Buch. Condizione: Neu. Neuware - As miniaturization deepens, and nanotechnology and its machines become more prevalent in the real world, the need to consider using quantum mechanical concepts to perform various tasks in computation increases. Such talks include: the teleporting of information, breaking heretofore 'unbreakable' codes, communicating with messages that betray eavesdropping, and the generation of random munbers. To date, there has been no book written which applies quantum physics to the basic operations of a computer. This one does, thus presenting us with the ideal vehicle for explaining the complexities of quantum mechanics to students, researchers and computer engineers, alike, as they prepare to design and create the computing and information delivery systems for the future. Both authors have solid backgrounds in the subject matter at the theoretical and research level, as well as experience on a more practical plane. While also intended for use as a text for senior/grad level students in computer science/physics/engineering, this book has its primary use as an up-to-date reference work in the emerging interdisciplinary field of quantum computing. It does require knowledge of calculus and familiarity with the concept of the Turing machine.

Buch. Condizione: Neu. Neuware - Structured adaptive mesh refinement (SAMR) methods have matured over the past 20 years and are now the method of choice for certain difficult problems, such as compressible flow. SAMR presents difficult technical challenges, both in terms of the numerical techniques involved and the complexity of the programming effort, especially on parallel computers. In order to gain insight into managing these difficulties, much research effort has been directed at mesh generation, parallel computation, and improvements in accuracy, aimed primarily at refinement interfaces. A major stumbling block in this endeavor is that many of these techniques entail substantial amounts of problem specific detail. Standardization is highly unlikely, except within narrowly defined problem domains. The papers presented in this collection are based on talks given at the Workshop on Structured Adaptive Mesh Refinement Grid Methods, held at the Institute for Mathematics and its Applications, University of Minnesota, on March 12-13 1997. They describe research to improve the general understanding of the application of SAMR to practical problems; identify issues critical to efficient and effective implementation on high performance computers; stimulate the development of a community code repository for software including benchmarks to assist in the evaluation of software and compiler technologies. The ten chapters of this volume have been divided into two parts reflecting two major issues in the topic: (I) programming complexity of SAMR algorithms and (II) applicability and numerical challenges of SAMR methods.

Buch. Condizione: Neu. Neuware - A compact survey, at the elementary level, of some of the most important concepts of mathematics. Attention is paid to their technical features, historical development and broader philosophical significance. Each of the various branches of mathematics is discussed separately, but their interdependence is emphasised throughout. Certain topics - such as Greek mathematics, abstract algebra, set theory, geometry and the philosophy of mathematics - are discussed in detail. Appendices outline from scratch the proofs of two of the most celebrated limitative results of mathematics: the insolubility of the problem of doubling the cube and trisecting an arbitrary angle, and the Gödel incompleteness theorems. Additional appendices contain brief accounts of smooth infinitesimal analysis - a new approach to the use of infinitesimals in the calculus - and of the philosophical thought of the great 20th century mathematician Hermann Weyl. Readership: Students and teachers of mathematics, science and philosophy. The greater part of the book can be read and enjoyed by anyone possessing a good high school mathematics background.

Buch. Condizione: Neu. Neuware - CLAUDEJEANRENAUD NILS SOGUEL Smoking is a very common habit all over the world. The prevalence rate ranges from 20% - 40% in industrialised countries, and is dramatically increasing in the developing world. Smoking is risky and there is ample scientific evidence to support this statement. We know that smoking is a major cause of disease and premature death, in view of the fact that 3 million people die each year worldwide as a result of their smoking habit. Twenty years ago, the U. S. Surgeon General identified smoking as the single most important cause of morbidity and premature death (USDHEW, 1979). Tobacco consnmption reduces life expectancy vastly. Epidemiological research shows that people who have died from a smoking-related disease would, on average, have lived for an additional 15 years had they not been smokers (Warner, 1987). The economic analysis of tobacco consumption is a complex and challenging issue, which entails addressing many different questions. What is the economic burden of smoking and do smokers 'pay their way' How do individuals perceive their own health risks What is the effect of the addicting properties of nicotine on the behaviour of a rational, utility maximizing individual Lastly, what is the most effective way to discourage tobacco consumption In this context, the assessment of the social burden of smoking using a cost-of-illness framework has played a central role since the beginning of the seventies.

