The use of a machine learning approach with automatic feature selection for multi-class protein fold classification is studied. Neural networks are used to complete the task of protein fold classification, where each node is associated with a gate. The results show that the proposed architecture is effective in reducing the dimensionality of the data and enhancing the classification performance. The proposed technique allows the processing of more features from amino acid sequences.

In this paper, a recurrent compensatory neuro-fuzzy system (RCNFS) for identification and prediction is proposed. The compensatory-based fuzzy method uses the adaptive fuzzy operations of neuro-fuzzy systems to make fuzzy logic systems more adaptive and effective. A recurrent network is embedded in the RCNFS by adding feedback connections in the second layer, where the feedback units act as memory elements. In this paper, the RCNFS model is proved to be a universal approximator. Also, an online learning algorithm is proposed which can automatically construct the RCNFS. There are no rules initially in the RCNFS. They are created and adapted as online learning proceeds through simultaneous structure and parameter learning. Structure learning is based on the degree measure and parameter learning is based on the ordered derivative algorithm. Finally, the RCNFS is used in several simulations. The simulation results of the dynamic system model have shown that (1) the RCNFS model converges quickly; (2) the RCNFS model requires a small number of tuning parameters; (3) the RCNFS model can solve temporal problems and approximate a dynamic system. © 2004 Elsevier B.V.

The cellular neural network (CNN) is a powerful technique to mimic the local function of biological neural circuits for real-time image and video processing. Recently, it is widely accepted that using a set of CNNs in parallel can achieve higher-level information processing and reasoning functions either from application or biologics points of views. We introduce a novel framework for constructing a multiple-CNN integrated neural system called recurrent fuzzy CNN (RFCNN). This system can automatically learn its proper network structure and parameters simultaneously. In the RFCNN, each learned fuzzy rule corresponds to a CNN. Hence, each CNN takes care of a fuzzily separated problem region, and the functions of all CNNs are integrated through the fuzzy inference mechanism. Some on-line clustering algorithms are introduced for the structure learning, and the ordered-derivative calculus is applied to derive the recurrent learning rules of CNN templates in the parameter-learning phase. RFCNN provides a solution to the current dilemma on the decision of templates and/or fuzzy rules in the existing integrated (fuzzy) CNN systems. The capability of the RFCNN is demonstrated on the real-world vision-based defect inspection and image descreening problems proving that the RFCNN scheme is effective and promising. ©2005 IEEE.

Photometric stereo technique deals with the reconstruction of three-dimensional (3-D) shape of an object by using several images of the same surface taken from the same viewpoint but under illuminations from different directions. In this paper, we propose a new photometric stereo scheme based on a new reflectance model and the postnonlinear (PNL) independent components analysis (ICA) method. The proposed nonlinear reflectance model consists of diffuse components and specular components for modeling the surface reflectance of a stereo object in an image. Unlike the previous approaches, these two components are not separated and processed individually in the proposed model. An unsupervised learning adaptation algorithm is developed to estimate the reflectance model based on image intensities. In this algorithm, the PNL ICA method is used to obtain the surface normal on each point of an image. Then, the 3-D surface model is reconstructed based on the estimated surface normal on each point of image by using the enforcing integrability method. Two experiments are performed to assess the performance of the proposed approach. We test our algorithm on synthetically generated images for the reconstruction of surface of objects and on a number of real images captured from the Yale Face Database B. These testing images contain variability due to illumination and varying albedo in each point of surface of human faces. All the experimental results are compared to those of the existing photometric stereo approaches tested on the same images. The results clearly indicate the superiority of the proposed nonlinear reflectance model over the conventional Lambertian model and the other linear hybrid reflectance model.

In this paper, we propose a new pedestrian detection algorithm, and use it to develop a real-time pedestrian detection system. The pedestrian detection algorithm can be functionally partitioned into two parts: moving object segmentation and pedestrian recognition. In moving object segmentation, we segment the moving objects in the scene by modified temporal differencing method. This method combines general temporal differencing method with detection nets. In pedestrian recognition, we obtain multi-type wavelet templates from input images. Interest points are extracted from wavelet templates. Then, feature points are extracted by statistical method from interest point templates. Finally, these feature points are fed into a trained multilayer back-propagation neural network. The output of the neural network implies the result - pedestrian or non-pedestrian. From experiments, accuracy rate of recognition achieves 95%. We implement this algorithm in a real-time pedestrian detection system. The system can detect pedestrians in the scene in real time. The pedestrian detection rate is 92.58%. © 2005 TFSA.

