Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book, the new and rapidly expanding field of scientific computing is understood in a double sense: as computing for scientific and engineering problems and as the science of doing such computations. Thus scientific computing touches at one side mathematical modelling (in the various fields of applications) and at the other side computer science. As soon as the mathematical models de scribe the features of real life processes in sufficient detail, the associated computations tend to be large scale. As a consequence, interest more and more focusses on such numerical methods that can be expected to cope with large scale computational problems. Moreover, given the algorithms which are known to be efficient on a tradi tional computer, the question of implementation on modern supercomputers may get crucial. The present book is the proceedings of a meeting on 'Large Scale Scientific Computing' , that was held a t the Oberwolfach Mathematical Institute (July 14-19, 1985) under the auspices of the Sonderforschungsbereich 123 of the University of Heidelberg. Participants included applied scientists with computational interests, numerical analysts, and experts on modern parallel computers. 'l'he purpose of the meeting was to establish a common under standing of recent issues in scientific computing, especially in view of large scale problems. Fields of applications, which have been covered, included semi-conductor design, chemical combustion, flow through porous media, climatology, seismology, fluid dynami. cs, tomography, rheology, hydro power plant optimization, subwil. y control, space technology. 404 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Least squares is probably the best known method for fitting linear models and by far the most widely used. Surprisingly, the discrete L 1 analogue, least absolute deviations (LAD) seems to have been considered first. Possibly the LAD criterion was forced into the background because of the com putational difficulties associated with it. Recently there has been a resurgence of interest in LAD. It was spurred on by work that has resulted in efficient al gorithms for obtaining LAD fits. Another stimulus came from robust statistics. LAD estimates resist undue effects from a feyv, large errors. Therefore. in addition to being robust, they also make good starting points for other iterative, robust procedures. The LAD criterion has great utility. LAD fits are optimal for linear regressions where the errors are double exponential. However they also have excellent properties well outside this narrow context. In addition they are useful in other linear situations such as time series and multivariate data analysis. Finally, LAD fitting embodies a set of ideas that is important in linear optimization theory and numerical analysis. viii PREFACE In this monograph we will present a unified treatment of the role of LAD techniques in several domains. Some of the material has appeared in recent journal papers and some of it is new. This presentation is organized in the following way. There are three parts, one for Theory, one for Applicatior.s and one for Algorithms. 368 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The second volume of the series on inorganic biochemistry and bio physics is singularly devoted to magnetic resonance on systems of high molecular complexity. Recently, there have been important advances in magnetic resonance studies of polymers; these advances touch on all aspects of magnetic resonance, both theoretical and applied. Particular emphasis is placed here on multipulse experiments. We believe such an report will be of considerable interest to the readers of our series owing to the importance of magnetic resonance techniques in the investigation of biopolymers. Ivano Bertini Harry Gray Series Editors Preface This book is a record of the Proceedings of the International Symposium on 'Advanced Magnetic Resonance Techniques in Systems of High Molecular Complexity', which was held in Siena between 15 and 18 May 1985. The idea of the meeting is due to Proff. N.M. Atherton, G. Giacometti and E. Tiezzi with the aim of honouring the scientific personality of Prof. S.I. Weissman. The meeting has been organized with the assistance of a National Committee formed by R. Basosi, I. Bertini, P. Bucci, C. Corvaia, A. Gamba, G. Martini, G.F. Pedulli, P.A. Temussi, and C.A. Veracini. The invited lecturers responded enthusiastically and a comprehensive picture of the theoretical and practical aspects of magnetic resonance could be therefore provided. The book contains all the plenary lectures delivered during the meeting and also a wide selection among the huge amount of contributions collected by the organizers. 528 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Disorder is one of the predominant topics in science today. The present text is devoted to the mathematical studyofsome particular cases ofdisordered systems. It deals with waves in disordered media. To understand the significance of the influence of disorder, let us start by describing the propagation of waves in a sufficiently ordered or regular environment. That they do in fact propagate is a basic experience that is verified by our senses; we hear sound (acoustic waves) see (electromagnetic waves) and use the fact that electromagnetic waves travel long distances in many aspects ofour daily lives. The discovery that disorder can suppress the transport properties of a medium is oneof the fundamental findings of physics. In its most prominent practical application, the semiconductor, it has revolutionized the technical progress in the past century. A lot of what we see in the world today depends on that relatively young device. The basic phenomenon of wave propagation in disordered media is called a metal-insulator transition: a disordered medium can exhibit good transport prop erties for waves ofrelatively high energy (like a metal) and suppress the propaga tion of waves of low energy (like an insulator). Here we are actually talking about quantum mechanical wave functions that are used to describe electronic transport properties. To give an initial idea of why such a phenomenon could occur, we have to recall that in physical theories waves are represented by solutions to certain partial differential equations. These equations link time derivatives to spatial derivatives. 