Neuware -The main purpose of this book is to present the basic theory and some recent de velopments concerning the Cauchy problem for higher order abstract differential equations u(n)(t) + ~ AiU(i)(t) = 0, t ~ 0, { U(k)(O) = Uk, 0 ~ k ~ n-l. where AQ, Ab . . . , A - are linear operators in a topological vector space E. n 1 Many problems in nature can be modeled as (ACP ). For example, many n initial value or initial-boundary value problems for partial differential equations, stemmed from mechanics, physics, engineering, control theory, etc. , can be trans lated into this form by regarding the partial differential operators in the space variables as operators Ai (0 ~ i ~ n - 1) in some function space E and letting the boundary conditions (if any) be absorbed into the definition of the space E or of the domain of Ai (this idea of treating initial value or initial-boundary value problems was discovered independently by E. Hille and K. Yosida in the forties). The theory of (ACP ) is closely connected with many other branches of n mathematics. Therefore, the study of (ACPn) is important for both theoretical investigations and practical applications. Over the past half a century, (ACP ) has been studied extensively.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 324 pp. Englisch.

Neuware -but when we state that A 'equals' B , as well having to know what we mean by A and B we also have know what we mean by 'equals'. This section explores the role of observers; how different types of observ er see different things as being equal, and how we can produce algo rithms to decide on such equalities. It also explores how we go about writing specifications to which we may compare our SCCS designs. ¿ The final section is the one which the students like best. Once enough of SCCS is grasped to decide upon the component parts of a design, the 'turning the handle' steps of composition and check ing that the design meets its specification are both error-prone and tedious. This section introduces the concurrency work bench, which shoulders most of the burden. How you use the book is up to you; I'm not even going to suggest path ways. Individual readers know what knowledge they seek, and course leaders know which concepts they are trying to impart and in what order.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 476 pp. Englisch.

Neuware -The book, based on a course of lectures by the authors at the Indian Institute of Technology, Guwahati, covers aspects of infinite permutation groups theory and some related model-theoretic constructions. There is basic background in both group theory and the necessary model theory, and the following topics are covered: transitivity and primitivity; symmetric groups and general linear groups; wreatch products; automorphism groups of various treelike objects; model-theoretic constructions for building structures with rich automorphism groups, the structure and classification of infinite primitive Jordan groups (surveyed); applications and open problems. With many examples and exercises, the book is intended primarily for a beginning graduate student in group theory.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 220 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Purpose The purpose of this book is to explain to information technology (IT) decision makers those aspects of finance that most affect their work. Most IT decision makers belong in one of two categories. Some know a lot about IT, but less about finance; the others know a lot about finance, but less about IT. In my experience, those in the first category often have to make financial decisions. Those in the second also, of course, have to make financial decisions, but about things whose characteristics stretch the normal financial and accounting rules up to, and sometimes beyond, their elastic limit. Among the characteristics of IT that provide interesting challenges for financial people are the following: ¿ The accelerating rate of change ¿ The short and unpredictable useful life of IT assets ¿ The mixture of hardware, software and services ¿ Upgradability ¿ Networks that cross country boundaries ¿ IT jargon Asked what characteristics of finance provide interesting challenges for IT people, many of them would answer - 'Everything'. However, items in the following selection are often particular causes of wonder: ¿ Leasing ¿ Why financial models always shrink benefits but never costs ¿ Being told that a company with a mountain of profit is about to fail through lack of cash ¿ Discovering that their budget has been charged with £113 485.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 228 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -These notes are devoted to a systematic study of developing the Tomita-Takesaki theory for von Neumann algebras in unbounded operator algebras called O\*-algebras and to its applications to quantum physics. The notions of standard generalized vectors and standard weights for an O\*-algebra are introduced and they lead to a Tomita-Takesaki theory of modular automorphisms. The Tomita-Takesaki theory in O\*-algebras is applied to quantum moment problem, quantum statistical mechanics and the Wightman quantum field theory. This will be of interest to graduate students and researchers in the field of (unbounded) operator algebras and mathematical physics.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 252 pp. Englisch.

Shu and E.Tadmor at a C.I.M.E. Summer School. It is aimed at providing a comprehensive and up-to-date presentation of numerical methods which are nowadays used to solve nonlinear partial differential equations of hyperbolic type, developing shock discontinuities. The most effective methodologies in the framework of finite elements, finite differences, finite volumes spectral methods and kinetic methods, are addressed, in particular high-order shock capturing techniques, discontinuous Galerkin methods, adaptive techniques based upon a-posteriori error analysis.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 460 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -In this book we consider deep and classical results of homotopy theory like the homological Whitehead theorem, the Hurewicz theorem, the finiteness obstruction theorem of Wall, the theorems on Whitehead torsion and simple homotopy equivalences, and we characterize axiomatically the assumptions under which such results hold. This leads to a new combinatorial foundation of homology and homotopy. Numerous explicit examples and applications in various fields of topology and algebra are given.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 392 pp. Englisch.

