Taschenbuch. Condición: Neu. Neuware -The theme of the monograph is an interplay between dynamical systems and group theory. The authors formalize and study 'cyclic renormalization', a phenomenon which appears naturally for some interval dynamical systems. A possibly infinite hierarchy of such renormalizations is naturally represented by a rooted tree, together with a 'spherically transitive' automorphism; the infinite case corresponds to maps with an invariant Cantor set, a class of particular interest for its relevance to the description of the transition to chaos and of the Mandelbrot set. The normal subgroup structure of the automorphism group of such 'spherically homogeneous' rooted trees is investigated in some detail. This work will be of interest to researchers in both dynamical systems and group theory. 196 pp. Englisch.

Buch. Condición: Neu. Neuware -This is a textbook suitable for a year-long course in analysis at the ad vanced undergraduate or possibly beginning-graduate level. It is intended for students with a strong background in calculus and linear algebra, and a strong motivation to learn mathematics for its own sake. At this stage of their education, such students are generally given a course in abstract algebra, and a course in analysis, which give the fundamentals of these two areas, as mathematicians today conceive them. Mathematics is now a subject splintered into many specialties and sub specialties, but most of it can be placed roughly into three categories: al gebra, geometry, and analysis. In fact, almost all mathematics done today is a mixture of algebra, geometry and analysis, and some of the most in teresting results are obtained by the application of analysis to algebra, say, or geometry to analysis, in a fresh and surprising way. What then do these categories signify Algebra is the mathematics that arises from the ancient experiences of addition and multiplication of whole numbers; it deals with the finite and discrete. Geometry is the mathematics that grows out of spatial experience; it is concerned with shape and form, and with measur ing, where algebra deals with counting.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 354 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Meat and Meat Products integrates the fundamental disciplines of food science, such as chemistry and microbiology, with processing technology and product - related aspects such as criteria for acceptability. The book provides thoroughly integrated and up-to-date coverage of this important food group and by careful use of learning objectives, tables, figures, boxes and exercises, guides the professional and student alike through its user friendly and clear format.The book includes details of conversion of muscle into meat, uncooked, comminuted and re-formed meat products, cured and cooked meats and meat products, fermented meats and frozen and dried meats and meat products. The study of meat and meat products is a major part of most food science and technology courses, and is therefore invaluable to undergraduate students studying these disciplines and to those taking more specialized MSc or other postgraduate courses.As the book provides thorough coverage of all industrial aspects, including control points (HACCP), it is also of great use to food industry employees involved in product development, production management and quality assurance, especially those studying for professional qualifications. Academics involved in teaching elements of this subject and personnel involved in a regulatory capacity should also find this book ideal for their use.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 444 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware - Commutative Algebra is best understood with knowledge of the geometric ideas that have played a great role in its formation, in short, with a view towards algebraic geometry. The author presents a comprehensive view of commutative algebra, from basics, such as localization and primary decomposition, through dimension theory, differentials, homological methods, free resolutions and duality, emphasizing the origins of the ideas and their connections with other parts of mathematics. Many exercises illustrate and sharpen the theory and extended exercises give the reader an active part in complementing the material presented in the text. One novel feature is a chapter devoted to a quick but thorough treatment of Grobner basis theory and the constructive methods in commutative algebra and algebraic geometry that flow from it. Applications of the theory and even suggestions for computer algebra projects are included. This book will appeal to readers from beginners to advanced students of commutative algebra or algebraic geometry. To help beginners, the essential ideals from algebraic geometry are treated from scratch. Appendices on homological algebra, multilinear algebra and several other useful topics help to make the book relatively self- contained. Novel results and presentations are scattered throughout the text.

Buch. Condición: Neu. Neuware -X-ray crystallography provides us with the most accurate picture we can get of atomic and molecular structures in crystals. It provides a hard bedrock of structural results in chemistry and in mineralogy. In biology, where the structures are not fully crystalline, it can still provide valuable results and, indeed, the impact here has been revolutionary. It is still an immense field for young workers, and no doubt will provide yet more striking developments of a major character. It does, however, require a wide range of intellectual application, and a considerable ability in many fields. This book will provide much help. It is a very straightforward and thorough guide to every aspect of the subject. The authors are ex perienced both as research workers and as teachers of standing, and this is shown in their clarity of exposition. There are plenty of illustrations and worked examples to aid the student to obtain a real grasp of the subject. The practical side is encouraged by the very clarity of the theory.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 616 pp. Englisch.

