Taschenbuch. Condizione: Neu. Neuware -A full century has passed since the sudden and tragically premature demise of Aleksandr Porfir'evich Borodin in 1887 at the age of 53, when he was following with phenomenal success the disparate careers of musician, composer, organic chemist, and pioneer in women's medical education. As a unique figure among the remarkable group of geniuses who suddenly appeared in Russia in the middle of the last century and explosively propelled that country into the mainstream of world culture in the arts, humanities, and sciences, it might have been expected that Borodin was the object of much research. There is no doubt that the Russian contribution to the amazing development of structural chemistry in the last century has tended to be underplayed, while that in the rest of Europe has received much more attention. One wonders, in particular, whether Borodin's name might not have appeared in the chemical pantheon, as have those of Mendeleev, Markovnikov, Menshutkin, and many other Russians, if the aldol condensation, which he was the first to discover and investigate, had been named the Borodin condensation. Straightening out the record is important; Figurovskii and Solov'ev's biography does much in this respect. Just as meritorious have been the scholarly and exhaustive efforts of Professors Charlene Steinberg and George B. Kauffman, who have made the Russian text accessible to the Western world in their accurate and engrossing translation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume brings together the advanced research results obtained by the European COST Action 2102 'Cross Modal Analysis of Verbal and Nonverbal Communication', primarily discussed at the PINK SSPnet-COST2102 International Conference on Analysis of Verbal and Nonverbal Communication and Enactment: The Processing Issues, held in Budapest, Hungary, in September 2010.The 40 papers presented were carefully reviewed and selected for inclusion in the book. The volume is arranged into two scientific sections. The first section, Multimodal Signals: Analysis, Processing and Computational Issues, deals with conjectural and processing issues of defining models, algorithms, and heuristic strategies for data analysis, coordination of the data flow and optimal encoding of multi-channel verbal and nonverbal features. The second section, Verbal and Nonverbal Social Signals, presents original studies that provide theoretical and practical solutions to the modelling of timing synchronization between linguistic and paralinguistic expressions, actions, body movements, activities in human interaction and on their assistance for an effective human-machine interactions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book is an updated and modified translation of the Russian edition of 1984. In the present edition, certain sections have been abridged (in particular, Sects. 6.1 and 8.3) and the bibliography has been expanded. There are more detailed discus sions of the group properties of integrable systems of equations of mathematical physics (Sect. 3.4) and of the Riemannian problem in the context of the infinite dimensional internal symmetry groups of these systems of equations. There is an extended discussion of the reasons for the acceleration and retardation of pulsars in connection with more recent achievements of X-ray astronomy. Part of the material of Chap. 8 of the Russian edition has been included in Chap. 7; thus the number of chapters has been reduced to seven. S. Chandrasekhar set for me an example of brilliant analytical penetration into the essence of physical problems, and my book touches on his work in many in stances. The results of modem quantum theories of strong fields are not presented, but they can be found in the fundamental monographs Quantwn Electrodynamics of Strong Fields by W. Greiner, B. Muller, J. Rafelski (Sprioger-Verlag, Berlin, Heidelberg, New York 1985) and Quantwn Effects in Intense External Fields [in Russian] by A. Grib, S. Mamaev, W. Mostepanenko (Energoatomizdat, Moscow 1988). This book was translated by Dr. N. M. Queen; I am very grateful to him. I thank sincerely H. Latta, C.-D. Bachem, V. Rehman, S. von Kalckreuth for preparing of the english manuscript.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Process automation provides a means to integrate people in a software development organization with the development process and the tools supporting that development. This new technology may significantly improve software quality and development productivity. However, as yet there is little practical experience in its day-to-day use.This book is for those who wish to explore the technology or are considering its adoption. The monograph discusses the underlying concepts, reviews in some detail two of the major process automation products, relates process automation to process improvement, and provides adoption guidelines. Special emphasis is on the process modeling language ProNet which is commercially available. The book is enriched by numerous examples, tables, and technical appendices.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Computers have changed typography and prepress as well as printing. Typefaces are manufactured by 'digital punch cutters' with a PC, not any more by punch cutters. Typefaces are constructed an output by a new technolgy, the so-called fonttechnology. The book by Peter Karow covers the whole area of it. It offers various chapters about (among others) issues like intelligent font scaling, kerning, quality of type, legibility, and problems of different output devices. It is interesting to read about Gutenberg setting, the font market, optical scaling, and last but not least a 'hand on' Kanjhi, the Chinese/Japanese Glyphs. Furthermore, Fonttechnology contains a number of valuable and instructive appendices. Almost everything one has to know about type and computers!Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 476 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The aim of this book is to describe contemporary analytical and semi analytical techniques for solving typical celestial-mechanics problems. The word 'techniques' is used here as a term intermediate between 'methods' and 'recipes'. One often conceives some method of solution of a problem as a general mathematical tool, while not taking much care with its computa tional realization. On the other hand, the word 'recipes' may nowadays be understood in the sense of the well-known book Numerical Recipes (Press et al. , 1992), where it means both algorithms and their specific program realiza tion in Fortran, C or Pascal. Analytical recipes imply the use of some general or specialized computer algebra system (CAS). The number of different CAS currently employed in celestial mechanics is too large to specify just a few of the most preferable systems. Besides, it seems reasonable not to mix the essence of any algorithm with its particular program implementation. For these reasons, the analytical techniques of this book are to be regarded as algorithms to be implemented in different ways depending on the hardware and software available. The book was preceded by Analytical Algorithms of Celestial Mechanics by the same author, published in Russian in 1980. In spite of there being much common between these books, the present one is in fact a new mono graph.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This text is an introduction to programming in general, and a manual for programming with the language Modula-2 in particular. It is oriented primarily towards people who have already acquired some basic knowledge of programming and would like to deepen their understanding in a more structured way. Neveltheless, an introductory chapter is included for the benefit of the beginner, displaying in a concise form some of the fundamental concepts of computers and their programming. The text is therefore also suitable as a self-contained tutorial. The notation used is Modula-2, which lends itself well for a structured approach and leads the student to a working style that has generally become known under the title of structured programming. As a manual for programming in Modula-2, the text covers practically all facilities of that language. Part 1 covers the basic notions of the variable, expression, assignment, conditional and repetitive statement, and array data structure. Together with Palt 2 which introduces the important concept of the procedure or subroutine, it contains essentially the material commonly discussed in introductory programming courses. Part 3 concerns data types and structures and constitutes the essence of an advanced course on programming. Palt 4 introduces the notion of the module, a concept that is fundamental to the design of larger programmed systems and to programming as team work. The most commonly used utility programs for input and output are presented as examples of modules.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -No single volume has been entirely devoted to the properties of magnetic lenses, so far as I am aware, although of course all the numerous textbooks on electron optics devote space to them. The absence of such a volume, bringing together in formation about the theory and practical design of these lenses, is surprising, for their introduction some fifty years ago has created an entirely new family of commercial instruments, ranging from the now traditional transmission electron microscope, through the reflection and transmission scanning microscopes, to co lumns for micromachining and microlithography, not to mention the host of experi mental devices not available commercially. It therefore seemed useful to prepare an account of the various aspects of mag netic lens studies. These divide naturally into the five chapters of this book: the theoretical background, in which the optical behaviour is described and formu lae given for the various aberration coefficients; numerical methods for calculat ing the field distribution and trajectory tracing; extensive discussion of the paraxial optical properties and aberration coefficients of practical lenses, il lustrated with curves from which numerical information can be obtained; a comple mentary account of the practical, engineering aspects of lens design, including permanent magnet lenses and the various types of superconducting lenses; and final ly, an up-to-date survey of several kinds of highly unconventional magnetic lens, which may well change the appearance of future electron optical instruments very considerably after they cease to be unconventional.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -In recent times a new dialogue has begun between the natural sciences and the humanities. This is particularly true of physics and philosophy, whose sphere of mutual interest expanded significantly with the advent of quantum mechanics. Among other topics, the discussion covers the evolution of theories, the role of mathematics in the physical sciences, the perception and cognition of nature and definitions of space and time. In contrast to the custom of the last two centuries, mathematics - the language of physics - is once again finding a respected place in the discourse of philosophers. The interdisciplinary communication between philosophers, mathematicians and physicists will be given new impetus by the thoughtful and wide-ranging contributions to this book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Eugene Wigner is one of the very few scientists that maysafely be describedas creators of 20th-century physics.This volume of his Collected Works is devoted to hiscontributions to nuclear energy. In his