Taschenbuch. Condizione: Neu. Neuware -The ultimate goal of all 3D graphics systems is to render 3Dobjects on a two-dimensional surface such as plotter output or a workstation screen. The approach adopted by most graphics systems is to perform a central or parallel projection of the objects onto the view surface. These systems have to make use of the mathematical results of projective geometry. This monograph has as its aim the derivation of a framework for analyzing the behavior of projective transformations in graphics systems. It is shown that a mathematically precise description of the projective geometrical nature of a graphics system leads not only to a deeper understanding of the system but also to new approaches which result in faster or more precise algorithms. A further aim of the book is to show the importance of advanced mathematics for computer science. Many problems become easier to describe or to solve when the appropriate mathematical tools are used. The author demonstrates that projective geometry has a major role to play in computer graphics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book contains a revised version of my Habilitationsschrift which has been accepted by the economic department of Dortmund University in 1991. It consists mostly of unpublished material which has been presented during the last years at the universities of Cologne, Dortmund, Hagen, Mannheim, and Munich and at a meeting in Wiesbaden. I am indebted to very many collegues for fruitful discussions. In par ticular, I want to thank Friedrich Breyer, Johannes Hoffmann, Heinz Hollander, Wolfgang Leininger, Bruno Schonfelder, Gerhard Schwodi auer, Hans-Werner Sinn, Klaus Spremann, and lochen Weimann, but this list is surely incomplete. I am especially grateful, however, to Wolfram F. Richter and Niko Wolik who have continually accompanied the evolution of this work and to whom lowe many suggestions as well as corrections. The remaining errors, needless to say, are mine. Cologne, September 1991 Stefan Homburg Contents Chapter 1. Introduction 1 Chapter 2.

