Taschenbuch. Condición: Neu. Neuware -Die moderne Werkstofftechnologie ist dadurch gekennzeichnet, daß sie in weit größerem Maße, als es früher möglich schien, metastabile Zustände für die Herstellung von Legierungen und eine damit verbundene Gefüge-Optimierung einsetzen kann. Beispiele sind das mechanische Legieren oder etwa die Erstarrung aus tief unterkühlten Schmelzen. Die Verwendung ungewöhnlicher Tie gelmaterialen (z. B. der Aerogele), behälterfreie Verfahren oder das Erschmelzen unter Schwere losigkeit gestatten neue Einblicke, neue Anwendungsmöglichkeiten und weiteres Entwicklungs potential auf sehr breiter Front, auch in Richtung praktischer Fragestellungen. Weiterhin ist an zumerken, daß die moderne rechnerische Simulation von Gieß- und Erstarrungsvorgängen insbe sondere in der erstarrungstechnologischen Industrie einen Entwicklungsschub hervorruft, der auf einer gesunden theoretischen Basis aufbaut. Diese Entwicklung führt zu innovativen Werkstoffen und neuartigen Bauteilen, welche beide unter Nutzung ebenfalls entsprechend modifizierter Pro zeßtechniken entstehen. Die dafür erforderliche theoretische Grundlage profitiert insbesondere von einem Zusammenwirken mehrerer wissenschaftlicher Disziplinen. Die organisatorische und finanzielle Grundlage für eine solche interdisziplinäre Zusammen arbeit wurde 1993 durch die Einrichtung des Graduiertenkollegs 'Schmelze, Erstarrung, Grenz flächen' geschaffen. Das Kolleg wurde begleitet von einer Vorlesungsreihe, die die Fachgebiete der beteiligten Institute, ihrer Stipendiaten und Kollegiaten widerspiegelt. Von der Thermodyna mik der Schmelze, der Fluiddynamik und Transportphänomenen über die Kinetik der Erstarrung, mit eingeschlossen auch Seigerungsvorgänge sowie die damit verbundenen Wachstumsfrontmor phologien, bis hin zu Vorgängen im Festkörper, insbesondere ausgelöst durch Grenzflächen (Ost waldreifung, Korngrenzendynamik), wurde vieles verknüpft, was nicht oft in einem Atemzug ge nannt wird. Auch technologische Fragestellungen wurden nicht ausgelassen, wie beispielsweise die Prozesse in der Gießereitechnik. 420 pp. Deutsch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Control of Flexible-link Manipulators Using Neural Networks addresses the difficulties that arise in controlling the end-point of a manipulator that has a significant amount of structural flexibility in its links. The non-minimum phase characteristic, coupling effects, nonlinearities, parameter variations and unmodeled dynamics in such a manipulator all contribute to these difficulties. Control strategies that ignore these uncertainties and nonlinearities generally fail to provide satisfactory closed-loop performance. This monograph develops and experimentally evaluates several intelligent (neural network based) control techniques to address the problem of controlling the end-point of flexible-link manipulators in the presence of all the aforementioned difficulties. To highlight the main issues, a very flexible-link manipulator whose hub exhibits a considerable amount of friction is considered for the experimental work. Four different neural network schemes are proposed and implemented on the experimental test-bed. The neural networks are trained and employed as online controllers. 168 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Historical interest and studies of Weyl's role in the interplay between 20th-century mathematics, physics and philosophy have been increasing since the middle 1980s, triggered by different activities at the occasion of the centenary of his birth in 1985, and are far from being exhausted. The present book takes Weyl's 'Raum - Zeit - Materie' (Space - Time -Matter) as center of concentration and starting field for a broader look at his work. The contributions in the first part of this volume discuss Weyl's deep involvement in relativity, cosmology and matter theories between the classical unified field theories and quantum physics from the perspective of a creative mind struggling against theories of nature restricted by the view of classical determinism. In the second part of this volume, a broad and detailed introduction is given to Weyl's work in the mathematical sciences in general and in philosophy. It covers the whole range of Weyl's mathematical and physical interests: real analysis, complex function theory and Riemann surfaces, elementary ergodic theory, foundations of mathematics, differential geometry, general relativity, Lie groups, quantum mechanics, and number theory. 403 pp. Deutsch, Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book the author considers data from both early and later schools of Buddhism in an attempt to provide an overall characterization of the structure of Buddhist ethics. The importance of ethics in the Buddha's teachings is widely acknowledged, but the pursuit of ethical ideals has up to now been widely held to be secondary to the attainment of knowledge. Drawing on the Aristotelian tradition of ethics the author argues against this intellectualization of Buddhism and in favour of a new understanding of the tradition in terms of which ethics plays an absolutely central role. In the course of this reassessment many basic concepts such as karma, nirvana, and the Eightfold Path, are reviewed and presented in a fresh light. The book will be of interest to readers with a background in either Buddhist studies or comparative religious ethics. 