Buch. Condizione: Neu. Neuware -Many problems in science, technology and engineering are posed in the form of operator equations of the first kind, with the operator and RHS approximately known. But such problems often turn out to be ill-posed, having no solution, or a non-unique solution, and/or an unstable solution. Non-existence and non-uniqueness can usually be overcome by settling for `generalised' solutions, leading to the need to develop regularising algorithms.The theory of ill-posed problems has advanced greatly since A. N. Tikhonov laid its foundations, the Russian original of this book (1990) rapidly becoming a classical monograph on the topic. The present edition has been completely updated to consider linear ill-posed problems with or without a priori constraints (non-negativity, monotonicity, convexity, etc.).Besides the theoretical material, the book also contains a FORTRAN program library.Audience: Postgraduate students of physics, mathematics, chemistry, economics, engineering. Engineers and scientists interested in data processing and the theory of ill-posed problems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Condizione: Neu. Neuware -It is hard to imagine that another elementary analysis book would contain ma terial that in some vision could qualify as being new and needed for a discipline already abundantly endowed with literature. However, to understand analysis, be ginning with the undergraduate calculus student through the sophisticated math ematically maturing graduate student, the need for examples and exercises seems to be a constant ingredient to foster deeper mathematical understanding. To a talented mathematical student, many elementary concepts seem clear on their first encounter. However, it is the belief of the authors, this understanding can be deepened with a guided set of exercises leading from the so called 'elementary' to the somewhat more 'advanced' form. Insight is instilled into the material which can be drawn upon and implemented in later development. The first year graduate student attempting to enter into a research environment begins to search for some original unsolved area within the mathematical literature. It is hard for the student to imagine that in many circumstances the advanced mathematical formulations of sophisticated problems require attacks that draw upon, what might be termed elementary techniques. However, if a student has been guided through a serious repertoire of examples and exercises, he/she should certainly see connections whenever they are encountered.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book, which has been in the making for some eighteen years, would never have begun were it not for Dr. David Dewhirst in 1976 kindly having shown the author a packet of papers in the archives of the Cambridge Obser vatories. These letters and miscellaneous papers of Fearon Fallows sparked an interest in the history of the Royal Observatory at the Cape of Good Hope which, after the diversion of producing several books on later phases of the Observatory, has finally resulted in a detailed study of the origin and first years of the Observatory's life. Publication of this book coincides with the 175th anniversary of the founding of the Royal Observatory, e.G.H. Observatories are built for the use of astronomers. They are built through astronomers, architects, engineers and contractors acting in concert (if not always in harmony). They are constructed, with whatever techniques and skills are available, from bricks, stones and mortar; but their construction may take a toll of personal relationships, patience, and flesh and blood.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Buch. Condizione: Neu. Neuware -This volume follows a Specialized Symposium on 'Mantle denudation in slow spreading ridges and in ophiolites', held at the XII EUG Meeting in Strasbourg, spring 1993. During the meeting it was felt that the contribu tions to the Symposium justified a volume presenting its main scientific achievements. The present title of the volume shows that the center of inter est has slightly shifted with respect to the initial objective: in order to under stand the processes involved in accretion taking place at oceanic ridges, it is crucial to study the interaction between uppermost mantle and lower crust. The approach favored here is that of petrological and structural analysis of oceanic rocks in present-day oceanic ridges combined with similar studies in ophiolites. Rock specimen collected by submersibles or dredge hauls in oceanic ridge environments provide a 'ground truth'. However, except for areas such as the MARK (Mid-Atlantic Ridge ne ar Kane fracture zone) where, thanks to multiple submersible dives, the local geology is known with aprecision even better than in many onshore ophiolites, mutual rela tionships between uppermost mantle and lower crust are poorly known. In contrast, onshore ophiolites provide a necessary large-scale picture built up over many years of structural and petrological mapping.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condizione: Neu. Neuware -The analytical basis of Navier-Stokes Equations in Irregular Domains is formed by coercive estimates, which enable proofs to be given of the solvability of the boundary value problems for Stokes and Navier-Stokes equations in weighted Sobolev and Hölder spaces, and the investigation of the smoothness of their solutions. This allows one to deal with the special problems that arise in the presence of edges or angular points in the plane case, at the boundary or noncompact boundaries. Such problems cannot be dealt with in any of the usual ways.Audience: Graduate students, research mathematicians and hydromechanicians whose work involves functional analysis and its applications to Navier-Stokes equations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 588 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book is based on lectures delivered at Harvard in the Spring of 1991 and at the University of Utah during the academic year 1992-93. Formally, the book assumes only general algebraic knowledge (rings, modules, groups, Lie algebras, functors etc.). It is helpful, however, to know some basics of algebraic geometry and representation theory. Each chapter begins with its own introduction, and most sections even have a short overview. The purpose of what follows is to explain the spirit of the book and how different parts are linked together without entering into details. The point of departure is the notion of the left spectrum of an associative ring, and the first natural steps of general theory of noncommutative affine, quasi-affine, and projective schemes. This material is presented in Chapter I. Further developments originated from the requirements of several important examples I tried to understand, to begin with the first Weyl algebra and the quantum plane. The book reflects these developments as I worked them out in reallife and in my lectures. In Chapter 11, we study the left spectrum and irreducible representations of a whole lot of rings which are of interest for modern mathematical physics. The dasses of rings we consider indude as special cases: quantum plane, algebra of q-differential operators, (quantum) Heisenberg and Weyl algebras, (quantum) enveloping algebra ofthe Lie algebra sl(2) , coordinate algebra of the quantum group SL(2), the twisted SL(2) of Woronowicz, so called dispin algebra and many others.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Buch. Condizione: Neu. Neuware -Potato is the fourth major staple food in the world and is still rapidly gaining importance, especially in the tropics. In May, 1994 the second international potato modelling conference was held in Wageningen, the Netherlands, as a summerschool of the C. T. de Wit Graduate School. The conference was sponsored by DLO, SCRI, SSCR, W AU and the LEB-Fund. Over 80 scientists participated, coming from 16 countries. Of each crop physiological and modelling subject, a leading scientist was requested to write a review of the most recent developments in his or her field. The reviews, with highlights from the authors' own work, are such that the physiological work described is of interest to the modeller and the modelling work to the crop physiologist. Applications of the quantitative approach are also reviewed in the concluding chapters that deal with decision support systems, breeding and agro-ecological zoning. An outstanding point of this book is that both the crop ecology and the modelling of a broad range of biotic and abiotic factors are treated by scientists representing groups which are specialized in the subject. The two related disciplines met during the conference and thus wrote the chapters with each other's interest in mind. The book highlights the limitations for potato growth and development from the viewpoints of both the crop physiologist and the crop-systems analyst. 392 pp. Englisch.