View description>>
The accurate classification of protein structure is critical and essential for protein function determination in Bioinformatics and Proteomics. A reasonably high rate of prediction accuracy for protein structure classification has been achieved recently in coarse-grained protein class assignment according to their primary amino acid sequences, such as classifying proteins into four classes in SCOP. However, it is still quite a challenge for fine-grained protein fold assignment, especially when the number of possible folding patterns as those defined in SCOP is large. In our previous work, hierarchical learning architecture (HLA) neural networks have been used to differentiate proteins according to their classes and folding patterns. A better prediction accuracy rate for 27 folding categories was 65.5% which improves previous results by Ding and Dubchak with 56.5% prediction accuracy rate. The success of the protein structure classification depends heavily on the computational methods used and the features selected. Here combinatorial fusion analysis (CFA) techniques are used to facilitate feature selection and combination for improving prediction accuracy rate of protein structure classification. The resulting classification has an overall prediction accuracy rate of 87.8% for coarse-grained 4 classes and 70.9% for fine-grained 27 folding categories by applying the concept of CFA to our previous work using neural network with the HLA framework. These results are significantly higher than others and our previous work. They further demonstrate that the CFA techniques can greatly enhance the machine learning method (such as NN in the paper) in the protein structure prediction problem.

We present a new algorithm that polygonises some surfaces that self intersect, or have other non-manifold features such as separate sections that meet at points. Gradient information is used to resolve ambiguous polygonisations in plotting nodes. A line-stitching algorithm is discussed that allows for multiple polygons to be in a plotting node. We illustrate the algorithm with a number of surfaces that demonstrate its capabilities and limitations.

It has been suggested that constraining a natural language (NL) reduces the degree of ambiguity of requirement specifications written in that language. There is also a tendency to assume that an inescapable side effect of constraining a natural language is a subsequent reduction in its expressiveness. The primary objective of this paper is to describe a technique that we have developed for empirically measuring the expressiveness of a Constrained Natural Language (CNL) when used to specify the requirements in a particular application domain. Our simple yet practical and repeatable technique elucidates the individual contribution that each lexical entity of the CNL can make on the overall expressiveness of the CNL. This technique is particularly useful for designing new CNLs, as well as situations where tailoring or streamlining existing CNLs for particular application domains is needed.

Trust and trustworthiness plays a major role in conducting business on the Internet in service-oriented environments. In defining trust for service-oriented environments, one needs to capture the notation of service level, service agreement, context and timeslots. The same applies for reputation which is the opinion of the third party agents which is used in determining the trust and trustworthiness. Because of the complexity of the issues, and the fact that the trust and reputation are essentially concerns with the relationships, it is important to clearly define the notion of the trust relationships and notion of the reputation relationships. In this paper, therefore, we clear these definitions and we introduce a graphical notation for representing these relationships.

The growing development in web-based trust and reputation systems in the 21st century will have powerful social and economic impact on all business entities, and will make transparent quality assessment and customer assurance realities in the distributed web-based service oriented environments. The growth in web-based trust and reputation systems will be the foundation for web intelligence in the future. Trust and Reputation systems help capture business intelligence through establishing customer relationships, learning consumer behaviour, capturing market reaction on products and services, disseminating customer feedback, buyers opinions and end-user recommendations, and revealing dishonest services, unfair trading, biased assessment, discriminatory actions, fraudulent behaviours, and un-true advertising. The continuing development of these technologies will help in the improvement of professional business behaviour, sales, reputation of sellers, providers, products and services. In this paper, we present a new methodology known as CCCI (Correlation, Commitment, Clarity, and Influence) for trustworthiness measure that is used in the Trust and Reputation System. The methodology is based on determining the correlation between the originally committed services and the services actually delivered by a Trusted Agent in a business interaction over the service oriented networks to determine the trustworthiness of the Trusted Agent.

The growing development of web-based reputation systems in the 21st 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.

Traditionally, transactions were carried out face-toface, now, they are carried out over the Internet. The infrastructure for the above business and information exchange could be client-server, peer-to-peer or mobile network environments, and very often users on the network carry out interactions in one of three forms: Anonymous (No names are identified in the communication) Pseudo-anonymous (Nicknames are used in the communication) Non-anonymous (Real names are used in the communication) Incapability or a fraudulent practice could occur when the seller or business provider or buyer (the agents on the network) does not behave in the manner that is mutually agreed or understood, especially if published terms and conditions exist. This paper evaluates currently existing trustworthiness systems and points out that currently there is no existing standardized measurement system for Quality of Service and outlines the methodology that we have developed for this.

The recurrent network is embedded in the RCNFS by adding feedback connections in the second layer, where the feedback units act as memory elements. Also, an on-line learning algorithm is proposed to automatically construct the RCNFS. They are created and adapted as on-line learning proceeds via simultaneous structure and parameter learning. Finally, the RCNFS is applied in several simulations. The simulation results of the dynamic system modeling have shown that 1) the RCNFS model converges quickly; 2) the RCNFS model requires a small number of tuning parameters; 3) the RCNFS model can solve the temporal problems and approximate a dynamic system.