Taschenbuch. Condizione: Neu. Neuware -The purpose of this book is to offer a small token in memory of Ken Hilton, who died prematurely at the age of 52 in February 1990. The book contains contributions from a number of 1eading academics; some were close c- leagues of Ken's at the University of Southampton, some have been at other universities but knew Ken fair1y well, and still some who never met Ken but who knew of him through bis work. The unifying motivation for all of them, however, was their immense sense of loss of an extremely proactive and excellent academic. Having led the research group on the Southampton Econometric Model project for three years, Ken was appointed to the Chair of Financia1 Control at the University of Southampton in 1970; at that time this was one of only a handful of similar Chairs in the UK. Most of Ken's subsequent academic career was devoted to contributing to the study of financial control, initially in the private sector and subsequently in the public sector. The breadth of bis interests was demonstrated by bis enviable ability to contribute to the areas of industrial economics, accounting, and management science. We hope therefore that this volume which embraces contributions from leading academics in each of these three fields is a fitting tribute to Ken's work.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The beauty of mathematics eludes all but a small, select handful of people. This monumental classic will illuminate the aesthetic delights of mathematics for all to behold. Why should only a tiny aristocracy hold the key to appreciating the elegance of mathematics Why should intelligent, cultured people, who can easily articulate the brilliance of Shakespeare's imagery, quake at the prospect of deciphering a simple algebraic formula Jerry King, a mathematics professor and a poet, razes the barriers between a world of two cultures and hands us the tools for appreciating the art and treasures of this elegant discipline. In his fluid, poetic voice, he initiates us into the splendid wonders of the Mathworld. He provides us with an original framework for contemplating mathematics as art. He deepens our ultimate comprehension of art by comparing the beauty of a Rembrandt as well as a Jackson Pollock with the riches to be mined in an elegant proof. Like the great philosophers of the past, Dr. King searches for pure Truth--a quest possible today only in the realm of mathematics. With his infectious enthusiasm, he explains with utmost clarity the intellectually stimulating underpinnings of both pure and applied mathematics. He goes on to decry how our educational system has failed by perfunctorily teaching us mathematics, depriving us of the pillars of beauty upon which mathematics rests. Never before has a book spoken so eloquently to our soul in instilling an appreciation for the grandeur of mathematics. Through Dr. King, the muses of mathematics will no longer sing for others and not for us. The elegant world of mathematics awaits us all to savor.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book is intended primarily to serve the needs of the undergraduate civil engineering student and aims at the clear explanation, in adequate depth, of the fundamental principles of soil mechanics. The understanding of these principles is considered to be an essential foundation upon which future practical experience in soils engineering can be built. The choice of material involves an element of personal opinion but the contents of this book should cover the requirements of most undergraduate courses to honours level. It is assumed that the student has no prior knowledge of the subject but has a good understanding of basic mechanics. The book includes a comprehensive range of worked examples and problems set for solution by the student to consolidate understanding of the fundamental principles and illustrate their application in simple practical situations. The International System of Units is used throughout the book. A list of references is included at the end of each chapter as an aid to the more advanced study of any particular topic. It is intended also that the book will serve as a useful source of reference for the practising engineer. In the third edition no changes have been made to the aims of the book. Except for the order of two chapters being interchanged and for minor changes in the order of material in the chapter on consolidation theory, the basic structure of the book is unaltered.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 432 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -After his stunning debut with Boosting the Underachiever: How Busy Parents Can Unlock Their Child's Potential, Dr. Victor Cogen, this time, focuses his unique vision on inspiring the adolescent underachiever - a normal, healthy teenager who just isn't getting the grades he or she should. Here, Dr. Cogen tackles the intricacies of the adolescent mind. His innovative approach goes beyond the stereotypical views of the teenage personality and teaches parents how they can personally take advantage of their adolescent's developing cognitive and emotional abilities. Adolescents are trapped between a world of fantasy created to help them escape from failure, and a growing need to become part of the real world of adults. This breathtaking book explains how to appeal to the developing and sensitive people these children are becoming and discover the source of their poor scholastic records. Publishers Weekly hailed Cogen's earlier book: 'Practical, jargon-free, the book offers realistic hope to parents willing to invest time helping their 'C student' children.' This book does the same for adolescents, a group known for shirking school work in pursuit of peer approval. Dr. Cogen underscores the crucial yet often overlooked role of emotion in learning - as both a positive and negative force. Using true-to-life scenarios and practical advice, Dr. Cogen - a leading psycho-educational consultant - presents a comprehensive program that will teach critical analytical skills and improve teenagers' self-perception so that they can overcome the emotional obstacles hampering their intellectual progress. The crux of Dr. Cogen's program requires the aid of a family roundtable discussion group. These sessions, as he describes, will encourage independent thinking as well as other qualities essential for a successful academic career. Rewards, cajoling, and threats may provide a temporary patch to cover a festering and far more dangerous wound. Parents cannot simply tell their adolescent what to do and expect results. With Dr. Cogen's revolutionary approach, you will learn how to capture your teenagers' attention and help them discover the fruits of learning for themselves.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -The term biotechnology has emerged on the contemporary scene fairly recently, but the basic concept of utilizing natural materials, either directly or in modified versions, dates back to antiquity. If we search the ancient literature, such as the Bible, we find hundreds of examples wherein people employed, or modified, natural materials for a variety of important uses. As far back as the days of Noah we find pitch, a natural material, being used as a caulk. Clothing was made from animal skins and the products of several plants. Today, we would consider these things as important biotechnological developments. Likewise, the human use of polymeric materials also has a long his tory. In fact, many of the original materials used by mankind were poly mers derived from nature, such as wood, flax, cotton, wool and animal skins, which were used for shelter and clothing. In recent years, however, the concept of biotechnology has taken on a new and renewed role in our society. This is due to a combination of factors, including an increased interest in environmental concerns and the desire to break free from the stranglehold that petrochemicals have placed on our society. If we can manufacture some of our polymers from renewable resources, then we can expect to prepare them for many more years into the future than we might if we could only depend on the petro chemical resources. 364 pp. Englisch.

