Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The role of Hilbert polynomials in commutative and homological algebra as well as in algebraic geometry and combinatorics is well known. A similar role in differential algebra is played by the differential dimension polynomials. The notion of differential dimension polynomial was introduced by E. Kolchin in 1964 [KoI64]' but the problems and ideas that had led to this notion (and that are reflected in this book) have essentially more long history. Actually, one can say that the differential dimension polynomial describes in exact terms the freedom degree of a dynamic system as well as the number of arbitrary constants in the general solution of a system of algebraic differential equations. The first attempts of such description were made at the end of 19th century by Jacobi [Ja890] who estimated the number of algebraically independent constants in the general solution of a system of linear ordinary differential equations. Later on, Jacobi's results were extended to some cases of nonlinear systems, but in general case the problem of such estimation (that is known as the problem of Jacobi's bound) remains open. There are some generalization of the problem of Jacobi's bound to the partial differential equations, but the results in this area are just appearing. At the beginning of the 20th century algebraic methods in the theory of differen tial equations were actively developed by F. Riquier [RiqlO] and M. 444 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Designing new structural materials, extending lifetimes and guarding against fracture in service are among the preoccupations of engineers, and to deal with these they need to have command of the mechanics of material behaviour. The first volume of this two-volume work deals with elastic and elastoplastic behaviour; this second volume continues with viscoelasticity, damage, fracture (resistance to cracking) and contact mechanics. As in Volume I, the treatment starts from the active mechanisms on the microscopic scale and develops the laws of macroscopic behaviour. Chapter I deals with viscoplastic behaviour, as shown, for example, at low temperatures by the effects of oscillatory loads and at high temperatures by creep under steady load. Chapter 2 treats damage phenomena encountered in all materials - for example, metals, polymers, glasses, concretes - such as cavitation, fatigue and stress-corrosion cracking. Chapter 3 treats those concepts of fracture mechanics that are needed for the understanding of resistance to cracking and Chapter 4 completes the volume with a survey of the main concepts of contact mechanics. As with Volume I, each chapter has a set of exercises, either with solutions or with indications of how to attack the problem; and there are many explanatory diagrams and other illustrations. 424 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is an extensive revision of a book that I wrote over ten years ago. My purpose then has remained unchanged: to introduce the concepts and methods of spatial statistics to geologists and engineers working with oil and gas data. I believe I have accomplished more than that; just as I learned the basics of variography and kriging from books for mining engineers, this book could be used by scientists from many fields to learn the basics of the subject. I have tried to adopt an introductory and practical approach to the subject, knowing that books that detail the theory are available. What I say and write comes from my own experience. As a geologist working in the public sector, I have had the privilege of using geostatistics in funded research, in answering service requests from industry, and in short courses. I have taught geostatistics in the university classroom, and advised graduate students in theses and dissertations. I have attempted to anticipate the needs and questions of the enquiring scientist because I was there myself, and know the kind of questions and concerns I had at the time I was trying to learn the subject. 252 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the courses given at the Fifth School on Complex Systems held at Santiago, Chile, from 9th .to 13th December 1996. At this school met researchers working on areas related with recent trends in Complex Systems, which include dynamical systems, cellular automata, symbolic dynamics, spatial systems, statistical physics and thermodynamics. Scientists working in these subjects come from several areas: pure and applied mathematics, physics, biology, computer science and electrical engineering. Each contribution is devoted to one of the above subjects. In most cases they are structured as surveys, presenting at the same time an original point of view about the topic and showing mostly new results. The paper of Bruno Durand presents the state of the art on the relationships between the notions of surjectivity, injectivity and reversibility in cellular automata when finite, infinite or periodic configurations are considered, also he discusses decidability problems related with the classification of cellular automata as well as global properties mentioned above. The paper of Eric Goles and Martin Matamala gives a uniform presentation of simulations of Turing machines by cellular automata. The main ingredient is the encoding function which must be fixed for all Turing machine. In this context known results are revised and new results are presented. 