Buch. Zustand: Neu. Neuware -The technique of randomization has been employed to solve numerous prob lems of computing both sequentially and in parallel. Examples of randomized algorithms that are asymptotically better than their deterministic counterparts in solving various fundamental problems abound. Randomized algorithms have the advantages of simplicity and better performance both in theory and often is a collection of articles written by renowned experts in practice. This book in the area of randomized parallel computing. A brief introduction to randomized algorithms In the analysis of algorithms, at least three different measures of performance can be used: the best case, the worst case, and the average case. Often, the average case run time of an algorithm is much smaller than the worst case. 2 For instance, the worst case run time of Hoare's quicksort is O(n ), whereas its average case run time is only O(nlogn). The average case analysis is conducted with an assumption on the input space. The assumption made to arrive at the O(n logn) average run time for quicksort is that each input permutation is equally likely. Clearly, any average case analysis is only as good as how valid the assumption made on the input space is. Randomized algorithms achieve superior performances without making any assumptions on the inputs by making coin flips within the algorithm. Any analysis done of randomized algorithms will be valid for all possible inputs. 1052 pp. Englisch.

Buch. Zustand: Neu. Neuware -Patients aftlicted with thyroid eye disease or Graves' ophthamopathy (GO) may experience not only pain and visual loss, but also disfigurement. Full understanding of pathogenesis has been elusive, and treatment modalities are imperfect. As with other conditions, more effective intervention will follow only after a better understanding of pathogenesis is reached. The goal of this volume is to give an overview by leaders in the field of the present state of the art both in pathogenesis and clinical aspects of GO. Much attention has been directed towards determining which cells within the orbit are targets of the autoimmune process, and how these and other cells might participate in the local inflammatory process. It is now generally agreed that orbital fibroblasts, preadipocyte fibroblasts, and adipocytes are the targeted and activated cells in GO and that full-length TSH receptor (TSHr) is expressed in these cells. Further, there is growing consensus that this receptor is up-regulated in the orbit in GO, residing primarily in newly differentiated adipocytes. However, it is also evident, given a sufficiently sensitive assay, that TSHr is detectable in fibroblasts and adipocytes from the normal orbit and other anatomic sites, as well. It will be important to determine whether the observed increase in orbital TSHr expression itself initiates the orbital autoimmune process. Also to be decided is whether orbital lymphocytes from GO patients specifically recognize this receptor, and what factor or factors unique to Graves' dIsease might stimulate TSHr expression in orbital cells.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Zustand: Neu. Neuware -Mechanical methods of the activation of chemical processes are currently widely used for the synthesis of various compounds.

This method has been called soft mechanochemical synthesis.The monograph includes the papers published by the present authors. They describe the results of their investigations n the last two decades. New theoretical and experimental data on kinetics and mechanism of soft mechanochemical reactions in the mixtures of compounds mentioned above to give complex oxide compounds are presented. The description of new high energetic and high efficient mills providing effective occurrence of these reactions is delivered. The possibilities of applying soft mechanochemical synthesis for materials used in catalysts, material science, electronics, etc., are discussed. The advantages of the method proposed in comparison with other methods are demonstrated.The monograph is designed for researchers, engineers and technicians engaged in chemical and ceramic industry, for scientists and students specialized in the area of development, and application of new materials.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Buch. Zustand: Neu. Neuware -Beginning with the assumption that a justice motive exists, the author posits that belief in a just world influences the behavior of most people most of the time. This is true for all people of all ages and in all areas of life, for those struggling with their daily tasks as well as for those coping with a critical life event. An individual's belief in a just world is a necessary condition for a person's sense of fairness and mediates its adaptive effect on mental health.