Buch. Condizione: Neu. Neuware -Since Fall of 1993, when we completed the manuscript of our book 'Semi conductor-Laser Physics' [W.W. Chow, S.W. Koch, and M. Sargent III (Springer, Berlin, Heidelberg, 1994)] many new and exciting developments have taken place in the world of semiconductor lasers. Novel laser and ampli fier structures were developed, and others, for example, the VCSEL (vertical cavity surface emitting laser) and monolithic MOPA (master oscillator power amplifier), made the transition from research and development to production. When investigating some of these systems, we discovered instances when de vice performance, and thus design depend critically on details of the gain medium properties, e.g., spectral shape and carrier density dependence of the gain and refractive index. New material systems were also introduced, with optical emission wave lengths spanning from the mid-infrared to the ultraviolet. Particularly note worthy are laser and light-emitting diodes based on the wide-bandgap group-III nitride and II~VI compounds. These devices emit in the visible to ultra-violet wavelength range, which is important for the wide variety of optoelectronic applications. While these novel semiconductor-laser materi als show many similarities with the more conventional near-infrared systems, they also possess rather different material parameter combinations. These dif ferences appear as band structure modifications and as increased importance of Coulomb effects, such that, e.g., excitonic signatures resulting from the at tractive electron-hole interaction are generally significantly more prominent in the wide bandgap systems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Time-evolution in low-dimensional topological spaces is a subject of puzzling vitality. This book is a state-of-the-art account, covering classical and new results. The volume comprises Poincaré-Bendixson, local and Morse-Smale theories, as well as a carefully written chapter on the invariants of surface flows. Of particular interest are chapters on the Anosov-Weil problem, C\*-algebras and non-compact surfaces. The book invites graduate students and non-specialists to a fascinating realm of research. It is a valuable source of reference to the specialists.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Buch. Condizione: Neu. Neuware -Quantum groups have been investigated rather deeply in mathematical physics over the last decade. Among the most prominent contributions in this area let us mention the works of V.G. Drinfeld, S.L. Woronowicz, S. Majid. Prob ability the ory on quantum groups has developed in several directions (see works of P. Biane, RL. Hudson and K.R Partasarathy, P.A. Meyer, M. Schürmann, D. Voiculescu). The aim of this book is to present several new aspects related to quantum groups: operator calculus, dual representations, stochastic processes and diffusions, Appell polynomials and systems in connection with evolution equations. Much of the ma terial is scattered throughout available literature, however, we have nowhere found in accessible form all of this material collected. The presentation of representation theory in connection with Appell systems is original with the authors. Stochastic processes (example: Brownian motion, diffusion processes, Levy processes) are in vestigated and several examples are presented. As a text the work is intended to be accessible to graduate students and researchers not specialised in quantum prob ability. We would like to acknowledge our colleagues P. Feinsilver, R Lenzceswki, D.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Buch. Condizione: Neu. Neuware -The book Complex Analysis through Examples and Exercises has come out from the lectures and exercises that the author held mostly for mathematician and physists . The book is an attempt to present the rat her involved subject of complex analysis through an active approach by the reader. Thus this book is a complex combination of theory and examples. Complex analysis is involved in all branches of mathematics. It often happens that the complex analysis is the shortest path for solving a problem in real circum stances. We are using the (Cauchy) integral approach and the (Weierstrass) power se ries approach . In the theory of complex analysis, on the hand one has an interplay of several mathematical disciplines, while on the other various methods, tools, and approaches. In view of that, the exposition of new notions and methods in our book is taken step by step. A minimal amount of expository theory is included at the beinning of each section, the Preliminaries, with maximum effort placed on weil selected examples and exercises capturing the essence of the material. Actually, I have divided the problems into two classes called Examples and Exercises (some of them often also contain proofs of the statements from the Preliminaries). The examples contain complete solutions and serve as a model for solving similar problems given in the exercises. The readers are left to find the solution in the exercisesj the answers, and, occasionally, some hints, are still given.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Brauer had already introduced the defect of a block and opened the way towards a classification by solving all the problems in defects zero and one, and by providing some evidence for the finiteness of the set of blocks with a given defect. In 1959 he discovered the defect group, and in 1964 Dade determined the blocks with cyclic defect groups.In 1978 Alperin and Broué discovered the Brauer category, and Broué and the author determined the blocks having a nilpotent Brauer category. In 1979, the author discovered the source algebra which determines all the other current invariants, representing faithfully the block ¿ and found its structure in the nilpotent blocks. Recently, the discovery by Rickard that all blocks with the same cyclic defect group and the same Brauer category have the same homotopic category focussed great interest on the new, loose relationship between blocks called Rickard equivalence.This book describes the source algebra of a block from the source algebra of a Rickard equivalent block and the source of the Rickard equivalence. 276 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - Today it is impossible to separate discussion of poverty from the priorities of state welfare. A hundred years ago, most working-class households avoided or coped with poverty without recourse to the state. The Poor Law after 1834 offered little more than a 'safety net' for the poorest, and much welfare was organised through charitable societies, self-help institutions and mutual-aid networks. Rather than look for the origins of modern provision, the author casts a searching light on the practices, ideology and outcomes of nineteenth-century welfare. This original and stimulating study, based upon a wealth of scholarship, is essential reading for all students of poverty and welfare. It also contains much to interest a wider readership.

