Taschenbuch. Condizione: Neu. Neuware -This book describes the design and internals of the MOSIXdistributed operating system. MOSIX, an acronym for Multicomputer Operating System for UNIX, integrates a cluster of loosely integrated computers into a virtual single-machine UNIX environment. The main property of MOSIX is the high degree of integration among the processors, which may include personal workstations and shared memory and non-shared memory multiprocessors, connected by fast communication links. This integration includes network transparency, cooperation between the processors to provide services across machine boundaries, support of dynamic configuration, and system-initiated load balancing by process migration. Another property of MOSIX is the ability to scale up the system configuration to encompass a large number of computers. The development of MOSIX was begun in 1981. The book is intended primarily for readers who are interested in distributed and multiprocessor systems. The reader is assumed to have some knowledge in programming and operating systems, preferably UNIX. Readers without this background will still benefit from thetechniques and algorithms discussed.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The papers contained in this volume were presented at theFourth Annual Symposium on Combinatorial Pattern Matchingheld in Padova, Italy, in June 1993.Combinatorial pattern matching addresses issues of searchingand matching of strings and more complicated patterns suchas trees, regular expressions, extended expressions, etc.The goal is to derive nontrivial combinatorial propertiesfor such structures and then to exploit these properties inorder to achieve superior performance for the correspondingcomputational problems. In recent years, a steady flow ofhigh-quality scientific studies of this subject has changeda sparse set of isolated results into a full-fledged area ofalgorithmics.The area is expected to grow even further due to theincreasing demand for speedand efficiency that comesespecially from molecular biology and the Genome projectbut also from other diverse areas such as informationretrieval, pattern recognition, compilers, data compressionand program analysis.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Condizione: Neu. Neuware -This is a text for a one-quarter or one-semester course in probability, aimed at students who have done a year of calculus. The book is organised so a student can learn the fundamental ideas of probability from the first three chapters without reliance on calculus. Later chapters develop these ideas further using calculus tools. The book contains more than the usual number of examples worked out in detail.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 576 pp. Englisch.

Buch. Condizione: Neu. Neuware -Mathematics is playing an ever more important role in the physical and biological sciences, provoking a blurring of boundaries between scientific disciplines and a resurgence of interest in the modern as weil as the clas sical techniques of applied mathematics. This renewal of interest, bothin research and teaching, has led to the establishment of the series: Texts in Applied Mathematics (TAM). The development of new courses is a natural consequence of a high Ievel of excitement on the research frontier as newer techniques, such as numerical and symbolic computer systems, dynamical systems, and chaos, mix with and reinforce the traditional methods of applied mathematics. Thus, the purpose of this textbook series is to meet the current and future needs of these advances and encourage the teaching of new courses. TAM will publish textbooks suitable for use in advanced undergraduate and beginning graduate courses, and will complement the Applied Mathematical Seiences (AMS) series, whichwill focus on advanced textbooks and research Ievel monographs. Preface This book is based on a one-term coursein fluid mechanics originally taught in the Department of Mathematics of the U niversity of California, Berkeley, during the spring of 1978. The goal of the course was not to provide an exhaustive account of fluid mechanics, nor to assess the engineering value of various approximation procedures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.

Buch. Condizione: Neu. Neuware - This book examines the economics of an industry that has become a critical component of modern life - the electric utility industry. The public nature of electricity has affected the development of the industry, both private and public. While this book focuses on private utilities, it recognizes the potential for a resurgence of public ownership. The objective of the book is to examine factors that will affect the evolution of markets for power. Of critical importance is the role of information, which is required for making and evaluating decisions in power markets. This book demonstrates that utilities can exploit information as a source of market power, impeding the development of more competitive and efficient markets. To a large extent the source of the utilities' market power is the ability to specify computer models used in the planning, pricing and operation of markets for electricity. A number of concepts related to the use and control of information and models are developed in this book.

