Taschenbuch. Etat : Neu. Neuware -This book examines the geometrical notion of orthogonality, and shows how to use it as the primitive concept on which to base a metric structure in affine geometry. The subject has a long history, and an extensive literature, but whatever novelty there may be in the study presented here comes from its focus on geometries hav ing lines that are self-orthogonal, or even singular (orthogonal to all lines). The most significant examples concern four-dimensional special-relativistic spacetime (Minkowskian geometry), and its var ious sub-geometries, and these will be prominent throughout. But the project is intended as an exercise in the foundations of geome try that does not presume a knowledge of physics, and so, in order to provide the appropriate intuitive background, an initial chapter has been included that gives a description of the different types of line (timelike, spacelike, lightlike) that occur in spacetime, and the physical meaning of the orthogonality relations that hold between them. The coordinatisation of affine spaces makes use of constructions from projective geometry, including standard results about the ma trix represent ability of certain projective transformations (involu tions, polarities). I have tried to make the work sufficiently self contained that it may be used as the basis for a course at the ad vanced undergraduate level, assuming only an elementary knowledge of linear and abstract algebra.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Buch. Etat : Neu. Neuware -Since the appearance of Kobayashi's book, there have been several re sults at the basic level of hyperbolic spaces, for instance Brody's theorem, and results of Green, Kiernan, Kobayashi, Noguchi, etc. which make it worthwhile to have a systematic exposition. Although of necessity I re produce some theorems from Kobayashi, I take a different direction, with different applications in mind, so the present book does not super sede Kobayashi's. My interest in these matters stems from their relations with diophan tine geometry. Indeed, if X is a projective variety over the complex numbers, then I conjecture that X is hyperbolic if and only if X has only a finite number of rational points in every finitely generated field over the rational numbers. There are also a number of subsidiary conjectures related to this one. These conjectures are qualitative. Vojta has made quantitative conjectures by relating the Second Main Theorem of Nevan linna theory to the theory of heights, and he has conjectured bounds on heights stemming from inequalities having to do with diophantine approximations and implying both classical and modern conjectures. Noguchi has looked at the function field case and made substantial progress, after the line started by Grauert and Grauert-Reckziegel and continued by a recent paper of Riebesehl. The book is divided into three main parts: the basic complex analytic theory, differential geometric aspects, and Nevanlinna theory. Several chapters of this book are logically independent of each other.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Etat : Neu. Neuware -Elliptic functions parametrize elliptic curves, and the intermingling of the analytic and algebraic-arithmetic theory has been at the center of mathematics since the early part of the nineteenth century. The book is divided into four parts. In the first, Lang presents the general analytic theory starting from scratch. Most of this can be read by a student with a basic knowledge of complex analysis. The next part treats complex multiplication, including a discussion of Deuring's theory of l-adic and p-adic representations, and elliptic curves with singular invariants. Part three covers curves with non-integral invariants, and applies the Tate parametrization to give Serre's results on division points. The last part covers theta functions and the Kronecker Limit Formula. Also included is an appendix by Tate on algebraic formulas in arbitrary charactistic.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

Buch. Etat : Neu. Neuware -xii the evaluations, techniques, and outcome have helped to document the efficacy of their therapeutic modalities. In addition, many good books and articles have been published introducing new concepts, such as the importance of systematic case studies and personality styles by Horowitz, a variety of brief therapies by Budman, and an integrating model of time-limited psychotherapy by Strupp, to men tion only a few. The investigation of the efficacy of short-term anxiety-provoking psychotherapy (STAPP), which is the subject of this book, has con tinued during the last eight years, particularly in reference to pa tients with unresolved Oedipal conflicts. The chapter on outcome has therefore been expanded to include some of our findings. Cautious attempts have also been made to utilize focal and in novating techniques for the treatment of individuals with borderline as well as compulsive personalities. In this second edition an effort has been made to present the specific technical factors which seem to have a therapeutic effect, such as problem solving, self-understanding, and new learning, and which are utilized by the patients to solve new emotional conflicts long after the end of their treatment. Chapters on the treatment of elderly patients and the handling of individuals with physical symptomatology have been added; a history of the extensive treatment of a male patient has been pre sented to complement the discussion of the therapy of my female patient which appears in Appendix I.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Buch. Etat : Neu. Neuware -This book contains the proceedings of the International Symposium on Alternative and Advanced Automotive Engines, held in Vancouver, B.C., on August 11 and 12, 1986. The symposium was sponsored by EXPO 86 and The University of British Columbia, and was part of the specialized periods program of EXPO 86, the 1986 world's fair held in Vancouver. Some 80 attendees were drawn from 11 countries, representing the academic, auto motive and large engine communities. The purpose of the symposium was to provide a critical review of the major alternatives to the internal combustion engine. The scope of the symposium was limited to consideration of combustion engines, so that electric power, for example, was not considered. This was not a reflec tion on the possible contribution which electric propulsion may make in the future, but rather an attempt to focus the proceedings more sharply than if all possible propulsion systems had been considered. In this way all of the contributors were able to participate in the sometimes lively discussion sessions following the presentation of each paper.