We propose a novel reflectance model for photometric stereo. It consists of the diffuse components and the specular components. Unlike the past methods, we do not need to separate the two components from the nonlinear reflection model. We use a unsupervised learning adaptation algorithm to estimate the reflectance model based on image intensities. At first, the technique of the post nonlinear independent components analysis (ICA) model is used to obtain the surface normal on each point of an image. Then, the 3D surface model can be reconstructed based on the estimated surface normal on each point of image by using the method of enforcing integrability. We test our algorithm on synthetically generated images for the reconstruction of surface of objects and on a number of real images captured from the Yale Face Database B. The results clearly indicate the superiority of the proposed nonlinear reflectance model over the Georghiades's approach and the Hayakawa's approach. © 2005 IEEE.

This paper presents a novel robust image stabilization (IS) technique to find out local motion vectors in the image sequences captured. Our technique is based on a Cellular Neural Network (CNN) algorithm, which tracks a small set of features to estimate the motion of the camera. Real-time and parallel analog computing elements are contained in the architecture of CNN. It is a regular two-dimensional array and connects with its neighborhood locally. To implement this algorithm on VLSI CNN, the adaptive-minimized threshold method is proposed to find quickly extract reliable motion vectors in plain images which are lack of features or contain large low-contrast area. Each size of CNN is set to 1/120 of an image. A background evaluation model is also developed to deal with irregular images which contain large moving objects. The experimental results are on-line available to demonstrate the remarkable performance of the proposed CNN-based motion technique.

This paper investigates a new room effect simulator with different quality of audio sound sources for 5.1-channel sound system. The audio effect relates its impulse response with different room-dimension. The multiband equalizer is designed to generate many kinds of music impression. We also modify the mono Dolby surround decoder into a simplified surround decoder so that the stereo room simulator can generate 5.1-channel surround outputs. All experiments are at a sampling rate of 44.1k Hz and 16 bits per sample. By the room effect simulator, we can get a full and a live listening experience. © 2005 IEEE.

Despite its critical importance to the process of systems development, requirements elicitation continues to be a major problem in both research and practice. This complex activity involving many different facets and issues is often performed badly and subsequently blamed for project failure and poor quality systems. In this paper we present a collaborative and combinational approach to requirements elicitation within a systems engineering framework, proposing the application of current research from other disciplines in areas related to requirements elicitation, such as software engineering and the social sciences, to a general systems engineering context. The work provides both researchers and practitioners with an approach to requirements elicitation for systems engineering that can be applied to real world projects to improve both the process and results, thereby increasing the overall chance of successful system development in terms of on schedule and on budget delivery, and satisfied customers.

The enterprise computer-based systems employed by the organisations of today can be extremely complex. Not only do they consist of countless hardware and software products from many varied sources, but they often span continents, piggybacking on public networks. These systems are essential for undertaking business and general operations in the modern environment, and yet the ability of organisations to control their evolution is questionable. The emerging practice of enterprise architecture seeks to control that complexity through the use of a holistic and top-down perspective. However, the toolsets already in me, are very much bottom-up by nature. To overcome the limitations of current enterprise architecture practices, the authors propose the use of the ABACUS methodology and toolset. The authors conclude that by using ABACUS to analyse software and enterprise systems, architects can guide the design and evolution of architectures based on quantifiable non-functional requirements. Furthermore, hierarchical 3D visualisation provides a meaningful and intuitive means for conceiving and communicating complex architectures.

The discipline of modelling and simulation (MaS) preceded artificial intelligence (AI) chronologically. Moreover, the workers in one area are typically unfamiliar with, and sometimes unsympathetic to, those in the other. One reason for this is that in MaS the formal tools tend to center around analysis and probability theory with statistics, while in AI there is extensive use of discrete mathematics of one form or another, particularly logic. Over the years however, MaS and AI developed many frameworks and perspectives that are more similar than their respective practitioners may care to admit. We will argue in this paper that these parallel developments have led to some myopia that should be over-come because techniques and insights borrowed from the other discipline can be very beneficial. © Springer-Verlag Berlin Heidelberg 2005.

In [Foo, et.al. 04] we re-visited the problem of converting action specifications into system constraints by re-examining it in the very simple setting of STRIPS, motivated by the simplicity of its simplicity as an action specification language. We showed how to extract action invariants, and then system laws, from STRIPS specifications. This was the consistency part of our method, and we deferred its adequacy to a later report. This paper provides the missing part, thus closing the circle. Here we show that the invariants extracted by our method can be tested by using them to complete partial specifications that may match those which were used as inputs to the extraction phase. Even when the match is incomplete there is interesting ontological information that can be inferred from it. Fixed point theory is used to account for some of the proposed algorithms.

In multi-agent setting agent teams often encounter conflicts in agents' plans and actions. This paper presents a cooperative negotiation model (ABCON) that allows agents in a team to appropriately negotiate various options in a hostile and dynamic fire world. It shows that negotiations explore the attitudes and behaviors that help agents to manage conflict constructively. It says that cooperative negotiation is guided by the agents' dynamic assessment of alternative actions given the different scenario conditions. © 2005 IEEE.

