Taschenbuch. Condizione: Neu. Neuware -Around 1994 R. Borcherds discovered a new type of meromorphic modular form on the orthogonal group $O(2,n)$. These 'Borcherds products' have infinite product expansions analogous to the Dedekind eta-function. They arise as multiplicative liftings of elliptic modular forms on $(SL)_2(R)$. The fact that the zeros and poles of Borcherds products are explicitly given in terms of Heegner divisors makes them interesting for geometric and arithmetic applications. In the present text the Borcherds' construction is extended to Maass wave forms and is used to study the Chern classes of Heegner divisors. A converse theorem for the lifting is proved.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book provides an approach to the study of perturbation and discretization effects on the long-time behavior of dynamical and control systems. It analyzes the impact of time and space discretizations on asymptotically stable attracting sets, attractors, asumptotically controllable sets and their respective domains of attractions and reachable sets. Combining robust stability concepts from nonlinear control theory, techniques from optimal control and differential games and methods from nonsmooth analysis, both qualitative and quantitative results are obtained and new algorithms are developed, analyzed and illustrated by examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Buch. Condizione: Neu. Neuware -In many areas of finance and stochastics, significant advances have been made since this field of research was opened by Black, Scholes and Merton in 1973. Advances in Finance and Stochastics contains a collection of original articles by a number of highly distinguished authors on research topics that are currently in the focus of interest of both academics and practitioners. The topics span risk management, portfolio theory and multi-asset derivatives, market imperfections, interest-rate modelling and exotic options.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 336 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Many introductory books on mathematical finance also outline some com puter algorithms. My goal is to contribute a closer look at algorithmic issues that arise from complex forms of the underlying pricing models-issues many practitioners need to solve sooner or later in their careers. This book takes such a close look at uncertain volatility models, an exten sion of Black-Scholes theory.It discusses applications to exotic option portfo lios with barriers and early exercise features. It describes an object-oriented C++ solution, included in source code on the accompanying CD. Practitioners and students who need to build analytic software libraries may benefit from reading this book and studying the software. The book focuses on a family of mathematical models, while in the field one encounters greater variation in instrument properties. In both cases mathematical and financial knowledge must be complemented by good programming skills to produce the best system. Analytic software needs design-a central message of the later chapters of this book. This book has come out of my Ph.D. thesis. I am very grateful to my academic advisor, Marco Avellaneda of New York University, who taught me mathematical finance and uncertain volatility. Computational finance be came exciting for me because Marco encouraged an algorithmic approach to uncertain volatility. I thank Afshin Bayrooti, Vladimir Finkelstein, and Antonio Paras for giving valuable feedback. Antonio is the co-inventor of the original uncertain volatility model, A-UVM. Richard Holmes has found a crucial bug in an early implementation of the software.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The ACM Workshop on Security and Privacy in Digital Rights Management is the rst scienti c workshop with refereed proceedings devoted solely to this topic. The workshop was held in conjunction with the Eighth ACM Conference on Computer and Communications Security (CCS-8) in Philadelphia, USA on November 5, 2001. Digital Rights Management technology is meant to provide end-to-end so- tions for the digital distribution of electronic goods. Sound security and privacy features are among the key requirements for such systems. Fifty papers were submitted to the workshop, quite a success for a rst-time workshop. From these 50 submissions, the program committee selected 15 papers for presentation at the workshop. They cover a broad area of relevant techniques, including cryptography, system architecture, and cryptanalysis of existing DRM systems. Three accepted papers are about software tamper resistance, an area about which few scienti c articles have been published before. Another paper addresses renewability of security measures. Renewability is another important security technique for DRM systems, and I hope we will see more publications about this in the future. I am particularly glad that three papers cover economic and legal aspects of digital distribution of electronic goods. Technical security measures do not exist in a vacuum and their e ectiveness interacts in a number of ways with the environment for legal enforcement. Deploying security and an- piracy measures adequately requires furthermore a good understanding of the business models that they are designed to support. 