We consider the simulation of interacting high-dimensional systems using pairwise interacting qubits. The main tool in this context is the generation of effective many-body interactions, and we examine a number of different protocols for obtaining them. These methods include the usage of higher-order processes commutator method , unitary conjugation or graph state encoding, as well as teleportation-based approaches. We illustrate and compare these methods in detail and analyze the time cost for simulation. In the second part of the paper, we investigate the influence of noise on the simulation process. We concentrate on errors in the interaction Hamiltonians and consider two generic noise models: i timing errors in pairwise interactions and ii noisy pairwise interactions described by Master equations of Lindblad form. We analyze and compare the effect of noise for the different simulation methods and propose a way to significantly reduce the influence of noise by making use of entanglement purification together with a teleportation-based protocol.

Bilevel programming techniques are developed for decentralized decision problems with decision makers located in two levels. Both upper and lower decision makers, termed as leader and follower, try to optimize their own objectives in solution procedure but are affected by those of the other levels. When a bilevel decision model is built with fuzzy coefficients and the leader and/or follower have goals for their objectives, we call it fuzzy goal bilevel (FGBL) decision problem. This paper first proposes a lambda-cut set based FGBL model. A programmable lambda-cut approximate algorithm is then presented in detail. Based on this algorithm, a FGBL software system is developed to reach solutions for FGBL decision problems. Finally, two examples are given to illustrate the application of the proposed algorithm

Agile methods are often seen as providing ways to avoid overheads typically perceived as being imposed by traditional software development environments. However, few organizations are psychologically or technically able to take on an agile approach rapidly and effectively. Here, we describe a number of approaches to assist in such a transition. The Agile Software Solution Framework (ASSF) provides an overall context for the exploration of agile methods, knowledge and governance and contains an Agile Toolkit for quantifying part of the agile process. These link to the business aspects of software development so that the business value and agile process are well aligned. Finally, we describe how these theories are applied in practice with two industry case studies using the Agile Adoption and Improvement Model (AAIM). © 2008 Elsevier Inc. All rights reserved.

Online auctions are one of the most effective ways of negotiation of salable goods over the internet. Software agents are increasingly being used to represent humans in online auctions. These agents can systematically monitor a wide variety of auctions and can make rapid decisions about what bids to place In what auctions. To be successful in open multi-agent environments, 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 prices of goods given the different criteria and 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. © 2008 Universidad de Talca - Chile.

A permanent magnet linear synchronous motor (pMLSM) for a high temperature superconducting (HTS) maglev system has been studied, including the motor structure, control strategy, and analysis techniques. Finite elemeut analysis (FEA) of magnetic field is conducted to accurately calculate major motor parameters. Equivalent electrical circuit is used to predict the drive's steady-state characteristics, and a phase variable model is applied to predict the dynamic performance. Preliminary experiment with a prototype has been made to verify the theoretical analysis and the HTS-PM synchronons driving technology.

Winding inductance is an important parameter in determining the performance of electrical machines, particularly those with large inductance variation. This paper investigates the influence of winding inductance variation on the performance of a three-phase three-stack claw pole permanent magnet motor with soft magnetic composite (SMC) stator by using an improved phase variable model. The winding inductances of the machine are computed by using a modified incremental energy method, based on three-dimensional nonlinear time-stepping magnetic field finite element analyses. The inductance computation and performance simulation are verified by the experimental results of an SMC claw pole motor prototype.

In many situations, for example, in the cores of a rotating electrical machine and the T-joints of multiphase transformers, the magnetic flux varies with time in terms of both magnitude and direction, i.e., the local flux density vector rotates with varying magnitude and varying speed. Therefore, it is important that the magnetic properties of the core materials under various rotational magnetizations be properly investigated, modeled, and applied in the design and analysis of electromagnetic devices with rotational flux. Drawing from the huge amount of papers published by various researchers in the past century, this paper presents an extensive survey on the measurement and modeling of rotational core losses of soft magnetic materials used in electrical machines, particularly from the view of practical engineering application. The paper aims to provide a broad picture of the historical development of measuring techniques, measuring apparatus, and practical models of rotational core losses.

This paper proposes a new technique for visualizing large graphs of several ten thousands of vertices and edges. To achieve a graph abstraction, a hierarchical clustered graph is extracted from a general large graph based on the community structures discovered in the graph. An enclosure geometrical partitioning algorithm is then applied to achieving the space optimization. For graph drawing, it uses a combination of spring-embbeder and circular drawing algorithms that archives the goal of optimization of display space and aesthetical niceness. The paper also discusses an interaction mechanism accompanied with the layout solution. The interaction not only allows users to navigate hierarchically through the entire clustered graph, but also provides a way to navigate multiple clusters concurrently. Animation is also implemented to preserve user mental maps during the interaction.

This paper is concerned with the design of interactive virtual musical instruments. An interaction design strategy which uses on-screen objects that respond to user actions in physically realistic ways is described. This approach allows musicians to `play the virtual instruments using the sound of their familiar acoustic instruments. An investigation of user experience identified three modes of interaction that characterise the musicians' approach to the virtual instruments: instrumental, ornamental and conversational. When using the virtual instruments in instrumental mode, musicians prioritise detailed control; in ornamental mode, they surrender detailed control to the software and allow it to transform their sound; in conversational mode, the musicians allow the virtual instrument to `talk back, helping to shape the musical direction of performance much as a human playing partner might. Finding a balance between controllability and complexity emerged as a key issue in facilitating `conversational interaction.

In this paper, we advocate the usage of the family of Heyting-valued modal logics, introduced by M. Fitting, by presenting a simple 3-valued modal language and axiomatizing an interesting 3-valued logic of belief. We give two simple bisimulation relations for the modal language, one that respects non-falsity and one that respects the truth value. The doxastic logic axiomatized, apart from being interesting in its own right for KR applications, (i) it comes with an underlying 3-valued propositional logic which is a syntactic variant of the 'logic of here-and-there', whose importance in KR and Logic Programming is well-known, (ii) it is endowed from its very inception with a Gentzen-style proof theory from [Fit92] and a completeness theorem from [KNP02], (iii) it can be equivalently seen as a logic describing the epistemic agreement of two interrelated agents: a K45 agent who 'dominates' an S5 agent, (iv) as we show here, its satisfiability problem is NP-complete, i.e. at the lower level one can expect for applied logics. This is the first concrete example of an epistemic logic from Fitting's framework, that has been overlooked hitherto, despite its many attractive characteristics.

Increasingly, people are faced with having to deal with vast amount of digital content. But in some situations, having to choose from such large digital libraries can be unpleasant and even paralysing, especially when people have no strong preference for a particular choice. Digital music listening is an example of such a dilemma. Focusing on Shuffle listening on the iPod, whereby listeners abdicate choice to a system to present content to them randomly, we observe that this mode of abdicating choice not only alleviates the pains of choice but also leads to better user-experience in some circumstances. Randomness is highlighted as a versatile resource. Acting as a device that `defamiliarises the digital music tracks, it refreshes and engages listeners' attention as well as shapes their perceptions. In some cases, the use of randomness enriches their listening experience and even encourages encounters with serendipity.

In this paper, a novel two-stage noise removal algorithm to deal with impulse noise is proposed. In the first stage, an adaptive two-level feedforward neural network (NN) with a backpropagation training algorithm was applied to remove the noise cleanly and keep the uncorrupted information well. In the second stage, the fuzzy decision rules inspired by the human visual system (HVS) are proposed to classify the image pixels into human perception sensitive class and nonsensitive class, and to compensate the blur of the edge and the destruction caused by the median filter. An NN is proposed to enhance the sensitive regions with higher visual quality. According to the experimental results, the proposed method is superior to conventional methods in perceptual image quality as well as the clarity and smoothness in edge regions. © 2008 IEEE.

View description>>
The proposed efficient human detection system is based on an adaptive neural fuzzy network (ANFN). In the preprocessing process, we apply a background subtraction algorithm with Gaussian mixture model (GMM) background model to extract moving objects, and adopt a shadow elimination process to eliminate some noise and irregular moving objects. The modified independent component analysis (mICA) based conditional entropy is presented to extract and select the efficient features (independent components). Furthermore, we use an adaptive neural fuzzy network as a human detection system to recognize human objects. The ANFN model uses a functional link neural network (FLNN) to create the consequent part of the fuzzy rules. The orthogonal polynomial is applied as a functional expansion of the FLNN. The learning process of ANFN consists of structure learning and parameter learning. The structure learning depends on the entropy measure to determine the number of fuzzy rules. The parameter learning, based on the back propagation method, is used to adjust the membership function and corresponding weights of the FLNN. Finally, the proposed human detection system is applied in various circumstances. The results of this study demonstrate the accuracy of the proposed method. © 2008 TFSA.

In order to enhance the immune algorithm (IA) performance and find the optimal solution when dealing with difficult problems, we propose an efficient immune-based particle swarm optimization (IPSO) for neuro-fuzzy classifiers to solve the skin color detection problem. The proposed IPSO combines the immune algorithm (IA) and particle swarm optimization (PSO) to perform parameter learning. The IA uses the clonal selection principle, such that antibodies between others of high similar degree are affected, and these antibodies, after the process, will have higher quality, accelerating the search and increasing the global search capacity. The PSO algorithm has proved to be very effective for solving global optimization. It is not only a recently invented high-performance optimizer that is easy to understand and implement, but it also requires little computational bookkeeping and generally only a few lines of code. Hence, we employed the advantages of PSO to improve the mutation mechanism of the immune algorithm. Simulations have shown the performance and applicability of the proposed method. © 2008 TFSA.