Many mechanisms have been developed to deliver only relevant information to the web users and prevent information overload. The most popular recent developments in the e-commerce domain are the user-preference based personalization and recommendation techniques. However, the existing techniques have a major drawback poor accuracy of recommendation on one-and-only items because most of them do not understand the items semantic features and attributes. Thus, in this study, we propose a novel Semantic Product Relevance model and its attendant personalized recommendation approach to assist Export business selecting the right international trade exhibitions for market promotion. A recommender system, called Smart Trade Exhibition Finder (STEF), is developed to tailor the relevant trade exhibition information to each particular business user. STEF reduces significantly the time, cost and risk faced by exporters in selecting, entering and developing international markets. In particular, the proposed model can be used to overcome the drawback of existing recommendation techniques

This paper presents the design and analysis of a claw pole/transverse flux motor (CPTFM) with soft magnetic composite (SMC) core and permanent magnet flux-concentrating rotor. Three-dimensional magnetic field finite element analysis is conducted to accurately calculate key motor parameters such as winding flux, back electromotive force, winding inductance, and core loss. Equivalent electric circuit is derived under optimum brushless DC control condition for motor performance prediction, and computer search techniques are applied for design optimization. All these computations and analyses have been implemented in a commercial software ANSYS for development of the SMC CPTFM prototype.

Smart Sensor Networks are one of the most exciting research areas in information technology today; their potential for business applications is vast, but yet to be realised. In this paper we argue that intelligent sensor networks can only reach their potential for business applications if the network is grounded so as to support meaningful information sharing and knowledge generation as the basis for an effective business decision model. Our work is based on the idea that sensors extract information from their environment which, typically, must be fused with other sensor data and network knowledge so that effective business decision making is supported.

In almost every interaction the trusting peer might fear about the likelihood of the loss in the resources involved during the transaction. This likelihood of the loss in the resources is termed as Risk in the transaction. Hence analyzing the Risk involved in a transaction is important to decide whether to proceed with the transaction or not. If a trusting peer is unfamiliar with a trusted peer and has not interacted with it before in a specific context, then it will ask for recommendations from other peer in order to determine the trusted peer?s Riskiness value or reputation. In this paper we discuss the process of asking recommendations from other peers in a specific context and assimilating those recommendations according to its criteria of the interaction in order to determine the correct Riskiness value of the trusted peer.

Risk is associated with almost every activity that is undertaken on a daily life. Risk associated with Trust, Security and Privacy. Risk is associated with transactions, businesses, information systems, environments, networks, partnerships, etc. Generally speaking, risk signifies the likelihood of financial losses, human casualties, business destruction and environmental damages. Risk indicator gives early warning to the party involved and helps avoid deserters. Until now, risk has been discussed extensively in the areas of investment, finance, health, environment, daily life activities and engineering. However, there is no systematic study of risk in Decentralised communication, which involves e-business, computer networks and service oriented environment. In this paper, we define risk associated with trusted communication in e-business and e-transactions; provide risk indicator calculations and basic application areas.

Every activity has some Risk involved in it. Analyzing the Risk involved in a transaction is important to decide whether to proceed with the transaction or not. Similarly in Peer-to-Peer communication analyzing the Risk involved in undertaking a transaction with another peer too is important. It would be much easier for the trusting peer to make a decision of proceeding a transaction with the trusted peer if he knows the Risk that the trusted peer is worthy of. In this paper develop and propose such a methodology which allows the trusting peer to rate the trusted peer in terns of Risk that he deserves after the transaction is over.

Decentralized transactions are increasingly becoming popular. These transactions resemble the early forms of the internet and in many ways are regarded as the next generation of the internet. The result will be that this e-commerce transactions approach will shift to peer-to-peer communications rather than client-server environment. However, these peer-to-peer communications or decentralized transactions suffer from some disadvantages, which includes the risk associated with each transaction. This paper focuses on the factors that influence Risk in a decentralized transaction.

In real situation, gathering enough training samples is difficult and expensive. Assumption of enough training samples is usually not satisfied for high dimensional data. Small training sets usually cause Hughes phenomenon and singularity problems. Feature extraction and feature selection are usual ways to overcome these problems. In this study, an optimal classification system for classifying hyperspectral image data is proposed. It is made up of orthonormal coordinate axes of the feature space. Classification performance of the classification system is much better than the other well-known ones according to the experiment results below. It possesses the advantage of using fewer features and getting better performance. © Springer-Verlag Berlin Heidelberg 2005.

The texture boundary detection is based on the first- and second-order features to model the pre-attentive stage of a human visual system. This system is implemented by a cellular neural network universal machine (CNN-UM) with 3×3 templates to approximate desired filter transfer functions. The system design can process a 64×64 gray-scale image. The proposed algorithm can successfully be performed by CNN-UM and detect the texture boundary in a given image.

