Taschenbuch. Condizione: Neu. Neuware -Domain decomposition methods are a well established tool for an efficient numerical solution of partial differential equations, in particular for the coupling of different model equations and of different discretization methods. Based on the approximate solution of local boundary value problems either by finite or boundary element methods, the global problem is reduced to an operator equation on the skeleton of the domain decomposition. Different variational formulations then lead to hybrid domain decomposition methods.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 132 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Two basic problems of representation theory are to classify irreducible representations and decompose representations occuring naturally in some other context. Algebras of Iwahori-Hecke type are one of the tools and were, probably, first considered in the context of representation theory of finite groups of Lie type. This volume consists of notes of the courses on Iwahori-Hecke algebras and their representation theory, given during the CIME summer school which took place in 1999 in Martina Franca, Italy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 128 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -During the last decade enormous progress has been achieved in the field of computational fluid dynamics. This became possible by the development of robust and high-order accurate numerical algorithms as well as the construc tion of enhanced computer hardware, e. g. , parallel and vector architectures, workstation clusters. All these improvements allow the numerical simulation of real world problems arising for instance in automotive and aviation indus try. Nowadays numerical simulations may be considered as an indispensable tool in the design of engineering devices complementing or avoiding expen sive experiments. In order to obtain qualitatively as well as quantitatively reliable results the complexity of the applications continuously increases due to the demand of resolving more details of the real world configuration as well as taking better physical models into account, e. g. , turbulence, real gas or aeroelasticity. Although the speed and memory of computer hardware are currently doubled approximately every 18 months according to Moore's law, this will not be sufficient to cope with the increasing complexity required by uniform discretizations. The future task will be to optimize the utilization of the available re sources. Therefore new numerical algorithms have to be developed with a computational complexity that can be termed nearly optimal in the sense that storage and computational expense remain proportional to the 'inher ent complexity' (a term that will be made clearer later) problem. This leads to adaptive concepts which correspond in a natural way to unstructured grids.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The workshop on an Infrastructure for Mobile and Wireless Systems was held in Scottsdale, Arizona on October 15, 2001 and was funded by the National Science Foundation (NSF) and sponsored by the Telecommunications and Information Technology Institute of the College of Engineering at Florida International U- versity (FIU), to establish a common infrastructure for the discipline of mobile and wireless networking, and to serve its rapidly emerging mobile and wireless community of researchers and practitioners. The workshop provides a single, cohesive, and high-quality forum for disseminating research and experience in this emerging eld. Of signi cance is the integration of many diverse com- nities. The areas of mobile and wireless networking combine the best of both worlds, namely academia and industry. The objective of the workshop is to - ne and establish a common infrastructure of the discipline and to develop a consensus-based document that will provide a foundation for implementation, standardization, and further research. Workshop Program Chairs Dr. Birgitta K¿ onig-Ries (Universit¿at Karlsruhe), and Dr. Peter Scheuermann (Northwestern University) and Vice Program Chair Dr. S. A. M. Makki (Queensland University of Technology), assembled a truly - pressive program committee. Together with the program committee, they worked diligently to select papers and speakers that met the criteria of high quality and relevance to our various elds of interest. It takes time and e ort to review a - per carefully, and every member of the program committee is to be commended for his/her contribution to the success of this workshop. 200 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book examines the allocational and distributional impacts of international climate policy on different regions of the world by taking into account the ongoing process of globalization. It concentrates on the impacts of trade in goods and international capital mobility on climate policy outcomes. The costs of an international climate policy are assessed by incorporating the Kyoto Protocol into a multi-regional, multi-sectoral, recursive dynamic trade model based on empirical data. Climate policy leads to a change in relative competitiveness between sectors and regions, thus inducing output shifts, international capital flows, welfare changes and carbon leakage. Welfare costs can be reduced by a higher integration into the world market and a diversification of the export structure.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 328 pp. Englisch.