269 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Go to, let us go down, and there confound their language, that they may not understand one another's speech. So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to built the city. (Genesis 11.7-8) 1.1 Static Focal Points 1.1.1 Coordination In real life, people quite often face situations in which they prefer to act in the same way, but they are not particular about the concrete way of acting. Some examples are given below: Credit cards: Buyers want to possess the credit cards potential sellers do accept. Also, sellers wish to have contracted the credit card company the credit cards of which potential customers usually carry along. For both, basically, it is all the same which credit card this is. What matters is that both choices coincide. Communication, information transmission: The transmission of in formation requires that the signals used have the same meaning to both the sender and the receiver. But it is inessential which signal has a certain mean ing. In verbal communication, this basically means that the people involved use the same (natural) language, though even then some ambiguities remain. Things are a bit more difficult for non-verbal communication, for example data transmission between computers-both sides have to use the same or compatible protocols. Again, what matters is the protocols to be the same for both sides. 152 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now no longer necessary to argue the importance of agent technology. Be- des numerous conferences and workshops on speci c aspects of agent technology there are also many companies that are exploring its exploitation possibilities. In the light of these developments and in order to foster the transfer of agent technology from research labs to business, the EU has funded a network of exc- lence' devoted to agent technology. This network of excellence, called AgentLink , aims at bringing together research groups from d- ferent countries and industrial developers. The ultimate goal is to create synergy among the di erent projects and groups to improve the competence of European industry and the excellence of academia. In order to achieve this goal, Agent- Link organises educational activities (summer schools), builds agent-related - terature repositories, and facilitates collaboration between member nodes. One of the main activities related to the last point are the regular meetings of S- cial Interest Groups' (SIGs). At this moment six SIGs are functioning, focusing on topics ranging from agent based social simulation to intelligent agents for telecommunications applications and telematics. The current book combines two results from the activities of the SIG on Agent Mediated Electronic Commerce'. This SIG gathers the main research groups and industrial partners interested in the use of agent technology in el- tronic commerce. First and foremost the book contains a roadmap of research and current technological developments in the area of agent-mediated electronic commerce. 252 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The wait for the year 2000 was marked by the fear of possible bugs that might have arisen at its beginning. One additional fear we had during this wait was whether - ganising this event would have generated a boon or another bug. The reasons for this fear originated in the awareness that the design of interactive systems is a fast moving area. The type of research work presented at this unique event has received limited support from funding agencies and industries making it more difficult to keep up with the rapid technological changes occurring in interaction technology. However, despite our fear, the workshop was successful because of the high-quality level of participation and discussion. Before discussing such results, let us step back and look at the evolution of DSV-IS (Design, Specification and Verification of Interactive Systems), an international wo- shop that has been organised every year since 1994. The first books that addressed this issue in a complete and thorough manner were the collection of contributions edited by Harrison and Thimbleby and the book written by Alan Dix, which focused on abstractions useful to highlight important concepts in the design of interactive systems. Since then, this area has attracted the interest of a wider number of research groups, and some workshops on related topics started to be organised. DSV-IS had its origins in this spreading and growing interest. The first workshop was held in a monastery located in the hills above Bocca di Magra (Italy). 268 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These post-proceedings contain the revised versions of the papers presented at the Symposium on Objects and Databases' which was held in Sophia-Antipolis, France, June 13, 2000, in conjunction with the Fourteenth European Conference on Object-Oriented Programming, ECOOP 2000. This event continued the t- dition established the year before in Lisbon (Portugal) with the First Workshop on Object-Oriented Databases. The goal of the symposium was to bring together researchers working in various corners of the eld of objects and databases, to discuss the current state of research in the eld and to critically evaluate existing solutions in terms of their current usage, their successes and limitations, and their potential for new applications. The organizing committee received 21 papers which were reviewed by a p- gram committee of people active in the eld of objects and databases. There were 3 reviews for each paper, and nally the organizing committee selected 9 long papers, 2 short papers, and a demonstration to be presented and discussed at the symposium. The selected papers cover a wide spectrum of topics, including data modeling concepts, persistent object languages, consistency and integrity of persistent data, storage structures, class versioning and schema evolution, query languages, and temporal object-oriented databases. In addition to the regular papers, the symposium included an invited p- sentation, given by Prof. Malcolm Atkinson from the University of Glasgow (Scotland) where he heads the Persistence and Distribution Group. 