Taschenbuch. Condizione: Neu. Neuware -In the ten years since the first MAAMAW was held in 1989, at King's College, Cambridge, the field of Multi-Agent Systems (MAS) has flourished. It has attracted an increasing amount of theoretical and applied research. During this decade, important efforts have been made to establish the scientific and technical foundations of MAS. MAAMAW publications are testimony to the progress achieved in key areas such as agent modelling and reasoning, multi-agent interaction and communication, and multi-agent organisation and social structure. Research results have covered a wide range of inter-related topics in each area including agent architectures, reasoning models, logics, conflict resolution, negotiation, resource allocation, load balancing, learning; social behaviour and interaction, languages and protocols, interagent and agent-human communication, social models, agent roles, norms and social laws, and static and dynamic organisational structures. The feasibility and the viability of the proposed models and techniques have been demonstrated through MAS applications in heterogeneous domains including electronic commerce, co-operative work, telecommunications, social and biological systems, robotics, office and business automation, public administration, social simulations and banking. As the applicability of the technology became understood, the multi-agent paradigm has been progressively accepted by product managers and system developers, giving rise to a considerable amount of business expectation from industry. These expectations do not rest on the concept or metaphor of agent, but on the development of MAS useful in an industrial setting, with real-time systems presenting the biggest challenge.

Taschenbuch. Condizione: Neu. Neuware -This monograph deals with two aspects of the theory of elliptic genus: its topological aspect involving elliptic functions, and its representation theoretic aspect involving vertex operator super-algebras. For the second aspect, elliptic genera are shown to have the structure of modules over certain vertex operator super-algebras. The vertex operators corresponding to parallel tensor fields on closed Riemannian Spin Kähler manifolds such as Riemannian tensors and Kähler forms are shown to give rise to Virasoro algebras and affine Lie algebras. This monograph is chiefly intended for topologists and it includes accounts on topics outside of topology such as vertex operator algebras.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 404 pp. Englisch.