Buch. Condizione: Neu. Neuware -Now in its fifth edition, Food Science remains the most popular and reliable text for introductory courses in food science and technology. This new edition retains the basic format and pedagogical features of previous editions and provides an up-to-date foundation upon which more advanced and specialized knowledge can be built. This essential volume introduces and surveys the broad and complex interrelationships among food ingredients, processing, packaging, distribution and storage, and explores how these factors influence food quality and safety. Reflecting recent advances and emerging technologies in the area, this new edition includes updated commodity and ingredient chapters to emphasize the growing importance of analogs, macro-substitutions, fat fiber and sugar substitutes and replacement products, especially as they affect new product development and increasing concerns for a healthier diet. Revised processing chapters include changing attitudes toward food irradiation, greater use of microwave cooking and microwaveable products, controlled and modified atmosphere packaging and expanding technologies such a extrusion cooking, ohmic heating and supercritical fluid extraction, new information that addresses concerns about the responsible management of food technology, considering environmental, social and economic consequences, as well as the increasing globalization of the food industry. Discussions of food safety an consumer protection including newer phychrotropic pathogens; HAACP techniques for product safety and quality; new information on food additives; pesticides and hormones; and the latest information on nutrition labeling and food regulation. An outstanding text for students with little or no previous instruction in food science and technology, Food Science is also a valuable reference for professionals in food processing, as well as for those working in fields that service, regulate or otherwise interface with the food industry.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 628 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - Neck pain is a common condition seen in the general practice of physiotherapy and occupational therapy. However, appropriate reading materials specifically intended for students therapists are rare. Therefore, this book is aimed to provide a comprehensive textbook for undergraduate rehabilitation sciences students, with the contribution of various experts in different medical disciplines. This book is comprised of five parts. Basic sciences such as anatomy, neurology and biomechanics of the cervical spine is included in Part One. Common pathologies, clinical investigation procedures, diagnostics imaging, surgery and orthotic management of cervical spinal disorders are discussed in Part Two. Occupational neck disorders and sports injuries causing cervical problems are discussed in Part Three, whereas the principles of rehabilitaion of patients with cervical spinal disorders are explained in Part Four. As therapists should be aware of the importance of evidence-based practice, current scientific research areas and outcome assessment of cervical spinal disorders are given in the last part of the book. Undergraduate rehabilitation sciences students, clinical therapists and other medical disciplines, such as medical students, nurses and orthopedics, will find this textbook informative and useful.

Buch. Condizione: Neu. Neuware -Physics of Planetary Rings describes striking structures of the planetary rings of Saturn, Uranus, Jupiter, and Neptune: Narrow ringlets, spiral waves, and a chain of clumps. The author has contributed essential ideas to the full understanding of planetary rings via the stability analysis of dynamical systems. The combination of a high-quality description, the set of interesting illustrations, as well as the fascinating and natural presentation will make this book of considerable interest to astronomers, physicists, and mathematicians as well as students. There is no competing text for this book so far.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 468 pp. Englisch.