216 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -New object-oriented technologies have been conceived and implemented over the past decade in order to manage complexity inherent in information systems development. Research has spanned from information systems modelling languages (UML and OML) to databases (ODMG), from programming languages (Java) to middleware technology (CORBA). A more widespread use of the Internet has led to the emergence and integration of various other technologies, such as XML and database connectivity tools, allowing businesses to access and exchange information over the Internet. The main theme of OOIS 2000 was 'Object-Technology and New Business Opportunities' and focused on research conducted in the area of effective information systems development for the promotion of e-commerce. Papers were invited from academics and practitioners. The thirty-nine papers accepted for oms 2000 are included in these proceedings. It is nice to see this year that the shift from centralised to distributed systems and the widespread access and use of the Internet has allowed the advent of new opportunities for businesses to exploit, in the form of e-commerce. 480 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is based on papers accepted for the Second International Workshop on Multi-agent-based Simulation (MABS-2000)federated with the Fourth Int- national Conference on Multi Agent Systems (ICMAS-2000)held in Boston in July 2000. The purpose of MABS-2000 was to investigate and develop the synergy - tween software engineering for multi-agent systems and agent-based social s- ulation. The papers included in the MABS-2000 workshop were selected either because they explore how agent interaction can be used to build multi-agent s- tems or they o er examples of problem-oriented (rather than technique-oriented) systems. No paper was selected if it speci ed a model or an issue to make it t a previously chosen technique. All of the papers in the volume have been reviewed and in many cases revised since the workshop. Two papers (by Edmonds and by Hales)as well as the editorial introduction have been added to those accepted for the workshop. As editors and workshop organisers, we are very grateful to the participants who engaged enthusiastically in the discussions about both individual papers and the issues facing the MABS community. Issues raised and positions taken in those discussions are reported in the editorial introduction. We are also grateful to the authors for their punctuality and the grace with which they received and responded to editorial comments and requests. Klaus Fischer, the ICMAS-2000 workshops chair, was exceptionally patient and diplomatic in reconciling our demands with the resources available. 280 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the most important reasons for the current intensity of interest in agent technology is that the concept of an agent, as an autonomous system capable of interacting with other agents in order to satisfy its design objectives, is a natural one for software designers. Just as we can understand many systems as being composed of essentially passive objects, which have a state and upon which we can perform operations, so we can understand many others as being made up of interacting semi-autonomous agents. This book brings together revised versions of papers presented at the First International Workshop on Agent-Oriented Software Engineering, AOSE 2000, held in Limerick, Ireland, in conjunction with ICSE 2000, and several invited papers. As a comprehensive and competent overview of agent-oriented software engineering, the book addresses software engineers interested in the new paradigm and technology as well as research and development professionals active in agent technology. 340 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Arguably, many industrial optimization problems are of the multiobjective type. The present work, after providing a survey of the state of the art in multiobjective optimization, gives new insight into this important mathematical field by consequently taking up the viewpoint of differential geometry. This approach, unprecedented in the literature, very naturally results in a generalized homotopy method for multiobjective optimization which is theoretically well-founded and numerically efficient. The power of the new method is demonstrated by solving two real-life problems of industrial optimization.The book presents recent results obtained by the author and is aimed at mathematicians, scientists, students and practitioners interested in optimization and numerical homotopy methods. 