Buch. Condición: Neu. Neuware -The aim of this book is to provide researchers in economics, finance, and statistics with an up-to-date introduction to applying Bayesian techniques to empirical studies. It covers the full range of the new numerical techniques which have been developed over the last thirty years, notably: Monte Carlo sampling, antithetic replication, importance sampling, and Gibbs sampling. The author covers both advances in theory and modern approaches to numerical and applied problems. The book includes applications drawn from a variety of different fields within economics and also provides a quick overview to the underlying statistical ideas of Bayesian thought. The result is a book which presents a roadmap of applied economic questions that can now be addressed empirically with Bayesian methods. Consequently, many researchers will find this a readily readable survey of this growing research topic.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Buch. Condición: Neu. Neuware -'Prove It With Figures' displays some of the tools of the social and statistical sciences that have been applied to the proof of facts in the courtroom and to the study of questions of legal importance. It explains how researchers can extract the most valuable and reliable data that can conveniently be made available, and how these efforts sometimes go awry. In the tradition of Zeisel's 'Say It with Figures,' a standard in the field of social statistics since 1947, it clarifies, in non-technical language, some of the basic problems common to all efforts to discern cause-and-effect relationships. Designed as a textbook for law students who seek an appreciation of the power and limits of empirical methods, the work also is a useful reference for lawyers, policymakers, and members of the public who would like to improve their critical understanding of the statistics presented to them. The many case histories include analyses of the death penalty, jury selection, employment discrimination, mass torts, and DNA profiling. Hans Zeisel was Professor of Law and Sociology Emeritus at the University of Chicago, where he pioneered the application of social science to the law. Earlier, he had a distinguished career in public opinion and market research. He has written on a wide variety of topics, ranging from research methodology and history to law enforcement, juries, and Sheakespeare. He was elected Fellow of the American Statistical Assoication and the American Association for the Advancement of Science, and in 1980 he was inducted into the Market Research Hall of Fame. David Kaye is Regents Professor at the Arizona State University, where he teaches evidence and related topics. An author of several law textbooks and treatises, his work also has appeared in journals ofSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Buch. Condición: Neu. Neuware -Although not evident to all, many people have been waiting more than a decade for The SGML FAQ Book by Steve DeRose. It has been 'brewing' for a long time, with many hours, months, years of research talking to people, gathering their ideas, listening to their frustrations, applauding their successes. Only Steve with his experience, credentials, wit, and enthusiasm for the subject could have written this book. But it is also a measure of the success and maturity of ISO 8879 and its amazing longevity that allows an 'SGMLer' to write such a book. We can now laugh at ourselves, even disclose our mistakes without fear of the other guy. While most would not recognize it, the revolution known as the World Wide Web would not have happened without a non-proprietary, easy, and almost 'portable way to create and distribute documents across a widely disparate set of computers, networks, even countries. HTML, an SGML application, enabled this and as a result the world and the SGML community will never be the same. For some the term SGML means order, management, standards, discipline; to others, the term brings images of pain, confusion, complexity, and pitfalls. To all who have engaged in it, the Standard means hard work, good friends, savings in terms of time, money, and effort, a sense of accomplishment and best of all - fun. This book adds immeasurably to all of these. Enjoy the quote from Through Looking by Lewis Carroll as much as we have.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Condición: Neu. Neuware -Entropy optimization is a useful combination of classical engineering theory (entropy) with mathematical optimization. The resulting entropy optimization models have proved their usefulness with successful applications in areas such as image reconstruction, pattern recognition, statistical inference, queuing theory, spectral analysis, statistical mechanics, transportation planning, urban and regional planning, input-output analysis, portfolio investment, information analysis, and linear and nonlinear programming.While entropy optimization has been used in different fields, a good number of applicable solution methods have been loosely constructed without sufficient mathematical treatment. A systematic presentation with proper mathematical treatment of this material is needed by practitioners and researchers alike in all application areas. The purpose of this book is to meet this need. Entropy Optimization and Mathematical Programming offers perspectives that meet the needs of diverse user communities so that the users can apply entropy optimization techniques with complete comfort and ease. With this consideration, the authors focus on the entropy optimization problems in finite dimensional Euclidean space such that only some basic familiarity with optimization is required of the reader.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 358 pp. Englisch.

