Buch. Condizione: Neu. Neuware - Decisions twenty years ago during the fIrst generation of modern traffIc safety policymaking were easier than today. Afterall, the mandate for specifIc mandatory motor vehicle safety standards was dermed rather clearly during legislative hearings. Since the initial standards, decisions have been based on the more general guidelines of 'practicality' and avoiding 'unreasonable risks. ' Now, with more diffIcult decisions pending, the demand for analysis is greater. My purpose in writing this book is to promote second generation policymaking in traffic safety. The dominant theme is that an 'individual net benefIt approach' is useful in the design, evaluation and improvement of traffic safety policy. Hopefully, this book provides some guidance for today's tougher decisions. Evaluative review of modern traffic safety policy, especially automobile safety standards, yields several results. The technological approach, the basis for the 1966 legislation, is shown to produce mistakes. Benefits are overestimated and endangerment of nonoccupants is ignored. The risk homeostatic approach, the devil's idea to some in the safety community, is shown to be a limiting case of the more general individual net benefIt approach. Rationality and competency in travelers' safety decisions are reviewed in a broad context. Evidence beyond the realm of behavioral ix x The Regulation of Motor Vehicle and Traffic Safety psychology indicates considerable, albeit imperfect, competency in traffic safety decisions. Conventional benefit-cost analysis is critiqued. Existing studies of passive restraints are shown to overestimate net benefits because travelers' responses and costs are ignored.

Buch. Condizione: Neu. Neuware - Renal stone disease remains a common clinical problem. Patients m a y attend either medical or surgical clinics and n o t infrequently present as acute abdominal emergencies to general practitioners, physicians, surgeons and even gynaecologists. Recent urinary calculi continue to cause considerable morbidity despite the recent advances in our understanding of the pathogenesis of the different types of stones involved and despite improvements in t reatment- by appropriate drug therapy, by ultrasound techniques and by lithotripsy. This volume discusses the investigation and management o f patients with calculus disease. Each chapterhas been written by a n experienced clinician and provides information of considerable relevance and importance for all doctors engaged in clinical practice. The technical developments o f the last few years have clearly demonstrated that renal stone disease, even when recurrent, should be an uncommon cause of chronic renal failure. Knowledge o f the recent developments in this field is important for all practising doctors and even more important for their patients.

Buch. Condizione: Neu. Neuware - The work presented in this text relates to research work in the general area of adaptive filter theory and practice which has been carried out at the Department of Electrical Engineering, University of Edinburgh since 1977. Much of the earlier work in the department was devoted to looking at the problems associated with the physical implementation of these structures. This text relates to research which has been undertaken since 1984 which is more involved with the theoretical development of adaptive algorithms. The text sets out to provide a coherent framework within which general adaptive algorithms for finite impulse response adaptive filters may be evaluated. It further presents one approach to the problem of finding a stable solution to the infinite impulse response adaptive filter problem. This latter objective being restricted to the communications equaliser application area. The authors are indebted to a great number of people for their help, guidance and encouragement during the course of preparing this text. We should first express our appreciation for the support given by two successive heads of department at Edinburgh, Professor J. H. Collins and Professor J. Mavor. The work reported here could not have taken place without their support and also that of many colleagues, principally Professor P. M. Grant who must share much of the responsibility for instigating this line of research at Edinburgh.

Buch. Condizione: Neu. Neuware - This book introduces a theory, Naive Semantics (NS), a theory of the knowledge underlying natural language understanding. The basic assumption of NS is that knowing what a word means is not very different from knowing anything else, so that there is no difference in form of cognitive representation between lexical semantics and ency clopedic knowledge. NS represents word meanings as commonsense knowledge, and builds no special representation language (other than elements of first-order logic). The idea of teaching computers common sense knowledge originated with McCarthy and Hayes (1969), and has been extended by a number of researchers (Hobbs and Moore, 1985, Lenat et aI, 1986). Commonsense knowledge is a set of naive beliefs, at times vague and inaccurate, about the way the world is structured. Traditionally, word meanings have been viewed as criterial, as giving truth conditions for membership in the classes words name. The theory of NS, in identifying word meanings with commonsense knowledge, sees word meanings as typical descriptions of classes of objects, rather than as criterial descriptions. Therefore, reasoning with NS represen tations is probabilistic rather than monotonic. This book is divided into two parts. Part I elaborates the theory of Naive Semantics. Chapter 1 illustrates and justifies the theory. Chapter 2 details the representation of nouns in the theory, and Chapter 4 the verbs, originally published as 'Commonsense Reasoning with Verbs' (McDowell and Dahlgren, 1987). Chapter 3 describes kind types, which are naive constraints on noun representations.

