Neuware -One of the attractive features of the great classical ethologists was their readiness to ask different kinds of questions about behavior - and to do so without muddling the answers. Niko Tinbergen, for instance, was interested in the evolution of behavior. But he also had interests in the present-day sur vival value of a behavior pattern and in the mechanisms that control it from moment to moment. Broad as his interests were, he clearly separated out the problems and recognized that questions about the history, function, control, and development of behavior require distinct approaches - even though the answers to one type of question may aid in finding answers to another. The open-minded (and clear-headed) style of ethologists like Tinbergen was based on a recognition that there are diverse ways of usefully con ducting research on behavior. This consciousness has been partially sub merged in recent years by new waves of narrowly focused enthusiasm. For instance, the study of the behavior of whole animals without recourse to lower levels of analysis, and the treatment of sociobiological theories as ex planation for how individuals develop, has meant that the relatively fragile plants of neuroethology and behavioral ontogeny have almost disappeared under the flood.

Taschenbuch. Condizione: Neu. Neuware -It has long been suspected, and recently confirmed, that there is an etiologic relationship between several viruses and naturally occurring neoplasias. Virus precursors in the form of nucleic acids or antigens have consistently been associated with certain neoplasias. However, the role of these virus-specified precursors in etiology remains obscure. Recent studies of virus-associated neo plasias have led to advances in molecular techniques, which have yielded increas ingly sensitive assays for detection of virus-specific nucleic acids, and which have enabled the disruption of virus particles without concomitant loss in antigenicity of the components. These procedures have, in turn, resulted in molecular probes that allow more definitive evaluation of the host response to its virus and to the tumor cell with which the virus or its precursors are associated. Evaluations of the immune response and status of the host have provided important informa tion about carcinogenesis and the tools for seroepidemiological studies of a variety of cancers. These seroepidemiological studies have demonstrated that several human cancers, e. g. , Burkitt's lymphoma and nasopharyngeal carcinoma, are probably virus-induced, and that antibodies that are diagnostic and prog nostic for these diseases are detectable. The conclusion that feline leukemia is a disease transmitted horizontally by a virus resulted primarily from immunologi cal experiments.

Neuware -EXCEPT for chapter 8, an editorial foot-bridge across the con fused years which separate the Dutch Republic from the King dom of the Netherlands, the essays collected in this volume were originally read and discussed at meetings of Dutch and British historians held between 22 and 27 September 1969 in a number of delightful comers of Groningen and Friesland. That this con ference took place at all was due in the first instance to the initiative and organizing genius of the Instituut voor Geschiedenis of the University of Groningen: particular thanks are due to the Rector Magnificus and his colleagues of that illustrious place of learning. On behalf of those fortunate enough to take part, we also wish to place on record our deep gratitude for the benevolent assistance of the Netherlands Ministerie van Onderwijs, of the H. S. Kammingafonds and of the Groninger Universiteitsfonds. As our sub-title strives to hint, the conference papers were commissioned with a view to stimulating historical awareness of a problem which is increasingly forcing itself on the attention of contemporary statesmen, administrators, sociologists and others - indeed of all who value local character and the human scale in the age of mass communications and socialized government.

Taschenbuch. Condizione: Neu. Neuware -Statistics is of ever-increasing importance in Science and Technology and this book presents the essentials of the subject in a form suitable either as the basis of a course of lectures or to be read and/or used on its own. It assumes very little in the way of mathematical knowledge-just the ability to substitute numerically in a few simple formulae. However, some mathematical proofs are outlined or given in full to illustrate the derivation of the subject; these can be omitted without loss of understanding. The book does aim at making clear the scope and nature of those essential tests and methods that a scientist or technologist is likely to need; to this end each chapter has been divided into sections with their own subheadings and some effort has been made to make the text unambiguous (if any reader finds a misleading point anywhere I hope he will write to me about it). Also with this aim in view, the equality of probability to proportion of population is stated early, then the normal distribution and the taking of samples is discussed. This occupies the first five chapters. With the principles of these chapters understood, the student can immediately learn the significance tests of Chapter 6 and, if he needs it, the analysis of variance of Chapter 7. For some scientists this will be most of what they need. Howcver, they will be in a position to read and/or use the remaining chapters without undue difficulty.