Buch. Condición: Neu. Neuware -Although the calculus of variations has ancient origins in questions of Ar istotle and Zenodoros, its mathematical principles first emerged in the post calculus investigations of Newton, the Bernoullis, Euler, and Lagrange. Its results now supply fundamental tools of exploration to both mathematicians and those in the applied sciences. (Indeed, the macroscopic statements ob tained through variational principles may provide the only valid mathemati cal formulations of many physical laws. ) Because of its classical origins, variational calculus retains the spirit of natural philosophy common to most mathematical investigations prior to this century. The original applications, including the Bernoulli problem of finding the brachistochrone, require opti mizing (maximizing or minimizing) the mass, force, time, or energy of some physical system under various constraints. The solutions to these problems satisfy related differential equations discovered by Euler and Lagrange, and the variational principles of mechanics (especially that of Hamilton from the last century) show the importance of also considering solutions that just provide stationary behavior for some measure of performance of the system. However, many recent applications do involve optimization, in particular, those concerned with problems in optimal control. Optimal control is the rapidly expanding field developed during the last half-century to analyze optimal behavior of a constrained process that evolves in time according to prescribed laws. Its applications now embrace a variety of new disciplines, including economics and production planning.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 482 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This book is an introduction to hyperbolic and differential geometry that provides material in the early chapters that can serve as a textbook for a standard upper division course on hyperbolic geometry. For that material, the students need to be familiar with calculus and linear algebra and willing to accept one advanced theorem from analysis without proof. The book goes well beyond the standard course in later chapters, and there is enough material for an honors course, or for supplementary reading. Indeed, parts of the book have been used for both kinds of courses. Even some of what is in the early chapters would surely not be nec essary for a standard course. For example, detailed proofs are given of the Jordan Curve Theorem for Polygons and of the decomposability of poly gons into triangles, These proofs are included for the sake of completeness, but the results themselves are so believable that most students should skip the proofs on a first reading. The axioms used are modern in character and more 'user friendly' than the traditional ones. The familiar real number system is used as an in gredient rather than appearing as a result of the axioms. However, it should not be thought that the geometric treatment is in terms of models: this is an axiomatic approach that is just more convenient than the traditional ones. 304 pp. Englisch.

Buch. Condición: Neu. Neuware - It is said that business re-engineering is part of our transition to a post-industrial society. The purpose of this book is to present an approach to how to reorganize businesses using the discipline of software engineering as a guiding paradigm. The author's thesis is that software engineering provides the necessary analytical expertise for defining business processes and the tools to transform process descriptions to support systems. The author begins by introducing the concepts and needs for business reengineering and principles and practice of software engineering. He then shows how by concentrating on processes, a business can define the information base required and how it is to be constructed. As a result, any manager or technically-minded person will learn how to implement the reengineering of a business.

Buch. Condición: Neu. Neuware -Branch-and-bound search has been known for a long time and has been widely used in solving a variety of problems in computer-aided design (CAD) and many important optimization problems.In many applications, the classic branch-and-bound search methods perform duplications of computations, or rely on the search decision trees which keep track of the branch-and-bound search processes. In CAD and many other technical fields, the computational cost of constructing branch-and-bound search decision trees in solving large scale problems is prohibitive and duplications of computations are intolerable. Efficient branch-and-bound methods are needed to deal with today's computational challenges. Efficient branch-and-bound methods must not duplicate computations.Efficient Branch and Bound Search with Application to Computer-Aided Design describes an efficient branch-and-bound method for logic justification, which is fundamental to automatic test pattern generation (ATPG), redundancy identification, logic synthesis, minimization, verification, and other problems in CAD. The method is called justification equivalence, based on the observation that justification processes may share identical subsequent search decision sequences. With justification equivalence, duplication of computations is avoided in the dynamic branch-and-bound search process without using search decision trees.Efficient Branch and Bound Search with Application to Computer-Aided Design consists of two parts. The first part, containing the first three chapters, provides the theoretical work. The second part deals with applications, particularly ATPG for sequential circuits.This book is particularly useful to readers who are interested in the design and test of digital circuits.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Buch. Condición: Neu. Neuware -Introduction In the present essay, we attempt to convey some idea of the skeleton of topology, and of various topological concepts. It must be said at once that, apart from the necessary minimum, the subject-matter of this survey does not indude that subdiscipline known as 'general topology' - the theory of general spaces and maps considered in the context of set theory and general category theory. (Doubtless this subject will be surveyed in detail by others. ) With this qualification, it may be daimed that the 'topology' dealt with in the present survey is that mathematieal subject whieh in the late 19th century was called Analysis Situs, and at various later periods separated out into various subdisciplines: 'Combinatorial topology', 'Algebraic topology', 'Differential (or smooth) topology', 'Homotopy theory', 'Geometrie topology'. With the growth, over a long period of time, in applications of topology to other areas of mathematics, the following further subdisciplines crystallizedout: the global calculus of variations, global geometry, the topology of Lie groups and homogeneous spaces, the topology of complex manifolds and alge braic varieties, the qualitative (topologieal) theory of dynamical systems and foliations, the topology of elliptic and hyperbolic partial differential equations. Finally, in the 1970s and 80s, a whole complex of applications of topologie al methods was made to problems of modern physiesj in fact in several instances it would have been impossible to understand the essence of the real physical phenomena in question without the aid of concepts from topology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Buch. Condición: Neu. Neuware -As was the case with Charles Ross's Packaging of Pharmaceuticals published by the UK Institute of Packaging in 1975 it is assumed that the reader of this book already has a broad understanding of the basics of packaging. If not the Packaging Users Handbook and the Handbook of Food Packaging are recommended. The packaging needs of pharmaceuticals are different in degree only from those of other perishable products such as processed foods. Because the required action of a medication can be nullified by any deterioration in its active principles the protection required from its packaging is at least an order of magnitude greater than that needed by foods for example. Functional efficiency is therefore of prime importance. Conversely the need for the packaging to 'sell' the medication is much less, hence the graphics required need only provide the right 'image' for the product when presented for use in hospital or surgery. Even when on sale at the pharmacy the 'appeal' required is that of providing hygiene and confidence more than anything else. Thus, the textual requirements are paramount including traceability (batch numbers, date-coding etc) in case of recall; while striking appearance to attract customer attention is in lower key. And with the increase in malicious tampering nowadays recall is more frequent.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