CNNs present the behaviors which are most similar to the retina of human's eyes, and HIP presents architecture which is also most similar to the distribution of cells on the retina.

This paper proposes a novel approach for texture classification by feature extraction based on cellular neural networks (CNN's) and an intelligent arrangement in the design or exact using of the templates in CNN's. This paper also gives a two-way processing mechanism including the analysis of features extracted from the output of CNN's mapping and a selective training step for obtaining the specific templates in CNN's by genetic algorithms (GA's) for more complicated texture patterns. In this paper, we introduce a one dimensional feature curve as well to indicate the characteristics of original texture patterns from the mapping of the output of CNN's for the latter texture classification. The method introduced in this paper could adaptively choose an appropriate processing procedure for the specific issues towards in specific texture patterns. We finally divide our experiments into two sections, for simple and advanced problems in texture classification. Our experimental results demonstrate the valid template training and at the same time show a satisfactory classification outcome in both defined texture problems.

In this study, a computational model for chromatic texture segregation is developed. The model attempts to simulate the visual processing characteristics by mimicking the visual perception. According to Hering's opponent theory, we deal with color information in a color space with three opponent axes. The algorithm extracts 1st-order features by a Gaussian filter and 2 nd-order features by a set of Gabor filters as so called Gabor wavelets. The hybrid-order features are combined at a common site to detect the boundary. The model is very intuitive and physiological relevant such that it reserves opportunities for further approaches.

During the past years, the public security has become an important issue, especially, the safe manipulation and control of various vehicles. Maintaining high cognition is particularly important for the drivers behind the steering wheel. It requires an optimal estimation system to online continuously detect drivers' cognitive state related to abilities in perception, recognition, and vehicle control. In this paper, we proposed an EEG-based alertness estimation system with automatic feature selection mechanism. The independent component analysis (ICA) is used first to decompose the measured electroencephalogram (EEG). Then, a time-frequency analysis is performed to evaluate the time-frequency characteristic of each ICA component. We also proposed a new adaptive feature extracting mechanism for selections of frequency bands and ICA components. Different ranges of the alpha rhythm of subjects can be evaluated by the adaptive feature extracting mechanism according to the correlation coefficient between the ICA time-frequency response and the driving performance. The extracted features are then trained both by linear regression model and Self-cOnstructing Neuro-Fuzzy Inference Network (SONFIN) for the estimation of driving performance. The training and testing results of SONFIN are 96% and 91%, while the results of linear regression model are 90% and 85%, respectively. It demonstrates that the proposed adaptive feature extracting mechanism can achieve a great performance in alertness estimation with frequency band and component selection. © 2005 IEEE.

Traffic fatalities in recent years have become a serious concern to our society. Accidents caused by drivers' drowsiness have a high fatality rate due to the decline of drivers' abilities in perception, recognition, and vehicle control abilities while sleepy. Preventing such an accident requires a technique for detecting, estimating, and predicting the level of alertness of a driver and a mechanism to maintain the driver's maximum performance of driving. This paper proposed a system that combines electroencephalogram (EEG) power spectra estimation, independent component analysis and fuzzy neural network models to estimate drivers' cognitive state in a dynamic virtual-reality-based driving environment. Experimental results show that the quantitative driving performance can be accurately and successfully estimated through analyzing driver's EEG signals by the proposed system.©2005 IEEE.

A novel 2D to 3D effect image conversion architecture integrated image segmentation system and depth estimation is presented. Its objective is to describe the technique used to generate stereo pair images starting from a single image source (a view-point) and its related depth map. The conjunction between segmented image and depth map allows reconstructing artificially the binocular view producing a 3D effect depending on screen dimension and image resolution. The system consists of an on-line ICA mixture model that performs image segmentation and depth estimation method to obtain the depth information of image. The proposed system is capable to perform automatic multilevel segmentation of images, based on depth information obtained by the image depth estimation method. The system does not reconstruct the real 3D coordinates of any object inside the scene, but simply assigns the most comfortable shift to the source points to give a 3D-entertainment to the viewer. A simple smoothing filtering technique adaptively resolves the occlusions generated by shifting of the source points without introducing visible and/or annoying artifacts.

The classification of protein structures is essential for their function determination in bioinformatics. The success of the protein structure classification depends on two factors: the computational methods used and the features selected. In this paper, we use a combinatorial fusion analysis technique to facilitate feature selection and combination for improving predictive accuracy in protein structure classification. When applying these criteria to our previous work, the resulting classification has an overall prediction accuracy rate of 87% for four classes and 69.6% for 27 folding categories. These rates are significantly higher than our previous work and demonstrate that combinatorial fusion is a valuable method for protein structure classification. © 2005 IEEE.

