five can be realized only between exotic (plane) regions, where a region is exotic if there is another region that has the same boundary but is not its complement. For all the remaining 38 relations, we construct configurations by using sums, differences and complements of discs.

The RCC8 constraint language developed by Randell et al. has been popularly adopted by the Qualitative Spatial Reasoning and GIS communities. The recent observation that RCC8 composition table describes only weak composition instead of composition raises questions about Renz and Nebel's maximality results about the computational complexity of reasoning with RCC8. This paper shows that any consistent RCC8 binary constraint network (RCC8 network for short) can be consistently extended. Given ?, an RCC8 network, and z, a fresh variable, suppose xTyset membership, variant? and T is contained in the weak composition of R and S. This means that we can add two new constraints xRz and zSy to ? without changing the consistency of the network. The result guarantees the applicability to RCC8 of one key technique, (Theorem 5) of [J. Renz, B. Nebel, On the complexity of qualitative spatial reasoning: A maximal tractable fragment of the Region Connection Calculus. Artificial Intelligence 108 (1999) 69123], which allows the transfer of tractability of a set of RCC8 relations to its closure under composition, intersection, and converse.

In this paper, the dynamics of a system of two van der Pol oscillators with delayed position and velocity coupling is studied by the method of averaging together with truncation of Taylor expansions. According to the slow-flow equations, the dynamics of 1: 1 internal resonance is more complex than that of non-1: 1 internal resonance. For 1: 1 internal resonance, the stability and the number of periodic solutions vary with different time delay for given coupling coefficients. The condition necessary for saddle-node and Hopf bifurcations for symmetric modes, namely in-phase and out-of-phase modes, are determined. The numerical results, obtained from direct integration of the original equation, are found to be in good agreement with analytical predictions.

The non-linear normal modes (NNMs) and their bifurcation of a complex two DOF system are investigated systematically in this paper. The coupling and ground springs have both quadratic and cubic non-linearity simultaneously. The cases of omega(1):omega(2) = 1:1, 1:2 and 1:3 are discussed, respectively, as well as the case of no internal resonance. Approximate solutions for NNMs are computed by applying the method of multiple scales, which ensures that NNM solutions can asymtote to linear normal modes as the non-linearity disappears. According to the procedure, NNMs can be classified into coupled and uncoupled modes. It is found that coupled NNMs exist for systems with any kind of internal resonance, but uncoupled modes may appear or not appear, depending on the type of internal resonance. For systems with 1: 1 internal resonance, uncoupled NNMs exist only when coefficients of cubic non-linear terms describing the ground springs are identical. For systems with 1:2 or 1:3 internal resonance, in additional to one uncoupled NNM, there exists one more uncoupled NNM when the coefficients of quadratic or cubic non-linear terms describing the ground springs are identical. The results for the case of internal resonance are consistent with ones for no internal resonance. For the case of 1:2 internal resonance, the bifurcation of the coupled NNM is not only affected by cubic but also by quadratic non-linearity besides detuning parameter although for the cases of 1: 1 and 1:3 internal resonance, only cubic non-linearity operate. As a check of the analytical results, direct numerical integrations of the equations of motion are carried out.

The nonlinear dynamics of a Duffing-van der Pol oscillator under linear-plus-nonlinear state feedback control with a time delay are investigated. By means of the averaging method and Taylor expansion, two slow-flow equations for the amplitude and phase of the primary resonance response are derived, from which the relations between the amplitude and phase of the primary resonance response and all other parameters are obtained, respectively. The singularity analysis of the equation governing the amplitude of the primary resonance response shows that the bifurcation modes are perturbations of the pitchfork bifurcation. Conditions preventing multiple solutions, corresponding to two different kinds of bifurcation modes, are given, since cases for which multiple solutions are available should be avoided. The stable condition for steady-state response is also given by the Routh-Hurwitz criterion. It is also shown that coupled nonlinear state feedback control can be replaced by uncoupled nonlinear state feedback control.

This paper presents a new skew angle estimation algorithm for binary document images based on the FCRM (fuzzy c-regression models) clustering method with the aim to resolve the disadvantages of low accuracy and robustness of the existing approaches. This algorithm consists of four processes. The first process transfers the input image into parallel straight lines through image analysis. The second process uses the operating window selection to accelerate the executing time. The following process magnifies the image by fast interpolation to increase the accuracy of skew angle estimation. Finally, the FCRM method is applied to estimate the skew angle. A test set of 184 documents of different kinds is used to measure the performance of the proposed algorithm. Experimental results show that the proposed method has a high precision rate for different document types; it is able to accurately estimate the skew angles that range between -89° and +89°. © 2006 TFSA.

After two years, I've realized that my colleagues and I are all in the same room, at the same time, but there are four different meetings going on at once. Only one of the meetings is about education research. As an education researcher, I often find the other meetings frustrating, but I have also come to see that there are positives to all four types of meetings. Each meeting has its weaknesses, including the research meeting, and these respective weaknesses are ameliorated by the other meeting types.

In March 2004, SIGCSE members contributed to a mailing list discussion on the question of whether programming should be taught objects first or imperative first. We analyse that discussion, exploring how the CS community debates the issue and whether contributors' positions are supported by the research literature on novice programmers. We applied four distinct research methods to the discussion: cognitive science, rhetorical analysis in the critical tradition, phenomenography and biography. We identify the cognitive claims made in the email discussion and find there is not a consensus in the research literature as to whether the objects first approach or the imperative approach is harder to learn. From the rhetorical analysis, we find that the discussion was not so much a debate between OO-first versus imperative-first, but instead was more for and against OO-first. Our phenomenographic analysis identified and categorized the underlying complexity of the discussion. We also applied a biographical method to explore the extent to which the participants' views are shaped by their own prior experience. The paper concludes with some reflections upon paradigms, and the manner in which the CS discipline community defines itself.

This paper reports on the authors use of the SOLO taxonomy to describe differences in the way students and educators solve small code reading exercises. SOLO is a general educational taxonomy, and has not previously been applied to the study of how novice programmers manifest their understanding of code. Data was collected in the form of written and think-aloud responses from students (novices) and educators (experts), using exam questions. During analysis, the responses were mapped to the different levels of the SOLO taxonomy. From think-aloud responses, the authors found that educators tended to manifest a SOLO relational response on small reading problems, whereas students tended to manifest a multistructural response. These results are consistent with the literature on the psychology of programming, but the work in this paper extends on these findings by analyzing the design of exam questions.

Phosphorus (P) availability was investigated in rhizosphere soils under 4- to 5-year-old, second-rotation Pinus radiata D. Don and understorey grass (browntop, Agrostis capillaris L.) in two P-deficient Andosols (a Pumice Soil and an Allophanic Soil). Pinus radiata rhizosphere had more soil organic matter, greater mycorrhizal hyphal length density, higher acid phosphatase activity, and more concentrated dissolved organic carbon than bulk soil or the rhizosphere of grass species in one or both soils. Concentrations of resin P and organic P in the P. radiata rhizosphere were higher than those in the grass rhizosphere and bulk soils, suggesting that P. radiata rhizosphere processes have a greater potential to accumulate organic P and mobilize soil P than understorey grass rhizosphere processes. This effect was less marked in the Allophanic Soil than in the Pumice Soil, probably because of the higher P-fixing capacity and lower plant-available P concentrations in the Allophanic Soil.

The spatial and time-dependent patterns of selenium (Se) release from similar-sized granules of 4 Se fertilisers, 3 containing sodium selenate (Unitech Agsel, Ravensdown A, and Ravensdown B) and the fourth containing sodium selenate and barium selenate (Selcote Ultra), were evaluated using ryegrass grown on a Se-deficient soil under glasshouse conditions. Four granules (2-3 mm diameter) from each of the 4 fertiliser types having uniform shape and similar weight were placed on the soil surface of trays (0.51 m length, 0.42 m width, 0.15 m depth) at a distance 0.10 m from 2 adjacent sides of the trays, and the Se content of herbage in concentric rings around each granule was periodically measured over 1 year. The amount of Se applied to the trays, calculated by adding herbage Se to the residual fertiliser Se in soil at the end of the trial, was 12-31 g Se/ha. Soil Se concentration at the end of the trial for the Selcote Ultra and Ravensdown A treatments and herbage Se concentration at 10 harvests for all fertiliser treatments decreased exponentially with increased distance from the granules. Herbage Se concentration reached the level considered deficient to animals (0.05 mg/kg) at the centre of the tray (0.12 m from the granules) 4 months after Unitech Agsel application (7% of paddock area). By 9 months all plants in this treatment became deficient in Se. In contrast, 7% of the sward area in the Ravensdown A treatment, and 41% of the sward area in the Ravensdown B and Selcote Ultra treatments, were deficient in Se at this time, but the average herbage Se concentration for the entire tray was above the deficiency level for these 3 fertiliser treatments. The efficiency of the fertilisers in increasing herbage Se concentration per unit weight of Se applied for the first 3 months was: Unitech Agsel ≥ Ravensdown B ≥ Ravensdown A > Selcote Ultra. During the last 3 months, this order was: Selcote Ultra = Ravensdown A > Ravensdown B > Unitech Agsel. © CSIRO 2006.

Soil fluorine (F) concentrations continue to increase in agricultural soils receiving regular applications of phosphatic fertilizer. Continued accumulation of soil F poses a risk to grazing ruminants and may pose a future risk to groundwater quality. This paper examines the range of total F (Ft) concentrations and forms of soluble F species and their relationship to selected soil properties in New Zealand agricultural soils. The Ft and soluble F (soil F extracted with water (Fwater) and 0.01 m KCl (FKCl)) concentrations in 27 soil samples (0-75 mm depth) taken from predominantly pasture sites in the North and South Islands of New Zealand were much less than those reported in the literature for sites contaminated with F from industry. The Ft concentrations ranged from 212 to 617 μg F g-1 soil. The F-toxicity risk to grazing animals in farms at these sites through soil ingestion is small at present, but farms with very large Ft concentrations (i.e. > 500 μg F g-1) need to adopt suitable grazing and fertilizer management practices to avoid future F-toxicity risk. The Ft concentration had very strong positive correlations with both total soil P and total soil Cd concentrations, reflecting the link between P fertilizer use and F accumulation in the soils. It also had significant positive correlations with organic matter and amorphous Al oxides contents, indicating that F is strongly bound to Al polymers adsorbed to organic matter and amorphous Al oxides. The Fwater and FKCl concentrations and free F- ion concentrations in water (F -water) and 0.01 m KCl (F-KCl) extracts were generally two and three orders of magnitude, respectively, less than the Ft concentrations and were much less than the concentrations considered phytotoxic. The Fwater and FKCl concentrations were positively related to soil organic matter content and negatively related to soil pH. Regression models relating Fwater and FKCl concentrations to soil organic matter content and soil pH suggest that F ca...

This paper presents a new multi-objective topology optimization algorithm for continuum structures under multiple loading cases. An expert evaluation method of weights based on grey system theory is proposed to calculate the objective weights when the compromise programming approach is employed as a multi-objective optimization scheme converting the multi-objective problem to a single objective problem. A modified updating scheme with a self-adaptive move limit for design variables is also suggested, SIMP is regarded as density-stiffness interpolation scheme and the optimality criteria method is used as the optimizer. Numerical instabilities, such as checkerboards and mesh dependencies, are also discussed. The validities of these methods in this paper are demonstrated by some numerical applications.

This paper presents a novel methodology, fuzzy tolerance multilevel programming approach, for applying fuzzy set theory and sequence multilevel method to multi-objective topology optimization problems of continuum structures undergoing multiple loading cases. Ridge-type nonlinear membership functions in fuzzy set theory an. applied to embody fuzzy and uncertain characteristics essentially involved by the objective and constraint functions. Sequence multilevel method is used to characterize the different priorities of loading cases at different levels making contribution to the final optimum solution, which is practically beneficial to reduce the subjective influence transferred by using weighted approaches. The solid isotropic material with penalization (SIMP) is adopted as the density-stiffness interpolation scheme to relax the original optimization problem and indicate the dependence of material properties with element pseudo-densities. Sequential linear programming (SLP) is used as the optimizer to solve the multi-objective optimization problem formulated using fuzzy tolerance multilevel programming scheme. Numerical instabilities, such as checkerboards and mesh dependencies are summarized and a duplicate sensitivity filtering method, in favor of contributing to the mesh-dependent optimum designs, is subsequently proposed to regularize the singularity of the optimization problem. The validation of the methodologies presented in this work has been demonstrated by detailed examples of numerical applications

A multi-objective scheme for structural topology optimization of distributed compliant mechanisms of micro-actuators in MEMS condition is presented in this work, in which mechanical flexibility and structural stiffness are both considered as objective functions. The compliant micro-mechanism developed in this way can not only provide sufficient output work but also have sufficient rigidity to resist reaction forces and maintain its shape when holding the work-piece. A density filtering approach is also proposed to eliminate numerical instabilities such as checkerboards, mesh-dependency and one-node connected hinges occurring in resulting mechanisms. SIMP is used as the interpolation scheme to indicate the dependence of material modulus on element-regularized densities. The sequential convex programming method, such as the method of moving asymptotes (MMA), is used to solve the optimization problem. The validation of the presented methodologies is demonstrated by a typical numerical example.

This paper presents a multi-objective programming scheme for the conceptual design of aerodynamic missile's structure using topological optimization approaches, in which both the compliance and eigenfrequency are regarded as static and dynamic optimization objectives, respectively. During the conceptual design of the aerodynamic missile with multiple loadings, both the multilevel sequential programming approach and the compromising programming method are coupled together to settle the associated difficulties when the whole structure of the missile body is considered as a pre-defined design domain. The compromise programming method is first applied to describe the statically loaded multi-stiffness topology optimization, and the dynamic formulation is used to establish the subsequent optimization problem mainly concerned with free vibration. The main advantage of the proposed scheme is the flexibility of dealing with optimal topology designs for the whole structures of aerodynamic missiles with complicated loading cases. Solid isotropic material with penalization (SIMP) is used as the interpolation scheme to indicate the dependence of material modulus upon regularized element densities. The sequential convex programming approach is applied to solve the optimization problem. An engineering application is used to demonstrate the characteristics of the presented methodologies based on the commercial software package of Hyperworks.OptiStruct at Altair(R

This work presents a hybrid fuzzy-goal multiobjective programming scheme for topological optimization of continuum structures, in which both static and dynamic loadings are considered. The proposed methodology for topological optimization first employs a fuzzy-goal programming scheme at the top level for multi-objective problems with static and dynamic objectives. For the static objective with multi-stiffness cases in the fuzzy-goal formulation, a hybrid approach, involving a hierarchical sequence approach or a hierarchical sequence approach coupled with a compromise programming method, is especially suggested for the statically loaded multi-stiffness structure at the sub-level. Concerning dynamic optimization problems of free vibration cases, nonstructural mass, oscillation of the objective function, and repeated eigenvalues are also discussed. Solid Isotropic Material with Penalization density-stiffness interpolation scheme is used to indicate the dependence of material modulus upon regularized element densities. The globally convergent version of the method of moving asymptotes and the sequential linear programming method are both employed as optimizers. Several applications have been applied to demonstrate the validation of the presented methodologies

View description>>
An intensive investigation was conducted to study the distribution of polycyclic aromatic hydrocarbons (PAHs), to show firstly the level of pollution in the agricultural areas and analyses specifically the status of soil polluted by these persistent pollutants in some locations of Xiamen region. Soil samples collected from Jiulong agricultural catchment have been analysed for 16 PAH compounds, using gas chromatography flame ionization detection in order to determine the level of selected PAH components and to identify the factors that may control their distribution and persistence in the area. The main PAHs found in soil samples were the low molecular weight. The total PAHs detected in soil samples ranged from 0.50 to 0.95μg/g soil. The highest values of PAHs were significantly detected in the orange tree leaves, which range from 236.1 to 249.3 μg/g soil showing recent atmospheric inputs of these volatile pollutants. The distribution of PAHs in vegetable were monitored and indicating that the concentration were high and ranged from 8.24 to 58.87 μg/g. Other sediment samples were also collected and analysed from urban sewage (5.26 μg/g dw), aquacultura (0.52 μg/g dw) and industrial areas (from 0.62 to 2.09 μg/g dw), during this investigation. The contamination of Jiulong river estuary and Xiamen Western Sea by PAHs has been then widely justified by wastewater discharges and soil runoffs from these areas. The results, therefore, provide important information on the current contamination status caused by the atmospheric transport and point to the need for urgent actions to stop the release of these hydrocarbons to the environment. The necessity of implementing systematic monitoring of PAHs is also emphasized. © 2006 Science Press. All rights reserved.

Wastewater treatment and reuse is being emphasized due to the shortage of water sources and the continuous deterioration of the aquatic environment. In this study, a novel sponge bioreactor was studied as a low cost, high efficiency alternative for an attached growth biological system. This was designed by combining of number of sponge trays. This emerging technology has many beneficial properties in wastewater treatment and reuse. The approaches towards the conditions for system design were: (i) selection of sponge types; (ii) selection of sponge shapes; and (iii) selection of designated slope of sponge tray. They were determined through a series of experiments using a laboratory-scale unit with synthetic wastewater. It was then tested with a pilot-scale unit at the predetermined optimum conditions. The results indicate that the highest biomass growth was found at the sponge type with a cell count of 7090 cells/in2 (6.45 cm2) The relationship between biomass growth and biological oxygen consumption was well established. The prism-shaped sponge (triangular polyurethane sponge of 7090 cells/in2 with designated slope of sponge tray at 10 degrees) led to the best performance in terms of both organic and nutrient removal efficiency.

Objectives: To describe our experience with early goal-directed therapy (EGDT), corticosteroid administration, and recombinant human activated protein C (rhAPC) administration in patients with severe sepsis or septic shock and an Acute Physiology and Chronic Health Evaluation (APACHE) II score ≥25 in the emergency department (ED). Methods: This was a retrospective case series of a prospectively maintained ED sepsis registry. Data are presented as median (25th, 75th percentile). The setting was an academic tertiary ED with approximately 60,000 annual patient visits. Patients with severe sepsis or septic shock and an APACHE II score ≥25 entered in an ED sepsis registry over a four-month period were included. Patients who received rhAPC in the intensive care unit were excluded. Central venous catheterization for central venous pressure and central venous oxygen saturation monitoring, antibiotics, fluid resuscitation, mechanical ventilation, vasopressors, inotropes, corticosteroids, and rhAPC were initiated by the emergency physicians and continued in the intensive care unit by intensivists. Results: Twenty-four patients were enrolled. Patient characteristics were as follows: age, 79.5 (68.0, 83.5) years; APACHE II score, 31.5 (29.8, 36.0); ED length of stay, 6.5 (4.0, 10.5) hours; predicted mortality, 76.7% (71.9, 86.4); and in-hospital mortality, 45.8%. All patients received broad-spectrum antibiotics, 54.2% completed EGDT, 33.3% received corticosteroids, and 33.3% received rhAPC. Time of antibiotic administration was 1.5 (1.0, 2.0) hours, time of central venous pressure/central venous oxygen saturation monitoring was 1.0 (0.5, 2.5) hour, and time of rhAPC administration was 9.5 (6.8, 10.5) hours after patients met criteria for severe sepsis or septic shock. In-hospital mortality of patients who received rhAPC in addition to other therapies was 25.0%. Conclusions: EGDT, corticosteroid administration, and rhAPC administration are feasible in the ED setting. While th...

Introduction: Hemodynamic monitoring is an important aspect of caring for the critically ill patients boarding in the emergency department (ED). The purpose of this study is to investigate the interrater agreement of noninvasive cardiac output measurements using transcutaneous Doppler ultrasound technique. Methods: This is a prospective observational cohort study performed in a 32-bed adult ED of an academic tertiary center with approximately 65 000 annual patient visits. Patients were enrolled after verbal consent over a 7-month period. The raters were ED personnel involved in patient care. Paired measurements of cardiac index (CI) and stroke volume index (SVI) were obtained from a transcutaneous Doppler ultrasound cardiac output monitor. Results: A convenience sample of 107 (50 women and 57 men) patients with a median age of 49 (32, 62) years was enrolled. One hundred two paired measurements were performed in 91 patients in whom adequate Doppler ultrasound signals were obtainable. The raters included 35 emergency medicine attending physicians, 31 emergency medicine residents, 80 medical students, 47 nurses, and 11 emergency medical technicians. Cardiac index range was 0.6 to 5.3 L/min per square meter, and SVI range was 7.7 to 63.0 mL/m2. The correlation of CI measurements between 2 raters was good (r2 = 0.87; 95% confidence interval, 0.86-1.00; P < .001). Likewise, SVI measurements between 2 raters also showed acceptable correlation (r2 = 0.84; 95% confidence interval, 0.81-0.96; P < .001). Interrater reliability was strong for CI (κ = 0.83 with 92.2% agreement) and SVI measurements (κ = 0.72 with 88.2% agreement). Most patients had an interrater difference below 10% in CI and SVI measurements. Conclusions: Emergency department personnel, regardless of their role in patient care, are able to obtain reliable cardiac output measurements in ED patients over a wide range of CI and SVI. Transcutaneous Doppler ultrasound technique may be an alternative to traditiona...

Severe sepsis and septic shock are as common and lethal as other acute life-threatening conditions that emergency physicians routinely confront such as acute myocardial infarction, stroke, and trauma. Recent studies have led to a better understanding of the pathogenic mechanisms and the development of new or newly applied therapies. These therapies place early and aggressive management of severe sepsis and septic shock as integral to improving outcome. This independent review of the literature examines the recent pathogenic, diagnostic, and therapeutic advances in severe sepsis and septic shock for adults, with particular relevance to emergency practice. Recommendations are provided for therapies that have been shown to improve outcomes, including early goal-directed therapy, early and appropriate antimicrobials, source control, recombinant human activated protein C, corticosteroids, and low tidal volume mechanical ventilation. © 2006 American College of Emergency Physicians.

For the site-specific prescription of fertilizer topdressing in rice cultivation, a non-destructive diagnosis of the rice growth and nutrition status is necessary. Three experiments were done to develop and test a model using canopy reflectance for the non-destructive diagnosis of plant growth and N status in rice. Two experiments for model development were conducted, one in 2000 and another in 2003 in Suwon, Korea, including two rice varieties and four nitrogen (N) rates in 2000 and four rice varieties and 10 N treatments in 2003. Hyperspectral canopy reflectance (300-1,100 nm) data recorded at various growth stages before heading were used to develop a partial least squares regression (PLS) model to calculate plant biomass and N nutrition status. The 342 observations were split for model calibration (75%) and validation (25%). The PLS model was then tested to calculate within-field statistical variation of four crop variables: shoot dry weight (SDW), shoot N concentration (SN), shoot N density (SND) and N nutrition index (NNI) using measured canopy reflectance data from a field of 6,500 m2 in 2004. Results showed that PLS regression using logarithm reflectance had better performance than both the PLS and multiple stepwise linear regression (MSLR) models using original reflectance data to calculate the four plant variables in year 2000 and 2003. It produced values with an acceptable model coefficient of determination (R 2) and relative error of calculation (REC). The model R 2 and REC ranged from .83 to .89 and 13.4% to 22.8% for calibration, and .76 to .87 and 14.0% to 24.4% for validation, respectively. The PLS regression model R 2 was reduced in the test data of year 2004 but the root mean square error of calculation (RMSEC) was smaller, suggesting that the PLS regression model using canopy reflectance data could be a promising method to calculate within-field spatial variation of rice crop growth and N status. © 2006 Springer Science+Business Media, LLC.

n this article, we present findings from our recent empirical study of the critical success factors (CSFs) for software process improvement (SPI) implementation with 34 SPI practitioners. The objective of this study is to provide SPI practitioners with sufficient knowledge about the nature of issues that play a positive role in the implementation of SPI programmes in order to assist them in effectively planning SPI implementation strategies. Through our empirical study we identified seven factors (higher management support, training, awareness, allocation of resources, staff involvement, experienced staff and defined SPI implementation methodology) that are generally considered critical for successfully implementing SPI. We also report on a literature survey of CSFs that impact SPI and identify six factors (senior management commitment, staff involvement, staff time and resources, training and mentoring, creating process action teams and reviews). We compared our empirical study results with the literature and confirmed the factors identified in the literature, and also identified two new CSFs (SPI awareness and defined SPI implementation methodology) that were not identified in the literature. Finally, we analyzed the CSFs identified by different groups of practitioners and found that they are aware of what is imperative for the successful implementation of SPI programmes.

Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil wall. A pseudo-dynamic method is adopted in the present analysis, which considers the effect of phase difference in both the shear and primary waves travelling through the backfill due to seismic excitation. Reinforced soil walls with cohesionless backfill material have been considered in the analysis. Results are presented in graphical and tabular form to show the required tensile force and length of geosynthetic reinforcement to maintain the stability of the reinforced soil wall under seismic conditions. The effects of variation of parameters such as soil friction angle and horizontal and vertical seismic accelerations on the stability of the reinforced soil wall have been studied. With an increase of seismic accelerations in both the horizontal and vertical directions the stability of the reinforced soil wall decreases significantly, and thus greater strength and length of the geosynthetic reinforcement are required to maintain stability of the wall. The seismic vertical acceleration in an upward direction gives higher values of the required geosynthetic tensile strength, and the seismic vertical acceleration in the downward direction yields higher values of the length of geosynthetic reinforcement. Comparisons of the present results with available pseudo-static results are shown, and the limitations of the pseudo-static results are highlighted.

A major challenge for quantum computation in ion trap systems is scalable
integration of error correction and fault tolerance. We analyze a distributed
architecture with rapid high fidelity local control within nodes and entangled
links between nodes alleviating long-distance transport. We demonstrate
fault-tolerant operator measurements which are used for error correction and
non-local gates. This scheme is readily applied to linear ion traps which
cannot be scaled up beyond a few ions per individual trap but which have access
to a probabilistic entanglement mechanism. A proof-of-concept system is
presented which is within the reach of current experiment.

To make online learning more productive, software agent technology has been applied to provide services for learners in order to assist them to construct knowledge in constructivist ways. This paper is focused on the application of software agents in assisting learners to dynamically adjust learning processes. Unlike pedagogical agents, the agents in this application do not hold domain knowledge but simply assist learners to get through learning processes by a variety of supportive services. They assist learners to develop personalized preferred learning plans and to guide them to dynamically adjust learning toward their goals. In this article, the online learning process is first investigated, and an approach to assisting learners to dynamically adjust learning is outlined. Then, the structure of the UOL (unit of learning) database that provides links between a practical learning scenario and the required services is explored. A multi-agent architecture for realizing the services is configured, and the roles of the involved agents are described. After that, the related agent algorithms for guiding learners to dynamically adjust learning are described.

A critical challenge in keyword search over relational data- bases (KSORD) is to improve its result presentation to facilitate users quick browsing through search results. An effective method is to organize the results into clusters. However, traditional clustering method is not applicable to KSORD search results. In this paper, we propose a novel clustering method named TreeCluster. In the first step, we use labels to represent schema information of each result tree and reformulate the clustering problem as a problem of judging whether labeled trees are isomorphic. In the second step, we rank user keywords according to their frequencies in databases, and further partition the large clusters based on keyword nodes. Furthermore, we give each cluster a readable description, and present the description and each result graphically to help users understand the results more easily. Experimental results verify our methods effectiveness and efficiency.

We present, in this paper, two spectral pattern comparison methods for cancer classification using microarray gene expression data. The proposed methods are different from other current classifiers in the ways features are selected and pattern similarities measured. In addition, these spectral methods do not require any data preprocessing which is neccessary for many other classification techniques. Expertimental results using three popular microarray data sets demonstrate the robustness and effectiveness of the spectral pattern classifiers. © 2006 IEEE.

A laboratory study was conducted to investigate the behavior of soil nails embedded in loosely compacted sandy fills. By varying the overburden pressure, the peak pullout force and the load-displacement behavior were determined by carrying out pullout tests in a displacement-rate controlled manner. The test results were compared to other published ones. The present results show that the pullout resistance can be interpreted with conventional soil parameters. The effect of retrained dilatancy, which is considered to be the reason for high pullout resistance in dense materials, is negligible in loose fill materials except under very low stress level. Furthermore, pullout resistance increases with overburden pressure opposed to some field test results reported in the literature which show no systematic trend in pullout resistance with overburden pressure. A numerical model was developed to simulate the mobilization of pullout force in soil nails. It has been shown that a simple one-dimensional spring model can be used to simulate the pullout load-displacement relationship. © 2006 ASCE.

One of the most significant challenges facing the development of linear
optics quantum computing (LOQC) is mode-mismatch, whereby photon
distinguishability is introduced within circuits, undermining quantum
interference effects. We examine the effects of mode-mismatch on the parity (or
fusion) gate, the fundamental building block in several recent LOQC schemes. We
derive simple error models for the effects of mode-mismatch on its operation,
and relate these error models to current fault tolerant threshold estimates.

We discuss the spectral structure and decomposition of multi-photon states.
Ordinarily `multi-photon states' and `Fock states' are regarded as synonymous.
However, when the spectral degrees of freedom are included this is not the
case, and the class of `multi-photon' states is much broader than the class of
`Fock' states. We discuss the criteria for a state to be considered a Fock
state. We then address the decomposition of general multi-photon states into
bases of orthogonal eigenmodes, building on existing multi-mode theory, and
introduce an occupation number representation that provides an elegant
description of such states that in many situations simplifies calculations.
Finally we apply this technique to several example situations, which are highly
relevant for state of the art experiments. These include Hong-Ou-Mandel
interference, spectral filtering, finite bandwidth photo-detection, homodyne
detection and the conditional preparation of Schr\'odinger Kitten and Fock
states. Our techniques allow for very simple descriptions of each of these
examples.

Qubit loss and gate failure are significant problems for the development of
scalable quantum computing. Recently various schemes have been proposed for
tolerating qubit loss and gate failure. These include schemes based on cluster
and parity states. We show that by designing such schemes specifically to
tolerate these error types we cause an exponential blow-out in depolarizing
noise. We discuss several examples and propose techniques for minimizing this
problem. In general this introduces a tradeoff with other undesirable effects.
In some cases this is physical resource requirements, while in others it is
noise rates.

New plane-strain lateral consolidation equations are formulated that neglect the well resistance of vertical drains but are applicable for both Darcian and non-Darcian flow. The results of consolidation analyses using conventional Darcian (linear) flow and the new solution based on non-Darcian (exponential) flow are compared. A good match has been obtained between equivalent plane-strain and axisymmetric solutions. The advantage of the equivalent plane-strain procedure is that it not only matches the average degree of radial (axisymmetric) consolidation but also yields a more realistic excess pore pressure distribution in the lateral direction than the Darcian flow condition. The relevant parameters are illustrated graphically for convenience. Good agreement was obtained between the prediction of the new equivalent plane-strain solution and field data from a test area in Ska-Edeby, Sweden.Key words: plane strain, consolidation, soft clay, vertical drains.

Sorption experiments were used to assess the ability of various materials (sand, compost, packing wood, ash, zeolite, recycled glass and Enviro-media) to remove heavy metal contaminants typically found in stormwater. Compost was found to have the best physicochemical properties for sorption of metal ions (Cu, Zn and Pb) compared with sand, packing wood, ash, zeolite and Enviro-media. The compost sorption of these metal ions conformed to the linear form of the Langmuir adsorption equation with the Langmuir constants (qm) for Zn(II) being 11.2 mg/g at pH 5. However, compost was also found to leach a high concentration of dissolved organic carbon (DOC, 4.31 mg/g), compared with the other tested materials. Various combinations of sand, compost and other materials were observed to have excellent heavy metal removal (75-96% of Zn and 90-93% of Cu), with minimal DOC leaching (0.0013-2.43 mg/g). The sorption efficiency of the different Enviro-media mixes showed that a combination of traditional (sand) and alternative materials can be used as an effective medium for the treatment of dissolved metal contaminants commonly found in stormwater. The application of using recycled organic materials and other waste materials (such as recycled glass) also provides added value to the products life cycle.

Ballast is one of the most commonly used construction materials in railway tracks. Under heavy train loads, ballast is subjected to a high stress level that is always associated with significant track deformation. Consequently, an accurate prediction of the mechanical behavior of ballast under static and dynamic loading conditions is important for the stability of railway tracks. In this paper, the feasibility of using artificial neural networks (ANNs) for modeling the mechanical behavior of railway ballast under static loading is investigated. The database used for the development of the ANN model is obtained from selected literature and comprises a series of 29 large-scale drained triaxial compression tests conducted on three types of commonly used ballast (i.e., basalt, dolomite, and granite). Predictions from the ANN model are compared with the results of experimental tests and with those obtained from the hardening-soil constitutive model in PLAXIS finite-element code. The results indicate that the ANN model is able to accurately predict the stress–strain and volume change behavior of ballast. The plastic dilation and contraction of ballast at various confining pressures and the strain-hardening and postpeak strain-softening behavior of ballast are also well simulated.Key words: ballast, modeling, neural networks, prediction, railway, triaxial tests.

The effect of seasonal variations on ultrafiltration (UF) following pretreatment was investigated in terms of organic removal, removal of fraction, and molecular weight (MW) distribution. The MW range of effluent organic matter (EfOM) in biologically treated sewage effluent during winter (BTSE-W) consisted of large MW. However, the MW ranged from 3000 to 200 daltons in biologically treated sewage effluent in the summer (BTSE-S). During filtration experiments of BTSE-S, the UF NTR 7410 filter showed rapid flux decline with time without pretreatment. FeCl3 flocculation removed the hydrophobic (HP) and hydrophilic (HL) fractions with different trends. In winter the HP fraction was removed up to 68.5%, whereas during the summer season, the HL fraction was removed by up to 59.8%. Flocculation removed large MW organics together with small MW, while PAC removed the majority of small MW organics. The flux decline with adsorption was also more severe than that with flocculation. Considering MW distribution, when large MW was removed by flocculation, the flux decline was minimized, whereas PAC adsorption which removed small MW still decreased the permeate flux.

In this paper, we address the problem of minimizing energy consumption in a CDMA-based wireless sensor network (WSN). A comprehensive energy consumption model is proposed, which accounts for both the transmit and circuit energies. Energy consumption is minimized by jointly optimizing the transmit power and transmission time for each active node in the network. The problem is formulated as a non-convex optimization. Numerical as well as closed-form approximate solutions are provided. For the numerical solution, we show that the formulation can be transformed into a convex geometric programming (GP), for which fast algorithms, such as interior point method, can be applied. For the closed-form solution, we prove that the joint power/time optimization can be decoupled into two sequential sub-problems: optimization of transmit power with transmission time serving as a parameter, and then optimization of the transmission time. We show that the first sub-problem is a linear program while the second one can be well approximated as a convex programming problem. Taking advantage of these analytical results, we further derive the perbit energy efficiency. Our results are verified through numerical examples and simulations. © 2006 IEEE.

Many producers and consumers of legacy training simulator and game environments are beginning to envision a new era where psycho-socio-physiologic models could be interoperated to enhance their environments' simulation of human agents. This paper explores whether we could embed our behavior modeling framework (described in the companion paper, Part 1) behind a legacy first person shooter 3D game environment to recreate portions of the Black Hawk Down scenario. Section 1 amplifies the interoperability needs and challenges confronting the field, presents the questions that are examined, and describes the test scenario. Sections 2 and 3 review the software and knowledge engineering methodology, respectively, needed to create the system and populate it with bots. Results (Section 4) and discussion (Section 5) reveal that we were able to generate plausible and adaptive recreations of Somalian crowds, militia, women acting as shields, suicide bombers, and more. Also, there are specific lessons learned about ways to advance the field so that such interoperabilities will become more affordable and widespread.

This paper describes a multi-national, multi-institutional study that investigated introductory programming courses .. Student participants were drawn from eleven institutions, mainly in Australasia, during the academic year of 2004. A number of diagnostic tasks were used to explore cognitive, behavioural, and attitudinal factors such as spatial visualisation and reasoning, the ability to articulate strategies for commonplace search and design tasks, and attitudes to studying. The results indicate that a deep approach to learning was positively correlated with mark for the course, while a surface approach was negatively correlated; spatial visualisation skills are correlated with success; a progression of map drawing styles identified in the literature has a significant correlation with marks; and increasing measures of richness of articulation of a search strategy are also associated with higher marks. Finally, a qualitative analysis of short interviews identified the qualities that students themselves regarded as important to success in programming. © 2006, Australian Computer Society, Inc.

Purpose: The purpose of this study was to evaluate the psychometric properties of a revised intuition instrument developed for nursing students. Method: Principal component factor analysis was used to establish construct validity, and the Cronbach’s alpha was used to examine reliability. Findings: Statistical analysis resulted in a 26-item intuition instrument with 6 factors accounting for 62% of the variance. The factors were labeled as Feelings That Reassure (27.7%), Spiritual Connections (10.9%), Feelings That Alert (8.4%), Feelings That Forewarn (5.8%), Physical Sensations That Alert (4.7%), and Reading Physical Cues (4.2%). Eigenvalues ranged from 1.100 to 7.225, and factor loadings ranged from .572 to .848. The overall Cronbach’s alpha was .89 with a range of .73 to .85 for each factor. Conclusions: The 26-item intuition instrument showed evidence of construct validity and reliability. Implications: The intuition instrument can serve as a stimulus to foster students’ intuitive abilities.

Although neuroblastoma is characterized by numerous recurrent, large-scale chromosomal imbalances, the genes targeted by such imbalances have remained elusive. We have applied whole-genome oligonucleotide array comparative genomic hybridization (median probe spacing 6 kb) to 56 neuroblastoma tumors and cell lines to identify genes involved with disease pathogenesis. This set of tumors was selected for having either 11q loss or MYCN amplification, abnormalities that define the two most common genetic subtypes of metastatic neuroblastoma. Our analyses have permitted us to map large-scale chromosomal imbalances and high-level amplifications at exon-level resolution and to identify novel microdeletions and duplications. Chromosomal breakpoints (n = 467) generating imbalances >2 Mb were mapped to intervals ranging between 6 and 50 kb in size, providing substantial information on each abnormality. For example, breakpoints leading to large-scale hemizygous loss of chromosome 11q were highly clustered and preferentially associated with segmental duplications. High-level amplifications of MYCN were extremely complex, often resulting in a series of discontinuous regions of amplification. Imbalances (n = 540) <2 Mb long were also detected. Although the majority (78%) of these imbalances mapped to segmentally duplicated regions and primarily reflect constitutional copy number polymorphisms, many subtle imbalances were detected that are likely somatically acquired alterations and include genes involved with tumorigenesis, apoptosis, or neural cell differentiation. The most frequent microdeletion involved the PTPRD locus, indicating a possible tumor suppressor function for this gene. ©2006 American Association for Cancer Research.

This paper presents a hybrid active-passive approach to fault-tolerant control (FTC). It combines the existing active fault-tolerant control techniques with the newly developed passive decentralized unconditionally stabilizing (DUS) control. The FTC system is developed to achieve optimized performance under sensor failures that are most frequently encountered and/or have significant impact on the process, while guaranteeing the stability under any other failures. This approach can significantly reduce the level of complexity of FTC systems, leading to costeffective designs. A stability condition for control systems based on reconstructed virtual sensor outputs is developed. The effectiveness of the proposed method is illustrated by control of a distillation column

View description>>
A polymer gel is a cross-linked polymer which undergoes a reversible volume and/or sol-gel phase transition in response to physiological (temperature, pH and presence of ion in organism fluids) or other external (electric field, light) stimuli. In structurally soft gels, the motion of polymer network and the diffusion of ions easily take place by an external stimulus. A typical function of gel containing ionic groups is to swell under the influence of an electric field, making it useful for wide biomedical applications. In this study, poly(acrylic acid) (PAA) hydrogel network was prepared by free radical polymerization whose average molecular weight between crosslinkes was calculated as 18500 g/mol and its homogeneity assessment evaluated by comparing 30 samples swelling ratios after 48 h soaking in distilled deionized water. The swelling behaviour of PAA under an electric field application was also investigated as a function of cross-linking agent and electric field intensity variation. It is seen that equilibrium swelling ratio of PAA gel increases from 16 (no electric field) to 30 (by application of 300 V/m electric field), however this variation is dependent on the sample location relative to electrodes. The normalized swelling ratio of sample changes by 4.8 to 0.9 relative to its distance from positive electrode. Increasing the concentration of cross-linking agent (EGDMA) from 0.14 to 0.71 molar percent of monomer resulted in 45% decrease of gel volume fraction. It is proven that applying an external electric field can make an improvement in the time-response of the hydrogel expansion phase and swelling behaviour.

There is currently considerable interest in the wear debris and osteolytic potential of different types of bearings used in total joint replacements. The aim of this study was first to characterize the wear and wear particles generated from two different grades of UHMWPE acetabular cups with different levels of crosslinking in a hip joint simulator. Secondly, the results for the polyethylenes were compared to an alumina ceramic-on-ceramic hip prosthesis. The wear rates of the two noncrosslinked material types were very similar at 49±8 mm3 per million cycles for the GUR 1020 and 45.6±1.4 mm3 per million cycles for the GUR 1050. Moderate crosslinking (4 MRad) significantly (P<0.05) reduced the wear rate of the GUR 1020 material by 30 % to 35±9 mm3 per million cycles. High levels of crosslinking of GUR 1050 (10 MRad) produced a highly significant (P<0.01) 80 % reduction in wear volume. Although reduced wear volumes were observed with moderate levels of crosslinking for the 4 MRad GUR 1020 material, little benefit was conveyed by crosslinking, in terms of predicted overall biocompatibility and estimated osteolytic potential. Introducing high levels of crosslinking (10 MRad) into the GUR 1050 material reduced wear and osteolytic potential by up to five-fold compared to the other GUR 1050 materials. However, compared to the non-crosslinked and moderately crosslinked GUR 1020 materials, the highly crosslinked GUR 1050 UHMWPE had only a two-fold lower osteolytic potential. The alumina ceramic-on-ceramic hip prostheses produced extremely low wear rates under both standard and microseparation simulation conditions, and consequently the osteolytic potential of the alumina bearings was estimated to be >20-fold lower than the highly crosslinked polyethylene.

In this paper, we present the results of one aspect of a multinational, multi-institutional study of computer programming students. Specifically, this paper reports on an exploration of relationships between novice programmers' map-drawing styles (landmark, route or survey) and success in a first programming course at tertiary level. Relationships were found between map-drawing style and success of students in introductory programming courses, but there were mediating factors that resulted in some mixed findings between the countries in which data was collected. The results of this study identify some rich areas for further exploration, and suggests how this line of research might progress. © 2006, Australian Computer Society, Inc.

The magnetorheological (MR) shock absorber is one of the most promising new devices for vibration reduction. Many investigations have been carried out on low velocity and frequency applications of MR devices. The use of the MR shock absorber under impact load is of great interest. The now widely used MR damper models, such as the Bingham model, cannot explain sufficiently the shear thinning behavior under impact loads. However, the HerschelBulkley model can be used to explain the same. The main purpose of this study is to analyze the behavior of the MR shock absorber under impact load and to verify the analytical conclusions and experiments. First, some dynamic simulations on the MR shock absorber under impact loads in Matlab and Simulink are carried out. The model describes the dynamic characteristics especially the shear thinning behavior of the shock absorber, based on this model, then analyzes the variations of piston acceleration and back cavity pressure of MR shock absorber at both same and different flow indices. A test rig is developed to test the characteristics of the long-stroke MR shock absorber under impact loads. Comparisons between the simulation and the test results are made to validate our conclusions. The results indicate that the peak acceleration value of the piston rod and the pressure of the back cavity are decided by the peak value and the duration of the impact force. The peak value of the acceleration and the cavity pressure cannot be changed, but the transitional time of the acceleration of the piston and the pressure of the back cavity of MR shock absorber can be controlled by changing the applied current in the electromagnetic coil. MR shock absorbers will be the most promising shock reduction device under an impact environment.

A phase shifter in an alumina woodpile electromagnetic bandgap (EBG) defect waveguide that operates at microwave frequencies is demonstrated. The phase shift is introduced by sequentially adding low dielectric constant rods to the voids directly above the defect waveguide. The addition of the extra rods creates selected phase delay without significantly affecting the transmission performance of the woodpile waveguide. Measured and computed results in Ku-band are presented to confirm the performance of the device. © The Institution of Engineering and Technology 2006.

Uniform image partitioning based on spiral architecture plays an important role in parallel image processing in many aspects such as uniform data partitioning, load balancing, zero data exchange between the processing nodes et al. However, when the number of partitions is not the power of seven like 7, 49, every sub-image except one is split into a few fragments which are mixed together. We could not tell which fragments belong to which subimage. It is an unacceptable flaw to parallel image processing. This paper proposes a method to resolve the problem mentioned above. From the experimental results, it is shown that the proposed method correctly identifies the fragments belonging to the same subimage and successfully collects them together to be a complete subimage. Then, these subimages can be distributed into the different processing nodes for further processing. Copyright © 2006, Inderscience Publishers.

Region Connection Calculus (RCC) is one primary formalism of qualitative spatial reasoning. Standard RCC models are continuous ones where each region is infinitely divisible. This contrasts sharply with the predominant use of finite, discrete models in applications. In a recent paper, Li et al. (2004) initiate a study of countable models that can be constructed step by step from finite models. Of course, some basic problems are left unsolved, for example, how many non-isomorphic countable RCC models are there? This paper investigates these problems and obtains the following results: (i) the exotic RCC model described by Gotts (1996) is isomorphic to the minimal model given by Li and Ying (2004); (ii) there are continuum many non-isomorphic minimal RCC models, where a model is minimal if it can be isomorphically embedded in each RCC model.

An optimisation of derivatisation methods for the simultaneous determination of endocrine disrupting chemicals (EDCs) in water by solid-phase extraction (SPE) gas chromatographymass spectrometry (GCMS) was developed in this study. Seven highly potent EDCs including 17ß-estradiol (E2), estrone (E1), 16a-hydroxyestrone, 17a-ethynylestradiol (EE2), bisphenol A, 4-nonylphenol and 4-tert-octylphenol were selected as the target compounds. The SPE technique, followed by the derivatisation with N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) was used for the extraction recoveries of compounds from water and effluent samples. The stability of the silylation derivatives under different reaction conditions was investigated. The combined use of BSTFA and pyridine as derivatisation reagents, together with the use of hexane as the final solvent, was preferred in order to generate more stable derivatives of EDCs. The relative response factor (RRF) of all derivatives except that of EE2 was stable 120 h after derivatisation. The addition of pyridine as derivatisation reagent with BSTFA can prevent the conversion of EE2 to other products during the reaction. Several parameters that may affect the recovery of EDCs, such as the SPE flow rate, and water properties including aquatic colloid content and surfactant concentration were tested. The results showed that the flow rate (125 mL min-1), colloid concentration (050 mg L-1) and surfactants concentration (010 µg L-1) did not cause significant decrease in the EDCs recovery.

The sorption and desorption of 4-tert-octylphenol in aquatic systems were studied to unravel the underlying controls. The sorption process was relatively slow, reaching a final sorption equilibrium in 10 d. The sorption process was interpreted as consisting of two stages:? an initial rapid adsorption on particle surface followed by a slow intraparticle diffusion. The key parameter affecting the sorption of 4-tert-octylphenol by sediment is the occurrence of colloids, which in turn explains the so-called sediment concentration (SC) effect. This was confirmed by the increasing amount of colloids with increasing SC, and the relative constancy of intrinsic partition coefficient of 4-tert-octylphenol between sediment and water (Kp) and between colloids and water (Kc). Further evidence was from the nonoccurrence of SC effect from the addition of the same amount of colloids in different SC. The adsorption equilibrium is best described by the Freundlich model at low equilibrium concentrations. The adsorption of 4-tert-octylphenol was enhanced in the presence of salts, due to the salting out effect, and a salting constant of 1.3 L/mol was obtained. Desorption experiments showed that the release of 4-tert-octylphenol from contaminated sediments was highly dependent on the age of sediments, with kinetics of desorption being much faster in fresh sediments than in aged sediments.

A new moving load identification method formulated in state space with regularization on the solution is presented. The bridge deck is modeled as an orthotropic rectangular plate, and the loads are modeled as a group of loads moving on top of the bridge deck at a fixed distance and at a constant speed. The Hamilton principle and the modal superposition principle are included in the formulation. Numerical simulations and experimental tests are employed for the verification and illustration on the effectiveness of the proposed method. The effects of different sensor location, different load path eccentricity, different types of measured information, and measurement noise have been investigated, and the effect of the aspect ratio of the bridge deck is also studied. It is concluded that nine sensors collecting information from nine vibration modes would give reasonably accurate identified results over the practical range of aspect ratio of a modern bridge deck. Acceleration responses are preferred over the velocity and strain responses in this study, and the same type of response should be collected for the same supporting beam in the longitudinal direction.