Neuware -Caustics, Catastrophes and Wave Fields in a sense continues the treatment of the earlier volume 6 'Geometrical Optics of Inhomogeneous Media' in the present book series, by analysing caustics and their fields on the basis of modern catastrophe theory. This volume covers the key generalisations of geometrical optics related to caustic asymptotic expansions: The Lewis-Kravtsov method of standard functions, Maslov's method of caonical operators, Orlov's method of interference integrals, as well as their modifications for penumbra, space-time, random and other types of caustics. All the methods are amply illustrated by worked problems concerning relevant wave-field applications.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 232 pp. Englisch.

Neuware -On May 21-24, 1997 the Second International Symposium on Algorithms for Macromolecular Modelling was held at the Konrad Zuse Zentrum in Berlin. The event brought together computational scientists in fields like biochemistry, biophysics, physical chemistry, or statistical physics and numerical analysts as well as computer scientists working on the advancement of algorithms, for a total of over 120 participants from 19 countries. In the course of the symposium, the speakers agreed to produce a representative volume that combines survey articles and original papers (all refereed) to give an impression of the present state of the art of Molecular Dynamics.The 29 articles of the book reflect the main topics of the Berlin meeting which were i) Conformational Dynamics, ii) Thermodynamic Modelling, iii) Advanced Time-Stepping Algorithms, iv) Quantum-Classical Simulations and Fast Force Field and v) Fast Force Field Evaluation.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 516 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -There is widespread interest throughout the world in improving appliance energy efficiency. Methods to reach that end include energy labeling, energy efficiency standards and market conditioning (e.g, energy efficient procurement and DSM programs). Energy efficiency standards, which started out as an action to reduce demand for energy in individual countries, has now become a subject of regional and even worldwide dimension, particularly in the context of global climate change mitigation. Mandatory energy efficiency standards are in place for some appliances in China, Canada, Mexico, the Philippines and the United States. Standards for refrigerator/freezers will take effect in Australia and the European Union in 1999. Voluntary energy efficiency standards are in place for refrigerators in Brazil, India and Korea and for air conditioners in India, Japan and Korea. Table I showed potential global energy use reductions from codes and standards in buildings. If individual country data can be assembled, a more accurate approach to estimating potential reductions in energy use and carbon emissions would be to perform a bottom-up analysis for energy using equipment on an end-use basis in as many large developing countries as possible. The impact of standards would be assessed as more efficient appliances replaced existing stock models and new purchases that increased saturation rates were made at higher efficiencies than would otherwise be the case. This approach would show the slow but steady buildup of annual energy savings from efficiency standards or other programs to improve energy efficiency.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 648 pp. Englisch.

The interplay between randomness and computation is one of the most fas cinating scientific phenomena uncovered in the last couple of decades. This interplay is at the heart of modern cryptography and plays a fundamental role in complexity theory at large. Specifically, the interplay of randomness and computation is pivotal to several intriguing notions of probabilistic proof systems and is the focal of the computational approach to randomness. This book provides an introduction to these three, somewhat interwoven domains (i.e., cryptography, proofs and randomness). Modern Cryptography. Whereas classical cryptography was confined to the art of designing and breaking encryption schemes (or 'secrecy codes'), Modern Cryptography is concerned with the rigorous analysis of any system which should withstand malicious attempts to abuse it. We emphasize two aspects of the transition from classical to modern cryptography: ( 1) the wide ning of scope from one specific task to an utmost wide general class of tasks; and (2) the move from an engineering-art which strives on ad-hoc tricks to a scientific discipline based on rigorous approaches and techniques.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 204 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This work is concerned with a group of proteins which were originally consid ered to be an esoteric phenomenon but which have now been shown to play critical roles both in normal and stressed cells as well as being involved in a variety of human diseases. It is the purpose of this work to give a comprehen sive view of these proteins and their various aspects. After an introductory chapter providing an overview of these proteins, the work is divided into four main sections each of which deals with one important aspect of these proteins. Thus, the first section contains a series of chapters which describe individual stress proteins and their roles in particular biological phenomena. Evidently, the induction of these proteins by elevated tempera ture or other stresses is their defining feature and the second section of this book therefore considers the regulation of stress protein gene expression both by stressful stimuli such as elevated temperature or ischaemia and by non stressful stimuli such as cytokines.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 448 pp. Englisch.