As a rapidly growing field, Autonomic Computing is a promising new approach for developing large scale distributed systems. However, while the vision of achieving self-management in computing systems is well established, the field still lacks a commonly accepted definition of what an Autonomic Computing system is. Without a common definition to dictate the direction of development, it is not possible to know whether a system or technology is a part of Autonomic Computing, or if in fact an Autonomic Computing system has already been built. The purpose of this paper is to establish a standardised and quantitative definition of Autonomic Computing through the application of the Quality Metrics Framework described in IEEE Std 1061-1998 [1]. Through the application of this methodology, stakeholders were systematically analysed and evaluated to obtain a balanced and structured definition of Autonomic Computing. This definition allows for further development and implementation of quality metrics, which are project-specific, quantitative measurements that can be used to validate the success of future Autonomic Computing projects.

This paper describes the development of movement-oriented personas and scenarios for representing multiple users of an interactive, immersive environment, designed as an artistic work for a public space. Personas and scenarios were integrated into a user interaction script and linked to a set of movement schemas using Labanotation for group choreography. Enactment of the script within a prototype environment enabled the designers to experience the aesthetic and kinaesthetic qualities of the work, as well as the social interactional aspects of the user experience. This ensured that the experience of those visiting the exhibition was always central to the design process

With the ever-growing pace of technological advancement, computer software is required to become increasingly complex to meet the demands of today's leading edge technologies, and their applications. However, fulfilling this requirement creates new, previously unknown, problems pertaining to non-functional properties of software. Specifically, as the software complexity escalates, it becomes increasingly difficult to scale the software in order to cope with the sometimes overwhelming demand created by system growth. It is therefore essential to have processes for addressing the issues associated with scalability that arise due to the complexity in software systems. In this paper we describe an approach aimed at fulfilling the need for such processes. A combination of Object-Z and temporal logic is used to create an architectural description open to further analysis. We also demonstrate the practicality of this methodology within the context of the coordinated adaptive traffic system (CATS).

Having come of age in the last decade, the use of architecture to describe complex systems, especially in software, is now maturing. With our current ability to describe, represent, analyse and evaluate architectures comes the next logical step in our application of architecture to system design and optimisation. Driven by the increasing scale and complexity of modern systems, the designers have been forced to find new ways of managing the difficult and complex task of balancing the quality trade-offs inherent in all architectures. Architecture-based optimisation has the potential to not only provide designers with a practical method for approaching this task, but also to provide a generic mechanism for increasing the overall quality of system design. In this paper we explore the issues that surround the development of architectural optimisation and present an example of heuristic-based optimisation of a system with respect to concrete goals.

Premature and ill term babies born in metropolitan and regional Australia are monitored and supported by a range of medical devices within Neonatal Intensive Care Units (NICUs) or Special Care Nurseries. Information produced by these devices is in a range of formats making data transmission infrastructures complex. This paper details case study based web service framework research for the transmission of physiological data for local and remote Neonatal Intensive Care. This framework enables real-time physiological data collected from medical monitors and ventilators attached to the baby to be encoded in XML and transmitted via the use of a physiological log web service. The key contribution of this significant research is the infrastructure providing a mechanism for Neonatologists to receive information directly from a regional hospital, thereby preventing, in some cases, the immediate need to move the baby. This paper further describes the application of that architecture to a specific pilot within the NICU at Nepean Hospital, Penrith Australia. © 2005 IEEE Web Services, XML, Health Informatics,.

The care of premature and ill term babies born in regional Australia differs considerably from those born in metropolitan areas for without access to a Neonatologist, the baby must be moved to another hospital with Neonatal Intensive Care Unit (NICU) facilities. This paper details the Bush Babies Broadband project that aims to address this need by significantly improving the quality of treatment for babies born in regional and remote areas by providing the first on-demand virtual NICU architecture in Australia, Real-time data collected from medical monitors and ventilators attached to the baby, audiovisual streams and static physiological data such as x-ray images are transmitted to the consulting Neonatologist to gain a better picture of the patient's condition than is currently available. The key contribution of this significant research is the infrastructure providing a mechanism for Neonatologists to receive information directly from a regional hospital, thereby preventing, in some cases, the immediate need to move the baby. A key benefit of this framework is that it is available to link regional hospitals with the supporting NICU Neonatologist 'on demand' eliminating the need to establish permanent point to point connections. This paper further describes the application of that architecture to a specific pilot connecting the Bathurst regional hospital with Neonatologists within the NICU at Nepean Hospital, Penrith Australia. © 2005 IEEE.

The provision of Neonatal Intensive Care is impacted by the lack of centralised monitoring systems within infant ICUs and the inability for Neonatologists to view data from devices attached to premature babies born in regional and remote hospitals. While web services provide a platform and language independent environment to transport numeric data streams, they must be encoded in XML, increasing the numeric data stream size considerably and thereby impacting its transmission time and the web service performance. This research assesses compression performance on XML documents containing physiological data streams to investigate the conditions where web service performance can be improved through the compression of XML numeric data streams. The compressors are applied to several XML physiological data streams output by a neonatal monitoring device. A key benefit of this research is its specific focus on numeric data streams within web services. © 2005 IEEE.