196 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although it took some time to establish the word, photonics is both widely accepted and used throughout the world and a major area of activity concerns nonlinear materials. In these the nonlinearity mainly arises from second-order or third-order nonlinear optical processes. A restriction is that second-order processes only occur in media that do not possess a centre of symmetry. Optical fibres, on the other hand, being made of silica glass, created by fusing SiO molecules, are made of material with a centre of z symmetry, so the bulk of all processes are governed by third-order nonlinearity. Indeed, optical fibre nonlinearities have been extensively studied for the last thirty years and can be truly hailed as a success story of nonlinear optics. In fact, the fabrication ofsuch fibres, and the exploitation oftheir nonlinearity, is in an advanced stage - not least being their capacity to sustain envelope solitons. What then ofsecond-order nonlinearity This is also well-known for its connection to second-harmonic generation. It is an immediate concern, however, to understand how waves can mix and conserve both energy and momentum ofthe photons involved. The problem is that the wave vectors cannot be made to match without a great deal of effort, or at least some clever arrangement has to be made - a special geometry, or crystal arrangement. The whole business is called phase matching and an inspection ofthe state-of-the-art today, reveals the subject to be in an advanced state. 500 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is devoted to an investigation of some important problems of mod ern filtering theory concerned with systems of 'any nature being able to per ceive, store and process an information and apply it for control and regulation'. (The above quotation is taken from the preface to [27]). Despite the fact that filtering theory is l'argely worked out (and its major issues such as the Wiener-Kolmogorov theory of optimal filtering of stationary processes and Kalman-Bucy recursive filtering theory have become classical) a development of the theory is far from complete. A great deal of recent activity in this area is observed, researchers are trying consistently to generalize famous results, extend them to more broad classes of processes, realize and justify more simple procedures for processing measurement data in order to obtain more efficient filtering algorithms. As to nonlinear filter ing, it remains much as fragmentary. Here much progress has been made by R. L. Stratonovich and his successors in the area of filtering of Markov processes. In this volume an effort is made to advance in certain of these issues. The monograph has evolved over many years, coming of age by stages. First it was an impressive job of gathering together the bulk of the impor tant contributions to estimation theory, an understanding and moderniza tion of some of its results and methods, with the intention of applying them to recursive filtering problems. 396 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many of the contributions to this volume are based on research originally presented at the historic first meeting in the United States of Japanese and American phenomenologists that took place at Seattle University in the Summer of 1991. In addition, other contributions have been added in order to supplement and complement the themes of the work presented at this meeting. Owing both to the vagaries of fate and the finitude of time, the publication of these essays has taken much longer than was originally intended. Nevertheless, this delay is more than offset by the inclusion in one volume of both phenomenological thematics and phenomenological authors who do not usually appear together. 356 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The Thirteenth International Conference on Basement Tectonics was held on the campus of Virginia Polytechnic Institute and State University in Blacksburg, Virginia from June 2 -6, 1997. The oral presentations and discussions over three days covered a wide range of topics, and provided the international audience with a perspective on scientific efforts underway around the world. The conference participants were able to attend two separate field trips: (I) a pre-conference trip guided by Professor Robert Hatcher of the University of Tennessee, Knoxville, examined the Basement rocks in the North Carolina -Tennessee region of the Appalachian Mountains, and (2) a mid-conference field trip guided by A.K. Sinha, convener of the conference, allowed participants to examine the complex rock associations and structures of the 1000 m.y. old basement rocks in Virginia. Both the field trip guid Elektronisches Buch and abstract volumes were published for the conference. The meeting brought together scientists from more than 14 countries. Their participation, and the fiscal success of the meeting would not have been possible without the support of the Department of Geological Sciences, the College of Arts and Sciences (VPI&SU) and the Basement Tectonics Association. Their support is gratefully acknowledged. As Chairman of the Organizing Committee, I would like to thank Margie Sentelle, Jay Thomas, Peter Welch, and Barry Robinson for the smooth operation of the conference. 