Buch. Condizione: Neu. Neuware -Considering integral transformations of Volterra type, F. Riesz and B. Sz.-Nagy no ticed in 1952 that [49]: 'The existence of such a variety of linear transformations, having the same spectrum concentrated at a single point, brings out the difficulties of characterization of linear transformations of general type by means of their spectra.' Subsequently, spectral analysis has been developed for different classes of non selfadjoint operators [6,7,14,20,21,36,44,46,54]. It was then realized that this analysis forms a natural basis for the theory of systems interacting with the environment. The success of this theory in the single operator case inspired attempts to create a general theory in the much more complicated case of several commuting operators with finite-dimensional imaginary parts. During the past 10-15 years such a theory has been developed, yielding fruitful connections with algebraic geometry and sys tem theory. Our purpose in this book is to formulate the basic problems appearing in this theory and to present its main results. It is worth noting that, in addition to the joint spectrum, the corresponding algebraic variety and its global topological characteristics play an important role in the classification of commuting operators. For the case of a pair of operators these are: 1. The corresponding algebraic curve, and especially its genus. 2. Certain classes of divisors - or certain line bundles - on this curve.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Buch. Condizione: Neu. Neuware -o. COMPARATIVE GERMANIC SYNTAX This volume contains 13 papers that were prepared for the Seventh Workshop on Comparative Germanie Syntax at the University of Stuttgart in November 1991. In defining the theme both of the workshop and of this volume, we have taken 'comparative' in 'comparative Germanic syntax' to mean that at least two languages should be analyzed and 'Germanic' to mean that at least one of these languages should be Germanic. There was no require ment as such that the research presented should be situated within the framework known as Principles and Parameters Theory (previously known as Government and Binding Theory), though it probably is no accident that this nevertheless turned out to be the case. Within this theory, it is seen as highly desirable to be able to account for several differences on the surface by deriving them from fewer under lying differences. The reason is that, in order to explain the ease with which children acquire language, it is assumed that not all knowledge of any given language is the result of learning, but that instead children already possess part of this knowledge at birth (the innate part of linguistic knowledge will obviously be the same for all human beings, and thus this theory also provides an explanation of language universals).

