IEEE International Workshop on Networked Appliances

作者： Y. Tajika A. Sawada M. Minoh T. Kamae Toshiba Corporate R&D Center / Graduate School of Informatics Kyoto University JAPAN Academic Center for Computing and Media Studies Kyoto University Kyoto JAPAN Science and Technology Laboratories of Image Information Tokyo JAPAN

We propose a novel scheme for a service production using service scenario and its control scheme, which works with a set of distributed functions offered from networked appliances on a home network. Firstly, basic ideas for the service scenario control, which is designed with a network-oriented MVC model and which sits on the dynamic function discovery/negotiation mechanism, are presented. Secondly, the architecture for the scenario control worked with the AMIDEN architecture [M. Minoh, et al. (2001)] and its description is discussed. On the architecture, functions are dynamically connected by the mechanism of the dynamic function discovery firstly, then characteristics of the functions are spontaneously configured by the parameter negotiation on the topology. On top of that, the service model is configured by parsing the service scenario which is statically described, the characteristics of the functions, and its topology which are dynamically configured from the network formation. Finally, from the initial study, we have resulted that the scheme is very much flexible for the service provider to design and create a distributed object-oriented program by using several functions without any knowledge of the function details in advance, and also flexible for the appliance designer to implement a function unit without a condition and a limitation for the integrated service, since each function and each scenario is allowed to be designed separately using generic framework and an appliance service is configured only with the proposed service scenario description sit on the AMIDEN architecture.

Herein, we propose a new Markov random field (MRF) image segmentation model which aims at combining color and texture features. The model has a multi-layer structure: Each feature has its own layer, called feature layer, where an MRF model is defined using only the corresponding feature. A special layer is assigned to the combined MRF model. This layer interacts with each feature layer and provides the segmentation based on the combination of different features. The uniqueness of our algorithm is that it provides both color only and texture only segmentations as well as a segmentation based on combined color and texture features. The number of classes on feature layers is given by the user but it is estimated on the combined layer. © 2002 IEEE.

On the difference between polynomial-time many-one and truth-table reducibilities on distributional problems 18th

In this paper we separate many-one reducibility from truth-table reducibility for distributional problems in DistNP under the hypothesis that P ≠ NP. As a first example we consider the 3-Satisfiability problem (3SAT) with two different distributions on 3CNF formulas. We show that 3SAT using a version of the standard distribution is truth-table reducible but not many-one reducible to 3SAT using a less redundant distribution unless P = NP. We extend this separation result and define a distributional complexity class C with the following properties: (1) C is a subclass of DistNP, this relation is proper unless P = NP. (2) C contains DistP, but it is not contained in AveP unless DistNP Í AveZPP. (3) C has a £mp-complete set. (4) C has a £ttp-complete set that is not £mp-complete unless P = NP. This shows that under the assumption that P 6 ≠ NP, the two completeness notions differ on some non-trivial subclass of DistNP. © Springer-Verlag Berlin Heidelberg 2001.

School of Computing Engineering and Technology University of Sunderland Informatics Centre Sunderland SR6 ODD United Kingdom University of Detroit Mercy United States University of Manchester Institute of Science and Technology Manchester United Kingdom University of York York United Kingdom Professional Engineers Ontario Ontario Canada

The prime aim of the workshop was to provide a forum to consider the global dimensions of a Software Engineering profession and determine the relevance and usefulness of an initiative concerning the harmonization of professional standards which had been produced under the auspices of the International Federation of Information Processing. In particular the workshop addressed: the current situation with regard to certification and/or licensing in different countries, the drivers and constraints regarding Software Engineering Professionalism, the extent to which world-wide Software Engineering Professionalism is achievable (particularly in the light of IFIP's proposals regarding harmonization), and possible strategy(ies) that would assist in achieving such world-wide Software Engineering Professionalism. A pre workshop survey was carried out at the conference and the results of this are reported. The two staged operation and results of the workshop are then detailed. Initial position statements are summarised and the conclusions from the four separate subgroups that operated within each of the two stages are reported. Finally the major points from a general discussion on what the future goals and strategies for achieving a recognised profession should be are presented followed by the overall conclusion of the workshop participants. © 2001 Kluwer Academic Publishers.

