Buch. Condizione: Neu. Neuware -The idea for this Handbook dates back more than a dozen years, to the time when I was commissioned by The Mason and Dixon Lines to develop a handbook that would be useful both to their own people and to their shippers in understanding and applying the basic principles of the then-emerging management science of physical distribution management. Then as now, there were several excellent textbooks in the field. But they were written primarily for classroom use, for persons who would be entering careers in the field at a later date. And there was virtually nothing for the working manager or manager-to-be. Thus we saw the need for a hands-on, practically-oriented guide to physical distribution management, written mainly in non-academic language and supplement ing rather than duplicating the excellent existing coverage of inventory theory, queueing and,other textbook subjects. Bear in mind that the times were quite different, back then. The Na tional Council of Physical Distribution Management (NCPDM) had been in existence barely two years, and had fewer than 200 members. Indeed, there were probably not 100 persons in the country who had the title 'Distribution Manager' after their names. Today, of course, the NCPDM has over 2,000 members and the distribution manager title is widely used and recognized. In fact, many who hold the title today were recipients of the original Mason and Dixon materials back then, and quite often car ried the time-honored title of 'Traffic Manager.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 860 pp. Englisch.

Buch. Condizione: Neu. Neuware -This work is Volume II of a two-volume monograph on the theory of deterministic parsing of context-free grammars. Volume I, 'Languages and Parsing' (Chapters 1 to 5), was an introduction to the basic concepts of formal language theory and context-free parsing. Volume II (Chapters 6 to 10) contains a thorough treat ment of the theory of the two most important deterministic parsing methods: LR(k) and LL(k) parsing. Volume II is a continuation of Volume I; together these two volumes form an integrated work, with chapters, theorems, lemmas, etc. numbered consecutively. Volume II begins with Chapter 6 in which the classical con structions pertaining to LR(k) parsing are presented. These include the canonical LR(k) parser, and its reduced variants such as the LALR(k) parser and the SLR(k) parser. The grammarclasses for which these parsers are deterministic are called LR(k) grammars, LALR(k) grammars and SLR(k) grammars; properties of these grammars are also investigated in Chapter 6. A great deal of attention is paid to the rigorous development of the theory: detailed mathematical proofs are provided for most of the results presented.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 440 pp. Englisch.

Buch. Condizione: Neu. Neuware - he 1980s began during a great upswing in the Southwest economy, but what lay ahead was a decade of plummeting oil prices, deflated real estatevaluesandunprecedentedbankfailures. Thethemeofthe Federal T Reserve BankofDallas' second annual conferenceon the Southwesteconomy, 'The 1990s: A Different Decade,' reflected our belief that the beginning ofthe new decade would mark a turn toward economic strength in the Southwest. The conference, held Oct. 26-27, 1989, at Loews Anatole Hotel in Dallas, Texas, brought together more than 250 interested individuals and speakers for anexchangeofinformationand ideas. Topics rangedfrom the currentcondition of the Southwest economy to the factors shaping the future. Theinfluences on the Southwest economy are diverse but interrelated. For example, the Southwest faces a complex dilemma in reforming its educational system. As conference speakers illustrated many times, education reform and the quality ofour schools are closely linked to the region's, if not the nation's, ability to compete in future world markets. These proceedings follow the basic organizational pattern of the confer ence. Keynote and luncheon addresses appear in the first section, General Meetings-The 1990s: ADifferent Decade, which includes speeches by Bobby R. Inman, admiral, United States Navy (retired), and private investor; Robert H. Boykin, president and chief executive officer of the Federal Reserve Bank of Dallas; WilliamH. Cunningham; presidentofthe UniversityofTexas, Austin;and John B. McCoy, chairman and chief executive officer of Banc One Corp. Session One, Meeting the Challenges in Education, provides insight from five experts, who survey the current state ofeducation, past attempts at reform andpossiblesolutions for problemsintheeducationalsystemsofthe Southwest.