The topic was selected for several reasons, such as the rapid progress in the genetic analysis of immunoglobulin and MHC genes and the elucidation of the mechanism of switch to different immunoglobulin classes and subclasses. The genetic advances formed a basis for discussions of problems relating to regulation of T cell subsets, mechanisms of activation and regulation of B cell differentiation and an analysis of the network hypothesis. The format of the symposium was arranged so as to include two sessions in the morning and two in the afternoon. Each session was introduced by one speaker, followed by free discussion. The intro ductory lectures are included in the proceedings. The participants summarized their contributions to the discussion in written form. In addi tion to the closed sessions, there was one open session at the Karolinska Institute with lectures by Drs. L. Hood, C. Milstein, D. Baltimore, J. Klein and B. Benacerraf, which are not included in these procee din gs. The symposium was sponsored by the Nobel Foundation and its Nobel Symposium Committee through grants from the Tercentenary Fund of the Bank of Sweden and the Knut & Alice Wallenberg Foundation. The Swedish Medical Research Council, the Swedish Cancer Society and the Swedish Ministry of Education and Cultural Affairs also made contri butions.

Neuware -Although some nations, such as Japan, have invested in aquaculture research and developed major aquaculture industries, the opportunities for similar devel opment in the United States remain largely unnoticed. In a typical recent year the United States, which claims 20% of the world's marine fisheries resources, imported seafood worth $4. 8 billion and exported $l. 3 billion. In addition to the $3. 5 billion deficit in food-fish, was another $2. 7 billion deficit for nonedible fishery products. Next to oil, fishery products constituted the second highest drain on the United States balance of payments and accounts for a significant portion of the foreign trade deficit. Furthermore, fish consumption has been increasing in North America. In response to the demand for fishery products, aquaculture managers not only have the opportunity to realize economic profit, but in doing so can make an important contribution to reducing the national debt, providing employment, and enhancing our diet. This book might be considered a farm management text for those in aquaculture. It is intended to provide an introduction to aquaculture principles and an introduction to management, including business and people management, microeconomics, and the concepts of efficiency and productivity. I hope it will bridge the gap between conservationists, the academic community, and commer cial culturists. Abundant references should enable the reader to quickly access literature on most topics germane to the management of culture systems.

Taschenbuch. Condizione: Neu. Neuware -In Part I of this report the pointwise derivation of scalar set functions is investigated, first along the lines of R. DE POSSEL (abstract derivation basis) and A. P. MORSE (blankets); later certain concrete situations (e. g. , the interval basis) are studied. The principal tool is a Vitali property, whose precise form depends on the derivation property studied. The 'halo' (defined at the beginning of Part I, Ch. IV) properties can serve to establish a Vitali property, or sometimes produce directly a derivation property. The main results established are the theorem of JESSEN-MARCINKIEWICZ-ZYGMUND (Part I, Ch. V) and the theorem of A. P. MORSE on the universal derivability of star blankets (Ch. VI) . . In Part II, points are at first discarded; the setting is somatic. It opens by treating an increasing stochastic basis with directed index sets (Th. I. 3) on which premartingales, semimartingales and martingales are defined. Convergence theorems, due largely to K. KRICKEBERG, are obtained using various types of convergence: stochastic, in the mean, in Lp-spaces, in ORLICZ spaces, and according to the order relation. We may mention in particular Th. II. 4. 7 on the stochastic convergence of a submartingale of bounded variation. To each theorem for martingales and semi-martingales there corresponds a theorem in the atomic case in the theory of cell (abstract interval) functions. The derivates concerned are global. Finally, in Ch.