188 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Tbe task of defining the aerothermodynamic environment for a vehicle flying through the air at hypersonic speeds offers diverse challenges to the designer. He must integrate a wide variety of scientific and technical disciplines, blending mathematical modeling, computational methods, and experimental measurements. Many of the manned reentry vehicles are relatively blunt or fly at very high angles of attack (so that the drag is relatively large) and enter the atmosphere at a relatively low entry angle. As a result, the hypersonic deceleration occurs at very high altitudes. Because the conversion of kinetic energy to internal energy modes occurs in a low density environment, the flow-field chemistry is an im portant consideration. Experiments on the U. S. Space Shuttle demonstrated the importance of nonequilibrium flow and surface catalycity on the heating to the vehicle. To determine the aerothermodynamic environment of other vehicles op erating hypersonically at very high altitudes, e. g. , the Aero-Assisted Space Transfer Vehicle, the designer may have to consider viscous/inviscid interactions and the modeling of noncontinuum flows. Configurations that have a relatively high ballistic coefficient (such as slender reentry vehicles) and reenter the atmosphere at relatively high angles of attack experience severe heating rates and high dynamic pressures, but only for a short period of time. For these vehicles, continuum flow models incorporating equi librium chemistry are reasonable. 560 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I received my first introduction to the brain sciences in 1936 and 1937, for me the second and third years of the 7-year medical school curriculum at the University of Leiden. During those years my interest in the subject was aroused in particular by the brilliant lectures of the physiologist G. C. Rademaker - a prominent former member of the Rudolf Magnus school - and the neurohistologist S. T. Bok, noted especially for his histometric studies of the cerebral cortex. Fascinated as I was by everything I learned about the brain from these outstanding teachers, toward the end of their courses I began to notice conspicuous gaps that separated neurophysiology from neuroanatomy. In fact, I could (or thought I could) detect a reasonable concordance between the two sciences only in case of some sensory and somatic-motor systems. For most other functions anatomical substrates seemed either poorly defined or, as in the case of the central viscero-endocrine system, hardly recognized at all. With all the arrogance of which a 20-year old student is capable I concluded that what the brain sciences needed was a new and more complete anatomy that emphasized in particular the continuity of, and convergences or interconnections between individual conduction systems. And I wistfully mused that perhaps at some time in the future I could make such an endeavour part of my own career. 640 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The TGF-13 superfamily is a large and expanding multigene family which in verte brates includes the TGF-13 proteins themselves, the bone morphogenetic proteins (BMPs), the growth and differentiation factors (GDF), the activins/inhibins (INH), Mullerian inhibitory substance (MIS), glial derived neurotropic factor (GDNF) and more recently macrophage inhibitory cytokine 1 (MIC-1). They are characterised by conserved structural elements and a broad commonality of function. Major structural elements All members of the TGF-13 superfamily contain as their major structural hallmark a conserved spacing and distribution of seven cysteine residues. This structure is known as the cysteine knot and tethers together regions of the peptide as well as binding the two chains of the dimer to each other. High resolution structures are now available on proteins from three families within this group including glial derived neurotropic factor (GDNF), BMP-7 and several of the TGF-13s. Despite low similarity between some of these proteins (eg, TGF-13s and GDNF are only 13% identical) they share a strikingly similar three dimensional conformation (Fig. 1). These structural elements imbue the protein with some of its familial characteristics. These include its physico-chemical stability due to tight tethering of portions of the peptide chain via criss-crossing disulphide bonds. Much of its surfaces are coated with hydrophobic patches leading to a propensity to bind non-specifically to other proteins as well as to its self. This also causes a marked propensity for aggregation when the recombinant protein is present at high concentration. 220 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is based on a one year course of lectures on structural sta bility of differential equations which the author has given for the past several years at the Department of Mathematics and Mechanics at the University of Leningrad. The theory of structural stability has been developed intensively over the last 25 years. This theory is now a vast domain of mathematics, having close relations to the classical qualitative theory of differential equations, to differential topology, and to the analysis on manifolds. Evidently it is impossible to present a complete and detailed account of all fundamental results of the theory during a one year course. So the purpose of the course of lectures (and also the purpose of this book) was more modest. The author was going to give an introduction to the language of the theory of structural stability, to formulate its principal results, and to introduce the students (and also the readers of the book) to some of the main methods of this theory. One can select two principal aspects of modern theory of structural stability (of course there are some conventions attached to this state ment). The first one, let us call it the 'geometric' aspect, deals mainly with the description of the picture of trajectories of a system; and the second, let us say the 'analytic' one, has in its centre the method for solving functional equations to find invariant manifolds, conjugating homeomorphisms, and so forth. 204 pp. Englisch.…

In the last thirty years it owes very much to the scientific pre-eminence of Ennio De Giorgi, Professor of Mathemati cal Analysis at the Scuola Normale Superiore di Pisa. His fundamental theorems in Calculus of Variations, in Minimal Surfaces Theory, in Partial Differential Equations, in Axiomatic Set Theory as well as the fertility of his mind to discover both general mathematical structures and techniques which frame many different problems, and profound and meaningful examples which show the limits of a theory and give origin to new results and theories, makes him an absolute reference point for all Italian mathematicians, and a well-known and valued personage in the international mathematical world. We have been students of Ennio de Giorgi. Now, we are glad to present to him, together with all his collegues, friends and former students, these Essays of Mathematical Analysis written in his hon our on the occasion of his sixtieth birthday (February 8th, 1988), with our best wishes and our thanks for all he gave in the past and will give us in the future.