Routing in Ad hoc Networks has received a significant amount of attention. In recent years, the focus of research has been in on-demand (or reactive) routing protocols due to the recognition that these protocols have the potential to achieve higher levels of scalability than proactive routing strategies. However, most on-demand routing protocols proposed to date attempt to increase routing efficiency by using existing knowledge about the destination or by increasing the stability of the routes. Little research has been done to reduce route discovery overhead when no previous destination information is available. We present a number of different strategies, which encourage a more distributed and localised approach to route discovery by allowing each intermediate node during route discovery to make forwarding decisions using localised knowledge and self-selection. The use of self-selection for route discovery enables nodes to independently make route request (RREQ) forwarding decisions based upon a selection criterion or by satisfying certain conditions. The nodes which do not satisfy the selection criterion do not rebroadcast the RREQs. This provides a more effective and efficient search strategy than the use of traditional brute force blind flooding. We implemented our self-selecting route discovery strategies over AODV using the GloMoSim network simulation package, and compared the performance with existing routing protocols. Our simulation results show that a significant drop in the number of control packets can be achieved by giving each intermediate node more authority for self-selection during route discovery. Furthermore, a significant increase in routing performance is achieved as the number of nodes in the network is increased.

Until now, the main focus in ad hoc networking has been improving Routing and Medium Access Control (MAC) Strategies. As a result, a diverse range of routing and MAC protocols have been proposed. To evaluate these protocols, much of the existing research has been based on simulation scenarios which assume ideal channel conditions and low node and traffic densities. Therefore, despite a few studies which have shown the performance limitations of ad hoc networks theoretically, there has not been many simulation studies performed which investigate the performance of ad hoc networks under a high node and traffic density. This paper investigates the performance of ad hoc networks under a high node density and high-bit rate real-time traffic such as VoIP. Our results show that the performane of single radio ad hoc networks drops significantly as traffic density is increased. To improve the performance of ad hoc networks, a number of different strategies and research areas are described.

The Virtual Critical Care Unit, (ViCCU®) is a telemedicine system that allows a specialist at a major referral hospital to direct a team in a rural hospital. ViCC® allows remote consultation to take place based on the transmission of multiple channels of real-time video/audio information of the patient, the clinical team, x-ray/paper documents and patient vital signs from the remote site to the specialist. This paper explores clinicians' experience of presence in a telemedicine application. In this study we used a modified version of the Slater-Usoh-Steed (SUS) presence questionnaire to measure clinicians' sense of presence when using ViCC®. We also explored the relationship between presence felt when using ViCCU® and personal, usability and media factors. Initial results indicate that in this context, personal factors influenced clinicians experience of presence and that there was a positive relationship between presence and both usability and media factors. Reflection on some of the challenges in conducting this study in an emergency department and the appropriateness of the SUS presence measure in this real setting are also included.

Knowledge of calibration, that defines the location of sensors relative to each other, and registration, that relates sensor response due to the same physical phenomena, are essential in order to be able to fuse information from multiple sensors. In this paper, a mutual information (MI) based approach for automatic sensor registration and calibration is presented. Unsupervised learning of a nonparametric sensing model by maximizing mutual information between signal streams is used to relate information from different sensors, allowing unknown sensor registration and calibration to be determined. Experiments conducted in an office environment are used to illustrate the effectiveness of the proposed technique. Two laser sensors are used to capture people mobbing in an arbitrarily manner in the environment and MI from a number of attributes of the motion are used for relating the signal streams from the sensors. Thus the sensor registration and calibration is achieved without using artificial patterns or pre-specified motions

A total of 107 papers from two conferences, one Australasian and the other American were analysed, using a framework which posed the following four questions. What questions are being asked? What theoretical positions are being taken? What counts as evidence in answering those questions? What is the educational significance of what has been found? There was clear evidence of varied approaches to undertaking e-learning research. The nature of the research questions reported support the view that there is a degree of repetition in current research projects, and a reluctance to tackle the big issues. The authors recommend that researchers move away from narrowly focused questions to an approach focused on the systems nature of student learning.

We describe the use of a kernel-based approach using the Laplacian matrix to visualize an integrated Chronic Fatigue Syndrome dataset comprising symptom and fatigue questionnaire and patient classification data, complete blood evaluation data and patient gene expression profiles. We present visualizations of the individual and integrated datasets with the linear and Gaussian kernel functions. An efficient approach inspired by computational linguistics for constructing a linear kernel matrix for the gene expression data is described. Visualizations of the questionnaire data show a cluster of non-fatigued individuals distinct from those suffering from Chronic Fatigue Syndrome that supports the fact that diagnosis is generally made using this kind of data. Clusters unrelated to patient classes were found in the gene expression data. Structure from the gene expression dataset dominated visualizations of integrated datasets that included gene expression data. © 2006, Australian Computer Society, Inc.

Signature identification and verification has been a topic of interest and importance for many years in the area of biometrics. In this paper we present an effective method to perform off-line signature verification and identification. To commence the process, the signature's contour is first determined from its binary representation. Unique structural features are subsequently extracted from the signature's contour through the use of a novel combination of the Modified Direction Feature (MDF) in conjunction with additional distinguishing features to train and test two Neural Network-based classifiers. A Resilient Back Propagation neural network and a Radial Basis Function neural network were compared. Using a publicly available database of 2106 signatures containing 936 genuine and 1170 forgeries, we obtained a verification rate of 91.12%. © 2006 IEEE.

This paper presents an effective method to perform off-line signature verification using unique structural features extracted from the signature's contour. A novel combination of the Modified Direction Feature (MDF) and additional distinguishing features such as the centroid, surface area, length and skew are used for classification. A Resilient Backpropagation (RBP) neural network and a Radial Basis Function (RBF) network were compared in terms of verification accuracy.

The problem of a line source radiating in the presence of a multilayered metamaterial cylinder is solved analytically and implemented numerically. Results for both the source and scattering problems demonstrate that electrically small cylindrical structures can be designed to be resonant leading to enhancements of the radiated and scattered powers. The effects of the dispersion present in the metamaterials are taken into account to study the bandwidth properties of the configurations at hand. © 2006 IEEE.

An antenna configuration consisting of an arbitrarily located electric line source radiating in the presence of concentric metamaterial cylinders is examined. In particular, the near field, the directivity, and the differential scattering cross section are investigated for specific metamaterial structures, and these results are compared to those for the corresponding structures based on double-positive materials. It is shown that specific electrically small metamaterial structures possess radiation and scattering features that surpass those of the corresponding double-positive material structures.

To satisfy customer requirements and simultaneously fully utilize the production machines, there is a need to determine appropriate cycle time. Especially in pull systems with varying product mixes, accurate cycle time is even more crucial. Accurate cycle time also reduces the need for buffers. When the product mix varies, especially in a pull production system with parallel flow, determination of accurate cycle time becomes problematic. Hence this paper studies the relations between cycle times and product mixes in a parallel pull production system using discrete event simulation. Experiments with varying product mixes for parallel production systems are simulated. The simulation results show that optimal cycle time is inversely proportional to product mixes, when the product mix is 50:50 e.g. 120 sec. should be set to each parallel machine to obtain overall cycle time of 60 sec. However, when the mixes are more than 50:50, the proportional rule is not valid. © 2006 IEEE.

This study presents an integrated genetic algorithm (GA) and artificial neural network (ANN) to estimate and predict electricity demand using stochastic procedures. The economic indicators used in this paper are price, value added, number of customers and consumption in the previous periods. This model can be used to estimate energy demand in the future by optimizing parameter values. The GA applied in this study has been tuned for all its parameters and the best coefficients with minimum error are identified, while all parameter values are tested concurrently. The estimation errors of genetic algorithm model are less than that of estimated by regression method. Neural network is used to forecast each independent variable and then electricity consumption is forecasted up to year 2008.It is shown that neural networks dominate time series approach form the point of yielding less Mean Absolute Percentage Error (MAPE) error.. In addition, another unique feature of this study is utilization of ANN instead of time series to obtain better predictions for energy consumption. Electricity consumption in Iranian agriculture sector from 1981 to 2005 is considered as the case of this study. © 2006 IEEE.

efficiency frontier analysis has been an important approach of evaluating firms' performance in private and public sectors. There have been many efficiency frontier analysis methods reported in the literature. However, the assumptions made for each of these methods are restrictive. Each of these methodologies has its strength as well as major limitations. This study proposes a non-parametric efficiency frontier analysis method based on the adaptive neural network technique for measuring efficiency as a complementary tool for the common techniques of the efficiency studies in the previous studies. The proposed computational method is able to find a stochastic frontier based on a set of input-output observational data and do not require explicit assumptions about the function structure of the stochastic frontier. In this algorithm, for calculating the efficiency scores, a similar approach to econometric methods has been used. Moreover, the effect of the return to scale of decision making unit (DMU) on its efficiency is included and the unit used for the correction is selected by notice of its scale (under constant return to scale assumption). An example using real data is presented for illustrative purposes, in the application to the power generation sector of Iran, we find that the neural network provide more robust results and identifies more efficient units than the conventional methods since better performance patterns are explored. Moreover, principle component analysis (PCA) and numerical taxonomy (NT) are used to verify the findings of the purposed algorithm.

This paper presents an integrated fuzzy system and data mining approach for estimation of electricity demand function in Iran. To construct fuzzy systems, a rule base is needed. Because a rule base is not available, for the case of demand function, look up table which is one of the extracting rule methods is used to extract the rule base. But the extraction by look up table in this case (demand function) operates poorly. Therefore, decision tree method which is a data mining approach is utilized to extract the rule base. It can be seen that this method provides better solution. The case study is based on the total electricity consumption in Iran from 1992 to 2004. The prescribed approach may be an ideal substitute for fuzzy regression. At last, relative results of the mentioned methods are compared with ARIMA (Auto Regressive Integrated Moving Average) model, which is one of the most famous time series models.

Poisson Arrivals See Time Averages (PASTA) is a well known property applicable to many stochastic systems. In active probing, PASTA is invoked to justify the sending of probe packets (or trains) at Poisson times in a variety of contexts. However, due to the diversity of aims and analysis techniques used in active probing, the benefits of Poisson based measurement, and the utility and role of PASTA, are unclear. Using a combination of rigorous results and carefully constructed examples and counter-examples, we map out the issues involved, and argue that PASTA is of very limited use in active probing. In particular, Poisson probes are not unique in their ability to sample without bias. Furthermore, PASTA ignores the issue of estimation variance, and the central need for an inversion phase to estimate the quantity of interest ased on what is directly observable. We give concrete examples of when Poisson probes should not be used, and explain why, and offer initial guidelines on suitable alternative sending processes.

Power sector reforms in India were initiated in the face of mounting commercial losses due to poor fiscal health of State Utilities, endemic capacity and energy shortages and increasing subsidy burden on the states. Investment in the sector was falling far short of demand in power supply. The Government of India, in 1991 embarked upon an ambitious program for reforming the sector with the prime objective of transforming the electricity industry into an efficient enterprise. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reform process. The paper delineates the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactment which has come into force in the form of the Electricity Act, 2003 and seek a paradigm shift. Several key elements of the reform program have been implemented by the various states, with varying degree of success, during the period 1991-2005. This paper reviews the performance of the Indian power sector in the last one and half decade since the reforms had been initiated, while undergoing restructuring. The study also examines how far the reform process during this period has been effective in realizing its set objectives and benefited the development of the power sector and the nation at large. The paper briefly discusses the issue involved in introduction of competition in the power sector primarily through development of a market for bulk power.

Biologically realistic computer simulation of vertebrates is a challenging problem with exciting applications in computer graphics and robotics. Once the mechanics of locomotion are available it is interesting to mediate this locomotion with higher level behavior such as target tracking. One recent approach simulates a relatively simple vertebrate, the lamprey, using recurrent neural networks to model the central pattern generator of the spine and a physical model for the body. Target tracking behavior has also been implemented for such a model. However, previous approaches suffer from deficiencies where particular orientations of the body to the target cause the central pattern generator to shutdown. This paper describes an approach to making target tracking more robust.

AbstractSheet resistance (Rs) reductions are presented for antimony and arsenic doped layers produced in strained Si. Results re-emphasise the Rs reduction for As comes purely as a result of mobility improvement whereas for Sb, a superior lowering is observed from improvements in both mobility and activation. For the first time, strain is shown to enhance the activation of dopant atoms whilst Sb is seen to create stable ultra-shallow junctions. Our results propose Sb as a viable alternative to As for the creation of highly activated, low resistance ultra-shallow junctions for use with strain-engineered CMOS devices.

Support for software extensibility, interoperability and reuse are critical concerns for long term commercial viability of any MAS and they underpin the eventual adoption of agent technology by industry. Existing AOSE methodologies lack adequate support for these concerns. We argue in this paper that a methodology that uses ontologies as a central modelling artifact, beyond the analysis phase, is better equipped to address those concerns. We observe that the influence of ontologies in Knowledge-based Systems (KBS) methodologies extended well beyond the initial analysis phase, leading to domain-independent KBS methodologies in the 90s. We reflect on those lessons and on the roles of ontologies in KBS development. We analyse and identify which of those roles can be transferred to an ontology-based MAS development methodology. We identify ontology-related inter-dependencies between the analysis and design phases. We produce a set of recommendations towards creating a domain-independent MAS methodology that incorporates ontologies beyond the analysis phase. We identify the essential features and sketch the characteristic tasks within both the analysis and design phases.

This paper presents a novel solution for efficient representation of multi-channel spatial audio signals. Unlike other spatial audio coding techniques, the solution inherently requires no additional side information to recover the surround sound panorama from a two-channel downmix. For a typical five-channel case, only a stereo downmix signal is required for the decoder to reconstruct the full five-channel audio signal. In addition to the bandwidth saved by transmitting no side information, the technique has significant advantages in terms of computational complexity. © Springer-Verlag Berlin Heidelberg 2006.

Formalising nearness has been the subject of extensive work, resulting in many membership functions based on absolute distance metrics, relative distance metrics, and combinations of those. The possible strengths and weaknesses of these functions have been discussed and argued at length, but strangely enough, no experiment seems to have been conducted to assess the merits and shortcomings of competing approaches. Conducting such experiments can be expected not only to provide an objective evaluation of the various measures that have been proposed, but also to suggest new measures that outperform all those being analysed. This paper fulfills these expectations, and gives further evidence that fuzzy logic provides fruitful and powerful methods to formalise qualitative reasoning and capture fundamental qualitative notions. The proposed fuzzy membership functions can be directly used in qualitative reasoning about spatial proximity in Geographic Information Systems, which are becoming more and more important in software development for diverse purposes such as Tourist Information Systems or property development.

Stress is becoming an increasingly critical parameter for all steps in back-end-of-line integration. As the k-value of dielectric spacers decreases their mechanical integrity scales accordingly, making the interconnect stack increasingly sensitive to barrier and copper stresses. These stresses need to be studied not only for as-deposited layers, but also during thermal processing. Stress relaxation of the barrier can for instance occur at elevated temperatures and result in severe dielectric deformation. Copper typically relaxes at elevated temperatures during thermal cycling and then builds-up thermal stress when cooled back to room temperature. However, the initial stress state can have a strong effect on the final microstructure. An example is shown here where a new growth mode, named 'super-secondary-grain-growth, is stress induced and leads to grains of many tens of microns. © 2006 American Institute of Physics.

AbstractIn the quest for ever smaller, lighter weight, and conformal components and devices for radar and communication applications, researchers in the RF community have increasingly turned to artificially engineered, composite structures (or “metamaterials”) in order to exploit the extraordinary electromagnetic response these materials offer. One particularly promising class of metamaterials that has recently received a great deal of attention are “left-handed” or negative index materials. Because these metamaterials exhibit the unique ability to bend and focus light in ways no other conventional materials can, they hold great potential for enabling a number of innovative lens and antenna structures for a broad range of commercial and DoD relevant applications. Exploring the possible implementation of negative index materials for such applications will require significant enhancements in the properties of existing Negative Index Materials (NIM) (bandwidth, loss, operational frequency, etc.), as well as improved understanding of the physics of their electromagnetic transport properties. For this reason the Defense Advanced Research Project Agency (DARPA) has initiated a program that seeks to further develop and demonstrate NIM for future DoD missions including, but not limited to, the following: 1) lightweight, compact lenses with improved optics; 2) sub wavelength/high resolution imaging across the electromagnetic spectrum; 3) novel approaches to beam steering for radar, RF, and/or optical communications; and 4) novel approaches for integrating optics with semiconductor electronics. A brief overview of the salient properties of NIM will be presented as well as a general discussion of a few of their potential applications.

This paper presents the bridge damage detection from the response of the vehicle moving on a simply supported bridge discretized into m Euler beam elements based on dynamic response sensitivity analysis respect to bridge damage indices. The moving vehicle is modeled as a one-degree-of-freedom system comprising three parameters. The response of the vehicle and its sensitivity respect to bridge parameters can be solved by Newmark method. The bridge damage described as reduction of bridge bending stiffness of each element. Starting with zero initial damage indices vector, the identification can be realized based on the combination of least-squares method and regularization technique from the simulated measured vehicle acceleration measurements. Simulation studies indicate that the identified results are acceptable and the identification method is practicable and effective. © 2006 Taylor & Francis Group.

Node mobility is one of dominant factors causing decreased performance in mobile ad hoc networks and restricting network scalability. Selecting stable paths is an effective way to reduce the impact of node mobility. Current methods of selecting stable paths suffer from several shortcomings. They may need a hardware function support for geographical position location or cross-layer function support for sending signal strength information to upper layers. In this paper a new simple method for selecting stable paths is proposed. This method uses a Neighbor Change Ratio metric and does not require any hardware function or cross layer support. The method selects paths which have small hop counts and stable local topologies. An extension to the AODV routing protocol is used as an example of using the Neighbor Change Ratio metric. The resulting NCR-AODV protocol is simulated under various mobility and traffic scenarios. The results show that the NCR-AODV protocol has a lower long path break probability and improved network performance compared to the AODV protocol. © 2006 IEEE.

The ability to fabricate strong and extraordinarily stable Bragg gratings in any type of fibre using femtosecond laser light has attracted much interest in the recent past. The induced index change has been attributed to glass densification brought about by nonlinear multiphoton ionisation resulting in bond breaking, local melting and rapid cooling occurring after optical breakdown by the high-energy femtosecond light. In this paper, a preliminary comparative study between fibre Bragg grating fabrication in germanosilicate fibre using 244nm femtosecond source with a repetition rate of 250kHz and 200fs pulse duration and a 244nm CW frequency doubled argon-ion source is presented. The reflectivities achieved in both cases were close to identical for similar writing fluences, as were the isochronal annealing profiles. This indicated that despite the very high repetition rate used, the collective heat generated by the femtosecond radiation plays no role in the compaction of the glass matrix. The index change observed in this case is a result of single photon absorption into known defect centres - the laser intensity was insufficient to excite the glass band edge leading to glass compaction. No qualitative difference in index change between CW and short-pulse excitation of these defects is found.

Photonic crystal fibres and air-clad fibres have opened up unprecedented opportunities in laser-based technologies, including defence, material processing and sensing. The presence of air holes benefits sensing and permits the general introduction of materials for applications as diverse as switching and modulation. Of particular note are air clad fibre lasers, which are an increasingly preferred alternative to polymer clad fibre lasers for high power operation. The ability to incorporate gratings, including DFB structures, into these Fibres paves the way for future all-fibre topologies where bulk optics need not be necessary. However, significant research effort remains to ensure that this potential is fulfilled. A review of the work carried out at the OFTC highlighting their properties and potential is presented.

Stock data mining such as financial pairs mining is useful for trading supports and market surveillance. Financial pairs mining targets mining pair relationships between financial entities such as stocks and markets. This paper introduces a fuzzy genetic algorithm framework and strategies for discovering pair relationship in stock data such as in high dimensional trading data by considering user preference. The developed techniques have a potential to mine pairs between stocks, between stock-trading rules, and between markets. Experiments in real stock data show that the proposed approach is useful for mining pairs helpful for real trading decision-support and market surveillance.

The diffusion of management techniques is as difficult as the diffusion of technologies. This paper aims to find out how technology management is perceived and utilized in Turkish firms. The research is based on a survey that consists of 89 company responses out of the biggest 500 firms in the Turkish industry. The investigation consists of 1) the degree of diffusion in terms of technology management activities such as technology planning as well as 2) the techniques and tools used in technology management such as simulation. The literature review indicates 11 technology management activities ranging from strategy to utilization and 36 technology management techniques / tools. The results show that Turkish managers try to utilize technologies rather than creating them and they use 11 techniques more often than others and many important tools such as technology life cycle are not diffused yet.

The growing development of web-based reputation systems in the 21 century will have a powerful social and economic impact on both business entities and individual customers, because it makes transparent quality assessment on products and services to achieve customer assurance in the distributed web-based Reputation Systems. The web-based reputation systems will be the foundation for web intelligence in the future. Trust and Reputation help capture business intelligence through establishing customer trust relationships, learning consumer behavior, capturing market reaction on products and services, disseminating customer feedback, buyers' opinions and end-user recommendations. It also reveals dishonest services, unfair trading, biased assessment, discriminatory actions, fraudulent behaviors, and un-true advertising. The continuing development of these technologies will help in the improvement of professional business behavior, sales, reputation of sellers, providers, products and services. Given the importance of reputation in this paper, we propose ontology for reputation. In the business world we can consider the reputation of a product or the reputation of a service or the reputation of an agent. In this paper we propose ontology for these entities that can help us unravel the components and conceptualize the components of reputation of each of the entities. © Springer-Verlag Berlin Heidelberg 2006. st

This paper presents a generalized dynamic model for flyback switching AC-DC converters. Comparing with the current model in the published literatures, several important factors are taken into account, including the anomalous loss in magnetic cores, differential inductance and leakage inductance. In order to obtain accurate parameters, nonlinear finite element analysis method is used to calculate some key parameters of transformer: differential inductance and leakage inductance. Furthermore, a modified flyback transformer model is built. The systematic method to build the hybrid model-system switching state based on time sequence is also introduced. A simulation model in MATLAB/Simulink, in which all three operational modes are included, is built. The developed model is validated by executing the model on an existing converter, and several performances are obtained.

This paper presents an improved phase variable model and field-circuit coupling method for the design and performance analysis of a high speed surface mounted permanent magnet brushless DC motor. In the design of the motor, magnetic field finite element analysis is conducted to calculate the key motor parameters such as the air gap flux, back electromotive force, and inductance, etc. Based on the numerical magnetic field solutions, a modified incremental energy method is employed to effectively calculate the self and mutual inductances of the stator windings. An equivalent electrical circuit is derived to predict the motor characteristics. In order to study the comprehensive performance of the motor at the design stage, especially the motor output speed and torque at high speeds, which are affected by the dynamic inductances, an improved phase variable model is introduced to simulate the motor performance. The motor prototype has been constructed and tested with both a dynamometer and a high speed embroidery machine, which validates successfully the theoretical calculations.

Based on the mathematical model of flyback switching DC-DC converter in the continuous current mode and the simulation model under heavy loads, this paper presents a study of the steady-state power loss in the output diode, including the loss calculation models under three operational modes (voltage control, under-voltage, and overcurrent modes), the relations of the diode loss versus the input and output voltages, and a comparison of the losses under different modes. By the heavy load simulation model, the effects of time delay on the diode loss are also investigated. Finally, the proposed models are applied to calculate the power losses of output diode of an existing flyback switching DC-DC converter.

As multiparty meetings involve participants that are generally stationary when actively speaking, participant location information can be used to segment the recorded meeting audio into speaker 'turns.' In this paper, speaker location information derived from 'spatial cues' generated by spatial audio coding techniques is investigated. The validity of using spatial cues for meeting audio segmentation is explored through investigating multiple microphone meeting audio recording techniques and different spatial audio coders. Experimental results show that the statistical relationship between speaker location and interchannel level and phase-based spatial cues strongly depends on the microphone pattern. Results also indicate that interchannel correlation-based spatial cues represent location information that is ambiguous for meeting audio segmentation.

Multiparty meetings generally involve stationary participants. Participant location information can thus be used to segment the recorded meeting speech into each speaker's 'turn' for meeting 'browsing'. To represent speaker location information from speech, previous research showed that the most reliable time delay estimates are extracted from the Hubert envelope of the Linear Prediction residual signal. The authors' past work has proposed the use of spatial audio cues to represent speaker location information. This paper proposes extracting spatial audio cues from the Hubert envelope of the speech residual for indicating changing speaker location for meeting speech segmentation. Experiments conducted on recordings of a real acoustic environment show that spatial cues from the Hilbert envelope are more consistent across frequency subbands and can clearly distinguish between spatially distributed speakers, compared to spatial cues estimated from the recorded speech or residual signal. © 2006 IEEE.