Buch. Condizione: Neu. Neuware - This volume represents the proceedings of the third in a series of annual inter national symposia. The first, The Neuroregulation of Autonomic, Endocrine, and Immune Systems, was held in Indianapolis in the fall of 1985. The second, Psychological and Biological Approaches to the Understanding of Human Disease, was held in Bielefeld, Germany in the fall of 1986. The theme of this series concerns the communication between the central nervous system and the other major systems of the body, and the purpose is to monitor the frontiers of research into these neuronal/hormonal regulatory interactions and their application to medicine. The present volume deals with the role of peptides and amino acids in these information transfer processes. Great strides have been made in exploring the important role of amino acids and pep tides in neuroregulation, and the ongoing biotechnology revolution promises signi ficant scientific and medical advances throughout the next decade and beyond. The work described in this volume captures the great excitement and pro mise of this biomedical renaissance. This meeting was cosponsored by Searle/ Monsanto and Washington University and held in St. Louis in the early fall of 1986. A major contributor to these proceedings was Dr. Thomas O'Donohue whose chapter deals with his work in characterizing the endogenous ligands for the PCP and sigma opioid receptors. Tom's personality and career personi fied the dedication of this series to the principle of a broad multidisciplinary approach to scientific problems.

The exceptions are that David Freedman and Abner Shimony were not able to contribute the papers that they presented to this volume, and that Clark Glymour who was not able to attend the conference did contribute a paper. We would like to thank the National Science Foundation and the School of Humanities of the University of California at Irvine for generous support. WILLIAM HARPER University of Western Ontario BRIAN SKYRMS University of California at Irvine Vll INTRODUCTION PART I: DECISIONS AND GAMES Causal notions have recently corne to figure prominently in discussions about rational decision making. Indeed, a relatively influential new approach to theorizing about rational choice has come to be called 'causal decision theory'. 1 Decision problems such as Newcombe's Problem and some versions of the Prisoner's Dilemma where an act counts as evidence for a desired state even though the agent knows his choice of that act cannot causally influence whether or not the state obtains have motivated causal decision theorists.

Buch. Condizione: Neu. Neuware - For the last two decades, the topic of chronic renal failure has been dominated by discussions on dialysis and transplantation. As facilities for treating patients with end-stage renal failure have become more readily available, at least in Europe and North America, attention has once again been drawn to conservative measures which may improve both the overall prognosis and the quality of life of patients with renal impairment. Although severe renal failure may be progressive and many patients will ultimately require some form of renal replacement therapy, it is now widely appreciated that distressing symptoms can often be ameliorated by judicious medical treatment. Children as well as, and perhaps to a greater extent than, adults may benefit from such therapy. This volume examines relevant trends in the conservative man agement of both adults and children with chronic renal failure. Each chapter has been written by recognized experts and provides infor mation of clinical relevance for the average clinician. As the overall prognosis for patients with end-stage renal failure improves it is clear the management of patients with relatively stable chronic renal failure is an important topic not only for nephrologists but for all practising clinicians.

Buch. Condizione: Neu. Neuware - From my B.E.E degree at the University of Minnesota and right through my S.M. degree at M.I.T., I had specialized in solid state devices and microelectronics. I made the decision to switch to computer-aided design (CAD) in 1981, only a year or so prior to the introduction of the simulated annealing algorithm by Scott Kirkpatrick, Dan Gelatt, and Mario Vecchi of the IBM Thomas 1. Watson Research Center. Because Prof. Alberto Sangiovanni-Vincentelli, my UC Berkeley advisor, had been a consultant at IBM, I re ceived a copy of the original IBM internal report on simulated annealing approximately the day of its release. Given my background in statistical mechanics and solid state physics, I was immediately impressed by this new combinatorial optimization technique. As Prof. Sangiovanni-Vincentelli had suggested I work in the areas of placement and routing, it was in these realms that I sought to explore this new algorithm. My flJ'St implementation of simulated annealing was for an island-style gate array placement problem. This work is presented in the Appendix of this book. I was quite struck by the effect of a nonzero temperature on what otherwise appears to be a random in terchange algorithm.