Introduction andAnnotations A.M. Weinberg surveys Wigner's contributions tonuclear-reaction physics and nuclear engineering, at thesame time giving a glimpse of the early history ofnuclear-reactor technology. Wigner himself gave a lively andcritical account, which is published in this volume for thefirst time. Furthermore the book contains forty-two reportsand memoranda from 1941 to 1945 and twelve of Wigner's manypatents relating to nuclear energy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 828 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The book treats the C -hydrocarbons and their secondary products as a contribution 4 to chemical engineering economics, applying this field of teaching and research to the technical processes for making and processing this group of products, so important to the chemical industry. As early as tpe 1950s the then director of the Institute for Technical Chemistry of the Berlin Technical University, Professor Herbert Kolbel, took the' initiative in the domain of Chemical Engineering Economics and began systematic studies of Project Engineering and Cost Estimation in connection with chemical plants. He also started a course on technical chemical processes in 1966. Properties, production procedures, plant equipment, and also the uses of technically interesting products are the central features of Chemical Technology. The information is to be found in the large encyclopedias of Technical Chemistry. On the other hand, Chemical Engineering Economics deals with all the economic conditions of usage of the raw materials, possibilities of utilizing co-products, and the integration of these products into definite production programmes, from the stand point of the chemical and technical fundamentals of the processes. Further important viewpoints are the costs of the products, taking into consideration important and variable influences on these costs, the situation and development of the market for the products and, of increasing significance, also the ecological global conditions for procuring raw materials and the production and marketing of the particular products.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Aroma biotechnology opens access to natural volatile flavors. Due to the attribute of 'naturalness' these aromas are the most valuable ingredients for foods, cosmetics and related products. The author describes biocatalyzed reactions and biogenetic routes leading to aroma and flavor compounds and he depicts in detail their utilisation in industrial scale processes. All the important topics, including de-novo-synthesis, genetic engineering, in vitro rDNA methods, laboratory requirements and techniques, upscaling, product recovery, profitability, and legal aspects are covered. R.G. Berger contributes his own experimental experience to all except one chapter and leads the reader into state-of-the-art aroma biotechnology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Before the late 1970s, interest in caffeine among both the general public and the scientific community was at a relatively low level for many years, even though it was recognized that caffeine was an al most universal component of the diet. The National Coffee Associa tion was supporting a continuing program of research, some re search was being conducted by a few of the largest companies selling coffee, and an occasional university researcher became inter ested in caffeine and conducted experiments, often on effects of caf feine in very high concentration in vitro on skeletal muscle fibres or on dividing cells. Since 1978, however, there has been a mighty up surge in both public and scientific interest in caffeine. It is interest ing to note that this was prompted not by discovery of hitherto un known effects or hazards of caffeine, but by the actions of a regulatory agency, the Food & Drug Administration (FDA) of the U. S. Public Health Service. The U. S. Congress passed new laws on foods and drugs in 1958. One of the provisions was for testing of food additives to assess risk to health. As it was clearly impracticable to require immediate test ing of all additives already in use, a list was drawn up of some hun dreds of additives that were generally recognized as safe (GRAS).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Condizione: Neu. Neuware -Environmental finance, particularly energy efficiency and renewable energy (EERE) finance, can and should serve as an interface to other sub-sectors of financial sector promotion such as microfinance, housing finance or agricultural finance. For example, existing clients of financial institutions include small and medium-sized enterprises and households, and these are often suffering from high energy prices or have no access to sustainable energy supply. At the same time, these clients are vulnerable to extreme weather events, and often hit hardest by the impact of climate change. There are many other examples which show that the financial sector has an enormous potential to support ¿green¿ investments. In order to tap this potential on a sustainable basis, it is important to have a sound understanding which role financial institutions can and should play.This book provides a blend of well-founded professional and scientific perspectives on the potential of Environmental finance in developing and transition countries.