Buch. Condizione: Neu. Neuware -In mammals, a robust physiologic system acts to maintain relative constancy of weight. A key element of this system is leptin. The nature of this 'brain-somatic' cross talk is as yet poorly understood, but it is likely to have important implications for the pathophysiology and treatment of obesity, diabetes and other metabolic disorders.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Buch. Condizione: Neu. Neuware -The eld of robotics continues to ourish and develop. In common with general scienti c investigation, new ideas and implementations emerge quite spontaneously and these are discussed, used, discarded or subsumed at c- ferences, in the reference journals, as well as through the Internet. After a little more maturity has been acquired by the new concepts, then archival publication as a scienti c or engineering monograph may occur. The goal of the Springer Tracts in Advanced Robotics is to publish new developments and advances in the elds of robotics research ¿ rapidly and informally but with a high quality. It is hoped that prospective authors will welcome the opportunity to publish a structured presentation of some of the emerging robotics methodologies and technologies. The edited volume by Antonio Bicchi, Henrik Christensen and Domenico Prattichizzo is the outcome of the second edition of a workshop jointly sponsored by the IEEE Control Systems Society and the IEEE Robotics and Automation Society. Noticeably, the previous volume was published in the Springer Lecture Notes on Control and Information Sciences. The authors are recognised as leading scholars internationally. A n- ber of challenging control problems on the forefront of today¿s research in robotics and automation are covered, with special emphasis on vision, sensory-feedback control, human-centered robotics, manipulation, planning, exible and cooperative robots, assembly systems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Condizione: Neu. Neuware -Properties of systems with long range interactions are still poorly understood despite being of importance in most areas of physics. The present volume introduces and reviews the effort of constructing a coherent thermodynamic treatment of such systems by combining tools from statistical mechanics with concepts and methods from dynamical systems. Analogies and differences between various systems are examined by considering a large range of applications, with emphasis on Bose--Einstein condensates. Written as a set of tutorial reviews, the book will be useful for both the experienced researcher as well as the nonexpert scientist or postgraduate student.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -On behalf of the PROFES organizing committee we would like to welcome you to the 4th International Conference on Product Focused Software Process Impro- ment (PROFES 2002) in Rovaniemi, Finland. The conference was held on the Arctic Circle in exotic Lapland under the Northern Lights just before Christmas time, when Kaamos (the polar night is known in Finnish as ¿Kaamos¿) shows its best characteristics. PROFES has established itself as one of the recognized international process improvement conferences. Despite the current economic downturn, PROFES has attracted a record number of submissions. A total of 70 full papers were subm- ted and the program committee had a di cult task in selecting the best papers to be presented at the conference. The main theme of PROFES is professional software process improvement (SPI) motivated by product and service quality needs. SPI is facilitated by so- ware process assessment, software measurement, process modeling, and techn- ogy transfer. It has become a practical tool for quality software engineering and management. The conference addresses both the solutions found in practice and the relevant research results from academia. 668 pp. Englisch.

Buch. Condizione: Neu. Neuware -The behaviour of many complex materials extends over time- and lengthscales well beyond those that can normally be described using standard molecular dynamics or Monte Carlo simulation techniques. As progress is coming more through refined simulation methods than from increased computer power, this volume is intended as both an introduction and a review of all relevant modern methods that will shape molecular simulation in the forthcoming decade. Written as a set of tutorial reviews, the book will be of use to specialists and nonspecialists alike.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 532 pp. Englisch.

Buch. Condizione: Neu. Neuware -Ruthenate materials have come into focus recently because of their very interesting magnetic and superconducting properties. From the first international conference on this topic, the present volume has emerged as a first coherent account of the considerable body of work, both theoretical and experimental, gathered in this field within a short time span. The book has been written in the form of a set of lectures and tutorial reviews with the aim of providing the research community with both a comprehensive and modern source of reference and a tutorial introduction for postgraduate students and nonspecialists working in related areas.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 360 pp. Englisch.

Buch. Condizione: Neu. Neuware -Causal relations, and with them the underlying null cone or conformal structure, form a basic ingredient in all general analytical studies of asymptotically flat space-time. The present book reviews these aspects from the analytical, geometrical and numerical points of view. Care has been taken to present the material in a way that will also be accessible to postgraduate students and nonspecialist reseachers from related fields.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 392 pp. Englisch.

Buch. Condizione: Neu. Neuware -In the last two decades extraordinary progress in the experimental handling of single quantum objects has spurred theoretical research into investigating the coupling between quantum systems and their environment. Decoherence, the gradual deterioration of entanglement due to dissipation and noise fed to the system by the environment, has emerged as a central concept. The present set of lectures is intended as a high-level, but self-contained, introduction into the fields of quantum noise and dissipation.In particular their influence on decoherence and applications pertaining to quantum information and quantum communication are studied, leading the nonspecialist researchers and the advanced students gradually to the forefront of research.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condizione: Neu. Neuware -Neutron spin echo (NSE) spectroscopy is the highest energy resolution neutron scattering technique available for examining a large area (in time and space) in condensed matter physics. This broad dynamic and spatial range is extensively exploited in the study of a wide range of scientific problems ranging from the dynamics of glasses, polymer melts, complex fluids and microemulsions to the elementary excitations in superfluid 4He and to ferromagnets and spin glasses. This book reviews the current status and future prospects in NSE spectroscopy describing the method, latest instrumentation and also the use of NSE in fundamental, hard- and soft-matter science. It provides first-hand information for researchers working in the fields touched by NSE. In addition, young researchers, PhD students and graduates interested in the method will obtain a comprehensive overview and guidelines to implementing the NSE technique.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 368 pp. Englisch.