Buch. Condizione: Neu. Neuware - The Geo-Sciences Panel is a synonym for the Special Programme on Global Transport Mechanisms in the Geo-Sciences. This Programme is one of the special programs established by the NATO Science Committee to promote the study of a specific topic using the usual NATO structures, namely, Advanced Research Workshops, Advanced Study Institutes, Conferences, Collaborative Research Grants, Research-Studies and Lecture Visits. The aim of the Programme is to stimulate and facilitate international col laboration among scientists of the member countries in selected areas of global transport mechanisms in the Earth's atmosphere, hydrosphere, lithosphere and asthenosphere, and the interactions between these global transport processes. Created in 1982, the Geo-Sciences Panel followed the Air Sea Interactions Panel which was very successful in reviewing mechanisms at the air-sea-ice interface. Initially the Geo-Sciences Panel recognized the importance of magma chambers, ore deposits, geochemical cycles, seismic activity and hydrological studies. However, the Panel was rap idly convinced that the climate system is one of the most important sys tems in which to promote research on global transport mechanisms. Consequently, the Panel welcomed the organization of a course on Physically Based Modelling and Simulation of Climate and Climatic Change. This course was launched in Belgium in 1984 during both the Liege colloquium on Coupled Ocean-Atmosphere tlodels and the Louvain-Ia Neuve General Assembly of the European Geophysical Society. Rapidly scientists recognized that this course was timely and would be well received by the climate community, especially by junior researchers in this multi- and inter-disciplinary field.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This research monograph is an introduction to single linear differential equations (systems) with two parameters and extensions to difference equations and Stieltjes integral equations. The scope is a study of the values of the parameters for which the equation has one solution(s) having one (finitely many) zeros. The prototype is Hill's equation or Mathieu's equation. For the most part no periodicity assumptions are used and when such are made, more general notions such as almost periodic functions are introduced, extending many classical and introducing many new results. Many of the proofs in the first part are variational thus allowing for natural extensions to more general settings later. The book should be accessible to graduate students and researchers alike and the proofs are, for the most part, self-contained. 132 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Attribute Grammars have turned into one of the most fundamental formalisms of modern Computer Science. Since 1968 when Knuth introduced the basic concepts, they have been the subject of a very large amount of literature, proving the importance of the area and the broad range of its applications. The aim of the book is to put at the disposal of researchers and students, but also of engineers interested in applications, the most important definitions and results known to date in this youthful domain. This seemed best achieved by a survey including three parts: 1) A state-of-the-art review of the main results and of the most promising research directions: this part aims at being both an aid for the reader in understanding the bibliography, by presenting the results using a unified vocabulary together with numerous pointers to the literature, and also an incitement to go into further results and research areas. 2) A presentation of most of the systems dealing with Attribute Grammars: the main interest in this part lays in the presentation of the implementation choices and of the applications. This part is the 'practical' side of the book, emphasizing the point of view of 'design' which can outline the differences between a theoretical idea and the way it can be implemented. 3) A bibliography including about 600 titles on the domain, together with a thematic index enabling readers to find their way easily in accordance with their own points of interest. 248 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This research monograph focusses on a large class of variational elliptic problems with mixed boundary conditions on domains with various corner singularities, edges, polyhedral vertices, cracks, slits. In a natural functional framework (ordinary Sobolev Hilbert spaces) Fredholm and semi-Fredholm properties of induced operators are completely characterized. By specially choosing the classes of operators and domains and the functional spaces used, precise and general results may be obtained on the smoothness and asymptotics of solutions. A new type of characteristic condition is introduced which involves the spectrum of associated operator pencils and some ideals of polynomials satisfying some boundary conditions on cones. The methods involve many perturbation arguments and a new use of Mellin transform. Basic knowledge about BVP on smooth domains in Sobolev spaces is the main prerequisite to the understanding of this book. Readers interested in the general theory of corner domains will find here a new basic theory (new approaches and results) as well as a synthesis of many already known results; those who need regularity conditions and descriptions of singularities for numerical analysis will find precise statements and also a means to obtain further one in many explicit situtations. 276 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In the last few years there has been a tremendous increase in the number of Pascal courses taught at various levels in schools and universities. Also with the advances made in electronics it is possible today for the majority of people to own or have access to a microcomputer which invariably runs BASIC and Pascal. A number of Pascal implementations exist and in the last two years a new Pascal specification has emerged. This specification has now been accepted as the British Standard BS6192 (1982). This standard also forms the technical content of the proposed International Standard IS07185. In addition to a separate knowledge of electronic engineering and programming a marriage of engineering and computer science is required. The present method of teaching Pascal in the first year of electronic engineering courses is wasteful. Little, if any, benefit is derived from a course that only teaches Pascal and its use with abstract examples. What is required is continued practice in the use of Pascal to solve meaningful problems in the student's chosen discipline. The purpose of this book is to make the use of standard Pascal (BS6192) as natural a tool in solving engineering problems as possible. In order to achieve this aim, only problems in or related to electrical and elec tronic engineering are considered in this book. The many worked examples are of various degrees of difficulty ranging from a simple example to bias a transistor to programs that analyse passive RLC networks or synthesise active circuits. 180 pp. Englisch.