260 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Sapere aude! Immanuel Kant (1724-1804) Numerical simulations playa key role in many areas of modern science and technology. They are necessary in particular when experiments for the underlying problem are too dangerous, too expensive or not even possible. The latter situation appears for example when relevant length scales are below the observation level. Moreover, numerical simulations are needed to control complex processes and systems. In all these cases the relevant problems may become highly complex. Hence the following issues are of vital importance for a numerical simulation: - Efficiency of the numerical solvers: Efficient and fast numerical schemes are the basis for a simulation of 'real world' problems. This becomes even more important for realtime problems where the runtime of the numerical simulation has to be of the order of the time span required by the simulated process. Without efficient solution methods the simulation of many problems is not feasible. 'Efficient' means here that the overall cost of the numerical scheme remains proportional to the degrees of freedom, i. e. , the numerical approximation is determined in linear time when the problem size grows e. g. to upgrade accuracy. Of course, as soon as the solution of large systems of equations is involved this requirement is very demanding.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The aim of this book is to present a recently developed approach suitable for investigating a variety of qualitative aspects of order-preserving random dynamical systems and to give the background for further development of the theory. The main objects considered are equilibria and attractors. The effectiveness of this approach is demonstrated by analysing the long-time behaviour of some classes of random and stochastic ordinary differential equations which arise in many applications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book addresses a subject at the crossing point of two lines of investi gation - synergetics and modern nonlinear optics. First, the book is devoted to optical patterns that previously were mainly attributed to the display of instabilities of homogeneous field distributions. Second, we deal with optical bistability and hysteresis, which historically were studied predominantly for point (lumped, spatially nondistributed) systems. In the book, which seems to be the first monograph devoted to opti cal patterns, I attempt to demonstrate that the variety of optical patterns and other synergetical phenomena is especially rich in spatially distributed bistable systems, and that instabilities of homogeneous states are not neces sary for the formation of the patterns. Of special interest are patterns such as dissipative optical solitons, which individually have particle-like features and when combined resemble molecules, crystals, biological objects, and even social groups. Another essential point is the key role of inhomogeneities of bistable sys tems. As for hysteresis, it has been studied mostly in point systems, in which, with fixed characteristics of the input signal, one of several sets of steady state output signal characteristics can form, depending on the prehistory. In spatially distributed optical systems, the kinetics of hysteresis acquires the form of 'spatial hysteresis', or hysteresis of spatial distributions of field char acteristics. This problem of 'stereoscopic vision' of such hysteresis was solved in optical bistability some 20 years ago, and the concepts proposed were later confirmed and expanded.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -TheAdvanced Course onArti cial IntelligenceACAI2001, with the subtitle of ¿Multi- Agent Systems and Their Applications¿, held in Prague, Czech Republic, represented a joint event of ECCAI (the European Coordinating Committee for Arti cial Intel- gence) andAgentLink, the European Network of Excellence forAgent-Based Comp- ing. Whereas ECCAI organizes two-weekACAI courses on different topics each second year, AgentLink¿s European Agent Systems Summer School (EASSS) has been an - nual event since 1999. In 2001, both of these important events were merged, giving weight to the fact that multi-agent systems currently represent one of the hottest topics of AI research. The name, ACAI2001 Summer School, was intended to emphasize that this event continued the tradition of regular ECCAI activities (ACAI), as well as that of the EASSS summer schools ofAgentLink. The PragueACAI Summer School was proposed and initiated by both the Gerstner Laboratory, Czech Technical University, Prague (GL-CTU) and the Czech Society for Cybernetics and Informatics (CSKI), with the support of theAustrian Research Institute forArti cial Intelligence in Vienna (OFAI). One of the most important stimulating factors behind the organization ofACAI2001 wasthesupportprovidedbytheEuropeanCommissiontotheGerstnerLaboratorywithin the frame of the MIRACLE Centre of Excellence project (No. ICA1-CT-2000-70002). Additional support was later provided by both the Commission¿s AgentLink II project (IST-1999-29003) and ECCAI. The combined nancial and conceptual participation of these important international bodies enabled the invitation of a large number of truly world-class lecturers in this eld, who added a unique avor to the event. 