Buch. Condizione: Neu. Neuware - An understanding of emergent computation requires a profound revision of the most fundamental ideas. A noticeable attempt of such a rethinking is a world view in which natural systems are seen not as separate entities but as integrated parts of a unified whole. The book for the first time presents such a mathematical structure, which remarkably is based on integers as the single concept. As integers are considered to be the most fundamental entities irreducible to something simpler, this makes the mathematical structure a final theory, and thus we do not have to look for its explanation in terms of deeper concepts. The book is not only applicable to models of computation and optimization but also has scientific consequences, as it contributes to a rethinking of the most fundamental ideas about nature. Audience: The book is written at a level suitable for advanced undergraduate students and graduate students as well as research workers and practitioners in computer science information technology, mathematics and physics. The book is suitable as a reference or as supplementary reading material for an advanced graduate course. Only a basic knowledge of calculus is required.

Buch. Condizione: Neu. Neuware - Global pesticide use is currently estimated at approximately 2. 5 billion kg per year (Pimentel eta/. , 1998). To be effective, pesticides need to persist for a certain period of time. However, the longer their persistence, the greater the potential for transport of a fraction of the amount applied away from the target area. Pesticides are dispersed in the environment by water currents, wind, or biota. Pesticides can directly contaminate ground and surface waters by leaching, surface run-off and drift. Pesticides can also enter the atmosphere during application by evaporation and drift of small spray droplets, that remain airborne. Following application, pesticides may volatilise from the crop or the soil. Finally, wind erosion can cause soil particles and dust loaded with pesticides to enter the atmosphere. The extent to which pesticides enter the air compartment is dependent upon many factors: the properties of the substance in question (e. g. vapour pressure), the amount used, the method of application, the formulation, the weather conditions (such as wind speed, temperature, humidity), the nature of the crop and soil characteristics. Measurements at application sites reveal that sometimes more than half of the amount applied is lost into the atmosphere within a few days (Spencer and Cliath, 1990; Taylor and Spencer; 1990; Van den Berg et a/. , this issue).

Buch. Condizione: Neu. Neuware - This book contains more than the IEEE Standard 1149.4. It also contains the thoughts of those who developed the standard. Adam Osseiran has edited the original writings of Brian Wilkins, Colin Maunder, Rod Tulloss, Steve Sunter, Mani Soma, Keith Lofstrom and John McDermid, all of whom have personally contributed to this standard. To preserve the original spirit, only minor changes were made, and the reader will sense a chapter-to-chapter variation in the style of expression. This may appear awkward to some, although I found the Iack of monotonicity refreshing. A system consists of a specific organization of parts. The function of the system cannot be performed by an individual part or even a disorganized collection ofthe same parts. Testing has a system-like characteristic. Testing of a system does not follow directly from the testing of its parts, and a system built with testable parts can sometimes be impossible to test. Therefore, testability of the system must be organized. Some years ago, the IEEE published the boundary-scan Standard 1149.1. That Standard provided an architecture for digital VLSI chips. The chips designed with the 1149.1 architecture can be integrated into a testable system. However, many systems today contain both analog and digital chips. Even if all digital chips are compliant with the standard, the testability of a mixed-signal system cannot be guaranteed. The new Standard 1149.4, described in this book, extends the previous architecture to mixed-signal systems.

Buch. Condizione: Neu. Neuware - 'EURO'. The name of the single currency for the European Union has not been chosen casually by the Heads of State and Government during the Madrid Council of December 1995. After tough discus sions, it has been unanimously accepted. The intention was to recall to every single citizen that this new money would be his money, that it would be the expression of the new European environment carefully built since the 'fifties' to avoid any return to war and barbarism in Europe. Confidence and positive expectations for a better future put in the European construction have thus been clearly linked to the confidence in the new European currency and vice-versa. Euro notes and coins will be the first expression, clear, material and universal (for any European citizen being young or old, rich or poor, but also for the rest of the world) of a European identity alongside the national one. Obviously, it is of the outmost importance that the change over to the euro, be as smooth and as citizen-friendly as possible.

