Buch. Condizione: Neu. Neuware - This book presents a collection of papers which evaluate the achievements of the Australian Trade Practices Act 1974 in making Australian markets more competitive. The contributors have all played major roles in Australian and New Zealand antitrust actions, either as expert economic witnesses, as antitrust enforcers, as judges or as quasi-judicial administrators. No other publication presents such in-depth economic analysis of the Act and the cases decided under it in its first two decades of its operation. As well as an introductory paper, this collection includes a foreword by the Hon. George Gear, Assistant Treasurer of the Australian Government and Minister responsible for the administration of the Act, plus two broad analytical overviews of the last two decades of Australian antitrust actions by two economists who have continually been at the heart of antitrust proceedings. In addition, papers are provided which give a judicial view of the Act and economic analysis, which compare the Act with its New Zealand counterpart. Other contributions look in detail at those sections of the Act which cover mergers, misuse of market power, price-fixing and vertical practices. The book shows that the Act has had a major impact on Australian market behavior. Judges, lawyers and economists between them have produced a truly Australian approach to antitrust, which has reflected overseas trends in both law and economics, as well as developed a unique Australian flavor. The book will be of interest to academic and practicing lawyers and economists, judges and corporate executives. It will be essential reading for Australian students in undergraduate courses in antitrust law, business regulation, antitrust economics and industrial organization. It provides by far the most comprehensive economic evaluation of Australian antitrust yet published and so will be the definitive source of information on this topic for non-Australians interestedin comparative antitrust legislation and enforcement issues.

Buch. Condizione: Neu. Neuware - l. THE GENERAL PROBLEM OF EPISTEMOLOGY There is a philosophical issue that surely precedes all other possible questions. It concerns the very possibility of our thinking about some thing to some purpose. Short of this no philosophy, theory or research would be possible. But it is not immediately clear that we are assured that what purports to be effective thought, and cognition is such in reality. What guarantee is there for instance that when one is under the impression that one is thinking that 'the cat is on the mat' it is in fact the case that one is thinking this One could not be thinking at all, only having a misleading mystic experience. And then even if one was thinking, one might not be really thinking of the cat being on the mat, but only that one wishes there was a cat, and wonders whether if there was it would be on the mat, and yet the subjective impression was that one was thinking: 'The cat is on the mat' (the same picture might stand for both the thoughts mentioned). Then one might in some way try to think 'the cat is on the mat. ' yet be mistaken in that there aren't any material objects at all, and all one does is to inventory god's perceptions. And so on, and so on! These are of course the kind of problem that the layman habitually views with disdainful alarm.

Taschenbuch. Condizione: Neu. Neuware - The present monograph is a comprehensive summary of the research on visibility in random fields, which I have conducted with the late Professor Micha Yadin for over ten years. This research, which resulted in several published papers and technical reports (see bibliography), was motivated by some military problems, which were brought to our attention by Mr. Pete Shugart of the US Army TRADOC Systems Analysis Activity, presently called US Army TRADOC Analysis Command. The Director ofTRASANA at the time, the late Dr. Wilbur Payne, identified the problems and encouraged the support and funding of this research by the US Army. Research contracts were first administered through the Office of Naval Research, and subsequently by the Army Research Office. We are most grateful to all involved for this support and encouragement. In 1986 I administered a three-day workshop on problem solving in the area of sto chastic visibility. This workshop was held at the White Sands Missile Range facility. A set of notes with some software were written for this workshop. This workshop led to the incorporation of some of the methods discussed in the present book into the Army simulation package CASTFOREM. Several people encouraged me to extend those notes and write the present monograph on the level of those notes, so that the material will be more widely available for applications.

Buch. Condizione: Neu. Neuware - People want more from the government. One thing they want more of is a sense of personal safety, at home and at work (Regulation, Fall 1991). People also want the government to quit wasting money. The objective of having the government provide a safer life for us and our children at minimum cost leads logically to looking at policy within the system involving the private sector plus governments at the federal and sub federal levels. Using numerical simulations our book takes an integrated quantitative look at how the various institutions influencing workplace safety lead to the observed levels of illnesses and injuries among U.S. workers. Our innovation is piecing together the mosaic of interactions among workers, employers, state government, and the federal government that is numerically realistic in the sense of using economists' current knowl edge of quantitative connections. Our objective has been to write a Gray's Anatomy, if you will, of how the U.S. economic system, as tempered by government policy, jointly determines employment patterns, wages, and workplace safety levels.

