Taschenbuch. Condizione: Neu. Neuware - A rigorous and comprehensive text dealing primarily with the determinants of the pattern of trade gains from trade and trade policy. Spanning the old theories (the Ricardian hypothesis, the static and dynamic Heckscher-Ohlin model, the neofactor proportions and the neotechnology theories) it also contains the new theories (including various models of intra-industry trade and the dynamic models of endogenous growth and trade). Gains from trade and trade policy issues are comprehensively analysed. The various theories are presented verbally, geometrically and mathematically.

Buch. Condizione: Neu. Neuware - The latest developments in the area of microbial immunity are explored and explained in this timely volume, including new conceptual frameworks for the processing and presentation of peptides and nonpeptide antigens from microbes to T cells. Such experimental models have been instrumental in defining some of the pathways for generating protective immune responses against microbes. Other topics covered include: DAP 12, CD4+, Th1 and Th2 Cells, HIV infection, fusion, and tropism, and vaccine development.

Buch. Condizione: Neu. Neuware - An international symposium on `Ocean, River and Lakes: Energy and Substance Transfers at Interfaces' was held in Nantes, France in October 1996. It was the third International Joint Conference on Limnology and Oceanography which brings together specialists of both environments. Considered to be necessary in Europe, this confrontation of two different aspects of common subjects could produce innovative approaches. The main purpose concerns scientific researches relative to the interfaces between various aquatic environment compartments. The principal treated topics are bioavailability and mobility of substances, influence of biotic and abiotic factors on transfers, and fluxes at the interfaces. It is particularly interesting to note the contribution of Limnologists and Oceanographers on the impact of nutrients and pollutants, and flux quantification of river basin inputs. As well as scientists, this book is also of interest to all engineers and consultants involved in teaching and working in aquatic management, restoration and enhancement.

Buch. Condizione: Neu. Neuware - This monograph provides a comprehensive overview of recent advances in the field of vasopressin and oxytocin. In the summer of 1997, scientists from over 20 countries congregated in Montreal for the 1997 World Congress of Neurohypophysial Hormones, a conference that united the fields of vasopressin, neurohypophysis, and oxytocin in a single joint meeting that gave rise to the present book. The organization of a joint meeting was prompted by several recent developments. Specifically the molecular characterization of the vasopressin/oxytocin receptor family made it mandatory to adopt an integrated view and to discuss the vasopressin/oxytocin ligand/receptor family as a whole. To ensure emphasis on novelty, the conference focused on advances made over the last two years and also included important contributions by scientist that had not previously been associated with the vasopressin/oxytocin field.

Buch. Condizione: Neu. Neuware - The contents of this book are an expanded treatment of a set of presentations given at the first IEEE Workshop on Signal Propagation on Interconnects held Trnvemiindc, Germany, May 14- 16, 1997.

Taschenbuch. Condizione: Neu. Neuware - This book gives a unified and unique presentation of low gain and high gain design methodologies. In particular the development of low gain feedback design methodology is discussed. The development of both low and high gain feedback enhances the industrial relevance of modern control theory, by providing solutions to a wide range of problems that are of paramount practical importance. This detailed monograph provides the reader with a comprehensive insight into these problems: research results are examined and solutions to the problems are considered. Compared to that of high gain feedback, the power and significance of low gain feedback is not as widely recognized. The purpose of this monograph is to present some recent developments in low gain feedback, and its applications. Several low gain techniques are examined, including the control of linear systems with saturating actuators, semi-global stabilization of minimum phase input-output linearizable systems and H2 suboptimal control.

Buch. Condizione: Neu. Neuware - This volume on mathematical control theory contains high quality articles covering the broad range of this field. The internationally renowned authors provide an overview of many different aspects of control theory, offering a historical perspective while bringing the reader up to the very forefront of current research.