Buch. Condizione: Neu. Neuware -This volume brings together a range of contributors from Europe and North America. All contributions were especially commissioned with a view to e- cidating a major multidisciplinary topic that is of concern to both academics and practitioners. The focus of the book is on expert judgment and its interaction with decision support systems. In the first part, the nature of expertise is discussed and characteristics of expert judges are described. Issues concemed with the eval- tion of judgment in the psychological laboratory are assessed and contrasted with studies of expert judgment in ecologically valid contexts. In addition, issues concerned with eliciting and validating expert knowledge are discussed. Dem- strations of good judgmental performance are linked to situational factors such as feedback cycles, and measurement of coherence and reliability in expert ju- ment is introduced as a baseline determinant of good judgmental performance. Issues concerned with the representation of elicited expert knowledge in kno- edge-based systems are evaluated and methods are described that have been shown to produce improvements in judgmental performance. Behavioral and mathematical ways of combining judgments from multiple experts are compared and contrasted. Finally, the issues developed in the preceding contributions are focused on current controversies in decision support. Expert judgment is utilized as a major input into decision analysis, forecasting with statistical models, and expert s- tems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware - This book is intended as a warning against the kind of hard-core liberalism which blames state intervention for the disappointing results achieved in matters of macroeconomic, competition and social welfare policy. In calling attention to the social dimension of economics, the book stresses the need for an ethical yardstick which can only be pro vided by an interdisciplinary approach to the economy. One current school of thought claims to have bridged the gap by por traying economics as both positive and normative. However, this inter pretation is inadequate. The positive aspect of economics, reflecting an approach common in the natural sciences, is based on observable facts. It highlights causal relationships and seeks to analyse economic mechanisms on the basis of available information. This has led to an emphasis on purely deductive methods, which form the basis for many of the conclusions in main stream economics. This current of thought is typified by the neoclassical school, which takes as its main premise the much-disputed hypothesis of economic rationality. Human behaviour is deemed to be rational when consumers maximize their satisfaction and producers their profits, sub ject to the constraints of income and production costs respectively. Opt imal strategies for both consumers and producers can best be determined by the mechanism of market forces.

Buch. Condizione: Neu. Neuware - This book contains papers presented at a conference held in Vimeiro, Por tugal, on March 23 and 24, 1991. The purpose of this conference was to discuss several aspects of the portuguese economy, namely issues and prob lems related with the european integration of 1992. The sponsorship has been provided by the Junta N acional de Investiga~iio Cientifica e Tecno logica, the portuguese science and technology foundation, as well as by the Banco de Portugal, the central bank. The first paper, by Horta Correia, Cesar das Neves and Rebelo repre sents an attempt to characterize and to analyze the main features of the portuguese business cycles. Making use of the real business cycle method ology, the authors contrast the properties of the portuguese empirical regu larities with those of other OEeD countries and conclude that the economic fluctuations in Portugal seem much more severe. On the other hand, the rel ative volatility of the various series analyzed, as well as their co-movement and serial correlation properties, are of the same order of those in other DECD countries. Horta Correia, Cesar das Neves and Rebelo evaluate the properties of the portuguese time series in light of the predictions of two dynamic general equilibrium models: a closed economy model and a model of a small open economy. Surprisingly, their closed economy model provides a good fit for the portuguese fluctuations, while the small open economy model predicts unplausibly low volatilities for both aggregate consumption and the trade balance.

Buch. Condizione: Neu. Neuware -This book is intended as a relatively nontechnica1 introduction to eurrent demographie methods. It has been several years in preparation, beginning from occasional class handouts I wrote to elaborate on essential points of demographie methodology. Its growth from scattered notes to an integrated text was a natural process, if a gradual one. The eontent of the book addresses three objectives. first, I have tried to avoid demographie methods that are now dated. In some ehapters, that has meant eoncentrating on formulas most demographers recognize. In the ehap ters on life tables, it meant testing competing formulas on a variety of real and synthetie data se.ts, and dropping or relegating to footnotes those that were least accurate. Second, I have attempted to give readers a sense of the limits of different formulas and methods. I am a terse writer, however, and for the reader that means most sentences carry weight. Chapters should be read attentively, with careful regard to commentary as weIl as to formulas and examples. Finally, I have tried to make the principal methodologies of the book accessible, by offering explanations for formulas that are not obvious, by keeping examples to the forefront, and by placing relatively specialized topics in ehapter appendices.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Englisch.

