Indigenous people around the world are becoming more interested in information technology because they see it as a way to preserve their traditional cultures for future generations as well as a way to provide their communities with economic and social renewal. However, the cost of the new technologies, geographic isolation, and a lack of computer literacy have made it difficult for indigenous people to adopt IT. Information Technology and Indigenous People provides theoretical and empirical information related to the planning and execution of IT projects aimed at serving indigenous people. It explores many cultural concerns with IT implementation, including language issues and questions of cultural appropriateness, and brings together cutting-edge research from both indigenous and non-indigenous scholars. © 2007 by Idea Group Inc.

This paper discusses ongoing research at Deakin University, which focuses on developing wikis to foster web-based learning communities. Research to date has used wikis to facilitate collaborative icebreaker exercises, discussions, and to create knowledge repositories. Student feedback has contributed to the iterative revision of the wiki interface, the icebreaker exercise and the development of new tasks for students to complete using the wiki. The analysis and discussion of the experiments presented in this paper focuses on usage trends such as the signature, viewing and editing patterns exhibited by the student cohort. The community building potential of wikis is discussed, highlighting the specific wiki features that can be used to foster a sense of community in a web-based learning environment. Finally, issues surrounding the development of web-based learning communities, which have emerged through the wiki study, are discussed and future directions are outlined. © 2006 Inderscience Enterprises Ltd.

A distributed database system is subject to site failure and link failure. This paper presents a reactive system approach to achieving fault tolerance in such a system. The reactive system concepts are an attractive paradigm for system design, development and maintenance because it separates policies from mechanisms. In the paper we give a solution using different reactive modules to implement the fault tolerant policies and the failure detection mechanisms. The solution shows that they can be separated without impact on each other; thus the system can adapt to constant changes in environments and user requirements.

View description>>

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

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

Propose: Preliminary study for implementing electronic health services in Iran as a developing country, presented in previous paper from the authors led us to design a blueprint including feasibility study, priority study and infrastructure design. Methods and Results: Feasibility of proposed electronic health services in previous paper obtained from determining enhancing and restricting parameters and Iranian information technology professionals opinions about importance and effect of these parameters in implementing each service. Priority study prepared a prioritized list of feasible services by two criteria (strong-weak point and opportunity) decision making model. In priority study, we used analytical hierarchy process (AHP) method and Expert Choice, as its tool, to prioritize feasible services. Infrastructure design presented some guidelines for implementing feasible services, regarding functional requirements of a distributed system such as electronic health system. In this step we designed multiplied sides infrastructure for electronic health system, consisted of services (repository of feasible services) and layers (designed according to OSI network model). Conclusion: In preliminary study and blueprint design we presented an adapted strategic plan for implementing electronic health services in developing country such as Iran, regarding their requirements and limits obtained from surveys on their workers, clients and IT professionals opinions.

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

Purpose: The purposes or this study were to (a) describe the prevention practices of nurse practitioners (NPs) regarding childhood obesity, (b) compare the practices of NPs by specialty, practice setting, and awareness of childhood obesity prevention guidelines, (c) identify relationships between prevention practices and demographic variables of NPs, and (d) examine the resources for and barriers to implementing prevention practices. Data sources: A convenience sample of 99 family NPs (FNPs) and pediatric NPs (PNPs) from the Intermountain area was used. Participants completed a questionnaire based on documented risk factors for childhood obesity as well as prevention guidelines developed by the American Academy of Pediatrics (AAP). Conclusions: NPs working in family practice or general pediatric practice settings were not consistently using the BMI-for-age index to screen for childhood obesity, as recommended by the AAP. However, they were teaching parents to promote healthy food choices and physical activity in their families. PNPs and FNPs working in a pediatric practice setting and NPs who were aware of prevention guidelines were more likely to perform several prevention strategies than FNPs working in a family practice setting and those who were unaware of guidelines. Major barriers to implementing childhood obesity prevention strategies included parental attitudes, the American lifestyle, and lack of resources for both the NP and the family. The main resources NPs used in preventing childhood obesity were a dietician, journal articles, and Web sites. Implications for practice: Although the majority of the NPs in this study reported being aware of childhood obesity prevention guidelines (73.7%), most were not consistently using BMI for age or monitoring children at increased risk for obesity. Because childhood obesity is escalating at such a rapid rate, it is critical that NPs working in family practice and pediatric practice settings take the necessary steps...