Buch. Condizione: Neu. Neuware -In a stochastic network, such as those in computer/telecommunications and manufacturing, discrete units move among a network of stations where they are processed or served. Randomness may occur in the servicing and routing of units, and there may be queueing for services. This book describes several basic stochastic network processes, beginning with Jackson networks and ending with spatial queueing systems in which units, such as cellular phones, move in a space or region where they are served. The focus is on network processes that have tractable (closed-form) expressions for the equilibrium probability distribution of the numbers of units at the stations. These distributions yield network performance parameters such as expectations of throughputs, delays, costs, and travel times. The book is intended for graduate students and researchers in engineering, science and mathematics interested in the basics of stochastic networks that have been developed over the last twenty years. Assuming a graduate course in stochastic processes without measure theory, the emphasis is on multi-dimensional Markov processes. There is also some self-contained material on point processes involving real analysis. The book also contains rather complete introductions to reversible Markov processes, Palm probabilities for stationary systems, Little laws for queueing systems and space-time Poisson processes. This material is used in describing reversible networks, waiting times at stations, travel times and space-time flows in networks. Richard Serfozo received the Ph.D. degree in Industrial Engineering and Management Sciences at Northwestern University in 1969 and is currently Professor of Industrial and Systems Engineering at Georgia Institute of Technology.

Buch. Condizione: Neu. Neuware -The bibliography on electromagnetism is very rich and it may be necessary to justify our effort in writing a new text. The present text arose as a need when lecturing about the subject at Instituto Balseiro, in Bariloche, Argentina. We wanted to have a reference text for the most important topics covered in the course, which would also cover some aspects of interest for the applications of the concepts that the students have learned. follows one in classical mechan A course on electromagnetism usually ics. In the latter a brief introduction to the theory of relativity is normally included. During courses on electromagnetism this theory is traditionally pre sented again in brief form. This approach has the effect that, unless students later work on related topics, they do not acquire an appropriate knowledge of relativity. In this way, they lose perspective of the importance of one of the most beautiful and fascinating creations of physics in the twentieth cen tury. For this reason,we consider the properties of charges, currents and electromagnetic fields in vacuum, highlighting the relativistic transformation properties of each quantity. In spite of the advantages and elegance of the co variant formulation of electromagnetism, however, we avoid overemphasizing it. It is left for Chap. 9, where we present it after having developed vacuum electrodynamics. In this way, we minimize the risk of negatively impressing those students who are attracted to more concrete problems. 316 pp. Englisch.

Buch. Condizione: Neu. Neuware -The subject of the book is to present the modeling, parameter estimation and other aspects of the identification of nonlinear dynamic systems. The treatment is restricted to the input-output modeling approach. Because of the widespread usage of digital computers discrete time methods are preferred. Time domain parameter estimation methods are dealt with in detail, frequency domain and power spectrum procedures are described shortly. The theory is presented from the engineering point of view, and a large number of examples of case studies on the modeling and identifications of real processes illustrate the methods. Almost all processes are nonlinear if they are considered not merely in a small vicinity of the working point. To exploit industrial equipment as much as possible, mathematical models are needed which describe the global nonlinear behavior of the process. If the process is unknown, or if the describing equations are too complex, the structure and the parameters can be determined experimentally, which is the task of identification. The book is divided into seven chapters dealing with the following topics: 1. Nonlinear dynamic process models 2. Test signals for identification 3. Parameter estimation methods 4. Nonlinearity test methods 5. Structure identification 6. Model validity tests 7. Case studies on identification of real processes Chapter I summarizes the different model descriptions of nonlinear dynamical systems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 840 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book provides an up-to-date synthesis of the understanding of the interaction between the emission of nitrogen, its deposition and impact on the most important components of natural and semi-natural ecosystems. The work consists of contributions from internationally renowned research scientists. Individual chapters deal with the factors and processes related to nitrogen deposition and soils, non-forest vegetation communities, forest ecosystems, and surface waters. The assessment of these impacts is discussed in terms of setting critical loads. The book is aimed at researchers, advanced course students and policy makers/advisors involved with aspects of the impact of air pollution. 268 pp. Englisch.