Buch. Condizione: Neu. Neuware -Leon N. Moses In June 1991, the Transportation Center at Northwestern University sponsored Hazmat Transport '91: A National Conference on the Transportation of Hazardous Materials and Wastes. The faculty associated with the center were aware that there had been many professional, industrial and government conferences and meetings on the subject. However, they believed that the unique capacity of the Transportation Center to bring together leaders from industry and government, as well as leading scholars from economics, law, engineering, psychology and sociology who have done research on the problems associated with the transportation of hazardous materials and wastes (hazmats), could produce a set of integrated insights and understandings that would go well beyond those of previous conferences. The papers that make up this volume were all delivered at Hazmat Transport '91. From a legislative point of view, they tend to deal with issues associated with the Hazardous Materials Transportation Act of 1975 (HMTA), the original act passed to regulate the transportation of hazardous materials, and the Hazardous Materials Transportation Uniform Safety Act of 1990 (HMTVSA). There were talks and papers presented at the conference that focused on other recent legislation and transportation issues with which HMTUSA does not deal. The conference proceedings volume also had discussions and papers on significant managerial and regulatory issues that could not be included in this volume because of constraints on its size. Therefore, this essay is made up of three parts.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Buch. Condizione: Neu. Neuware -Previously published in hardback and now made available in paperback, this ground-breaking book is a must for all interested in butterflies, whether as conservation biologist, amateur or professional entomologist or as a student studying the phenomenon of butterfly populations as part of a number of biology, ecology or conservation courses.Recently, many British butterflies have suffered severe declines whole others have flourished and expanded in range. This is the first book to describe the results from a British scheme to monitor butterflies during this period of change. The Monitoring Scheme, initiated in 1976 by the senior author is based on frequent counts at some 90 sites throughout Britain. The combined efforts of both amateurs and professionals have thus produced a dataset with no equivalent elsewhere in the world. The book therefore provides a unique perspective on trends in numbers, extinction and foundation of populations; flight periods, local distributions, migration and other aspects of population ecology. Practical problems encountered during the conservation of butterflies of individual sites are outlined. The relevance of this monitoring for an understanding of the effects of the weather - climatic warming - is described.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -''Intended mainly for physicists and mathematicians.its high quality will definitely attract a wider audience.'' ---Computational Mathematics and Mathematical Physics This work acquaints the physicist with the mathematical principles of algebraic topology, group theory, and differential geometry, as applicable to research in field theory and the theory of condensed matter. Emphasis is placed on the topological structure of monopole and instanton solution to the Yang-Mills equations, the description of phases in superfluid 3He, and the topology of singular solutions in 3He and liquid crystals.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 376 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -One of the liveliest areas of research in the social sciences is reading. Scholarly activity is currently proceeding along a number of different disciplinary lines, addressing a multitude of questions and issues about reading. A short list of disciplines involved in the study of reading would include linguistics, psychology, education, history, and gerontology. Among the important questions being ad dressed are some long-standing concerns: How are reading skills acquired What are the basic components of reading skill How do skilled readers differ from less skilled ones What are the best ways to approach instruction for different groups of readers-young beginning readers, poor readers with learning problems, and teenage and adult illiterates How can reading skill best be measured-what standardized instruments and observational techniques are most useful The large volume of textbooks and scholarly books that issue forth each year is clear evidence of the dynamic nature of the field. The purpose of this volume is to survey some of the best work going on in the field today and reflect what we know about reading as it unfolds across the life span. Reading is clearly an activity that spans each of our lives. Yet most accounts of it focus on some narrow period of development and fail to consider the range of questions that serious scholarship needs to address for us to have a richer under standing of reading. The book is divided into four parts.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Englisch.

Buch. Condizione: Neu. Neuware - This volume illuminates the multidisciplinary character of photosynthesis, which spans (bio)physics to agronomy. The book will help provide students with the necessary conceptual outlook for integrating information from the bioenergetic and enzymatic angles, obtained at the molecular l4vel, with the physiology of chloroplasts, leaves and eventually crops. It therefore serves the larger interests of both students and researchers in the areas of agriculture, biotechnology, biochemistry, biophysics, plant physiology, and molecular biology, who are engaged in studying not only the basic aspects of photosynthesis, a major process determining biomass production, but also its relationship to plant productivity. The possibility of using the information in this book to improve biomass and grain yield is something that no one can ignore.

Buch. Condizione: Neu. Neuware - The text Modern Electrochemistry (authored by J. O'M. Bockris and A. K. N. Reddy and published by Plenum Press in 1970) was written between 1967 and 1969. The concept for it arose in 1962 in the Energy Conversion Center at the University of Pennsylvania, and it was intended to act as a base for interdisciplinary students and mature scientists~hemists, physicists, biologists, metallurgists, and engineers-who wanted to know about electrochemical energy conversion and storage. In writing the book, the stress, therefore, was placed above all on lucidity in teaching physical electrochemistry from the beginning. Although this fundamentally undergraduate text continues to find purchasers 20 years after its birth, it has long been clear that a modernized edition should be written, and the plans to do so were the origin of the present book. However, if a new Bockris and Reddy was to be prepared and include the advances of the last 20 years, with the same degree of lucidity as characterized thefirst one, the depth of the development would have to be well short of that needed by professional electrochemists.

Buch. Condizione: Neu. Neuware -This book provides the background, physical instrumentation and geological aspects behind any study of the magnetic anisotropy of a rock in a comprehensive and practical way. After studying this book, readers in the geosciences will be encouraged to use this simple, rapid and inexpensive technique in their studies of rocks.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 230 pp. Englisch.