Experience has shown that the volume is of special value to analysts and designers of control systems in many disciplines of engineering. The first two chapters can be of great use as a textbook for subjects from the field of dynamics and control systems in university undergraduate courses, while the third chapter is intended for more detailed graduate study. Having this in mind, every section of the book ends in many solved numerical examples. This can be of great use in the continuing education and home-study of all those who are concerned with this fast-developing field.' 296 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume presents the proceedings of the 2nd VDM-Europe Symposium held in Dublin, Ireland, September 12-16, 1988. VDM, the Vienna Development Method, is a formal method for software engineering. It is being applied to an increasing number of projects by companies throughout Europe and there is an active international research programme supporting this process. 'VDM - The Way Ahead' is the second of a series of symposia sponsored by the Commission of the European Communities (CEC) and organised by VDM-Europe. The term 'formal method' refers to mathematically formal software specification and production methods. These methods aim to increase the quality of software in two related ways: by improving the specification and by making verification during the software production process more effective and easier to audit. The symposium proceedings focus on five areas of interest: education and technology transfer, experience and use of VDM, tools and support environments, method development and foundation at work, the standardisation of VDM. The proceedings are of interest to all those concerned with the application of more rigorous approaches to software development and the associated theoretical foundations. 516 pp. Englisch.

The iconography is suffieiently characteristic to be read without the help of clinical or biological data. It comprises both normal and pathologie findings. Analysis of scans is comprised of two steps. The first part consists of the detailed study of normal scans, whieh serve as a reference. For this, eight main slice levels have been considered necessary and sufficient: neces sary since a certain number of slices are indispensable for the exploration of the abdomen; sufficient because a larger number of slices would risk rendering memorization difficult. The second part involves a study of the pathologie findings, organ by organ. Acknowledgements. Appreciation is extended to all those who have helped in realizing this study and, more particularly, to our friends and colleagues, J. L. DIETEMANN, C. Roy, J. L. BURGUET, M. VOUGE, and J. W.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The statistical analysis of discrete multivariate data has received a great deal of attention in the statistics literature over the past two decades. The develop ment ofappropriate models is the common theme of books such as Cox (1970), Haberman (1974, 1978, 1979), Bishop et al. (1975), Gokhale and Kullback (1978), Upton (1978), Fienberg (1980), Plackett (1981), Agresti (1984), Goodman (1984), and Freeman (1987). The objective of our book differs from those listed above. Rather than concentrating on model building, our intention is to describe and assess the goodness-of-fit statistics used in the model verification part of the inference process. Those books that emphasize model development tend to assume that the model can be tested with one of the traditional goodness-of-fit tests 2 2 (e.g., Pearson's X or the loglikelihood ratio G ) using a chi-squared critical value. However, it is well known that this can give a poor approximation in many circumstances. This book provides the reader with a unified analysis of the traditional goodness-of-fit tests, describing their behavior and relative merits as well as introducing some new test statistics. The power-divergence family of statistics (Cressie and Read, 1984) is used to link the traditional test statistics through a single real-valued parameter, and provides a way to consolidate and extend the current fragmented literature. As a by-product of our analysis, a new 2 2 statistic emerges 'between' Pearson's X and the loglikelihood ratio G that has some valuable properties. 228 pp. Englisch.