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Zustand: Neu. Neuware -The field of transplantation has grown exponentially over the last few decades, and leaders in the field may argue that we have seen only the tip of the iceberg. Perhaps in no other discipline is there a need for multidisciplinary dialogue, debate, and approaches to patient care. In preparing this book, we have attempted to introduce readers to a few of the key clinical and ethical issues confronting the field of transplantation today. In so doing, we recognize that the face of transplantation may change dramatically in the years to come. Nevertheless, the issues raised throughout this book will serve as a useful introduction to important clinical issues and as a catalyst for clinicians and researchers to expand the horizons of transplantation. Health professionals involved in evaluating and treating transplant patients must be knowledgeable of the indications for transplantation and patient outcomes and the process of evaluation and management. Chapters 1 and 2, focusing on solid organ transplantation and blood/marrow transplantation, provide this important contextual information. The next two chapters address what is often considered the most significant issue facing the field of transplantation - organ donation. While the number of patients needing transplantation has risen dramatically in recent years, the rate of organ donation has remained relatively stable. Chapter 3 highlights the many ethical issues surrounding the more general concept of organ donation, while Chapter 4 focuses specifically on the burgeoning interest in living organ donation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Buch. Zustand: Neu. Neuware -An internationally distinguished roster of contributors considers the state of the art of the discipline of archaeology at the turn of the 21st century and charts an ambitious agenda for the future. The chapters address a wide range of topics including paradigms, practice, and relevance of the discipline; paleoanthropology; fully modern humans; holocene hunter-gatherers; the transition to food and craft production; social inequality; warfare; state and empire formation; and the uneasy relationship between classical and anthropological archaeology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 532 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This volume applies ecological principles and guidelines to understand past and current land use and land management; and more importantly, endeavors to promote more ecologically sound approaches to future land use and management decisions. The volume incorporates case studies from a wide variety of disciplines and perspectives. The case studies explore past and current land use decisions, on both public and private lands, and include practical approaches and tools for land-use decision-making. Perhaps the most important feature of the book is the linking of ecological theory and principle with applied land use decision-making - the theoretical and empirical are joined through concrete case studies of actual land use decision-making processes. In this volume, readers will find a statement of fundamental ecological principles that are relevant for land use planning and management, coupled with multiple in-depth explorations of the application of these principles in action. In addition, most case studies describe specific tools and approaches for incorporating endeavors to join fundamental ecological knowledge with cutting edge application in order to both educate and provide concrete guidance for decision-making. The intended audience is broad and multidisciplinary, from undergraduate and graduate level courses in environmental studies to professional land use planners.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Buch. Zustand: Neu. Neuware -Global Production and Trade in East Asia focuses on the profound change that the traditional paradigm of production and international trade has undergone in the last two decades or so as a result of worldwide trade and investment liberalization. This ongoing transformation has been both aided and stimulated by advances in telecommunications, transportation, and information management. The liberalization of trade and investment on the one hand and advances in communications technology on the other have further promoted global production networks in which vertical stages of final goods are fragmented across countries. International fragmentation of production, which enables international division of labor not only in final products but also in vertically related components, is more evident than ever before.The book documents the process of international production fragmentation and trade in East Asian economies, studies the mechanics of the process, explores the theory behind the phenomenon, and identifies important policy implications. It focuses on production fragmentation and trade in East Asia because this is the part of the world where the phenomenon is most visible. With contribution by well-known international economics scholars from North America, Europe, and the Asia-Pacific, the book distinguishes itself with high global quality and rich regional content. It achieves a fine balance between theory, policy, and empirical work.This book will interest scholars of international trade, foreign investment and international business, regional specialists in East Asian economies, policymakers and advisors in international economic relations, and anyone else who follows important economic issues of globalization.