Buch. Condizione: Neu. Neuware -There are many different types of organisms in the world: they differ in size, physiology, appearance, and life history. The challenge for evolutionary biology is to explain how such diversity arises. The Evolution of Life Histories does this by showing that natural selection is the principal underlying force molding life history variation. The book describes in particular the ways in which variation can be analyzed and predicted. It covers both the genetic and optimization approaches to life history analysis and gives an overview of the general framework of life history theory and the mathematical tools by which predictions can be made and tested. Factors affecting the age schedule of birth and death and the costs of reproduction are discussed. The Evolution of Life Histories concentrates on those theoretical developments that have been tested experimentally. It will interest both students and professionals in evolution, evolutionary ecology, mathematical and theoretical biology, and zoology and entomology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 548 pp. Englisch.

Buch. Condizione: Neu. Neuware -This volume attemptsto provide the formulation scientist with casehistories involving the use of therapeutic proteins and peptides that have been mar keted or are under clinical testing. In previous volumes of this series,funda mental theories and principles ofprotein characterization and stability were presented in depth by researchers in their fieldsofexpertise. The way from theory to practice isnot alwaysobvious and straightforward. There isa need for practical examples of how the principles and theories are put into use, specificallyin the development of a pharmaceutical product. It is our hope that this volume will fulfillsuch a need. Itisnot asimple task to choose a panel ofproteinsand peptides from the over 200 agents in human clinical trials. We have tried to collect a wide representation of molecules of different sizes-from 10 amino acids (Leu prolide) to 1020 amino acids (Muromonab CD3). The examples include agents derived from various sources including monoclonal antibodies (Mur omonab CD3), recombinant DNA (human and bovine growth hormones), natural source (fibrolase), and chemical synthesis (Leuprolide). Clearly this list is not intended to be encyclopedic. It isthe first time a collection of this sort has been made accessibleto the formulation scientists involved in devel oping protein and peptide products. Although each chapter in this volume focuses primarily on the charac terization and stability of a specific molecule, each has unique aspects.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Buch. Condizione: Neu. Neuware -Plant disease is one of the greatest causes of economic losses of crops throughout the world. Every year, billions of dollars are spent on chemical control measures, but there is an increasing awareness that alternatives to these chemical control measures may be becoming more viable. This work explores the international impact of plant disease on man and how this is measured and diagnosed, discusses epidemiology and the genetics of host-parasite relations and looks at the range of defensive tactics currently available and those under development, in particular those which are more environmentally acceptable than many in widespread use now.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 370 pp. Englisch.

Buch. Condizione: Neu. Neuware -The thirty-one papers collected in this volume represent most of the arti cles that I have published in the philosophy of science and related founda tional areas of science since 1970. The present volume is a natural succes sor to Studies in the Methodology and Foundations of Science, a collection of my articles published in 1969 by Reidel (now a part of Kluwer). The articles are arranged under five main headings. Part I contains six articles on general methodology. The topics range from formal methods to the plurality of science. Part II contains six articles on causality and explanation. The emphasis is almost entirely on probabilistic approaches. Part III contains six articles on probability and measurement. The impor tance of representation theorems for both probability and measurement is stressed. Part IV contains five articles on the foundations of physics. The first three articles are concerned with action at a distance and space and time, the last two with quantum mechanics. Part V contains eight articles on the foundations of psychology. This is the longest part and the articles reflect my continuing strong interest in the nature of learning and perception. Within each part the articles are arranged chronologically. I turn now to a more detailed overview of the content. The first article of Part I concerns the role of formal methods in the philosophy of science. Here I discuss what is the new role for formal methods now that the imperialism of logical positivism has disappeared.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 530 pp. Englisch.

Buch. Condizione: Neu. Neuware - High-Performance CMOS Continuous-Time Filters is devoted to the design of CMOS continuous-time filters. CMOS is employed because the most complex integrated circuits have been realized with this technology for two decades. The most important advantages and drawbacks of continuous-time filters are clearly shown. The transfer function is one of the most important filter parameters but several others (like intermodulation distortion, power-supply rejection ratio, noise level and dynamic range) are fundamental in the design of high-performance systems. Special attention is paid to the practical aspects of the design, which shows the difference between an academic design and an industrial design. A clear understanding of the behavior of the circuits and techniques is preferred over complex equations or interpretation of simulated results. Step-by-step design procedures are very often used to clarify the use of the techniques and topologies. The organization of this text is hierarchical, starting with the design consideration of the basic building blocks and ending with the design of several high-performance continuous-time filters. Most of the circuits have been fabricated, theoretically analyzed and simulated, and silicon measurement results are compared with each other. High-Performance CMOS Continuous-Time Filters can be used as a text book for senior or graduate courses on this topic and can also be useful for industrial engineers as a reference book.