Neuware -The effect of calcium antagonists on heart muscle and blood circulation is the reason that they have found widespread clinical application for a number of years. Less well known, in contrast, is the effect this group of substances has on the kidneys, both on kidney cells and the blood flow through the kidneys. This effect was the subject of a workshop we organized in Tiibingen in June 1986. Different groups studied the effects of these substances, especially in animals, on the processing of calcium by the kidney cells and on blood flow. A possible explanation is that the calcium antagonists block the influx of calcium through special cell canals, especially the cells of the distal tubule. It is necessary to test whether there is a blockade or only a reduction in the passage of calcium. Our understanding of the effect of calcium antagonists is in large part based on the results of morphologic, physiologic, and pharmacologic studies of calcium in the kidneys. The particular processes involved in nephrocalcinosis are special objects of study with regard to calcium antagonists. This book presents the results of experimental studies of the effect of calcium antagonists on nephrocalcinosis and acute renal failure after ischemia. In this context, the clinician is particularly interested in the use of calcium antagonists to protect against the kidney in urolithiasis, in acute renal failure and during kidney transplantation. The book is thus of interest to urologists and nephrologists as well as pharmacologists. biochemists, physiologists, and others in research.

Taschenbuch. Condizione: Neu. Neuware -Becoming a Food Scientist is designed as a reservoir of ideas for those beginning a graduate education in food science or beginning a professional career in the field. Although at times it may read as a how-to manual for success in graduate school, it is meant to encourage each reader to study the research process, to challenge conventional wisdom, and to develop a career path that maximizes the probability of success both in school and beyond. The author has viewed food science graduate programs through the lenses of programs at four universities and service in numerous activities with the Institute of Food Technologists. This book is thus focused on the field of food science, but it may have relevance to other scientific disciplines.The book introduces the concept of research as process in the first chapter. Subsequent chapters focus on individual unit operations of research: idea generation, problem definition, critical evaluation of the literature, method selection, experimental design, data collection, processing and analysis, and knowledge dissemination. Successful graduate students in food science must master each of these operations. The final section of the book pushes the reader beyond graduate school into its practice in the real world. Topics covered in the maturation of a food scientist include the scientific meeting, critical thinking, science and philosophy, ethics, finding and managing the literature, planning, grantsmanship, laboratory setup and management, and career development. This book should be a meaningful companion for any graduate student in the field and those transitioning from graduate school to the food science profession.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -We are well into a second age of digital information. Our information is moving from the desktop to the laptop to the 'palmtop' and up into an amorphous cloud on the Web. How can one manage both the challenges and opportunities of this new world of digital information What does the future hold This book provides an important update on the rapidly expanding field of personal information management (PIM). Part I (Always and Forever) introduces the essentials of PIM. Information is personal for many reasons. It's the information on our hard drives we couldn't bear to lose. It's the information about us that we don't want to share. It's the distracting information demanding our attention even as we try to do something else. It's the information we don't know about but need to. Through PIM, we control personal information. We integrate information into our lives in useful ways. We make it 'ours.' With basics established, Part I proceeds to explore a critical interplay between personal information 'always' at hand through mobile devices and 'forever' on the Web. How does information stay 'ours' in such a world Part II (Building Places of Our Own for Digital Information) will be available in the Summer of 2012, and will consist of the following chapters:Chapter 5. Technologies to eliminate PIM : We have seen astonishing advances in the technologies of information management -- in particular, to aid in the storing, structuring and searching of information. These technologies will certainly change the way we do PIM; will they eliminate the need for PIM altogether Chapter 6. GIM and the social fabric of PIM: We don't (and shouldn't) manage our information in isolation. Group information management (GIM) -- especially the kind practiced more informally in households and smaller project teams -- goes hand in glove with good PIM.Chapter 7. PIM by design: Methodologies, principles, questions and considerations as we seek to understand PIM better and to build PIM into our tools, techniques and training.Chapter 8. To each of us, our own.: Just as we must each be a student of our own practice of PIM, we must also be a designer of this practice. This concluding chapter looks at tips, traps and tradeoffs as we work to build a practice of PIM and 'places' of our own for personal information.Table of Contents: A New Age of Information / The Basics of PIM / Our Information, Always at Hand / Our Information, Forever on the WebSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This synthesis lecture provides a survey of work on privacy in online social networks (OSNs). This work encompasses concerns of users as well as service providers and third parties. Our goal is to approach such concerns from a computer-science perspective, and building upon existing work on privacy, security, statistical modeling and databases to provide an overview of the technical and algorithmic issues related to privacy in OSNs. We start our survey by introducing a simple OSN data model and describe common statistical-inference techniques that can be used to infer potentially sensitive information. Next, we describe some privacy definitions and privacy mechanisms for data publishing. Finally, we describe a set of recent techniques for modeling, evaluating, and managing individual users' privacy risk within the context of OSNs.

