Buch. Condición: Neu. Neuware -1. 1 Typical Problems of Data Analysis Every branch of experimental science, after passing through an early stage of qualitative description, concerns itself with quantitative studies of the phe nomena of interest, i. e. , measurements. In addition to designing and carrying out the experiment, an importal1t task is the accurate evaluation and complete exploitation of the data obtained. Let us list a few typical problems. 1. A study is made of the weight of laboratory animals under the influence of various drugs. After the application of drug A to 25 animals, an average increase of 5 % is observed. Drug B, used on 10 animals, yields a 3 % increase. Is drug A more effective The averages 5 % and 3 % give practically no answer to this question, since the lower value may have been caused by a single animal that lost weight for some unrelated reason. One must therefore study the distribution of individual weights and their spread around the average value. Moreover, one has to decide whether the number of test animals used will enable one to differentiate with a certain accuracy between the effects of the two drugs. 2. In experiments on crystal growth it is essential to maintain exactly the ratios of the different components. From a total of 500 crystals, a sample of 20 is selected and analyzed.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 692 pp. Englisch.

Buch. Condición: Neu. Neuware -'Here's a gem of a book.all peppered with delightful notes from science fiction films, novels, and comics. I can't turn a page without finding a jewel.' Clifford Stoll, University of California, Berkeley, author of The Cuckoo's Egg 'The research that has gone into this book is impressive.' Nature 'For professional physicists much of the value lies in the extensive technical appendices and footnotes, and the exhaustive list of references. But if, like me, you are a child at heart, the real fun lies in the zany stories and wild speculations.' Physics World Time Machines explores the idea of time travel from the first account in English literature to the latest theories of physicists such as Kip Thorne and Igor Novikov. This very readable work covers a variety of topics including the history of time travel in fiction; the fundamental scientific concepts of time, spacetime, and the fourth dimension; the speculations of Einstein, Richard Feynman, Kurt Goedel, and others; time travel paradoxes, and much more.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 668 pp. Englisch.

Buch. Condición: Neu. Neuware -The last treatise on the theory of determinants, by T. Muir, revised and enlarged by W. H. Metzler, was published by Dover Publications Inc. in 1960. It is an unabridged and corrected republication of the edition ori- nally published by Longman, Green and Co. in 1933 and contains a preface by Metzler dated 1928. The Table of Contents of this treatise is given in Appendix 13. A small number of other books devoted entirely to determinants have been published in English, but they contain little if anything of importance that was not known to Muir and Metzler. A few have appeared in German and Japanese. In contrast, the shelves of every mathematics library groan under the weight of books on linear algebra, some of which contain short chapters on determinants but usually only on those aspects of the subject which are applicable to the chapters on matrices. There appears to be tacit agreement among authorities on linear algebra that determinant theory is important only as a branch of matrix theory. In sections devoted entirely to the establishment of a determinantal relation, many authors de ne a determinant by rst de ning a matrixM and then adding the words: ¿Let detM be the determinant of the matrix M¿ as though determinants have no separate existence. This belief has no basis in history.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.

Buch. Condición: Neu. Neuware -Introduction to Large Truncated Toeplitz Matrices is a text on the application of functional analysis and operator theory to some concrete asymptotic problems of linear algebra. The book contains results on the stability of projection methods, deals with asymptotic inverses and Moore-Penrose inversion of large Toeplitz matrices, and embarks on the asymptotic behavoir of the norms of inverses, the pseudospectra, the singular values, and the eigenvalues of large Toeplitz matrices. The approach is heavily based on Banach algebra techniques and nicely demonstrates the usefulness of C\*-algebras and local principles in numerical analysis. The book includes classical topics as well as results obtained and methods developed only in the last few years. Though employing modern tools, the exposition is elementary and aims at pointing out the mathematical background behind some interesting phenomena one encounters when working with large Toeplitz matrices. The text is accessible to readers with basic knowledge in functional analysis. It is addressed to graduate students, teachers, and researchers with some inclination to concrete operator theory and should be of interest to everyone who has to deal with infinite matrices (Toeplitz or not) and their large truncations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condición: Neu. Neuware -Formal Semantics and Proof Techniques for Optimizing VHDL Models presents a formal model of VHDL that clearly specifies both the static and dynamic semantics of VHDL. It provides a mathematical framework for representing VHDL constructs and shows how those constructs can be formally manipulated to reason about VHDL. The dynamic semantics is presented as a description of what the simulation of VHDL means. In particular it specifies what values the signals of a VHDL description will take if the description were to be executed. An advantage of the approach is that the semantic model can be used to validate different simulation algorithms. The book also presents an embedding of the dynamic semantics in a proof checker which is then used to prove equivalences of classes of VHDL descriptions.Formal Semantics and Proof Techniques for Optimizing VHDL Models is written for hardware designers who are interested in the formal semantics of VHDL.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 184 pp. Englisch.