Buch. Condizione: Neu. Neuware -The Eighth EPSRC Numerical Analysis Summer School was held at the Uni versity of Leicester from the 5th to the 17th of July, 1998. This was the third Numerical Analysis Summer School to be held in Leicester. The previous meetings, in 1992 and 1994, had been carefully structured to ensure that each week had a coherent 'theme'. For the 1998 meeting, in order to widen the audience, we decided to relax this constraint. Speakers were chosen to cover what may appear, at first sight, to be quite diverse areas of numeri cal analysis. However, we were pleased with the extent to which the ideas cohered, and particularly enjoyed the discussions which arose from differing interpretations of those ideas. We would like to thank all six of our main speakers for the care which they took in the preparation and delivery of their lectures. In this volume we present their lecture notes in alphabetical rather than chronological order. Nick Higham, Alastair Spence and Nick Trefethen were the speakers in week 1, while Bernardo Cockburn, Stig Larsson and Bob Skeel were the speakers in week 2. Another new feature of this meeting compared to its predecessors was that we had 'invited seminars'. A numer of established academics based in the UK were asked to participate in the afternoon seminar program. 268 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Image-based rendering, as an area of overlap between computer graphics and computer vision, uses computer vision techniques to aid in sythesizing new views of scenes. Image-based rendering methods are having a substantial impact on the field of computer graphics, and also play an important role in the related field of multimedia systems, for applications such as teleconferencing, remote instruction and surgery, virtual reality and entertainment.The book develops a novel way of formalizing the view synthesis problem under the full perspective model, yielding a clean, linear warping equation. It shows new techniques for dealing with visibility issues such as partial occlusion and 'holes'. Furthermore, the author thoroughly re-evaluates the requirements that view synthesis places on stereo algorithms and introduces two novel stereo algorithms specifically tailored to the application of view synthesis.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 188 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Today's microprocessors are the powerful descendants of the von Neumann 1 computer dating back to a memo of Burks, Goldstine, and von Neumann of 1946. The so-called von Neumann architecture is characterized by a se quential control flow resulting in a sequential instruction stream. A program counter addresses the next instruction if the preceding instruction is not a control instruction such as, e. g. , jump, branch, subprogram call or return. An instruction is coded in an instruction format of fixed or variable length, where the opcode is followed by one or more operands that can be data, addresses of data, or the address of an instruction in the case of a control instruction. The opcode defines the types of operands. Code and data are stored in a common storage that is linear, addressed in units of memory words (bytes, words, etc. ). The overwhelming design criterion of the von Neumann computer was the minimization of hardware and especially of storage. The most simple implementation of a von Neumann computer is characterized by a microar chitecture that defines a closely coupled control and arithmetic logic unit (ALU), a storage unit, and an I/O unit, all connected by a single connection unit. The instruction fetch by the control unit alternates with operand fetches and result stores for the AL U.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book treats modern aspects of open systems, measurement, and decoherence in relativistic quantum theory. It starts with a comprehensive introduction to the problems related to measuring local and nonlocal observables and the constraints imposed by the causality principle. In the articles that follow, the emphasis lies on new theoretical models. Quantum dynamical semigroups and stochastic processes in Hilbert space are introduced, as are dynamical reduction models. Further topics include relativistic generalizations of the continuous spontaneous localization model and of the quantum state diffusion model and decoherence and the dynamical selection of preferred basis sets in the framework of continuous measurement theory and of the decoherent histories approach. Mathematical aspects of quantum measurement theory and dynamical entropies are also studied from the viewpoint of the operational approach to quantum mechanics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book offers the first comprehensive account of the new method of density matrix renormalization. Recent years have seen enormous progress in the numerical treatment of low-dimensional quantum sytems. With this new technique, which selects a reduced set of basis states via density matrices, it has become possible to treat large systems with amazing accuracy. The method has been applied successfully to a variety of important one-dimensional problems such as spin chains, Kondo models, and correlated electron systems. Extensions to other systems and higher dimensions are currently being developed. The contributions to this book are written by leading experts in the field. The two parts contain an introduction to the subject and a review of physical applications. As a combination of advanced textbook and guide to current research the book should become a standard source for everyone interested in the topic.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Buch. Condizione: Neu. Neuware -Nuclear Oncology describes the use of radionuclides in the diagnosis and management of malignant tumors. Both in vivo and in vitro techniques are included. The book was written by an international panel of authors, most, if not all, of whom are the pioneers of the techniques described. Their chapters reflect the universal views in the field of nuclear medicine and oncology. Clinical aspects and technical details are presented for both standard and new nuclear oncological techniques, including breast scintigraphy, receptor imaging, monoclonal antibodies and positron emission tomography. This information will therefore be helpful to those dealing with the diagnosis and therapy of cancer using radionuclides, including medical oncologists, radiation oncologists, oncologic surgeons, nuclear medicine physicians and radiologists. Attention is devoted to potential areas of clinical research in nuclear oncology. Therapeutic use of radionuclides is emphasized.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 476 pp. Englisch.

Buch. Condizione: Neu. Neuware -Development in science depends on several factors. Among these, the role of individual scientists is perhaps not the most important one. Science is typically a body of collective knowledge and any increase in the amount of this knowledge is certainly due to strong interaction among scientists. Even in the past, it happened quite rarely that a single person, without any aid of others, d- covered something fundamental or opened a new chapter in science. Great figures of science history have, in most cases, had rather a summarizing and s- thesizing role. This is especially valid over the last few decades. On one hand, the amount of information necessary to achieve new discoveries, has increased tremendously. On the other hand, improvement of technical facilities has increased the speed of information exchange. These factors resulted in a degree of specialization in science that had never seen before. Most of us are experts and specialists rather than scientists in the classical sense. My personal feeling is that, even nowadays, there is a strong need for professionals with a broad knowledge and c- prehensive mind, although they may not be competitive in the number of their publications or the sizes of their grants. Every time I have met such a person (I can count these cases on my fingers) I have become deeply influenced by his or her strong intellect.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condizione: Neu. Neuware -In important branches of manufacturing industries, especially those producing chemicals, polymers, semiconductors, ceramics, metals and alloys, analytical process control is already an integral part of the company. Far reaching decisions with respect to quality, ecology and economy are based on the respective analytical data. The goal of this practice-oriented book is to introduce chemists, engineers and technicians to the strategies, techniques and efficiency of modern process analytical chemistry. The author is especially aiming at those professionals in small and medium enterprises who have to carry out process control tasks in a 'solo-run'. 256 pp. Englisch.