This paper explores user-centered metadata delivery through the example of hierarchically organized meeting audio metadata. Audio annotations that describe meeting scenarios can vary from low-level signal-based descriptors to high-level semantics. Users of meeting metadata also have widely varying requirements and hence want metadata at varying levels and detail. Thus, for efficient metadata access, it is vital to provide customization or choice of the metadata to be delivered using e.g. regions of interest and annotation detail specification. As well as proposing a user-centered metadata organization strategy, this paper introduces the use of a bi-directional XML protocol for metadata delivery. The combination provides advantages in terms of bandwidth efficiency when an example meeting metadata browser application is examined with practical user interfaces. ©2006 IEEE.

Matching of single individuals as they move across disjoint camera views is a challenging task in video surveillance. In this paper, we present a novel algorithm capable of matching single individuals in such a scenario based on appearance features. In order to reduce the variable illumination effects in a typical disjoint camera environment, a cumulative color histogram transformation is first applied to the segmented moving object. Then, an incremental major color spectrum histogram representation (IMCSHR) is used to represent the appearance of a moving object and cope with small pose changes occurring along the track. An IMCHSR-based similarity measurement algorithm is also proposed to measure the similarity of any two segmented moving objects. A final step of post-matching integration along the object's track is eventually applied. Experimental results show that the proposed approach proved capable of providing correct matching in typical situations

In recent years, a great deal of attention has been focused on the condition and safety of aging timber bridges in Australia. Vibration-based damage identification techniques to detect structural deterioration at an early stage have significant potential to reduce the costs and down-time associated with repair of damaged members as well as enhancing the safety and reliability of timber bridges. In this paper, the process of developing and calibrating a scale timber bridge, which accurately simulates the behaviour of a ?real? bridge under laboratory conditions, is presented. A finite element (FE) model has been developed and calibrated with experimental modal data. The FE model shows acceptable correlations when compared to the experimental data, with minor adjustment of the actual material properties. It forms a tool for predicting the behaviour of the damaged laboratory bridge, as well as potential identification of damage in real timber bridges.

Damage identification techniques have been widely investigated and used for structural damage evaluation. Many researchers have shown good results in detecting, locating and quantifying damage in structures using various damage identification algorithms and methods. One of the popular and promising damage identification methods is modified damage index (MDI) which utilises modal strain energy (MSE) and a statistical approach. However, when using this damage identification method, numerical techniques used in realising the damage detection algorithm plays an important role for the final outcome. The use of different techniques in detection of damage has not been widely investigated. In this paper, a finite element (FE) model of a timber beam was developed as a test structure. Modal responses of the test structure were generated using a FE software package. The damage index algorithm, utilising modal strain energy as its damage indicator, was computed. In the computation process, different numerical techniques at different stages were utilised to process the data. Since in practice, the number of modal data is usually limited, it is recommended that the mode shape data to be expanded using mode shape reconstruction technique. Thus, the raw data was reconstructed using two different mode shape reconstruction techniques, namely Shannon's sampling theorem and cubic spline. The computation of MDI is enabled by numerical integration method. In this paper, two numerical integration methods were performed viz trapezoidal and rectangular rules. The manipulated data is subsequently transformed into standard normal space. The mode shape was mass normalised and the mode shape curvature was normalised with respect to the maximum value of each considered mode. For practicality purposes, the first two flexural mode shapes were used in the algorithms computation. Among the two proposed numerical integration methods, the rectangular rule has shown greater potential. The cubic spli...

View description>>
Knowledge of the dynamic earth pressure is essential for the safe design of retaining wall in the seismic zone due to the devastating effect of earthquake. In this paper the seismic earth pressure on a rigid retaining structure for both active and passive conditions are determined by pseudo-dynamic method. Conventional pseudo-static approach gives the linear distribution of seismic earth pressure behind retaining wall in an approximate way. However, the proposed pseudodynamic method gives the non-linear distribution of seismic earth pressure in more realistic manner by considering the variation of shear and primary wave velocities along the depth of the wall combined with the horizontal and vertical seismic accelerations. Movement of the wall with respect to soil guides the formation of active or passive earth pressure along with the frictional force at soil-wall. Results are presented in graphical form for non-dimensional seismic earth pressure distribution for different cases of wall friction angle under both active and passive conditions. Design values of the seismic earth pressure coefficients are found to change significantly under seismic conditions. Comparison of present results with pseudo-static approach describes the necessity and merits of the present solution.

In the past decade, artificial neural networks (ANNs) have been widely applied to the engineering problems with a complicated system. ANNs are becoming an important alternative option for solving problems in comparison to traditional engineering solutions, which are usually involved in complicated mathematical theories. In this study, we apply an ANN model to the wave-induced seabed liquefaction problem, which is a key issue in the area of coastal and ocean engineering. Furthermore, we adopted an ANN model with preprocessing (MIN-MAX) on difficult training data. This paper demonstrates the capacity of the proposed ANN model using MIN-MAX pre-processing to provide coastal engineers with another effective tool to analyse the stability of seabed sediment. © 2006 IEEE.

View description>>
In UWB system design and optimization, antennas are usually represented by a single transfer function relating the input voltage to the radiated electric field in the free space. However, the transfer function of planar ultra-wideband antennas depends on not only frequency but also direction. In this paper we present a strategy that helps the UWB system designer to select the best transfer function (and the best reference direction) for the antenna. In the process we demonstrate that good pattern stability of a UWB antenna within a particular band is advantageous to ease the complexities in the selection of the transfer function. We have thus emphasized the importance of having stable patterns for UWB antennas. Pulse optimization algorithms that meet FCC spectrum requirements are presented as examples.

In ultra-wideband (UWB) system development, antennas have to be assessed with respect to their impedance matching and radiation performance. Impedance matching is easily expressed as return loss but the quantification of radiation performance is not so obvious. Nevertheless it is crucial to ensure that the antenna has a sufficiently stable pattern in the directions of interest, over the operating bandwidth, or in other words the antenna transfer function does not vary significantly over the range of operating directions. It has been proposed that this assessment can be conducted with the help of the Pattern Stability Factor (PSF), PSF enables one to compare two or more antennas for pattern stability, define pattern-stable bandwidth of an antenna as well as overall bandwidth of an antenna, and assess the effect of antenna device integration on radiation performance. Calculation of PSF can be done easily with either the impulse response in the time domain or directional transfer functions in the frequency domain. Transfer functions are acquired through time domain electromagnetic simulation followed by Fourier transform or wide-band sweeps in a frequency-domain simulation. Experimental determination of PSF can be done with conventional antenna range measurements or with two port scattering parameter measurements using a vector network analyzer. In this paper we will present preliminary results of the former.

The waveform of the electric field radiated by an antenna in a UWB system is usually a distorted form of the input pulse applied at the terminals. This distortion can be expressed in terms of the antenna impulse response in the time domain or directional transfer function in the frequency domain. Even for a simplest antenna like a linear dipole, the impulse response can be direction dependent. However, if the antenna's response in different directions are unrelated, modeling of such antennas with other elements of the UWB system can be complicated. Therefore, it is better to design antennas with consistent performance in all the directions of interest as far as possible. As the radiation patterns of UWB antennas can be measured easily, using standard antenna testing methods, it is useful to establish the link between the correlation of far-field waveforms in different directions and the frequency stability of the radiation pattern, when designing antennas with good UWB performance.

View description>>
In this paper, we consider the problem of scheduling real time services over time-varying wireless links in broad-band wireless networks where an Adaptive Modulation and Coding (AMC) scheme is applied in the physical layer in order to decrease the packet error rate. It is well known that a properly chosen modulation and coding scheme can increase error robustness in the physical layer. However, this is at the expense of higher system complexity and decreased channel efficiency. We present a novel Near Maximum Weighted Bipartite Matching (NMWBM) scheduling algorithm, which schedules real time services in accordance with delay bounds and physi-cal layer modulation and coding modes. Numerical re-sults set in the context of IEEE 802.16 networks show that NMWBM can improve system packet throughput and pro-vide higher channel efficiency compared to the existing Earliest Deadline First scheduling algorithm. NMWBM provides this improved performance while meeting delay bound and packet loss rate requirements of real time ser-vices in broadband wireless networks.

In this paper, the problem of scheduling multiple users sharing a time varying wireless channel is studied, in networks such as in 3G CDMA and IEEE 802.16. We propose a new generic Wireless Packet Scheduling Framework (WPSF), which takes into account not only the quality of service (QoS) requirements but also the wireless resource consumed. The framework is generic in the sense that it can be used with different resource constraints and QoS requirements depending on the traffic flow types. Subsequently, based on this framework a Minimum Rate and Channel Aware (MRCA) scheduling algorithm is presented. MRCA attempts to greedily enhance wireless channel efficiency by making use of multi-user channel quality diversity, while providing acceptable QoS in term of users' minimum rate constraints. Simulation results show the desirable properties identified in the algorithm. © 2006 IEEE.

In this paper, we propose a practically efficient Subcarrier Allocation scheme based on Lagrangian relaxation to solve the problem of subcarrier allocation in OFDMA wireless channels. The problem of subcarrier allocation is formulated into an Integer Programming (IP) problem, which is relaxed by replacing complicating constraints with Lagrange multipliers using Lagrangian Relaxation. A subgradient method is used to optimize the Lagrangian dual function and a heuristic is designed to obtain the feasible solution. Lagrangian Relaxation Subcarrier Allocation (LRSA) is proven to be of polynomial complexity and it provides bounds on the value of channel efficiency. Numerical results show that compared with other algorithms proposed in the literature, LRSA can result in a significant improvement in channel efficiency, while at the same time guaranteeing minimum data rates of users. ©2006 IEEE.

In this paper, we present a novel and efficient Subcarrire Allocation algorithm with Minimum Data RAte (SAMDRA) constraint for multiuers orthogonal frequency division multiple access (OFDMA) wireless networks. The proposed algorithm attempts to exploit both the time diversity and frequency diversity in the wireless channel. A concept of service expectation is used to indicate how users hope to be served and have their quality of service (QoS) guaranteed. The subcarrier allocation problem is decomposed into two stages. The first stage is to decide which user to be served based on the service expectation and channel quality of users. In the second stage, a sub-carrier is chosen for the current user in order to maxi-mize the average data rate. Numerical results demon-strate a significant improvement in the average date rate under the constraint of minimum data rate guarantee for users.

Unlike the previous multi-segment DRA designs that have a DRA of a lower permittivity above one or more thin segments of higher permittivity, the top DR in this antenna has a higher permittivity than the lower segment. Theoretical and experimental results exhibit good agreement.

Wood stressed skin panels (SSP) consist of multiple layers (panels and joists) assembled structurally together. Linear strain distribution is expected over the depth of the SSP section and full composite action is assumed. In 2002, a comprehensive investigation on SSP was launched at the University of Technology, Sydney. This research aims to provide a better understanding of SSP behaviours such as the serviceability and ultimate responses. During this research, a thorough review of the design methods was conducted and differences between the design procedures were identified. These differences are related to the way the composite and two-way actions are accounted for and the stresses are verified. This paper presents a review of design guidelines for estimating the section properties of SSP systems. It has a special focus on the tributary width because it corresponds to an important aspect of SSP composites. © 2006 by School of Engineering and Technology, Asian Institute of Technology.

In 2002 a large-scale investigation on stressed-skin panels (SSP) commenced at the University of Technology, Sydney. 27 full-scale specimens, manufactured according to Australian practices, were investigated under bending conditions with various load configurations. The tests also considered the effects of boundary conditions such as blocking and the influence of defects. The laboratory investigation comprised a series of non-destructive and destructive tests, which enabled identifying the serviceability and ultimate responses of SSP specimens. Procedures capable of predicting/simulating the behaviours of SSP systems have also been developed, including a finite element model (FEM) and a mathematical procedure. Both numerical approaches are capable of predicting serviceability responses of SSP structures accurately and have led to development of a recommended amendment to section 5 of AS 1720.1.

Auctions have recently commanded a lot of attention in the field of multi-agent systems. To be successful in open multi-attribute auctions, agents must be capable of adapting different strategies and tactics to their prevailing circumstances. This paper presents a software test-bed for studying autonomous bidding strategies in simulated auctions for procuring goods. It shows that agents' bidding strategy explore the attitudes and behaviors that help agents to manage dynamic assessment of alternative prices of goods given the different scenario conditions. Our agent also uses fuzzy techniques for the decision making: to make decisions about the outcome of auctions, and to alter the agent's bidding strategy in response to the different criteria and market conditions

A first step in developing and testing a robust affective multimodal system is to obtain or access data representing human multimodal expressive behaviour. Collected affect data has to be further annotated in order to become usable for the automated systems. Most of the existing studies of emotion or affect annotation are monomodal. Instead, in this paper, we explore how independent human observers annotate affect display from monomodal face data compared to bimodal face-and-body data. To this aim we collected visual affect data by recording the face and face-and-body simultaneously. We then conducted a survey by asking human observers to view and label the face and face-and-body recordings separately. The results obtained show that in general, viewing face-and-body simultaneously helps with resolving the ambiguity in annotating emotional behaviours.

Databases containing representative samples of human multi-modal expressive behavior are needed for the development of affect recognition systems. However, at present publicly-available databases exist mainly for single expressive modalities such as facial expressions, static and dynamic hand postures, and dynamic hand gestures. Only recently, a first bimodal affect database consisting of expressive face and upper-body display has been released. To foster development of affect recognition systems, this paper presents a comprehensive survey of the current state-of-the art in affect database creation from face and body display and elicits the requirements of an ideal multi-modal affect database

View description>>
In this study, both biological activated carbon (Powdered activated carbon (PAC) and granular activated carbon (GAC)) used in a submerged membrane â adsorption hybrid system (SMAHS) and a biological filtration system was evaluated for organic removal in wastewater reuse. The results indicated that the application of biological activated carbon in low strength wastewater treatment produced effluent of high quality that can be used for various reuse purposes. The adsorption and biological activity lead to a consistent effluent organic concentration over a long period of time. The submerged membrane adsorption hybrid system (SMAHS) was very effective in removing dissolved organic substances from the synthetic wastewater even with a low dosage of biological powdered activated carbon (BPAC). The adsorbed organics on the BPAC is biodegraded with time, and hence it creates sites for further adsorption of organics on the BPAC. The BPAC replacement in BPAC-MF reactor could stimulate both biological activity and adsorption, as well as optimize the operation of the hybrid system. Biological granular activated carbon (BGAC) consistently maintained an organic removal efficiency of 60% even with a shallow filter depth of 300 mm and after 42 days of operation. The growth of biomass onto BGAC experiments indicated that the attachment of biomass was quite consistent with about 85 mg/g GAC after 15 days in contact with synthetic wastewater. It was found that the amount of fixed biomass on filter media was proportionally related to biological dissolved oxygen consumption rate.

This paper addresses the problem of recovering epipolar geometry from spheres. Previous works have exploited epipolar tangencies induced by frontier points on the spheres for motion recovery. It will be shown in this paper that besides epipolar tangencies, N2 point features can be extracted from the apparent contours of the N spheres when N > 2. An algorithm for recovering the fundamental matrices from such point features and the epipolar tangencies from 3 or more spheres is developed, with the point features providing a homography over the view pairs and the epipolar tangencies determining the epipoles. In general, there will be two solutions to the locations of the epipoles. One of the solutions corresponds to the true camera configuration, while the other corresponds to a mirrored configuration. Several methods are proposed to select the right solution. Experiments on using 3 and 4 spheres demonstrate that our algorithm can be carried out easily and can achieve a high precision. © 2006 IEEE.

In the presented method, the dataset is firstly divided into several subsets and then K-means clustering is implemented in each subset. The clusters are classified by their group size. The centroids with small group size are eliminated and the rest centroids are used for SVR training. The relationships between the group sizes and the noisy clusters are discussed and simulations are also given. Results show that FDPP cleans most of the noises, preserves the useful statistical information and reduces the training samples. Most importantly, FDPP runs very fast and maintains the good regression performance of SVR.

Adoption of leading edge collaborative technologies requires considerable facilitation. There are two options to provide such support. The most common is by special human coordination roles. Another is by software agents. The paper describes a method to provide facilitation using software agents. It emphasizes the need to develop reusable agents and proposes an ontology as a basis for discovering such reusable agents. It then describes a framework for developing agents with increasing collaborative capabilities and describes a prototype implementation.

Spiral Architecture is a relatively new and powerful approach to machine vision system. The geometrical arrangement of pixels on Spiral architecture can be described in terms of a hexagonal grid. However, all the existing hardware for capturing image and for displaying image are produced based on rectangular architecture. It has become a serious problem affecting the advanced research on Spiral Architecture. In this paper, a new approach to mimicking Spiral Architecture is presented. This mimic Spiral Architecture almost retains image resolution and does not introduce distortion. Furthermore, images can be smoothly and easily transferred between the traditional square structure and this new hexagonal structure. In this paper, we also perform a fast way to locate hexagonal pixels. Another contribution in this paper is a novel construction of hexagonal pixels that are four times as big as the virtual hexagonal pixels. This construction of larger hexagonal pixels does not change the axes of symmetry, and does not create any spaces or overlaps between hexagons.

Image translation and rotation are becoming essential operations in many application areas such as image processing, computer graphics and pattern recognition. Conventional translation moves image from pixels to pixels and conventional rotation usually comprises of computation-intensive CORDIC operations. Traditionally, images are represented on a square pixel structure. In this paper, we perform reversible and fast image translation and rotation based on a hexagonal structure. An image represented on the hexagonal structure is a collection of hexagonal pixels of equal size. The hexagonal structure provides a more flexible and efficient way to perform image translation and rotation without losing image information. As there is not yet any available hardware for capturing image and for displaying image on a hexagonal structure, we apply a newly developed virtual hexagonal structure. The virtual hexagonal structure retains image resolution during the process of image transformations, and almost does not introduce distortion. Furthermore, images can be smoothly and easily transferred between the traditional square structure and the hexagonal structure.

Hexagonal structure is different from the traditional square structure for image representation. The geometrical arrangement of pixels on hexagonal structure can be described in terms of a hexagonal grid. Uniformly separating image into seven similar copies with a smaller scale has commonly been used for parallel and accurate image processing on hexagonal structure. However, all the existing hardware for capturing image and for displaying image are produced based on square architecture. It has become a serious problem affecting the advanced research based on hexagonal structure. Furthermore, the current techniques used for uniform separation of images on hexagonal structure do not coincide with the rectangular shape of images. This has been an obstacle in the use of hexagonal structure for image processing. In this paper, we briefly review a newly developed virtual hexagonal structure that is scalable. Based on this virtual structure, algorithms for uniform image separation are presented. The virtual hexagonal structure retains image resolution during the process of image separation, and does not introduce distortion. Furthermore, images can be smoothly and easily transferred between the traditional square structure and the hexagonal structure while the image shape is kept in rectangle

In the past few years, there has been significant advancement in localization and mapping using stereo cameras. Despite the recent successes, reliably generating an accurate geometric map of a large indoor area using stereo vision still poses significant challenges due to the accuracy and reliability of depth information especially with small baselines. Most stereo vision based applications presented to date have used medium to large baseline stereo cameras with Gaussian error models. Here we make an attempt to analyze the significance of errors in small baseline (usually <0.1m) stereo cameras and the validity of the Gaussian assumption used in the implementation of Kalman filter based SLAM algorithms. Sensor errors are analyzed through experimentations carried out in the form of a robotic mapping. Then we show that SLAM solutions based on the extended Kalman filter (EKF) could become inconsistent due to the nature of the observation models used

With limited dynamic range and poor noise performance, cameras still pose considerable challenges in the application of range sensors in the context of robotic navigation, especially in the implementation of simultaneous localisation and mapping (SLAM) with sparse features. This paper presents a combination of methods in solving the SLAM problem in a constricted indoor environment using small baseline stereo vision. Main contributions include a feature selection and tracking algorithm, a stereo noise filter, a robust feature validation algorithm and a multiple hypotheses adaptive window positioning method in 'closing the loop'. These methods take a novel approach in that information from the image processing and robotic navigation domains are used in tandem to augment each other. Experimental results including a real-time implementation in an office-like environment are also presented

This paper proposes a license plate detection algorithm using both global statistical features and local Haar-like features. Classifiers using global statistical features are constructed firstly through simple learning procedures. Using these classifiers, more than 70% of background area can be excluded from further training or detecting. Then the AdaBoost learning algorithm is used to build up the other classifiers based on selected local Haar-like features. Combining the classifiers using the global features and the local features, we obtain a cascade classifier. The classifiers based on global features decrease the complexity of the system. They are followed by the classifiers based on local Haar-like features, which makes the final classifier invariant to the brightness, color, size and position of license plates. The encouraging detection rate is achieved in the experiments

View description>>
Arbitrary ratio sampling rate conversion (SRC) structure using B-spline interpolation is proposed for software defined radio (SDR) in this paper. By combining SRC with SDR's transmitter/receiver filter, the constraint on SRC reconstruction filter can be relaxed, and an overall computational reduction can be achieved. The mixed-width B-spline is introduced so that both antiimaging and anti-aliasing requirements for SRC are satisfied. The passband droop introduced by the B-spline interpolation is compensated by a linear phase digital filter incorporated in the SRC structure so that the overall frequency response approaches the desired frequency response of the SDR's transmitter/receiver filter. To make the proposed SRC structure applicable in practice, the mixed-width B-spline is further converted into uni-width B-spline, and the simplified implementation of the uniwidth B-spline interpolation is also derived. A design example of the linear phase digital filter for the proposed SRC structure is given for an IEEE 802.11g wireless local area network (WLAN) SDR receiver, and the overall SRC complexity is analyzed.

Simple algorithms are also proposed for DC offset estimation and compensation. The analysis is confirmed by simulation using multiband OFDM specification for ultra-wideband application. © 2006 IEEE.

Wireless sensor networks have received a lot of attention in recent years both in the research community and in standards organizations. The emphasis of most sensor network research activities has been on the development of low cost and low power technologies for low bit rate applications. In this paper, we describe our work on ultra-wideband (UWB) sensor network technology targeted for video surveillance applications that require high immunity to noise, interference and jamming, high bit rate, and quality of service support. Such sensor networks are expected to find primary applications in the public safety and military fields. Our emphasis in this paper is on the design of the physical layer that can support such requirements and provide high end-to-end throughput when multi-hopping is used. ©2006 IEEE.

The infrastructure for the business and information exchange activities could be client-server, peer-To-peer (P2P), or mobile networks. In this paper we refer to 'peer' as an entity involved in a transaction. Trust between two interacting peers involved in an electronic transaction is a major issue that needs to be addressed in order to make the internet a safe medium for carrying out transactions. In this paper, we propose the aspects that can influence the trustworthiness assigned to the trusted peer. Furthermore we catalogue these factors into three classes and discuss the relationship between these factors.

Hence, a consideration for the trusting agent to analyze the risk in interacting with any probable trusted agent in order to decide whether to interact with it or not, is to determine the potential loss in its resources that may occur. In this paper, we will propose a methodology by which the trusting agent can determine beforehand the possible loss that could be incurred to it as a result of interacting with a probable trusted agent.

Decision making is a tough process. It involves dealing with a lot of uncertainty and projecting what the final outcome might be. Depending on the projection of the uncertain outcome, a decision has to be taken. In a peer-to-peer financial interaction, the trusting agent in order to analyze the Risk has to consider the possible likelihood of failure of the interaction and the possible consequences of failure to its resources involved in the interaction before concluding whether to interact with the probable trusted agent or not. Further it might also have to choose and decide on an agent to interact with from a set of probable trusted agents. In this paper we propose a Fuzzy Risk based decision making system that would assist the trusting agent to ease its decision making process.

In an e-commerce interaction carried out in a Peer-to-Peer environment it is rational for the trusting peer to analyze the Risk that could be involved in dealing with a trusted peer as there is a lack of central management in these type of interactions. Risk analysis can be done by assimilating recommendations from other peers if there is no previous interaction history between the trusting peer and the trusted peer. But the assimilated recommendations might be according to the criteria of the recommending peer with the trusted peer, and it is not necessary for the trusting peer to have the same criteria in its interaction with the trusted peer as that of the recommending peer even thought it is interacting in the same context. Further it might interact in a different time as that of the recommending peer. The Risk that was present in a particular context and at a particular time might not be the same at a different time. Hence in this paper we discuss the process of the trusting peer assimilating the recommendations from the recommending peers according to the context, criteria and time of its interaction in order to determine the Riskiness value of the trusted peer, which would help it considerably in decision making. © 2006 IEEE.

A comparison between realistic metamaterial (MTM) structures and theoretical, well-established dispersive material models, which predict the frequency dependence of the permittivity and the permeability, is performed in the present work. A number of highly subwavelength unit cells are analyzed that could potentially be used to achieve the epsilon-negative (ENG) parameters desired for the antenna applications studied in [1-4]. This presentation will give the effective permittivities and permeabilities of several simulated and measured ENG slabs and ENG cubical structures. For each of these classes of MTMs, it will be explained how the real and imaginary parts of the effective permittivities and permeabilities vary with frequency, how they are related to each other, and how low losses can be achieved. Several RF circuit-based and lumped element implementations to achieve the ε and μ values required for MTM-based efficient electrically small antenna systems have also been considered; those results will be shown in the presentation.