Buch. Condizione: Neu. Neuware - The wide range of possible performance criteria for business enterprises raises serious questions of definition and measurement. Indeed, measurement is at the heart of the analysis of success and failure of business operations, and much depends on the quality of the information that is available. The evaluation of business performance comes into sharp focus with the pUblication of companies' annual and semi-annual accounts, which are then followed by commentaries from stockbrokers and business analysts in reports to investors and in articles in the financial press. Captains of industry may not have to suffer the indignity of frequent public opinion polls that gauge the popularity of politicians. Nevertheless, they are plagued by a similar phenomenon, in that views expressed by analysts, customers, shareholders and investors, serve as powerful reminders to senior executives that the business world is subject to many upheavals and that even the most seemingly secure can suddenly fall from grace.

Buch. Condizione: Neu. Neuware - Combinatorial (or discrete) optimization is one of the most active fields in the interface of operations research, computer science, and applied math ematics. Combinatorial optimization problems arise in various applications, including communications network design, VLSI design, machine vision, air line crew scheduling, corporate planning, computer-aided design and man ufacturing, database query design, cellular telephone frequency assignment, constraint directed reasoning, and computational biology. Furthermore, combinatorial optimization problems occur in many diverse areas such as linear and integer programming, graph theory, artificial intelligence, and number theory. All these problems, when formulated mathematically as the minimization or maximization of a certain function defined on some domain, have a commonality of discreteness. Historically, combinatorial optimization starts with linear programming. Linear programming has an entire range of important applications including production planning and distribution, personnel assignment, finance, alloca tion of economic resources, circuit simulation, and control systems. Leonid Kantorovich and Tjalling Koopmans received the Nobel Prize (1975) for their work on the optimal allocation of resources. Two important discover ies, the ellipsoid method (1979) and interior point approaches (1984) both provide polynomial time algorithms for linear programming. These algo rithms have had a profound effect in combinatorial optimization. Many polynomial-time solvable combinatorial optimization problems are special cases of linear programming (e.g. matching and maximum flow). In addi tion, linear programming relaxations are often the basis for many approxi mation algorithms for solving NP-hard problems (e.g. dualheuristics).

Buch. Condizione: Neu. Neuware - The aim of the present book is to give, in a single volume, an introduction to the fields of transition, turbulence and combustion modelling of compressible flows and to provide the physical background for today's modelling approaches in these fields. The basic equations for compressible flows are presented (Ch. 1). The fundamental aspects of hydrodynamical instability are discussed (Ch. 2). along with transition prediction methods in industrial applications (Ch. 3). Turbulence modelling approaches ranging from single-point models (Ch. 4, 5) to large-eddy simulation techniques (Ch. 6), direct numerical simulations (Ch. 7) and turbulence combustion modelling (Ch. 8) are covered. The book addresses engineers and researchers, in industry or academia, who are entering into the fields of transition, turbulence or combustion modelling research or who need to apply turbulence or transition prediction methods in their work.

Buch. Condizione: Neu. Neuware - Mr. Chairman, ladies and gentlemen, with great pleasure I like to welcome you in the cityofGroningen and hope that you will have an enriching and enlighten ing discussion on the conference theme on risk management in blood trans fusion. The organisation of this symposium aims at scientific networking by discussing in an international forum the most important themes of current interest in relation to the state of the art in transfusion medicine. Dr. Cees Smit Sibinga took the initiative in 1976 to start organising the blood bank symposia as they were named in the beginning. Without doubt these symposia have contributed considerably to the development of transfusion medicine. To illustrate the fact that these symposia came to my attention I recollect that I have attended the symposium in 1978, chaired by Dr. Leo Vroman, in my capacity in those days of alderman deputy mayor of the city. So, it has been a long time since. After having been away from Groningen for 18 years I have been inaugurated last week as a mayor and it is a plcasure to be again in your midst. The scries of annual symposia on blood transfusion have contributed to mark the city of Groningen on the map of the international scientific world. A great number of prestigious institutes all over the world involved in the development of transfusion medicine have linked to Groningen and we are proud of that.