Buch. Condición: Neu. Neuware -As one of the most quantitative of ecological subdisciplines, resource competition is an important, central area of ecology. Recently research into this area has increased dramatically and resource competition models have become more complex. The characterisation of this phenomenon is therefore the aim of this book. Resource Competition seeks to identify the unifying principles emerging from experimental and theoretical approaches as well as the differences between organisms, illustrating that greater knowledge of resource competition will benefit human and environmental welfare. This book will serve as an indispensable guide to ecologists, evolutionary biologists and environmental managers, and all those interested in resource competition as an emerging discipline.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condición: Neu. Neuware -In the preliminary stage of designing new structural hardware that must perform a given mission in a fluctuating load environment, there are several factors the designers should consider. Trade studies for different design configurations should be performed and, based on strength and weight considerations, among others, an optimum configuration selected. The selected design must be able to withstand the environment in question without failure. Therefore, a comprehen sive structural analysis that consists of static, dynamic, fatigue, and fracture is necessary to ensure the integrity of the structure. During the past few decades, fracture mechanics has become a necessary discipline for the solution of many structural problems. These problems include the prevention of failures resulting from preexisting cracks in the parent material, welds or that develop under cyclic loading environment during the life of the structure. The importance of fatigue and fracture in nuclear, pressure vessel, aircraft, and aerospace structural hardware cannot be overemphasized where safety is of utmost concern. This book is written for the designer and strength analyst, as well as for the material and process engineer who is concerned with the integrity of the structural hardware under load-varying environments in which fatigue and frac ture must be given special attention. The book is a result of years of both acade mic and industrial experiences that the principal author and co-authors have accumulated through their work with aircraft and aerospace structures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.

Buch. Condición: Neu. Neuware -The first edition of Advances in the Microbiology and Biochemistry of Cheese and Fermented Milk was aimed at the gap in the literature between the many excellent technical texts on the one hand, and the widely scattered scientific literature on the other. We tried to present the state of the art in pre competitive research in a predigested, yet scientifically coherent form, and relate it to the marketable properties of fermented dairy products. In this way, researchers could use the book to mentally step back from their specializations and see how far they had progressed as a community; at the same time we hoped that R&D-based companies could use it to assess the utility (or lack of it) of the research output in setting out their research acquisition strategy for product improvement and innovation. In a sense, the first edition could claim to have initiated Technology Foresight in its limited field before Government caught the idea, and it certainly gave the science base an opportunity to display its talents and resources as a potential source of wealth creation, well before this became an 'official' function of publicly funded science and technology. Thus, the first edition was intended as a progressive move within the growing science and technology literature, and judged by its market success, it seems to have served precisely that purpose. 388 pp. Englisch.

Buch. Condición: Neu. Neuware -The first edition of Cold and Chilled Storage Technology was prepared at a time when great changes were taking place in the industry that were hard to put into clear perspective. For example, the CFClozone layer problem was identified, the Montreal Protocol was signed and experts from many disci plines were already proposing 'solutions' to the problems seen at the time. Not only were there the usual differences in approach to the problems, there were different understandings of the problems themselves. For in stance, some authoritative voices were saying HCFC 22 was 'part of the solution, not part of the problem' and recommending it as the main refrig erant for the future, others said the opposite. As editor, I have taken the view that this should be a 'reference book' and, as such, it should contain information that points in the direction of tried and proven good practice. To avoid the risk of misdirecting readers, I decided that the CFC issue was too unclear to be usefully discussed in the first edition and left it out altogether. This was the main criticism of the first edition at the time of its publication but, in view of the developments since then, I stand by my decision to avoid premature comment in that instance. The matter is discussed in this edition in Chapters 4 and 7, which include summaries of other related factors, in a way that was certainly not possible in 1989.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condición: Neu. Neuware -The work of 47 contributors from the U.S., Canada, and Israel, the Sourcebook gives special attention to the complexity of the social support construct, expanding the field's theoretical base by seriously reappraising social support research in the context of findings from other fields of psychology and related disciplines. Personality processes are specified to account for observed associations between social support and physical well-being. Several new studies are included which illustrate empirical approaches to exploring these processes. And key contributions highlight the great strides made in understanding the links among personal dispositions, situational contexts, and potentially supportive transactions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 532 pp. Englisch.