135 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an extended version of the notes of my lecture course given at ETH in spring 1999. The course was intended as an introduction to combinatorial torsions and their relations to the famous Seiberg-Witten invariants. Torsions were introduced originally in the 3-dimensional setting by K. Rei demeister (1935) who used them to give a homeomorphism classification of 3-dimensional lens spaces. The Reidemeister torsions are defined using simple linear algebra and standard notions of combinatorial topology: triangulations (or, more generally, CW-decompositions), coverings, cellular chain complexes, etc. The Reidemeister torsions were generalized to arbitrary dimensions by W. Franz (1935) and later studied by many authors. In 1962, J. Milnor observed 3 that the classical Alexander polynomial of a link in the 3-sphere 8 can be interpreted as a torsion of the link exterior. Milnor's arguments work for an arbitrary compact 3-manifold M whose boundary is non-void and consists of tori: The Alexander polynomial of M and the Milnor torsion of M essentially coincide. 124 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Self-adaptive software evaluates its own behavior and changes its behavior when the evaluation indicates that the software does not accomplish what it is intended to do or when better functionality or better performance is possible. The self-adaptive approach in software engineering builds on well-known features like the use of errors and the handling of exceptions in languages like Lisp or Java and aims at improving the robustness of software systems by gradually adding new features of self-adaption and autonomity.This book originates from the First International Workshop on Self-Adaptive Software, IWSAS 2000, held in Oxford, UK in April 2000. The revised full papers presented in the volume together with an introductory survey by the volume editors assess the state of the art in this emerging new field and set the scene for future research and development work. 264 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the characteristics of modern algebra is the development of new tools and concepts for exploring classes of algebraic systems, whereas the research on individual algebraic systems (e. g. , groups, rings, Lie algebras, etc. ) continues along traditional lines. The early work on classes of alge bras was concerned with showing that one class X of algebraic systems is actually contained in another class F. Modern research into the theory of classes was initiated in the 1930's by Birkhoff's work [1] on general varieties of algebras, and Neumann's work [1] on varieties of groups. A. I. Mal'cev made fundamental contributions to this modern development. ln his re ports [1, 3] of 1963 and 1966 to The Fourth All-Union Mathematics Con ference and to another international mathematics congress, striking the ories of classes of algebraic systems were presented. These were later included in his book [5]. International interest in the theory of formations of finite groups was aroused, and rapidly heated up, during this time, thanks to the work of Gaschiitz [8] in 1963, and the work of Carter and Hawkes [1] in 1967. The major topics considered were saturated formations, Fitting classes, and Schunck classes. A class of groups is called a formation if it is closed with respect to homomorphic images and subdirect products. A formation is called saturated provided that G E F whenever Gjip(G) E F. 276 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Enzymes in Action is a timely survey of a modern development in organic chemistry. It is clear that bioreagents demand that organic chemists think in a different way. If they do so, they will open up new avenues of exciting, new chemistry that will permit problems to be solved in an elegant way. The first section covers the concepts necessary to understand enzymes in molecular operations. The second section covers heteroatom enzyme chemistry, with considerable attention being given to the use of enzymes in the detoxification of chemical warfare agents and their application in environmental problems. The final section highlights the strategic use of enzymes in organic chemistry. It is clear that the term `green chemistry' is appropriate, since enzyme mediated processes occur under mild, environmentally benign conditions, and enzymes enable chemists to perform new chemical operations that would otherwise be difficult to achieve at all. 472 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This year's meeting marked the Eighth International Symposium on Graph D- wing. The organizing and program committees worked hard to make this year's symposium possible, and we were delighted that so many people came to - lonial Williamsburg, Virginia, for three days of the latest results in the eld of graph drawing. As in previous years, the review process was quite competitive. We accepted 30 out of 53 regular-length submissions, and 5 out of 15 short submissions, for a total acceptance ratio of 35 out of 68, or 51%. This year's program featured several new developments in the eld. Four di erent approaches for handling very large graphs were presented in a session on force-directed layout. Two sessions were devoted to the latest advances in orthogonal graph drawing. And alongside the usual mix of theory and practice papers we had several contributions based on empirical studies of users and of systems. Our invited talks were given by two speakers who were new to most members of the GD community, but who work in areas that are closely related to graph drawing. Professor Colin Ware of the University of New Hampshire told us how knowledge of human visual perception is useful for the design of e ective data visualizations. And Professor David Jensen of the University of Massachusetts at Amherst talked about the process of knowledge discovery from graphs, a process that involves more than just graph drawing and visualization. 436 pp. Englisch.…