Support vector machines (SVMs) as being good tools for classification problems has been proposed by Vapnik. This paper proposes a supervised feature extraction method based on One-against-All scheme for the multi-class classification problems. In this approach, after embedding all the classes into one feature space and constructing hyperplanes based on One-against-All scheme, we extract the orientation distance features between the examples and every hyperplanes in the space, and then map the new features into another feature space, finally utilize other algorithms to classify them. In order to examine the performance of the proposed approach, One-against-All, One-against-One and the introduced approach are compared using three UCI data sets. From the results, we reported that after mapping the examples two times, the training accuracy and generalization performance is enhanced more or less. Copyright © 2008 Watam Press.

Understanding any given situation requires integrating many pieces of information. Such information has in most cases multiple attributes and is obtained from multiple data sources within multiple time slots. Situation assessors' experience and preference will naturally influence the result of information integration, and hence influence the awareness generated for a situation. This study focuses on how multi-source multi-attribute information about a situation is integrated and how the awareness information for the situation is derived. A learning-based information integration approach, which embeds the fuzzy least squares support vector machine (FLS-SVM) technique, is developed in this study. This approach can assess a situation through integrating and inference obtained information and analyzing related data sources. A series of experiments show that the proposed approach has an accuracy learning ability from assessors' experience in the information integration for generating awareness for a situation.

Organizational decisions and situation assessment are often made in groups, and decision and assessment processes involve various uncertain factors. To increase efficiently group decision-making, this study presents a new rationalpolitical model as a systematic means of supporting group decision-making in an uncertain environment. The model takes advantage of both rational and political models and can handle inconsistent assessment, incomplete information and inaccurate opinions in deriving the best solution for the group decision under a sequential framework. The model particularly identifies three uncertain factors involved in a group decision-making process: decision makers roles, preferences for alternatives, and judgments for assessment-criteria. Based on this model, an intelligent multi-criteria fuzzy group decision-making method is proposed to deal with the three uncertain factors described by linguistic terms. The proposed method uses general fuzzy numbers and aggregates these factors into a group satisfactory decision that is in a most acceptable degree of the group. Inference rules are particularly introduced into the method for checking the consistence of individual preferences. Finally, a real case-study on a business situation assessment is illustrated by the proposed method.

Situation awareness (SA) is an important element to support responses and decision making to crisis problems. Decision making for a complex situation often needs a team to work cooperatively to get consensus awareness for the situation. Team SA is characterized including information sharing, opinion integration and consensus SA generation. In the meantime, various uncertainties are involved in team SA during information collection and awareness generation. Also, the collaboration between team members may be across distances and need web-based technology to facilitate. This paper presents a web-based fuzzy group decision support system (WFGDSS) and demonstrates how this system can provide a means of support for generating team SA in a distributed team work context with the ability of handling uncertain information.

Inconsistency of multi-perspective requirements specifications is a pervasive issue during the requirements process. However, managing inconsistency is not just a pure technical problem. It is always associated with a process of interactions and competitions among corresponding stakeholders. The main contribution of this paper is to present a negotiations approach to handling inconsistencies in multi-perspective software requirements. In particular, the priority of requirements relative to each perspective plays an important role in proceeding negotiation over resolving inconsistencies among different stakeholders. An algorithm of generating negotiation proposals and an approach to evaluating proposals are also presented in this paper, respectively. © 2008 Academy of Mathematics & Systems Science, Beijing, China.

In this paper, a new framework for recommendation of multimedia objects in the environment of the multimedia sharing system has been proposed. It uses two kinds of individual ontologies, one is created for multimedia objects and the second one for system users. The final recommendation process takes into account similarities calculated both between objects' and users' ontologies. These individual ontologies respect all the social and semantic features existing in the system. The entire recommender framework was developed for the use in Flickr, a typical photo sharing system.

Podcasts have been employed extensively in some countries and are now being trialed at a number of universities in Australia. They allow ubiquitous learning whereby students can access a variety of educational material anywhere, anytime on iPods, MP3 players or even desktop computers. There remain many questions about the impact of podcasts on students learning. One issue is how podcasts can be used to support high quality, experiential learning rather than merely perpetuating the old transmission model of education. In this paper, we explore the reasons why students either use, or fail to use, podcasts provided for their education. We report on the motivation of students enrolled in a large first-year information systems subject. These varied considerably and show that podcasts are a useful adjunct for providing for the diverse range of learning styles of our students. However, we also conclude that further research is needed into the use of podcasts to promote deeper learning in our students and how podcasts can act as a support tool for other forms of m-learning.

Objectives: To elucidate the potential relationship between classification of emotional faces and impaired central processing in eating disorders and to investigate the potential mediatory role of alexithymia and depression in this relationship. Methods: Visual-evoked potentials (VEPs) to emotional faces and classification performance were assessed in 12 anorexic females and matched healthy controls. Results: Patients with anorexia nervosa showed no modulation of emotional face processing and displayed significantly increased N200 amplitudes in response to all emotional categories and decreased VEPs in response to unpleasant emotional faces in the P300 time range as compared with healthy controls. They also made more mistakes in emotional face recognition, in particular, for neutral, sad, and disgusted content. Conclusions: There are marked differences in evoked potentials and emotion recognition performances of patients with anorexia nervosa and controls in facial processing. Differences in brain dynamics might contribute to difficulties in the correct recognition of facially expressed emotions, deficits in social functioning, and in turn the maintenance of eating disorders.

Marching-Graph is a new visualization that integrates the graph metaphor and the spatial metaphor into a single visualization. It provides users with highly interactive maps for accessing the logical structures of information that has the geographical attributes. Instead of presenting known facts onto maps, it provides a mechanism for users to visually analyze and seek unknown knowledge through effective human-map interaction and navigation across different spaces. However, the traditional force-directed layout algorithms are very slow in reaching an equilibrium configuration of forces. They usually spend tens of seconds making the layout of a graph converge. Thus, those force-directed layout algorithms can not satisfy the requirement for drawing a sequence of graphs rapidly, while the users are quickly marching through the geographic regions. This paper proposes a fast convergence layout method that speeds up the interaction time while users are progressively exploring a sequence of graphs through a series of force-directed layouts in Marching-Graph. It essentially combines a radial tree drawing method and a force-directed graph drawing method to achieve the fast convergence of energy minimization.

This document reviews the book âRobotics: State of the Art and Future Challengesâ. The review begins by providing a chapter by chapter summary of the book, and then concludes with a detailed review of the entire book. Robotics is a rich and exciting field of Artificial Intelligence. It has taken great strides in the last decade and a book on the state of the art and future challenges is timely. The reviewed book will assist AI researchers to keep abreast of developments in roboticsâa flagship area that enjoys a high profile and profound visibility in broader societyâby providing an empirically based overview of the field. The book a major outcome of a comparative robotics study and unique largely due to the fact that such field studies require a strong team of experts to invest significant time and effort, and site visits require significant funding. The book âRobotics: State of the Art and Future Challengesâ contains an extensive high level comparative review of the field of robotics across several pioneering research centers in several geographical regions by a team of scientists which included experts from NASA and US based universities. The book has seven chapters, and an appendix containing the biographies of team members. The broad field of robotics is divided into the following six research areas each of which has a single chapter devoted to it: robotic vehicles, space robotics, humanoid robots, industrial, service and personal robots, robotics in biology and medicine, and networked robots. The data for the reviews was obtained from site visits to 50 laboratories in countries such as Japan, South Korea, France, Germany, Italy, Spain, Sweden, Switzerland, and the UK. A 51st virtual site visit was conducted to Australia.

The Signal-to-Noise-Ratio (SNR) is often used for identification of biomarkers for two-class problems and no formal and useful generalization of SNR is available for multiclass problems. We propose innovative generalizations of SNR for multiclass cancer discrimination through introduction of two indices, Gene Dominant Index and Gene Dormant Index (GDIs). These two indices lead to the concepts of dominant and dormant genes with biological significance. We use these indices to develop methodologies for discovery of dominant and dormant biomarkers with interesting biological significance. The dominancy and dormancy of the identified biomarkers and their excellent discriminating power are also demonstrated pictorially using the scatterplot of individual gene and 2-D Sammon's projection of the selected set of genes. Using information from the literature we have shown that the GDI based method can identify dominant and dormant genes that play significant roles in cancer biology. These biomarkers are also used to design diagnostic prediction systems.To evaluate the effectiveness of the GDIs, we have used four multiclass cancer data sets (Small Round Blue Cell Tumors, Leukemia, Central Nervous System Tumors, and Lung Cancer). For each data set we demonstrate that the new indices can find biologically meaningful genes that can act as biomarkers. We then use six machine learning tools, Nearest Neighbor Classifier (NNC), Nearest Mean Classifier (NMC), Support Vector Machine (SVM) classifier with linear kernel, and SVM classifier with Gaussian kernel, where both SVMs are used in conjunction with one-vs-all (OVA) and one-vs-one (OVO) strategies. We found GDIs to be very effective in identifying biomarkers with strong class specific signatures. With all six tools and for all data sets we could achieve better or comparable prediction accuracies usually with fewer marker genes than results reported in the literature using the same computational protocols. The dominant genes are ...

Autobiographical memory (AM) is the "memory for the events in one's life" [1]. Often it is assumed that in order to remember all those events, you just need to record everything and when you replay these recordings you will remember those events. You can compare this with a library metaphor that has been used to explain AM according to the record-keeping approach. However, after many years of AM-research it was concluded that AM is stored in a different manner, namely according to the constructionist approach, which often is initiated by memory cues. This paper explains these AM theories, surveys literature on existing augmented memory systems and describes our own work in this area. All this input is combined into eight design recommendations for future augmented memory systems.