Buch. Condizione: Neu. Neuware - Since the fall of the Berlin Wall in 1989, Central European economies have been moving rapidly toward a common set of goals: political democracy, market-oriented economies and integration into the European and international business community. For businesses, Central Europe offers a unique window of opportunity and, in particular, two comparative advantages: a low-cost qualified workforce and stronger growth rates than mature Western European economies. This opportunity, seized by local entrepreneurs and foreign enterprises alike, is a significant competitive threat to companies not present in the region, or who have not found alternative strategies for increased growth and competitiveness. This book addresses economic transitions in Central Europe and analyzes the problems of Central European integration in the European Union.

Buch. Condizione: Neu. Neuware - In The Natural Background to Meaning Denkel argues that meaning in language is an outcome of the evolutionary development of forms of animal communication, and explains this process by naturalising the Locke-Grice approach. The roots of meaning are contained in observable regularities, which are manifestations of objective connections such as essences and causal relations. Denkel's particularistic ontology of properties and causation leads to a view of time that harmonises B-theory with transience. Time's passage, he argues, is a necessary condition of communication and meaning. The book connects some central topics in the philosophies of language, science and ontology, treating them within the framework of a single theory. It will interest not only professional philosophers doing research on meaning, universals, causation and time, but also students, who can consult it as a textbook examining Grice's theory of meaning.

Buch. Condizione: Neu. Neuware - Jeffrie G. Murphy's third collection of essays further pursues the topics of punishment and retribution that were explored in his two previous collections: Retribution, Justice and Therapy and Retribution Reconsidered. Murphy now explores these topics in the light of reflections on issues that are normally associated with religion: forgiveness, mercy, and repentance. He also explores the general issue of theory and practice and discusses a variety of topics in applied ethics - e.g., freedom of artistic expression, the morality of gambling, and the value of forgiveness in psychological counseling. As always, his perspective may be described as Kantian; and, indeed, this collection contains the first extended piece of Kant scholarship that he has done in years: a long essay on Kant on theory and practice.

Buch. Condizione: Neu. Neuware - Is there a universal biolinguistic disposition for the development of `basic' colour words This question has been a subject of debate since Brent Berlin and Paul Kay's Basic Color Terms: Their Universality and Evolution was published in 1969. Naming the Rainbow is the first extended study of this debate. The author describes and criticizes empirically and conceptually unified models of colour naming that relate basic colour terms directly to perceptual and ultimately to physiological facts, arguing that this strategy has overlooked the cognitive dimension of colour naming. He proposes a psychosemantics for basic colour terms which is sensitive to cultural difference and to the nature and structure of non-linguistic experience. Audience: Contemporary colour naming research is radically interdisciplinary and Naming the Rainbow will be of interest to philosophers, psychologists, anthropologists, and cognitive scientists concerned with: biological constraints on cognition and categorization; problems inherent in cross-cultural and in interdisciplinary science; the nature and extent of cultural relativism.

Buch. Condizione: Neu. Neuware - Robert Heeger has been professor of ethics at Utrecht University since 1977, both at the Faculty of Theology and at the Faculty of Philosophy. Since 1985, he has also been teaching at the Faculty of Veterinary Medicine. Before he came to Utrecht, he had worked at Uppsala University for many years. He has always stayed in close contact with his Swedish colleagues, and twice he was a visiting professor at Uppsala University. With his eastern-German background, his roots partly in Russia, his thesis on the Italian philosopher Gramsci and his interest in Anglo-American analytical philosophy he has a broad international orientation. It is no wonder, therefore, that he always felt much at home in the Societas Ethica, the European Society for Research in Ethics, which he served as its president from 1991 to 1995. Robert Heeger is primarily a teacher and excels as a discussion partner. With his sharp analytical mind and his great intellectual curiosity he not only exposes critically the weak. points in an argument, but often also brings up creative suggestions to improve it. Thus he has greatly influenced his many students (he co-supervised fourteen doctoral theses) and his colleagues, both in the Netherlands and abroad. Moreover, he was one of the first moral philosophers in the Netherlands, and even in Europe, to be involved in environmental ethics and in animal and veterinary ethics.