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Buch. Zustand: Neu. Neuware -I came to vision science trying to solve an engineering problem: I was trying to come up with test and measurement methodologies for digital video systems. One of the metrics I wanted to use was some measurement of image quality. After some experiments and after an overview of the literature, I had to realize that simple computational metrics, such as the mean square error, are not very effective for this purpose. This led me to study notions of vision science and vision modeling. As an engineer, I found it fascinating. Vision science uses computational tools and modeling techniques that are very similar to what we use in signal processing, yet it brings you to a new domain that lies at the intersection of engineering, biology and cognitive psychology. Over the years, vision science has made tremendous contributions to engineering and to the field of image processing in particular. Such contributions include half toning matrices for the printing industry, color correction for digital cameras, quantization matrices for image coding. As imaging devices are becoming commodities, the impact of vision science is becoming even more significant. This book is meant to appeal to an engineering audience. It is an introduction to vision science and to the design and application of vision models in engineering. To achieve this goal, we have chosen to organize the book around the main components of vision models.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Buch. Zustand: Neu. Neuware -Non-destructive testing (NDT) systems can generate incomplete, incorrect or conflicting information about a flaw or a defect. Therefore, the use of more than one NDT system is usually required for accurate defect detection and/or quantification. In addition to a reduction in inspection time, important cost savings could be achieved if a data fusion process is developed to combine signals from multisensor systems for manual and remotely operated inspections. This gathering of data from multiple sources and an efficient processing of information help in decision making, reduce signal uncertainty and increase the overall performance of a non-destructive examination. This book gathers, for the first time, essays from leading NDT experts involved in data fusion. It explores the concept of data fusion by providing a comprehensive review and analysis of the applications of NDT data fusion. This publication concentrates on NDT data fusion for industrial applications and highlights progress and applications in the field of data fusion in areas ranging from materials testing in the aerospace industry to medical applications. Each chapter contains a specific case study with a theoretical part but also presents experimental results from a practical point of view. The book should be considered more as a pragmatic introduction to the applications of NDT data fusion rather than a rigorous basis for theoretical studies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Buch. Zustand: Neu. Neuware -This volume is an outgrowth of the Second International Workshop on Macroscopic Quantum Coherence and Computing held in Napoli, Italy, in June 2000. This workshop gathered a number of experts from the major Universities and Research Institutions of several countries. The choice of the location, which recognizes the role and the traditions of Naples in this field, guaranteed the participants a stimulating atmosphere. The aim of the workshop has been to report on the recent theoretical and experimental results on the macroscopic quantum coherence of macroscopic systems. Particular attention was devoted to Josephson devices. The correlation with other atomic and molecular systems, exhibiting a macroscopic quantum behaviour, was also discussed. The seminars provided both historical overview and recent theoretical ground on the topic, as well as information on new experimental results relative to the quantum computing area. The first workshop on this topic, held in Napoli in 1998, has been ennobled by important reports on observations of Macroscopic Quantum Coherence in mesoscopic systems. The current workshop proposed, among many stimulating results, the first observations of Macroscopic Quantum Coherence between macroscopically distinct fluxoid states in rf SQUIDs, 20 years after the Leggett's proposal to experimentally test the quantum behavior of macroscopic systems. Reports on observations of quantum behaviour in molecular and magnetic systems, small Josephson devices, quantum dots have also been particularly stimulating in view of the realization of several possible q-bits.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 476 pp. Englisch.

Buch. Zustand: Neu. Neuware -Control networks span a wide range of application areas.