Buch. Condizione: Neu. Neuware -This book is about the role of expert systems in marketing, particularly in the consumer goods industry. Section I describes the changing nature of consumer marketing and presents the rationale and need for expert systems. The remainder of the book combines a tutorial on expert systems with a series of expert system prototypes. The tutorial material is presented in three places. First, section II is devoted to introducing expert systems in general. Chapter 3 provides a general introduction to the topic, which is continued in chapter 4 where a small expert system (the Promotion Advisor) is used to illustrate the important features of a backward-chaining, rule-based system. The promotion theme is extended in chapter 5 where a larger system is presented. The material in all three of these chapters was designed as an introduction and tutorial on the most common technology for building applied expert systems: the backward-chaining, rule-based inference engine. Tutorial material is also contained in the body of the chapters that describe the prototypes. This material is usually in the form of sample rules and a description of the process for applying the rules. The third location of the expert system material is in chapters that follow discussions of the prototypes. Chapter 7 is a technical chapter on the coupling of expert systems to traditional systems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 242 pp. Englisch.

Buch. Condizione: Neu. Neuware -Deservedly so, Jules Vuillemin is widely respected and greatly admired. It is not simply that he has produced a large body of outstanding work, in many different areas of philosophy. Or that he combines to an unusual degree rigorous standards with a very wide perspective. Or even that in his path-breaking accounts of algebra, of !)escartes, of Kant and of Russell, he showed in new and profound ways how the histories of science and philosophy could be used to illuminate each other. It is also that he has pursued the application of formal techniques and the defense of liberal institutions with a rare singlemindedness and courage. In a time and place where the former were generally ignored and the latter often attacked, he carried on, at some personal cost, embodying a traditional and ideal conception of the philosophical life, bridging national differences. Those who know him also treasure his friendship. Always curious, he delights in new facts and new experiences, and continually heightens the perception of those around him. Almost yearly, at the College de France he introduced brand new courses always with fresh and fruitful inSights. Exceptionally solicitous, he follows the lives of the families around him in great detail. The devotion of his students is legend. His personal energy is also legend. Many of us have followed him bounding up the stairs two at a time or through the gardens of the Luxembourg, his wit and irony apace.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 256 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This dictionary is testimony to the dynamic nature of the transportation and logistics field. The field continues to grow and evolve into an increasing myriad of orientations. This work stems back to the middle 1970s with the first edition by Wallace I. Little (1921 - 1977). The second edition in 1982 contained over five hundred additions and nearly sixty major alterations. This tJ:llrd edition contains over three hundred additional entries as well as major ai~erations to over fifty of them. Transportation continues to change into a market driven industry. The user side reflects market- and management-driven emphases that would have been labeled as pure fiction just a decade ago. Some of these changes are: ¿ Deregulation ¿ Purchasing evolving closer to logistics and having greater roles in with traffic ¿ Logistics having close association with production, scheduling, and related areas ¿ Computers and electronic links becoming major parts of the traffic/ transportation/purchasing landscape ¿ Greater international corporate orientations ¿ Need for logistics flexibility regarding pro-action in the face of energy, interest cost, inflation, international competition, and other major environmental forces ¿ Increased roles of non-economic regulations and policies In addition to the changes in the transport-traffic management interface, the shipper side of the world has extended to be linked with such titles and functions as materials, distribution, warehousing, inventory, customer service, order entry, planning, production scheduling, and in many cases purchasing. This dictionary is a document that will continue to grow.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Buch. Condizione: Neu. Neuware -Louis Phlips The stabilisation of primary commodity prices, and the related issue of the stabilisation of export earnings of developing countries, have traditionally been studied without reference to the futures markets (that exist or could exist) for these commodities. These futures markets have in turn been s~udied in isolation. The same is true for the new developments on financial markets. Over the last few years, in particular sine the 1985 tin crisis and the October 1987 stock exchange crisis, it has become evident that there are inter actions between commodity, futures, and financial markets and that these inter actions are very important. The more so as trade on futures and financial markets has shown a spectacular increase. This volume brings together a number of recent and unpublished papers on these interactions by leading specialists (and their students). A first set of papers examines how the use of futures markets could help stabilising export earnings of developing countries and how this compares to the rather unsuccessful UNCTAD type interventions via buffer stocks, pegged prices and cartels. A second set of papers faces the fact, largely ignored in the literature, that commodity prices are determined in foreign currencies, with the result that developing countries suffer from the volatility of exchange rates of these currencies (even in cases where commodity prices are relatively stable). Financial markets are thus explicitly linked to futures and commodity markets.