Buch. Condizione: Neu. Neuware - The original, Dutch version of this book served in 1979 as a doctoral disserta tion in philosophy at the Free University in Amsterdam. In this preface to the - slightly revised - English translation, I wish once again to express my gratitude to my supervisors, Prof. J. van der Hoeven of the Free University and Prof. G. Nuchelmans of the University of Leiden, for their excellent and stimulating support. Professor van der Hoeven was associated with this project from the outset. It was a privilege to benefit from his incisive commentaries, especially in those instances where the objective was to break through to more fundamental insights. I shall not lightly forget his friendly and heartening encouragement. I am equally grateful for my discussions with Professor Nuchelmans. I almost always tried to follow his advice, since it was based upon awesome expertness and erudition. I am happy to have found in the person of Herbert Donald Morton, Th.M., M.A., an able and enthusiastic translator. Drs. Gerben Groenewoud made the translations of a number of the Latin citations. I acknowledge permission from Routledge and Kegan Paul and the University of Toronto Press to quote from The Collected Works of John Stuart Mill. And I thank the Netherlands Organization for the Advancement of Pure Research (Z.W.O.) for fmancing this translation.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The increasing power and decreasing price of smalI computers, especialIy 'personal' computers, has made them increasingly popular in statistical analysis. The day may not be too far off when every statistician has on his or her desktop computing power on a par with the large mainframe computers of 15 or 20 years ago. These same factors make it relatively easy to acquire and manipulate large quantities of data, and statisticians can expect a corresponding increase in the size of the datasets that they must analyze. Unfortunately, because of constraints imposed by architecture, size or price, these smalI computers do not possess the main memory of their large cousins. Thus, there is a growing need for algorithms that are sufficiently economical of space to permit statistical analysis on smalI computers. One area of analysis where there is a need for algorithms that are economical of space is in the fitting of linear models. 208 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume of Lecture Notes in Statistics consists of the published proceedings of the first international conference to be held on the topic of generalised linear models. This conference was held from 13 - 15 September 1982 at the Polytechnic of North London and marked an important stage in the development and expansion of the GLIM system. The range of the new system, tentatively named Prism, is here outlined by Bob Baker. Further sections of the volume are devoted to more detailed descriptions of the new facilities, including information on the two different numerical methods now available. Most of the data analyses in this volume are carried out using the GLIM system but this is, of course, not necessary. There are other ways of analysing generalised linear models and Peter Green here discusses the many attractive features of APL, including its ability to analyse generalised linear models. Later sections of the volume cover other invited and contributed papers on the theory and application of generalised linear models. Included amongst these is a paper by Murray Aitkin, proposing a unified approach to statistical modelling through direct likelihood inference, and a paper by Daryl Pregibon showing how GLIM can be programmed to carry out score tests. A paper by Joe Whittaker extends the recent discussion of the relationship between conditional independence and log-linear models and John Hinde considers the introduction of an independent random variable into a linear model to allow for unexplained variation in Poisson data. 200 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph is principally the work of the late Martin Norr. He completed a draft of the entire monograph but had not yet revised it when he died in late 1972. At that time, the integration of corporate and shareholder taxation was just beginning to become of widespread interest in the United States. With the increasing interest thereafter, the International Tax Program began to revise his manuscript, making as few changes as possible in the original draft. We had the benefit of criticism and analysis from Professor Richard M. Bird of the University of Toronto, now Director of the Institute of Policy Analysis there. In addition, Mr. Mitsuo Sato of the Ministry of Finance in Japan gave freely of his time in carefully suggesting changes throughout the manuscript. The present version of Chapter 3 owes a great deal to his additions and suggestions. Thanks are also due to Professor Hugh J. Ault of Boston College Law School for the Appendix, containing his description of the German integration system that became effective in 1977, which was first published in Law & Policy in International Business. Mr. Norr's interest in the subject of corporate and shareholder taxation developed while he was writing the International Tax Program's World Tax Series volume Taxation in France, published in 1966. The integration of French taxes on corporations and shareholders took place just after that volume was finished, but had been under discussion in France for some time before then. 228 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Nuclear ftedicine is not and has not been a purely imaging discipline. It is function analysis that has always been the focal pOint. This fact has become particularly obvious in the last few years through the employment of nev short-lived radionuclides, new technical procedures and data processing. The disadvantage of function analysis in Inclear ftedicine through the use of radioactively labeled compounds is that more and more complicated and expensive equipment his to be used. A further characteristic is that these machines are stationary, and that the patients cannot be examined under physiological conditions. For technical reasons the x-camera is developing in the direction of mea suring mainly the so-ca~led 'soft' I-emitters at the present time. On the other hand, positron emitters are the radionuclides which are of interest for metabolic functions. At present, positron cameras are even more e~pensive and complicated machines, the use of which is very demanding. In this book Priv. -Doz. Dr. med. Dipl. -Ing. D. Peter pretschner has described a new system which contains his ideas and his technical developments. He describes a solution to the urgent questions and dif ficulties in the employment of radioactive substances for diagnosis. It does not demand large resources and can be used under the appropri ate individual physiological conditions. Here he was helped by his training as a natural scientist and engineer, as well as by his being an experienced clinician. 148 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an introduction to a range of methods and techniques used in the scientific study of the rocks, soils, atmosphere, waters and living organisms of the Earth, and of the relationships of these environmental factors with human activities. It is intended to provide a selection of methods for students taking university courses in geography, geology, meteorology, hydrology, soil science, ecology and other allied environmental sciences. The contributors are all members of the School of Environmental Sciences at the University of East Anglia, Norwich, UK, and the book has developed from part of our course for first year students. It reflects our belief that students of vast complex environmental systems should begin their work with a panoramic view, whatever their ultimate specialization. The emphasis is therefore on breadth of treatment and on the connections between the various sciences. We have summarized and simplified in order to supply a collection of methods that can be managed by a beginning student. We start from basic principles and do not assume that the reader already has a strong scientific background. Eleven chapters follow, each dealing with a group of closely related methods and techniques. They may be taken in any order, although there are many cross references which demonstrate that the subjects covered are not eleven isolated techniques but a web of related principles. The first three topics illustrate the point. 416 pp. Englisch.

