Taschenbuch. Zustand: Neu. Neuware -Many mathematics books suffer from schizophrenia, and this is yet another. On the one hand it tries to be a reference for the basic results on flat riemannian manifolds. On the other hand it attempts to be a textbook which can be used for a second year graduate course. My aim was to keep the second personality dominant, but the reference persona kept breaking out especially at the end of sections in the form of remarks that contain more advanced material. To satisfy this reference persona, I'll begin by telling you a little about the subject matter of the book, and then I'll talk about the textbook aspect. A flat riemannian manifold is a space in which you can talk about geometry (e. g. distance, angle, curvature, 'straight lines,' etc. ) and, in addition, the geometry is locally the one we all know and love, namely euclidean geometry. This means that near any point of this space one can introduce coordinates so that with respect to these coordinates, the rules of euclidean geometry hold. These coordinates are not valid in the entire space, so you can't conclude the space is euclidean space itself. In this book we are mainly concerned with compact flat riemannian manifolds, and unless we say otherwise, we use the term 'flat manifold' to mean 'compact flat riemannian manifold. ' It turns out that the most important invariant for flat manifolds is the fundamental group.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Zustand: Neu. Neuware -Ronald L. Cohen Justice is a central moral standard in social life. It is invoked in judging individual persons and in judging the basic structure of societies. It has been described as akin to a 'human hunger or thirst' (Pascal, Pensees, cited in Hirschman, 1982, p. 91), 'more powerful than any physical hunger, and endlessly resilient' (Pitkin, 1981, p. 349). The most prominent contemporary theory of justice proceeds from the claim that justice is 'the first virtue of social institutions, as truth is systems of thought' (Rawls, 1971, p. 3). However, as the following chapters demonstrate, justice has a complex and controversial history. If, as has been claimed, justice is a central category of human thought and a central aspect of human motivation, can it also be the case that to invoke justice is no more than 'banging on the table: an emotional expression which turns one's demand into an absolute postulate' (Ross, 1959, p. 274) If justice is the first virtue of social institutions, can the concept of social or economic justice at the same time be 'entirely empty and meaningless' so that any attempt to employ it is 'either thoughtless or fraudulent' (Hayek, 1976, pp. xi-xii) In a formal sense, justice concerns ensuring that each person receives what she or he is due.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Zustand: Neu. Neuware -The key contribution of the approach to x-ray mammographic image analysis developed in this monograph is a representation of the non-fatty compressed breast tissue that we show can be derived from a single mammogram. The importance of the representation, called hint, is that it removes all those changes in the image that are due only to the particular imaging conditions (for example, the film speed or exposure time), leaving just the non-fatty 'interesting' tissue. Normalising images in this way enables them to be enhanced and matched, and regions in them to be classified more reliably, because unnecessary, distracting variations have been eliminated. Part I of the monograph develops a model-based approach to x-ray mammography, Part II shows how it can be put to work successfully on a range of clinically-important tasks, while Part III develops a model and exploits it for contrast-enhanced MRI mammography. The final chapter points the way forward in a number of promising areas of research. Audience: This book has been written for a wide readership, including medical image analysts, medical physicists, radiologists, breast surgeons, and research students. The mathematics and algorithms have been relegated to boxes so that the book can be read and understood even if the mathematical detail is skipped. Large parts of the monograph will be of interest to clinicians generally and to patients.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Buch. Zustand: Neu. Neuware - The subject of modelling and application of stochastic processes is too vast to be exhausted in a single volume. In this book, attention is focused on a small subset of this vast subject. The primary emphasis is on realization and approximation of stochastic systems. Recently there has been considerable interest in the stochastic realization problem, and hence, an attempt has been made here to collect in one place some of the more recent approaches and algorithms for solving the stochastic realiza tion problem. Various different approaches for realizing linear minimum-phase systems, linear nonminimum-phase systems, and bilinear systems are presented. These approaches range from time-domain methods to spectral-domain methods. An overview of the chapter contents briefly describes these approaches. Also, in most of these chapters special attention is given to the problem of developing numerically ef ficient algorithms for obtaining reduced-order (approximate) stochastic realizations. On the application side, chapters on use of Markov random fields for modelling and analyzing image signals, use of complementary models for the smoothing problem with missing data, and nonlinear estimation are included. Chapter 1 by Klein and Dickinson develops the nested orthogonal state space realization for ARMA processes. As suggested by the name, nested orthogonal realizations possess two key properties; (i) the state variables are orthogonal, and (ii) the system matrices for the (n + l)st order realization contain as their 'upper' n-th order blocks the system matrices from the n-th order realization (nesting property).

Buch. Zustand: Neu. Neuware - Biochemical Modulation at the present time defines an area of study in which the intracellular metabolism of a given anti cancer agent is modulated (usually by a noncytotoxic agent or a cytotoxic agent at sufficiently low dosage to make it non cytotoxic) in order to either increase the effectiveness of the particular agent against tumor cells or decrease its cytotox icity against normal cells. The major focus of modulation has been the agents 5-fluorouracil (FUra), arabinofuranosylcytosine (ara-C), methotrexate (MTX) and a few alkylating agents. The major thrust of the studies has been to increase the flow of the anticancer agent along the pathway responsible for the formation of the cytotoxic species: for example, FUra to FUTP or ara-C to ara-CTP. While in most cases the application of research re sults to clinical trials does not require the subsequent exper tise of the laboratory researchers, application of biochemical modulatory schemes to clinical protocols necessitate a dramatic break with the past procedures. As shown in the laboratory clinical loop below, close collaboration between the laboratory and clinical investigator is essential. While the laboratory REDEFINE TECHNOLOGY, TESTS OR QUESTIONS FOR FURTHER THERAPEUTIC ADVANCE CLINICAL EXPERIMENTAL PROTOCOL (LABORATORY) RESEARCH STUDIES DEFINE AND TEST APPROPRIATE SCIENTIFIC PARAMETERS results define rationally-based regimens, it is essential that the clinical protocols contain the requirement that clinical material (either tumor or normal tissues) be sampled to deter mine whether the biochemical modulation being proposed is in fact beinq accomplished.