Taschenbuch. Condizione: Neu. Neuware -As an alternative to traditional client-server systems, Peer-to-Peer (P2P) systems provide major advantages in terms of scalability, autonomy and dynamic behavior of peers, and decentralization of control. Thus, they are well suited for large-scale data sharing in distributed environments. Most of the existing P2P approaches for data sharing rely on either structured networks (e.g., DHTs) for efficient indexing, or unstructured networks for ease of deployment, or some combination. However, these approaches have some limitations, such as lack of freedom for data placement in DHTs, and high latency and high network traffic in unstructured networks. To address these limitations, gossip protocols which are easy to deploy and scale well, can be exploited. In this book, we will give an overview of these different P2P techniques and architectures, discuss their trade-offs, and illustrate their use for decentralizing several large-scale data sharing applications.

Taschenbuch. Condizione: Neu. Neuware -In data publishing, the owner delegates the role of satisfying user queries to a third-party publisher. As the servers of the publisher may be untrusted or susceptible to attacks, we cannot assume that they would always process queries correctly, hence there is a need for users to authenticate their query answers. This book introduces various notions that the research community has studied for defining the correctness of a query answer. In particular, it is important to guarantee the completeness, authenticity and minimality of the answer, as well as its freshness. We present authentication mechanisms for a wide variety of queries in the context of relational and spatial databases, text retrieval, and data streams. We also explain the cryptographic protocols from which the authentication mechanisms derive their security properties.

Taschenbuch. Condizione: Neu. Neuware -This text provides an accessible, self-contained and rigorous introduction to complex analysis and differential equations. Topics covered include holomorphic functions, Fourier series, ordinary and partial differential equations.The text is divided into two parts: part one focuses on complex analysis and part two on differential equations. Each part can be read independently, so in essence this text offers two books in one. In the second part of the book, some emphasis is given to the application of complex analysis to differential equations. Half of the book consists of approximately 200 worked out problems, carefully prepared for each part of theory, plus 200 exercises of variable levels of difficulty.Tailored to any course giving the first introduction to complex analysis or differential equations, this text assumes only a basic knowledge of linear algebra and differential and integral calculus. Moreover, the large number of examples, worked out problems and exercises makes this the ideal book for independent study.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book shows amateur astronomers how to use one-shot CCD cameras, and how to get the best out of equipment that exposes all three color images at once. Because this book is specifically devoted to one-shot imaging, 'One-Shot Color Astronomical Imaging' begins by looking at all the basics - what equipment will be needed, how color imaging is done, and most importantly, what specific steps need to be followed after the one-shot color images are taken.What is one-shot color imaging Typically, astronomical cooled-chip CCD cameras record only one color at a time - rather like old-fashioned black & white cameras fitted with color filters. Three images are taken in sequence - in red, blue, and green light - and these are then merged by software in a PC to form a color image. Each of the three images must be taken separately through a suitable color filter, which means that the total exposure time for every object is more than tripled. When exposure times can run into tens of minutes or even hours for each of the three colors, this can be a major drawback for the time-pressed amateur.'One-Shot Color Astronomical Imaging' describes the most cost-effective and time-efficient way for any amateur astronomer to begin to photograph the deep-sky.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The authors cover two general topics: basic engineering economics and risk analysis in this text. Within the topic of engineering economics are discussions on the time value of money and interest relationships. These interest relationships are used to define certain project criteria that are used by engineers and project managers to select the best economic choice among several alternatives. Projects examined will include both income- and service-producing investments. The effects of escalation, inflation, and taxes on the economic analysis of alternatives are discussed. Risk analysis incorporates the concepts of probability and statistics in the evaluation of alternatives. This allows management to determine the probability of success or failure of the project. Two types of sensitivity analyses