Buch. Condizione: Neu. Neuware -Just suppose, for a moment, that all rings of integers in algebraic number fields were unique factorization domains, then it would be fairly easy to produce a proof of Fermat's Last Theorem, fitting, say, in the margin of this page. Unfortunately however, rings of integers are not that nice in general, so that, for centuries, math ematicians had to search for alternative proofs, a quest which culminated finally in Wiles' marvelous results - but this is history. The fact remains that modern algebraic number theory really started off with in vestigating the problem which rings of integers actually are unique factorization domains. The best approach to this question is, of course, through the general the ory of Dedekind rings, using the full power of their class group, whose vanishing is, by its very definition, equivalent to the unique factorization property. Using the fact that a Dedekind ring is essentially just a one-dimensional global version of discrete valuation rings, one easily verifies that the class group of a Dedekind ring coincides with its Picard group, thus making it into a nice, functorial invariant, which may be studied and calculated through algebraic, geometric and co homological methods. In view of the success of the use of the class group within the framework of Dedekind rings, one may wonder whether it may be applied in other contexts as well. However, for more general rings, even the definition of the class group itself causes problems. 280 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book originated in a symposium on business ethics that took place in the Faculty of Commerce at the University of Canterbury in September of 1997. Professor Werhane, who was a visiting Erskine Fellow, provided the keynote address, and many of the papers in this collection were originally presented at this symposium. We are grateful to Kluwer Publishers for the opportunity to publish these essays in their series on International Business Ethics. We want to thank the Olsson Center for Applied Ethics at the Darden School, University of Virginia, and the Erskine Trust and the Department of Management at the University of Canterbury for their support of Professor Werhane's fellowship, research for this text, and funding for its production. We especially want to thank Lisa Spiro, who copy-edited and prepared the manuscript for publication. INTRODUCTION AND OVERVIEW This book originated in a symposium on business ethics that took place in the faculty of commerce, at the University of Canterbury, in September 1997. Professor Werhane, who was a visiting Erskine Fellow, provided the keynote address. Contributions to the proceedings were. inter-disciplinary, spanning theory and practice. Subsequent contributions were obtained from within New Zealand and from Asia. The book starts off on rather a pessimistic note: the new managerialism (the kind of thing Scott Adams jokes about in the world-famous Dilbert cartoons) is economically suspect and psychologically damaging.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condizione: Neu. Neuware -European Populations: Unity in Diversity was the general theme of the 1999 European Population Conference, which convened in The Hague (The Netherlands) from 30 August to 3 September on behalf of the European Association for Population Studies (EAPS), The International Union for the Scientific Study of Population, (IUSSP), The Netherlands Interdisciplinary Demographic Institute (NIDI), Statistics Netherlands (SN), and The Netherlands Demographic Society (NVD).On the threshold of the third millennium, Europe is facing major and challenging demographic issues that, to a large extent, will shape its future. These challenges formed the basis for selecting special underlying themes for the plenary sessions at the conference. Four outstanding population experts were invited to present their views. Written versions of their presentations form the contents of this book.Dirk van de Kaa (The Netherlands) describes Europe and its population. Henri Leridon (France) addresses the question `How do Europeans plan their families '. Giuseppe Gesano (Italy) considers the relationship between demographic trends and the labour market, and Marek Okólski (Poland) writes about Europe's recent international migration history.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book shows, we believe, the breadth and the complexity of issues that econo mists now tackle in their analysis of the connections between the ecosystem and the economic system. The book offers contributions to such disparate issues as the value of preserving the wolf in Sweden and the proper distribution of permits in an effective global warming treaty. Because these questions remain at the fore front of important resource allocation problems that need to be confronted, it is only appropriate that they are represented in a book that intends to paint a picture, albeit certainly incomplete, of the vibrant and progressing state of environmental economics. The contributions cover five areas of environmental economics: policy instru ments, cost-benefit analysis, cost-efficiency, contingent valuation and experimental economics. Each area is worthy of a book by itself, but here we have made a point of focusing on problems that seem directly applicable to the pressing policy issues of today. Thus, the contributors address topics that are directly relevant to interna tional and regional policy making, as well as those that are linked to development of supporting information systems (e.g. resource accounting). In addition, the con tributions seek to provide high-level applications of measurement techniques as well as pertinent critiques of these methods. The next section provides a summary overview of the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 266 pp. Englisch.

Buch. Condizione: Neu. Neuware -A theoretical and empirical contribution to the quest for sustainability and environmental quality. The book examines the physical and economic aspects of flows of materials and products, as well as the policies and strategies designed to reduce the related resource depletion and environmental pollution. The `material-product chain' concept forms a general framework, defined as a system of linked flows of materials and products that support the provision of a certain service. Various economic models of material-product chains are studied, both theoretical and applied, such as static optimisation, dynamic simulation and general equilibrium models. Applications to metals, rain gutters and window frames are described.Audience: Readers in universities, research organizations and policy institutes interested in the environment, economics and government policy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Buch. Condizione: Neu. Neuware -Continuing the (neo-)classical tradition of von Thünen, Launhardt, Weber, Palander, and Lösch this book offers a fresh approach to the location of industries and other economic activities, of market areas, spatial price distribution, locational specialization, urban and transportation systems, and spatial interaction in general. It uses elementary economic reasoning supported by simple mathematical models, some classical, some new. The mathematical methods are presented in numbered Mathematical Notes. The author has been active in this field since 1950.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 214 pp. Englisch.