ABSTRACT: Native vegetation in Australia is becoming increasingly popular for stabilising railway corridors built over soft soils. A model previously developed to measure the rate of tree root water uptake and a computer model are used to investigate the effect of a wide range of soil, tree, and atmospheric parameters on partially saturated ground. First, sensitivity analysis is used to investigate the affect of different parameters on the maximum initial rate of root water uptake, and then a reference example is simulated using finite element analysis. The influence of parameters such as time, potential transpiration rate and its distribution factor, wilting point suction, the coefficient of permeability, and the distribution of root length density are studied. Soil suction and settlement was found to increase over time, with the effect being more significant in the first stages of transpiration. The most sensitive parameters are wilting point suction, the coefficient of saturation permeability at higher values, the rate of potential transpiration at lower values, and vertical root distribution when the coefficient is high.

Bioengineering aspects of native vegetation are currently, and rapidly, being evolved to improve soil stiffness, slope stabilisation, and erosion control. Apart from the reinforcement effect, tree roots establish sufficient matric suction to increase the shear strength and stiffness of the soil. This paper looks at the way, vegetation influences soil matric suction, shrinkage, and ground settlement. A mathematical model for the rate of root water uptake that considers ground conditions, type of vegetation and climatic parameters, has been developed. Based on this proposed model, the distribution of moisture and the matric suction profile adjacent to the tree are numerically analysed. The model formulation is based on the general effective stress theory of unsaturated soils. Field measurements taken from literature published previously are compared with the authors' numerical model. The predicted results calculated using the soil, plant, and atmospheric parameters contained in the numerical model, compared favourably with the measured results, justifying the assumptions upon which the model was developed.

A model developed for the rate of tree root water uptake is applied numerically based on finite element analysis, to investigate the effects of the soil, tree and atmospheric parameters on the ground behaviour. The influences of potential transpiration rate, permeability coefficient, and the maximum root length density are studied and quantified. Although the rate of transpiration increases the soil matric suction and the ground settlement, permeability (saturated) decreases the matric suction generated and the corresponding settlement. The maximum root density also affects the change in peak matric suction as demonstrated in the paper.

Railway ballast deforms and degrades progressively under heavy cyclic loading. Ballast degradation is influenced by several factors including the amplitude and number of load cycles, gradation of aggregates, track confining pressure, angularity and fracture strength of individual grains. The degraded ballast is usually cleaned on track, otherwise, fully or partially replaced by fresh ballast, depending on the track settlement and current density. The use of composite geosynthetics at the bottom of recycled ballast layer is highly desirable to serve the functions of both drainage and separation of ballast from subballast. Construction of the rail track also requires appropriate improvement of the subgrade soils to achieve an adequately stiff surface layer prior to placing the ballast and subballast. Based on extensive research at University of Wollongong, it is found that the gradation of ballast plays a significant role in the strength, deformation, degradation, stability and drainage of rail tracks. Results from large-scale triaxial testing indicate that a small increase in confining pressure improves track stability with less ballast degradation. Bonded geogrids-geotextiles also decrease differential settlements of tracks, ballast degradation and lateral movement, and the risk of subgrade pumping. Stabilization of soft subgrade soils is also essential for improving the overall stability of track and to reduce the differential settlement during the operation of trains. This paper also highlights the effectiveness of using prefabricated vertical drains (PVDs) for improving the behavior of soft formations underlying rail tracks. Copyright ASCE 2006.

The new structure has many degrees of freedom for close-fit designs.

In this paper, a novel colour edge cooccurrence histogram (CECH) method is proposed to match images by measuring similarities between their CECH histograms. Unlike the previous colour edge cooccurrence histogram proposed by Crandall and Luo (2004 ) we only investigate those pixels which are located at the two sides of edge points in their gradient direction lines and at a distance away from the edge points. When measuring similarities between two CECH histograms, a newly proposed Gaussian weighted histogram intersection (GWHI) method is extended for this purpose. Both identical colour pairs and similar colour pairs are taken into account in our algorithm, and the weights are decided by the larger distance between two colour pairs involved in matching. The proposed algorithm is tested for matching vehicle number plate images captured under various illumination conditions. Experimental results demonstrate that the proposed algorithm can be used to compare images in real-time, and is robust to illumination variations and insensitive to the model images selected.

Firstly, the magnetic curve of ferromagnetic material is smoothed by a BPNN. Secondly, this paper deduces the formula of magnetic force based on the local Jacobian derivative method and the magnetic vector potential. Thirdly, the determination of the optimal BPNN structures and learning times is introduced. At last, a dynamic model of SRM based on BPNNs is constructed. The validity of the model is proved by comparing the simulation results with the experimental results. © 2006 IEEE.

Electroencephalographic (EEG) analysis has been widely adopted for the monitoring of cognitive state changes and sleep stages because abundant information in EEG recording reflects changes in drowsiness, arousal, sleep, and attention, etc. In this study, Micro-Electro-Mechanical Systems (MEMS) based silicon spiked electrode array, namely dry electrodes, are fabricated and characterized to bring EEG monitoring to the operational workplaces without requiring conductive paste or scalp preparation. An isotropic/anisotropic reactive ion etching with inductive coupled plasma (RIE-ICP) micromachining fabrication process was developed to manufacture the needle-like micro probes to pierce the stratum corneum of skin and obtain superior electrically conducting characteristics. This article reports a series of prosperity testing and evaluations of continuous EEG recordings. Our results suggest that the dry electrodes have advantages in electrode-skin interface impedance, signal intensity and size over the conventional (wet) electrodes. In addition, we also developed an EEG-based drowsiness estimation system that consists of the dry-electrode array, power spectrum estimation, Principal Component Analysis (PCA)-based EEG signal analysis, and multivariate linear regression to estimate driver's drowsiness level in a virtual-reality-based dynamic driving simulator to demonstrate the potential applications of the MEMS electrodes in operational environments. ©2006 IEEE.

This paper describes a driver fatigue detection system using an Artificial Neural Network (ANN). Using electroencephalogram (EEG) data sampled from 20 professional truck drivers and 35 non professional drivers, the time domain data are processed into alpha, beta, delta and theta bands and then presented to the neural network to detect the onset of driver fatigue. The neural network uses a training optimization technique called the Magnified Gradient Function (MGF).

This paper describes a driver fatigue detection system using an artificial neural network (ANN). Using electroencephalogram (EEG) data sampled from 20 professional truck drivers and 35 non professional drivers, the time domain data are processed into alpha, beta, delta and theta bands and then presented to the neural network to detect the onset of driver fatigue. The neural network uses a training optimization technique called the magnified gradient function (MGF). This technique reduces the time required for training by modifying the standard back propagation (SBP) algorithm. The MGF is shown to classify professional driver fatigue with 81.49% accuracy (80.53% sensitivity, 82.44% specificity) and non-professional driver fatigue with 83.06% accuracy (84.04% sensitivity and 82.08% specificity).

This paper presents the lessons learnt during the analysis of the corporate databases developed by IBM Global Services (Australia). IBM is rated as CMM level 5. Following CMM level 4 and above practices, IBM designed several software metrics databases with associated data collection and reporting systems to manage its corporate goals. However, IBM quality staff believed the data were not as useful as they had expected. NICTA staff undertook a review of IBM's statistical process control procedures and found problems with the databases mainly due to a lack of links between the different data tables. Such problems might be avoided by using M P variant of the GQM paradigm to define a hierarchy of goals, with project goals at the lowest level, then process goals and corporate goals at the highest level. We propose using E-R models to identify problems with existing databases and to design databases once goals have been defined. Copyright 2006 ACM. 3

Multimodal sensor registration and calibration are crucially important aspects in distributed sensor fusion. Unknown relationships of sensors and joint probability distribution between sensory signals make the sensor fusion nontrivial. In this paper, we adopt a Mutual Information (MI) based approach for sensor registration and calibration. It is based on unsupervised learning of a nonparametric sensing model by maximizing mutual information between signal streams. Experiments were carried out in an office like environment with two laser sensors capturing arbitrarily moving people. Attributes of the moving targets are used. Problems due to target occlusions are alleviated by the multiple model tracker. The registration and calibration methodology does not require any artificially generated patterns or motions unlike other calibration methodologies

This paper applies a meta-heuristic based Ant Colony Optimization (ACO) technique for simultaneous task allocation and path planning of Automated Guided Vehicles (AGV) in material handling. ACO algorithm allocates tasks to AGVs based on collision free path obtained by a proposed path and motion planning algorithm. The validity of this approach is investigated by applying it to different task and AGV combinations which have different initial settings. For small combinations, i.e. small number of tasks and vehicles, the quality of the ACO solution is compared against the optimal results obtained from exhaustive search mechanism. This approach has shown near optimal results. For larger combinations, ACO solutions are compared with Simulated Annealing algorithm which is another commonly used meta-heuristic approach. The results show that ACO solutions have slightly better performance than that of Simulated Annealing algorithm. © 2006 IEEE.

This paper addresses the enhancement of the contrast of gray-level digital images while preserving the mean image intensity, thus, providing better viewing consistency and effectiveness. The contrast enhancement is achieved by maximizing the information content carried in the image with a continuous intensity transform function and the mean image intensity is preserved, by using the gamma-correction approach. Since the contrast enhancement and intensity preservation are contradicting, a multi-objective particle swarm optimization (MPSO) algorithm is developed to resolve this trade-off. Benchmark images, street senses and skyline images are included to illustrate the effectiveness of the proposed approach

The effects of randomness of control coefficients in Particle Swarm Optimization (PSO) are investigated through empirical studies. The PSO is viewed as a method to solve a coverage problem in the solution space when the global-best particle is reported as the solution. Randomness of the control coefficients, therefore, plays a crucial role in providing an efficient and effective algorithm. Comparisons of performances are made between the uniform and Gaussian distributed random coefficients in adjusting particle velocities. Alternative strategies are also tested, they include: i) pre-assigned randomness through the iterations, ii) selective hybrid random adjustment based on the fitness of the particles. Furthermore, the effect of velocity momentum factor is compared between a constant and random momentum. Numerical results show that performances of the proposed variations are comparable to the conventional implementation for simple test functions. However, enhanced performances using the selective and hybrid strategy are observed for complicate functions. ©2006 IEEE.

To date no-study has tested the reproducibility of electroencephalography (EEG) changes that occur during driver fatigue. For the EEG changes to be useful in the development of a fatigue sensing and countermeasure device the EEG response during each onset period of fatigue in individuals needs to be reproducible. The aim of the present study was to investigate the reproducibility of the EEG changes during fatigue in professional drivers in order to identify the feasibility of the EEG measure for a fatigue sensor. Twenty professional drivers were assessed during two separate sessions of a driver simulator task. EEG, eye activity and behavioural measurements of fatigue were obtained during the driving task. The results showed significant reproducibility for the EEG slow wave activity (r >0.95) and fast wave activity (r >0.60). The results have promising implications for the development of an EEG based fatigue-sensing device. The EEG changes during fatigue were reproducible and therefore, appear to be a promising neurophysiological measure, which can be incorporated into an on-line fatigue sensor.

We consider a search for a target moving within a known indoor environment partitioned into interconnected regions of varying sizes. The knowledge of target location is described as a probability distribution over the regions, and the searcher can only move from one region to another as the structure allows. The objective is to find a feasible path through the regions that maximizes the probability of locating the target within fixed time. This problem generalizes the existing optimal searcher path problem (OSP) by additionally stipulating a minimum amount of time that a finite-speed searcher must spend to travel through a region before reaching the next. We propose a technique to obtain the upper bound of detection for solving the problem in a branch and bound framework. Comparisons show that the technique is also superior to known bounding methods for the original optimal searcher path problem

Semi-distributed hydrological models generally have the advantages of short calculation times, comparative low calibration needs and high model efficiency, but lack the ability to consider localization effects of land use change. A regionalisation of these models allows a sensitivity analysis of the localization effects. HBV-D, a conceptual hydrological model is used in this study. The regionalization for the German watershed Parthe (∼317 km 2) is coded in the framework of SME (spatial modeling environment) which allows a fast grid based regionalization of the model. Additional complexity at the finer scale is handled by downscaling of calibration parameters fromthe semi-distributedmodel by using auxiliary information (soil, relief). This allows a better representation of the heterogeneity in the watersheds without the need of grappling with hundreds of calibration parameters. A Monte-Carlo analysis is used to simulate the effects of the different spatial pattern of land use changes on discharge. This allows a better forecasting of land use change effects and can be used to generate uncertainty estimates for existing semi-distributed models. We focus here on the following major questions: 1. how can we downscale the calibration parameters from the semi-distributed model to the distributed model, 2. how do downscaling approaches differ, 3. how does land use composition and configuration influence discharge and 4. how do these results depend on catchment characteristics?

In this paper, we expand the idea of spreading the transmitted symbols in OFDM systems by unitary spreading matrices based on the rotated Hadamard or rotated Discrete Fourier Transform (DFT) matrices proposed in the literature to apply to Space-Time Coded Multiple-Input Multiple-Output OFDM (STC-MIMO-OFDM) systems. We refer the resulting systems to as STC-MIMO Block Spread OFDM (STC-MIMO-BOFDM) systems. In the proposed systems, a multi-dimensional diversity, including time, frequency, space and modulation diversities, can be used, resulting in better bit error performance in frequency selective Rayleigh fading channels compared to the conventional OFDM systems with or without STCs. Simulations carried out with the Alamouti code confirm the advantage of the proposed STC-MIMO-BOFDM systems. © 2006 IEEE.

The response surface method (RSM) is applied in the parameter optimization of nonlinear stress control tubes in power cable terminations. A local approximation method, called moving least square method (MLSM), is adopted to reduce the approximation errors. The electric field intensity is calculated by the transient finite element method. A comparison of the parameters before and after optimization reveals that the RSM is constructed efficiently and accurately by using the MLSM. © 2006 IEEE.

Peer-to-peer (P2P) technologies developed rapidly in different directions with various applications and routing mechanisms. However, the lack of standardization in functional architectures of the P2P systems makes their performances far from optimal. This trend also restricts the interoperability amongst the systems, and limits the exploitation of the edge-Internet resources and tangible benefits for Internet users. Inspired by the TCP/IP model, this paper introduces PARM: a physically-aware reference model for overlay internetworking. PARM is a layered model that enables a more modular communications approach to solve P2P problems and to optimize systems more efficiently. Simulation results indicate that PARM helps to produce better performance overlays with desirable features such as decentralization, self-organization, and minimal delay penalty.

Studies which I carried out recently of users of digital music players revealed that the element of randomness plays a role in influencing the user experience (UX). Apart from being generally positive, some users even report rich experiences such as serendipity. I propose a longitudinal study to further explicate the phenomena. In doing so, I aim to produce a theoretical framework which will provide a richer characterization of the randomness-influenced UX. This will add to our understanding of UX and may serve to inform designers of interactive systems on how randomness can be used as an innovative design resource for supporting rich and novel UX.

Active SLAM poses the challenge for an autonomous robot to plan efficient paths simultaneous to the SLAM process. The uncertainties of the robot, map and sensor measurements, and the dynamic and motion constraints need to be considered in the planning process. In this paper, the active SLAM problem is formulated as an optimal trajectory planning problem. A novel technique is introduced that utilises an attractor combined with local planning strategies such as model predictive control (a.k.a. receding horizon) to solve this problem. An attractor provides high level task intentions and incorporates global information about the environment for the local planner, thereby eliminating the need for costly global planning with longer horizons. It is demonstrated that trajectory planning with an attractor results in improved performance over systems that have local planning alone

Multilevel converters uses a large amount of semiconductors. This allows to reconfigurate the converter to work even on internal fault condition. This paper presents a method to detect faulty cells in a cascaded multicell converter requiring just one voltage measurement per output phase. The method is based on high frequency harmonic analysis, using a dynamic prediction of their behavior, avoiding false detection on transients while keeps the precision under fault events. Once the faulty cell is detected, it can be shortcircuited allowing the converter to keep working according to previously reported techniques. © 2006 IEEE.

This paper addresses the problem of designing a decentralized control of interconnected power systems, with OLTC and SVCs, under large changes in real and reactive loads that cause large structural changes in the system model. In addition to this, small changes in load are regulated by small disturbance controllers whose gains are adjusted for variations in power system model due to large changes in loads. The only feedback needed by subsystem controllers is the state of the subsystem itself. The design is carried out within a large-scale Markov jump parameter systems framework. In this paper, unlike other control schemes, OLTC transformers are used to damp power-angle oscillations. Simulation results are presented to demonstrate the performance of the designed controller.

A guaranteed upper bound on robust performance is also obtained.

Representing and reasoning about spatial information is important in artificial intelligence and geographical information science. Relations between spatial entities are the most important kind of spatial information. Most current formalisms of spatial relations focus on one single aspect of space. This contrasts sharply with real world applications, where several aspects are usually involved together. This paper proposes a qualitative calculus that combines a simple directional relation model with the well-known topological RCC5 model. We show by construction that the consistency of atomic networks can be decided in polynomial time.

Using additional store-checkpoinsts (SCPs) and compare-checkpoints (CCPs), we present an adaptive checkpointing for double modular redundancy (DMR) in this paper. The proposed approach can dynamically adjust the checkpoint intervals. We also design methods to calculate the optimal numbers of checkpoints, which can minimize the average execution time of tasks. Further, the adaptive checkpointing is combined with the DVS (dynamic voltage scaling) scheme to achieve energy reduction. Simulation results show that, compared with the previous methods, the proposed approach significantly increases the likelihood of timely task completion and reduces energy consumption in the presence of faults.

View description>>
This paper proposes a new algorithm method for detection and compensation of backlight images. The proposed technique attacks the weaknesses of conventional backlight image processing methods, such as over-saturation and diminished contrast. This proposed algorithm consists of two operational phases, the detection phase and the compensation phase. In the detection phase, we use the spatial position characteristic and the histogram of backlight images to obtain two image indices which can determine the backlight degree of an image. The fuzzy inference method is then used to integrate these two indices into a final backlight index which determines the final backlight degree of an image more precisely. The compensation phase is used to solve the over-saturation problem which usually exists in conventional image compensation methods. In this phase, we propose the adaptive cubic curve method to compensate and enhance the brightness of backlight images. The luminance of a backlight image is adjusted according to the cubic curve equation which adapts dynamically according to the backlight degree indicated by the backlight index estimated in the detection phase. The performance of the proposed technique was tested against 300 backlight images covering a variety of backlight conditions and degrees. A comparison of the results of previous experiments clearly shows the superiority of our proposed technique in solving over-saturation and backlight detection problems. © 2006 TFSA.

This paper is to investigate a novel design for local motion vectors (LMVs) of image sequences, which are often used in a digital image stabilization (IS) system. The IS technique removes unwanted shaking phenomenon in image sequences captured by hand-held camcorders. It includes two main parts such as motion estimation and compensation.

The objective of this paper is to investigate a novel design for local motion vectors (LMVs) of image sequences, which are often used in a digital image stabilization (IS) system. The IS technique removes unwanted shaking phenomenon in image sequences captured by hand-held camcorders. It includes two main parts such as motion estimation and compensation. Most of computation power occurs in the part of motion estimation. In order to reduce this complexity, an idea, which integrates an adaptive-threshold method and cellular neural networks (CNN) architecture, is designed to improve this problem.

In this paper, we present a real-time multi-objects tracking system which can detect various types of moving objects in image sequences of traffic video obtained from a stationary video camera. Using the adaptive background reconstruction technique can effectively handle with environmental changes and obtain good results of objects extraction. Besides, we introduce a robust region- and feature-based tracking algorithm with plentiful features to track correct objects continuously. After tracking objects successfully, we can analyze the tracked objects' properties and recognize their behavior for extracting some useful traffic parameters. According to the structure of our proposed algorithms, we implemented a tracking system including the functions of objects classification and accident prediction. Experiments were conducted on real-life traffic video of some intersection and testing datasets of other surveillance research. The results proved the algorithms we proposed achieved robust segmentation of moving objects and successful tracking with objects occlusion or splitting events. The implemented system also extracted useful traffic parameters. © 2006 IEEE.

Driving safely has received increasing attention of the publics due to the growing number of traffic accidents that the driver's driving style is highly correlated to many accidents. The purpose of this study is to investigate the relationship between driver's driving style and driver's ERP response. In our research, a virtual reality (VR) driving environment is developed to provide stimuli to subjects. Independent component analysis (ICA) is used to decompose the electroencephalogram (EEG) data. The power spectrum analysis of ICA components and correlation analysis are employed to investigate the EEG activities related to driving style. Experimental results demonstrate that we may classify the drivers into aggressive or gentle styles based on the observed ERP difference corresponding to the proposed unexpected obstacle dodging tasks. © 2006 IEEE.

The public security has become an important issue in recent years, especially, the safe manipulation and control of vehicles in preventing the growing number of traffic accident fatalities. Accidents caused by drivers' drowsiness have a high fatality rate due to the decline of drivers' abilities in perception, recognition, and vehicle control abilities while sleepy. Preventing such an accident requires a technique for detecting, estimating, and predicting the level of alertness of a driver and a mechanism to maintain the driver's maximum performance of driving. The ICAFNN is a fuzzy neural network (FNN) capable of parameter self-adapting and structure selfconstructing to acquire a small number of fuzzy rules for interpreting the embedded knowledge of a system from the given training data set. Our experiments show that the ICAFNN can achieve significant improvements in the accuracy of drowsiness estimation compared with our previous works. © 2006 IEEE.

In this paper, we propose a cost-effective and low-power 64-point fast Fourier transform (FFT)/inverse FFT (IFFT) architecture and chip adopting the retrenched 8-point FFT/IFFT (R8-FFT) unit and an efficient data-swapping method based output buffer unit The whole chip systematic performance concerning about the area, power, latency and pending cycles for the application of IEEE 802.11a WLAN standard has been analyzed. The proposed R8-FFT unit utilizing the symmetry property of the matrix decomposition achieves half computation-complexity and less power consumption compared with the recently proposed FFT/IFFT designs. On the other hand, applying the proposed data-swapping method, a low-cost and low-power output buffer can be obtained. So as to further increase system performance, we propose one scheme: the multiplication-afler-write (MAW) method. Applying MA W method with R8-FFT unit, the resulting FFT/IFFT design not only leads to the balancing pending cycle, but also abbreviating computation latency to 8 clock cycles. Consequently, adopting the above proposed two units and one scheme, the whole chip consumes 22.36mW under 1.2V@20 MHz in TSMC 0.13 1P8M CMOS process. © 2006 IEEE.

A new e-Learning system is proposed in this paper. It is called NEXUS (Next-generation Extra University-education System). NEXUS is an on-line learning system that is focus on undergraduate course. This system includes virtual lectures, question confirm pages, application sharing, keywords and reference data sharing and cooperative discussion tool. The feature of NEXUS is based on cooperative discussion tool. Wherever students are studying, they can discuss together, have a net meeting at the same time via NEXUS. The procedure is not difficult that even students who are not familiar with computer knowledge can use this system simply. In addition, another function that video-streaming data is converted to text data by the technology of Speech Recognition is developing. That means students will be able to pick up any scene of video they want to review from researching by text data. © 2006 IEEE.

This paper reports on the authors use of the SOLO taxonomy to describe differences in the way students and educators solve small code reading exercises. SOLO is a general educational taxonomy, and has not previously been applied to the study of how novice programmers manifest their understanding of code. Data was collected in the form of written and think-aloud responses from students (novices) and educators (experts), using exam questions. During analysis, the responses were mapped to the different levels of the SOLO taxonomy. From think-aloud responses, the authors found that educators tended to manifest a SOLO relational response on small reading problems, whereas students tended to manifest a multistructural response. These results are consistent with the literature on the psychology of programming, but the work in this paper extends on these findings by analyzing the design of exam questions.