It consolidates existing data on the current state of the environment and economy of the region, develops a system of indicators of sustainable developments, makes recommendations on additional components to the existing monitoring system and considers a legal framework and instrument for its implementation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Buch. Condición: Neu. Neuware -This is a book about the simultaneous location, production and distri bution decisions of a firm entering a competitive market whose spatial nature is describable by a network in which the market either achieves an equilibrium or is equilibrium tending. As such, the problem is of clear theoretical and practical importance, for it is a rather general version of the problem faced by real firms every day in deciding where to locate. Further, the timeliness of this subject manifests itself in the growing excitement and interest found both in the research/academic communities and in the practitioner/private industry communities for more comprehensive approaches to competitive facility location analy sis and equilibrium modeling of networks. The desire both for new conceptual approaches yielding enhanced insights and for practical methodologies to capture these insights drives this interest. While nor mative, deterministic facility location modeling techniques currently provide valuable input into the location decision-making process, re searchers and practitioners alike have realized the vast and relatively untapped potential of more advanced location decision making tech niques. In this book, we develop what we believe represents a major new line of research in the field of competitive facility location analysis; namely, equilibrium facility location modeling. In particular, this book offers a number of innovations in the mathe matical analysis and computation of solutions to location models which we have pioneered and which are collected under a single cover for the first time.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condición: Neu. Neuware -Since 1992 Finsler geometry, Lagrange geometry and their applications to physics and biology, have been intensive1y studied in the context of a 5-year program called 'Memorandum ofUnderstanding', between the University of Alberta and 'AL.1. CUZA' University in lasi, Romania. The conference, whose proceedings appear in this collection, belongs to that program and aims to provide a forum for an exchange of ideas and information on recent advances in this field. Besides the Canadian and Romanian researchers involved, the conference benefited from the participation of many specialists from Greece, Hungary and Japan. This proceedings is the second publication of our study group. The first was Lagrange Geometry. Finsler spaces and Noise Applied in Biology and Physics (1]. Lagrange geometry, which is concerned with regular Lagrangians not necessarily homogeneous with respect to the rate (i.e. velocities or production) variables, naturalIy extends Finsler geometry to alIow the study of, for example, metrical structures (i.e. energies) which are not homogeneous in these rates. Most Lagrangians arising in physics falI into this class, for example. Lagrange geometry and its applications in general relativity, unified field theories and re1ativistic optics has been developed mainly by R. Miron and his students and collaborators in Romania, while P. Antonelli and his associates have developed models in ecology, development and evolution and have rigorously laid the foundations ofFinsler diffusion theory [1] .Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 298 pp. Englisch.

Buch. Condición: Neu. Neuware -Computational Psycholinguistics: An Interdisciplinary Approach to the Study of Language investigates the architecture and mechanisms which underlie the human capacity to process language. It is the first such study to integrate modern syntactic theory, cross-linguistic psychological evidence, and modern computational techniques in constructing a model of the human sentence processing mechanism.The monograph follows the rationalist tradition, arguing the central role of modularity and universal grammar in a theory of human linguistic performance. It refines the notion of `modularity of mind', and presents a distributed model of syntactic processing which consists of modules aligned with the various informational `types' associated with modern linguistic theories. By considering psycholinguistic evidence from a range of languages, a small number of processing principles are motivated and are demonstrated to hold universally. It is also argued that the behavior of modules, and the strategies operative within them, can be derived from an overarching `Principle of Incremental Comprehension'.Audience: The book is recommended to all linguists, psycholinguists, computational linguists, and others interested in a unified and interdisciplinary study of the human language faculty.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Buch. Condición: Neu. Neuware -Milk and dairy products are a major part of the human diet in many countries. It is not surprising therefore that considerable attention is paid to obtaining the best possible quality of milk by improving the yield, compositional quality and hygienic quality, and minimizing the level of contaminants at all stages of milk production. This book provides easily understood background knowledge of milk quality problems. It identifies the quality parameters of significance, and explains what they are, why they are important and how they are measured. Practical help is given for the sampling and testing of milk. Most important of all, the value of good quality milk and how it can be produced and maintained are stressed. This volume is essential reading for dairy scientists and technologists, particularly microbiologists, food processors, quality control personnel, nutritionists and regulatory officials. It will also be an invaluable source of reference for practitioners and researchers in dairy farming and veterinary science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 184 pp. Englisch.