Buch. Condizione: Neu. Neuware - Program synthesis is a solution to the software crisis. If we had a program that develops correct programs from specifications, then program validation and maintenance would disappear from the software life-cycle, and one could focus on the more creative tasks of specification elaboration, validation, and maintenance, because replay of program development would be less costly. This monograph describes a novel approach to Inductive Logic Programming (ILP), which cross-fertilizes logic programming and machine learning. Aiming at the synthesis of recursive logic programs only, and this from incomplete information, we take a software engineering approach that is more appropriate than a pure artificial intelligence approach. This book is suitable as a secondary text for graduate level courses in software engineering and artificial intelligence, and as a reference for practitioners of program synthesis.

Buch. Condizione: Neu. Neuware - On Optimal Interconnections for VLSI describes, from a geometric perspective, algorithms for high-performance, high-density interconnections during the global and detailed routing phases of circuit layout. First, the book addresses area minimization, with a focus on near-optimal approximation algorithms for minimum-cost Steiner routing. In addition to practical implementations of recent methods, the implications of recent results on spanning tree degree bounds and the method of Zelikovsky are discussed. Second, the book addresses delay minimization, starting with a discussion of accurate, yet algorithmically tractable, delay models. Recent minimum-delay constructions are highlighted, including provably good cost-radius tradeoffs, critical-sink routing algorithms, Elmore delay-optimal routing, graph Steiner arborescences, non-tree routing, and wiresizing. Third, the book addresses skew minimization for clock routing and prescribed-delay routing formulations. The discussion starts with early matching-based constructions and goes on to treat zero-skew routing with provably minimum wirelength, as well as planar clock routing. Finally, the book concludes with a discussion of multiple (competing) objectives, i.e., how to optimize area, delay, skew, and other objectives simultaneously. These techniques are useful when the routing instance has heterogeneous resources or is highly congested, as in FPGA routing, multi-chip packaging, and very dense layouts. Throughout the book, the emphasis is on practical algorithms and a complete self-contained development. On Optimal Interconnections for VLSI will be of use to both circuit designers (CAD tool users) as well as researchers and developers in the area of performance-driven physical design.

Buch. Condizione: Neu. Neuware - Some might ask 'Why Locke's theory of knowledge now ' Though appreciated for his social philosophy, Locke has been criticized for his work in the field of epistemology ever since the publication of the Essay. It is even as if Locke serves only as an example of how not to think. When people criticize Locke, they usually cite the hostile commen taries of Berkeley, Kant, Husserl, or Sellars. But, one might ask, are they not all so eager to show the excellence of their own epistemo logical views that they distort and underestimate Locke's thought Russell aptly noted in his History of Western Philosophy that: No one has yet succeeded in inventing a philosophy at once credible and self-consis tent. Locke aimed at credibility, and achieved it at the expense of consistency. Most of the great philosophers have done the opposite. A philosophy which is not self-consis tent cannot be wholly true, but a philosophy which is self-consistent can very well be wholly false. The most fruitful philosophies have contained glaring inconsistencies, but for that very reason have been partially true. There is no reason to suppose that a self consistent system contains more truth than one which, like Locke's, is obviously more or less wrong. (B. Russell, A History of Western Philosophy [New York: Simon and Schuster, 1945], p. 613. ) Here Russell is uncommonly charitable with Locke.

Buch. Condizione: Neu. Neuware - The origin of optical methods for fluid flow investigations appears to be nontraceable. This is no matter for surprise. After all seeing provides the most direct and common way for humans to learn about their environment. But at the same time some of the most sophisticated methods for doing measurements in fluids are also based on light and often laser light. A very large amount of material has been published in this area over the last two decades. Why then another publication Well, the field is still in a state of rapid development. It is characterised by the use of results and methods developed within very different areas like optical physics, spectroscopy, communication systems, electronics and computer science, mechanical engineering, chemical engineering and, of course, fluid dynamics. We are not aware of a book containing both introductory and more advanced material that covers the same material as presented here. The book is the result of a compilation and expansion of material presented at a summer school on Optical Diagnosticsfor Flow Processes,held at RiS0 National Laboratory and the Technical University of Denmark in September 1993. The aim of the course was to provide a solid background for understanding, evaluating, and using modem optical diagnostic methods, addressing Ph. D. students and researchers active in areas of fluid flow research. The disciplines represented by the participants ranged from atmospheric fluid dynamics to biomedicine.

