Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The same factors that motivated the writing of our first volume of strategic activities on fractals continued to encourage the assembly of additional activities for this second volume. Fractals provide a setting wherein students can enjoy hands-on experiences that involve important mathematical content connected to a wide range of physical and social phenomena. The striking graphic images, unexpected geometric properties, and fascinating numerical processes offer unparalleled opportunity for enthusiastic student inquiry. Students sense the vigor present in the growing and highly integrative discipline of fractal geom etry as they are introduced to mathematical developments that have occurred during the last half of the twentieth century. Few branches of mathematics and computer science offer such a contem porary portrayal of the wonderment available in careful analysis, in the amazing dialogue between numeric and geometric processes, and in the energetic interaction between mathematics and other disciplines. Fractals continue to supply an uncommon setting for animated teaching and learn ing activities that focus upon fundamental mathematical concepts, connections, problem-solving techniques, and many other major topics of elementary and advanced mathematics. It remains our hope that, through this second volume of strategic activities, readers will find their enjoyment of mathematics heightened and their appreciation for the dynamics of the world in creased. We want experiences with fractals to enliven curiosity and to stretch the imagination. 204 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since heavily non-linear and/or very complex processes stillpose a problem for automatic control, they can often behandled easily by human operators. The book describes results from ten years of research on learning control loopswhich imitate these abilities. After discussing the differencesto adaptive control some background on human information processing and behaviour is put forward and some learning control loop structure related to these ideas is shown.The ability to learn is due to memories, which are able tointerpolate for multi-dimensional input spaces between scattered output values. A neuronally and mathematically inspired memory lay out-are compared and it is shown that theylearn much faster thanbackpropagation neural networkswhich can also be used. For the learning control loop different architectures are given. Their usefulness is demonstrated by simulation and results from applications to real pilot plants. The book should be of interest for control engineers as well as researchers in neural net applicationsand/or artificial intelligence. The usual mathematical background of engineers is sufficient. 228 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Sun, wind and water draining from the land interact with the morphological features of a water body to create the environment experienced by freshwater plants and animals. The result of this interaction can be considered as the freshwater hydro climate and this plays the same role as that of conventional climate in terrestrial ecology. Agriculture, for example, has long been supported by specialist meteorological services which not only provide farmers with a sound interpretation of weather and climate without excessive technicality but which also consider relations between climate and the growth of crops and stock. There is a need for a similar service in freshwater ecology and applied biology. This book is the result of a number of years devoted to developing part of that service. It concentrates on the influence of all forms of water movement on the ecology of fresh waters. Water movement implies interest in both the quantity of water moving through river basins which reflects the climate of the catch ment as well as the nature of the fluid motion within the rivers and lakes of the basin. The book is not so much a review of recent research as an attempt to establish a logic-how knowledge of water movement can contribute to understanding the ecology of fresh waters. Two points follow directly. 300 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This paper combines data on production, on processing and formulating, on application, on the waste stream and on the possibilities for recycling polyvinyl chloride insofar as such data has relevance for an assessment of environmental impact. It is intended to help place the PVC debate on a factually well-founded basis. The paper describes many, but not all facets of the environmental effects of a common plastic. This book is based on work carried out at the Fraunhofer Institute for Systems Technology and Innovations Research and particularly on a report drawn up on the order of the Research Centre Julich (Gaensslen, H. , Sordo, M. , TOtsch, W. : Production, Processing and Recycling of PVC. Order Number 011/41072711/930, April 1989). We would like to express our thanks to Dr. Kollmann of KFA Julich for placement of this order. This book would not have come into being but for the assistance given by many colleagues. Magdalena Sordo carried out valuable preliminary work which forms the basis of many parts of the book. We would like to thank the following as representatives of our other colleagues: Eberhard BOhm for proof reading, Gunther Heger for the data base researches and Joachim Waibel for producing the illustrations. The book has been translated by H. P. Kaufmann, Technical Translations, Marketing & Advisory Services, London. We are especially grateful to Harold M. Clayton and his colleagues at Hydro Polymers Ltd for proof-reading the English manuscript. vii Contents Preface 1. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The four chapters of this volume, written by prominent workers in the field of adaptive processing and linear prediction, address a variety of problems, ranging from adaptive source coding to autoregressive spectral estimation. The first chapter, by T.C. Butash and L.D. Davisson, formulates the performance of an adaptive linear predictor in a series of theorems, with and without the Gaussian assumption, under the hypothesis that its coefficients are derived from either the (single) observation sequence to be predicted (dependent case) or a second, statistically independent realisation (independent case). The contribution by H.V. Poor reviews three recently developed general methodologies for designing signal predictors under nonclassical operating conditions, namely the robust predictor, the high-speed Levinson modeling, and the approximate conditional mean nonlinear predictor. W. Wax presents the key concepts and techniques for detecting, localizing and beamforming multiple narrowband sources by passive sensor arrays. Special coding algorithms and techniques based on the use of linear prediction now permit high-quality voice reproduction at remorably low bit rates. The paper by A. Gersho reviews some of the main ideas underlying the algorithms of major interest today. 212 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The behaviour under iteration of unimodal maps of aninterval, such as the logistic map, has recently attractedconsiderable attention. It is not so widely known that asubstantial theory has by now been built up for arbitrarycontinuous maps of an interval. The purpose of the book isto give a clear account of this subject, with completeproofs of many strong, general properties. In a number ofcases these have previously been difficult of access. Theanalogous theory for maps of a circle is also surveyed.Although most of the results were unknown thirty years ago,the book will be intelligible to anyone who has mastered afirst course in real analysis. Thus the book will be of usenot only to students and researchers, but will also providemathematicians generally with an understanding of how simplesystems can exhibit chaotic behaviour. 260 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume provides a systematic introduction to the theory of the multidimensional Mellin transformation in a distributional setting. In contrast to the classical texts on the Mellin and Laplace transformations, this work concentrates on the local properties of the Mellin transforms, i.e. on those properties of the Mellin transforms of distributions u which are preserved under multiplication of u by cut-off functions (of various types). The main part of the book is devoted to the local study of regularity of solutions to linear Fuchsian partial differential operators on a corner, which demonstrates the appearance of non-discrete asymptotic expansions (at the vertex) and of resurgence effects in the spirit of J. Ecalle. The book constitutes a part of a program to use the Mellin transformation as a link between the theory of second micro-localization, resurgence theory and the theory of the generalized Borel transformation. Chapter I contains the basic theorems and definitions of the theory of distributions and Fourier transformations which are used in the succeeding chapters. This material includes proofs which are partially transformed into exercises with hints. Chapter II presents a systematic treatment of the Mellin transform in several dimensions. Chapter III is devoted to Fuchsian-type singular differential equations. For researchers and graduate students interested in differential equations and integral transforms. This book can also be recommended as a graduate text for students of mathematics and engineering. 240 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume provides an account of the current state of the theory of combinatory spaces and discusses various applications. Here the term `combinatory space' can be regarded as a system for functional programming, and bears no close connection with combinatory logic. The main text is divided into three chapters. Chapter 1 deals with computational structures and computability; Chapter 2 considers combinatory spaces; and Chapter 3 embraces computability in iterative combinatory spaces. A number of appendices treat a survey of examples of combinatory spaces. All sections of the various chapters contain exercices togethers with hints for solution where appropriate. For the reading of some parts of the book a knowledge of mathematical logic and recursive function theory would be desirable. For researchers and specialists in mathematical logic and its applications and theoretical computer scientists. 342 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -When agency or intentional causation has occurred the theory presented here identifies an object ascribable to the agent -- his action -- which, through its properties, reveals its intentional cause. Such a unified view of agency and action leads to unitary views of intention and the intentional and of all explanatory objects ascribable to agents. While at odds in these matters with the prevailing theories of action, the semantics of this explanatory theory is shown to better satisfy widely accepted criteria for a viable theory of action. The revelatory character of action and its essential reference to agency shows that action theory needs agency theory. To this end, a logic of practical rational agency is developed which is intended to be neutral between competing theories of mind. A sketch of this model of agency and action, analyzes cases of agency in natural discourse. PRAGMA and its manual are available separately. This work is of interest to theorists concerned with the fundamental practical rational structure of persons, their actions and the discourse appropriate to them: to philosophers and to political, legal, AI and economic theorists. 