Buch. Zustand: Neu. Neuware -Spectral Techniques in VLSI CAD have become a subject of renewed interest in the design automation community due to the emergence of new and efficient methods for the computation of discrete function spectra. In the past, spectral computations for digital logic were too complex for practical implementation. The use of decision diagrams for spectral computations has greatly reduced this obstacle allowing for the development of new and useful spectral techniques for VLSI synthesis and verification. Several new algorithms for the computation of the Walsh, Reed-Muller, arithmetic and Haar spectra are described. The relation of these computational methods to traditional ones is also provided.Spectral Techniques in VLSI CAD provides a unified formalism of the representation of bit-level and word-level discrete functions in the spectral domain and as decision diagrams. An alternative and unifying interpretation of decision diagram representations is presented since it is shown that many of the different commonly used varieties of decision diagrams are merely graphical representations of various discrete function spectra. Viewing various decision diagrams as being described by specific sets of transformation functions not only illustrates the relationship between graphical and spectral representations of discrete functions, but also gives insight into how various decision diagram types are related.Spectral Techniques in VLSI CAD describes several new applications of spectral techniques in discrete function manipulation including decision diagram minimization, logic function synthesis, technology mapping and equivalence checking. The use of linear transformations in decision diagram size reduction is described and the relationship to the operation known as spectral translation is described. Several methods for synthesizing digital logic circuits based on a subset of spectral coefficients are described. An equivalence checking approach for functional verification is described based upon the use of matching pairs of Haar spectral coefficients.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Zustand: Neu. Neuware -The area of spinal cord plasticity has become a very actively researched field. The spinal cord has long been known to organize reflex patterns and serve as the major transmission pathway for sensory and motor nerve impulses. However, the role of the spinal cord in information processing and in experience driven alterations is generally not recognized. With recent advances in neural recording techniques, behavioral technologies and neural tracing and imaging methods has come the ability to better assess the role of the spinal cord in behavioral control and alteration. The discoveries in recent years have been revolutionary. Alterations due to nociceptive inputs, simple learning paradigms and repetitive inputs have now been documented and their mechanisms are being elucidated. These findings have important clinical implications. The development of pathological pain after a spinal cord injury likely depends on the sensitization of neurons within the spinal cord. The capacity of the spinal cord to change as a function of experience, and adapt to new environmental relations, also affects the recovery locomotive function after a spinal cord injury. Mechanisms within the spinal cord can support stepping and the capacity for this behavior depends on behavioral training. By taking advantage of the plasticity inherent within the spinal cord, rehabilitative procedures may foster the recovery of function.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Zustand: Neu. Neuware -1 DATA ENVELOPMENT ANALYSIS Data Envelopment Analysis (DEA) was initially developed as a method for assessing the comparative efficiencies of organisational units such as the branches of a bank, schools, hospital departments or restaurants. The key in each case is that they perform feature which makes the units comparable the same function in terms of the kinds of resource they use and the types of output they produce. For example all bank branches to be compared would typically use staff and capital assets to effect income generating activities such as advancing loans, selling financial products and carrying out banking transactions on behalf of their clients. The efficiencies assessed in this context by DEA are intended to reflect the scope for resource conservation at the unit being assessed without detriment to its outputs, or alternatively, the scope for output augmentation without additional resources. The efficiencies assessed are comparative or relative because they reflect scope for resource conservation or output augmentation at one unit relative to other comparable benchmark units rather than in some absolute sense. We resort to relative rather than absolute efficiencies because in most practical contexts we lack sufficient information to derive the superior measures of absolute efficiency. DEA was initiated by Charnes Cooper and Rhodes in 1978 in their seminal paper Chames et al. (1978). The paper operationalised and extended by means of linear programming production economics concepts of empirical efficiency put forth some twenty years earlier by Farrell (1957).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.