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 exploring the domain at an early stage of development will help developers to better understand NFR. A lack of rigour in articulating NFRs may significantly impact on the development effectiveness and the quality of the resulting web system. An evaluation of NFRs may also lead to discovering new FRs.

Bilevel programming deals with hierarchical optimization problems in which the leader at the upper level attempts to optimize his or her objectives, but subject to a set of constraints and the follower's reactions. Typical bilevel programming considers one leader one follower situation and supposes each of them has only one objective. In real world situations, multiple followers may be involved and they may be with different relationships such as sharing decision variables or not, sharing objectives or not. Therefore, the leader's decision will be affected not only by those followers' reactions but also by their relationships. In addition, any of the leader and/or these followers may have multiple conflict objectives that should be optimized simultaneously. Furthermore, the parameters of a bilevel programming model may be described by uncertain values. This paper addresses all these three issues as a whole by particularly focusing on the situation of sharing decision variables among followers. It first proposes a set of fuzzy multi-objective multi-follower bilevel programming (FMMBP) models to describe the complex issue. It then presents an approximation branch-and-bound algorithm to solve the FMMBP problems. Finally, two examples illustrate the proposed models and algorithm.

Bilevel decision techniques have been mainly developed for solving decentralized management problems with decision makers in a hierarchical organization. When multiple followers are involved in a bilevel decision problem, called a bilevel multi-follower (BLMF) decision problem, the leaderâs decision will be affected, not only by the reactions of these followers, but also by the relationships among these followers. The referential-uncooperative situation is one of the popular cases of BLMF decision problems where these multiple followers donât share decision variables with each other but may take othersâ decisions as references to their decisions. This paper presents a model for the referential-uncooperative BLMF decision problem. As the kth-best approach is one of the most successful approaches in dealing with normal bilevel decision problems, this paper then proposes an extended kth-best approach to solve the referential-uncooperative BLMF problem. Finally an example of logistics planning illustrates the application of the proposed extended kth-best approach.

Data mining and knowledge discovery have been applied to datasets in various industries including biomedical data. Modelling, data mining and visualization in biomedical data address the problem of extracting knowledge from large and complex biomedical data. The current challenge of dealing with such data is to develop statistical-based and data mining methods that search and browse the underlying patterns within the data. In this paper, we employ several data reduction methods for visualizing genome-wide Single Nucleotide Polymorphism (SNP) datasets based on state-of-art data reduction techniques. Visualization approach has been selected based on the trustworthiness of the resultant visualizations. To deal with large amounts of genetic variation data, we have chosen to apply different data reduction methods to deal with the problem induced by high dimensionality. Based on the trustworthiness metric we found that neighbour Retrieval Visualizer (NeRV) outperformed other methods. This method optimizes the retrieval quality of Stochastic neighbour Embedding. The quality measure of the visualization (i.e. NeRV) showed excellent results, even though the dataset was reduced from 13917 to 2 dimensions. The visualization results will assist clinicians and biomedical researchers in understanding the systems biology of patients and how to compare different groups of clusters in visualizations.

There is a lack of well-maintained ontologies thus ontology evolution now becomes an important filed of ontology research. The evolution may reflect new categories of systems being evaluated on broader and different understandings of certain concepts and relations. Alternatively ontologies evolve because the conceptualization improves. For ontology evolution, we focus in this paper a social network based approach in which the user community has direct control over the evolution of the ontologies. Ontologies can be enriched, learnt, and obtained from social network users using various empirical techniques. In this paper, we ground the social network based approach on the philosophy of wikis so called ontology Evolution Wiki. © 2008 ACM.

Requirements engineering describes how an IT implementation will support business functions. Most IT systems are operational in nature and typical requirements engineering techniques and methods are usually adequate in capturing and documenting the requirements for such systems. Jackson's problem frames is a technique that is suitable for straightforward IT systems descriptions. However, when an organization deploys an IT system that must deliver upon its competitive business strategy, then an appropriate technique or method needs to be used to capture that business strategy in order to connect it to business-critical IT requirements. Here we provide an overview of the use and adaptation of problem frames to connect requirements to business strategy. We found that a simplification of the problem frames notation was necessary and that to be really effective, we had to integrate problem fames with goal modelling and Map, a method that helps describe the evolution of IT over time.

Abstract: To accommodate an increasing interest in phenomenography among the computing education research community, the authors of this paper have organised two workshops, or intensive courses, in phenomenography, intended for researchers in computing education at a university level. Although the workshop programs contained lectures and smaller exercises, the emphasis was on preparing one joint publication from each of the workshops. The publication from the first workshop discussed the experience of being a teacher in computing, while the second focused on teachersâ experiences of the problems their students encounter when learning computing. The workshops and their impact on the community are discussed in this paper.

Abstract: In this paper we discuss problems related to the teaching of object-oriented programming (OOP). We argue that more research on how the computer science teacher understands OOP would be beneficial. Our argument takes its point of departure in three sets of studies: (1) an ongoing study on how computer science teachers understand core concepts of OOP, (2) a study of how the teaching of OOP is discussed within the CS community, and (3) a set of studies that discuss the different ways in which CS teachers experience their teaching. This paper reports on an ongoing study of the different ways in which computing science teachers understand object- oriented programming, and what they mean when use the term objects first.. The phenomenographic research approach has been applied to the analysis of a discussion that occurred in the SIGCSE-members mailing list. Two understandings of objects first have been identified: (1) as an extension of imperative programming, and (2) as conceptually different from imperative programming. These two understandings are illustrated via the differing ways in which computing science teachers use the term polymorphism.

Under the homoscedastic Gaussian assumption, it has been shown that Fisher's linear discriminant analysis (FLDA) suffers from the class separation problem when the dimensionality of subspace selected by FLDA is strictly less than the class number minus 1, i.e., the projection to a subspace tends to merge close class pairs. A recent result shows that maximizing the geometric mean of Kullback-Leibler (KL) divergences of class pairs can significantly reduce this problem. In this paper, to further reduce the class separation problem, the harmonic mean is applied to replace the geometric mean for subspace selection. The new method is termed maximization of the harmonic mean of all pairs of symmetric KL divergences (MHMD). As MHMD is invariant to rotational transformations, an efficient optimization procedure can be conducted on the Grassmann manifold. Thorough empirical studies demonstrate the effective of harmonic mean in dealing with the class separation problem. © 2008 IEEE.

Indigenous people around the world are becoming more and more interested in ICT. The aural and graphical characteristics of mobile technology and multimedia, in particular, speak to strengths in Indigenous oral and graphical culture. Yet, despite many successful ICT implementations across the globe, there still remain many questions about Indigenous ICT access and adoption. In order to throw light on some of these issues, this paper examines the adoption and use of mobile phones by Indigenous people and how this fits with Indigenous culture. Specifically, we present a preliminary study of mobile phone adoption on a remote island in the Torres Strait with a special focus on Indigenous orality. The study indicates a number of very interesting issues, including an unexpected use of text messaging on mobile phones, as well as phone calls and text messages in the local language Kala Kawa Ya. We tentatively conclude that not only must ICT fit with cultural strengths such as orality but that it must also match key areas of high motivation, such as communication with family.

This paper presents emerging trends in the area of temporal abstraction and data mining, as applied to multi-dimensional data. The clinical context is that of Neonatal Intensive Care, an acute care environment distinguished by multi-dimensional and high-frequency data. Six key trends are identified and classified into the following categories: (1) data; (2) results; (3) integration; and (4) knowledge base. These trends form the basis of next-generation knowledge discovery in data systems, which must address challenges associated with supporting multi-dimensional and real-world clinical data, as well as null hypothesis testing. Architectural drivers for frameworks that support data mining and temporal abstraction include: process-level integration (i.e. workflow order); synthesized knowledge bases for temporal abstraction which combine knowledge derived from both data mining and domain experts; and system-level integration.

In pursuit of photorealistic rendering of surface material, Bidirectional Texture Function (BTF) has been used frequently in recent years. Its main drawback is its massive data size. To solve this, the Spatial Bidirectional Reflectance Function (SBRDF) techniques compress BTFs into reflectance model parameters. However, SBRDF cannot produce the self-shadowing and self-occlusion mesostructure effects in many real-world surfaces. Aiming at this drawback, we investigate how self-shadowing and self-occlusion affect the surface appearance by additional physically-based analysis. We mainly rely on two physical phenomena to separate self-shadowing and self-occlusion into two independent effects. First, the self-shadowing is view independent. Second, the self-occlusion is independent of changes in lighting direction. After those analyses, we are able to add self-shadowing and self-occlusion effects to SBRDF to achieve rendering quality that is much closer to the original uncompressed BTF data than SBRDF.

BRACElet is a multi-institutional multi-national research study of how novice programmers comprehend and write computer programs. This paper reviews the first action research cycle of the BRACElet project and, in the process, charts a path for the upcoming second cycle. The project remains close to educational practice, with much of the data being either data collected directly from exams sat by novices, or data from think-out-Ioud protocols where the task undertaken by a novice or an expert is modelled on an exam question. The first action research cycle analysed data in terms 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. Furthennore, those students who manifested a relational response tended to do better overall in the exam than students who manifested a multistructural response. The second action research cycle will explore the relationship between the ability to read code and the ability to write code. Apart from reporting on the BRACElet project itself, this paper serves as an invitation for institutions and individuals to join the second action research cycle of the BRACElet project.

Abstract: Past papers of the BRACElet project have described an approach to teaching and assessing students where the students are presented with short pieces of code, and are instructed to explain, in plain English, what the code does. The student responses to these types of questions can be analysed according to the SOLO taxonomy. Some students display an understanding of the code as a single, functional whole, while other students cannot âsee the forest for the treesâ. However, classifying student responses into the taxonomy is not always straightforward. This paper analyses the reliability of the SOLO taxonomy as a means of categorising student responses. The paper derives an augmented set of SOLO categories for application to the programming domain, and proposes a set of guidelines for researchers to use.