Buch. Condición: Neu. Neuware -Aversive behaviors have greater influence on social interactions than is generally acknowledged, determining personal satisfaction, interpersonal attraction, choice of partners, and the course of relationships. What motivates aversive behaviors To what extent do they obtain desired outcomes In what ways are they unnecessary and destructive How do other people respond, emotionally and behaviorally These are just a few of the many interesting questions addressed by the 16 respected researchers who contribute to Aversive Interpersonal Behaviors. Nine chapters give this heretofore neglected subject the attention it is due, probing a dark side of interpersonal relationships to understand both its destructive and adaptive nature.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Condición: Neu. Neuware -Faced with the challenge of solving hard optimization problems that abound in the real world, classical methods often encounter great difficulty - even when equipped with a theoretical guarantee of finding an optimal solution. Vitally important applications in business, engineering, economics and science cannot be tackled with any reasonable hope of success, within practical time horizons, by solution methods that have been the predominant focus of academic research throughout the past three decades (and which are still the focus of many textbooks). The impact of technology and the advent of the computer age have presented us with the need (and opportunity) to solve a range of problems that could scarcely have been envisioned in the past. Weare confronted with applications that span the realms of resource planning, telecommunications, VLSI design, fmancial analysis, scheduling, space planning, energy distribution, molecular engineering, logistics, pattern classification, flexible manufacturing, waste management, mineral exploration, biomedical analysis, environmental conservation and scores of others.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 408 pp. Englisch.

Buch. Condición: Neu. Neuware - Symbolic Analysis in Analog Integrated Circuit Design provides an introduction to computer-aided circuit analysis and presents systematic methods for solving linear (i.e. small-signal) and nonlinear circuit problems, which are illustrated by concrete examples. Computer-aided symbolic circuit analysis is useful in analog integrated circuit design. Analytic expressions for the network transfer functions contain information that is not provided by a numerical simulation result. However, these expressions are generally extremely long and difficult to interpret; therefore, it is necessary to be able to approximate them guided by the magnitude of the individual circuit parameters. Engineering has been described as `the art of making approximations'. The inclusion of symbolic analysis in analog circuit design reduces the implied risk of ambiguity during the approximation process. A systematic method based on the nullor concept is used to obtain the basic feedback transistor amplifier configurations. Approximate expressions for the locations of poles and zeros for linear networks are obtained using the extended pole-splitting technique. An unusual feature in Symbolic Analysis in Analog Integrated Circuit Design is the consistent use of the transadmittance element with finite (linear or nonlinear) or infinite (i.e. nullor) gain as the only requisite circuit element. The describing function method is used to obtain approximate symbolic expressions for the harmonic distortion generated by a soft or hard transconductance nonlinearity embedded in an arbitrary linear network. The design and implementation of a program (i.e. CASCA) for symbolic analysis of time-continuous networks is described. The algorithms can also be used to solve other linear problems, e.g. the analysis of time-discrete switched-capacitor networks. Symbolic Analysis in Analog Integrated Circuit Design serves as an excellent resource for students and researchers as well as for industry designers who want to familiarize themselves with circuit analysis. This book may also be used for advanced courses on the subject.

Buch. Condición: Neu. Neuware - This book has been written to ensure that it will be of benefit to industrial analysts. Most chapters explain some of the relevant theory as well as give some historical references to place the technique in its proper context. In addition the book should appeal to academic scientists who require a good source of applications and a good set of references. Since lipids have many uses the appeal of the book will extend from the food industry to the pharmaceutical industry. R.

Buch. Condición: Neu. Neuware - Switched-Current Design and Implementation of Oversampling A/D Converters discusses the switched-current (SI) technique and its application in oversampling A/D converters design. The SI technique is an analog sampled-data technique that fully exploits the digital CMOS process. Compared with the traditional switched-capacitor (SC) technique, the SI technique has both pros and cons that are highlighted in the book. With the consideration of similarity and difference of SI and SC techniques, oversampling A/D converter architectures are tailored and optimized for SI design and implementation in the book. Switched-Current Design and Implementation of Oversampling A/D Converters emphasizes the practical aspects of SI circuits without tedious mathematical derivations, and is full of circuit design and implementation examples. There are more than 10 different chips included in the book, demonstrating the high-speed (over 100 MHz) and ultra-low-voltage (1.2 V) operation of SI circuits and systems in standard digital CMOS processes. Therefore, the book is of special value as a practical guide for designing SI circuits and SI oversampling A/D converters. Switched-Current Design and Implementation of Oversampling A/D Converters serves as an excellent reference for analog designers, especially A/D converter designers, and is of interest to digital designers for real-time signal processing who need A/D interfaces. The book may also be used as a text for advanced courses on the subject.

Buch. Condición: Neu. Neuware - Food security is defined as the ability of countries, regions, or households to meet their required levels of food consumption at all times. Food security is an important component of human welfare, and it can act as an indicator of a region's development. This book addresses the roles of trade, policy development, and economic cooperation in creating sustainable food security in the West African region. The largely micro-level analysis is conducted on empirical data from the household where decisions on production and consumption take place. Food security is discussed in terms of its component parts, namely: availability of food (production and trade), its accessibility (incomes and poverty status), and its utilisation (health and nutrition).