A force field (F2) based multi-robot collaboration method is presented in this paper. In this method, a virtual force field is generated for every moving robot and continuously changing based on the robot status including its traveling speed, dimension, priority, location and environment, etc. The interactions among robots' force fields and obstacles provide a natural way for collision avoidance and collaboration while robots are on their way to goals. In this paper, the definition of reaction force direction is modified to reduce robot orientation oscillations which occur when a robot approaches obstacles or other robots. Then the influence of task priority on motion planning and the problem of deadlock in multi-robot cases are discussed. Simulations in a real indoor environment were carried out and demonstrated the feasibility and effectiveness of this method

With the increasing applications of fully autonomous vehicles, efficient motion coordination of multi-autonomous vehicles becomes a very important problem as it significantly affects the productivity. This problem is even harder to solve with the increases of the number of autonomous vehicles employed in a dynamic changing environment and constraints to vehicle movement. This paper presents a simultaneous path and motion planning (SiPaMoP) approach to coordinate motions of multi-autonomous vehicles in dynamic and strictly constrained environments. This approach integrates the path planning, collision avoidance and motion planning into a comprehensive model, which has so far not attracted a lot of attention in the academic literature, and optimizes vehicles' path and speed to minimize the completion time of a set of tasks. Simulation results demonstrated that this approach can effectively coordinate the motion of a team of vehicles, and solve the problems of traffic congestion and collision under various traffic conditions. © 2006 IEEE.

As agile methodologies are being adopted by increasing number of organizations, there is a greater need to understand its value. This study attempts to explain the value of Agile Methodologies by introducing a new economic analytical model and using simulation techniques. The results show that uncertainty level has a strong effect of the level of process effectiveness. Lower level of uncertainty is associated with high levels of project effectiveness regardless the level of pre-committed project costs and project duration. When the level of uncertainty is high, the level of process effectiveness is low regardless of the level of pre-committed project costs and project duration; and, the process effectiveness declines at a fast rate with longer project duration and/or higher level of pre-committed project costs. Agile methodology's value-adding comes from its core values of effective communication, and starting from small for shorter duration. It is suitable for projects with high levels of uncertainty. In contrast, the plan driven approach, tends to increase project duration, pre-committed project costs and fails to reduce the level of uncertainty. It is only suitable for projects with low level of uncertainty. © 2006. Li Liu, Xiaoying Kong and Jing Chen.

The next generation wireless networking (4G) is envisioned as a convergence of different wireless access technologies with diverse levels of performance. Vertical handoff (VHO) is the basic requirement for convergence of different access technologies and has received tremendous attention from the academia and industry all over the world. During the VHO procedure, handoff decision is the most important step that affects the normal working of communication. In this paper, we propose a novel vertical handoff decision algorithm, Self-Adaptive VHO Algorithm (SAVA), and compare its performance with conventional algorithms. SAVA synthetically considers the long term movement region and short term movement trend of mobile hosts, and achieves a good integrative handoff performance. © 2006 IEEE.

In recent years, many research works have focused on vertical handoff (VHO) decision algorithms. However, evaluation scenarios in different papers are often quite different and there is no consensus on how to evaluate performance of VHO algorithms. In this paper, we address this important issue by proposing an approach for systematic and thorough performance evaluation of VHO algorithms. Firstly we define the evaluation criteria for VHO with two metrics: matching ratio and average ping-pong number. Subsequently we analyze the general movement characteristics of mobile hosts and identify a set of novel performance evaluation models for VHO algorithms. Equipped with these models and evaluation criteria, we evaluate and analyze two types of decision algorithms: hysteresis based and dwelling-timer based algorithms. The results show a good match between simulation and analytical results. © 2006 IEEE.

A zero-pad can be used with orthogonal frequency division multiplexing (OFDM) for low-complexity robustness against multipath interference. In this paper, we use adaptive overlap-add (OLA) equalization for improvements of up to 1 dB when used with multi-band OFDM (MB-OFDM) ultra-wideband. A theoretical model that relates the size of OLA window to post-equalizer signal-to-noise ratio is derived. An approximating algorithm is then developed that is suitable for low-complexity implementation, with Monte Carlo simulations used to quantify the performance improvements. We conclude that adaptive OLA equalization is computationally simple and can be implemented while remaining fully compliant with the MB-OFDM standard. © 2006 IEEE.

In this paper, we design complementary codesets that significantly improve the quality of channel estimation in orthogonal frequency division multiplexing (OFDM) communication systems, with a focus on the recent MB-OFDM ultrawideband (UWB) standard. The proposed time-domain OFDM channel estimation technique incurs only a nominal increase in computational complexity and is able to be readily retrofitted into the existing MB-OFDM standard. The underlying complementary codesets, found via an evolutionary algorithm, combine with the existing preamble synchronization sequences to yield asymptotically ideal auto-correlation functions (ACFs). We show how improvements exceeding 1 dB can be achieved in end-to-end packet error rate relative to conventional zero-forcing OFDM equalization. © 2006 IEEE.

In this paper, a novel two-stage noise removal algorithm to deal with salt-pepper impulse noise is proposed. In the first stage, the decision-based recursive adaptive noise-exclusive median filter is applied to remove the noise cleanly and to keep the uncorrupted information as well as possible. In the second stage, the fuzzy decision rules inspired by human visual system (HVS) are proposed to classify image pixels into human perception sensitive class and non-sensitive class. A neural network is proposed to compensate the sensitive regions for image quality enhancement. According to the experimental results, the proposed method is superior to conventional methods in perceptual image quality as well as the clarity and the smoothness in edge regions of the resultant images.

Through conducting a survey customer data is collected as evidences for inference of the relationships among the factors described in the model. After creating a graphical structure, this study calculates conditional probability distribution among these factors, and then conducts inference by using the Junction-tree algorithm. A set of useful findings has been obtained for customer online shopping behaviours and their requirements with motivations.

This paper explores the size and value effect in influencing performance of individual companies using backpropagation neural networks. According to existing theory, companies with small market capitalization and high book to market ratios have a tendency to perform better in the future. Data from over 300 Australian Stock Exchange listed companies between 2000-2004 is examined and a neural network is trained to predict company performance based on market capitalization, book to market ratio, beta and standard deviation. Evidence for the value effect was found over longer time periods but there was less for the size effect. Poor company performance was also observed to be correlated with high risk. © 2006, Australian Computer Society, Inc.

Lack of high-level usability awareness often leads the e-business communities to a missing relative assessment of capability of collaborative businesses effectively in terms of achieving strategic and competitive advantages. In this paper, we propose a new strategic framework for an evolutionary Collaborative Space of Opportunities (CSO) whilst using a Telecollaboration (TC) business system during Enterprise Resource Planning (EPP) training. Initially, we apply Callos's General System Theory (GST) with the description of logistics elements of this framework. Next, we provide a business logistics management perspective within CSO, addressing organizational effectiveness, technology integration control efficiency and user satisfaction. This includes formation of co-evolutionary loops to induce the apparent system usability objectives to explore the emergence of business logistics portfolios and technology integration control profiles of the users. We then describe our proposed Collaborative Space of Opportunities Matrices (CSOM) to analyse the apparent usability alternatives in this multi-criteria decision making environment. In this context, we apply the general form of Saaty's Analytic Hierarchy Process (AHP) to demonstrate how these matrices could be used as a generic elicitation tool. It is here, we provide a set of systematic, explicit, rigorous and robust reinforcement mechanisms for quantifying and prioritizing the Decision elements (De) involved. We assume that the exposition on AHP has the Business process Re-engineering (BPR) effect to measure and synthesize the often conflicting apparent usability objectives and alternatives of a TC business system during EPP training.

Teaching Telecoms Network Mgmt can be very challenging. The aspiration is to give our students an end to end view of the Telecom Service Provider domain. The emphasis is on the understanding of the Service Provider's(SP) needs, exploring technology solution sets, and developing an integrated approach to Network Mgmt. The background knowledge required to appreciate the course content is wide. The use of an Information Model (IM) has been found to be useful in giving the students the understanding of the interaction of the components within a SP as well as the end to envision while allowing to appreciate the detail when required. This paper details our course, its content and usage of the TMF's IM to facilitate the teaching of the course. Our paper discusses one method, usage of developing industry Information Models (IM), as a method we have employed to overcome this. We discuss how we have structured the content, assessments tasks and assessment reviews to give a unified view into the course goals. ©2006 IEEE.

Recent years have seen an increasing number of computer vision applications focusing on humans as their objects of interest. Such applications include video surveillance, domotics, multimedia semantic annotation and indexing, human-computer interfaces, affective computing, just to cite a few. What exactly are their "objects of interest"? A broad range of human-related features: motion, gestures, actions, interactions, activities, attitudes, behaviours, identity. This keynote will offer a survey of this field and present some current work from the speaker and his collaborators in the areas of emotion recognition and people tracking within camera networks. © 2006 IEEE.

Because of the high birefringence of the PCF Hi-Bi, the fibre length required to make such a device was an order of magnitude lower than if conventional Hi-Bi is employed. The residual degree of polarisation was found to be as low as 0.25%.

Modern simulations and games have limited capabilities for simulated characters to interact with each other and with humans in rich, meaningful ways. Although significant achievements have been made in developing human behavior models (HBMs) that are able to control a single simulated entity (or a single group of simulated entities), a limiting factor is the inability of HBMs developed by different groups to interact with each other. We present an architecture and multi-level message framework for enabling HBMs to communicate with each other about their actions and their intents, and describe the results of our crowd control demonstration system which applied it to allow three distinct HBMs to interoperate within a single training-oriented simulation. Our hope is that this will encourage the development of standards for interoperability among HBMs which will lead to the development of richer training and analysis simulations.

Integrated assessment models, decision support systems (DSS) and Geographic Information Systems (GIS) are examples of a growing number of computer-based tools designed to provide scientific decision and information support to people within environmental management and policy organizations. It is recognized that end-user organizations are often not as receptive to using such tools as desired but that little research has been done to uncover and understand the reasons why. As part of the process to understand what tools are used and why, and conversely what tools are not used and why, this paper presents some views on the issues involved. No claim is made regarding the completeness of the issues covered, rather the purpose of the paper is to instigate discussion about how to improve tool design practices in such a way as to benefit environmental management and policy. Conflict between the aims of tool designers to develop usable and useful tools which also contain some degree of technological innovation is highlighted as a potential cause of problems. A call for clarity of purpose in tool design is made to make it clearer both to the designer and the client organization what the main aim of the design process is as a means of uncovering mismatches in expectation. Further, a call is made for designers to move from a technology-push to a demand-pull perspective as a necessary step towards designing more appropriate tools. A range of social dimensions of relevance to tool design are also discussed including the need to involve clients and stakeholders early in the design process, whether a model should present a simple and engaging story and to what extent good science can be implemented through the use of computer models, and the need to build trust between tool designers and tool users as a necessary part of making tools useful.

From a personalized media point of view, many users favor a flexible tool to quickly browse the affective content in a video. Such affective content may cause audiences' strong reactions or special emotional experiences, such as anger, sadness, fear, joy and love. This paper attempt to extract affective content for digital videos by analyzing the subtitle files of DVD/DivX videos and utilizing audio event to assist affective content detection. Firstly, video are segmented by dialogue script partition. Compared to traditional video shot, video segmented by scripts is not affected by camera changes and shooting angles and easy to include video segments with compact content. Secondly, emotion-related vocabularies in video script are detected to locate affective video content. Using script to directly access video content avoids complex video analysis. Thirdly, audio event detection is utilized to assist affective content detection. Compared with traditional video semantic analysis, affective content analysis puts much more emphasis on the audience's reactions and emotions. Initial experiments are carried on sitcom videos because its simple video structure provides useful domain knowledge. The experimental results demonstrate that subtitle file analysis and audio event detection provides effective and efficient clues to determine the emotional content of the videos. © 2006 IEEE.

The main contribution of this paper is a novel stereo-based algorithm which serves as a tool to examine the viability of stereo vision solutions to the simultaneous localisation and mapping (SLAM) for large indoor environments. Using features extracted from the scale invariant feature transform (SIFT) and depth maps from a small vision system (SVS) stereo head, an extended Kalman filter (EKF) based SLAM algorithm, that allows the independent use of information relating to depth and bearing, is developed. By means of a map pruning strategy for managing the computational cost, it is demonstrated that statistically consistent location estimates can be generated for a small (6 m times 6 m) structured office environment, and in a robotics search and rescue arena of similar size. It is shown that in a larger office environment, the proposed algorithm generates location estimates which are topologically correct, but statistically inconsistent. A discussion on the possible reasons for the inconsistency is presented. The paper highlights that, despite recent advances, building accurate geometric maps of large environments with vision only sensing is still a challenging task

The thermo-mechanical robustness of interconnect structures is a key reliability concern for integrated circuits. The introduction of new low dielectric constant (low-k) materials with deteriorated mechanical strength (i.e., Young Modulus decreases exponentially with film porosity, which is needed to lower the k value of the dielectric materials) to meet the RC delay goals increase the risk of mechanical adhesive and/or cohesive failure of the device during packaging or even in service. Therefore, the mechanical properties of low-k dielectrics must be studied in detail. This is made very challenging by the fact that they have submicron thickness and that they often display a graded structure due to the damage introduced by exposure to different plasmas during processing. In this context, we demonstrate that nanoindentation is very well suited to study this type of materials. We will show how conventional depth sensing nanoindentation is of limited value to characterise the extent of the plasma induced damage because this extents just a few tens of nanometres and the graded structure can not be sampled with enough depth resolution. However, nanoindentation in modulus mapping mode can achieve enough depth resolution to characterise such nanoscale graded structures. In this technique, the electrostatic force acting on the indenter tip is sinusoidally modulated, while contact mode imaging at a very small force is performed. The dynamical response is then analyzed to extract the local indentation modulus of the sample at each pixel. By using this technique, we have depth profiled the mechanical properties of the plasma induced damage region of OSG films exposed to different plasmas, by acquiring modulus maps as a function of thickness removed in wear experiments. The results correlate well with the density depth profiles derived from X-Ray Reflectivity measurements.

Handovers between shifts are known causes of preventable adverse events in hospitals. In order to gain an insight into the information transfer that occurs between shifts of senior staff in an emergency department, we observed handovers, interviewed practitioners and distributed questionnaires. We found that merely considering the transfer of "hard data", such as patients' heart rate, blood pressure, etc. can be insufficient: the transfer of "soft data" such as the ambiguity of intuition is also a central aspect in this type of work environment and vital for successful crosscoverage. We describe design concepts that address capture, visualization and transfer of intuition for the handover process. Addressing the issue of intuition support can be a challenge but also a rewarding opportunity for human-computer interaction research in supporting health care handovers.

Dynamic legged locomotion entails navigating terrain at high speed. The impact shocks from rapid footfalls, pivotal for such mobility, introduce large impulses that saturate motion measurement. A biomimetic approach is presented in which visual information, in the form of optical flow, complements information from inertial sensors. The motion is then determined using a two-phase Hybrid Extended Kalman Filter. Experimentation in determining attitudes on a robotic leg platform shows a reduction in drift over inertial approaches and in delay over visual approaches. In tests with 6g impulses, pose was recovered within 5 deg rms with angular rate errors limited to 10 deglsec at frequencies up to 250 Hz.

Routing protocols are important to exchange routing information between neighboring routers. Such information is used to update routing tables and to share in formation about status of the network so that traffics to appropriate destinations will be fast and efficient. Different types of routing protocols are in widespread use across the Internet. Apart from determining optimal routing paths and canying traffics through the networks, these routing protocols should have additional functionalities to support network policies, traffic engineering and security'. In this paper we discuss the use of one such routing protocol the Border Gateway Protocol (BGP) which is the industry standard. We also present an algorithm in which each Autonomous System (AS) decides how to forward its traffic satisfying end-to-end- QoS for its users and services. Our proposed algorithm is dynamic in that network status and route advertisements, which change with time and based on naffic loads in the network, are monitored and taken as input to the final decision on n affic fomwding between ASs.

A systematic technique is developed to improve the AR bandwidth of circularly polarized stacked microstrip antennas (CPSMAs) to about 14% by optimizing the location of the feed and a few other parameters. A new C-type single feed is explored for this proposes. Then a CPSMA is integrated with a quasi-planar short horn to enhance its gain. Our results indicate that it is possible to increase the gain by 4.5 dB without compromising the 3 dB axial ratio (AR) bandwidth or the 10dB return loss bandwidth of the CPSMA. The final design has a gain of 11.5 dBi, 3dB AR bandwidth of 15.2%, minimum AR of 0.27dB and a 10dB return loss bandwidth of 21.5%. The proposed techniques simplify the design of wideband circularly polarized antennas for medium to high gain applications. © 2006 IEEE.

The most common and highly feared adverse effect of intensive insulin therapy in patients with diabetes is the increased risk of hypoglycemia. Symptoms of hypoglycemia arise from the activation of the autonomous central nervous systems and from reduced cerebral glucose consumption. HypoMon is a non-invasive monitor that measures some physiological parameters continuously to provide detection of hypoglycemic episodes in Type 1 diabetes mellitus patients (T1DM). Based on heart rate, corrected QT interval of the ECG signal and skin impedance, a neural network detection algorithm has been developed to recognize the presence of hypoglycemic episodes. From a clinical study of 21 children with T1DM, associated with hypoglycemic episodes, their heart rates increased (1.16 +/- 0.16 vs. 1.03 +/- 0.11, P<0.0001), their corrected QT intervals increased (1.09 +/- 0.09 vs. 1.02 +/- 0.07, P<0.0001) and their skin impedances reduced significantly (0.66 +/- 0.19 vs. 0.82 +/- 0.21, P<0.0001). The overall data were obtained and grouped into a training set, a validation set and a test set, each with 7 patients randomly selected. Using a feedforward multi-layer neural network with 9 hidden nodes, and an algorithm developed from the training set and the validation set, a sensitivity of 0.9516 and specificity of 0.4142 were achieved for the test set. A more advanced neural network algorithm will be developed to improve the specificity of test sets in the near future.

Head movement is one of the most effective hands-free control modes for powered wheelchairs. It provides the necessary mobility assistance to severely disabled people and can be used to replace the joystick directly. In this paper, we describe the development of Bayesian neural networks for the classification of head movement commands in a hands-free wheelchair control system. Bayesian neural networks allow strong generalisation of head movement classifications during the training phase and do not require a validation data set. Various advanced optimisation training algorithms are explored. Experimental results show that Bayesian neural networks can be developed to classify head movement commands by abled and disabled people accurately with limited training data

Assistive technologies have recently emerged to improve the quality of life of severely disabled people by enhancing their independence in daily activities. Since many of those individuals have limited or non-existing control from the neck downward, alternative hands-free input modalities have become very important for these people to access assistive devices. In hands-free control, head movement has been proved to be a very effective user interface as it can provide a comfortable, reliable and natural way to access the device. Recently, neural networks have been shown to be useful not only for real-time pattern recognition but also for creating user-adaptive models. Since multi-layer perceptron neural networks trained using standard back-propagation may cause poor generalisation, the Bayesian technique has been proposed to improve the generalisation and robustness of these networks. This paper describes the use of Bayesian neural networks in developing a hands-free wheelchair control system. The experimental results show that with the optimised architecture, classification Bayesian neural networks can detect head commands of wheelchair users accurately irrespective to their levels of injuries.

Artificial stock markets (ASMs) are very complex. Agent-based ASMs (ABASMs) have become quite popular in the research of ASMs. However, it is very hard and time consuming to design and implement an ABASM from scratch. This paper proposes a novel design of a framework for ABASMs based on our previous work on agent services-oriented architectural design (ASOAD). This design integrates service-oriented computing (SOC) and agent-based computing (ABC) to achieve a more powerful and flexible framework for ABASMs. The resulting system makes it easy to build actionable ASMs for experiments.

In this report, a new technology of adaptive modulation and coding is proposed. This technique is designed for a cognitive radio system. The proposed technique is implemented into an ultra high speed wireless system. The system has maximum 400 Mbps throughput with 80 MHz bandwidth. It is considered as an expanded model of the standard systems on IEEE 802.11a and 802.11n. When the throughput becomes high such as our designed wireless system, it is not easy to keep its throughput high enough under various circumstances. In order to obtain the optimum throughput under these circumstances, the proposed technique determines adaptively the specification of modulation and coding where several specifications of modulation can be designed and can be adaptively selected in our system. This report presents its evaluation of our proposed techniques. It is shown that the optimum condition is usually obtained in our system. © 2006 IEEE.

View description>>
Numerous studies have shown that the process of packet arrivals from Web traffic exhibits strong long-range dependence, which makes it not amenable to be described using the convenient but necessarily short-range dependent framework of Poisson modeling. However, Web traffic is ultimately driven by independent human behavior, so it seems natural to search for an underlying 'seed process', consistent with Poissonity, indirectly driving the packet arrivals of Web traffic. Our study examines Web traffic at different levels of packet aggregation, using powerful statistical analysis tools for identifying the finest level that can be effectively modeled using a homogeneous Poisson process. We show that the arrivals of HTTP responses, TCP connections and Web pages do not provide a satisfactory seed process. However, we find Poissonity in the arrivals of 'navigation bursts'. A navigation burst is a tightly-spaced sequence of Web pages downloaded by the same Web client, which can be explained by fast navigation through several pages before reaching relevant content. Our analysis suggests that the start times of such navigation bursts, which we identify by detecting user think times between 12 and 30 seconds, can be effectively modeled as a homogeneous Poisson process. We believe that our methodology can be extended to other complex modeling problems where finding Poissonity can greatly simplify parsimonious modeling. © 2006 IEEE.

The fully automated docks in Australia present opportunities for applications of autonomous vehicles and engineering innovation. When planning tasks to be done by multi-autonomous vehicles in an enclosed area with a known dynamic map (i.e. bi-directional path network), there are many issues that have not yet been comprehensively solved. The real world presents more complexity than the initial algorithms addressed. There are problems that occur due to interaction with the real-world. This means autonomous vehicles can stop, are affected, or face problems, and hence tasks and vehicles' paths and motion need to be replanned. In order to replan, a greater understanding of the state of vehicles, the state of the map, and importantly the importance of tasks and vehicles is definitely needed. This paper explores the improvements made to replanning by gaining a thorough understanding of the map and then utilising map information to make the best, most efficient replanning decision. Five replanning methods are investigated and four options which combine the methods in different ways are tested in this research. A map analysis method is also presented. Simulation studies show that map information based replanning is the most efficient method out of those tested

This paper describes CSIRO's research and deployment work in technologies for the management and control of distributed energy devices. This work is designed to provide real-time, two-way communication and decision making between distributed energy (DE) resources- loads and generators- in electricity distribution networks. The general DE management and control concept is based on a decentralised architecture, which is a significant shift from the control architectures normally employed in electrical distribution systems. This architecture has a number of advantages, including scalability, improved economics of installation, inherent reliability by removing central points of failure, and improved granularity of data gathering and control functions. The applications of our decentralised management and control architecture are many, but include improving grid reliability, allowing consumers to play a more active role in their energy usage, and benefiting the network by alleviating the effects of peak wholesale prices and network constraints. The technology is aimed deployment in the Australian National Electricity Market within the next five years, and this paper details our latest work in this area. It includes a discussion of CSIRO's theoretical and simulation research efforts into multi-agent distributed systems, whilst also detailing work trialling the distributed energy management and control system in a real-world context.

For a realistic representation of a terrain Light Detection and Ranging data (LiDAR) requires trillion numbers of points. These points connected in triangles that represent the surface of the terrain ultimately increase the data size. For online GIS interactive programs it has become highly essential to reduce the number of triangles in order to save more storing space. In this paper, it is extended to the LiDAR data compression. A newly developed data compression approach to approximate the LiDAR surface with a series of non-overlapping triangles has been presented. Generally a Triangulated Irregular Networks (TIN) are the most common form of digital surface model that consists of elevation values with x, y coordinates that make up triangles. Compression of TIN is needed for efficient management of large data and good surface visualization. This approach covers following steps: First, by using a Delaunay triangulation, an efficient algorithm is developed to generate TIN, which forms the terrain from an arbitrary set of data. A new interpolation wavelet filter for TIN has been applied in two steps, namely splitting and elevation. In the splitting step, a triangle has been divided into several sub-triangles and the elevation step has been used to 'modify' the point values (point coordinates for geometry) after the splitting. Then, this data set is compressed at the desired locations by using second generation wavelets. The quality of geographical surface representation after using proposed technique is compared with the original LIDAR data. The results show that this method can be used for significant reduction of data set.

This paper presents the use of remote sensing data for landslide hazard analysis around Penang Island area, Malaysia. The study area consider as one of the frequent occurrence landslide zone in Malaysia. Efforts have been made to use a linear logistic regression model for landslide hazard delineation by using remote sensing and GIS data. Landslide locations were identified in the study area from interpretation of aerial photographs, high resolution satellite imageries and from field surveys. Terrain information such as land cover, topographic slope, topographic aspect and topographic curvature has been derived from the satellite imageries; and the existing thematic information has been updated to enable the quantification of landslide causative parameters. The other factors chosen that influence landslide occurrence were: lithology, soil, distance from lineament, and distance from drainage and the vegetation index value from SPOT 5 image. Spatial and temporal multi-layered information have been used for landslide hazard analysis. The qualitative hazard analysis has been carried out using the map overlying techniques using the logistic regression model in GIS environment. Landslide locations were used to verify results of the landslide hazard map and the verification results showed 86.62% accuracy. The verification results showed sufficient agreement between the presumptive hazard map and the existing data on landslide areas.