380 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The increasing global demand for food and other agricultural products calls for urgent measures to increase water use efficiency which is, with plant nutrient availability, one of the two main limiting factors in crop production. Although only 20% of all cultivated land in the world is under irrigation, it provides 35-40% of all crop production. Because of higher yields under irrigated agriculture, investments for irrigation are usually a top priority. However, it has become a matter of serious concern in recent years that, despite their high co~ts, the performance of many irrigation projects has fallen short of expectations as a result of inadequate water management at both farm and system levels. Crop production increase has been well below the project targets. The greatest potential for increasing food and other agricultural products is the more efficient use of naturally occurring precipitation in conjunction with improved soil fertility management. Until recently, regardless of the amounts and distribution of rainfall, irrigation practices were used almost exclusively to supplement the amount of soil water stored in the root zone to such an extent that the available soil water never allowed the crop to suffer from water stress throughout the growing season. As a result, even today farmers still tend to over-irrigate to ensure a bountiful amount of water stored. 276 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Normative Social Theory James M. Dean and A. M. C. Waterman University of Manitoba 1. Economics and Religion Once Again This hook is a sequel to Economics and Religion: Are They Distinct (Brennan and Waterman 1994). That volume was motivated by a frustration born of many disappointing encounters between economists and theologians in the 1980s. Can bishops, synods, and other voices of organized religion bring any interesting (and disinterested) contribution to the public policy debate If so, what is the relation of their contribution to that of the purely 'secular' knowledge economists believe they can supply Can economists bring any interesting (and disinterested) contribution to the public policy debate If so, what is the relation of their contribution to the fundamental values that inform social ethics and that are still guarded to a large extent by religious tradition All too often the two sides talked at cross-purposes. Well-intentioned economists coexisted for a few hours or days with well intentioned theologians whose manner of conceiving social reality was radically incompatible with their own. There seemed to be no common ground. The first requisite of any genuine conversation is an agreed conceptual framework that is able to accommodate the peculiar social vision both of the economist and of theologian, and to display the logical relation between the two. 220 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The world was first introduced to the expertise and originality of Japanese scholars in phenomenology in Analecta Husserliana Vol. IX (1979). The third generation of Japanese scholars, belonging to the newly-founded Merleau-Ponty Japanese Circle, are now presented. Following Merleau-Ponty's tendency, the studies collected here seem to make a fresh phenomenological start in relation to classical Husserlian phenomenology, turning deliberately towards the `concrete', `the wild world', `flesh', `embodiment', `natural signs', `primal nature'. The rule of intentionality, natural language is thereby devalued. The wealth of insights, the freshness of intuition and the seminal power of these fascinating enquiries well merit a close reading. 268 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Multiphase systems dominate nearly every area of science and technology, and the method of volume averaging provides a rigorous foundation for the analysis of these systems. The development is based on classical continuum physics, and it provides both the spatially smoothed equations and a method of predicting the effective transport coefficients that appear in those equations. The text is based on a ten-week graduate course that has been taught for more than 20 years at the University of California at Davis and at other universities around the world. Problems dealing with both the theoretical foundations and the applications are included with each chapter, and detailed solutions for all problems are available from the author. The course has attracted participants from chemical engineering, mechanical engineering, civil engineering, hydrologic science, mathematics, chemistry and physics. 244 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this collection of essays Allan Franklin defends the view that science provides us with knowledge about the world which is based on experimental evidence and on reasoned and critical discussion. In short, he argues that science is a reasonable enterprise. He begins with detailed studies of four episodes from the history of modern physics: (1) the early attempts to detect gravity waves, (2) how the physics community decided that a proposed new elementary particle, 17-keV neutrino, did not exist, (3) a sequence of experiments on K meson decay, and (4) the origins of the Fifth Force hypothesis, a proposed modification of Newton's Law of Universal Gravitation. The case studies are then used to examine issues such as how discord between experimental results is resolved, calibration of an experimental apparatus and its legitimate use in validating an experimental result, and how experimental results provide reasonable grounds for belief in both the truth of physical theories and in the existence of the entities involved in those theories. This book is a challenge to the critics of science, both postmodern and constructivist, to provide convincing alternative explanations of the episodes and issues discussed. It should be of interest to philosophers, historians, and sociologists of science, and to scientists themselves. 