View description>>

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

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

Background: TATA box is one of the most important transcription factor binding sites. But the exact sequences of TATA box are still not very clear. Results: In this study, we conduct a dedicated analysis on the frequency distribution of TATA Box and its extension sequences on human promoters. Sixteen TATA elements derived from the TATA Box motif, TATAWAWN, are classified into three distribution patterns: peak, bottom-peak, and bottom. Fourteen TATA extension sequences are predicted to be the new TATA Box elements due to their high motif factors, which indicate their statistical significance. Statistical analysis on the promoters of mice, zebrafish and drosophila melanogaster verifies seven of these elements. It is also observed that the distribution of TATA elements on the promoters of housekeeping genes are very similar with their distribution on the promoters of tissue specific genes in human. Conclusion: The dedicated statistical analysis on TATA box and its extension sequences yields new TATA elements. The statistical significance of these elements has been verified on random data sets by calculating their p values. © 2006 Shi and Zhou: licensee Biomed Central Ltd.

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

Propose: In order to implement electronic health services in Iran with its own limits as a developing country, we performed preliminary study on the current status of Irans health system as a part of a strategic planning. Methods and Results: Mashhad health system (second populated city in Iran) was our case study. We defined four kinds of health units in the city including clinical units, laboratories, hospitals and management units of the system. List of problems were prepared through observing the system and face to face interviews with people in charge in those units. Problems were categorized by PIECES framework. Then a survey on clients and health workers opinions about found problem was performed to identify the importance and intensity of each problem in the each unit. The end results directed us to propose relevant electronic health services to satisfy system requirements. Conclusions: proposed requirement-based electronic health services, produced by preliminary study, open the way for second phase of our strategic planning for implementing electronic health services called blueprint design.

Distributed Denial of Service (DDoS) attacks have become one of the most serious threats to the information infrastructure. In this paper, we propose a new approach, Mark-Aided Distributed Filtering (MADF), to find the network anomalies by using a back-propagation neural network. The marks in the IP header that are generated by a group of IP traceback schemes called Deterministic Packet Marking (DPM)/Flexible Deterministic Packet Marking (FDPM) assist this process of identifying and filtering attack packets. MADF can detect and filter DDoS attack packets with high sensitivity and accuracy, thus providing high legitimate traffic throughput and low attack traffic throughput. © 2006 Inderscience Enterprises Ltd.

In the last a few yearsa number of highly publicized incidents of Distributed Denial of Service (DDoS) attacks against high-profile government and commercial websites have made people aware of the importance of providing data and services security to users. A DDoS attack is an availability attack, which is characterized by an explicit attempt from an attacker to prevent legitimate users of a service from using the desired resources. This paper introduces the vulnerability of web applications to DDoS attacks, and presents an active distributed defense system that has a deployment mixture of sub-systems to protect web applications from DDoS attacks. According to the simulation experiments, this system is effective in that it is able to defend web applications against attacks. It can avoid overall network congestion and provide more resources to legitimate web users. © troubador publishing ltd.

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

View description>>

In this paper, we consider applications of auditory display for representing audio system and audio signal characteristics. Conventional analytic representations of system characteristics, such as impulse response or non-linear distortion, rely on numeric and graphic communication. Alternatively, simply listening to the system under test can also reveal important aspects of its performance. Given that auditioning systems is so effective, it seems useful to develop higher-level auditory representations (auditory displays) of system performance parameters to exploit these listening abilities. For this purpose, we consider ways in which audio signals can be further transformed for auditory display, beyond the simple act of playing the sound.

View description>>

In this paper we develop examples of how the understanding of acoustic and audio phenomena can be enhanced through sonification, especially with a view to application in education. The term sonification refers to the process of converting data into non-speech audio, and is distinct from auralization in that the process does not aim to simulate an actual or imagined sound environment. Measurements of audio and acoustical systems are most commonly represented numerically and graphically, and these two methods each have distinct advantages. However, display of such data using sound not only conveys important information, but also may provide an experience of important aspects of the phenomenon under consideration. When used in an education context, this method of data display should improve listening skills. We demonstrate various data transformations that allow a sonification of acoustical measurements or phenomena to bring out features of interest. We also demonstrate more abstract sonifications (auditory graphs) that can be usefully applied to this context. Copyright © (2006) by the Australian Acoustical Society.

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

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

Sensor Networks have applications in diverse fields. They can be deployed for habitat modeling, temperature monitoring and industrial sensing. They also find applications in battlefield awareness and emergency (first) response situations. While unique addressing is not a requirement of many data collecting applications of wireless sensor networks it is vital for the success of applications such as emergency response. Data that cannot be associated with a specific node becomes useless in such situations. In this work we propose an addressing mechanism for event-driven wireless sensor networks. The proposed scheme eliminates the need for network wide Duplicate Address Detection (DAD) and enables reuse of addresses. © 2006 IEEE.