Buch. Condición: Neu. Neuware - Drying is traditionally defined as that unit operation which converts a liquid, solid or semi-solid feed material into a solid product of significantly lower moisture content. In most, although not all, cases it involves the application of thermal energy, which causes water to evaporate into the vapour phase. In practice, this definition encompasses a number of technologies which differ markedly in, for example, the manner in which energy is supplied to the foodstuff and in which product is transported through the dryer. Depending on the dryer type, the residence time may vary from a few seconds to several hours. Dryers designed to handle liquid feedstocks are naturally quite different from those intended to process moist solids. Even within these two broad categories, however, many distinct varieties of dryer have evolved to meet specific process ing needs. The dryer is frequently the last processing stage in the manufacture of a dehydrated food product. As such, it may not only bring about the desired reduction in moisture content but may also have a significant effect on a number of other properties, such as flavour, colour, texture, viability, and nutrient retention, for example. These properties, which are generally considered to affect the perceived quality of the end product, are often influenced by the temperature- moisture content-time profiles experienced by the foodstuff as it moves through the dryer. The underlying chemistry and physics are highly complex and, broadly speaking, only poorly understood.

Buch. Condición: Neu. Neuware - Information Systems and Data Compression presents a uniform approach and methodology for designing intelligent information systems. A framework for information concepts is introduced for various types of information systems such as communication systems, information storage systems and systems for simplifying structured information. The book introduces several new concepts and presents a novel interpretation of a wide range of topics in communications, information storage, and information compression. Numerous illustrations for designing information systems for compression of digital data and images are used throughout the book.

Taschenbuch. Condición: Neu. Neuware -The impetus for this book arose out of my previous book, The Evolution of Life Histories (Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory. However, as the book was concerned with the evolution of life histories and traits connected to this, the presence of quantitative genetic variation was an underlying theme throughout. Much of the focus was placed on optimality theory, for it is this approach that has proven to be extremely successful in the analysis of life history variation. But quantitative genetics cannot be ig nored, because there are some questions for which optimality approaches are inappropriate; for example, although optimality modeling can address the ques tion of the maintenance of phenotypic variation, it cannot say anything about genetic variation, on which further evolution clearly depends. The present book is, thus, a natural extension of the first. I have approached the problem not from the point of view of an animal or plant breeder but from that of one interested in understanding the evolution of quantitative traits in wild populations. The subject is large with a considerable body of theory: I generally present the assumptions underlying the analysis and the results, giving the relevant references for those interested in the intervening mathematics. My interest is in what quantitative genetics tells me about evolutionary processes; therefore, I have concentrated on areas of research most relevant to field studies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 512 pp. Englisch.

Buch. Condición: Neu. Neuware -As with the first edition this book includes chapters on established fish processes and new processes and allied issues. The first five chapters cover fish biochemistry affecting processing, curing, surimi and fish mince, chilling and freezing and canning. These established processes can still show innovations and improved theory although their mature status precludes major leaps in knowledge and technology. The four chapters concerned with new areas relevant to fish processing are directed at the increasing globalisation of the fish processing industry and the demands, from legislation and the consumer, for better quality, safer products. One chapter reviews the methods available to identify fish species in raw and processed products. The increased demand for fish products and the reduced catch of commercially-important species has lead to adulteration or substitu tion of these species with cheaper species. The ability to detect these practices has been based on some elegant analytical techniques in electrophoresis.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Buch. Condición: Neu. Neuware -The popularity of the 1973 fifth edition of The Technology of Cake Making has continued in many of the English-speaking countries throughout the world. This sixth edition has been comprehensively revised and brought up to date with new chapters on Cream, butter and milkfat products, Lactose, Yeast aeration, Emulsions and emulsifiers, Water activity and Reduced sugar Eggs and egg products, Baking fats, and lower fat goods. The chapters on Sugars, Chemical aeration, Nuts in confectionery, Chocolate, Pastries, Nutritional value and Packaging have been completely rewritten. The increased need for the continuous development of new products does not of necessity mean that new technology has to be constantly introduced. Many of the good old favourites may continue to be produced for many years and they form suitable 'bench marks' for new product development. The sixth edition introduces the use of relative density to replace specific volume as a measure of the amount of aeration in a cake batter (the use of relative density is in line with international agreement). Specific volume is kept as a measurement of baked product volume since the industry is comfortable with the concept that, subject to an upper limit, an increase in specific volume coincides with improvement in cake quality. 440 pp. Englisch.