Numerous studies have shown that a software projectpsilas cost, schedule and defect density escalate as the rate of requirements change increases. Yet none of these studies have explored the effects of not making requirements changes in response to changes in user needs. This paper explains why a project incurs just as much, if not more, risk when requirements changes are suppressed.

Demands on communications networks to support bundled, interdependent communications services (data, voice, video) are increasing in complexity. Smart network management techniques are required to meet this demand. Such management techniques are envisioned to be based on two main technologies: (i) embedded intelligence; and (ii) up-to-the-millisecond delivery of performance information. This paper explores the idea of delivery of intelligent network management as a synthesis of distributed intelligence and information, obtained through information mining of network performance.

Crawlers are software which can traverse the internet and retrieve webpages by hyperlinks. In the face of the inundant spam websites, traditional web crawlers cannot function well to solve this problem. Semantic focused crawlers utilize semantic web technologies to analyze the semantics of hyperlinks and web documents. This paper briefly reviews the recent studies on one category of semantic focused crawlers - ontology-based focused crawlers, which are a series of crawlers that utilize ontologies to link the fetched web documents with the ontological concepts (topics). The purpose of this is to organize and categorize web documents, or filtering irrelevant webpages with regards to the topics. A brief comparison are made among these crawlers, from six perspectives - domain, working environment, special functions, technologies utilized, evaluation metrics and evaluation results. The conclusion with respect to this comparison is made in the final section. © 2008 IEEE.

Ontology is a technology for conceptualizing specific domain knowledge, which can provide machine-readable definitions to the severed domain. Therefore, ontology can be utilized to enhance the performance of focused crawlers, by precisely defining the crawling boundary. In this paper, we will exhibit a conceptual framework of an ontology-based focused crawler serving in the domain of transport services. Here, a transport service ontology is designed for filtering non-relevant metadata, by means of logically linking the metadata with ontological concepts. In addition, we will provide the evaluation process in order to assess the power of ontology in the focused crawler. Conclusion and further works based on our current evaluation results will be made in the final section. © 2008 IEEE.

The research with regards to digital ecosystems emerged in the end of last century, and has developed in this century. Due to its immaturity, some fields within it are deemed to be blank. This research proposes to fill one of the blanks in the digital ecosystems research. By analyzing the issues in the current research, we propose to develop a semantic search engine, with the purpose of querying services provided by SMEs. The objective of this research is to build a reliable and trustworthy link between SMEs in the digital ecosystems environment. Relevant research methods and steps are discussed in this paper.

It is observed that there are few service evaluation and ranking methodologies currently available in the SOE. In this paper, we propose an innovative service evaluation and ranking strategy, based on the measurement of trustworthiness and reputation of services (or service providers'). CCCI Metrics originally proposed and developed by Chang et al [1] is used to measure the trustworthiness and reputation of e-services. Here we extend the application of CCCI Metrics to the field of service retrieval. A java-based search engine prototype is designed, with the purpose of implementing the trustworthiness and reputation-based service search, evaluation and ranking.

Negotiation is defined as two or more agents making agreement on the common interests, which provides an efficient approach for companies to gain business intelligence from suppliers and customers. Current negotiation research focuses on automatically stimulating negotiation behaviors among agents. Ontology, as a modeling technology in semantic web, is regarded as an effective tool to improve the negotiation ability of agents, considering that ontology can provide richer semantic expressions for agents in negotiation process. In this paper, we make a brief review on the current negotiation ontology researches. In addition, by means of a unique ontology notation system, we unify the notations used in these ontologies, to maximally promote knowledge sharing outcome in this field. By comparing and contrasting the ontologies from five perspectives, we draw a brief conclusion to the present status of negotiation ontology researches, and make our suggestions to the further research in this field. © 2008 IEEE.

Centralised government information services such as 'single' or 'universal' number telephone services have been identified as a major component of many government reform agendas. Particularly in the context of recent trends in e-Government and the policy drive toward innovation and transformation of government structures and operations. However, to date there has been little research directed at investigating and understanding the diverse and changing policy motives driving the development of such services. The aim of this study is to offer a more complete understanding of the problems and opportunities that have driven and continue to drive diverse jurisdictions to adopt these types of centralised telephone services for government access, information provision, communication, and transactions. We present a review and analysis of the development of centralised and universal telephone services by a wide range of government jurisdictions with a view to establishing a preliminary policy context. The findings are synthesised to present a more holistic picture of policy motivations and to provide a framework for considering the development of such services. The study findings indicate that the development of 'single' or 'universal' number services is the outcome of a mix of policy drivers which reflect: re-active problem solving; opportunistic evolution as a result of previous action(s), and innovation in technology and its application in service delivery. Further, the problems and opportunities identified have changed over time. These findings are considered in the context of key ideas about policy formation and theoretical, political and ideological issues represented by the oppositions, reactive or pro-active, centralising or decentralising, adaptive or entrepreneurial and, more recently, the perceived challenge by the network to its opposite, hierarchy. In this context imperatives for future research directions are proposed.

Fieldwork has long been identified as providing students undertaking professional studies with a means of implementing theory into a real world context. In recent years some educators, particularly in the health sciences, have introduced mobile devices to support students' fieldwork learning. In many ways there is a natural link between fieldwork and mobile technology. In this paper we report on a trial to introduce mobile support into the study of information systems in the field. The experience showed that mobile devices can assist students collect data in richer, multimedia formats and make subsequent classroom presentations of their field study much more interesting. However, it also revealed certain usage and deployment issues with the mobile devices themselves which have implications for device selection and educational design.

An increasing amount of physiological monitoring data is displayed on medical devices around the world every day. By and large, much of this data is lost beyond hand written annotations. Opportunities exist to utilize this data for improved care of those patients within the NICU and for clinical research. The service oriented architecture paradigm offers a way of thinking of critical care through the provision of services of critical care provided by clinicians where patients may be located within or outside their intensive care unit. A major inhibitor to this becoming reality is the lack of a standard for the representation of physiological data as HL7, for example, does not include definitions for time series data. This research proposes a method to represent, transmit and archive physiological data using DICOM and HL7. To enable this, a DICOM file writer and viewer for the physiological time-series data is proposed to specifically enable the storage requirement for these data. This research is then tested within the context of Neonatal Intensive Care.

Bilevel decision techniques are developed for decentralized planning problems with decision makers located in a two-level system. This study develops a particle swarm optimization based algorithm to solve fuzzy linear bilevel (FLBL) decision problems. A main advantage of this algorithm is that the optimization technique is adopted directly on FLBL problems by fully considering the original information carried by the fuzzy parameters, thus minimizing information loss. Experiments reveal that this algorithm can effectively solve the fuzzy linear bilevel decision problems.

Well-being is a broad subject, which is described in this paper as: a personal balance of mental, social and physical being, influenced by life circumstances and life factors. These factors include emotions, engagement, life satisfaction, intentional activities and social network. The project described in this paper aims at improving well-being through the design of a persuasive and interactive installation for the home environment. After the investigation of well-being by means of a literature study, cultural probes and questionnaires, a concept was developed. This paper describes the design, implementation and evaluation of this concept. 'BLB', as it is called, encourages its users to seize the moment in order to increase their well-being.

To be successful in multi-attribute auction, agents must be capable of adapting to continuous changing bidding price. This paper presents a novel fuzzy attitude based bidding strategy (FA-Bid), which employs dual assessment technique i.e. assessment of multiple attributes of the goods as well as assessment of agents attitude (eagerness) to procure an item in automated auction. The assessment of attributes adapts the fuzzy sets technique to handle uncertainty of the bidding process as well use heuristic rules to determine attitude of bidding agents in simulated auctions to procure goods. The overall assessment is used to determine a price range based on current bid, which finally selects the best one as the new bid.

In the rotor winding magnetomotive force (MMF) of an ac machine, there exist so-called slot harmonics which appear in pairs and the lower order harmonic of each pair rotates in the opposite direction against the fundamental component. In addition, the slot harmonics have the same winding factor as the fundamental component. Based on these properties, this paper develops a brushless doubly fed machine (BDFM) with wound rotor. The machine consists of two stator windings with p1 and p2 pole-pairs, respectively. The rotor has a normal symmetrical multi-phase winding, in which rotating MMFs with p1 and p2 pole-pairs are induced by their stator counterparts. When the number of rotor slots equals the sum p1 and p2, the two MMFs rotate in opposite directions with respect to the rotor, satisfying the requirement of a BDFM. The major advantage of such a machine is that for both p1 and p2 pole-pair MMFs the winding factor is as high as that of the fundamental component, leading to high utilization of rotor winding and electrical efficiency.

The improved model can take into account the effect of magnetic saturation and rotor position dependence of key parameters including back electromagnetic force, winding inductance, cogging torque and core loss, which are obtained from time-stepping nonlinear magnetic field finite element analysis (FEA). The presented model has been implemented in Simulink environment and employed to simulate the dynamic and steady-state performance of the three-phase three-stack PM claw pole motor with soft magnetic composite stator. Parameter computation and performance simulation are validated by experiments on the motor prototype.

In a rotating electrical machine or the T-joints of a multiphase transformer, the magnetic flux is basically three dimensional (3-D) and rotational. This paper presents the 3-D vector magnetic properties of soft magnetic composite (SMC) materials for advanced field analysis of electromagnetic devices with SMC core, which is particularly developed for application of electrical machines with complex structure and 3-D flux. The 3-D magnetic reluctivity tensor is derived from the magnetic measurements on a cubic SMC sample by using a 3-D magnetic property tester. The tensor consists of both diagonal and offdiagonal terms and the latter account for the effect of rotating flux. Practical techniques for employing the vector magnetic properties in field analysis are reviewed and discussed.