are presented. The first is referred to as the range approach while the second uses probabilistic concepts to determine a measure of the risk involved. The authors have designed the text to assist individuals to prepare to successfully complete the economics portions of the Fundamentals of Engineering Exam.Table of Contents: Introduction / Interest and the Time Value of Money / Project Evaluation Methods / Service Producing Investments / Income Producing Investments / Determination of Project Cash Flow / Financial Leverage / Basic Statistics and Probability / Sensitivity AnalysisSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The Andromeda Galaxy ¿ Messier¿s M31 ¿ has an almost romantic appeal. It is the most distant object and the only extragalactic object that is visible to the unaided human eye. Now known to be about 2¿ million light-years away, it appears in the sky to be several times the width of the full Moon under good seeing conditions. The Andromeda Galaxy and the Rise of Modern Astronomy examines the astronomical studies of Andromeda and its importance to our developing knowledge of the universe. The book discusses how M31 was described both by the Ancients, but more importantly, by astronomers from the nineteenth century to the present.While at the start of the twentieth century the universe was thought of as a finite cosmos dominated by the Milky Way, the study of Andromeda galaxy shattered that image, leading ultimately to the conception of an infinite universe of countless galaxies and vast distances. Even today, M31 is a major focal point for new astronomical discoveries, and it also remains one of the most popular (and rewarding) celestial objects for amateur astronomers to observe and study. This book reveals the little-known history of M31 and the scientists who study it.For all who are interested in astronomy, the skies, and perhaps even the origins of the universe, The Andromeda Galaxy and the Rise of Modern Astronomy provides a first-of-its-kind accessible, informative, and highly readable account of how the study and observation of this celestial object has driven the development of astronomy from ancient times to the present.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Over the last 50 years there have been an increasing number of applications of algebraic tools to solve problems in communications, in particular in the fields of error-control codes and cryptography. More recently, broader applications have emerged, requiring quite sophisticated algebra - for example, the Alamouti scheme in MIMO communications is just Hamilton's quaternions in disguise and has spawned the use of PhD-level algebra to produce generalizations. Likewise, in the absence of credible alternatives, the industry has in many cases been forced to adopt elliptic curve cryptography. In addition, algebra has been successfully applied to problems in signal processing such as face recognition, biometrics, control design, and signal design for radar. This book introduces the reader to the algebra they need to appreciate these developments and to various problems solved by these techniques.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 60 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The Handbook of Recording Engineering is a logical outgrowth of the first two editions of Sound Recording. The ten years since the first edition have seen no slackening in the development of recording technology, and they have wit nessed an almost phenomenal growth in the teaching of recording and audio engineering at all academic levels. The earlier editions of Sound Recording have been widely used as texts at all educational levels, and it is the author's intent in the Handbook of Recording Engineering to produce a book which is even more suited to these purposes. At the same time, the book has been organized as a true handbook, which presents of reference material in easily accessible form. a broad array The organization of the book is unique in that it progresses as the signal transmission chain itself does-from the recording venue on through the micro phone, transmission channel, and finally to the listening environment. The first six chapters thus form a logical sequence, and the author recommends that in structors using the Handbook follow them accordingly. Chapter One presents a discussion of acoustical fundamentals, including an introduction to some basic psychoacoustical considerations having to do with performance spaces. Chapter Two covers the basic operating principles of mi crophones, while Chapter Three extends the discussion of microphones to cover the entire range of stereophonic imaging phenomena.