We use an information theory approach to investigate the role of mutation on Genetic Algorithms (GA). The concept of solution alleles representing information in the GA and the associated concept of information density, being the average frequency of solution alleles in the population, are introduced. Using these concepts, we show that mutation applied indiscriminately across the population has, on average, a detrimental effect on the accumulation of solution alleles within the population and hence the construction of the solution. Mutation is shown to reliably promote the accumulation of solution alleles only when it is targeted at individuals with a lower information density than the mutation source. When individuals with a lower information density than the mutation source are targeted for mutation, very high rates of mutation can be used. This significantly increases the diversity of alleles present in the population, while also increasing the average occurrence of solution alleles.

The data mining inspired problem of finding the critical, and most useful features to be used to classify a data set, and construct rules to predict the class of future examples is an interesting and important problem. It is also one of the most useful problems with applications in many areas such as microarray analysis, genomics, proteomics, pattern recognition, data compression and knowledge discovery. Expressed as κ-Feature Set it is also a formally hard problem. In this paper we present a method for coping with this hardness using the combinatorial optimisation and parameterized complexity inspired technique of sound reduction rules. We apply our method to an interesting data set which is used to predict the winner of the popular vote in the U.S. presidential elections. We demonstrate the power and exibility of the reductions, especially when used in the context of the (α β)κ-Feature Set variant problem. Copyright © 2005, Australian Computer Society, Inc.

The existing Intrusion Detection Systems often generate alerts that represent only a sub attack of the attack, which the attacker is trying to accomplish. There is no work previously been carried out to implicitly link alerts together to discover attack plans from generated alerts. This paper proposes the system frame-work for behavior driven dynamic visual intrusion detection system that can be used to find out implicit relationships among alerts and discover attack plans which consist of smaller attacks, carried out in some particular sequential order. The paper also talks about how dynamic visualization along with the static visualization can be used for the visualization of alert and attack structures.

Building on traditional ethnographic techniques, we investigated the contents of people's bags, seeking traces of planning, decision making and other social practices that people rely on to construct and maintain relations between particular mobile objects and their particular mobile lives. The research contributes to the development of novel methods for researching mobile practices and its initial findings question assumptions about information use and storage, and about the personalisation of mobile device and services.

IT adoption within SMEs has been covered extensively within literature, most of which have considered IT adoption from narrow perspective such as drivers and barriers of IT adoption. IT adoption is better defined as a process which involves organisation and its components, stakeholders external to the organisation, and interactions within organisation and between organisation and its stakeholders. This paper uses multi perspective in IT adoption to build model of IT adoption. A field study involving 35 Indonesian SMEs was conducted in the form of semi structured interviews. The result from this field study were analysed and used to refine the proposed model.

Although within the information systems literature reports of these types of failure can be found but little is known about the aftermath of failure within SMEs. This case study presents the actions taken by two Indonesian SMEs who had to face with the failure of their web catalogue systems. The notion of IS failure used in this paper is a combination of expectation failure and termination failure.

The distribution and coordination of policies is often overlooked but is crucial to the scalability of dynamic, personalised services. In this work we partition an Abstract Syntax Tree of the policies to determine the responsibility of different management nodes in a geographically segregated network (i.e. management by delegation). This partitioning is combined with IN/OUT set analysis to determine the required coordination for policy enforcement of complex policies with inter-dependencies. Our simulation results show that this approach is promising, as higher decision loads can be readily handled by further sub-dividing of the network.

Many existing management systems are not evolutive or adaptive, leading to multiplicity over time and increasing the management burden. Policy-based management approaches may assist in making networks less complex and more automated, but to date they have not yet been able to evolve to support new service sets or provide the capacity for differentiation. We present the architecture for a policy-based system named Pronto that helps to deal with these issues. Layered network and service models are built above an extensible virtual device model that supports heterogenous management interfaces. Interchangeable management components provide the basic building blocks to construct logical services. The integrated policy-driven service definition language automates the management of the services in a manner that is adaptive, dynamic and reactive to improve the users overall service experience.

We now extend this work to support more complex policies containing control flow logic and looping, which are part of the PRONTO policy language. Early simulation results demonstrate the potential performance and scalability characteristics of this framework.

Lack of efficient catalogue management services in e-commerce system with enough and exact information about the orders and weakness in search methods for finding the commodities decreases the customer trend for using these systems. Investigating the results of customers' trend to e-commerce systems directed us to present a new method in customer-supplier relationship in these systems. In this paper we present a web-based application for customer-supplier relationship which can embed to a CRM system as a service. The proposed service manages the requirements identification, using SCG(Standard Classification of Goods) for implementing the automated requirements identifier. This system informs the suppliers about the requested orders in specific method. In this method system identifies the industry of supplier with SCI (standard Classification of Industries) and submits the received orders. Suppliers can present their proposal with answer the determined multi choice questions and system measures the proposal score and if it will be more than the determined negotiation ratio, service begins to negotiate with them to improve their proposals according to other proposals participated in this competition.