Abstract- Today's e-Businesses rely heavily on trust and reputation systems. These systems are key indicators for businesses performance. Businesses that interact with each other for their business needs form a Digital Business Ecosystem (DBE). Members ofDBE need to know the trust and reputation value of each other before the start of business interactions. The feedback mechanism is needed so that members of DBE form a unanimous opinion about trustworthiness of any specific member of the community and based their business interactions on this opinion. We present an ontological framework that will combine the feedback from all different trust and reputation information publicly available for a specific member of a domain and gives the knowledge representation on the bases of combined feedback. We call this ontological framework 'feedback ontology'.

Recent reviews of research in the field of e-government identify a number of limitations of current research practice and call for a reassessment of the research agenda. The overall quality of research outcomes has also been questioned leading to calls for greater openness about the research methods being used and the ways in which findings have been derived. Much e-government research is conducted in partnership with policy-makers and practitioners. In these situations even greater attention to e-government research designs is required. Such designs connect theory and practice, serving the policy needs of practitioners and contributing to advancing scholarship in the field of e-government. In an e-government context this requires us to generate relevant information that informs and shapes e-government policy and at the same time contributes to extending theorisations about the phenomenon of e-government. This raises questions about the ways we conduct research and the ways we engage with practitioners to advance understanding and support the production of actionable knowledge. In this paper we argue that to make theoretical progress and to develop a history of ideas in the e-government field of inquiry requires researchers to be more reflexive about their own practice. This requires us as researchers to share experiences of collaborative interactions between researcher, policy makers and representatives of practice, reflect on the tensions, contradictions and constraints in the process of collaborative sense-making and ask questions about our experiences. Such reflections of research practice are largely unreported. Drawing on material from our collaborative research experiences with a national government agency responsible for e-government policy formulation we discuss the issues and challenges associated with conducting collaborative interactive research and present the wider implications for e-government research practice.

The design and interaction of physical game artefacts is becoming increasingly important for the design of digital tabletop games. In this paper a study is described investigating the differences in interpretations of realistic and abstract game artifacts comparing children and adults. A game was created on a digital tabletop as a carrier for the user evaluation presented in this paper. The appearance of the game artifacts was explored and a family of each of the artifacts was created. The interpretations of each of the individual artifacts and their different visual appearances were tested to determine whether children rank and interpret the functionalities of the artefacts differently than adults. The results showed that overall the understanding of abstract artifacts compared to realistic ones was best for both children and adults. It also indicated there was no significant difference in the interpretations of the realistic and abstract artefacts between children and adults.

According to Amdahl's law, if the power consumption of cache memories is reduced, the embedded processor can significantly save much power. However, the cache misses result in the penalty of thousands of cycles waiting and power consumption due to increasing the number of external memory access. Based on the above reason, the phased cache design is proposed and can largely improve the power consumption which wastes a set-associative cache. In this paper, the embedded pipelining processor without stalling and low-power phase cache is practiced with high-level simulation to achieve high-performance and low-power design. As experimental results, the proposed phase cache can reduce 44% power consumption compared with traditional one-access-cycle cache and eliminate pipeline stalls incurred by phased cache with only 6% gate count overhead. ©2008 IEEE.

Blind source separation of independent sources from their mixtures is a common problem for multi-sensor applications in real world, for example, speech or biomedical signal processing. This paper presents an independent component analysis (ICA) method with information maximiz ation (Infomax) update applied into 4-channel one-line EEG signal separation. This can be implemented on FPGA with a fixed-point number representation, and then the separated signals are transmitted via Bluetooth. As experimental results, the proposed design is faster 56 times than soft performance, and the correlation coefficients at least 80% with the absolute value are compared with off-line processing results. Finally, live demonstration is shown in the DE2 FPGA board, and the design is consisted of 16,605 logic elements. © 2008 IEEE.

In this paper, we present the FC direct trust value-based decision making methodology, for making direct trust value based decisions regarding interactions in (a) a given context and during the current time slot, and (b) a given context and at a future time slot. The direct trust value-based decision making methodology models the context specific nature of trust and the dynamic nature of trust to make direct trust value-based decisions regarding interactions. Additionally in this paper, we present the FC reputation-based trust decision making methodology, for making reputation-based trust decisions regarding interactions, if direct trust value-based decisions cannot be made. The FC reputationbased trust decision making methodology can make reputationbased trust decisions regarding interactions in (a) a given context and during the current time slot, and (b) a given context and at a future time slot.

Before initiating a financial e-commerce interaction over the World Wide Web, the initiating agent would like to analyze the possible Risk in interacting with an agent, to ascertain the level to which it will not achieve its desired outcomes in the interaction. By analyzing the possible risk, the initiating agent can make an informed decision of its future course of action with that agent. To determine the possible risk in an interaction, the initiating agent has to determine the probability of failure and the possible consequences of failure to its resources involved in the interaction. In this chapter as a step towards risk analysis, we propose a methodology by which the initiating agent can determine beforehand the probability of failure in interacting with an agent, to achieve its desired outcomes. © 2009 Springer Berlin Heidelberg.

In an e-commerce business interaction, the risk assessing agent by analyzing the possible level of perceived risk beforehand can make an informed decision of its future course of interaction with an agent. The perceived risk in the context of an e-commerce business interaction is a multidimensional construct which is the combination of its subcategories. In this paper we propose a methodology by which the risk assessing agent can ascertain the numeric and linguistic level of perceived risk in an interaction by combining its different subcategories. © 2008 IEEE.

Rich computer simulations or quantitative models can enable an agent to realistically predict real-world behaviour with precision and performance that is difficult to emulate in logical formalisms. Unfortunately, such simulations lack the deductive flexibility of techniques such as formal logics and so do not find natural application in the deductive machinery of commonsense or general purpose reasing systems. This dilemma can, however, be resolved via a hybrid architecture that combines tableaux-based reasoning with a framework for generic simulation based on the concept of 'molecular' models. This combination exploits the complementary strengths of logic and simulation, allowing an agent to build and reason with automatically constructed simulations in a problem-sensitive manner.

In this panel, we propose to figure out how requirements engineering and interaction design can be usefully combined. In particular, some people argue that scenarios / use cases should be concrete, as in story-telling. Others argue for use of "essential" use cases as a methodological approach to interaction and user-interface design. Somewhat in the middle, it is argued that use cases should help acquiring the requirements in the first place. What should the practitioner believe and, in particular, do, in order to develop useful and usable software and systems? Software development and interaction design require different skills and different methods and are typically done by different people. Still, scenario-based design is proposed for several activities relevant for both tasks, such as requirements elicitation, software design, and interaction design. Symbolic modeling in this spirit is actually common to various fields. However, scenario-based approaches vary, especially with regard to their use, e.g., employing abstract use cases or integrating scenarios with functions and goals in a systematic design process. So, the key issue to be raised at the panel is how to combine different approaches, e.g., in scenario-based development, so that the interaction design as well as the development of the user interface and of the software internally result in an overall useful and useable system. © 2008 IEEE.

People, who interact, cooperate or share common activities within the photo sharing system can be seen as a multirelational social network. The results of their activities, i.e. tags, comments, references to favourites and others that semantically connect users through multimedia objects, i.e. pictures are the crucial component of the semantic web concept. Every online sharing system provides data that can be used for extraction of different kinds of relations grouped in layers in the multirelational social network. Layers and their profiles were identified and studied on two, spanned in time, snapshots of Flickr population for better understanding of social network structure complexity. Additionally, for each of the identified layers, a separate strength measure was proposed in the paper. The experiments on the Flickr photo sharing system revealed that users are inspired by both the semantic relationships between objects they operate on and social links they have to other users. Moreover, the density and affluence of the social network grows over course of time.

In this paper we describe our investigations on the role of material hardness in the haptic experience of tangible artefacts. Without seeing the artifacts children had to rank their experience on a scale of two antonyms while touching and holding these artifacts. In this experiment it was shown that children have no problem ranking hardness. Two groups could be identified: soft artifacts were found to be cute, speedy and warm, e.g., and hard artifacts boring, sad and old-fashioned. We think that paying attention to this factor in the design of tangible user interfaces for children can improve their experience.

Many studies have demonstrated that multiple classifier systems, such as random subspace method, obtain more outstanding and robust results than a single classifier. In this study, we propose a novel RSM framework which is composed of two parts. The first part is the construction of a weighted RSM, where weights are given by two classifier-based distributions. One is the feature weighting distribution, and the other is the subspace dimensionality distribution that helps for dynamically selecting the size of subspace with respect to the employed classifiers. The second part is to introduce the spatial information estimated by the Markov random filed theory into the Bayesian classifiers used in the framework. The real data experimental results show that the proposed framework obtains satisfactory performances, and the classification maps remarkably produce fewer speckles. © 2008 IEEE.

In this paper we reason about the coverage of openly accessible functions using an abstract model of NGN functionality. Defining and using an abstract model allows us to evaluate the effectiveness of open standards from a perspective where a wide range of NGN functionality can be generalised and conveniently categorised. Subsequently, it will be possible to identify the gaps, which are a subset of functionality that we are specifically interested in for our project. © 2008 Springer Berlin Heidelberg.

Abstract This paper examines the capacity of networks of phase coupled oscillators to coordinate activity in a parallel, distributed fashion. To benchmark these networks of oscillators, we present empirical results from a study of the capacity of such networks to colour graphs. We generalise the update equation of Aihara et al. (2006) to an equation that can be applied to graphs requiring multiple colours. We find that our simple multi-phase model can colour some types of graphs, especially complete graphs and complete k-partite graphs with equal or a near equal number of vertices in each partition. A surprising empirical result is that the effectiveness of the approach appears to be more dependent upon the topology of the graph than the size of the graph.