A longitudinal ethnographic study of work practice in a software development company that uses an Agile development approach found that the developers spend a large part of their working time designing, creating, modifying and interacting with infrastructure to enable and support their software development work. This empirical work-in-progress shows that an understanding of situated technology design may have implications for the future development of HCI methods, tools and approaches

The emergence of agile software development methods provides a contribution to contemporary software engineering practices. Agile methods have several benefits over traditional plan-based methods, in particular their ability to handle projects where requirements are not fixed. In the last few years, a number of agile software development methods have been developed but a detailed evaluation (which is essential) of these methods is not available. This paper presents a detailed comparative analysis of two well known agile methods (XP and Scrum), using the previously published 4- Dimensional Analytical Tool (4-DAT), based on four characterization perspectives: those of scope, agility, agile values and software process. A report generated with the help of 4-DAT will assist organizations in making decisions about the selection or adoption of an agile method.

The study is carried out for block lengths of M = 2, M = 4 and M = 8 and it shows that all the spreading matrices show improvement and a better performance over the conventional OFDM over frequency selective channel as expected. As the size ofM increased the spreading matrices which have better orthogonal qualities show greater improvement.

Adaptive Arrays have been used extensively in wireless communications applications to reduce interference between desired users and interfering signals. Significant research has been directed at the Uniform Linear Array (ULA), however, generally a fixed array length is used. In a mobile environment this has the disadvantage of producing a fixed beamwidth due to the fixed array lengths. The Variable Linear Array (VLA) algorithm is a proposed algorithm that allows the beamwidth to be varied by activating and deactivating elements depending on the interferers present. This approach uses the LMS algorithm for adaptation, in an embedded system this could prove costly. This paper proposes an alternative approach based on partial optimization techniques that remove the LMS from the optimization process. Furthermore studies into the cost of having such a system is presented and compared to the operational cost of the LMS algorithm. © 2006 IEEE.

Energy detection receiver is one of the most interesting solution for non-coherent low data rate and low complexity UWB systems. In order to keep the complexity of the receiver structure low the same approach should be used also for ToA (time of arrival) estimation purposes. In this paper, after showing that a generalized maximum likelihood estimator for ToA is a sliding window energy based estimator, an improved version of it that uses partial channel state information is proposed in order to improve the accuracy of the estimation overcoming the hardware limitation related to the minimum integration time of the integration circuit and to the available number of integrators. © 2006 IEEE.

Many different techniques for time-of-arrival (ToA) estimation have been described for UWB signals however they are typically highly complex. Energy detection based architectures have recently been seen as an interesting, low complexity solution for non-coherent ToA estimation. This paper presents a maximum likelihood (ML) ToA estimation strategy based on an energy detection approach utilizing a relatively long integration window. The technique offers improved estimation accuracy whilst overcoming the practical hardware limitation associated with the need for very short integration times in the receiver. © 2006 IEEE.

The application of a new technique, based on the theory of Markov jump parameter systems (MJPS), to the problem of designing controllers to damp power system oscillations is presented in this paper. This problem is very difficult to address, mainly because these controllers are required to have an output feedback decentralized structure. The technique relies on the statistical knowledge about the system operating conditions to provide less conservative controllers than other modern robust control approaches. The influence of the system interconnections over its modes of oscillation is reduced by means of a proper control design formulation involving integral quadratic constraints. The discrete nature of some typical events in power systems (such as line tripping or load switching) is adequately modeled by the MJPS approach, therefore allowing the controller to withstand such abrupt changes in the operating conditions of the system, as shown in the results.

Embedded lossless audio coding embeds a perceptual audio coding bitstream within a lossless audio coding bitstream. Such an approach provides access to both a lossy and lossless version of the audio signal within the one coding scheme. Previously, a lossless embedded audio coder based on the Advanced Audio Coding (AAC) approach and utilizing both backward Linear Predictive Coding (LPC) and cascade coding was proposed. This paper further investigates the adaptation of cascade coding to lossless audio compression using a novel codebook based approach. The codebook is trained using LPC residual signals obtained from the decorrelation stage of the embedded coder. Results show that the overall lossless compression performance of cascade coding closely follows Rice coding.

Speech and gesture modalities can allow users to interact with complex applications in novel ways. Often users will adapt their multimodal behaviour to cope with increasing levels of domain complexity. These strategies can change how multimodal constructions are planned and executed by users. In the frame of Baddeley's Theory of Working Memory, we present some of the results from an empirical study conducted with users of a multimodal interface, under varying levels of cognitive load. In particular, we examine how multimodal behavioural features are sensitive to cognitive load variations. We report significant decreases in multimodal redundancy (33.6%) and trends of increased multimodal complementarity, as cognitive load increases. Copyright the author(s) and CHISIG.

In this study, the analytical modeling of one-dimensional consolidation by vertical drains with vacuum preloading considering both vertical and horizontal drainage is presented. In this method, the total degree of consolidation based on excess pore water pressure dissipation is related to the time factor (T h), drain configuration and anisotropic soil permeability. The analytical predictions are compared with the observed data from consolidation testing. Three different test series were conducted in a large-scale consolidation apparatus designed and installed at the University of Wollongong. It is shown that the authors' analytical model can accurately predict the laboratory behavior. Finally, the analysis of a selected case history employing the authors' model demonstrates the applicability of this approach for typical field conditions. Copyright ASCE 2006.

A system of prefabricated vertical drains (PVDs) with a surcharge load is an effective method for accelerating soil consolidation by promoting radial flow. This study presents a three-dimensional (3D) finite element model for soft soil improved by a single drain. In the finite element analysis, the actual rectangular PVD cross-section is considered, and the equivalent drain diameter is then back calculated based on the consolidation curves. The numerical predictions are then compared to previous studies. The settlements observed in the laboratory are subsequently compared with the three-dimensional finite element analysis incorporating the modified Cam-Clay model and Hansbo's theory.

Ballasted rail track substructure usually consists of graded layers of granular media of ballast and subballast (capping) placed above a compacted subgrade (formation soil). The optimum design of railway track substructure relies on many factors that affect the performance of the track. In this paper, the response of railway track to various factors affecting track performance is investigated by carrying out a parametric study using the finite element analysis (PLAXIS). A plane strain finite element model of railway track section is developed and used for the parametric study. The feasibility of the developed finite element model is examined by comparing its results with measured field test data. The various track factors investigated include the thickness and stiffness of different track layers, shoulder width, and track modulus. The results demonstrate that the subgrade stiffness seems to be the most significant factor affecting track response, thus, the numerical model and experimental data are used to investigate the capability of different stabilization techniques, such as geosynthetics and grout columns, for improving track subgrade behavior.

This paper deals with a quadratic classifier based scheme for the recognition of off-line handwritten numerals of Kannada, an important Indian script. The features used in the classifier are obtained from the directional chain code information of the contour points of the characters. The bounding box of a character is segmented into blocks and the chain code histogram is computed in each of the blocks. Here we have used 64 dimensional and 100 dimensional features for a comparative study on the recognition accuracy of our proposed system. This chain code features are fed to the quadratic classifier for recognition. We tested our scheme on 2300 data samples and obtained 97.87% and 98.45% recognition accuracy using 64 dimensional and 100 dimensional features respectively, from the proposed scheme using five-fold cross-validation technique. © 2006 IEEE.

In a competitive environment, Service Providers wish to deliver services in a lean and agile manner, despite the rising complexity and heterogeneity within the network. The desire to support personalised customer experiences and differentiated services requires that management systems are increasingly flexible, adaptable and dynamic. Policy-based Management (PBM) systems can be helpful in reducing complexity and enhancing flexibility, but they have not typically been involved in end-to-end management of the services, leading to only the partial management of different network functions.

In this paper, we tackle the packet scheduling problem in IEEE 802.16e Wireless Metropolitan Area Network (WMAN), where the Sleep Mode is applied to save energy of Mobile Stations (MSs). Our objective is to design an energy efficient scheduling policy which works closely with the Sleep Mode mechanism so as to maximize battery lifetime in MSs. To the best of our knowledge no power saving scheduling algorithms based on Sleep Mode defined in IEEE 802.16e have been proposed so far in the literature. We propose a Longest Virtual Burst First (LVBF) scheduling algorithm which schedules packets of MSs in a virtual burst mode where there is one primary MS and multiple secondary MSs sharing the wireless link resource. LVBF prolongs MSs' lifetime by reducing the average time when MSs stay in the idle state and the number of state transitions between the awake and sleep states. Simulation results show that, in comparison with the round robin scheduling scheme, LVBF can produce significant overall energy saving, while guaranteeing the QoS requirements of MSs in terms of their minimum data rates. © 2006 IEEE.

This paper presents a new methodology for allocation of sensors in Multi Station Assembly processes. It resolves two core issues i.e. determining the optimal number of sensors to be used and the best locations for each of sensors. The effect of noise on the sensor placement has been minimized by maximizing the determinant of Fisher information matrix. The paper conceives objective function that is significant over other contributions in respect of adding the effect of noise coupled with the sensor data. To optimize the proposed objective function, a new algorithm is developed that combines Chaotic sequences with traditional Evolutionary Fast Simulated Annealing (EFSA) and therefore termed as chaos embedded fast simulated annealing (CEFSA). The proposed algorithm finds the optimal sensor distribution and allocation with minimum noise term in sensor data. The paper also reports the details of a numerical example, carried out in an industrial context to test the efficacy of proposed algorithm. Further analysis reveals that the proposed approach to obtain optimal number of sensors and selection of best locations offers more generic results compared to previously concluded analysis.

Transmission power control has often been used in wireless packet networks to improve the channel reuse and reduce energy consumption. It has been mainly applied to single-input single-output (SISO) systems, where each node is equipped with a single antenna. In this paper, we propose a power-controlled channel access protocol for MIMO-capable wireless LANs with two antennas per node. Our protocol, called E-BASIC, is based on a modification of the classic CSMA/CA access scheme, where we dynamically adjust the "transmission mode" and the transmission power on a per-packet basis so as to minimize the total energy consumption. By "transmission mode" we mean one of the four possible transmit/receive antenna configurations: 1 × 1 (SISO), 2 × 1 (MISO), 1 × 2 (SIMO), and 2 × 2 (MIMO). Our energy model accounts for both the transmission and the circuit powers. While the MIMO mode requires less RF transmission energy than the other three modes, it also incurs the highest circuit energy consumption. Depending on the transmitter-receiver distance, any of the four modes can be the "optimal" one in terms of minimizing the total energy consumption. We study the performance of E-BASIC in ad hoc and infrastructure-based scenarios and compare it with two channel access protocols (802.11 and BASIC) that use a fixed transmission mode (SISO or MIMO) all the time. Our simulations show that E-BASIC often consumes much less total energy than the reference protocols. We further incorporate E-BASIC into the design of a power-aware routing (PAR) scheme that uses a variant of Dijkstra's algorithm to select the most energy-efficient end-to-end path between nodes.

Recent progress in proteomics, computational biology, and ontology development has presented an opportunity to investigate protein data sources from a unique perspective that is, examining protein data sources through structure and hierarchy of Protein Ontology (PO). Various data mining algorithms and mathematical models provide methods for analyzing protein data sources; however, there are two issues that need to be addressed: (1) the need for standards for defining protein data description and exchange and (2) eliminating errors which arise with the data integration methodologies for complex queries. Protein Ontology is designed to meet these needs by providing a structured protein data specification for Protein Data Representation. Protein Ontology is a standard for representing protein data in a way that helps in defining data integration and data mining models for Protein Structure and Function. We report here our development of PO; a semantic heterogeneity framework based on relationships between PO concepts; and analysis of resultant PO Data of Human Proteins. We also talk in this paper briefly about our ongoing work of designing a trustworthy framework around PO. © 2006 IEEE.

Legged robots display a characteristically periodic motion. Measuring and tracking this motion has traditionally been performed using general inertial measurement techniques. While widely applied in robotics, this approach is limited in dynamic legged locomotion due to the excessive accumulation of drift from severe impact shocks (nearly 9 g in single leg experiments). This paper introduces the attitude estimation problem for legged locomotion and shows preliminary results from a more powerful combined range and inertial sensing approach. Based on a modified Extended Kalman Filter the method uses ground-directed range sensors, the stride period, and other periodic features of legged locomotion in order to address inertial drift. Together this provides rapid, robust estimates of flight phases and attitude necessary for extended dynamic legged operations.

Lately, impulse-radio (IR) based ultra wideband (UWB) has emerged as a leading candidate for short range data communications with positioning capabilities. This paper examines the performance of time of arrival (TOA) position estimation techniques of an IR UWB non-coherent energy collection receiver. We present the performance of two different algorithms, namely, the threshold-crossing (TC) and the maximum selection (MAX) algorithms in terms of time of arrival (TOA) estimation error in IEEE 802.15.3 channel models. The architectures of TOA MAX and TC algorithms, suitable for implementation into IR-UWB based non-coherent receivers are presented and evaluated in a top-down design methodology using a hardware description language. The goal is to evaluate the UWB IR energy collection receiver with TOA capabilities on a complete simulation platform. © 2006 IEEE.

This paper presents an overview of performance of non-coherent, ultra-wideband (UWB) impulse radio (IR) receivers specifically focussing on Auto-correlation (AC) and energy detection (ED) receivers. In this paper, we use the term non-coherent receiver to denote a system where the phase of the received signal is not used in the detection and synchronization. The performance comparison is based on a simplified analysis of the bit error rate (BER) of different receivers for different modulation types; specifically binary pulse position modulation and binary pulse amplitude modulation. Compared with AC receivers, the ED receiver is significantly lower complexity supporting ease of implementation. An example implementation of one ED receiver architecture is presented. The test circuits of the transceiver are designed for 0.35μm SiGe BiCMOS technology. The noise figure of the front-end of the ED receiver is 7.3dB while the receiver gain is 34dB. The power consumption of UWB-IR transceiver circuits is 136mW with 100% duty cycle with a 3.3V power supply. © 2006 IEEE.

This paper aims to establish block-structured nonlinear model (Hammerstein model) to predict oxygen uptake during moderate treadmill exercises. In order to model the steady state relationship between oxygen uptake (oxygen consumption) and walking speed, six healthy male subjects walked on a motor driven treadmill at six different speed (2,3,4,5,6, and 7 km/h). The averaged oxygen uptake of exercisers at steady state was measured by a mixing chamber based gas analyzer (AEI Moxus Metabolic Cart). Based on these reliable experiment data, a nonlinear static function was obtained by using Support Vector Regression. In order to capture the dynamics of oxygen uptake, a suitable Pseudo Random Binary Signal (PRBS) input was designed and implemented on a computer controlled treadmill. Breath by breath analysis of all exercisers' dynamic responses (PRBS responses) to treadmill walking was performed. A useful ARX model is identified to justify the measured oxygen uptake dynamics within the aerobic range. Finally, a Hammerstein is achieved, which is useful for the control system design of oxygen uptake regulation during treadmill exercises

This paper proposes a novel integrated approach for the identification and control of Hammerstein systems to achieve desired heart rate tracking performance for an automated treadmill system. The pseudo-random binary sequence input is employed to decouple the identification of dynamic linear part from static nonlinearity. The powerful e-insensitivity support vector regression is adopted to obtain sparse representations of the inversion of static nonlinearity in order to obtain an approximated linear model of the Hammerstein system. An H infin controller is designed for the approximated linear model to achieve robust tracking performance. This new approach is applied to the design of a computer-controlled treadmill system for the regulation of heart rate during treadmill exercise. Minimizing deviations of heart rate from a preset profile is achieved by controlling the speed of the treadmill. Both conventional proportional-integral-derivative (PID) control and the proposed approaches have been employed for the controller design. The proposed algorithm achieves much better heart rate tracking performance

This paper presents comprehensive results of a series of collapse tests on unsaturated compacted clay using a suction-controllable triaxial apparatus for identifying the collapse behaviour, which includes deformation characteristics such as volume changes and hydraulic characteristics such as degree of saturation changes. The collapse tests were conducted by decreasing the imposed matric suction from 147 to 0kPa step by step under constant isotropic net stresses. Experimental data show that the wetting-induced collapse deformation mainly depends on the initial density and mean net stress at which the collapse occurs, i.e., the denser the specimen or the larger the mean net stress, the smaller the collapse deformation. In addition, the soil-water characteristic curve obtained for an initial denser specimen tends to shift upwards in the Sr - lns plane, compared to an initially looser specimen. It is shown that the collapse mainly occurs in the suction range from 20 to 80 kPa for the tested soil. Copyright ASCE 2006.

This paper presents a series of experimental results obtained from wetting and/or drying cyclic tests and constant suction triaxial tests on unsaturated compacted clay with different initial densities using two suction-controllable triaxial apparatus. The primary objective of this research is to investigate the influence of the soil density on the soil-water-retention behaviour. The initial density and initial degree of saturation were controlled by changing the compaction energy using clay powders with almost the same water content. The test results contain the water-retention curves and deformation behavior at different initial densities using different specimens and one specimen before and after collapse. The test data indicate that the measured water-retention curves vary with the current specimen density. A denser specimen results in a higher degree of saturation at the same imposed suction, which implies that the water-retention curve shifts to the right in the ln s-Sr plane. Copyright ASCE 2006.

Multimodal User Interaction (MMUI) technology aims at building natural and intuitive interfaces allowing a user to interact with computer in a way similar to human-to-human communication, for example, through speech and gestures. As a critical component in MMUI, Multimodal Input Fusion explores ways to effectively interpret the combined semantic interpretation of user inputs through multiple modalities. This paper presents a novel approach to multi-sensory data fusion based on speech and manual deictic gesture inputs. The effectiveness of the technique has been validated through experiments, using a traffic incident management scenario where an operator interacts with a map on a large display at a distance and issues multimodal commands through speech and manual gestures. The description of the proposed approach and preliminary experiment results are presented. Copyright the author(s) and CHISIG.

This paper presents a one step smooth and efficient path planning algorithm for navigating a large robotic platform in known cluttered environments. The proposed strategy, based on the generation of a novel search space, relies on non-uniform density sampling of the free areas to direct the computational resources to troubled and difficult regions, such as narrow passages, leaving the larger open spaces sparsely populated. A smoothing penalty is also associated to the nodes to encourage the generation of gentle paths along the middle of the empty spaces. Collision detection is carried out off-line during the creation of the configuration space to speed up the actual search for the path, which is done on-line. Results prove that the proposed approach considerably reduces the search space in a meaningful and practical manner, improving the computational cost of generating a path optimised for fine and smooth motion

This paper addresses efficiency issues identified in the Bitstream Syntax Description Language used by the MPEG-21 generic multimedia adaptation framework. In particular, when used to adapt modern content formats such as H.264/AVC, the time required for processing increases exponentially relative to the duration of the bitstream. In response, the paper proposes several additional features for the Bitstream Syntax Description Language which reduce the complexity of adaptation using BSDL to a linear function of bitstream duration. These features are implemented and validated using bitstreams of real-world length.

In this paper, we expand the idea of spreading the transmitted symbols in OFDM systems by unitary spreading matrices based on the rotated Hadamard or rotated Discrete Fourier Transform (DFT) matrices proposed in the literature to apply to Space-Time Coded Multiple-Input Multiple-Output OFDM (STC-MIMO-OFDM) systems. We refer the resulting systems to as STC-MIMO Block Spread OFDM (STC-MIMO-BOFDM) systems. In the proposed systems, a multi-dimensional diversity, including time, frequency, space and modulation diversities, can be used, resulting in better bit error performance in frequency selective Rayleigh fading channels compared to the conventional OFDM systems with or without STCs. Simulations carried out with the Alamouti code confirm the advantage of the proposed STC-MIMO-BOFDM systems.

This paper presents an efficient approach for low-level control of an unmanned ground vehicle (UGV) operating in rough terrains. In particular, it tackles with the problem of overshoot in the vehicle braking system that arises from severe nonlinearity and input time-delay. The resultant high-performance and robustness of the control system are achieved by cascading a sliding mode controller (SMC) in series with a conventional PID controller. The idea is based on modelling the system as a second order time-delay system under PID control while the SMC is incorporated to shape the control input for time-delay and nonlinearity compensation. An output predictor is also employed here to obtain the necessary information to realize the proposed controller. The validity of the proposed approach is verified through simulations for the braking system of UGVs developed at our Centre.

Maximum margin discriminant analysis (MMDA) was proposed that uses the margin idea for feature extraction. It often outperforms traditional methods like kernel principal component analysis (KPCA) and kernel Fisher discriminant analysis (KFD). However, as in other kernel methods, its time complexity is cubic in the number of training points m, and is thus computationally inefficient on massive data sets. In this paper, we propose an (1 + ε) 2-approximation algorithm for obtaining the MMDA features by extending the core vector machines. The resultant time complexity is only linear in m, while its space complexity is independent of m. Extensive comparisons with the original MMDA, KPCA, and KFD on a number of large data sets show that the proposed feature extractor can improve classification accuracy, and is also faster than these kernel-based methods by more than an order of magnitude.

A method for spectrum spreading in an Orthogonal Frequency Division Multiplexing (OFDM) system is proposed in this paper, resulting in a Spread Spectrum OFDM (SS-OFDM) system suitable for ultra-wideband (UWB) applications. By modifying the IFFT module in a conventional OFDM transmitter and interleaving the modulated signal samples within an OFDM symbol, the transmitted signal spectrum is spread greatly to realize spread spectrum communications. This method of spectrum spreading is also compared with that of the Multiband OFDM (MB-OFDM) system. The SS-OFDM signal has the characteristics of a white noise, and its power spectrum density is constant within the desired bandwidth. One of the main advantages of the proposed system is that it can be used for UWB communication without the need for frequency hopping. In addition, the transmitted signal bandwidth can be selected flexibly to meet different system requirements. © 2006 IEEE.

Hospitals around the world are taking advantage of wireless LAN-based computing technologies in view of their mobility, flexibility, and speed to improve the quality and reduce the cost of patient care. The handheld computers have evolved into a viable platform for these organizations to access and manage the patients' information wirelessly from any point of care. However, the deployment of the handheld technology is hindered by the lack of automation of workflows in the present hospital system architecture. In this paper, thin client architecture with workflow decision making is presented by considering the outpatient workflow. The prototype is not intended to replace the workflows in the healthcare but to facilitate the health care professionals to receive useful and relevant information on time with greater flexibility than before. The prototype focuses on exchanging information with existing legacy systems, updating data in real time, and making them available to healthcare professionals by organizing daily routines in the ward

By copying information from sources and distributing it to new destinations we do not lose information at the sources. Nevertheless, exchange of information is still restricted by patent law, as well as by institutional, cultural and traditional hurdles that create protective barriers hindering the free flow of this valuable commodity. We believe that one of the greatest challenges we face in creating a new research paradigm will be building the community modeling and information sharing culture. How do we get engineers and scientists to put aside their traditional modes of doing business? How do we provide the incentives that will be required to make these changes happen? How do we get our colleagues to see that the benefits of sharing resources far outweigh the costs? We argue that timely sharing of data and information is not only in the best interest of the research community, but that it is also in the best interest of the scientist who is doing the sharing.

Information integration with the aid of ontology can roughly be divided into two levels: schema level and data level. Most research has been focused on the schema level, i.e., mapping/matching concepts and properties in different ontologies with each other. However, the data level integration is equally important, especially in the decentralized semantic Web environment. Noticing that ontology data (in the form of instances of concepts) from different sources often have different perspectives and may overlap with each other, we develop a matching method that utilizes the features of ontology and employs the machine learning approach to integrate those instances. By exploring ontology features, this method performs better than other general methods, which is revealed in our experiments. Through the process that implements the matching method, ontology data can be integrated together to offer more sophisticated services

Improving the network throughput is a primary objective in mobile ad hoc networks (MANETs), which is motivated by the over-conservative nature of the 802.11 standard. Transmission power control (TPC) was proposed for improving spatial reuse and reducing energy consumption in MANETs. Previous TPC protocols either incur extra hardware cost (e.g., require multiple transceivers) or do not fully exploit the potential of power control. In this work, we propose distributed, single-channel MAC protocols for MANETs that exploit TPC and account for different packet sizes in the system to further maximize spatial reuse. We model channel contention in the network as a non-cooperative game. Multiple potential transmitters are first involved in an admission phase which enables terminals to compute the transmission powers that achieve a Nash equilibrium (NE) for a given utility function. Subsequently, successful contenders in the same neighborhood can simultaneously proceed with their transmissions. Simulation results show that our protocols significantly improve the network throughput (in terms of transmitted bits/second or the number of admitted contenders) over previously proposed schemes. Our results also indicate that these gains do not require additional energy cost. © 2006 IEEE.