Buch. Condizione: Neu. Neuware -Inorganic polyphosphates - polymers of orthophosphate linked by high-energy phosphoanhydride bonds - have been found in apparently all forms of life, from bacteria, yeasts and fungi to higher plants and animals. These polymers, which had been neglected for a long time, have become a fascinating area of research in the last few years. This volume summarizes the present state of knowledge about the metabolism and function of inorganic polyphosphates. In addition, the methods to study these polymers as well as the biotechnological applications of inorganic polyphosphates are described. The 15 chapters of this volume, dealing with different aspects of polyphosphate research, are written by experts in the field. This book represents a valuable source of information not only for researchers working on this subject, but also for scientists interested in fundamental aspects of cell and energy metabolism. 336 pp. Englisch.

Buch. Condizione: Neu. Neuware -Zeolites occur in nature and have been known for almost 250 years as alumino silicate minerals. Examples are clinoptilolite, mordenite, offretite, ferrierite, erionite and chabazite. Today, most of these and many other zeolites are of great interest in heterogeneous catalysis, yet their naturally occurring forms are of limited value as catalysts because nature has not optimized their properties for catalytic applications and the naturally occurring zeolites almost always contain undesired impurity phases. It was only with the advent of synthetic zeolites in the period from about 1948 to 1959 (thanks to the pioneering work of R. M. Barrer and R. M. Milton) that this class of porous materials began to playa role in catalysis. A landmark event was the introduction of synthetic faujasites (zeolite X at first, zeolite Y slightly later) as catalysts in fluid catalytic cracking (FCC) of heavy petroleum distillates in 1962, one of the most important chemical processes with a worldwide capacity of the order of 500 million t/a. Compared to the previously used amorphous silica-alumina catalysts, the zeolites were not only orders of magnitude more active, which enabled drastic process engineering improvements to be made, but they also brought about a significant increase in the yield of the target product, viz. motor gasoline. With the huge FCC capacity worldwide, the added value of this yield enhancement is of the order of 10 billion US $ per year.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 588 pp. Englisch.

Buch. Condizione: Neu. Neuware -This monograph has been written for clinicians who are involved in the management of the dizzy patient and for scientists with a particular interest in the multi-sensorimotor mechan isms that subserve spatial orientation, motion perception, and ocular motor and postural con trol. Special emphasis has been put on making the correct diagnosis, and detailed recommendations have been given for specific treatments. The second edition has resulted in an almost completely new book due to the dramatic expansion in the 1990s of our understanding of vestibular function and disorders. A few rele vant examples include the novel concept of canalolithiasis, as opposed to cupulolithiasis, both of which are established causes of typical posterior and horizontal canal benign paroxysmal positioning vertigo; familial episodic ataxia I and II have been identified as inherited chan nelopathies; otolithic syndromes were recognized as a variety separate from semicircular canal syndromes; several new central vestibular syndromes have been described, localized, and attributed to vestibular pathways and centres; a new classification based on the three major planes of action of the vestibulo-ocular reflex is available for central vestibular syn dromes; and the mystery of the location and function of the multisensory vestibular cortex is slowly being unravelled. This book differs from other clinical textbooks in that it is not divided into two parts: anatomy and physiology, on the one hand, and disorders, on the other. 532 pp. Englisch.