Buch. Condición: Neu. Neuware -Survivable Networks: Algorithms for Diverse Routing provides algorithms for diverse routing to enhance the survivability of a network. It considers the common mesh-type network and describes in detail the construction of physically disjoint paths algorithms for diverse routing. The algorithms are developed in a systematic manner, starting with shortest path algorithms appropriate for disjoint paths construction. Key features of the algorithms are optimality and simplicity. Although the algorithms have been developed for survivability of communication networks, they are in a generic form, and thus applicable in other scientific and technical disciplines to problems that can be modeled as a network.A notable highlight of this book is the consideration of real-life telecommunication networks in detail. Such networks are described not only by nodes and links, but also by the actual physical elements, called span nodes and spans. The sharing of spans (the actual physical links) by the network (logical) links complicates the network, requiring new algorithms. This book is the first one to provide algorithms for such networks.Survivable Networks: Algorithms for Diverse Routing is a comprehensive work on physically disjoint paths algorithms. It is an invaluable resource and reference for practicing network designers and planners, researchers, professionals, instructors, students, and others working in computer networking, telecommunications, and related fields.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Condición: Neu. Neuware -The concept of 'reformulation' has long been playing an important role in mathematical programming. A classical example is the penalization technique in constrained optimization that transforms the constraints into the objective function via a penalty function thereby reformulating a constrained problem as an equivalent or approximately equivalent unconstrained problem. More recent trends consist of the reformulation of various mathematical programming prob lems, including variational inequalities and complementarity problems, into equivalent systems of possibly nonsmooth, piecewise smooth or semismooth nonlinear equations, or equivalent unconstrained optimization problems that are usually differentiable, but in general not twice differentiable. Because of the recent advent of various tools in nonsmooth analysis, the reformulation approach has become increasingly profound and diversified. In view of growing interests in this active field, we planned to organize a cluster of sessions entitled 'Reformulation - Nonsmooth, Piecewise Smooth, Semismooth and Smoothing Methods' in the 16th International Symposium on Mathematical Programming (ismp97) held at Lausanne EPFL, Switzerland on August 24-29, 1997. Responding to our invitation, thirty-eight people agreed to give a talk within the cluster, which enabled us to organize thirteen sessions in total. We think that it was one of the largest and most exciting clusters in the symposium. Thanks to the earnest support by the speakers and the chairpersons, the sessions attracted much attention of the participants and were filled with great enthusiasm of the audience. 456 pp. Englisch.

Buch. Condición: Neu. Neuware -Distraction osteogenesis is a technique of bone lengthening developed by the late Dr. Ilizarov of Russia. It has been applied to the lower extremities with amazing success for the correction of non-unions following fractures as well as underdeveloped limbs. Dr. McCarthy and his colleagues at NYU have developed techniques of distracting various components of the craniofacial skeleton. These techniques hold considerable promise for reconstructive surgery, allowing the surgeon to make precise changes in the lenthening and shape of the new craniofacial bone. This volume is the first book of its kind, bringing together the pioneers of these revolutionary new techniques. An international group of experts present their clinical and laboratory experience with destraction of the cranial vault, orbit, midface and zygoma, and mandible, as well as the prinicples of distraction, biomechanics, and the physiology of bone healing and remodeling. Two hundred illustrations elucidate the techniques. This book is a must for all reconstructive plastic surgeons, maxillofacial surgeons, and oral surgeons. 464 pp. Englisch.

Buch. Condición: Neu. Neuware -The interest for :I:~ modulation-based NO converters has significantly increased in the last years. The reason for that is twofold. On the one hand, unlike other converters that need accurate building blocks to obtain high res olution, :I:~ converters show low sensitivity to the imperfections of their building blocks. This is achieved through extensive use of digital signal pro cessing - a desirable feature regarding the implementation of NO interfaces in mainstream CMOS technologies which are better suited for implementing fast, dense, digital circuits than accurate analog circuits. On the other hand, the number of applications with industrial interest has also grown. In fact, starting from the earliest in the audio band, today we can find :I:~ converters in a large variety of NO interfaces, ranging from instrumentation to commu nications. These advances have been supported by a number of research works that have lead to a considerably large amount of published papers and books cov ering different sub-topics: from purely theoretical aspects to architecture and circuit optimization. However, so much material is often difficultly digested by those unexperienced designers who have been committed to developing a :I:~ converter, mainly because there is a lack of methodology. In our view, a clear methodology is necessary in :I:~ modulator design because all related tasks are rather hard. 312 pp. Englisch.