Buch. Condizione: Neu. Neuware -As the media converges with the telecommunication industry leveraging content becomes key for both formerly separate industries. As new channels are offered and used to distribute various contents - from music to games, from text to videos - companies have to think about innovative ways to even more profit from providing the channels or from providing the content or from providing both. New business models are emerging that are made for leveraging content and finding their way to the customers. This book explains why and how more content leverage becomes reality.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Buch. Condizione: Neu. Neuware -The characterisation of materials and material systems is an essential aspect of materials science. A few decades ago it became obvious that, because the properties of materials depend so critically on the microstructure of their components, this characterisation must be determined to the atomic level. This means that the position - as well as the nature - of individual atoms has to be determined at 'critical' regions close to defects such as dislocations, interfaces, and surfaces. The great impact of advanced transmission electron microscopy (TEM) techniques became apparent in the area of semiconducting materials, where the nature of internal interfaces between silicon and the corresponding silicides could be identified, and the results used to enhance the understanding of the properties of the compounds studied. At that time, advanced TEM techniques existed predominantly in the US. However, advanced TEM instrumentation was not available in the ma terials science and solid-state science communities in Germany. This gap was bridged by the late Peter Haasen who, after a visit to the US, initiated a Priority Programme on Microstructural Characterisation at the Volkswagen Foundation (Hannover). The programme was in effect from 1985 to 1997 and supported a wide range of research projects - from fundamental, trendy, innovative projects to projects in applied materials science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 460 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book presents a rational scheme of analysis for the periodic and quasi-periodic solution of a broad class of problems within technical and celestial mechanics. It develops steps for the determination of sufficiently general averaged equations of motion, which have a clear physical interpretation and are valid for a broad class of weak-interaction problems in mechanics. The criteria of stability regarding stationary solutions of these equations are derived explicitly and correspond to the extremum of a special 'potential' function. Much consideration is given to applications in vibrational technology, electrical engineering and quantum mechanics, and a number of results are presented that are immediately useful in engineering practice. The book is intended for mechanical engineers, physicists, as well as applied mathematicians specializing in the field of ordinary differential equations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Buch. Condizione: Neu. Neuware -I have been asked to write a foreword to the next edition of the Vademecum of Clinical Bio chemistry renamed to Differential Diagnosis by Laboratory Medicine. The Editor in-Chief, Professor Dusan Mesko, conceived the idea of the Vademecum during a very intensely, in tellectually active period as a visiting Olga Havel Fellow from Slovak Republic at the Mayo Clinic in Rochester. It was here during his study stay that much of the conceptual planning and detailed realization was being completed. It was with much interest that I observed Professor Mesko in his effort, and I know while here he has gained admiration of those who had the privilege of interacting with him. When the first edition of the Vademecum ap peared and we received the copy for the Mayo Library and for myself, I was overcome with a genuine sense of joy. In this era of rapid information and the need to access usable infor mation book such as this cannot be but judged extremely useful. It is my hope that this work, which attests to the thoroughness of Professor Mesko's and his co-workers efforts will prove to be fruitful for the students quick reference, for clinicans and house officers lightening of burdens, particularly of on-call nights, and for the teaching staff as well to quickly access needed information. With these sentiments, we wish the authors and the book well and also hope that the potential widening circle of readers and users will benefit from the work pre sented.

Buch. Condizione: Neu. Neuware -North and South America share similar human and ecological histories and, increasingly, economic and social linkages. As such, issues of ecosystem functions and disruptions form a common thread among these cultures. This volume synthesizes the perspectives of several disciplines, such as ecology, anthropology, economy, and conservation biology. The chief goal is to gain an understanding of how human and ecological processes interact to affect ecosystem functions and species in the Americas. Throughout the text the emphasis is placed on habitat fragmentation. At the same time, the book provides an overview of current theory, methods, and approaches used in the analysis of ecosystem disruptions and fragmentation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Buch. Condizione: Neu. Neuware -The nature of the physical Universe has been increasingly better understood in recent years, and cosmological concepts have undergone a rapid evolution (see, e.g., [11], [2],or [5]). Although there are alternate theories, it is generally believed that the large-scale relationships and homogeneities that we see can only be explainedby having the universe expand suddenlyin a very early ¿in ationary¿ period. Subsequent evolution of the Universe is described by the Hubble expansion, the observation that the galaxies are ying away from each other. We can attribute di erent rates of this expansion to domination of di erent cosmological processes, beginning with radiation, evolving to matter domination, and, relatively recently, to vacuum domination (the Cosmological Constant term)[4]. We assume throughout that we will be relying as much as possible on observational data, with simulations used only for limited purposes, e.g., the appearance of the Milky Wayfrom nearbyintergalactic viewpoints. The visualization of large-scale astronomical data sets using xed, non-interactive animations has a long history. Several books and lms exist, ranging from ¿Cosmic View: The Universe in Forty Jumps¿ [3] by Kees Boeke to ¿Powers of 10¿ [6,13] by Charles and Ray Eames, and the recent Imax lm ¿Cosmic Voyage¿ [15]. We have added our own contribution [9], ¿Cosmic Clock,¿ which is an animation based entirely on the concepts and implementation described in this paper.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 376 pp. Englisch.