Buch. Zustand: Neu. Neuware -Constraint Programming is a problem-solving paradigm that establishes a clear distinction between two pivotal aspects of a problem: (1) a precise definition of the constraints that define the problem to be solved and (2) the algorithms and heuristics enabling the selection of decisions to solve the problem.It is because of these capabilities that Constraint Programming is increasingly being employed as a problem-solving tool to solve scheduling problems. Hence the development of Constraint-Based Scheduling as a field of study.The aim of this book is to provide an overview of the most widely used Constraint-Based Scheduling techniques. Following the principles of Constraint Programming, the book consists of three distinct parts: The first chapter introduces the basic principles of Constraint Programming and provides a model of the constraints that are the most often encountered in scheduling problems.Chapters 2, 3, 4, and 5 are focused on the propagation of resource constraints, which usually are responsible for the 'hardness' of the scheduling problem.Chapters 6, 7, and 8 are dedicated to the resolution of several scheduling problems. These examples illustrate the use and the practical efficiency of the constraint propagation methods of the previous chapters. They also show that besides constraint propagation, the exploration of the search space must be carefully designed, taking into account specific properties of the considered problem (e.g., dominance relations, symmetries, possible use of decomposition rules).Chapter 9 mentions various extensions of the model and presents promising research directions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Buch. Zustand: Neu. Neuware -Recent advances have contributed to our understanding of how a plant-based diet confers many health advantages and how substances from plants may be effective in the prevention of specific cancers. The Ninth Annual Research Conference of the American Institute for Cancer Research has focused on the latest developments in several categories of nutrients of wide contemporary interests. The conference sessions included such topics as the effects of soy, green tea, selenium, wine, grapes, and spices in cancer prevention. This conference was held in Washington, D.C. on September 2nd and 3rd, 1999, and was entitled Nutrition and Cancer Prevention: New Insights Into the Roles of Phytochemicals.The discussion program included a session that was devoted to the current status of herbal products in relation to cancer prevention, in recognition of the increasing attention that complementary and alternative medicine has been receiving from the scientific community as well as the general public. A separate presentation addressed the issue of nutritional supplements and cancer prevention.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Buch. Zustand: Neu. Neuware - Dynamic Modeling of Musculoskeletal Motion introduces biomechanists to modern methods of modeling and analyzing dynamic biomechanical systems in three dimensions. Using vector kinematics, the reader is taught a systematic method which significantly reduces the complexity of working with multiple, moving limb segments in three dimensions. Operations which usually require the application of differential calculus are replaced by simple algebraic formulae. To derive dynamical equations of motion, a practical introduction to Kane's Method is given. Kane's Method builds upon the foundation of vector kinematics and represents one of the most exciting theoretical developments of the modern era. Together, these techniques enable biomechanists to decipher and model living systems with great realism, efficiency and accuracy. Interwoven with the theoretical presentation are chapters and examples which highlight the subtle differences between inanimate linkages and the biomechanical systems we seek to understand.

Buch. Zustand: Neu. Neuware -The first book on commutative semigroups was Redei's The theory of .finitely generated commutative semigroups, published in Budapest in 1956. Subsequent years have brought much progress. By 1975 the structure of finite commutative semigroups was fairly well understood. Recent results have perfected this understanding and extended it to finitely generated semigroups. Today's coherent and powerful structure theory is the central subject of the present book. 1. Commutative semigroups are more important than is suggested by the stan dard examples ofsemigroups, which consist ofvarious kinds oftransformations or arise from finite automata, and are usually quite noncommutative. Commutative of factoriza semigroups provide a natural setting and a useful tool for the study tion in rings. Additive subsemigroups of N and Nn have close ties to algebraic geometry. Commutative rings are constructed from commutative semigroups as semigroup algebras or power series rings. These areas are all subjects of active research and together account for about half of all current papers on commutative semi groups. Commutative results also invite generalization to larger classes of semigroups. Archimedean decompositions, a comparatively small part oftoday's arsenal, have been generalized extensively, as shown for instance in the upcoming books by Nagy [2001] and Ciric [2002].Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 456 pp. Englisch.

Buch. Zustand: Neu. Neuware - The 'First International Conference on Traditional Chinese Medicine: Science, Regulation and Globalization' was held from August 30 to September 2, 2000 at the University of Maryland at College Park, Maryland. There were approximately 250 participants from the Peoples Republic of China, Taiwan, Hong Kong and the United States. This objective of this conference was to promote international collaboration for the modernization of Traditional Chinese herbal medicines (TCM) and their introduction into the global health care system. It was mainly sponsored by the Ministry of Science and Technology of the People's Republic of China and the NllI National Center for Complementary and Alternative Medicine (NCCAM). It was organized by Dr. William Tai, then director of the Institute of Global Chinese Affairs at the University of Maryland and Dr. Yuan Lin, president of Marco Polo Technologies, Bethesda, MD. This conference was conceived by Dr. Tai two years earlier recognizing that this was an appropriate time and also the unique location of the University of Maryland. Today, there is a growing recognition of the of alternative medicine in modem societies and the rapid loss of importance knowledge about traditional methods for the treatment of the multitude of human illnesses found throughout the world. TCM has been in common use in China for thousands of years; and many of its formulations are well defined.