Buch. Condizione: Neu. Neuware - This book concerns two major topics, smart antenna systems and wireless local-area-networks (LANs). For smart antenna systems, it d- cusses the mechanics behind a smart antenna system, the setup of a smart antenna experimental testbed, and experimental and computer simulation results of various issues relating to smart antenna systems. For wireless LAN systems, it discusses the IEEE 802.11 worldwide wi- less LAN standard, the operation of a wireless LAN system, and some of the technical considerations that must be overcome by a wireless LAN system designer. These two topics are combined in the discussion of the Smart Wireless LAN (SWL) system, which was designed to achieve the benefits which smart antenna systems can provide for wireless LAN systems while still remaining compatible with the 802.11 wireless LAN standard. The design of SWL calls for the replacement of the conv- tional wireless LAN base station (which are called access points in the 802.11 documentation) with an SWL base station, while leaving the - dividual terminal operation as unchanged as possible.

Buch. Condizione: Neu. Neuware - According to the modal interpretation, the standard mathematical framework of quantum mechanics specifies the physical magnitudes of a system, which have definite values. Probabilities are assigned to the possible values that these magnitudes may adopt. The interpretation is thus concerned with physical properties rather than with measurement results: it is a realistic interpretation (in the sense of scientific realism). One of the notable achievements of this interpretation is that it dissolves the notorious measurement problem. The papers collected here, together with the introduction and concluding critical appraisal, explain the various forms of the modal interpretation, survey its achievements, and discuss those problems that have yet to be solved. Audience: Philosophers of science, theoretical physicists, and graduate students in these disciplines.

Buch. Condizione: Neu. Neuware - Education, Leadership and Business Ethics: New Essays on the Work of Clarence Walton includes a history and anecdotes of Clarence Walton's professional and personal life; a discussion of the controversial introduction of ethics into the field of management studies; contributions on a variety of subjects connected to leadership and business ethics from experts in the field; and critical essays reviewing Clarence's most recent work in social criticism. The book gives a history of the rise of the fields of business and society and business ethics, details the events leading to its acceptance in academic circles and gives personal accounts by Clarence Walton, one of the people most responsible for its creation. Intended target groups are students, former academic peers, and friends of Clarence Walton, as well as anyone interested in the history of business ethics or connected to Columbia University of America, or The American College.

Buch. Condizione: Neu. Neuware - This volume presents the proceedings of the Fourth Workshop on Multiaccess, Mobility and Teletraffic for Wireless Communications held in October 1998 in Washington, D.C. The focus of this workshop is to identify, present and discuss the theoretical and implementation issues critical to the design of wireless networks. To ensure proper network design and engineering, designers of wireless networks need to understand and address issues such as radio propagation, antenna, interference management, multiaccess, mobility, teletraffic, signalling and networking protocols. In fact, not only do these issues need to be understood and addressed, their interdependence and interactions also deserve to be examined closely. Therefore, the goal of this workshop is to present papers addressing these issues, with the hope of stimulating further collaboration among researchers of various disciplines in wireless communications. High-speed wireless networks such as wireless ATM and GSM with high-speed data services continue to attract much research and development efforts. The major challenges on the physical and link layers in these networks include radio design, interference management, resource allocation and multiaccess protocol. Several papers on these issues are presented here. As the availability of radio spectrum is limited, there is always a desire to ''maximize'' the spectral efficiency, for example, by diligent (and perhaps dynamic) re-use of frequency and cell layout, while guaranteeing a certain quality of service (QoS). A number of papers at this workshop address these topics.