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The innovative and unique feature of this book is that it does not contain theoretical concept that cannot be translated into practice.The model which introduces this volume sets the stage for addressing the major phases of the strategic management process: environmental analysis, strategy formulation and development, strategy evaluation and control. Its conceptual and operational structure is described in the first part, together with a practically oriented definition of strategy, and a brief discussion of the logic and benefits of the judgmental modeling approach to decision making.The second part critically addresses the classical approaches to the analysis of the external and internal environmental factors, which have an impact on the ¿functioning¿ of the basic model, i.e. the structural characteristics of the industry context, and the companies¿ technical, organizational, financial, and human resources, including the translation into operational models of otherwise rather theoretical concepts.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 96 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This tutorial presents a hands-on introduction to a new discrete choice modeling approach based on the behavioral notion of regret-minimization. This so-called Random Regret Minimization-approach (RRM) forms a counterpart of the Random Utility Maximization-approach (RUM) to discrete choice modeling, which has for decades dominated the field of choice modeling and adjacent fields such as transportation, marketing and environmental economics. Being as parsimonious as conventional RUM-models and compatible with popular software packages, the RRM-approach provides an alternative and appealing account of choice behavior. Rather than providing highly technical discussions as usually encountered in scholarly journals, this tutorial aims to allow readers to explore the RRM-approach and its potential and limitations hands-on and based on a detailed discussion of examples. This tutorial is written for students, scholars and practitioners who have a basic background in choice modeling in general and RUM-modeling in particular. It has been taken care of that all concepts and results should be clear to readers that do not have an advanced knowledge of econometrics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 64 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The most critical part of the modern switching-mode power supply is the regulated dc/dc converter. Its dynamic behavior directly determines or influences four of the important characteristics of the power supply: ¿ Stability of the feedback loop ¿ Rejection of input-voltage ripple and the closely-related transient re sponse to input-voltage perturbation ¿ Output impedance and the closely-related transient response to load perturbation ¿ Compatibility with the input EMI filter Due to the complexity of the operation of the converter, predicting its dynamic behavior has not been easy. Without accurate prediction, and depending only on building the circuit and tinkering with it until the operation is satisfactory, the engineering cost can easily escalate and schedules can be missed. The situation is not much better when the circuit is built in the computer, using a general-purpose circuit-simulation program such as SPICE. (At the end of this book is a form for obtaining information on a computer program especially well suited for dynamic analysis of switching-mode power converters: DYANA, an acronym for 'DYnamic ANAlysis. ' DYANA is based on the method given in this book. ) The main goal of this book is to help the power-supply designer in the prediction of the dynamic behavior by providing user-friendly analytical tools, concrete results of already-made analyses, tabulated for easy application by the reader, and examples of how to apply the tools provided in the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book is intended for the use of final-year undergraduates and first-year postgraduates. The aim has been to concentrate on the 'Standard Model' and the gauge symmetries because these form the core of the subject. Leptons, quarks and forces are introduced at the beginning of the book, with a minimum of detail; then follow the experimental techniques. After this introduction the gauge theories are dealt with in order of increasing complexity. Attention is then focused on the hadrons. Deep inelastic scattering ofhadrons is dealt with first, then hadron spectroscopy and finally hadron interactions. Current developments beyond the standard model appear in a last chapter. The appendices contain mathematical detail and other material not included in the main text. These appendices cover kinematic, cross-section and decay-rate formulae; Breit-Wigner resonances; some Clebsch-Gordan coefficient tables; a table of particle properties; a set of exercises and detailed answers; and the Dirac equation. One appendix is devoted to calculating the scattering amplitudes for fermion + fermion going to fermion + fermion, which is, if anything, the 'basic' process. The appendices, apart from tabulations, are mainly intended for the postgraduate, though the interested undergraduate may also find them valuable. Up-to-date references are given at the end of the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This is a compact mtroduction to some of the pnncipal tOpICS of mathematical logic . In the belief that beginners should be exposed to the most natural and