Buch. Condizione: Neu. Neuware -Mediziner und Marketing: Mode oder Mehr Widerspruch oder Ansporn zum Aufbruch Die vorliegende Studie, die mit dem 1. Wissenschaftspreis der Gesell schaft fur Recht und Politik im Gesundheitswesen (GRPG) ausgezeichnet wurde, ist ein Beitrag zu der Frage, wo die Grenze verlauft zwischen gewiinschter Pati enteninformation und unerwiinschten Effekten von 'Werbung'. Sie will den Rah men abstecken, in dem sich eine moderne arztliche Kornrnunikation mit Patien ten bewegen mufi, weniger aus der herkornrnlichen Arztperspektive als vielmehr aus der bislang weitgehend vernachlassigten Patientenperspektive. Die Studie versteht sieh als ein kritischer Diskussionsbeitrag, der zum Nachdenken, Uber denken und Weiterdenken anregen will. Sie wendet sich vor allem an den arztli chen Selbst-Gestaltungs-Gesetzgeber und damit letztlich an jeden einzelnen Arzt. Die hier gemachten, an Patientengrundrechten orientierten Vorschliige gehen weit tiber das hinaus, was derzeitig nur ansatzweise in der deutschen Arzteschaft diskutiert wird. Bis Herbst 1998 erschienenes Material konnte Berucksichtigung finden. 1m engsten Farnilienkreis habe ieh die Erfahrung gemacht, daB es engagierte Arzte gibt, die in ihrem Beruf noch eine Berufung sehen. Sie setzen sich vorbild lich fur ihre Patienten ein, die sie durch ihre fachliche wie menschliche Kompe tenz irnrner wieder begeistern. Es gibt aber leider viel zu viele Arzte, fur die sich eine solche Aussage nieht treffen liillt, die anderen Leitsternen folgen als dem Patienteninteresse. Die Besseren von den Guten fur den Patienten unterscheidbar zu machen, ist das Hauptanliegen dieser Arbeit. Sie will aber auch die Guten durch 'sanften' Transparenzdruck errnuntern, schon bald zu den Besseren zu ge hOren.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 620 pp. Deutsch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The book is about differentiability of six operators on functions or pairs of functions: composition (f of g), integration (of f dg), multiplication and convolution of two functions, both varying, and the product integral and inverse operators for one function. The operators are differentiable with respect to p-variation norms with optimal remainder bounds. Thus the functions as arguments of the operators can be nonsmooth, possibly discontinuous, but four of the six operators turn out to be analytic (holomorphic) for some p-variation norms. The reader will need to know basic real analysis, including Riemann and Lebesgue integration. The book is intended for analysts, statisticians and probabilists. Analysts and statisticians have each studied the differentiability of some of the operators from different viewpoints, and this volume seeks to unify and expand their results. 292 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume opens a new frontier for clinical specialists dealing with vertigo sufferers. As our populations are constantly growing older, we have to deal more and more with degenerative neurosensorial disor ders of elderly persons not only from the investigative, but also from the innovative therapeutic point of view. This book's theme of vertigo and dizziness rehabilitation has been chosen in the sense of applied neurootometry and conservative neu roototherapy. The authors describe a new way of utilizing objective and quantitative neurosensorial equilibrium function measurements for special reprogramming and retraining purposes. In the field of diagnosis they place functional investigation of the equilibrium sys tem alongside the other classical techniques which mostly work through inspection and imaging. Consequently, the MCS method of treatment (mechanics, cybernetics, synergetics) has to take into ac count the basic knowledge on information transfer from the inner ear hair cells to the central nervous system in the regulating centers of the brainstem. 256 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The 1999 international conference on Information Processing in Medical Imaging (IPMI '99) was the sixteenth in the series of biennial meetings and followed the successful meeting in Poultney, Vermont, in 1997. This year, for the rst time, the conference was held in central Europe, in the historical Hungarian town of Visegr ad, one of the most beautiful spots not only on the Danube Bend but in all Hungary. The place has many historical connections, both national and international. The castle was once a royal palace of King Matthias. In the middle ages, the Hungarian, Czech, and Polish kings met here. Recently, after the summit meeting of reestablished democracies in the area, it became a symbol for the cooperation between central European countries as they approached the European Union. It was thus also symbolic to bring IPMI, in the year of the 30th anniversary of its foundation, to this place, and organize the meeting with the close cooperation of local and traditional western organizers. It also provided a good opportunity to summarize brie y a history of IPMI for those who were new to the IPMI conference. This year we received 82 full paper submissions from all over the world. Of these, 24 were accepted as oral presentations. These were divided into 6 sessions. In spite of our e orts, it was found to be impossible to make these sessions fully balanced and homogeneous. 532 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -With all of the news about the Internet and the Y2K problem, it is easy to forget that other areas of computer science still exist. Reading the newspaper or watching the television conveys a very warped view of what is happening in computer science. This conference illustrates how a maturing subdiscipline of computer science can continue to grow and integrate within it both old and new approaches despite (or perhaps due to) a lack of public awareness. The conceptual graph community has basically existed since the 1984 publication of John Sowa's book, 'Conceptual Structures: Information Processing In Mind and Machine.' In this book, John Sowa laid the foundations for a knowledge representation model called conceptual graphs based on semantic networks and the existential graphs of C.S. Peirce. Conceptual graphs constitutes a very powerful and expressive knowledge representation scheme, inheriting the benefits of logic and the mathematics of graphs. The expressiveness and formal underpinnings of conceptual graph theory have attracted a large international community of researchers and scholars. The International Conferences on Conceptual Structures, and this is the seventh in the series, is the primary forum for these researchers to report their progress and activities. As in the past, the doors were open to admit alternate representation models and approaches. 536 pp. Englisch.