396 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Program construction is about turning specifications of computer software into implementations. Recent research aimed at improving the process of program construction exploits insights from abstract algebraic tools such as lattice theory, fixpoint calculus, universal algebra, category theory, and allegory theory.This textbook-like tutorial presents, besides an introduction, eight coherently written chapters by leading authorities on ordered sets and complete lattices, algebras and coalgebras, Galois connections and fixed point calculus, calculating functional programs, algebra of program termination, exercises in coalgebraic specification, algebraic methods for optimization problems, and temporal algebra.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 404 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume is a self-contained introduction to interactive proof in high- order logic (HOL), using the proof assistant Isabelle 2002. Compared with existing Isabelle documentation, it provides a direct route into higher-order logic, which most people prefer these days. It bypasses rst-order logic and minimizes discussion of meta-theory. It is written for potential users rather than for our colleagues in the research world. Another departure from previous documentation is that we describe Markus Wenzel¿s proof script notation instead of ML tactic scripts. The l- ter make it easier to introduce new tactics on the y, but hardly anybody does that. Wenzel¿s dedicated syntax is elegant, replacing for example eight simpli cation tactics with a single method, namely simp, with associated - tions. The book has three parts. ¿ The rst part, Elementary Techniques, shows how to model functional programs in higher-order logic. Early examples involve lists and the natural numbers. Most proofs are two steps long, consisting of induction on a chosen variable followed by the auto tactic. But even this elementary part covers such advanced topics as nested and mutual recursion. ¿ The second part, Logic and Sets, presents a collection of lower-level tactics that you can use to apply rules selectively. It also describes I- belle/HOL¿s treatment of sets, functions, and relations and explains how to de ne sets inductively. One of the examples concerns the theory of model checking, and another is drawn from a classic textbook on formal languages.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Eine optimale Balance zwischen Erfahrung und Innovation ist ein wesentlicher Ausgangsfaktor für erfolgreiche Softwareentwicklung. Gerade in Teams mit Quereinsteigern, erfahrenen Informatikern und Neueinsteigern kommt es häufig entlang von Generationsfolgen verschiedener Softwarekonzepte und Programmiersprachen zu Vorurteilen, die den Arbeitserfolg behindern oder gar vereiteln. Durch gegenseitige Vorurteile werden Kontakte und der Erfahrungsaustausch im Team nicht gefördert. Als Folge tritt in vielen Unternehmen tendenziell eine Trennung der verschiedenen Softwareteams nach Altersgruppen auf.Die Autoren untersuchen die Gründe dieser Entwicklung. Sie entwickeln Konzepte zur Verbesserung der Teamstruktur und damit zu einer Optimierung des Softwareentwicklungsprozesses im Unternehmen.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Deutsch.

Buch. Condizione: Neu. Neuware -Modern cryptography depends heavily on number theory, with primality test ing, factoring, discrete logarithms (indices), and elliptic curves being perhaps the most prominent subject areas. Since my own graduate study had empha sized probability theory, statistics, and real analysis, when I started work ing in cryptography around 1970, I found myself swimming in an unknown, murky sea. I thus know from personal experience how inaccessible number theory can be to the uninitiated. Thank you for your efforts to case the transition for a new generation of cryptographers. Thank you also for helping Ralph Merkle receive the credit he deserves. Diffie, Rivest, Shamir, Adleman and I had the good luck to get expedited review of our papers, so that they appeared before Merkle's seminal contribu tion. Your noting his early submission date and referring to what has come to be called 'Diffie-Hellman key exchange' as it should, 'Diffie-Hellman-Merkle key exchange', is greatly appreciated. It has been gratifying to see how cryptography and number theory have helped each other over the last twenty-five years. :'-Jumber theory has been the source of numerous clever ideas for implementing cryptographic systems and protocols while cryptography has been helpful in getting funding for this area which has sometimes been called 'the queen of mathematics' because of its seeming lack of real world applications.