View description>>
GPS/INS integrated systems have been used in mapping applications for direct geo-referencing, which needs very accurate position and attitude solutions. However, due to the limited constellation of GPS satellites and their geometric distribution, the accuracy of GPS positioning cannot meet the requirements of large scale aerial photogrammetry. A GPS/INS integrated system with pseudolite (PL) augmentation for large scale airborne surveying is introduced in this paper. Comprehensive analysis is conducted for geometry design of the integrated system for airborne surveying. Only appropriately located PL can strengthen the GPS satellite geometry significantly, and minimize the impacts of PL location errors and the tropospheric delay modelling error at the same time. As PLs are comparatively close to receivers, the unit vectors from a PL to the reference and rover receivers can be significantly different. Tropospheric delay modelling error cannot be effectively mitigated in the differencing procedure. PL signals only propagate through the lower troposphere, where it is very difficult to model the signal delay due to spatial variations of atmospheric parameters and dense water vapour. Several models are introduced and evaluated in this paper for accurately estimating the PL tropospheric delay. Estimation of the PL troposphere modelling errors in a Kalman filter can improve position accuracy further. An extended Kalman filter is applied to process INS raw measurements and GPS/PL carrier phase data for system integration. Carrier phase ambiguities are estimated using the combination of GPS and PL code and phase observations. Double differenced GPS and PL measurements are processed to get initial positioning results. Computed positions based on fixed ambiguities, together with initial Kalman filter parameters are used to initialize the tightly coupled integrated system. Close-loop update in the system corrects INS errors, as the estimated errors are fed back to the inertia...

In this study we aimed to establish the usefulness of the time constant of heart rate recovery (Tr) in the evaluation of cardiovascular fitness. 15 male subjects exercised on recumbent bicycle at three different workloads (75W, 100W 125W) where R-R intervals were monitored to determine Tr. In order to find the maximal oxygen uptake ( 2 max V..O ) of each subject, oxygen consumption rate ( 2 V..O ) was recorded throughout the treadmill exercise (10km/h). Based on 2 max V..O , we classified the subjects into two groups: the fit group and the unfit group. We found a significant difference in Tr between these two groups only existed when the workload was 75W (p .. 0.01) and only at this workload did the R-R intervals achieve stability during the 5 minutes of exercise. Furthermore, we found the cut-off value for predicting cardiovascular fitness at this workload was 55 seconds, with an associated sensitivity of 85.7% and specificity of 87.5%.

For a High Temperature Superconducting (HTS) cable, a non-uniform AC current distribution among the multilayer conductors gives rise to increased AC losses. To get a uniform current distribution among the multilayer conductors, a constrained optimization model is constructed with continuous and discrete variables, such as the winding angle, radius and the winding direction of each layer. Under the constraints of the mechanical properties and critical current of the tape, the Particle Swarm Optimization (PSO) algorithm is employed for structural parameter optimization in both warm and cold dielectric type HTS cables. A uniform current distribution among layers is realized by optimizing the structural parameters. The perturbation analysis is employed to evaluate the parameters after optimization. It is found that the robust stabilizations are different among the various optimal results. The PSO is proved to be a more powerful tool than the Genetic Algorithm (GA) for structural parameter optimization.

A high gain antenna made from dual 1-D electromagnetic bandgap (EBG) resonators is described. The combination of dual resonators with an array feed achieves a wide radiation bandwidth, thereby addressing a major limitation of EBG resonator antennas in general. The proposed antenna uses an array of 32 slots and a stripline corporate feed network to deliver energy to the dual resonator structure. Preliminary theoretical results on radiation patterns and gain of the antenna are discussed. Performance is compared with a classical 1-D EBG resonator antenna containing a single source to highlight the improvement in radiation bandwidth of the proposed configuration. © 2006 IEEE.

This paper investigates the spatial-frequency channel characterization of Ultra-wideband (UWB) wireless communication systems. Firstly, a novel frequency dependent UWB channel model is constructed based on the theory of electromagnetic diffraction mechanism, which causes the field strength to vary with the frequency in each multipath. Secondly, we build a space-frequency model, which includes spatial characteristics such as angular power spectrum, and physical sampling points in space. The space-frequency model has two special cases (i) discrete multipath model, and (ii) cluster model, which can be readily used to generate channel data for any arbitrary set of sensor locations. The reconstruction results from channel measurements show the accurateness of the novel frequency dependent model, with reconstruction error decreasing by 40%, compared to the traditional Turin model. © 2006 IEEE.

This paper proposes a refined Gaussian weighted histogram intersection for content-based image matching and applies the method for number plate categorization. Number plate images are classified into two groups based on their colour similarities with the model image of each group. The similarities of images are measured by the matching rates between their colour histograms. Histogram intersection (HI) is used to calculate the matching rates of histograms. Since the conventional histogram intersection algorithm is strictly based on the matching between bins of identical colours, the final matching rate could easily be affected by colour variation caused by various environment changes. In our recent paper [9], a Gaussian weighted histogram intersection (GWHI) algorithm has been proposed to facilitate the histogram matching via taking into account matching of both identical colours and similar colours. The weight is determined by the distance between two colours. When applied to number plate categorization, the GWHI algorithm demonstrates to be more robust to colour variations and produces a classification with much lower intra-class distance and much higher interclass distance than previous HI algorithms. However, the processing speed of this GWHI method is still not satisfying. In this paper, the GWHI method is further refined, where a colour quantization method is utilized to reduce the number of colours without introducing apparent perceptual colour distortion. New experimental results demonstrate that using the refined GWHI method, image categorization can be done more efficiently.

Root-locus-based PID controller and LQR-based controller always fail as system nonlinearity increases. We here propose the optimization-compensated block/diagram to reinforce the stabilization ability of these two classical control methods for nonlinear system, and besides, to achieve other performance requirements such as constrained overshoot and fast response. The controller design of a nonlinear sliding weights balancing mechanism is based on optimization-compensated root locus and LQR method. First, according to root-locus of the linearized dynamic system, we propose extra poles and zeros addition to roughly draw the locus shifting to left to achieve stabilization requirement. The poles and zeros are realized by P/PD/PID controllers. For LQR approach, we choose performance parameters to meet stabilization and minimum energy requirement. The controller is realized as feedback controller. Further, to compensate the model-error from nonlinearity and to meet other performance such as overshoot and setting time, some P/PID parameters for root-locus method and the feedback gain for LQR method are optimized via optimal parameter searching in NCD/Matlab toolbox. The simulation results demonstrate the stability and the constrained performances of the entire closed-loop system can be ensured by the proposed compensated control block diagrams. © 2006 IEEE.

Image compression has many applications. For example, it is an important step for distributed and network based pattern recognition. For real time object recognition or reconstruction, image compression can greatly reduce the image size, and hence increase the processing speed and enhance performance. Fractal image compression is a relatively recent image compression method. Its basic idea is to represent images as a fixed point of a contractive Iterated Function System (IFS). Spiral Architecture (SA) is a novel image structure on which images are displayed as a collection of hexagonal pixels. The efficiency and accuracy of image processing on SA have been demonstrated in many recently published papers. We have shown the existence of contractive IFS?s through the construction of a Complete Metric Space on SA. The selection of range and domain blocks for fractal image compression is highly related to the uniform image separation specific to SA. In this paper, we will review the current research work on fractal image compression based on SA. We will compare the results obtained on SA and the traditional square structure in terms of compression ratio and PSNR.

Hexagonal structure is different from the traditional square structure for image representation. The geometrical arrangement of pixels on hexagonal structure can be described in terms of a hexagonal grid. Hexagonal structure provides an easy way for image translation and rotation transformations. However, all the existing hardware for capturing image and for displaying image are produced based on square architecture. It has become a serious problem affecting the advanced research based on hexagonal structure. In this paper, we introduce a new virtual hexagonal structure. Based on this virtual structure, a more flexible and powerful image translation and rotation are performed. The virtual hexagonal structure retains image resolution during the process of image transformations, and does not introduce distortion. Furthermore, images can be smoothly and easily transferred between the traditional square structure and the hexagonal structure.

Polyurethane is one of the most biocompatible polymers and has been used widely in vivo. In this paper, the magnetite nanoparticles were synthesized by chemical precipitation under different conditions. The as-prepared samples were characterized by X-ray diffraction and transmission electron microscopy, and their magnetic properties were evaluated on a vibrating sample magnetometer. Then the magnetite nanoparticles with different amounts were doped into polyurethane directly and composite films were made. Reinforced by the inorganic particles, PU composite films were also characterized by Fourier transform infrared spectra and mechanical tests., and the surface morphology of the composite film was observed by Atomic Force Microscope The results showed the composite material was reinforced by magnetic nanoparticles and also showed magnetic behavior. This kind of composite materials have the potential to be used as hyperthermia treatment in biomedical field, like coatings on cardiovascular stents.

In this paper, a digital image technique is used to measure the displacements of sand particles at the soil-steel interface in friction tests. The friction tests are used to study the frictional characteristics between cohesionless soils and mild steel and are carried out using a shear box type apparatus. In order to observe the particle displacements, the front side of the shear box is made of a transparent glass plate and photos can thus be taken continuously by a CCD camera with a magnification of x32 through this observation window. These continuous photos are analyzed by image processing to track the movements and the rotations of soil particles. It is well known that the frictional behavior is influenced by the roughness of the surfaces. Therefore, three kinds of roughness for the steel surface are employed in the tests, i.e. very rough (Rmax ≥ 50 μm), medium (Rmax = 9.3 μm) and very smooth (Rmax = 2.4 μm). The normal stress is kept constant at 100 kPa during the tests. The soil specimen is Toyoura sand with a relative density of D≒r = 90%. The test results show that: (1) The digital image technique is effective in capturing the movements and rotations of soil particles near the steel surface. (2) In the case of a very rough steel surface, the soil particles move very actively, except those adjacent to the frictional boundary. (3) In the case of a very smooth steel surface, the rotation of particle near the interface is limited. (4) The volume change of the soil specimen depends on the rotation of soil particles and very little volume change occurs in the case of a very smooth steel surface. © 2006 Taylor & Francis Group.

The direct torque controlled (DTC) permanent magnet synchronous motor (PMSM) drive has become competitive compared with other types of drive systems because of its simple and sensorless control algorithm. The application of the system, however, is handicapped by the difficulty of starting under full load due to the unknown initial rotor position. This paper presents a nonlinear model of PMSMs which incorporates both the structural and saturation saliencies to enable the numerical simulation of initial rotor position detection algorithms. In this model, the phase inductances are expressed by Fourier series as functions of the stator current and rotor position. The inductances of a surface mounted PMSM is measured with different rotor positions and DC offset currents, which emulate the effect of the three phase stator currents. By using the proposed model, the DTC PMSM is simulated and the results are compared with those obtained by the PMSM model in the Simulink library. With the model, an initial rotor position estimation scheme using voltage pulses is investigated by numerical simulation. The scheme is also experimentally tested and the results are compared with the inductance variation to verify the validity of the method. The effectiveness of the scheme to estimate the initial rotor position for the testing SPMSM is analyzed and verified by numerical simulation before physical implementation

We consider the problem of continuously maintaining order sketches over data streams with a relative rank error guarantee ε. Novel space-efficient and one-scan randomised techniques are developed. Our first randomised algorithm can guarantee such a relative error precision ε with confidence 1 - δ using O(1/ε 2 log 1/δ loge ε 2 N) space, where N is the number of data elements seen so far in a data stream. Then, a new one-scan space compression technique is developed. Combined with the first randomised algorithm, the one-scan space compression technique yields another one-scan randomised algorithm that guarantees the space requirement is O(1/∈ log(1/ε log 1/δ (1/ε log 1/δ) log 2+α εN/1-1/2 α) (for α > 0) on average while the worst case space remains O(1/ε 2 log 1/δ log ε 2 N). These results are immediately applicable to approximately computing quantiles over data streams with a relative error guarantee ε and significantly improve the previous best space bound O( 1/ε 3 log 1/δ log N). Our extensive experiment results demonstrate that both techniques can support an on-line computation against high speed data streams. © 2006 IEEE.

This paper presents boundary polynomial point interpolation meshless method (BPPIM) and boundary radial point interpolation meshless method (BRPIM) based on polynomial basis function (PBF) and radial basis function (RBF) respectively for transient eddy current analysis, and their interpolation shape functions satisfy the Kronecker delta function, thus the essential boundary conditions can be directly imposed on the boundary nodes. An example on analyzing transient eddy current of a square metal column is set to prove the validity of the proposed methods, and a comparison on accuracy between BPPIM and BRPIM is analyzed as well. © 2006 IEEE.

The multiquadric radial basis function method (MQ RBF or, simply, MQ) developed recently is a truly meshless method with global basis functions. It was introduced for solving many 1D and 2D PDEs, including linear and nonlinear problems. However, few works are found for electromagnetic PDEs, say nothing of 3D problems. This paper presents an improved MQ method for 3D electromagnetic problems. Numerical results show a considerable improvement in accuracy over the traditional MQ method, although both methods are direct collocation method with exponential convergence. © 2006 IEEE.

Efficient road traffic incident management in metropolitan areas is crucial for the smooth traffic flow and the mobility and safety of community. Traffic incident management requires fast and accurate collection and retrieval of critical data, such as incident conditions, and contact information for the intervention crew, public safety organisations and other resources. Access to critical data by traffic control operators can be facilitated through various human-computer interfaces. This paper describes the judicious introduction of a multimodal interaction paradigm to the user interfaces for incident handling in a metropolitan transport management centre. Prototypes supporting speech and gestural interaction have been built based on user-centred design methodology and their evaluations have been conducted through user studies. The presented innovative user interfaces provide traffic control operators with intuitive, cognitively efficient ways to record traffic incident conditions, facilitate fast retrieval of contact details, and support time-critical incident handling. © 2006 IEEE.

Locating the sensor nodes in an ad hoc wireless sensor network (WSN) is a very challenging task. In general, the network nodes are not synchronised and the internal delays within the sensor nodes may be unknown. As a result, the positioning problem can not be solved by simply using the triangulation method and certain prior information must be provided. In this paper, we consider a scenario where there are a number of nodes whose positions are known, and it is required to locate the other mobile or static sensor nodes within the radio range of each other by measuring the time of arrival (TOA) in the whole system. Two algorithms are employed, the direct method and the linear least squares (LS) estimator. The performance of the two algorithms is investigated. In particular an analytical formula is derived to estimate the performance of the LS estimator. Simulation results agree well with theoretical predictions. © 2006 IEEE.

Application layer anycast possesses the property of flexibility, however, all the proposed application layer anycast routing algorithms are based on probing so far. One disadvantage of probing algorithms is that there are too many probing packets, which degrade the network performance, wast network bandwidth. In this paper, we propose an online algorithm, balance algorithm, for application layer anycast. Compared with the probing algorithms, the proposed algorithm has no probing cost at all. We model the two kinds of algorithms, and analyse the performance of the two algorithms. The results show that the online balance algorithm is better than the probing algorithms in terms of performance. A simulation is conducting as future work.

This paper presents a control strategy suitable for hydrogen/air proton-exchange membrane fuel cells (PEMFCs), based on the process modeling using fuzzy logic. The control approach is tested using a PEMFC stack consisting of 32 cells with parallel channels. An optimal fuzzy-PI controller is designed to mainly control the hydrogen and air/oxygen mass flows, and auxiliary variables such as the temperature, pressure, humidity of the membrane, and proportion of stoichiometry. The fuzzy logic controller possesses many advantages over the PID controllers, such as a higher performance/cost ratio. It is shown experimentally that the optimal fuzzy-PI controller can improve the voltage and current performance of the system when the load changes.

Increasingly, IT systems and Web systems in particular, fall into the class of applications where the scope of the application to be developed cannot be clearly articulated a priori. This is for a range of reasons, but is at least in part due to the complex inter-dependencies which exist between different aspects of the problem domain. While Whereas the core system requirements might be clear, the domain inter-dependencies lead to ancillary requirements which are only identified as the emerging system and its relationship to the domain are understood. A key mechanism in supporting the development of this understanding is the exploration of application pilots or prototypes, and the subsequent identification of solution or problem domain issues. The resolution of these issues will often play a crucial role in supporting the development of domain understanding and hence project scope. In this paper we explore this phenomenon by analysing issue handling across a range of case studies. We describe a model of the issue resolution process and highlight those issues which are most likely to assist in clarification of project scope.

In Web system development, the non-functional requirements (NFRs) are typically considered only briefly during the requirements elicitation stage and not rigorously articulated by either Web developers or the client. This paper reports on an investigation into this issue involving interviews with Web developers who were engaged in commercial Web development projects. The results from this qualitative research highlight that Web developers commonly do not pay sufficient attention to NFRs. This arises due to uncertainty, lack of time, lack of knowledge in the importance of NFRs and partly because NFRs are not readily available and documented from previous similar projects. Web developers also do not elicit NFR at the same time and at the same level of details as functional requirements (FRs). This study highlights that a lack of rigor in articulating NFRs may significantly impact on the development effectiveness and the quality of the resulting Web system.

Organizational decision making often involves two decision levels. When the leader at the upper level attempts to optimize his/her objective, the follower at the lower level tries to find an optimized strategy according to each of possible decisions made by the leader. Furthermore, such bilevel decision making may involve uncertain parameters which appear either in the objective functions or constraints of the leader or the follower. Following our previous work on fuzzy bilevel decision making, this study proposes a solution concept and related theorems for general- fuzzy-number based fuzzy parameter bilevel programming problems. It then develops an approximation Branch-and-bound algorithm to solve the proposed problem. © 2006 PIPS.

This paper proposes a fast algorithm detecting license plates in various conditions. There are three main contributions in this paper. The first contribution is that we define a new vertical edge map, with which the license plate detection algorithm is extremely fast. The second contribution is that we construct a cascade classifier which is composed of two kinds of classifiers. The classifiers based on statistical features decrease the complexity of the system. They are followed by the classifiers based on Haar-features, which make it possible to detect license plate in various conditions. Our algorithm is robust to the variance of the illumination, view angle, the position, size and color of the license plates when working in complex environment. The third contribution is that we experimentally analyze the relations of the scaling factor with detection rate and processing time. On the basis of the analysis, we select the optimal scaling factor in our algorithm. In the experiments, both high detection rate (with low false positive rate) and high speed are achieved when the algorithm is used to detect license plates in various complex conditions.

This paper proposes an algorithm for real-time license plate detection. In this algorithm, the relatively easy car plate features are adopted including the simple statistical feature and Harr-like feature. The simplicity of the object features used is very helpful to real-time processing. The classifiers based on statistical features decrease the complexity of the system. They are followed by the classifiers based on Haar-like features, which makes the final classifier invariant to the brightness, color, size and position of license plates. The experimental results obtained by the proposed algorithm exhibit the encouraging performance.

Data mining is currently becoming an increasingly hot research field, but a large gap still remains between the research of data mining and its application in real-world business. As one of the largest data users in Australia, Centrelink has huge volume of data in data warehouse and tapes. Based on the available data, Centrelink is seeking to find underlying patterns to be able to intervene earlier to prevent or minimize debt. To discover the debtor patterns of Centrelink customers and bridge the gap between data mining research and application, we have done a project on improving income reporting to discover the patterns of those customers who were or are in debt to Centrelink. Two data models were built respectively for demographic data and activity data, and decision tree and sequence mining were used respectively to discover demographic patterns and activity sequence patterns of debtors. The project produced some potentially interesting results, and paved the way for more data mining applications in Centrelink in near future. © 2006, Australian Computer Society, Inc.

In this paper, a number recognition algorithm is proposed on spiral architecture, a hexagonal image structure. This algorithm employs RULES-3 inductive learning method to recognize numbers. The algorithm starts from a collection of samples of numbers from number plates. Edge maps of the samples are then detected based on spiral architecture. A set of rules are extracted using these samples by RULES-3. The rules describe the frequencies of 9 different edge masks appearing in the samples. Each mask is a cluster of 7 hexagonal pixels. In order to recognize a number plate, all numbers are tested one by one using the extracted rules. The number recognition is achieved by counting the frequencies of the 9 masks. In this paper, a comparison between results based on rectangular structure and the results based on spiral architecture is given. From the experimental results, we can make the conclusion that Spiral Architecture is better than rectangular structure for inductive learning-based number recognition

Bilevel decision addresses the problem in which two levels of decision makers, each tries to optimize their individual objectives under constraints, act and react in an uncooperative, sequential manner. Such a bilevel optimization structure appears naturally in many aspects of planning, management and policy making. However, bilevel decision making may involve many uncertain factors in a real world problem. Therefore it is hard to determine the objective functions and constraints of the leader and the follower when build a bilevel decision model. To deal with this issue, this study explores the use of rule sets to format a bilevel decision problem by establishing a rule sets based model. After develop a method to construct a rule sets based bilevel model of a real-world problem, an example to illustrate the construction process is presented.

In this paper, a new approach named focal region-based volume rendering for visualizing internal structures of volumetric data is presented. This approach presents volumetric information through integrating context information as the structure analysis of the data set with a lens-like focal region rendering to show more detailed information. This feature-based approach contains three main components: (i) A feature extraction model using 3D image processing techniques to explore the structure of objects to provide contextual information; (ii) An efficient ray-bounded volume ray casting rendering to provide the detailed information of the volume of interest in the focal region; (iii) The tools used to manipulate focal regions to make this approach more flexible. The approach provides a powerful framework for producing detailed information from volumetric data. Providing contextual information and focal region renditions at the same time has the advantages of easy to understand and comprehend volume information for the scientist. The interaction techniques provided in this approach make the focal region-based volume rendering more flexible and easy to use.

Energy efficiency is widely regarded as one of the major challenges for wireless sensor networks. In the literature, the issue is normally addressed from the viewpoint of a specific protocol layer or functionality, such as medium access control (MAC) or routing. In this paper, energy conservation in wireless sensor networks is treated with a holistic approach and examined across all protocol layers and functionalities including MAC, topology management, routing and sensor protocols. The advantages and disadvantages of different protocols for different layers are reviewed and discussed. Some recommendations on the employment of protocols for small, medium and large scale wireless sensor networks are presented. © 2006 IEEE.

Outlier detection is a key element for intelligent financial surveillance systems which intend to identify fraud and money laundering by discovering unusual customer behaviour pattern. The detection procedures generally fall into two categories: comparing every transaction against its account history and further more, comparing against a peer group to determine if the behavior is unusual. The later approach shows particular merits in efficiently extracting suspicious transaction and reducing false positive rate. Peer group analysis concept is largely dependent on a cross-datasets outlier detection model. In this paper, we propose a new cross outlier detection model based on distance definition incorporated with the financial transaction data features. An approximation algorithm accompanied with the model is provided to optimize the computation of the deviation from tested data point to the reference dataset. An experiment based on real bank data blended with synthetic outlier cases shows promising results of our model in reducing false positive rate while enhancing the discriminative rate remarkably. © 2006 IEEE.

Traditional financial surveillance system usually discriminates suspicious transaction by comparing every transaction against its corresponding account history. This process always results in high false positive rate because it is regardless of the existence of economic cycle and business fluctuation. We conceived a new analyzing prototype by comparing an account time series transaction data against its peer group. It has deeply considered the influence of normal fluctuation widely existing in real life and could efficiently reduce the number of false positives with a better understanding of customer Sr behavior pattern. A new method Empirical Mode Decomposition (EMD) developed initially for natural and engineering sciences has now been applied to financial time series data. This method has shown its superiorities in analyzing nonlinear and nonstationary stochastic engineering time series over traditional Discrete Fourier Decomposition (DFD) and wavelet decomposition methods. Firstly the complex financial time series is decomposed into some local detail parts and one global tendency part which represent different time scales like daily, monthly, seasonal or annual. Then a linear segment approximation method based on hierarchical piecewise linear representation (LPR) is used to fulfill the quick matching of the major tendency parts between two time series. The results from experiments on real life bank data (foreign exchange transaction data sets) exhibit that the EMD can become a vital technique for the analysis of financial suspicious transaction detection. © 2006 IEEE.

Advances in technology will continue to require smaller circuitry to further reduce the overall size of current communication and sensor systems. One approach to achieve this reduction in size is to develop small, efficient and multi-band transmitting and receiving structures that will fit into restricted areas while simultaneously accommodating the desired frequencies and high data rates. A metamaterial-based antenna paradigm to achieve these often conflicting requirements is proposed. It is demonstrated that specifically designed radiating elements can be spaced much closer than the usual λ/2 distance in an array configuration while maintaining reasonable overall radiation efficiency and directivity.