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Production theory and the theory of cost both belong to the central areas of business administration, for all considerations concerning the economic organization of industrial manufacturing processes start from these. Two developments in the past 30 years have had a considerable influence on the structure and the concentration on points of emphasis in this book. I am referring to findings from KOOPMANS' activity analysis and to the formulation by GUTENBERG of a production function concept that focuses on industrial production processes. Activity analysis has made it possible to develop, from a uniform approach, different types of production functions which describe the concrete principles of production in the productive sector of a business enterprise; this has created a common basis for all production concepts in business administration. The Gutenberg Production Function with its different kinds of adjustment to a changing output has opened up a flexibility to theoretical and practical considerations that gave rise to a large number of additional studies in this area. Considerations in cost theory were in particular need of considerable extensions in the direction of cost minimal combined adjustment processes. By means of the organization of its contents, this book will take both approaches into due account. In that way, it is vastly different from other books dealing with the same subject. As a matter of course, traditional analytical methods and ways of thinking also constitute a large part of the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -DYNAMIC ECONOMICS with increasing returns is extended tocope with economic growth, the business cycles and theirregular swings in the long-term development as differentaspects of the same dynamical system, the economic system'as a whole'.HUMAN CAPITAL emerges as the seminal concept: economicgrowth is in this dynamics causally reduced to the growth ofhuman capital and thus to the growth of exact scientificknowledge. An analysis of this knowledge shows that qualityeducation in hard sciences must be a prime target of futureeconomic policies.A CAUSAL STRUCTURE, new in economics, underlies the extendeddynamics. To enable students to study and to improve it, adetailled introduction to nonlinear causality is givenemphasizing the points relevant to this causal structure.NATIONAL ACCOUNTING and input-output dynamics are suggestedto be extended to include also the production prices andproduction of human capital and of human time, by using amethod of calculation indicated in detail in the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 392 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This monograph began as a study of the consequences of labor force effects, in cluding unemployment, for the distribution of earnings. I began by developing a model of job search. But following my previous work on the distribution of earnings, the search theory took a different form from the standard literature. Workers and firms were engaged in mutual search which effectively assigned workers to jobs. A number of open questions immediately became apparent, including the relation bet ween unemployment and inequality, the nature and costs of unemployment, and the role of choice. These quickly provided sufficient material for the monograph. I began work on the project in 1980 at Miami University of Ohio. I wish to thank my chairman there, William McKinstry, for the support I received during my last year there. My colleagues Donald Cymrot and James Moser provided some early com ments on the project and I am indebted to Joseph Simpson for extensive computer assistance.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The chapters in this book centre around one main theme, the concept of the machine and its use as metaphor in a variety of contexts. This concept is deeply rooted in western culture and is frequently used to interpret complex systems in nature and society. With the advent of electronic computers, the machine metaphor applied to thinking and the brain has becOIne even more pertinent. The idea of a machine has changed over time. In this book these transformations are made trans parent, various aspects of the machine metaphor are discussed and limitations and pitfalls of the metaphor are elaborated. The chapters are written in a non-technical fashion and are accessible to a large readership of scientists and also laymen interested in the scientific per spectives and logical foundations of the machine concept that has been so influential in western thinking. The idea of the book has its origin in a workshop held at the Sci entific Station in Abisko, Sweden, in May 1990, where several of the present authors participated. The meeting was organized and spon sored by the Swedish Council for Planning and Coordination of Re search (FRN). Since 1983, the FRN has actively promoted a series of such annual events at Abisko, all of which have been devoted to the exploration of various aspects of complex systems and their evolution.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Today, our world increasingly is conceived of as being molecular. An ever widening range of phenomena are described logically in terms of molecular properties and molecular interactions. The majority of known molecules are heterocyclic and heterocycles dominate the fields of biochemistry, medicinal chemistry, dyestuffs, photographic science and are of increasing importance in many others, including polymers, adhesives, and molecular engineering. Thus, the importance of heterocyclic chemistry continues to increase and this three volume work by Drs. R. R. Gupta, Mahendra Kumar and Vandana Gupta is a welcome addition to the available guides on the subject. Its scope places it in a useful niche between the single-volume texts and monographs of heterocyclic chemistry and the multivolume treatises. The authors have retained the well tried classical approach but have succeeded in placing their own individual spin on their arrangement. They have put together a well selected range from among the most important of the vast array offacts available. This factual material is ordered in a clear and logical fashion over the three volumes. The present work should be of great value to students-and practitioners of heterocyclic chemistry at all levels from the advanced undergraduate upwards. It will be of particular assistance in presenting a clear and modem view of the subject to those who use heterocycles in a variety of other fields and we wish it well.