Buch. Condizione: Neu. Neuware -Since the building of all the Universe is perfect and is cre ated by the wisdom Creator, nothing arises in the Universe in which one cannot see the sense of some maXImum or mInImUm Euler God moves the Universe along geometrical lines Plato Mathematical models of most closed physical systems are based on vari ational principles, i.e., it is postulated that equations describing the evolu tion of a system are the Euler~Lagrange equations of a certain functional. In this connection, variational methods are one of the basic tools for studying many problems of natural sciences. The first problems related to the search for extrema appeared as far back as in ancient mathematics. They go back to Archimedes, Appolonius, and Euclid. In many respects, the problems of seeking maxima and minima have stimulated the creation of differential calculus; the variational prin ciples of optics and mechanics, which were discovered in the seventeenth and eighteenth centuries, gave impetus to an intensive development of the calculus of variations. In one way or another, variational problems were of interest to such giants of natural sciences as Fermat, Newton, Descartes, Euler, Huygens, 1. Bernoulli, J. Bernoulli, Legendre, Jacobi, Kepler, La grange, and Weierstrass.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 564 pp. Englisch.

Buch. Condizione: Neu. Neuware -Electron holography, a two-step imaging method taking advantage of light and electrons, has been employed for fundamental experiments in physics as well as for high-precision measurements in microscopy. It continues to be advanced in its applications though the speed of the development is not high but steady together with technical improvements of both the coherent electron beam and the reconstruction system. Progress has been made since the publication of the first edition of this book in 1993, and this second edi tion with new results integrated is herewith made available. I hope that the present monograph will help develop this interesting field of electron interference further. Hatoyama Akira Tonomura December 1998 v Preface to the First Edition Electron holography has recently paved a new way for observing and meas uring microscopic objects and fields that were previously inaccessible em ploying other techniques. Full use is made of the extremely short wave length of electrons, enabling electron holography to have a great impact on fields ranging from basic science to industrial applications. This book will provide an overview of the present state of electron holography for scien tists and engineers entering the field. The principles, techniques and appli cations which have already been developed, as well as those which are ex pected to arise in the near future, will be discussed.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Buch. Condizione: Neu. Neuware -A focus on reasons for action and practical reason is the perspective chosen by many contemporary legal philosophers for the analysis of some central questions of their discipline. This book offers a critical evaluation of that approach, by carefully examining the empirical, logical and normative problems hidden behind the concepts of `reason for action' and `practical reasoning'. Unlike most other works in this field, it is a meta-theoretical study which analyses and compares how different theories use the notion of reason in their reconstruction of problems concerning issues such as normativity, the acceptance of norms, or the justification of judicial decisions. This book is directed primarily to scholars specializing in legal theory and concerned with the contribution practical philosophy can make to it, but it also contains important arguments and insights for all those interested in the controversy between legal positivists and their critics, in the theory of human action or in reason-based practical theories in general.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Condizione: Neu. Neuware -In May 1998, a distinguished group of philosophers met in Munich to discuss the rationality of theism. This volume is a collection of the papers read at that conference. While in recent years the rationality of theistic belief has been widely discussed, the Munich conference was an event of some moment in the history of philosophical dialogue: for the first time German- and English-speaking philosophers of religion, representatives of both the Continental and the Anglo-Saxon traditions, joined together to grapple with a common philosophical theme. This multiplicity of perspectives brought a unique richness to the analysis of rationality that no one tradition by itself could provide. Readers will find that richness displayed in the pages of this book. Professional philosophers will find here a great deal to stimulate and challenge them; but graduate students, capable undergraduates, and all others with a serious interest in the philosophy of religion will be well rewarded for their efforts to come to grips with these thought-provoking papers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Condizione: Neu. Neuware -It is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision.Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. Rather, common practice is to categorize them under the heading `stratigraphic excavation'. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time - a point little appreciated by modern archaeologists.Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils. The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously. Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques.Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history. This text will appeal to all archaeologists, from graduate students to seasoned professionals, who want to learn more about the backbone of archaeological dating.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.