The book provides a extensive view of the state of the art in DNS and LES.

Buch. Condizione: Neu. Neuware - Seven years have elapsed since Dr. Renee Ford, editor-in-chief of Materials Technology, first suggested to me to publish a book on Functionally Graded Materials (FGMs). She said that the FGM concept, then largely unknown outside of Japan and a relatively few laboratories elsewhere, would be of great interest to everyone working in the materials field because of its potentially universal applicability. There was no book about FGMs in English at that time, although the number of research papers, review articles, and FGM conference proceedings had been increasing yearly. We discussed what the book should cover, and decided it should present a comprehensive description from basic theory to the most recent applications of FGMs. This would make it useful both as an introduction to FGMs for those simply curious about what this new materials field was all about, and also as a textbook for researchers, engineers, and graduate students in various material fields. The FGM Forum in Japan generously offered to support this publication program. is very difficult for an individual author to write a book that Because it covers such a wide range of various aspects of many different materials, I invited more than 30 eminent materials scientists throughout the world, who were associated with FGM research, to contribute selected topics. I also asked several leading researchers in this field to edit selected chapters: Dr. Barry H. Rabin, then at the U. S.

This item is printed on demand - it takes 3-4 days longer - Neuware -Although transits of planets across the Sun are rare (only Mercury and Venus orbit the Sun closer than us, and so can transit the Sun's disc) amateur astronomers can observe, record and image other kinds of transit, which are very much more frequent. Transit is in two parts, the first telling the fascinating story of the early scientific expeditions to observe transits. The second part is for practical observers, and explains how to observe transits of all sorts - even transits of aircraft as they fly between the observer and the Sun! 180 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -We are still learning about the large-scale structures of the universe. Abrams and Stecker describe what we currently know of the near and far universe, but what sets this book apart from the rest is the illustrations. Stecker has a collection of some of the best and most spectacular astronomical photographs ever taken. The book is mostly illustrated with black and white photographs, but the CD-ROM supplied with the book is a veritable explosion of beautiful colour images, far more than could be squeezed into any normal book. An added benefit of this is that by using an inexpensive inkjet printer, a reader can look at pictures on screen, or print them out in colour with 'photo quality'. 132 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The subject of partial differential equations holds an exciting and special position in mathematics. Partial differential equations were not consciously created as a subject but emerged in the 18th century as ordinary differential equations failed to describe the physical principles being studied. The subject was originally developed by the major names of mathematics, in particular, Leonard Euler and Joseph-Louis Lagrange who studied waves on strings; Daniel Bernoulli and Euler who considered potential theory, with later developments by Adrien-Marie Legendre and Pierre-Simon Laplace; and Joseph Fourier's famous work on series expansions for the heat equation. Many of the greatest advances in modern science have been based on discovering the underlying partial differential equation for the process in question. James Clerk Maxwell, for example, put electricity and magnetism into a unified theory by establishing Maxwell's equations for electromagnetic theory, which gave solutions for prob lems in radio wave propagation, the diffraction of light and X-ray developments. Schrodinger's equation for quantum mechanical processes at the atomic level leads to experimentally verifiable results which have changed the face of atomic physics and chemistry in the 20th century. In fluid mechanics, the Navier Stokes' equations form a basis for huge number-crunching activities associated with such widely disparate topics as weather forecasting and the design of supersonic aircraft. Inevitably the study of partial differential equations is a large undertaking, and falls into several areas of mathematics. 304 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The book lays algebraic foundations for real geometry through a systematic investigation of partially ordered rings of semi-algebraic functions. Real spectra serve as primary geometric objects, the maps between them are determined by rings of functions associated with the spectra. The many different possible choices for these rings of functions are studied via reflections of partially ordered rings.Readers should feel comfortable using basic algebraic and categorical concepts. As motivational background some familiarity with real geometry will be helpful. The book aims at researchers and graduate students with an interest in real algebra and geometry, ordered algebraic structures, topology and rings of continuous functions. 300 pp. Englisch.