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Buch. Condizione: Neu. Neuware -It is difficult to do justice to fracture mechanics in a textbook, for the subject encompasses so many disciplines. A general survey of the field would serve no purpose other than give a collection of references. The present book by Professor E. E. Gdoutos is refreshing because it does not fall into the esoteric tradition of outlining equations and results. Basic ideas and underlying principles are clearly explained as to how they are used in application. The presentations are concise and each topic can be understood by advanced undergraduates in material science and continuum mechanics. The book is highly recommended not only as a text in fracture mechanics but also as a reference to those interested in the general aspects of failure analysis. In addition to providing an in-depth review of the analytical methods for evaluating the fundamental quantities used in linear elastic fracture mechanics, various criteria are discussed re:O. ecting their limitations and applications. Par ticular emphases are given to predicting crack initiation, subcritical growth and the onset of rapid fracture from a single criterion. Those models in which it is assumed that the crack extends from tip to tip rely on the specific surface energy concept. The differences in the global and energy states before and after crack extension were associated with the energy required to create a unit area of crack surface. Applications were limited by the requirement of self-similar crack growth.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Buch. Condizione: Neu. Neuware -The tenn 'calixarenes', introduced in 1978 by D. Gutsche to describe the cyclic oligomers produced by condensation of p-substituted phenols with fonnaldehyde, is now universally accepted in the chemical community. The condensation of phenol with fonnaldehyde was studied in the last century by A. von Baeyer. Early in this century, L. Baekeland produced the first entirely synthetic polymers from phenol-fonnaldehyde condensates and the possibility that cyclic condensation products could be obtained from t-butylphenol, and fonnaldehyde was mentioned as early as in the beginning of the 1940's by A. Zinke. Despite their long history, the realisation that calixarenes may have very significant applications and uses in supramolecular chemistry is a relatively recent phenomenon. Calixarene chemistry, in contrast to their discovery, started slowly in the 1970's but rapidly gained momentum throughout the 1980's. Following C. Pedersens discovery of the crown ethers and the seminal developments of J. -M. Lehn and D. Cram with cryptands and spherands - all three honoured with the 1987 Nobel Chemistry Prize - the time was right for a surge of interest in research areas, frequently referred to as host-guest chemistry, receptor or supramolecular chemistry, and including important comparisons with biological processes and the development of new advanced materials. Now, the cyclic, bowl or basket-shaped calixarene molecules were looked on in a different light. Rather than 'having developed from harmful by-products of phenoplasts manufacture' they were now seen as potentially valuable macrocyclic receptor molecules.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Condizione: Neu. Neuware -The middle years of the nineteenth century saw two crucial develop ments in the history of modern logic: George Boole's algebraic treat ment of logic and Augustus De Morgan's formulation of the logic of relations. The former episode has been studied extensively; the latter, hardly at all. This is a pity, for the most central feature of modern logic may well be its ability to handle relational inferences. De Morgan was the first person to work out an extensive logic of relations, and the purpose of this book is to study this attempt in detail. Augustus De Morgan (1806-1871) was a British mathematician and logician who was Professor of Mathematics at the University of London (now, University College) from 1828 to 1866. A prolific but not highly original mathematician, De Morgan devoted much of his energies to the rather different field of logic. In his Formal Logic (1847) and a series of papers 'On the Syllogism' (1846-1862), he attempted with great ingenuity to reformulate and extend the tradi tional syllogism and to systematize modes of reasoning that lie outside its boundaries. Chief among these is the logic of relations. De Mor gan's interest in relations culminated in his important memoir, 'On the Syllogism: IV and on the Logic of Relations,' read in 1860.