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 440 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The field of integrated- or guided-wave optics has experienced significant and continuous growth since its inception in the late 1960s. There has been a considerable increase in research and development activity in this field worldwide and some significant advances in the realization of working in tegrated optic devices and modules have been made in recent years. In fact, there have already been some commercial manufacturing and technical ap plications of such devices and modules. The guided-wave-acoustooptics involving Bragg interactions between guided optical waves and surface acoustic waves is one of the areas of in tegrated-optics that has reached some degree of scientific and technological maturity. This topical volume is devoted to an in-depth treatment of this emerging branch of science and technology. Presented in this volume are concise treatments on bulk-wave acoustooptics, guided-wave optics, and surface acoustic waves, and detailed studies of guided-wave acoustooptic Bragg diffraction in three promising material substrates, namely, LiNb0 , 3 ZnO/Si0 , and GaAs, the resulting wide band modulators and deflectors, 2 and applications. The chapters cover not only the basic principles and the oretical analysis, but also the design, fabrication, and measurement of the resulting devices and modules, and their applications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Concurrency and Nets is a special volume in the series 'Advances in Petri Nets'. Prepared as a tribute to Carl Adam Petri on the occasion of his 60th birthday, it is devoted to an outstanding personality and his pioneering and fruitful scientific work. Part I (70 pages of over 600) presents the congratulatory addresses and invited talks that were given at an Anniversary Colloquium. The contributions of this part honor Carl Adam Petri and his work from many different perspectives. Part II is a collection of invited papers discussing various aspects of the theme Concurrency and Nets. These papers are contributed partly by researchers that were or are still associated with the Petri Institute at GMD and partly by researchers whose scientific work deals with Net Theory or related system models. The topics range from basic theoretical aspects to application oriented methods.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 640 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Nitric Oxide (NO) an endogenous free radical, has been shown recently to mediate several important biological effects. It plays a neuro-transmitter like role in vascular endothelium, a scond-messenger role in N-methyl-D-aspartate (NMDA) responsive neurons in the central nervous system (CNS), a neurotoxic role after its release from these neurons, and a cytotoxic role after its release by macrophages. This volume reviews among other topics the basic chemistry and physical properties of S-nitrosothiols (RS-NO) and their biochemical mechanisms of action, NO synthase isozymes, NO synthase structure, mechanisms of NO synthesis, regulation of NOS expression and posttranslational modification, and mechanisms involving NO of CNS's damage in virus infections.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 108 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Since the discovery of the corpuscular nature of radiation by Planck more than fifty years ago the quantum theory of radiation has gone through many stages of development which seemed to alternate between spectacular success and hopeless frustration. The most recent phase started in 1947 with the discovery of the electromagnetic level shifts and the realization that the exist ing theory, when properly interpreted, was perfectly adequate to explain these effects to an apparently unlimited degree of accuracy. This phase has now reached a certain conclusion: for the first time in the checkered history of this field of research it has become possible to give a unified and consistent presen tation of radiation theory in full conformity with the principles of relativity and quantum mechanics. To this task the present book is devoted. The plan for a book of this type was conceived during the year 1951 while the first-named author (J. M. J. ) held a Fulbright research scholarship at Cambridge University. During this year of freedom from teaching and other duties he had the opportunity of conferring with physicists in many different countries on the recent developments in radiation theory. The comments seemed to be almost unanimous that a book on quantum electrodynamics at the present time would be of inestimable value to physicists in many parts of the world. However, it was not until the spring of 1952 that work on the book began in earnest.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 580 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Historically the search for the neural bases of behavior goes back a long way. Neuroethology, which is concerned with the experimental analysis ofthe releasing and control mech anisms of behavior, is a young discipline. Results from this multidisciplinary branch of research, which uses physical, chemical, and mathematical methods, have not yet been extensively treated in textbooks of neurophysiology and ethology. This book is intended as a first attempt to pose major questions of neuroethology and to demonstrate, by means of selected research examples, some of the ways by which these questions are being approached. Inevitably this cannot be a complete and in depth detailed treatment of all of the neurobiology examples, and I realize that such a selection is of a subjective nature. The overall goal ofthe book is to present an introduction. After outlining some of the very basic neurophysiological and ethological concepts (Chaps. 