332 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the most relevant peer-reviewed papers presented at The First International Workshop on Vrancea Earthquakes, held in Bucharest on November 1-4, 1997. Strong earthquakes in the Romanian Vrancea area have caused a high toll of casualties and extensive damage over the last several centuries. With a moment magnitude of 7.4, the 1977 earthquake caused more than 1500 casualties, the majority of them in Bucharest. The contributions address key problems of seismotectonics of the Vrancea area and related strong ground motion, hazard assessment, site effects and microzonation, structural damage and earthquake resistant design, risk assessment and disaster management from an international and regional perspective. This list of topics shows the diverse contributions from the multidisciplinary fields of geosciences, geophysics, seismology, geology, civil engineering, city planning, and emergency relief practices. This book is of value for scientists interested in earthquake hazard and seismic risk research as well as for seismologists, geophysicists and Earth scientists. It is also useful for authorities responsible for public safety and natural hazard mitigation plans and for insurance companies. 402 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since all-out interstate wars for the time being seem to belong to the past, con flict studies focus more and more on domestic conflicts. This is a broad field, not only because the arbitrary line between war and sub-war violence disap pears and the analyst is confronted with phenomena reaching from criminal violence and clashes between communities to violent conflicts of long duration and civil wars with massacres and genocides as their characteristics. It is also because there are so many different types of conflicts to be analyzed, so many different types of behavior to be studied, whereas there is often little informa tion available on what is really going on. Against the background of internal conflicts, which tend to be as protracted as diffuse in terms of time, intensity, actors, and their goals, this study aims to follow a specific pathway through the current thicket of violent circumstances. It focuses on causation patterns by exploring the causal role of the environ mental factor in the genesis of violent conflicts occurring today and probably even more so tomorrow. This approach, which for once does not focus on a specific level of the conflict system, on one area in the conflict geography, or on a specific category of actors, analyzes causation dynamics. 348 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Work and Idleness develops the view that redistributing employment is a `feasible capitalist' solution, not just to the unemployment which particular groups suffer, but also to the work that others have to contend with, including many women. Putting the redistribution of employment on the policy agenda opens up debate on how to ensure a more equitable and fulfilling relationship between the ways we gain our livelihoods and the lives we lead. Growing insecurity in labour markets and changing patterns in the commodification of labour have led to a redistribution of paid and unpaid labour time as the structure of power relations, the gender order, discrimination, and state regulation have been modified. The first main trend affecting insecurity is mass unemployment and the growth of workless households. A second notable trend is a gender-based redistribution of hours worked. The third major trend is a shift from full-time waged work to full-time self-employment. Part I of this book presents the main economic theories driving the continuing divide between the intensification of work and the extension of idleness. Part II documents the ways in which the shift to mass idleness in advanced industrial countries has hit some groups particularly hard: the youngest and oldest age groups and other groups, including disabled workers, have traditionally been subject to discrimination in the labor markets. Part III provides a set of policy prescriptions. 348 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rice is the major staple food in Asia, and food security means rice security for most Asians. By the year 2025, we need to produce about 60% more rice than we do today to meet the growing demand. Efficient use of inputs is vital to safely produce the additional food from limited resources with minimal impact on the environment. This book reviews emerging knowledge-intensive technologies and decision aids for improved nutrient management in rice, technology adoption constraints at the farm level, and innovative approaches for field evaluation and promotion of new technologies to farmers. It is highly useful to rice scientists and development workers, students of agronomy, soil science, and plant nutrition, and crop consultants and extension workers in rice all over the world. 380 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The 32nd European Marine Biology Symposium was held in Lysekil, Sweden on August 16-22, 1997, organised by Kristineberg Marine Research Station. The selected topics were: `Recruitment and colonisation' and `Physical and Chemical Forcing on Marine Biological Systems', partly reflecting the present research interests at Kristineberg. In this volume, recruitment and colonisation processes cover primarily the dynamics of interspecific interactions within assemblages as well as the effects of hydrodynamic variables. Both laboratory and field studies are emphasised. The contribution of papers within the topic `Physical and Chemical Forcing on Marine Biological Systems' deals with structuring effects of, for example, tides, temperatures, nutrients and hypoxia on the physiology and ecology of marine organisms. The book covers many aspects of marine life. It is our hope that the selected topics will fascinate readers and be of wide interest to students and researchers in marine biology. 