Buch. Condición: Neu. Neuware -Although limnology is a young discipline, it has, over the past century, experi enced marked growth. Its early descriptive period was a long one, given the enormous diversity of biota and environments in freshwater ecosystems. With the development of quantitative techniques came the ability to measure production rates and other parameters and to demonstrate the effects of nutrient limitation and predation on productivity and energy flow. As understanding of these phenomena grew, so too did our appreciation of the many complex chemical interactions among the biotic and habitat components of freshwater ecosystems. A recent, exciting phase of limnology, which may be called biochemical lim nology, is evolving rapidly. One of its many facets is the study of population and community dynamics at basic physiological levels. Examples are many. The integration of recent studies of food biochemistry with traditional studies of food quantity has begun to reveal the striking importance of food quality to reproduc tion and to the growth dynamics of many aquatic animals. Positive as well as negative alleleochemical interactions, already known in terrestrial ecosystems, are emerging as a major factor of many competitive interactions in fresh waters.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 336 pp. Englisch.

Buch. Condición: Neu. Neuware -A major goal of hearing research is to explain how the human auditory system normally functions and to help identify the causes of and treatments for hearing impairment. Experimental approaches to this research make use of animal models that are developed, evaluated and validated to determine what can be generalized from one species to another. By investigating the structures, physiological functions and hearing capabilities of various species, comparative hearing research establishes the biological and evolutionary context for such models. This volume brings together our current understanding of the auditory systems of two of the major vertebrate classes, fish and amphibians. It overcomes the differing theoretical and experimental paradigms that underlie most work on these groups and treats both fish and amphibians together in most chapters in order to address broader comparative issues.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 460 pp. Englisch.

Buch. Condición: Neu. Neuware - A basic issue in computer science is the complexity of problems. Computational complexity measures how much time or memory is needed as a function of the input problem size. Descriptive complexity is concerned with problems which may be described in first-order logic. By virtue of the close relationship between logic and relational databses, it turns out that this subject has important applications to databases such as analysing the queries computable in polynomial time, analysing the parallel time needed to compute a query, and the analysis of nondeterministic classes. This book is written as a graduate text and so aims to provide a reasonably self-contained introduction to this subject. The author has provided numerous examples and exercises to further illustrate the ideas presented.

Buch. Condición: Neu. Neuware -In this book, we give a rational treatment of multicomponent materials as intera- ingcontinua.Weoffertwoderivationsoftheequationsofmotionfortheinteracting continua; one which uses the concepts of continua for the components, and one which applies an averaging operation to the continuum equations for each c- ponent. Arguments are given for constitutive equations appropriate for dispersed multicomponent ow. The forms of the constitutive equations are derived from the principles of continuum mechanics applied to the components and their int- actions. The solutions of problems of hydromechanics of ordinary continua are used as motivation for the forms of certain constitutive equations in multicom- nent materials. The balance of the book is devoted to the study of problems of hydrodynamics of multicomponent ows. Many materials are homogeneous in the sense that each part of the material has the same response to a given set of stimuli as all of the other parts. An example of such a material is pure water. Formulation of equations describing the behavior of homogeneous materials is well understood, and is described in numerous standard textbooks. Many other materials, both manufactured and occurring in nature, are not - mogeneous. Such materials are often given names such as mixtures or composites.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Buch. Condición: Neu. Neuware -The idea for this book was conceived over the second bottle of Villa Maria's Caber net Medot '89, at the dinner of the Australasian Combinatorics Conference held at Palmerston North, New Zealand in December 1990, where the authors first met and discovered they had a number of interests in common. Initially, we embarked on a small project to try to formulate reductions to address the apparent parame terized intractability of DOMINATING SET, and to introduce a structure in which to frame our answers. Having spent several months trying to get the definitions for the reductions right (they now seem so obvious), we turned to our tattered copies of Garey and Johnson's work [239]. We were stunned to find that virtually none of the classical reductions worked in the parameterized setting. We then wondered if we'd be able to find any interesting reductions. Several years, many more bottles, so many papers, and reductions later it [3] seemed that we had unwittingly stumbled upon what we believe is a truly central and new area of complexity theory. It seemed to us that the material would be of great interest to people working in areas where exact algorithms for a small range of parameters are natural and useful (e. g. , Molecular Biology, VLSI design). The tractability theory was rich with distinctive and powerful techniques. The intractability theory seemed to have a deep structure and techniques all of its own.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 556 pp. Englisch.