Buch. Condizione: Neu. Neuware - This volume has its origin in the Seventeenth International Workshop on Maximum Entropy and Bayesian Methods, MAXENT 97. The workshop was held at Boise State University in Boise, Idaho, on August 4 -8, 1997. As in the past, the purpose of the workshop was to bring together researchers in different fields to present papers on applications of Bayesian methods (these include maximum entropy) in science, engineering, medicine, economics, and many other disciplines. Thanks to significant theoretical advances and the personal computer, much progress has been made since our first Workshop in 1981. As indicated by several papers in these proceedings, the subject has matured to a stage in which computational algorithms are the objects of interest, the thrust being on feasibility, efficiency and innovation. Though applications are proliferating at a staggering rate, some in areas that hardly existed a decade ago, it is pleasing that due attention is still being paid to foundations of the subject. The following list of descriptors, applicable to papers in this volume, gives a sense of its contents: deconvolution, inverse problems, instrument (point-spread) function, model comparison, multi sensor data fusion, image processing, tomography, reconstruction, deformable models, pattern recognition, classification and group analysis, segmentation/edge detection, brain shape, marginalization, algorithms, complexity, Ockham's razor as an inference tool, foundations of probability theory, symmetry, history of probability theory and computability. MAXENT 97 and these proceedings could not have been brought to final form without the support and help of a number of people.

Buch. Condizione: Neu. Neuware - Health care arguably is the single most regulated industry in industrial countries, and possibly in newly industrialized and developing countries as well. But what exactly is being regulated, what are the instruments used, and what are the effects and side-effects of such regulation Regulation of Health: Case Studies of Sweden and Switzerland seeks to resolve problems in answering these key questions regarding the health care sector in two countries - Sweden and Switzerland. The volume contains a series of studies that compare the regulation of health and health care in these two apparently very similar countries, in considerable detail. The contributing teams acquired a great deal of knowledge about health regulation in both countries; they also derived comparative predictions when regulation differs, using actual observations to check whether these predictions are borne out. These comparisons are based on the conditions prevailing in the mid-nineties.

Buch. Condizione: Neu. Neuware - Field-Programmable Analog Arrays brings together in one place important contributions and up-to-date research results in this fast moving area. Field-Programmable Analog Arrays serves as an excellent reference, providing insight into some of the most challenging research issues in the field.

Buch. Condizione: Neu. Neuware - If resources for HIV prevention efforts were truly unlimited, then this book would be en tirely unnecessary. In a world with limitless support for HIV prevention activities, one would simply implement all effective (or potentially effective) programs without regard to expense. We would do everything useful to prevent the further spread of the virus that has already claimed hundreds of thousands of lives in the United States and millions of lives worldwide. Unfortunately, funding for HIV prevention programs is limited. Even though the amount of available funding may seem quite large (especially in the United States), it is still fixed and not sufficient to meet all needs for such programs. This was very well illustrated in the summer of 1997 when over 500 community-based organizations applied for a combined total of $18 million of HIV prevention funding from the U.S. Centers for Disease Control and Prevention (CDC). Less than one-fifth ofthese organizations received support via this funding mechanism. Hence, although $18 million may seem like a large amount of money at first blush, it is not enough to meet all of the prevention needs that could be addressed by these community-based organizations.

Buch. Condizione: Neu. Neuware - Many books are available that detail the basic principles of the different methods of surface characterization. On the other hand, the scientific literature provides a resource of how individual pieces of research are conducted by particular labo- tories. Between these two extremes the literature is thin but it is here that the present volume comfortably sits. Both the newcomer and the more mature scientist will find in these chapters a wealth of detail as well as advice and general guidance of the principal phenomena relevant to the study of real samples. In the analysis of samples, practical analysts have fairly simple models of how everything works. Superimposed on this ideal world is an understanding of how the parameters of the measurement method, the instrumentation, and the char- teristics of the sample distort this ideal world into something less precise, less controlled, and less understood. The guidance given in these chapters allows the scientist to understand how to obtain the most precise and understood measu- ments that are currently possible and, where there are inevitable problems, to have clear guidance as the extent of the problem and its likely behavior.