396 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The basic objective of this report is to place the debate about the future of the Northern Sea Route into the larger picture of Arctic politics and the emerging agenda of the Arctic as a developing region in international society. National security and international environmental cooperation, are the objects of study employed, both separately and in various conceptual combinations, to realize this purpose. To help me in this, I was privileged to draw on the profound expertise of my highly esteemed co-authors, Professor Franklyn Griffiths at the University of Toronto and Senior Researchers at IMEMO in Moscow: Raphael Vartanov, Alexei Roginko and Alexander Kolossov. To their cooperative spirit, friendship and solid contributions to this report, ( am deeply indebted. The report is the result of multiple contributions, both in terms of substance and funding, extending far beyond the inputs of the team of authors. The professional input and thorough work 'behind the scene' done by Liv Astrid Sverdrup, Researcher at FNI at an early stage of the project, has been invaluable. Senior Consultant Kjell Moe at the Norwegian Polar Institute also provided valuable comments and improvements to the biological parts of the Introductory chapter, whilst Senior Consultant Ann Skarstad at FNI, worked wonders with the language for those of us not having English as our mother tongue.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As recent developments have shown, supersymmetric quantum field theory and string theory are intimately related, with advances in one area often shedding light on the other. The organising ideas of most of these advances are the notion of duality and the physics of higher dimensional objects or p-branes. The topics covered in the present volume include duality in field theory, in particular in supersymmetric field theory and supergravity, and in string theory. The Seiberg-Witten theory and its recent developments are also covered in detail. A large fraction of the volume is devoted to the current state of the art in M-theory, in particular its underlying superalgebra as well as its connection with superstring and N = 2 strings. The physics of D-branes and its essential role in the beautiful computation of the black hole entropy is also carefully covered. Finally, the last two sets of lectures are devoted to the exciting matrix approach to non-perturbative string theory. 508 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -When solving real-life engineering problems, linguistic information is often encountered that is frequently hard to quantify using 'classical' mathematical techniques. This linguistic information represents subjective knowledge. Through the assumptions made by the analyst when forming the mathematical model, the linguistic information is often ignored. On the other hand, a wide range of traffic and transportation engineering parameters are characterized by uncertainty, subjectivity, imprecision, and ambiguity. Human operators, dispatchers, drivers, and passengers use this subjective knowledge or linguistic information on a daily basis when making decisions. Decisions about route choice, mode of transportation, most suitable departure time, or dispatching trucks are made by drivers, passengers, or dispatchers. In each case the decision maker is a human. The environment in which a human expert (human controller) makes decisions is most often complex, making it difficult to formulate a suitable mathematical model. Thus, the development of fuzzy logic systems seems justified in such situations. In certain situations we accept linguistic information much more easily than numerical information. In the same vein, we are perfectly capable of accepting approximate numerical values and making decisions based on them. In a great number of cases we use approximate numerical values exclusively. It should be emphasized that the subjective estimates of different traffic parameters differs from dispatcher to dispatcher, driver to driver, and passenger to passenger. 412 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is not an exaggeration to say that one of the most exciting predictions of Einstein's theory of gravitation is that there may exist 'black holes': putative objects whose gravitational fields are so strong that no physical bodies or signals can break free of their pull and escape. The proof that black holes do exist, and an analysis of their properties, would have a significance going far beyond astrophysics. Indeed, what is involved is not just the discovery of yet another even if extremely remarkable, astro physical object, but a test of the correctness of our understanding of the properties of space and time in extremely strong gravitational fields. Theoretical research into the properties of black holes, and into the possible corol laries of the hypothesis that they exist, has been carried out with special vigor since the beginning of the 1970's. In addition to those specific features of black holes that are important for the interpretation of their possible astrophysical manifestations, the theory has revealed a number of unexpected characteristics of physical interactions involving black holes. By the middle of the 1980's a fairly detailed understanding had been achieved of the properties of the black holes, their possible astrophysical manifestations, and the specifics of the various physical processes involved. Even though a completely reliable detection of a black hole had not yet been made at that time, several objects among those scrutinized by astrophysicists were considered as strong candidates to be confirmed as being black holes. 796 pp. Englisch.