easiest proofs, I have used free-swinging set-theoretic methods. The significance of a demand for constructive proofs can be evaluated only after a certain amount of experience with mathematical logic has been obtained. If we are to be expelled from 'Cantor's paradise' (as nonconstructive set theory was called by Hilbert), at least we should know what we are missing. The major changes in this new edition are the following. (1) In Chapter 5, Effective Computability, Turing-computabIlity IS now the central notion, and diagrams (flow-charts) are used to construct Turing machines. There are also treatments of Markov algorithms, Herbrand-Godel-computability, register machines, and random access machines. Recursion theory is gone into a little more deeply, including the s-m-n theorem, the recursion theorem, and Rice's Theorem. (2) The proofs of the Incompleteness Theorems are now based upon the Diagonalization Lemma. Lob's Theorem and its connection with Godel's Second Theorem are also studied. (3) In Chapter 2, Quantification Theory, Henkin's proof of the completeness theorem has been postponed until the reader has gained more experience in proof techniques. The exposition of the proof itself has been improved by breaking it down into smaller pieces and using the notion of a scapegoat theory. There is also an entirely new section on semantic trees.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

The coherence of the various sessions is due to their efforts, and special thanks are due to Sydney Meshkov who was responsible for coor dinating many of the efforts of the moderators and for including essentially all of the frontier developments in high energy physics. Because of the number of papers and their integrated length, it has been necessary to divide these proceedings into two volumes. An effort has been made to divide the material in the two volumes into fundamental questions (including the appearance of magnetic charge in particle physics) and recent high energy results and attendant ppenomenology. These volumes were prepared by Mrs. Helga Billings, Mrs. Elva Brady and Ms. Yvonne Leber, and their dedication and skill are gratefully acknowledged. Their efforts v PREFACE during Orbis were supplemented by those of Mrs. Jacquelyn Zagursky, with our appreciation. The photo graphs were taken by Ms. Shirley Busch.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Architectural stress is the inability of a system design to respond to new market demands. It is an important yet often concealed issue in high tech systems. In From scientific instrument to industrial machine, we look at the phenomenon of architectural stress in embedded systems in the context of a transmission electron microscope system built by FEI Company. Traditionally, transmission electron microscopes are manually operated scientific instruments, but they also have enormous potential for use in industrial applications. However, this new market has quite different characteristics. There are strong demands for cost-effective analysis, accurate and precise measurements, and ease-of-use. These demands can be translated into new system qualities, e.g. reliability, predictability and high throughput, as well as new functions, e.g. automation of electron microscopic analyses, automated focusing and positioning functions.From scientific instrument to industrial machine takes a pragmatic approach to the problem of architectural stress. In particular, it describes the outcomes of the Condor project, a joint endeavour by a consortium of industrial and academic partners. In this collaboration an integrated approach was essential to successfully combine various scientific results and show the first steps towards a new direction. System modelling and prototyping were the key techniques to develop better understanding and innovative solutions to the problems associated with architectural stress.From scientific instruments to industrial machine is targeted mainly at industrial practitioners, in particular system architects and engineers working on high tech systems. It can therefore be read without particular knowledge of electron microscope systems or microscopic applications. The book forms a bridge between academic and applied science, and high tech industrial practice. By showing the approaches and solutions developed for the electron microscope, it is hoped that system designers will gain some insights in how to deal with architectural stress in similar challenges in the high tech industry.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This title focuses on the many aspects of the interaction between plants and heavy metals. Not only it describes the effects of heavy metal toxicity on the plant cell and its organs but it also examines the mechanisms that plants adopt to scavenge heavy metals at cellular, physiological, and metabolic level. Plants and Heavy Metals also analyses Hyperaccumulator plants and shows their potential role in phytoremediation technologies in light of the recent research results.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 100 pp. Englisch.