Bolton Group Ltd, Director 0/ Sealink Ltd and a past President o/the General Council 0/ British Shipping The shipping industry has always lacked a body which can confer professional status on would-be practitioners: in that sense, unlike those closely allied to his responsibilities - the marine engineer, the shipowner or manager is obliged to remain an unqualified amateur. The latest addition to Mr Branch's list of titles goes a long way towards correcting this position: a proper study of the material in his book would clearly go far to confer the status of 'complete ship operator' upon anyone who was examined on its contents. Know ledge as comprehensive as that acquired through Mr Branch's book must provide a sound base on which to build the experience of practice.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Biochemical tests of fetal well-being ('placental function tests') have been part of routine obstetric practice for more than twenty years. This book provides an overview of the current status of these tests - the physiological basis for their use, and their advantages and limitations in clinical practice. Considerable attention is given to interpretation, a subject which in the past has led to much confusion both in the scientific literature and in the minds of clinicians. Recent advances are described in detail, in particular the discovery of a whole new generation of placental products some of which offer great promise in the prediction of conditions, such as placental abruption and premature labour, which cannot be identified by any other current parameters. Finally, a set of clear recommendations is put forward for the choice of test in most of the common complications of both early and late pregnancy. The emphasis throughout is on how the basic biology of fetoplacental products dictates their use and interpretation in pathological conditions. 108 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is the result of our teaching in the last few years of a first year graduate course on multivariable feedback systems addressed to control engineers. The prerequisites are modest: an undergraduate course in control (for acquaintance with concepts, terms, and design goals) and a senior-graduate course in linear systems. This volume covers lumped linear time-invariant multi-input multi-output systems with strong emphasis on control problems. The purpose is to provide a rapid introduction to some of the main and simpler results of control theory and to provide access to the current literature. Note that our exposition pays particular attention to the time-domain behavior of the systems under study. Note also that we cover neither optimization nor stochastic systems since these topics are treated in separate courses. As is obvious from its abundant literature, multivariable control is a very rapidly developing field. Consequently, we have no expectation that our exposition will become definitive; however, we hope that our efforts will be found useful. To get an idea of the contents, we suggest reading carefully the table of contents and the introduction of the chapters. Roughly, Chapter 1 is an introduction to feedback issues in a multivariable context (desensitization, large gain, singular values, etc. ). Chapters 2 and 3 cover the mathematical tools for handling transfer functions as polynomial-matrix fractions and for studying systems described by polynomial matrices. Chapter 4 uses these tools to cover the general theory of interconnected systems. 288 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -For several decades botanists have been impressed by the discovery that the distribution of secondary plant substances follows the general lines of plant relationships. However, it soon became clear that little was to be gained from the study of individual compounds and their natural distribu tion. Therefore, more comprehensive studies were attempt ed in which the secondary chemistry of a major plant group was carefully studied and evaluated in the broader context of comparative phytochemistry. Holger Erdtman's admir able work on Coniferae is the foremost example of this kind. Since then, there has been an upswing in the study of the biosynthesis of secondary plant substances and it has become quite customary to make use of biosynthetic knowledge in interpreting chemosystematic evidence. More over, since taxonomists have insisted that use be made of all potentially available evidence for building classifications, it has been claimed that chemosystematics too should con sider the whole array of constituents present in a major taxon. However, in practice it has proved difficult to utilize fully the potential of natural product chemistry and biosynthetic studies for plant systematics and evolution, because bota nists found themselves rather disorientated by the scattered, often hardly accessible chemical literature and the fact that the chemical evidence was difficult for them to evaluate!