2 and 3), neuroethological questions and methods are demonstrated extensively by means of a particular example (Chap. 4). There are two reasons to choose the visually guided prey-catching and avoidance behavior of the Common Toad: (1) it is a system which I have inves tigated for about fifteen years and therefore know best, (2) the toad story is one of the most comprehensive neuro ethological approaches so far. Thus, it is possible here to outline the major concepts of neuroethology and to pose the basic questions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Silicon-Based Millimeter-Wave Devices describes field-theoretical methods for the design and analysis of planar waveguide structures and antennas. The principles and limitations of transit-time devices with different injection mechanisms are discussed, as are aspects of fabrication and characterization. The physical properties of silicon Schottky contacts and diodes are treated in a separate chapter. Two chapters cover the silicon/germanium devices: physics and RF properties of the heterobipolar transistor and quantum effect devices such as the resonant tunneling element are described. The integration of devices in monolithic circuits is explained and advanced technologies are presented along with the self-mixing oscillator operation. Finally sensor and system applications are considered.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book has a similar subject content to the author's previous Flow in Wood but with substantial updating due to the abundance of research in the wood science field since 1971. Several different concepts have been introduced, particularly in regard to wood-moisture relation ships. The role of water potential in the equilibria between wood and its humid and moist environments is considered. Two theories are introduced to explain the nonisothermal transport of bound water in the steady and unsteady states. As in the former text, the wood-. structure relationship is emphasized . . The author is especially grateful to Dr. C. Skaar for his careful and critical review of much of the manuscript and for the productive dis cussions of many of the concepts. Dr. T. E. Timell, the series editor, rendered major assistance in the preparation of Chap. 2 and in his editing of the manuscript. The author wishes to thank Dr. W. A. Cote, Mr. A. C. Day, and Mr. J. J. McKeon for providing electron micro graphs, Mr. G. A. Snyder for his photography of much of the art work, Dr. C. H. de Zeeuw for his advice in the field of wood anatomy, and Ms. Mary M. Siau for her careful rendition of the art work. Apprecia tion is extended to Miss Judy A. Barton and Mrs. Stephanie V. Micale for their work in typing and checking the manuscript. Mr. J.

Taschenbuch. Condizione: Neu. Neuware -The translation of this volume has been a long and sometime arduous journey giving nearly literal meaning to the Latin term translatus, meaning to carry across. In fact, it required many journeys both geographically, between Canada and Germany, and fig uratively, between German and English language, thought, and culture; between the mind of a German professor and that of his American colleague. Whether or not it was all worthwhile must be left to the reader's judgment, but let me outline the rationale for embarking on this venture. When the first German edition of this book appeared in 1980 it was acclaimed not only by German scholars but by those outside the German-speaking community as well. In fact, it received extremely favorable reviews, even in English-language journals, which is unusual for a foreign text. It was recognized that this was far more than just another text book on motivation. For one thing, it exposed and examined the multi faceted roots that have contributed to contemporary theory and research in motivation. The author skillfully examined the motivational concepts, theories, and research that have emanated from many areas of psychology such as learning theory, social psychol ogy, personality, psychoanalysis, and clinical psychology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 528 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The design and analysis of data structures and efficient algorithms has gained considerable importance in recent years. The concept of 'algorithm' is central in computer science, and 'efficiency' is central in the world of money. I have organized the material in three volumes and nine chapters. Vol. 1: Sorting and Searching (chapters I to III) Vol. 2: Graph Algorithms and NP-completeness (chapters IV to VI) Vol. 3: Multi-dimensional Searching and Computational G- metry (chapters VII and VIII) Volumes 2 and 3 have volume 1 as a common basis but are indepen dent from each other. Most of volumes 2 and 3 can be understood without knowing volume 1 in detail. A general kowledge of algorith mic principles as laid out in chapter 1 or in many other books on algorithms and data structures suffices for most parts of volumes 2 and 3. The specific prerequisites for volumes 2 and 3 are listed in the prefaces to these volumes. In all three volumes we present and analyse many important efficient algorithms for the fundamental computa tional problems in the area. Efficiency is measured by the running time on a realistic model of a computing machine which we present in chapter I. Most of the algorithms presented are very recent inven tions; after all computer science is a very young field. There are hardly any theorems in this book which are older than 20 years and at least fifty percent of the material is younger than 10 years.