228 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At the date of this writing, there is no question that the boundary element method has emerged as one of the major revolutions on the engineering science of computational mechanics. The emergence of the technique from relative obscurity to a cutting edge engineering analysis tool in the short space of basically a ten to fifteen year time span is unparalleled since the advent of the finite element method. At the recent international conference BEM XI, well over one hundred papers were presented and many were pub lished in three hard-bound volumes. The exponential increase in interest in the subject is comparable to that shown in the early days of finite elements. The diversity of appli cations of BEM, the broad base of interested parties, and the ever-increasing presence of the computer as an engineering tool are probably the reasons for the upsurge in pop ularity of BEM among researchers and industrial practitioners. Only in the past few years has the BEM audience become large enough that we have seen the development of specialty books on specific applications of the boundary element method. The present text is one such book. In this work, we have attempted to present a self-contained treatment of the analysis of physical phenomena governed by equations containing biharmonic operators. The biharmonic operator defines a very important class of fourth-order PDE problems which includes deflections of beams and thin plates, and creeping flow of viscous fluids. 268 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is not a textbook. Instead, it contains what the author judges necessary to cope with questions relating to Gross Anatomy in board and licensure exami nations. Although material that has appeared recently on (Part I) National Board Examinations is covered, simply listing and answering such questions certainly would not prepare you for the myriad possible alternatives. Because of your suc cessful background in anatomy, the approaches used in a first-year course are not necessary here. Recall, review and synthesis are the goals. Please examine the entire book now, to understand its organization and content, and how they may serve your needs. Throughout, text is kept to a minimum. The style, size and boldness of type were chosen to aid the quick recognition of import items. The illustrations, es sentially adaptations from blackboard drawings used by the author in reviews, support the text in certain areas. However, the number of illustrations sufficient to make this an independent resource would defeat our purpose. I assume you will consult your favorite atlas as you review, and that you are experienced enough now to relate your reading to your own body. A general table of contents follows this preface; detailed tables of content precede individual chapters. 184 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of the summer school 'Modern Methods of Optimization', held at the Schlof3 Thurnau of the University of Bayreuth, October 1-6, 1990. Like other branches of applied mathematics the area of optimization is undergoing a rapid development since the beginning of the computer age. Optimizaiton methods are of increasing importance for both, science and industry. The aim of the summer school was to present state-of-the-art knowledge by inviting 12 specialists from Op timization (and related fields) to present their areas of activity in the form of survey talks. This volume contains 10 of these presentations in slightly extended form. Most lectures started from an undergraduate level and outlinad the developments up to the latest scientifique achievements. This enabled the audience, consisting of about 45 students and young researchers, to get an excellent overview of the latest trends in Optimization as w~ll as a grasp of the breadth of its potential applications. Equally important to the success of the summer school was the 'nonmeasurable' part of the activities inherent in such a summer school. Here the inspiring atmosphere of a place like Thurnau helped to establish numerous contacts between 'teachers' and 'students'. The summer school was organized by the Universitii. t Bayreuth together with the Technische Hochschule Darmstadt and was generously sponsored by the Volkswagen stiftung and the Universitii. tsverein Bayreuth. Their interest in the meeting and their support is hereby gratefully acknowledged. 364 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The book is concerned with the problems of dynamic systemscontrol in conditions of uncertainty caused by the lack ofadequate a priori data on control objects' properties. Itsspecial feature is the use of a priori estimates of indeter-mined quantities on the form of sets. A unique method of ad-aptive control systems construction is described. A con-structional algorithm for solving parametric identificationproblems is suggested which allows guaranteed estimate to bereceived in the form of some set. The application of gameapproach tothe statement and solution of control synthesisproblems under the conditions of uncertainty has allowed toreduce the problem to the minimax one. The appearance offurther unimprovable estimates causes the necessity to refu-se the use of adaptive control and to turn to the robustcontrol. Because of this, much attention is being given tothe problem of the robust stability and synthesis of robustcontrol. The book isintended for specialists concerend withthe investigation and design of control systems who haveknowledge in mathematics within the courses for hightechnical schools. 220 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Biological Sciences are in the midst of a scientific rev olution. During the past decade under the rubric of molecu lar biology, chemistry and physics have assumed an integral role in biological research. This is especially true in ge netics, where the cloning of genes and the manipulation of genomic DNA have become in many organisms routine laboratory procedures. These noteworthy advances, it must be empha sized, especially in molecular genetics, are not autonomous. Rather, they have been accomplished with those organisms whose formal genetics has been documented in great detail. For the beginning student or the established investigator who is interested in pursuing eukaryote molecular genetic re search, Drosophila melanogaster, with its rich body of formal genetic information is one organism of choice. The book 'Drosophila Genetics. A Practical Course' is an indispens able source of information for the beginner in the biology and formal genetics of Drosophila melanogaster. The scope of this guide, a revision and enlargement of the original German language version, is broad and instructive. The information included ranges from the simple, but necessary, details on how to culture and manipulate Drosophila flies to a series of more sophisticated genetic experiments. After completing the experiments detailed in the text, all students - neophyte or experienced - will be richly rewarded by having acquired a broad base of classical genetics information relevant for the biologist in its own right and prerequisite to Drosophila genetics research - formal and/or molecular.