Buch. Condizione: Neu. Neuware -These are the Proceedings of the NATO Advanced Study Institute on Approximation Theory, Spline Functions and Applications held in the Hotel villa del Mare, Maratea, Italy between April 28,1991 and May 9, 1991. The principal aim of the Advanced Study Institute, as reflected in these Proceedings, was to bring together recent and up-to-date developments of the subject, and to give directions for future research. Amongst the main topics covered during this Advanced Study Institute is the subject of uni variate and multivariate wavelet decomposition over spline spaces. This is a relatively new area in approximation theory and an increasingly impor tant subject. The work involves key techniques in approximation theory cardinal splines, B-splines, Euler-Frobenius polynomials, spline spaces with non-uniform knot sequences. A number of scientific applications are also highlighted, most notably applications to signal processing and digital im age processing. Developments in the area of approximation of functions examined in the course of our discussions include approximation of periodic phenomena over irregular node distributions, scattered data interpolation, Pade approximants in one and several variables, approximation properties of weighted Chebyshev polynomials, minimax approximations, and the Strang Fix conditions and their relation to radial functions. I express my sincere thanks to the members of the Advisory Commit tee, Professors B. Beauzamy, E. W. Cheney, J. Meinguet, D. Roux, and G. M. Phillips. My sincere appreciation and thanks go to A. Carbone, E. DePas cale, R. Charron, and B.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 500 pp. Englisch.

Buch. Condizione: Neu. Neuware -The main aim of this paper is to present some new and general results, ap plicable to the the equations of two phase flow, as formulated in geothermal reservoir engineering. Two phase regions are important in many geothermal reservoirs, especially at depths of order several hundred metres, where ris ing, essentially isothermal single phase liquid first begins to boil. The fluid then continues to rise, with its temperature and pressure closely following the saturation (boiling) curve appropriate to the fluid composition. Perhaps the two most interesting theoretical aspects of the (idealised) two phase flow equations in geothermal reservoir engineering are that firstly, only one component (water) is involved; and secondly, that the densities of the two phases are so different. This has led to the approximation of ignoring capillary pressure. The main aim of this paper is to analyse some of the consequences of this assumption, especially in relation to saturation changes within a uniform porous medium. A general analytic treatment of three dimensional flow is considered. Pre viously, three dimensional modelling in geothermal reservoirs have relied on numerical simulators. In contrast, most of the past analytic work has been restricted to one dimensional examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 306 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book is unique in that it brings together in one place an account of recent advances in our understanding of the biology of dyslexia. It grew out of a Rodin Remediation Foundation International conference held on this topic in Boulder, Colorado in 1990, which included most of the world's experts on the genetics and neurology of dyslexia. Ten years ago a volume on this topic would scarcely been possible, and now we have an emerging, comprehensive neuroscientific understanding of this complex behavioral disorder that goes from genes to brain to behavior. Building on recent advances in the understanding of the cognitive phenotype of dyslexia, these authors present new data on both the etiology and brain mechanisms underlying that phenotype. Reading disability or dyslexia has a high familial recurrence rate, and is partly heritable. Genetic linkage studies are beginning to identify the possible locations of genes influencing this phenotype. On the neurological side, several independent studies have found neuroanatomical differences in the dyslexic brain, which are due to early changes in brain development. Thus, contrary to the views held by some educators that dyslexia is a myth, the results presented in this book firmly establish dyslexia as a real, biological condition. This book is relevant to researchers and practitioners concerned with both normal and abnormal reading development.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condizione: Neu. Neuware -The subject of Elasticity can be approached from several points of view, depending on whether the practitioner is principally interested in the mathematicalstructure of the subject or in its use in engineering applications and in the latter case, whether essentially numerical or analytical methods are envisaged as the solution method. My first introduction to the subject was in response to a need for information about a specific problem in Tribology. As a practising engineer with a background only in elementary Strength of Materials, I approached that problem initially using the con cepts of concentrated forces and superposition. Today, with a rather more extensive knowledge of analytical techniques in Elasticity, I still find it helpful to go back to these roots in the elementary theory and think through a problem physically as well as mathematically, whenever some new and unexpected feature presents difficulties in research. This way of thinking will be found to permeate this book. My engineering background will also reveal itself in a tendency to work examples through to final expressions for stresses and displacements, rather than leave the derivation at a point where the remaining manipulations would be routine. With the practical engineering reader in mind, I have endeavoured to keep to a minimum any dependence on previous knowledge of Solid Mechanics, Continuum Mechanics or Mathematics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 322 pp. Englisch.