Buch. Zustand: Neu. Neuware - The growth of telecommunications has been largely based on mobile and data services in the past 10 years and the growth will continue. For instance, it is forecasted that after 2005 the mobile traffic turnover in Europe will exceed that of fixed telephone traffic and the penetration of Internet access through mobile will exceed that of fixed access. It is expected that the new value added services will be Internet-based and the IP traffic will outweigh the amount of traditional ISDN based telephone traffic. The transition from the existing telecommunications services to mobile and Internet based ones will change the service infrastructure as well as the customer and service management structures. In wireless communications there are several new standards being developed and implemented to improve the data transmission rate over radio channels, to combine both voice, packet data and multimedia services in the terminals and to improve the service quality and usability. Narrow band packet radio standards such as General Packet Radio Service (GPRS) and i-Mode are already operative and broadband IMT-2000 standards, also called as Third Generation (3G) Mobile, have been developed in Japan, Europe and US. At the same time Wireless LAN and Bluetooth technologies mature and provide short-range data access to terminal devices. The emerging new technologies create opportunities not only to incumbent teleoperators but also to new network operators, IT companies and new service and content providers.

Buch. Zustand: Neu. Neuware - The broadband wireless communications field is growing at an explosive rate, stimulated by a host of important emerging applications ranging from 3G, 4G and wireless LAN. Wideband CDMA and CDMA2000 will be used for 3G. OFDM+CDMA might be a good choice for 4G, CDMA overlay will possibly be used for new-generation broadband wireless LAN. For system planners and designers, the projections of rapidly escalating demand for such wireless services present major challenges and meeting these challenges will require sustained technical innovation on many fronts. The text of this book has been developed through years of research by the author and his graduate students at the University of Hong Kong. The aim of this book is to provide a R&D perspective on the field of broadband wireless communications by describing the recent research developments in this area and also by identifying key directions in which further research is needed. As a background, I presume that the reader has a thorough understanding of digital communications and spread spectrum/CDMA. The book is arranged into 13 chapters. In chapter 1, some key specifications of 3G WCDMA are described and discussed. These techniques include channel coding, rate matching, modulation and spreading, power control, cell search, transmit diversity, soft-handoff, and so son. In Chapter 2, the coherent RAKE reception of Wideband CDMA signals with complex spreading is considered. A dedicated pilot channel, which is separate from data channels, is used for the purpose of channel estimation.

Buch. Zustand: Neu. Neuware - A mere few years ago it would have seemed odd to propose a Handbook on the treatment of management problems within a sphere of uncertainty. Even today, on the threshold of the third millennium, this statement may provoke a certain wariness. In fact, to resort to exact or random data, that is probable date, is quite normal and con venient, as we then know where we are going best, where we are proposing to go if all occurs as it is conceived and hoped for. To treat uncertain information, to accept a new principle and from there determined criteria, without being sure of oneself and confiding only in the will to better understand objects and phenomena, constitutes and compromise with a new form of understanding the behaviour of current beings that goes even further than simple rationality. Economic Science and particularly the use of its elements of configuration in the world of management, has imbued several generations with an analytical spirit that has given rise to the elaboration of theories widely accepted by the international scientific community. In this work we are proposing something a little more modest: to use, in the best possible way, data and information that are available for drawing up and applying techniques and instruments that are useful for current reality within the world of businesses and institutions, in an attempt to mislead ourselves as little as possible.