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Closely geared to general practice yet without neglecting basic theory, this book has retained so much appeal among readers .as to warrant a third edition. We assume that the work has retained its place among the leading publications on psychosomatics because it embodies our strong interest in the 'here and now' of medical practice. The timing of this thoroughly revised and enlarged edition appears opportune as psychosomatic basic care and the medicine of dialogue acquire more meaning in daily routine practice, and as the need for basic information increases. We conceive psychosomatics to be an integral part of medicine. When we speak of 'psychosomatic disorders' in this book, our premise is that somatic and psychosocial aspects play an important role in their pathogenesis and course. This notion constitutes the very basis of what is understood as psychosomatic medical treatment. Such a point of departure calls for a consistent spirit of cooperation with regard to the problems involved. This alone satisfies the initial requirement of simultaneously considering both the somatic and psychosocial aspects of health and illness. 268 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Diabetes Guide adopts a novel, non-textual approach in order to present comprehensive, up-to-date information on the theory and practice of diabetology. Tables, diagrams, flowsheets, summaries and annotations take the place of the usual prose and verbiage. As a result, vast amounts of knowledge on the definition, classification, management, complications and various other aspects of diabetes have been condensed into a surprisingly digestible pocketbook. An outstanding feature of the Diabetes Guide is the provision of succinct, practical recommendations for solving problems that arise during the daily care of patients with diabetes. The subjects covered under these recommendations cover a wide range: insulin infuser pump problems, the care of foot ulcers, food exchanges, travel and acute illness, insulin allergy and desensitization protocol, diabetic emergencies, pregnancy, surgery, hypoglycaemia, etc. Emerging perspectives on genetic counseling, the insulin gene and pancreatic transplantation are also incorporated. Such breadth of coverage without the usual price of increased bulk has been made possible by the unique non-textual approach. The Diabetes Guide is truly a user-friendly, ready reference or vade mecum with practical tips and core information about diabetes. 140 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Measurement of Image Velocity presents a computational framework for computing motion information from sequences of images. Its specific goal is the measurement of image velocity (or optical flow), the projection of 3-D object motion onto the 2-D image plane. The formulation of the problem emphasizes the geometric and photometric properties of image formation, and the occurrence of multiple image velocities caused, for example, by specular reflections, shadows, or transparency. The method proposed for measuring image velocity is based on the phase behavior in the output of velocity-tuned filters. Extensive experimental work is used to show that phase can be a reliable source of pure image translation, small geometric deformation, smooth contrast variations, and multiple local velocities. Extensive theorectical analysis is used to explain the robustness of phase with respect to deviations from image translation, and to detect situations in which phase becomes unstable. The results indicate that optical flow may be extracted reliably for computing egomotion and structure from motion. The monograph also contains a review of other techniques and frequency analysis applied to image sequences, and it discusses the closely related topics of zero-crossing tracking, gradient-based methods, and the measurement of binocular disparity. The work is relevant to those studying machine vision and visual perception. 222 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although I feel honored to write a foreword for this important book, it is a task that I approach with some trepidation. The topics covered in the book summarize the current state of the art in technical demography. However, my knowledge and expertise with respect to technical demography are limited to the most fundamental and intermediate-level methods; hence, critical commentary on the contents of this volume is beyond my scope in this fore word. Since I have some understanding of the logic and substantive aspects of the methods rather than the complicated mathematics used in describing them, my comments will necessarily be restricted to the book's general or ganization and content. To date, most texts published on technical demography have been limited to traditional demographic methods: sources and limitations of data, life table construction and applications, standardization techniques, various methods for preparing population estimates and forecasts, etc. However, population specialists have in recent years been developing and successfully applying a variety of sophisticated techniques not covered in the more standard intro ductory texts. In addition, many traditional methods that are unique to the demographic discipline have been improved and extended. 244 pp. Englisch.