Buch. Condizione: Neu. Neuware -This monograph addresses two quite different topics, in the belief that each can shed light on the other. Firstly, it lays the foundation for a particular view of the bootstrap. Secondly, it gives an account of Edgeworth expansion. Chapter 1 is about the bootstrap, witih almost no mention of Edgeworth expansion; Chapter 2 is about Edgeworth expansion, with scarcely a word about the bootstrap; and Chapters 3 and 4 bring these two themes together, using Edgeworth expansion to explore and develop the properites of the bootstrap. The book is aimed a a graduate level audience who has some exposure to the methods of theoretical statistics. However, technical details are delayed until the last chapter (entitled 'Details of Mathematical Rogour'), and so a mathematically able reader without knowledge of the rigorous theory of probability will have no trouble understanding the first four-fifths of the book. The book simultaneously fills two gaps in the literature; it provides a very readable graduate level account of the theory of Edgeworth expansion, and it gives a detailed introduction to the theory of bootstrap methods.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book presents the latest developments in structural dynamics with particular emphasis on the formulation of equations of motion by finite element methods and their solution using microcomputers.The book discusses the use of frequency-dependent shape functions for realistic finite element modelling, as opposed to the approximate conventional shape functions. A useful feature of the book in handling the forced vibration problem is the separation of the solution into two parts; the steady state and transient. Advanced topics such as substructure and synthesis are viewed in a modern unified manner. A complete listing of the finite element programme NATVIB used is given. 308 pp. Englisch.

Buch. Condizione: Neu. Neuware -Shell structures are used in all phases of structures, from space vehicles to deep submergence hulls, from nuclear reactors to domes on sport arenas and civic buildings. With new materials and manufacturing methods, curved thin walled structures are being used increasingly.This text is a graduate course in the theory of shells. It covers shells of isotropic materials, such as metal alloys and plastics, and shells of composite materials, such as fibre reinforced polymer, metal or ceramic matrix materials. It provides the essential information for an understanding of the underlying theory, and solution of some of the basic problems. It also provides a basis to study the voluminous shell literature. Beyond being primarily a textbook, it is intended also for self study by practising engineers who would like to learn more about the behaviour of shells.The book has two parts: Part I deals with shells of isotropic materials. In this part the mathematical formulations are introduced involving curvilinear coordinates. The techniques of solutions and resulting behavior is compared to planar thin walled isotropic structures such as plates and beams.Part II then treats the behavior of shells, involving anisotropic composite materials, so widely used today. The analysis involves the complications due to the many elastic constants, effects of transverse shear deformation, thermal thickening and offer effects arising from the properties of composite materials.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 576 pp. Englisch.

Buch. Condizione: Neu. Neuware -Material technology has become so diversified in theories and the construction of novel microstructures that the researchers and practitioners are drifting further apart. This book is based on material presented at an International Symposium in Xanthi, Greece in July 1989. The symposium attracted a group of individual engineers and scientists from the East and West who tackled the question of why particular manipulations of a given material have particular effects. Emphasis is laid on the strain energy function because of the versatile role it plays in mechanics and physics. It has been used successfully not only in predicting the failure of solids but also in formulating constitutive relations in continuum mechanics.The material presented falls within the areas of: Fundamentals of Strain Energy Density, Damage Analysis on Strain Energy Density, Strain Energy Density as Failure Criterion, Applications, and Composites.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 238 pp. Englisch.

Buch. Condizione: Neu. Neuware -Fluorescence spectroscopy and its applications to the physical and life sciences have evolved rapidly during the past decade. The increased interest in fluorescence appears to be due to advances in time resolution, methods of data analysis, and improved instrumentation. With these advances, it is now practical to perform time-resolved measurements with enough resolution to compare the results with the structural and dynamic features of mac- molecules, to probe the structures of proteins, membranes, and nucleic acids, and to acquire two-dimensional microscopic images of chemical or protein distributions in cell cultures. Advances in laser and detector technology have also resulted in renewed interest in fluorescence for clinical and analytical chemistry. Because of these numerous developments and the rapid appearance of new methods, it has become difficult to remain current on the science of fluorescence and its many applications. Consequently, I have asked the experts in particular areas of fluorescence to summarize their knowledge and the current state of the art. This has resulted in the initial two volumes of Topics in Fluorescence Spectroscopy, which is intended to be an ongoing series which summarizes, in one location, the vast literature on fluorescence spectroscopy. The third volume will appear shortly. The first three volumes are designed to serve as an advanced text. These volumes describe the more recent techniques and technologies (Volume 1), the principles governing fluorescence and the experimental observables (Volume 2), and applications in biochemistry and biophysics (Volume 3).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 452 pp. Englisch.