We present an observational study that was conducted to guide the design of an enhanced collaboration platform to support distributed multidisciplinary team meetings between two hospitals. Our goal was to find out how the breast cancer multidisciplinary team collaborates in their face-to-face meetings and in their discussions using an existing videoconferencing system and to identify obstacles and issues to their primary tasks. We identified a set of concerns around the way visibility and audibility affect the social cohesion of the group and impede communication and situation awareness between the distributed team. We also identified a parallel set of concerns around the difficulty of preparing and interacting around the medical images used in the meetings. These issues exposed a complex matrix of technical, social, procedural and organisational factors that affect the collaboration. We suggest potential directions for technical interventions in this setting.

This investigation proposes the novel radix-42and radix-43algorithms with the low computational complexities of the radix-16 and radix-64 algorithms and the low hardware requirements of the radix-4 algorithm. Based on the multiplierless radix-4 butterfly structure, the proposed radix-42single-path delay feedback (R42SDF) design and radix-43single-path delay feedback (R43SDF) design support the 4096-point FFT/IFFT computations. Moreover, the retrenched constant multiplier and eight-folded complex multiplier structures are adopted to decrease the multiplier cost and the coefficient ROM size with the complex conjugate symmetry rule and subexpression elimination technology. To further decrease the chip cost, a finite word-length analysis is provided to indicate that the proposed R42SDF and R43SDF architectures only require 14 and 13-bit internal word-length to achieve 40dB SNR performance in the 4096-point FFT/IFFT computation. The comprehensive comparison results indicate that the proposed R43SDF design has the smallest hardware cost and the highest hardware utilization among the tested architectures for the FFT/IFFT computation, and thus has the highest efficiency. The implementation results show that the proposed R42SDF and R43SDF based 4096-point pipeline FFT/IFFT processors only consumes 6.3725 and 5.985 mW@20 MHz at 1.2V supply voltage in TSMC 0.13 μm CMOS process.

Abstract: In just thirty years, we have gone from punched cards to Second Life. But, as the American National Science Foundation (NSF) recently noted, âundergraduate computing education today often looks much as it did several decades agoâ (NSF, 2006). Consequently, todayâs âNintendo Generationâ have voted with their feet. We bore them. The contrast between the changes wrought via computer research over the last 30 years, and the failure of computing education to adapt to those changes, is because computing academics lead a double life. In our research lives we see ourselves as part of a community that reaches beyond our own university. We read literature, we attend conferences, we publish, and the cycle repeats, with community members building upon each otherâs work. But in our teaching lives we rarely discuss teaching beyond our own university, we are not guided by any teaching literature; instead we simply follow our instincts. Academics in computing, or in any other discipline, can approach their teaching as research into how novices become experts. Several recent multi-institutional research collaborations have studied the development of novice programmers. This paper describes some of the results from those collaborations. The separation of our teaching and research lives diminishes not just our teaching but also our research. The modern practice of stripping away all âdistractionsâ to maximize research output is like the practice of stripping away rainforest to grow beef â both practices appear to work, for a little while, but not indefinitely. Twenty-first century academia needs to bring teaching and research together, to form a scholarship of computing that is an integrated, sustainable, ecological whole.

Abstract: This paper compares the CORE rankings of computing education conferences and journals to the frequency of citation of those journals and conferences in the ACE2005, 2006 and 2007 proceedings. The assumption underlying this study is that citation rates are a measure of esteem, and so there should be a positive relationship between citation rates and rankings. The CORE conference rankings appear to broadly reflect the ACE citations, but there are some inconsistencies between citation rates and the journal rankings. The paper also identifies the most commonly cited books in these ACE proceedings. Finally, in the spirit of âQuis custodiet ipsos custodes?â the paper discusses some ways in which the CORE rankings process itself might in future be made more transparent and open to scholarly discourse.

Abstract: This paper identifies the most commonly cited conferences, journals and books among the 1398 citations made in the 122 publications of the SIGCSE 2007 proceedings. The SIGCSE 2007 authors cited a very large array of conferences, journals and books, but the majority are only cited within a single paper. There are only a very small set of journals and conferences cited frequently. Most books cited are concerned with technical information or are textbooks. Only 2% of books are concerned with computer science education and 23% with education in general. The picture that emerges from this citation analysis is that the SIGCSE community does not have a substantial core set of educational literature. Also, the epistemology of the SIGCSE community is primarily objectivist, with a focus on content, rather than a constructivist, student-centered focus on learning.

This paper reports on a study that explored ways of inventing and devising movement for use in the design of movementbased interaction with video-based, motion-sensing technologies. Methods that dancers, trained in movement improvisation and performance-making, used to choreograph movement were examined as sources of potential methods for technology designers. The findings enabled us to develop methods and tools for creating and structuring new movements, based on felt experience and the creative potential of the moving body. These methods and tools contribute to the ongoing development of a design methodology underpinned by the principle of making strange. By making strange, we mean ways of unsettling habitual perceptions and conceptions of the moving body to arrive at fresh appreciations and perspectives for design that are anchored in the sensing, feeling and moving body.

ABSTRACT: This study analyzed student responses to an examination, after the students had completed one semester of instruction in programming. The performance of students on code tracing tasks correlated with their performance on code writing tasks. A correlation was also found between performance on "explain in plain English" tasks and code writing. A stepwise regression, with performance on code writing as the dependent variable, was used to construct a path diagram. The diagram suggests the possibility of a hierarchy of programming related tasks. Knowledge of programming constructs forms the bottom of the hierarchy, with "explain in English", Parson's puzzles, and the tracing of iterative code forming one or more intermediate levels in the hierarchy.

Product prototype evaluation is an important phase in new product development (NPD). Such evaluation often requires multiple criteria that are within a hierarchy and a group of evaluators. The evaluation process and these evaluation criteria often involve uncertain and fuzzy data in the weights of these criteria and the judgments of these evaluators. To evaluate nonwoven cosmetic product prototypes, this study first develops a NPD evaluation model, which has evaluation criteria within three levels, based on the features of nonwoven products. It then proposes a fuzzy (multi-level) multi-criteria group decision-making (FMCGDM) method for supporting the evaluation task. A fuzzy multi-criteria group decision support system (FMCGDSS) is developed to implement the proposed method and applied in nonwoven cosmetic product development evaluation.

Garment new product development (NPD) evaluation requires considering multiple criteria under a hierarchical structure. The evaluation process often involves uncertainty and fuzziness in both the relationships between criteria and the judgments of evaluators. This study first presents a garment NPD evaluation model under a well-being concept. It then proposes a fuzzy multi-criteria group decision-making (FMCGDM) method to evaluate garment NPD. The advantages of the FMCGDM method include handling criteria in a hierarchical structure, dealing with three kinds of uncertainties simultaneously, and using suitable types of fuzzy numbers to describe linguistic terms. A fuzzy multi-criteria group decision support system (FMCGDSS) is developed to implement the proposed method. Finally a garment NPD evaluation case study demonstrates the proposed method and software system.

We study the parameterized complexity of the following problem: is it possible to make a given graph r-regular by applying at most k elementary editing operations; the operations are vertex deletion, edge deletion, and edge addition. We also consider more general annotated variants of this problem, where vertices and edges are assigned an integer cost and each vertex v has assigned its own desired degree δ(v)∈ ∈{0,...,r}. We show that both problems are fixed-parameter tractable when parameterized by (k,r), but W[1]-hard when parameterized by k alone. These results extend our earlier results on problems that are defined similarly but where edge addition is not available. We also show that if edge addition and/or deletion are the only available operations, then the problems are solvable in polynomial time. This completes the classification for all combinations of the three considered editing operations. © Springer-Verlag Berlin Heidelberg 2008.

We study variants and generalizations of the problem of finding an r-regular subgraph (where r ≥ 3) in a given graph by deleting at most k vertices. Moser and Thilikos (2006) have shown that the problem is fixed-parameter tractable (FPT) if parameterized by (k, r). They asked whether the problem remains fixed-parameter tractable if parameterized by k alone. We answer this question negatively: we show that if parameterized by k alone the problem is W[1]-hard and therefore very unlikely fixed-parameter tractable. We also give W[1]-hardness results for variants of the problem where the parameter is the number of vertex and edge deletions allowed, and for a new generalized form of the problem where the obtained subgraph is not necessarily regular but its vertices have certain prescribed degrees. Following this we demonstrate fixed-parameter tractability for the considered problems if the parameter includes the regularity r or an upper bound on the prescribed degrees in the generalized form of the problem. These FPT results are obtained via kernelization, so also provide a practical approach to the problems presented. © 2008, Australian Computer Society, Inc.

Design space exploration, the generation of alternate designs to identify working designs with varying system properties, has the potential to provide a basis for the optimisation of computer-based system architectures. To utilise design space exploration for this purpose requires that an effective mechanism exist for the storage and application of potential design changes. Heuristics have shown some promise in this area due to their ability to capture expert design knowledge and their flexibility across multiple domains. Heuristics are also especially attractive as change descriptions as they can capture changes that operate across a large spectrum of change detail, from the very detailed to the very abstract. Heuristics are, however, at their most powerful, and their most useful, when they are specified in an abstract manner. This presents a challenge in the formal application of heuristics in capturing design knowledge. Formally describing heuristics inclines their specification of change to be in a more detailed, more concrete, state than an abstract one. This occurs because architectural models tend be both domain specific and are often described at a more concrete level than the level at which the heuristic is described. This has the potential to greatly reduce the effectiveness of heuristics. In this paper we propose that by providing an abstract match method heuristics may be specified in an abstract manner and still be applied to a detailed formal model, thereby eliminating this problem. © 2008 IEEE.