Taschenbuch. Condizione: Neu. Neuware -This book investigates bargaining between two agents. Its objective is to present, to extend, and to apply the present state of theoretical knowledge. A wide range of questions will be considered: First of all, will two parties reach efficient agreements Traditional economic theory gives a generally affirma tive answer for perfectly rational agents, who can carry out complex calcu lations instantaneously and without cost. The book uses innovative methods to analyse the implications of less demanding assumptions. A practical ques tion related to bargaining is: How much power does the design of institutions such as the U. N. Security Council give to each of its members Formally, non permanent members' votes are necessary to pass resolutions, but theoretical investigation of pre-voting negotiation attributes all power to the five perma nent members. Or one may ask whether a society should rather finance the education in higher mathematics for a talented person than remedial training for a retarded person Different concepts of justice yield different answers. Which particular concept is implemented in a given society is also a matter of bargaining, and it is of special philosophical interest to investigate which bargain will be struck in an ideal society in which individual talents and resources are not yet known. Very generally, a bilateral bargaining situation is characterized by two agents - individuals, firms, governments, etc.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -1 Einleitung und Grundlagen 1.1 Einleitung Explodierende Kosten im Gesundheitswesen sind eines der größten volkswirt schaftlichen Probleme in allen westlichen Ländern. Steigende Nachfrage nach medizinischen Leistungen und budgetierte Ausgaben stehen einander gegenüber. Besonders stark sind neue Technologien diesem Spannungsfeld ausgesetzt, da sie von großem Nutzen für die betroffenen Patientengruppen sind, jedoch zur glei chen Zeit zusätzliche, häufig hohe Kosten verursachen. Um die optimale Vertei lung der begrenzten Mittel im Gesundheitswesen sicherzustellen, sind gesund heitsökonomische Analysen notwendig, in denen Kosten und Nutzen verschiede ner Behandlungsmethoden miteinander verglichen werden, z.B. konventionelle Behandlungen mit neuen Therapieformen. Cochlea-Implantate (CI) gehören zu den Therapien, die auf einer neuen Tech nologie beruhen und mit denen seit Anfang der siebziger Jahre taube oder ertaubte Patienten behandelt werden. Dabei wird durch die Implantation einer Elektrode ins Innenohr die direkte Reizung des Hörnervs ermöglicht, so dass resthörigen und tauben Patienten, die nicht oder nicht ausreichend von konventionellen Hörgeräten profitieren können, das Verstehen von Sprache ermöglicht wird (Lenarz, 1998 (2».Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 112 pp. Deutsch.

Buch. Condizione: Neu. Neuware -Deregulation, privatization and internationalization of the telecommunications industry has brought about enormous changes within both the European and world economy. The dynamics of the Internet and the recent wave of innovations in the telecommunications and computer industry have given rise to new opportunities for entrepreneurship, employment and growth. No doubt, the dynamics and imperfections of today`s information markets raise crucial challenges for Western Europe. The changing patterns of innovation in the digital economy have forced governments to consider new strategies to promote innovation, network effects and growth. In response to these developments this text presents new approaches to macroeconomic modelling, growth theory and trade analysis. Still further, the deregulation policies of OECD-countries are analyzed. An indispensible text for academics and professionals who want to deepen their knowledge of how the New Economy revolution continues to change the economy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Buch. Condizione: Neu. Neuware -The strong productivity growth of the US and Scandinavian countries in Europe in the 1990s has raised the question whether the ICT sector - information and com munication technology (that is computers plus telecommunications plus digital services)-is the new driving engine of high growth in leading OECD countries. Judging by the empirical evidence for the US, including a new study by McKinsey which gives mixed evidence, it is still too early to clearly dismiss Robert G. Gordon's hypothesis that the acceleration of US output growth is (dis regarding quality problems of price measurement) exclusively due to cyclical factors and increased productivity growth in the computer sector. The counter hypothesis is associated with research by Stiroh and others who argue that there are positive productivity spillover effects from ICT to other sectors. Indeed, it is not clear ex ante whether mainly the Old Economy or the so-called New Economy stands to benefit most from high innovation rates and strong productivity shifts associated with the spreading of digital services. Interestingly, the increased eco nomic role of the internet also contributes to the internationalization of the econ omy since more services have become tradable, and growing import competition itself could stimulate productivity growth and thus contribute to higher growth. If ICT plays a key role in the new economy, there are important implications in the differential degree to which Germany and the US have implemented ICT.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 368 pp. Englisch.