Buch. Condición: Neu. Neuware -The evidence that omega-3 fatty acids are essential for human development and most helpful to achieve good health throughout life is clearly documented by Dr. Joyce Nettleton in her new book Omega-3 Fatty Acids and Health. Omega 3 fatty acids are produced by the plants of the land and sea. The tissues of the body require the omega-3 fatty acids for their proper functioning just as they also need the omega-6 essential fatty acids. It is probable in man's evolutionary development that there has always been the proper balance between these two groups of essential fatty acids, but in the modern era with the provision of inexpensive vegetable oils it is possible that the pendulum for increased dietary omega-6 fatty acids in the form of linoleic acid has swung too far and the intake ofomega-3 fatty acids has actualIy declined. In particular, the 22 carbon omega 3 fatty acid, docosahexaenoic acid, which has six double bonds, is important in the membranes of brain cells, heart muscle cells, the rods and cones of the retina and spermatozoa. Docosahexaenoic acid is found only in foods such as fish and other sea life, having been synthesized by the phytoplankton of the waters. An outright deficiency of omega-3 fatty acids has led to a number of distur bances in animals and human infants such as impaired vision, abnormalities of the electroretinogram, of the eye and various behavioral aberrations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Buch. Condición: Neu. Neuware -Food packaging materials have traditionally been chosen to avoid unwanted interactions with the food. During the past two decades a wide variety of packaging materials have been devised or developed to interact with the food. These packaging materials, which are designed to perform some desired role other than to provide an inert barrier to outside influences, are termed 'active packaging'. The benefits of active packaging are based on both chemical and physical effects. Active packaging concepts have often been presented to the food industry with few supporting results of background research. This manner of introduction has led to substantial uncertainty by potential users because claims have sometimes been based on extrapolation from what little proven information is available. The forms of active packaging have been chosen to respond to various food properties which are often unrelated to one another. For instance many packaging requirements for post harvest horticultural produce are quite different from those for most processed foods. The object of this book is to introduce and consolidate information upon which active packaging concepts are based. Scientists, technologists, students and regulators will find here the basis of those active packaging materials, which are either commercial or proposed. The book should assist the inquirer to understand how other concepts might be applied or where they should be rejected.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condición: Neu. Neuware -This book is an outgrowth of ideas originating from 1. Kluvanek. Unfortunately, Professor Kluvanek did not live to contribute to the project of writing up in a systematic form, the circle of ideas to which the present work is devoted. It is more than likely that with his input, the approach and areas of emphasis of the resulting exposition would have been quite different from what we have here. Nevertheless, the stamp of Kluvanek's thought and philosophy (but not necessarily his approval) abounds throughout this book. Although the title gives no indication, integration theory in vector spaces is a cen tral topic of this work. However, the various notions of integration developed here are intimately connected with a specific application-the representation of evolutions by func tional integrals. The representation of a perturbation to the heat semigroup in terms of Wiener measure is known as the Feynman-Kac formula, but the term has a wider meaning in the present work. Traditionally, such representations have been used to obtain analytic information about perturbations to free evolutions as an alternative to arguments with a more operator-theoretic flavour. No applications of this type are given here. It is an un derlying assumption of the presentation of this material that representations of the nature of the Feynman-Kac formula are worth obtaining, and in the process of obtaining them, we may be led to new, possibly fertile mathematical structures-a view largely motivated by the pervasive use of path integrals in quantum physics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -It is the aim of this study to present a framework for the design of technical systems. This can be achieved through a general Design Science, a knowledge system in which products are seen as objects to be developed within engineering design processes. The authors have developed this design science from a division of the knowledge system along two axes. One deals with knowledge about technical systems and design processes while the other presents descriptive statements. Relationships among the various sections of the knowledge system are made clear. Well-known insights into engineering design, the process, its management and its products are placed into new contexts. Particular attention is given to various areas of applicability. Widespread use throughout is made of easily assimilated diagrams and models.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.