If such a career is to be achieved by seientists in developing countries where the faeilities are not easily available, even more dedication is required. Dr. K. M. Sivanandaiah, having completed a successful career in the field of peptide chemistry, is such a seientist. Being weIl aware of the limited research facilities available in India, we are extraordinarily appreciative of Professor Sivanandaiah's dedication to the advancement of science. As a Professor of Chemistry and, until his retirement in 1992, the Head of the Department of Studies in Chemistry at Bangalore University, India, he not only devoted much of his time to his students, teaching basic organic chemistry, but was also able to contribute to the field of peptide chemistry. After completing 25 years of service at Central College, Bangalore, where he was admired as an outstanding teacher, Professor Sivanandaiah is still active in research. He is now Professor Emeritus and continues to contribute to the field of peptides. As former students of Professor Sivanandaiah, we felt that publishing a book containing articles related to the design, synthesis, conformation, and biological activity of peptides and written by eminent scientists in the field of peptide research would be a fitting tribute to his role in the field of bioorganic chemistry. 328 pp. Englisch.…

The subjects can be grouped into the following areas: Phys ical environments, configuration requirements, propulsion systems (including airbreathing systems), experimental methods for external and internal flow, theoretical and numerical methods. Since hyper sonic flight requires highly integrated systems, the Short Courses not only aimed to give in-depth analysis of hypersonic research and technology but also tried to broaden the view of attendees to give them the ability to understand the complex problem of hypersonic flight. Most of the participants in the Short Courses prepared a docu ment based on their presentation for reproduction in the three vol umes. Some authors spent considerable time and energy going well beyond their oral presentation to provide a quality assessment of the state of the art in their area of expertise as of 1989 and 1991. 284 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Der Lebensnerv aller intellektuellen und wissenschaftlichen Bestrebungen ist der ständige Zustrom wichtiger, ungelöster, aber im Prinzip lösbarer Probleme. Die projektive Geometrie zum Beispiel war früher eine blühende Ecke im mathemati schen Garten. Heute jedoch ist sie nicht mehr modern - einfach weil die Quelle wichtiger Probleme vor etwa hundert Jahren versiegte. Für die heute so populäre Chaostheorie dagegen interessierte sich vor einigen Jahrzehnten nur eine Handvoll weitsichtiger Abenteurer und Kenner des mathematisch Geheimnisvollen, bevor in jüngerer Zeit die Arbeiten von Lorenz, Smale, Feigenbaum, Yorke, May, Rössler und vielen anderen eine Fülle von Problemen aufwarfen, mit denen sich heutzutage die Chaologen, ihre Studenten und ihre Mitläufer beschäftigen. Diese Beispiele illustrieren deutlich George P6lyas wohlbekannte These, die Mathematik sei die Kunst des Problemlösens. Aber im Gegensatz zu Wissenschaftlern aus anderen Disziplinen benutzen die Mathematiker einen speziellen Ausdruck für die Lösung ihrer Probleme: Bei ihnen heißt er Theorem. Die Mathematik handelt von Theoremen: wie man auf sie kommt, wie man sie beweist, wie man sie verallgemeinert, wie man sie anwendet und wie man sie versteht. Die großen Fünfmöchte dem Leser die Mathematik näherbringen, indem es fünf der wichtigsten Errungenschaften der Mathematik unseres Jahrhunderts vorstellt. In diesem Buch werden Sie einige der größten Probleme, die die Mathe matik gelöst hat, kennenlernen. Ich möchte Ihnen zeigen, wie sie gelöst wurden, und vor allem, warum die Lösungen von Bedeutung sind - und dies nicht nur für Mathematiker. Die großen Fünfwilllehrreich und unterhaltsam sein; das Buch will Mathematik anhand von Beispielen und nicht von Lehrbuchsätzen vermitteln. 218 pp. Deutsch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In 1994 Peter Shor [65] published a factoring algorithm for a quantum computer that finds the prime factors of a composite integer N more efficiently than is possible with the known algorithms for a classical com puter. Since the difficulty of the factoring problem is crucial for the se curity of a public key encryption system, interest (and funding) in quan tum computing and quantum computation suddenly blossomed. Quan tum computing had arrived. The study of the role of quantum mechanics in the theory of computa tion seems to have begun in the early 1980s with the publications of Paul Benioff [6]' [7] who considered a quantum mechanical model of computers and the computation process. A related question was discussed shortly thereafter by Richard Feynman [35] who began from a different perspec tive by asking what kind of computer should be used to simulate physics. His analysis led him to the belief that with a suitable class of 'quantum machines' one could imitate any quantum system. 156 pp. Englisch.…