Healthcare providers and governments are under pressure to maintain and improve the quality of care to an increasing volume of critical care patients at either end of the life cycle, namely premature and ill-term babies together with the elderly. The provision of a service of critical care utilizing real-time service-oriented architectures has the potential to enable clinicians to be supported in the care of a greater number patients that are, perhaps more importantly, located elsewhere to their intensive care units. This paper presents a review of recent research in the application of computing and IT to support the service of critical care and determines the trends and challenges for the application of real-time service-oriented architectures within the domain. © 2008 IEEE.

nconsistency is a pervasive issue in software engineering. Both general rules of inconsistency management and special case-based approaches to handling inconsistency have recently been considered. In this paper, we present a process model for handling requirements inconsistency within the viewpoints framework. In this process model, when an inconsistency among viewpoints is detected, a set of candidate proposals for handling inconsistency will be generated using techniques from multi-agent automated negotiations. The proposals are then prioritized using an integrated measurement of inconsistencies. The viewpoints involved in the inconsistency will then enter the negotiations by being presented with the candidate proposals and thus selecting an acceptable proposal based on the priorities associated with each candidate proposal. To facilitate usability, in our process, we assume that the natural language requirements statements are first translated into corresponding logical formulas using a translator software. Moreover, the candidate proposals for handling inconsistency are also translated back from formal logic into natural language before being presented for selection.

View description>>
Brake squeal has become an increasing concern for the automotive industry because of associated warranty costs and the requirement for the continued reduction of interior vehicle noise. Low and high frequency noises in car brakes, often referred to as brake squeal, are known to be a result of nonlinearity, unstable behaviour and bifurcations leading to limit cycle behaviour. By using the data from a separate experimental study designed to determine the influence of the geometric parameters of brake pads (such as the number and location of slots) on brake squeal noise, we examine two new approaches for providing improved understanding of the brake squeal phenomenon: statistical and nonlinear dynamics analyses. Results of the statistical analysis indicate that the performances of certain pad designs correlate with their levels of nonlinearity. The nonlinear time series analysis reveals that, in the experimental data, not only are limit cycle behaviours present but also a route to chaotic solutions can be observed.

India is a multi-lingual, multi-script country. Considerably less work has been done towards handwritten character recognition of Indian languages than for other languages. In this paper we propose a quadratic classifier based scheme for the recognition of off-line handwritten characters of three popular south Indian scripts: Kannada, Telugu, and Tamil. The features used here are mainly obtained from the directional information. For feature computation, the bounding box of a character is segmented into blocks, and the directional features are computed in each block. These blocks are then down-sampled by a Gaussian filter, and the features obtained from the down-sampled blocks are fed to a modified quadratic classifier for recognition. Here, we used two sets of features. We used 64-dimensional features for high speed recognition and 400-dimensional features for high accuracy recognition. A five-fold cross validation technique was used for result computation, and we obtained 90.34%, 90.90%, and 96.73% accuracy rates from Kannada, Telugu, and Tamil characters, respectively, from 400 dimensional features. © 2008 Springer-Verlag Berlin Heidelberg.

In this work, the task of complex computer-based system design optimization involves exploration of a number of possible candidate designs matching the optimisation criteria. However, the process by which the possible candidate designs are generated and rated is fundamental to an optimal outcome. It is dependent upon the set of system characteristics deemed relevant by the designer given the systems requirements. We propose a method which is aimed at providing the designer with guidance based upon description of the possible causal relationships between various system characteristics and qualities. This guidance information is obtained by employing principles of multiparadigm simulation to generate a set of data which is then processed by an algorithm to generate a Bayesian Belief Network representation of causalities present in the source system. Furthermore, we address the issues and tools associated with application of the proposed method by presenting a detailed simulation and network generation effort undertaken as part of a significant industrial case study.

In the Crypto'07 paper [5], Desmedt et al. studied the problem of achieving secure n-party computation over non-Abelian groups. The function to be computed is f G (x 1,...,x n ) :?=?x 1 ·...·x n where each participant P i holds an input x i from the non-commutative group G. The settings of their study are the passive adversary model, information-theoretic security and black-box group operations over G. They presented three results. The first one is that honest majority is needed to ensure security when computing f G . Second, when the number of adversary t=?n2?-1, they reduced building such a secure protocol to a graph coloring problem and they showed that there exists a deterministic secure protocol computing f G using exponential communication complexity. Finally, Desmedt et al. turned to analyze random coloring of a graph to show the existence of a probabilistic protocol with polynomial complexity when t?

This paper examines model-making, specifically prototyping, as a problem-based, and possibly experiential, learning activity. Prototyping activities are increasingly being introduced by schools of architecture around the world for the teaching of architectural design and construction technology. Such activities mediate between sophisticated digital modeling technologies, new materials and new construction techniques, and are a means of enabling students to oscillate between the abstract and the concrete: between the virtual world of the computer screen and the physical reality of a model built to scale from representative materials. This paper reviews the literature on what is being done and how. It discusses whether current prototyping activities are taking advantage of the large body of knowledge contained within theories of experiential learning and proposes that a series of guidelines should be formulated to inform the implementation of experimental prototyping activities in the architecture studio. The paper concludes with my own prototyping case study conducted at the University of Technology, Sydney in 2007, which was deliberately designed as an experiential learning activity. Perceptions of its successes and challenges are discussed. A hands-on construction activity will be provided to engage participants in this session.

Accurate computer network traffic models are required for many network tasks such as network traffic analysis and performance optimization. Existing statistical traffic modelling techniques rely on precise mathematical analysis of extensive measured data such as packet arrival time, packet size and server-side or client-side round trip time. With the advent of high speed broadband networks, gathering an acceptable quantity of data needed for the precise representation of traffic is a difficult, time consuming, expensive and in some cases almost an impossible task. In this work we developed a fuzzy logic based traffic models using imprecise data sets that can be obtained realistically. The model include a parameter, the R parameter, which is also useful for analysis of network traffic.

The paradigm of "access, anytime, anywhere" has been critiqued within the mobile HCI literature as a broad assumption that simplifies understandings of actual work practice, and as an example of rhetoric that allows researchers to ignore the temporal aspects of mobility. The key aspect of technology use that remains unclear, however, when discussing this paradigm is the complexity of the concept "anytime, anywhere" from the perspective of the user. This paper addresses this gap by discussing findings from an empirical study of freelance workers, across both work and social contexts, in which availability emerged as an important concern for participants. This paper explores the ways in which freelancers use their mobile devices to manage their availability to others. Finally, we also consider implications for the ways in which mobility is conceptualised within the mobile HCI literature.

We are happy to present the proceedings of the second international conference on tangible and embedded interaction (TEI'08). The feedback we received in response to the first conference and the call of TEI'08 highlighted that there is a great interest in the state-of-the-art on Tangible Interaction, the research community and even beyond these topics. In its second year the tangible an embedded interaction conference is held in Bonn, Germany. The conference is in cooperation with ACM SIGCHI, with its proceedings to be archived in ACM's Digital Library. With technological advances, computing has progressively moved beyond the desktop into new physical and social contexts. As physical artifacts gain new computational behaviors, they become reprogrammable, customizable, repurposable, and interoperable in rich ecologies and diverse contexts. They also become more complex, and require intense design effort in order to be functional, usable, and enjoyable. Designing such systems requires interdisciplinary thinking. Their creation must not only encompass software, electronics, and mechanics, but also the system's physical form and behavior, its social and physical milieu, and beyond. These proceedings include original research work addressing HCI issues, design, use context, tools and technologies, as well as interactive art works in the domain of tangible and embedded interaction. The contributions range from concrete innovative solutions to inspiring novel ideas. The conference brings together this new field, providing a meeting ground for the diverse communities of research and practice involved with tangibles --- from computing, hardware, and sensor technology, to HCI, interaction design, and CSCW, to product- and industrial design and interactive arts. The conference provides with talks, interactive exhibitions, and posters appropriate presentation forms for different types of contributions.

Graphs are widely used to model complicated data semantics in many applications. In this paper, we aim to develop efficient techniques to retrieve graphs, containing a given query graph, from a large set of graphs. Considering the problem of testing subgraph isomorphism is generally NP-hard, most of the existing techniques are based on the framework of filtering-and-verification to reduce the precise computation costs; consequently various novel feature-based indexes have been developed. While the existing techniques work well for small query graphs, the verification phase becomes a bottleneck when the query graph size increases. Motivated by this, in the paper we firstly propose a novel and efficient algorithm for testing subgraph isomorphism, QuickSI. Secondly, we develop a new feature-based index technique to accommodate QuickSI in the filtering phase. Our extensive experiments on real and synthetic data demonstrate the efficiency and scalability of the proposed techniques, which significantly improve the existing techniques

ABSTRACT: This paper explores the programming knowledge of novices using Biggs' SOLO taxonomy. It builds on previous work of Lister et al. (2006) and addresses some of the criticisms of that work. The research was conducted by studying the exam scripts for 120 introductory programming students, in which three specific questions were analyzed using the SOLO taxonomy. The study reports the following four findings: when the instruction to students used by Lister et al. - "In plain English, explain what the following segment of Java code does" - is replaced with a less ambiguous instruction, many students still provide multistructural responses; students are relatively consistent in the SOLO level of their answers; student responses on SOLO reading tasks correlate positively with performance on writing tasks; postgraduates students manifest a higher level of thinking than undergraduates.