Buch. Condizione: Neu. Neuware - Purpose of the Book This book presents an approach to improve the standard object-oriented pro gramming model. The proposal is aimed at supporting a larger range of incre mental behavior variations and thus promises to be more effective in mastering the complexity of today's software. The ability of dealing with the evolutionary nature of software is one of main merits of object-oriented data abstraction and inheritance. Object-orientation allows to organize software in a structured way by separating the description of different kinds of an abstract data type into different classes and loosely connecting them by the inheritance hierarchy. Due to this separation, the soft ware becomes free of conditional logics previously needed for distinguishing between different kinds of abstractions and can thus more easily be incremen tally extended to support new kinds of abstractions. In other words, classes and inheritance are means to properly model variations of behavior related to the existence of different kinds of an abstract data type. The support for extensi bility and reuse with respect to such kind-specific behavior variations is among the main reasons for the increasing popularity of object-oriented programming in the last two decades. However, this popularity does not prevent us from questioning the real effec tiveness of current object-oriented techniques in supporting incremental vari ations. In fact, this popularity makes a critical investigation of the variations that can actually be performed incrementally even more important.

Buch. Condizione: Neu. Neuware - Advances in optical technologies have made it possible to implement optical interconnections in future massively parallel processing systems. Photons are non-charged particles, and do not naturally interact. Consequently, there are many desirable characteristics of optical interconnects, e.g. high speed (speed of light), increased fanout, high bandwidth, high reliability, longer interconnection lengths, low power requirements, and immunity to EMI with reduced crosstalk. Optics can utilize free-space interconnects as well as guided wave technology, neither of which has the problems of VLSI technology mentioned above. Optical interconnections can be built at various levels, providing chip-to-chip, module-to-module, board-to-board, and node-to-node communications. Massively parallel processing using optical interconnections poses new challenges; new system configurations need to be designed, scheduling and data communication schemes based on new resource metrics need to be investigated, algorithms for a wide variety of applications need to be developed under the novel computation models that optical interconnections permit, and so on. Parallel Computing Using Optical Interconnections is a collection of survey articles written by leading and active scientists in the area of parallel computing using optical interconnections. This is the first book which provides current and comprehensive coverage of the field, reflects the state of the art from high-level architecture design and algorithmic points of view, and points out directions for further research and development.

Buch. Condizione: Neu. Neuware - Continuous cell lines derived from human cancers are the most widely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions of fundamental importance to the relevance of human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation 2. Do the cell lines accurately represent the histopathology of the original tumors 3. Do the cell lines accurately represent the molecular genetics of this type of cancer The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative of tumors at that site is naïve and misleading.

Buch. Condizione: Neu. Neuware - Many real-time systems rely on static scheduling algorithms. This includes cyclic scheduling, rate monotonic scheduling and fixed schedules created by off-line scheduling techniques such as dynamic programming, heuristic search, and simulated annealing. However, for many real-time systems, static scheduling algorithms are quite restrictive and inflexible. For example, highly automated agile manufacturing, command, control and communications, and distributed real-time multimedia applications all operate over long lifetimes and in highly non-deterministic environments. Dynamic real-time scheduling algorithms are more appropriate for these systems and are used in such systems. Many of these algorithms are based on earliest deadline first (EDF) policies. There exists a wealth of literature on EDF-based scheduling with many extensions to deal with sophisticated issues such as precedence constraints, resource requirements, system overload, multi-processors, and distributed systems. Deadline Scheduling for Real-Time Systems: EDF and Related Algorithms aims at collecting a significant body of knowledge on EDF scheduling for real-time systems, but it does not try to be all-inclusive (the literature is too extensive). The book primarily presents the algorithms and associated analysis, but guidelines, rules, and implementation considerations are also discussed, especially for the more complicated situations where mathematical analysis is difficult. In general, it is very difficult to codify and taxonomize scheduling knowledge because there are many performance metrics, task characteristics, and system configurations. Also, adding to the complexity is the fact that a variety of algorithms have been designed for different combinations of these considerations. In spite of the recent advances there are still gaps in the solution space and there is a need to integrate the available solutions. For example, a list of issues to consider includes: preemptive versus non-preemptive tasks, uni-processors versus multi-processors, using EDF at dispatch time versus EDF-based planning, precedence constraints among tasks, resource constraints, periodic versus aperiodic versus sporadic tasks, scheduling during overload, fault tolerance requirements, and providing guarantees and levels of guarantees (meeting quality of service requirements). Deadline Scheduling for Real-Time Systems: EDF and Related Algorithms should be of interest to researchers, real-time system designers, and instructors and students, either as a focussed course on deadline-based scheduling for real-time systems, or, more likely, as part of a more general course on real-time computing. The book serves as an invaluable reference in this fast-moving field.