'If you don't see the Internet as an opportunity, it will be a threat.' (Blair 1999). Putting "e" in health services imposes some essential requirements to the system. Using some system engineering methodologies for determining the blueprint of our development is required before diving in implementation. To create a mathematical method for implementing electronic health services in developing countries, we chose Mashhad health system as our case study, and designed our survey in three steps: Primary investigation, Feasibility study and Priority study. Primary study consists of problem finding based on PIECES (Talaei-Khoei 2004) framework, then using statistical analysis based on workers and clients' opinions, we determined important and intensive problems in each unit. The next step in this survey is feasibility study, at first; in this step we proposed the essential services for solving the found problems in primary study. We also have defined several enhancing and restricting parameters based on governmental technical reports and collected the statistical data on professionals' opinions. Service feasibility identification is made through considering the effect of enhancing and restricting parameters on it. Finally, applying Analytical Hierarchy Process method for strong-weak point and opportunity as our two-criteria problem, the priority of feasible services was set. The result of this survey is determining the prioritized feasible services to be implemented in Iran as a developing country.

Recollecting memories is an important everyday activity, which can be supported in an Ambient Intelligent environment. For optimal support cues are needed that make people reconstruct their memories. The cue category that is most suitable for an Ambient Intelligent environment concerns physical objects, more specifically souvenirs. This paper shows that personal souvenirs are suitable for usage in an Ambient Intelligent recollecting application.

With the fast growth of e-commerce, product reviews on the Web have become an important information source for customersý decision making when they plan to buy products online. As the reviews are often too many for customers to go through, how to automatically classify them into different semantic orientations (i.e. recommend/not recommend) has become a research problem. Different from traditional approaches that treat a review as a whole, our approach performs semantic classifications at the sentence level by realizing reviews often contain mixed feelings or opinions. In this approach, a typical feature selection method based on sentence tagging is employed and a naïve bayes classifier is used to create a base classification model, which is then combined with certain heuristic rules for review sentence classification. Experiments show that this approach achieves better results than using general naïve bayes classifiers.

While most EEG based Brain-Computer-Interfaces (BCIs) employ machine learning algorithms for classification, we propose to utilize source localization procedures for this purpose. Although the computational demand is considerably higher, this approach could allow the simultaneous classification of a multitude of conditions. We present an extension of Independent Component Analysis (ICA) - based source localization that is fully automatic, and apply this method to the classification of EEG data generated by imaginary movements of the right and left index finger. The results demonstrate that source localization provides a viable alternative to machine learning algorithms for BCIs. © 2005 IEEE.

Sensorless permanent magnet synchronous motor (PMSM) drive systems have become very attractive due to their advantages, such as the reduction of hardware complexity and hence the reduced system cost and increased reliability. In order to accurately determine the rotor position required for correct electronic commutation, various methods have been proposed. Among them, the most versatile makes use of the structural and/or magnetic saturation saliencies of the PMSM. This paper presents a non-linear model for PMSMs with the saliencies. The phase inductances of a PMSM are measured and expressed by Fourier series at different rotor positions according to their patterns. The dynamic performance of the PMSM is simulated and compared with that based on a model without considering saliency to verify the effectiveness of the proposed model.

This paper proposes a new economic load dispatch model that considers cost coefficients with uncertainties and the constraints of ramp rate. The uncertainties are represented by fuzzy numbers, and the model is known as fuzzy dynamic economic load dispatch model (FDELD). A novel hybrid genetic algorithm with quasi-simplex techniques is proposed to handle the FDELD problem. The algorithm creates offspring by using generic operation and quasi-simplex techniques in parallel. The quasi-simplex techniques consider two potential optimal search directions in generating prospective offspring. One direction is the worst-opposite direction, which is used in the conventional simplex techniques, and the other is the best-forward direction, which is a ray from the centroid of a polyhedron whose vertexes are all the points but the best one towards the best point of the simplex. In addition, in order to reserve more fuzzy information, the fuzzy number ranking method is used to optimize the cost function, avoiding the lost some useful information by getting /spl lambda/-level set. The experimental study shows that FDELD is more practical model; the algorithm and techniques proposed are very efficient to solve FDELD problem.

Since it is not possible to identify or to create a single method that is appropriate for all situations, the need for a focussed requirements engineering method (REM) necessitates the search for a mechanism that will support the flexible creation of a number of tailored REMs from a single base. Using a repository of reusable method components, it is possible to use the techniques espoused by the method engineering community to construct an appropriate REM that is well-suited to the particular system or application development endeavour under consideration. One particular example is used to illustrate this approach that of the OPEN Process Framework (or OPF).