Technology-enabled business innovation presents the potential to structurally transform enterprise and industry practice, but uncertainty remains as to how such transformations might be managed. The search for higher returns from technology-enabled business innovation will inevitably lead to the adoption and exploitation of powerful, but disruptive technologies that bring with them higher levels of risk. Disruptive innovation is placed into context through the literature and through examples of past IT innovations with disruptive impact. This paper examines how organizations could obtain improved management of the adoption of potentially disruptive future generation Web technologies. The Business Innovation Technology Adoption Model (BITAM) is applied to emerging Web technologies to help identify the nature and extent of their potentially disruptive impact on business practice and management strategies so as to better enable mitigation of business risk.

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

This paper proposed a new approach for collecting, analyzing and visualizing co-authoring data of individuals. This approach can be used for understanding the academic collaboration and knowledge domain of individual researchers in a past period through repetitive co-published works. Particularly we extracted the co-authoring data from the DBLP which is one of the largest on-line Computer Science bibliographic databases available on the Internet. To help users to understand the academic collaboration and knowledge domain of individuals, we developed an InterRing visualizer which shows not only the weight of co-authorship of an individual with other researchers in particular academic year, but also the knowledge domain of the individual that was covered by his/her publications published in a past period.

This paper presents a clustering and visualization technique for analyzing dihedral angles of large protein sequences. The clustering is used for discovering and grouping those similar dihedrals while the visualization can display and navigate sequences of dihedral angles of several proteins as well as their clustered property. In order to visualize a very large sequence of hundred thousands of dihedral signals, we plot them on a spiral coordinate system. This spiral visualization ensures the linear distribution without distortion or interruption of a very long sequence of points. A clustering algorithm is also provided to group those dihedral signals into different clusters so that it can enhance the analysis process. Our system can also zoom to display a number of selected proteins interactively

This paper describes a space-efficient visualization model that automatically crawls through a website and visualizes its sitemap. This model can be used especially for displaying and navigating a very large website in a two-dimensional (2D) plane and/or a three-dimensional (3D) space. The 2D visualization employs EncCon layout algorithm to effectively visualize a very large number of pages and relations at once in which it utilizes the space to display more information. This technique also employs a focus+context navigation method to enable the exploration of large sites. Animation is provided to preserve the user's mental map while exploring the website hierarchy. The 3D visualization extends the 2D EncCon layout algorithm to a three-dimensional space which aims to provide a more realistic look and feel of the information.

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

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

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

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

Persuasive technology is the general class of technology that has the explicit purpose of changing human attitudes and behaviours. Persuasive technologies apply principles of social psychology in influencing people; principles of credibility, trust, reciprocity, authority and the like. Social psychologists have spent a great deal of effort over many years in trying to understand how attitude and behaviour change comes about, focusing on the effectiveness of human persuaders, and the persuasive power of messages delivered through non-interactive mass-media, such as newspapers or television. Harnessing the persuasive power of current interactive media, persuasive technology was recently identified as a separate research field, as evidenced by B.J. Foggâs first discussion of the domain1. Fogg characterises computers designed to persuade as the 5th major wave in computing2 . The scope of technologies that hold persuasive potential is broader than ICT alone, and includes persuasive product design and architectural design, yet the interactive nature of computers uniquely enables user-sensitive and user-adaptive responding, allowing persuasive messages to be tailored to the specific user in question, presented at the right place and at the right time, thereby heightening their likely persuasive impact.

View description>>

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

The objective of this paper is to investigate a novel design for local motion vectors (LMVs) of image sequences, which are often used in a digital image stabilization (IS) system. The IS technique removes unwanted shaking phenomenon in image sequences captured by hand-held camcorders. It includes two main parts such as motion estimation and compensation. Most of computation power occurs in the part of motion estimation. In order to reduce this complexity, an idea, which integrates an adaptive-threshold method and cellular neural networks (CNN) architecture, is designed to improve this problem. The design only implements the most important local motion estimation with the array size of 19×25 pixels. Experimental results with HSPICE simulation and CNNLM are shown that the proposed architecture fast searches the location of possible LVMs and has the capability of real-time operations. ©2006 IEEE.

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

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

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

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

View description>>

Telemedicine is now made more feasible with the advent of modern information and telecommunication technologies. Telemedicine is used in a variety of medical situations in several countries. Its use is widespread. However these systems need to be evaluated so as to know how they are performing in comparison to the traditional ways of offering health care services. Health care providers and policy makers need to know the efficiency and effectiveness of these systems so that the available resources are used in efficient and cost effective alternatives of health services. People around the globe have been using different frameworks to evaluate telemedicine systems. Most people are evaluating telemedicine on ad hoc basis. Not one methodology or framework is popular or is widely used for evaluations. Hence the results are not comparable. There is clearly a need for standard methodology or a framework. Lack of evaluation standards can impact the costs, effectiveness, access and efficiency of care provided to patients. As a result this paper proposes a unified framework by synthesising existing methodological frameworks. The proposed framework provides various measures and criteria for evaluating various telemedicine applications. The framework also provides key indicators at a base level for each criterion. The most important measures in this framework are access, cost, effectiveness and acceptability of care. It is expected that this framework will be a step towards standardisation of frameworks and it will help new and experienced evaluators, health care providers and policy makers. The proposed framework is broad so that it can be applied to any application of telemedicine and depending on the setting in a given organisation; application specific base indicators may be added or deleted for each criterion. ©2006 IEEE.