He examines Star Trek as a series of generic and mythological texts, compares TV and filmed versions, explores its 'cult' appeal and looks in detail at its psychological, social and political themes. 225 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A collection of essays by a Nobel Prize Laureate on a wide range of critical issues facing the world, and the role of scientists in solving these problems. Kendall has been closely involved with the Union of Concerned Scientists, a group that began as an informal assocation at MIT in 1969 to protest US involvement in Vietnam and is today an organization with an annual budget exceeding $6 million, with 100,000 supporters worldwide. UCD is today a voice of authority in US government science policy, particularly with regard to environment issues, most recently the worldwide initiatives on global warming. Together, these essays represent both the sucessses and failures of science to impact public policy, the challenges facing scientists, and offers practical guidelines for involvement in science policy. The essays are roughly chronological, organized by subject with introductions, beginning with the controversies on nuclear power safety and Three Mile Island,then followed by sections on national security issues, global environmental and resource problems,and radioactive cleanup and other current issues. Kendall's Nobel Prize lecture as well as a more popular version thereof is also included (and is the only really technical material in the book). The photos in the book are Kendall's, from an 1992 exhibition of his work. Henry Kendall was awarded the Nobel Prize in physics (jointly with J.I.Friedman and R.E. Taylor) in 1990 for his research in the structure of the proton and netron. In 1969, he was one of a group of physicist who founded the Union of Concerned Scientists (UCS) and is currently Chairman of its Board of Directors. 318 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -During the early years of the Second World War, Britain devoted immense resources to building military bases in Egypt and Palestine. The political stability of the two countries was of prime concern to avoid diverting troops away from fighting the external enemy to internal security tasks. The paradox of Britain's eventual victory was that it could not perpetuate its political authority. Demands for independence intensified in Egypt and among Palestinian Jewry, and led to postwar struggles. 308 pp. Englisch.

Three themes have been selected in this respect: - Evolution and Change in Data Management (ECDM'99) dealing with han dling the evolution of data and data structure, - Reverse Engineering in Information Systems (REIS'99) aimed at exploring the issues raised by legacy systems, - The World Wide Web and Conceptual Modehng (WWWCM'99) which ana lyzes the mutual contribution of WWW resources and techniques with con ceptual modeling. ER'99 has been organized so that there is no overlap between conference ses sions and the workshops. Therefore participants can follow both the conference and the workshop presentations they are interested in. I would like to thank the ER'99 program co-chairs, Jacky Akoka and Mokrane Bouzeghoub for having given me the opportunity to organize these workshops. I would also like to thank Stephen Liddle for his valuable help in managing the evaluation procedure for submitted papers and helping to prepare the workshop proceedings for publication. August 1999 Jacques Kouloumdjian Preface for ECDM'99 The first part of this volume contains the proceedings of the First International Workshop on Evolution and Change in Data Management, ECDM'99, which was held in conjunction with the 18th International Conference on Conceptual Modehng (ER'99) in Paris, France, November 15-18, 1999. 408 pp. Englisch.

An increase of interest in ADG '98 over the previous workshop ADG '96 is represented by the notable number of more than 40 participants from ten countries and the strong tech- cal program of 25 presentations, of which two one-hour invited talks were given by Professors Wen-tsun Wu and Jing-Zhong Zhang. The workshop provided the participants with a well-focused forum for e ective exchange of new ideas and timely report of research progress. Insight surveys, algorithmic developments, and applications in CAGD/CAD and computer vision presented by active - searchers, together with geometry software demos, shed light on the features of this second workshop. ADG '98 was hosted by the Mathematics Mechanization Research Center (MMRC) with nancial support from the Chinese Academy of Sciences and the French National Center for Scienti c Research (CNRS), and was organized by the three co-editors of this proceedings volume. The papers contained in the volume were selected, under a strict refereeing procedure, from those presented at ADG '98 and submitted afterwards. Most of the 14 accepted papers were carefully revised and some of the revised versions were checked again by external reviewers. We hope that these papers cover some of the most recent and signi cant research results and developments and re ect the current state-of-the-art of ADG. 300 pp. Englisch.