Neuware -Human influences create both environmental problems and barriers to effective policy aimed at addressing those problems. In effect, environmental managers manage people as much as they manage the environment. Therefore, they must gain an understanding of the psychological and sociopolitical dimensions of environmental problems that they are attempting to resolve. In Environmental Problem Solving, Alan Miller reappraises conventional analyses of environmental problems using lessons from the psychosocial disciplines. He combines the disciplines of ecology, political sociology and psychology to produce a more adaptive approach to problem-solving that is specifically geared toward the environmetal field. Numerous case studies demonstrate the practical application of theory in a way that is useful to technical and scientific professionals as well as to policy makers and planners. Alan Miller is Professor of Psychology at the University of New Brunswick.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Ten years ago, the practical collaboration was begun of bringing together people who belonged to the complementary streams of economic analysis and policy analysis presented int his book. During this time, we opened discussions on the relationship between transportation technology, transportation economics and transportation policy under the general auspices of the Canadian Royal Commission on National Passenger Transportation. Working over a 40-month period (1989-1992), this Commission took stock of transportation and produced an up-to-date `État de la question' and policy framework (Hyndman, et al, 1992). Clearly, the project committee's discussions on air policy, over the period 1995-1997 (see Chapter 8), outlined the possibilities for a mechanism to understand the differences about the desirability of air liberalisation, as well as the possible TEP interactions in this area. This led to an exploratory first formulation and computer programme (HLB, 1997) incorporating the approach outlined in Chapter 15.A joint celebration of the CRT's 25th birthday and Transport Canada's 60th birthday seemed appropriate to bring together the various streams. Part I of Taking Stock of Air Liberalization looks at the record, and Part II focuses on specific impacts of policies. Policy formulation (Part III) and the required tools (Part IV - Modelling Demand) are also discussed in this context. The book ends with perspectives in Part V - The Future Market Structure and Public Policy. The competition among airlines is rapidly spreading to the competition among airports, and the difficult regulation of these strategic spatial monopolies (which is introduced in Chapter 13) is now attracting research activity. The next discussion in the airline industry will be the role of airports.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Neuware -In the centennial year of the birth of Sir John Cockcroft, first master of my Cam bridge College, Churchill, and the first man to split the atomic nucleus by artificial means, it is indeed relevant to consider the outcome of his efforts at developing atomic power. From the earliest days of the construction of Calder Hall-the first nuclear power station in Britain-and the establishment of the British Atomic Re search Center at Harwell, and the Chalk River Nuclear Station in Canada, through the 'Windscale' nuclear accident in Britain, up to the present, when some 20% of UK energy is derived from nuclear power, the Cockcroft legacy is felt. As the British historian Mark Goldie put it, in the 'pure and sanguine 1950s,' Cockcroft had almost absolute 'faith in 'peaceful atoms' and in the boundless, almost cost free, energy that atoms would soon produce' (Goldie, 1997, p. 21). But, as the eminent economist Frank Hahn recalled, 'the only failing Cockcroft had' was 'that he wasn't up to much in economics. ' Indeed, Hahn recalled that he 'had to explain' to Cockcroft 'the economic notion of optimum durability' as it related to the 'interest rate' in the context of building Churchill College with 'hand-made bricks. ' After his explana tion, as Hahn recalled 'Cockcroft smiled and proceeded to order more hand-made bricks' (Hahn, 1997, p. 27).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 140 pp. Englisch.