Buch. Condizione: Neu. Neuware - Due to the progress in VLSI technology, integrated circuit chips are now available that allow video/image signal processing to be performed with a single VLSI chip or small sets of VLSI chips. Recent standardization on bandwidth compression schemes for still images (JPEG) and motion pictures (H.261, R723, MPEG) also encourage the development of VLSI video/image processors for cost-effective solutions. Furthermore, recent trends suggest that the standardization on HDTB bandwidth compression for broadcasting and storage purposes is just around the corner. In terms of device technology, however, the progress achieved in increasing speed is not as high as that achieved by integration. The development of high speed systems is due to architectural effort, rather than device technology. This is why high speed architectures, such as those for special wired logic realization and for multi-processors are of great interest to VLSI system designers. VLSI Video/Image Signal Processing is an edited volume of original research comprising invited contributions by leading researchers.

Buch. Condizione: Neu. Neuware - Instruction-Level Parallelism presents a collection of papers that attempts to capture the most significant work that took place during the 1980s in the area of instruction-level (ILP) parallel processing. The papers in this book discuss both compiler techniques and actual implementation experience on very long instruction word (VLIW) and superscalar architectures.

Buch. Condizione: Neu. Neuware - To produce a comprehensive overview of macrophages and related cell types in a short review volume is an impossible task. When I selected the topics to be included, some equally important areas were omitted by necessity, and for this I apologize. My choices have been somewhat eclectic, touching subjects of personal interest (such as osteoclast biology and macrophage electrophysiology) or of current fashion (apopto sis, antigen processing, cell adhesion molecules). The book has also had to encompass areas of a more general flavor to provide balance for the general reader (such as reviews of macrophage development, heterogeneity, and function, and of the surface molecules expressed by macrophages). I thank all the authors for their prompt sub missions; all have been of high quality, and my editorial tasks, thankfully, have been minimal. Michael A.

Buch. Condizione: Neu. Neuware -Boron has all the best tunes. That may well be the first impression of the Group 13 elements. The chemical literature fosters the impression not only in the primary journals, but also in asteady outflowofbooks focussing more or less closely on boron and its compounds. The same preoccupation with boron is apparent in the coverage received by the Group 13 elements in the comprehensive and regularly updated volume of the Gmelin Handbook. Yet such an imbalance cannot be explained by any inherent lack ofvariety, interest or consequence in the 'heavier elements. Aluminium is the most abundant metal in the earth's crust; in the industrialised world the metal is second only to iron in its usage, and its compounds can justifiably be said to touch our lives daily - to the potential detriment of those and other lives, some would argue. From being chemical curios, gallium and indium have now gained considerably prominence as sources of compound semiconductors like gallium arsenide and indium antimonide. Nor is there any want ofincident in the chemistriesofthe heavier Group 13 elements. In their redox, coordination and structural properties, there is to be found music indeed, notable not always for its harmony but invariably for its richness and variety. Thisbook seeks to redress the balance with a definitive, wide-rangingand up-to-date review of the chemistry of the Group 13 metals aluminium, gallium, indium and thallium.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 544 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Stochastic processes with independent increments on a groupare generalized to the concept of 'white noise' on a Hopfalgebra or bialgebra. The main purpose of the book is thecharacterization of these processes as solutions of quantumstochastic differential equations in the sense of R.L.Hudsonand K.R. Parthasarathy. The notes are a contributionto quantum probability but they are also related toclassical probability, quantum groups, and operatoralgebras. The Az ma martingales appear as examples of whitenoise on a Hopf algebra which is a deformation of theHeisenberg group.The book will be of interest to probabilists and quantumprobabilists. Specialists in algebraic structures who arecurious about the role of their concepts in probablilitytheory as well as quantum theory may find the bookinteresting. The reader should havesome knowledge offunctional analysis, operator algebras, and probabilitytheory. 156 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Given a familiar object extracted from its surroundings, wehumans have little difficulty in recognizing it irrespectiveof its size, position and orientation in our field of view.Changes in lighting and the effects of perspective also poseno problems. How do we achieve this, and more importantly,how can we get a computer to do this One very promisingapproach is to find mathematical functions of an object'simage, or of an object's 3D description, that are invariantto the transformations caused by the object's motion.This book is devoted to the theory and practice of suchinvariant image features, so-called image invariants, forplanar objects. It gives a comprehensive summary of thefield, discussing methods for recognizing both occluded andpartially occluded objects, and also contains a definitivetreatmentof moment invariants and a tutorial introductionto algebraic invariants, which are fundamental to affinemoment invariants and to many projective invariants.A number of novel invariant functions are presented and theresults of numerous experiments investigating the stabilityof new and old invariants are discussed. The main conclusionis that moment invariants are very effective, both forpartially occluded objects and for recognizing objects ingrey-level images. 196 pp. Englisch.