ABSTRACT: We have applied Simon's system for classifying computing education publications to all three years of papers from ICER. We describe the process of assessing the inter-rater reliability of the system and fine-tuning it along the way. Our analysis of the ICER papers confirms that ICER is a research-intensive conference. It also indicates that the research is quite narrowly focused, with the majority of the papers set in the context of programming courses. In addition we find that ICER has a high proportion of papers involving more than one institution, and high proportions of papers on the themes of ability/aptitude and theories and models of teaching and learning.

Abstract: The 157 computing education papers from the past eight NACCQ conferences are categorised and summarised by a group of researchers from multiple institutions, with steps taken to measure and improve the consistency of classification. The papers are set predominantly in programming subjects, hardware/architecture/systems/ network subjects, and capstone projects. The bulk of the papers are about teaching/learning techniques, assessment techniques, teaching/learning tools, curriculum, and educational technology. Most of the papers are set within single subjects, a few in multiple subjects within a single program or department, and fewer still in a range of subjects across the whole institution or multiple institutions. Nearly a quarter of the papers either expound a position or outline a proposal; a large but diminishing proportion report on something such as a change of curriculum or approach; and a large and increasing proportion are clearly research papers, focusing on the analysis of data to answer an explicit research question.

Finding and removing misclassified instances are important steps in data mining and machine learning that affect the performance of the data mining algorithm in general. In this paper, we propose a C-Support Vector Classification Filter (C-SVCF) to identify and remove the misclassified instances (outliers) in breast cancer survivability samples collected from Srinagarind hospital in Thai- land, to improve the accuracy of the prediction models. Only instances that are correctly classified by the filter are passed to the learning algorithm. Perform- ance of the proposed technique is measured with accuracy and area under the re- ceiver operating characteristic curve (AUC), as well as compared with several popular ensemble filter approaches including AdaBoost, Bagging and ensemble of SVM with AdaBoost and Bagging filters. Our empirical results indicate that C-SVCF is an effective method for identifying misclassified outliers. This ap- proach significantly benefits ongoing research of developing accurate and robust prediction models for breast cancer survivability.

Traditions encircle the grieving process. These can support mourners in difficult times, for example by prescribing how to behave appropriately and by expressing a sense of history. On the other hand, this traditional approach can prevent the innovation of this field, thereby missing out on potential support when in sorrow over a lost one. This is what we tried to explore with the work described in this paper. We supported the grieving process by creating two design solutions for mourners. Both concepts focus on communicating commemoration between mourners: the Tilting Picture concept for people that are colocated, and the Mourning Stones concept for people that are not colocated.

Nowadays, supply chain information is increasingly used by many entities around the world. Then, the need of sharing information from different sources is an obvious consequence from such proliferation of systems. Unfortunately, integrating supply chain information is not a trivial issue, because data and knowledge exchange among users of supply chain information systems presents many challenges. We must deal with the heterogeneity problem, which increase complexity of integration approaches. This paper discusses issues related to the use of ontologies in the development of supply chain information systems and proposes the creation of software components from diverse ontologies as a way to share data and supply chain information.

Safety stock, a very important composing of the stock management, which is significant for reducing the cost and increasing interests for an enterprise, is the base of the setting of enterprise's stocks, so it is crucial for stock management to presume a rational and exact SS. In this paper, introducing fractal theory, a new method based on the fractal collage theorem and the iterative process of fractal interpolation functions was proposed to forecast the safety stock. Based on the fractal collage theorem, it uses the iterated function system whose attractor is close to the historical data to establish the fractional function, and set the forecasting model proposed according to the iterative process of fractional function. Then by an example the rationality and reliability of this method is verified, and the result show that it is helpful indeed to set the reasonable safety stock for enterprise.

In this paper, we study a signal processing problem which concentrates on outlier detection and data mining in order to rediscover some useful information. Moreover, the great difficulty of the subject is caused by both the external environment and the internal mechanism. In the external, owing to limit of impersonal condition, such as, realistic disturbance from noise signal can not avoid. In the internal, the masking effect appears in outlying observation so as to produce some unreasonable results by data analysis. Therefore, based not only on the requirement of external quality assurance schemes, but also on internal quality control where screening for outliers should probably be part of the procedure for our main goal. As a consequence, we have applied data accumulated generating operation and sample median test for solving the conundrum.

It is significant to evaluate the situations of oil security for taking national oil security measures, because very important relationships exist between the oil security and the national security. A novel combined method is presented in this paper, which is based on using principal component analysis (PCA) and fuzzy cluster analysis (FCA) modeling. It is used for assessing oil security. In this paper, the data of 13 years is taken as sample and 10 indexes are selected to constitute an evaluation system for oil security. PCA is used for reducing the dimensions of indexes, and the new indexes are formed for oil security. Then FCA is used for classifying the 13 samples. At last a dialed analysis is made and some suggestions are put forward to ensure oil security.

The aim of this paper is to predict the inventory of the relevant upstream enterprises in supply chain. The support vector machine, a novel artificial intelligence-based method developed from statistical learning theory, is adopted herein to establish a short-term stage forecasting model. However, take the fact into account that demand signal is affected by variant random factors and behaves big uncertainty, the predicted accuracy of SVM is not approving when the data show great randomness. It is obligatory that we present Markov chain to improve the predicted accuracy of SVM. This combined model takes advantage of the high predictable power of SVM model and at the same time take advantage of the prediction power of Markov chain modeling on the discrete states based on the SVM modeling residual sequence. Then we use the statistical data of the output of the gasoline of China from Feb-06 to Dec-07 for a validation of the effectiveness of the above model.

Prediction is important for the electricity capacity management. Accurate prediction can help the policymaker make correct decision and promote the decision making quality. For improving an accuracy of prediction, in this paper, we adopt the theory of Grey prediction to develop a new forecasting approach that integrates historical data of the gross domestic products (GDP) into an electric capacity forecasting. We adopted Grey prediction as a forecasting means because of its fast calculation with as few as four data inputs needed. As a result, our study considered that Wu and Chen proposed a modeling method of the improved grey relational analysis and main shows that the general Grey model, GM (1, 1), which is an especial case, is adequate to handle an electrical power system. In this study, the prediction is improved significantly by applying the transformed Grey model and the concept of average system slope. The adaptive value of a in the Grey differential equation is obtained quickly with the average system slope technique. In such a way, the wastage of electric consumption can be avoided. That is, it is another achievement of virtual electric power plant. ©2008 IEEE.

The grounding problem remains one of the most fundamental issues in the field of Artificial Intelligence. We argue that representations are grounded information and that an intelligent system should be able to make and manage its own representations.

Grounding robot representations is an important problem in Artificial Intelligence. In this paper we show how a new grounding framework guided the development of an improved locomotion engine [3] for the AIBO. The improvements stemmed from higher quality representations that were grounded better than those in the previous system [1]. Since the AIBO is more grounded under the new locomotion engine it makes better decisions and achieves its design goals more efficiently. Furthermore, a well grounded robot offers significant software engineering benefits since its behaviours can be developed, debugged and tested more effectively. © 2008 Springer-Verlag Berlin Heidelberg.

In this paper we explore the development of systems for software engineering ontology instantiations management in the methodology for multi-site distributed software development. Ultimately the systems facilitate collaboration of teams in multi-site distributed software development. In multi-site distributed environment, team members in the software engineering projects have naturally an interaction with each other and share lots of project data/agreement amongst themselves. Since they are not always residing at the same place and face-to-face meetings hardly happen, there is a need for methodology and tools that facilitate effective communication for efficient collaboration. Whist multi-site distributed teams collaborate, there are a lot of shared project data updated or created. In a large volume of project data, systematic management is of importance. Software engineering knowledge is represented in the software engineering ontology whose instantiations, which are undergoing evolution, need a good management system. Software engineering ontology instantiations signify project information which is shared and has evolved to reflect project development, changes in the software requirements or in the design process, to incorporate additional functionality to systems or to allow incremental improvement, etc. © 2009 Springer Berlin Heidelberg.

In this paper, we focus on the returns generated by assets that are not reported. These refer mainly to the assets other than those reported on the balance sheet. These sources create value to organisations. Traditional capital e.g. physical and human capitals cannot guarantee future success of a business. We define and include social capital as an internal-based source and market capital as an external-based source for sustainable business performance. These intangible assets may represent a huge source but at the same time they are the hardest to quantify and express numerically and tangibly. There is a lack of a standard metric method to measure this kind of knowledge and assests. Ontology, a particular type of knowledge based technology, can be used to help understand how knowledge within organisations creates value. By making knowledge explicit and transparent, it promotes trust which in turn promotes governance. Generally speaking, an ontology is used to explicitly express how the intellectual capital is valued and thus results are sensible for managers. The ontology enables evidence based formation of knowledge valuation. © 2008 IEEE.

An early warning system (EWS) is critical to saving lives and mitigating loss from disasters. Literature addresses specific technical issues of EWSs in different hazard domains, however, only a few discussions on framework and standards. The paper proposes a set of practical designing standards and a comprehensive EWS integration framework. The framework takes considerations of human factors, lead-time and feed-back issues, therefore more suitable for a wide range of applications in practice.

For micro robotic applications, piezoelectric actuators are widely used, whereas electromagnetic actuators are not favored because of the complex structures and difficult fabrication. On the other hand, electromagnetic actuators have many merits that are suitable for robotic applications, such as relatively large displacement or stroke and no need of high voltage power supply. With the recent fast development of micro precision machining techniques, the fabrication of complex structures is no longer a problem. This paper presents our recent study of developing electromagnetic actuators for micro robotic applications, including a comparison between piezoelectric and electromagnetic actuators, design of two types of electromagnetic actuators, and fabrication and testing of a moving magnet tubular linear actuator.