Neuware -Rate-Quality Optimized Video Coding discusses the matter of optimizing (or negotiating) the data rate of compressed digital video and its quality, which has been a relatively neglected topic in either side of image/video coding and tele-traffic management. Video rate management becomes a technically challenging task since it is required to maintain a certain video quality regardless of the availability of transmission or storage media. This is caused by the broadband nature of digital video and inherent algorithmic features of mainstream video compression schemes, e.g. H.261, H.263 and MPEG series. In order to maximize the media utilization and to enhance video quality, the data rate of compressed video should be regulated within a budget of available media resources while maintaining the video quality as high as possible.In Part I (Chapters 1 to 4) the non-stationarity of digital video is discussed. Since the non-stationary nature is also inherited from algorithmic properties of international video coding standards, which are a combination of statistical coding techniques, the video rate management techniques of these standards are explored. Although there is a series of known video rate control techniques, such as picture rate variation, frame dropping, etc., these techniques do not view the matter as an optimization between rate and quality. From the view of rate-quality optimization, the quantizer is the sole means of controling rate and quality. Thus, quantizers and quantizer control techniques are analyzed, based on the relationship of rate and quality.In Part II (Chapters 5 and 6), as a coherent approach to non-stationary video, established but still thriving nonlinear techniques are applied to video rate-quality optimization such as artificial neural networks including radical basis function networks, and fuzzy logic-based schemes. Conventional linear techniques are also described before the nonlinear techniques are explored. By using these nonlinear techniques, it is shown how they influence and tackle the rate-quality optimization problem. Finally, in Chapter 7 rate-quality optimization issues are reviewed in emerging video communication applications such as video transcoding and mobile video. This chapter discusses some new issues and prospects of rate and quality control in those technology areas.Rate-Quality Optimized Video Coding is an excellent reference and can be used for advanced courses on the topic.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Neuware -Farmers, Gene Banks and Crop Breeding: Economic Analyses of Diversity in Wheat, Maize, and Rice responds to concerns about the loss of valuable genetic resources and crop vulnerability arising from widespread cultivation of genetically uniform varieties. It assembles a series of applied studies focusing on the fundamental economic issues related to genetic diversity in crop species, with special reference to developing countries. By presenting the results of initial economic investigations of diversity in the world's three major food crops (wheat, maize, and rice),this volume furthers the understanding of the economic context in which crop breeders make use of genetic resources and their diversity.Farmers, Gene Banks and Crop Breeding: Economic Analyses of Diversity in Wheat, Maize, and Rice responds to current concerns about the loss of valuable genetic resources and crop vulnerability arising from the widespread cultivation of genetically uniform varieties. Previous work by economists in the study of biodiversity has been largely theoretical and has emphasized species diversity. In contrast, this book offers concrete steps in methods and conceptual development, providing an annotated catalog of the tools used to measure and value genetic diversity.The book will appeal to international agricultural research institutions, to international development organizations and NGOs, and to students and professors in departments of agricultural and resource economics who are concerned with the problem of biodiversity. 292 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book discusses the practical aspects of electrical and thermal modeling of packages. In addition, processing concerns for plastic packaged GaAs parts are also covered. The book emphasizes low cost industry standard packages. However, the principles involved translate well to other categories of packages. Digital issues such as crosstalk are well documented in other books and are therefore not covered in detail in this text. The principles for generation of equivalent circuit package models applies to both digital and analog parts. Digital designers and packaging engineers should still find this text useful. Subtleties often overlooked by standard methods of modeling packages for digital applications are considered and will become more important to the digital packaging engineer as frequencies continue to increase. It is hoped this book will be useful to both microwave and digital integrated circuit (Ie) designers as well as packaging engineers. In the past these disciplines were distinct. Packaging engineers typically were concerned with only materials and mechanical issues of the package. As long as there was an electrical connection made from the die to the external pin, packaging engineers had the freedom to do anything they wanted between these two points. At high frequency the issues change. Packaging engineers now have to work with die level designers to either create a package that performs well at high frequencies or to use readily available low cost packages that happen to meet the needs of the application.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Neuware -The Ninth Annual Pezcoller Symposium entitled 'The Biology of Tumors' was held in Rovereto, Italy, June 4-7, 1997. It focused on the genetic mechanisms underlying het erogeneity of tumor cell populations and tumor cell differentiation, on interactions be tween tumor cells and cells of host defenses, and the mechanisms of angiogenesis. With presentations at the cutting edge of progress and stimulating discussions, this symposium addressed issues related to phenomena concerned with cell regulation and cell interactions as determined by activated genes through the appropriate and timely media tion of gene products. Important methodologies that would allow scientists to measure dif ferentially genes and gene products and thus validate many of the mechanisms of control currently proposed were considered, as were the molecular basis of tumor recognition by the immune system, interactions between cells and molecular mechanisms of cell regula tion as they are affected by or implemented through these interactions. The molecular and cellular mechanisms of tumor vascularization were also discussed. It was recognized that angiogenesis provides a potential site of therapeutic intervention and this makes it even more important to understand the mechanisms underlying it. We wish to thank the participants in the symposium for their substantial contribu tions and their participation in the spirited discussions that followed. We would also like to thank Drs.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.