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Etat : Neu. Neuware -Changes and additions are sprinkled throughout. Among the significant new features are: ¿ Markov-chain simulation (Sections 1. 3, 2. 6, 3. 6, 4. 3, 5. 4. 5, and 5. 5); ¿ gradient estimation (Sections 1. 6, 2. 5, and 4. 9); ¿ better handling of asynchronous observations (Sections 3. 3 and 3. 6); ¿ radically updated treatment of indirect estimation (Section 3. 3); ¿ new section on standardized time series (Section 3. 8); ¿ better way to generate random integers (Section 6. 7. 1) and fractions (Appendix L, program UNIFL); ¿ thirty-seven new problems plus improvements of old problems. Helpful comments by Peter Glynn, Barry Nelson, Lee Schruben, and Pierre Trudeau stimulated several changes. Our new random integer routine extends ideas of Aarni Perko. Our new random fraction routine implements Pierre L'Ecuyer's recommended composite generator and provides seeds to produce disjoint streams. We thank Springer-Verlag and its late editor, Walter Kaufmann-Bilhler, for inviting us to update the book for its second edition. Working with them has been a pleasure. Denise St-Michel again contributed invaluable text-editing assistance. Preface to the First Edition Simulation means driving a model of a system with suitable inputs and observing the corresponding outputs. It is widely applied in engineering, in business, and in the physical and social sciences.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Describes fifteen years' work which has led to the construction of solutions to non-linear relativistic local field equations in 2 and 3 space-time dimensions. Gives proof ofthe existence theorem in 2 dimensions and describes manyproperties of the solutions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 560 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -The first edition appeared fourteen years ago. Since then there have been significant advances in our science that warrant an updating and revision of Sand and Sandstone. The main framework of the first edition has been retained so that the reader can begin with the mineralogy and textural properties of sands and sandstones, progress through their organization and classification and their study as a body of rock, to consideration of their origin-prove nance, transportation, deposition, and lithification-and finally to their place in the stratigraphic column and the basin. The last decade has seen the rise of facies analysis based on a closer look at the stratigraphic record and the recognition of characteristic bed ding sequences that are the signatures of some geologic process-such as a prograding shallow-water delta or the migration of a point bar on an alluvial floodplain. The environment of sand deposition is more closely determined by its place in such depositional systems than by criteria based on textural characteristics-the 'fingerprint' approach. Our revi sion reflects this change in thinking. As in the geological sciences as a whole, the concept of plate tectonics has required a rethinking of our older ideas about the origin and accumu lation of sediments-especially the nature of the sedimentary basins.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 576 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Enriched and Impoverished Environments: Effects on Brain and Behaviour is the most recent review of the active area of neuronal plasticity. The question of how experience is recorded is fundamental to psychology; speculations and investigations concerning the role of the brain in this process have entered a particularly exciting phase as of the late 1980's. Manipulations of environmental complexity is one of the earliest methods utilized in the study of neural plasticity. This monograph organizes the evidence to date concerning the responsiveness of neural and behavioural systems to external manipulation of the environment. Further consideration is given to the issues of causation of the general effects of environment on brain and behaviour. 152 pp. Englisch.

In using power series for computation the main problems are: 1) To predict a priori the number N of terms needed to do the computation with a specified accuracy; and 2) To find the coefficients aO, . ,a N These are the problems addressed in the book. Typical computations envisioned are: -6 calculate with error ~ 10 the integrals If/2 J (If/2-x)tan x dx o or the solution to the differential equation 2 y'+(sin x)Y'+x y = 0, y(O) = 0, y'(O) 1, on the interval 0 ~ x ~ 1. This computational point of view may seem narrow, but, in fact, such computations require the understa- ing and use of many of the important theorems of ele mentary analytic function theory: Cauchy's Integral Theorem, Cauchy's Inequalities, Unique Continuation, Analytic Continuation and the Monodromy Theorem, etc. The computations provide an effective motivation for learning the theorems and a sound basis for understa- ing them. To other scientists the rationale for the vi computational point of view might be the need for ef- cient accurate calculation; to mathematicians it is the motivation for learning theorems and the practice with inequalities, ~'s, o's, and N's. 144 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -And Applications To The Human-Computer Interface Michael E. Fotta AT&T Communications 16th FIr. Atrium II, Cincinnati, OH 45202 Artificial intelligence (AI) programs represent knowledge in a fashion similar to human knowledge and the activities of an AI system are closer to human behavior than that of traditional systems. Thus, AI enables the computer to act more like a human instead of making the human think and act more like a computer. This capability combined with applying human factors concepts to the interface can greatly improve the human-computer interface. This paper provides an intro duction to artificial intelligence and then proposes a number of methods for using AI to improve the human-machine inter action. AN INTRODUCTION TO ARTIFICIAL INTELLIGENCE Definition There are many definitions of artificial intelligence (AI) running from the very general to the very detailed. Perhaps the most well accepted general definition is that by Elaine Rich: 'Artificial intelligence is the study of how to make computers do things at which, at the moment, people are better', (Rich, 1983). A good example of a detailed definition is provided by the Brattle Research Corporation; 'In simplified terms, artificial intelligence works with pattern matching methods which attempt to describe objects, events or pro cesses in terms of their qualitative features and logical and compu tational relationships,' (Mishkoff, 1985). 300 pp. Englisch.