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

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

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

Transcription factor binding sites play an important role in the regulation of gene expression. This study develops a different computational approach to discover putative TFBSs in 17407 human promoters. 89 8-mer sequences are discovered from this research, including 12 new putative TFBSs. All these 12 putative TFBSs show peaks at the location upstream from TSS. 30 out of 89 sequences were also discovered by FitzGerald et al.(FitzGerald et al. 2004), 63 out of 89 sequences match the motifs discovered by Xie et al.

This paper took advantage of phylogenetic footprinting and statistical analysis to identify putative cis-regulatory elements in the promoters of human genes. Three organisms were investigated including human, mouse and drosophila melanogaster. 124 putative regulatory elements of length 8 were yielded from this research and they were grouped into 20 clusters. The investigation on the coexistence of these clusters in human gene promoters revealed that SP1, EGR and NRF-1 were the dominant clusters appearing in the combinatorial combination of up to five clusters. Gene Ontology (GO) analysis revealed that many of GO categories of transcription factors binding to these elements matched the GO categories of genes whose promoters contain these elements. ©2006 IEEE.

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

There has been a recent proliferation of multi-national, multi-institutional computer science education research exploring issues surrounding novice computer science student understanding.

Grounding robot perceptions 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 and effectively. Furthermore, a well grounded robot offers significant software engineering benefits since its behaviours can be developed with less effort, and even more importantly they can be debugged and tested on the fly.

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

TATA box is one of the most important transcription factor binding sites. But the exact sequences of TATA box are still not very clear yet. In this study, we conducted a dedicated analysis on the frequency distribution of TA TA Box and its extension sequences on human promoters. Sixteen TATA elements derived from TATA Box. motif, TATAWAWN, were classified into three distribution patterns: peak, bottom-peak and bottom. Fourteen TA TA extension sequences (up to two base extensions) were predicted to be the new TATA Box elements because of their high motif factors, which indicate their statistical significance. Statistical analysis on the promoters of mouse, zebrafish and drosophila melanogaster verified seven of these elements. It was also observed that the distribution of TATA elements on the promoters of housekeeping genes are very similar with their distribution on the promoters of tissue specific genes in human. © 2006 IEEE.

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

Distributed Denial of Service (DDoS) attacks has been a serious threat on security of the current Internet. Recently there is a trend that many DDoS attacks utilize Internet Relay Chat (IRC) infrastructures as the communication channels. In this paper we propose an Intrusion Surveillance System (ISS) to detect IRC-based DDoS attacks. The main functions of ISS are to observe network conditions, gather intelligence from distributed sources, and determine what potential attacks will likely happen. We give the detailed design of ISS in this paper. We also implement this system by using a new approach of text-based decision making - Distributed Preference-Based Surveillance (DPBS) algorithm. By experiments we demonstrate that this distributed algorithm can effectively identify potential IRC-based DDoS attacks based on the information from different locations. © 2006 IEEE.

Distributed Denial of Service (DDoS) attack has been identified as one of the most serious problems on the Internet. While much of the current research focus on DDoS countermeasures, little attention has been paid on DDoS modeling, which is one of the important aspects that can help provide better solutions against DDoS attacks. This paper proposes an analytical model for the interactions between DDoS attack party and defense party, which allows us to have a deep insight of the interactions between the attack and defense parties. Many refinements of the basic analytical model such as reinforcement of the defense party and loss in defense party are given in the paper, which suit for many real DDoS scenarios. Moreover, the applications of this model demonstrate that the model can precisely estimate the effectiveness of a DDoS defense system before it encounters different attacks and quantitatively estimate the optimal level of investment on DDoS defense system. Additionally, it can also be applied to model some other network security problems such as virus and spam defense. © 2006 IEEE.

Achieving an effective gait locus for legged robots is a challenging task. It is often done manually in a laborious way due to the lack of research in automatic gait locus planning. Bearing this problem in mind, this article presents a gait locus planning method using inverse kinematics while incorporating genetic algorithms. Using quadruped robots as a platform for evaluation, this method is shown to generate a good gait locus for legged robots.

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

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

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

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

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