Buch. Condizione: Neu. Neuware - Signal Recovery Techniques for Image and Video Compression and Transmission establishes a bridge between the fields of signal recovery and image and video compression. Traditionally these fields have developed separately because the problems they examined were regarded as very different, and the techniques used appear unrelated. Recently, though, there is growing consent among the research community that the two fields are quite closely related. Indeed, in both fields the objective is to reconstruct the best possible signal from limited information. The field of signal recovery, which is relatively mature, has long been associated with a wealth of powerful mathematical techniques such as Bayesian estimation and the theory of projects onto convex sets (to name just two). This book illustrates for the first time in a complete volume how these techniques can be brought to bear on the very important problems of image and video compression and transmission. Signal Recovery Techniques for Image and Video Compression and Transmission, which is written by leading practitioners in both fields, is one of the first references that addresses this approach and serves as an excellent information source for both researchers and practicing engineers.

Buch. Condizione: Neu. Neuware - Major advances in computing are occurring at an ever-increasing pace. This is especially so in the area of high performance computing (HPC), where today's supercomputer is tomorrow's workstation. High Performance Computing Systems and Applications is a record of HPCS'98, the 12th annual Symposium on High Performance Computing Systems and Applications. The quality of the conference was significantly enhanced by the high proportion of keynote and invited speakers. This book presents the latest research in HPC architecture, networking, applications and tools. Of special note are the sections on computational biology and physics. High Performance Computing Systems and Applications is suitable as a secondary text for a graduate-level course on computer architecture and networking, and as a reference for researchers and practitioners in industry.

Buch. Condizione: Neu. Neuware - Constructive mathematics is based on the thesis that the meaning of a mathematical formula is given, not by its truth-conditions, but in terms of what constructions count as a proof of it. However, the meaning of the terms `construction' and `proof' has never been adequately explained (although Kriesel, Goodman and Martin-Löf have attempted axiomatisations). This monograph develops precise (though not wholly formal) definitions of construction and proof, and describes the algorithmic substructure underlying intuitionistic logic. Interpretations of Heyting arithmetic and constructive analysis are given. The philosophical basis of constructivism is explored thoroughly in Part I. The author seeks to answer objections from platonists and to reconcile his position with the central insights of Hilbert's formalism and logic. Audience: Philosophers of mathematics and logicians, both academic and graduate students, particularly those interested in Brouwer and Hilbert; theoretical computer scientists interested in the foundations of functional programming languages and program correctness calculi.

Buch. Condizione: Neu. Neuware - Integrity and Internal Control in Information Systems is a state-of-the-art book that establishes the basis for an ongoing dialogue between the IT security specialists and the internal control specialists so that both may work more effectively together to assist in creating effective business systems in the future. Building on the issues presented in the preceding volume of this series, this book seeks further answers to the following questions: What precisely do business managers need in order to have confidence in the integrity of their information systems and their data What is the status quo of research and development in this area Where are the gaps between business needs on the one hand and research/development on the other; what needs to be done to bridge these gaps Integrity and Internal Control in Information Systems contains the selected proceedings of the Second Working Conference on Integrity and Internal Control in Information Systems, sponsored by the International Federation for Information Processing (IFIP) and held in Warrenton, Virginia, USA, in November 1998. It will be essential reading for academics and practitioners in computer science, information technology, business informatics, accountancy and edp-auditing.