The development of the Internet and the World Wide Web presents both Information Systems professionals and business managers with many new ethical problems. It is therefore, necessary to teach students about professional issues. This paper looks at how Professional Issues entered the Higher Education curriculum during the last decade. In particular we present the experience gained within the school of informatics and Multimedia technology at the University of North London through the integration of case studies for the Professional Issues part of the In-Course-Assessment (ICA) of a Software Engineering module. The case studies fulfil one of the two core capabilities covered in the module. The marking scheme and two different resolutions to the ethical dilemma posed in one of the scenarios (case studies) reached by particular students are presented together with our conclusion and indications of further action and research.

Recent research into distortion-oriented display (DODs) and non-linear magnification techniques has considered extending their application to large three-dimensional datasets. Inherent properties of three-dimensional datasets introduce some difficulties that do not occur in 2D environments. This paper considers the Occlusion Problem-that of context data hiding, or occluding, some or all of the data within an area of focus. A novel solution to this problem is proposed, namely the use of non-geometric distortions combined with geometric distortions, producing a three-dimensional distortion-oriented display that reduces obfuscation of data within the area of focus. An implementation of these techniques is developed, and its application to a small number of 3D datasets is examined as proof of concept.

Strategic change stemming from e-commerce: implications of multi-agent systems on the supply chain

引用

Strategic Change 2001年第3期10卷 139-149页

作者： Cohen, Marcel Stathis, Kostas The Management School Imperial College of Science Technology and Medicine London UK GBR United Kingdom Intelligent & Distributed Systems Department of Computing School of Informatics City University London United Kingdom

Electronic commerce (e-commerce) raises a number of interesting business and technical issues. This paper addresses one important combination of business and technical issues — the implications of multi-agent systems on the supply chain. Multi-agent systems give rise to a new approach of developing information systems where problems of various forms, ranging from complex computational tasks to a requirement of specific information, are solved by those software components best suited to do so. The operational and strategic consequences of multi-agent systems are examined. Copyright © 2001 John Wiley & Sons, Ltd. Copyright © 2001 John Wiley & Sons, Ltd.

The amount of information available on the Internet is currently growing at an incredible rate. However, the lack of efficient indexing is still a major barrier to effective information retrieval on the web. This paper presents the design of an intelligent agent for content-based indexing and retrieval of relevant documents from a large collection such as the Internet. The agent aims at improving the quality of retrieval by capturing the semantics of the documents. It performs the conventional keyword based indexing and introduces a thematic relationship between parts of text using Natural Language Understanding and a linguistics theory called Rhetorical Structure Theory. The agent described in this paper will be implemented and compared against several indexing systems. It is expected to produce a satisfactory improvement over existing techniques. © 2000 IEEE

Metabuilder: The diagrammer’s diagrammer

A software tool named MetaBuilder is described. MetaBuilder’s purpose is to enable the rapid creation of computerised diagram editing tools for structured diagrammatic notations. At its heart is an object-oriented, graphical metamodelling technique - a diagrammatic notation for describing other diagrammatic notations. The notation is based upon the concept of a mathematical graph consisting of nodes and edges. Construction of a "target tool" proceeds by drawing a metamodel of the target notation. Items in the target notation are modelled as "classes" and the syntax of the target notation such as connectivity between elements are expressed as "relationships" between the classes. Once the metamodel is complete, a new tool can be generated automatically. Thus the time to develop such notation specific drawing tools can be dramatically reduced. As the design of a piece of software can be expressed diagrammatically, the MetaBuilder software can be used to build itself!. © Springer-Verlag Berlin Heidelberg 2000.