The reader will learn not only about the theory of quark-gluon plasmas but also how they are obtained in the laboratory through heavy-ion collisions or where they can be found in astrophysical objects such as compact stars. The book fills a gap between well-known textbook material and the research literature and is thus perfectly suited for postgraduate students who wish to enter this field, for lecturers looking for advanced material for their courses and for scientists in search of a modern source of reference on these topics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Global environmental change occupies a central niche in the pantheon of modern sciences. There is an urgent need to know and understand the way in which global biogeochemical cycles have changed over different time scales in the past and are likely to do so in the future. Equally important, it is necessary to determine the extent to which natural variability and that induce by anthropogenic activities are bringing about change. A number of international co-operative scientific programmes ad dress these issues. Chief among them are the International Geosphere-Biosphere Programme (IGBP), the World Climate Research Programme (WCRP) and the Inter national Human Dimensions Programme (IHDP) for global change. This book is one of a series of IGBP syntheses drawing together findings in global environmental change over the past decade or so. One focus of IGBP activities is the System for Analysis, Research and Training (START). Co-sponsored by the WCRP and IHDP, START establishes regional research networks for global change science in developing countries, stimulates and carries out global change research in developing regions of the world, and builds capacity to undertake such research at personal, institutional and regional levels. Several regional global change networks have been established, and much regional research has been accomplished in the last five years or so. In this book, work relating to four of the older START regions, Southern Africa, South Asia, Southeast Asia and East Asia, will be used as case studies to illustrate regional-global linkages in Earth System Science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Condizione: Neu. Neuware -Our daily lives can be maintained by the high-technology systems. Computer systems are typical examples of such systems. We can enjoy our modern lives by using many computer systems. Much more importantly, we have to maintain such systems without failure, but cannot predict when such systems will fail and how to fix such systems without delay. A stochastic process is a set of outcomes of a random experiment indexed by time, and is one of the key tools needed to analyze the future behavior quantitatively. Reliability and maintainability technologies are of great interest and importance to the maintenance of such systems. Many mathematical models have been and will be proposed to describe reliability and maintainability systems by using the stochastic processes. The theme of this book is 'Stochastic Models in Reliability and Main tainability. ' This book consists of 12 chapters on the theme above from the different viewpoints of stochastic modeling. Chapter 1 is devoted to 'Renewal Processes,' under which classical renewal theory is surveyed and computa tional methods are described. Chapter 2 discusses 'Stochastic Orders,' and in it some definitions and concepts on stochastic orders are described and ag ing properties can be characterized by stochastic orders. Chapter 3 is devoted to 'Classical Maintenance Models,' under which the so-called age, block and other replacement models are surveyed. Chapter 4 discusses 'Modeling Plant Maintenance,' describing how maintenance practice can be carried out for plant maintenance.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book focuses on the internal fixation of long bones by using intramedullary locked nails in a closed technique. Intramedullary fixation fulfils the biological requirements for fracture healing and minimises surgical trauma. Locked nails provide a favourable mechanical environment for fracture stabilisation and post-operative rehabilitation. It illustrates the use and relevance of this technique in orthopaedic and trauma surgery including reconstructive surgery, covering the basic scientific principles of reaming and locking as well as basic and advanced surgical techniques. Prevention of complications and complication management are discussed in detail. An international board of editors and authors stand for expertise in the different subspecialties of the topic. Comprehensive information is thus provided enabling the reader to reliably use the techniques described.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 176 pp. Englisch.

Buch. Condizione: Neu. Neuware -Rigorous presentation of Mathematical Homogenization Theory is the subject of numerous publications. This book, however, is intended to fill the gap in the analytical and numerical performance of the corresponding asymptotic analysis of the static and dynamic behaviors of heterogenous systems. Numerous concrete applications to composite media, heterogeneous plates and shells are considered. A lot of details, numerical results for cell problem solutions, calculations of high-order terms of asymptotic expansions, boundary layer analysis etc., are included.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.