This item is printed on demand - it takes 3-4 days longer - Neuware -'Knowledge desires increase - it is like fire that first must be kindled by some external agent, but which will always afterward propagate itself'. Johnson, Letter to William Drummond August 13, 1776 The therapeutic effectiveness and safety of beta-adrenergic blocking drugs has been well established in patients with essential hypertension and arteriosclerotic cardiovascular disease. These drugs are useful in primary protection against cardiovascular morbidity or mortality in patients with essential hypertension and secondary protection (mor bidity and mortality in patients with myocardial infarction). Although there are mass action effects common to all of beta-adrenergic block ing agents, these agents differ in their effects on the RAS system, beta blockade, norepinephrine release, CNS effects, peripheral vas cular resistance, inotrophic effects, vasomotor effects, and effects on plasma volume. Dr. Ton J. M. Cleophas has addressed this problem of different com pounds and different strategies in the use of beta-adrenergic blockers. In Chapter 1 of this book the author deals with the problem of paradoxical pressor responses from non cardioselective beta blockade. Chapter 2 deals with a review of the literature dealing with these pressor responses which are usually thought to be mild and occur in situations of increased sympathetic activity (57 references). Chapter 3 deals with the benefi cial effects of alpha blockade in Raynaud's Syndrome, and the effect of beta blockade in counteracting the alpha blocker side effects of fluid retention and tachycardia. 100 pp. Englisch.

Neuware -This volume contains several surveys focused on the ideas of approximate solutions, well-posedness and stability of problems in scalar and vector optimization, game theory and calculus of variations. These concepts are of particular interest in many fields of mathematics. The idea of stability goes back at least to J. Hadamard who introduced it in the setting of differential equations; the concept of well-posedness for minimum problems is more recent (the mid-sixties) and originates with A.N. Tykhonov. It turns out that there are connections between the two properties in the sense that a well-posed problem which, at least in principle, is 'easy to solve', has a solution set that does not vary too much under perturbation of the data of the problem, i.e. it is 'stable'. These themes have been studied in depth for minimum problems and now we have a general picture of the related phenomena in this case. But, of course, the same concepts can be studied in other more complicated situations as, e.g. vector optimization, game theory and variational inequalities. Let us mention that in several of these new areas there is not even a unique idea of what should be called approximate solution, and the latter is at the basis of the definition of well posed problem.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

After 30 years of relative obscurity, its quantitative importance in the building and maintenance of normal tissues, the subtle strategies involved in its regulation, and its significance in the pathogenesis of diseases of major social importance are becoming clear. Moreover, because a distinct set of biological events is involved in this death, these events themselves become reason able targets for new pharmacological agents in the treatment of cancer. The articles in this volume summarize the contents of a discussion meeting held at the Royal Society on 23 and 24 February 1994. The authors are a distinguished international group from a variety of disciplines in biology and medicine and hopefully their articles will convey something of the excitement of this fast-moving field. The three organizers are enormously indebted to all the contributors for the enthusiasm with which they delivered their talks, shared in discussion, and finally committed their contributions to these printed pages. We would also like to acknowledge the gracious way in which the Royal Society hosted the meeting, and in particular Mary Manning for making it the trouble-free and enjoyable experience that it was, and Janet Clifford and Simon Gribbin for skillfully managing the editorial processing of this volume.

Neuware -The goals and content for this book are derived from three important and ongoing efforts: to advance the institution of education and to promote educational opportunities to children and youth worldwide, to promote effective assessment policies and practices that enhance sound educational practice, and to address the need to develop tests and other assessment practices in less developed countries as well as to augment and alter a number of traditional assessment practices in developed nations. These three issues provided the focus for a four-day conference that was held at St. Hugh's College, Oxford University, in June 1993. The conference theme-Test Use with Children and Youth: International Pathways to Progress-underscores the importance of addressing testing issues as efforts to improve educational opportunities for children and youth move forward. Leaders from more than seventy nations met at the United Nations sponsored World Summit for Children in 1990 to support ratification of the Convention on the Rights of the Child. Worldwide recognition that every individual has the right to develop her or his potential led to the ratification of provisions setting minimum standards for children's education.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.