Buch. Condizione: Neu. Neuware - In three volumes, a distinguished group of scholars from a variety of disciplines in the natural and social sciences, the humanities and the arts contribute essays in honor of Robert S. Cohen, on the occasion of his 70th birthday. The range of the essays, as well as their originality, and their critical and historical depth, pay tribute to the extraordinary scope of Professor Cohen's intellectual interests, as a scientist-philosopher and a humanist, and also to his engagement in the world of social and political practice. The essays presented in Physics, Philosophy, and the Scientific Community (Volume I of Essays in Honor of Robert S. Cohen) focus on philosophical and historical issues in contemporary physics: on the origins and conceptual foundations of quantum mechanics, on the reception and understanding of Bohr's and Einstein's work, on the emergence of quantum electrodynamics, and on some of the sharp philosophical and scientific issues that arise in current scientific practice (e.g. in superconductivity research). In addition, several essays deal with critical issues within the philosophy of science, both historical and contemporary: e.g. with Cartesian notions of mechanism in the philosophy of biology; with the language and logic of science - e.g. with new insights concerning the issue of a `physicalistic' language in the arguments of Neurath, Carnap and Wittgenstein; with the notion of `elementary logic'; and with rational and non-rational elements in the history of science. Two original contributions to the history of mathematics and some studies in the comparative sociology of science round off this outstanding collection.

Buch. Condizione: Neu. Neuware - Non-Destructive Testing (NDT) techniques for the inspection of industrial structural components have to be qualified in respect to the minimum performance to be achieved. The qualification schemes relate to all aspects of the tests: procedure, equipment and personnel and the qualification of inspection should be codified in Standards. Such Standards are of two main types: those that detail the methods and procedures to be used and those that define the results which must be achieved. The European Network for Inspection Qualification (ENIQ) has as its aim the creation of a European collaboration for critical studies, assessment and qualification of inspection procedures for industrial structural components. The final goal is to support international Codes and Standards bodies via technical tools, expertise and demonstrative exercises that can be sponsored and managed at the European level.

Taschenbuch. Condizione: Neu. Neuware - The problem of developing metal matrix (MCM) and metal-polymer (MPCM) composite materials is one of the most important in present day materials technology, for its solution is pivotal to the development of a number of leading technologies. The development of new fibrous and lamellar composite materials with improved physico-chemical, electrical, thermal and other properties is a springboard for qualitative scientific and technological advances not only in aerospace and shipbuilding technologies, but also in mechanical, power, electronic, electrical, radio engineering, transport, construction and other industries. The volume reviews the results of research programmes ac complished in recent years by Soviet scientists in the development of composite materials based on aluminium and magnesium matrices, polymatrix composites (composite materials) with metal and polymeric matrices reinforced with boron and carbon fibres, steel wire, fibre glass and other fillers. The volume also reviews present-day physico-chemical fundamen tals and basic principles for developing and optimizing metal matrix composites, and describes the most expedient and efficient methods of MCM and MPCM manufacturing. Special attention is devoted to the issue of manufacturing MCM structural members, and their machin ing and plastic working, as well as to coupling techniques.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book gives a self-contained introduction to the subject of asymptotic approximation for multivariate integrals for both mathematicians and applied scientists. A collection of results of the Laplace methods is given. Such methods are useful for example in reliability, statistics, theoretical physics and information theory. An important special case is the approximation of multidimensional normal integrals. Here the relation between the differential geometry of the boundary of the integration domain and the asymptotic probability content is derived. One of the most important applications of these methods is in structural reliability. Engineers working in this field will find here a complete outline of asymptotic approximation methods for failure probability integrals. 164 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The book is a fairly complete and up-to-date survey of projectivity and its generalizations in the class of Boolean algebras. Although algebra adds its own methods and questions, many of the results presented were first proved by topologists in the more general setting of (not necessarily zero-dimensional) compact spaces. An appendix demonstrates the application of advanced set-theoretic methods to the field.The intended readers are Boolean and universal algebraists. The book will also be useful for general topologists wanting to learn about kappa-metrizable spaces and related classes. The text is practically self-contained but assumes experience with the basic concepts and techniques of Boolean algebras. 220 pp. Englisch.