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Condizione: Neu. Neuware -Large computational resources are of ever increasing importance for the simulation of semiconductor processes, devices and integrated circuits. The Workshop on Computational Electronics was intended to be a forum for the dis cussion of the state-of-the-art of device simulation. Three major research areas were covered: conventional simulations, based on the drift-diffusion and the hydrodynamic models; Monte Carlo methods and other techniques for the solution of the Boltzmann transport equation; and computational approaches to quantum transport which are relevant to novel devices based on quantum interference and resonant tunneling phenomena. Our goal was to bring together researchers from various disciplines that contribute to the advancement of device simulation. These include Computer Sci ence, Electrical Engineering, Applied Physics and Applied Mathematics. The suc cess of this multidisciplinary formula was proven by numerous interactions which took place at the Workshop and during the following three-day Short Course on Computational Electronics. The format of the course, including a number of tutorial lectures, and the large attendance of graduate students, stimulated many discussions and has proven to us once more the importance of cross-fertilization between the different disciplines.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - Endocrinology is a field in which enormous advances have been made in the last decade; the rate of discovery of new hormones, hormone-like molecules, receptors, and mechanisms of action is continually advancing. The development of techniques in immunology and molecular biology has led to the possibility of describing in detail the gene structure of many of the compounds involved in hormonal systems. Remarkable homology has been shown between oncogene products and various components of the endocrine network, leading to the asser tion that deregulation of hormonal function is involved in the generation and/or development of cancer. We now know that the central nervous system is both a target and a production site of many hormonal products, and that hormones, neurotransmitters, growth factors and immunopeptides all act through similar mechanisms. The only second messenger known ten years ago was cAMP; today calcium, derivatives of membrane phospholipids, and protein kinases are also known to be mediators of hormone action. The very concept of hormonal systems has been expanded to include not only endocrine secretions but also para- and autohormones and their mechanisms of action; an understanding of their functions will be central to the immediate future of medicine. The discovery of hormonal molecules and endocrine interactions and the subsequent understanding of hormone related pathophysiology has led to the development of new strategies in medical treatment such as fertility control and the management of diabetes.

Buch. Condizione: Neu. Neuware -In today's electronics business, managing an ESD progranris an integral part of a complete quality program. In fact, any electronics firm without an active ESD program puts itself and its customers at risk. This book illustrates one good example of the detail and dedication to quality that AT&T expects within its own operations and from its suppliers. Writing of the book began at a time when Ted Dangelmayer was burdened with many demands. These demands were from AT&T's own operations, internal suppliers, external suppliers, customers and others looking for a better understanding of the phenomenon of ESD, its impact and, most of all, ways to control and manage it. In a way, this book is a response to these demands by making available a reader friendly document that distills the hard-won experiences of Ted and AT&T. The information and methods in this book have been gained at no small cost and produce results that far exceed eXRenses. There is, however, a caveat: Success will not be obtained unless there is real management commitment. This means management must allocate the necessary resources and provide active support to ensure that training, auditing, reporting, tracking and an aggressive corrective action program all take place successfully. Ted is an internationally recognized authority, and you will benefit greatly by listening to his advice and following his recommendations. 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Analog circuit design has grown in importance because so many circuits cannot be realized with digital techniques. Examples are receiver front-ends, particle detector circuits, etc. Actually, all circuits which require high precision, high speed and low power consumption need analog solutions. High precision also needs low noise. Much has been written already on low noise design and optimization for low noise. Very little is available however if the source is not resistive but capacitive or inductive as is the case with antennas or semiconductor detectors. This book provides design techniques for these types of optimization. This book is thus intended firstly for engineers on senior or graduate level who have already designed their first operational amplifiers and want to go further. It is especially for engineers who do not want just a circuit but the best circuit. Design techniques are given that lead to the best performance within a certain technology. Moreover, this is done for all important technologies such as bipolar, CMOS and BiCMOS. Secondly, this book is intended for engineers who want to understand what they are doing. The design techniques are intended to provide insight. In this way, the design techniques can easily be extended to other circuits as well. Also, the design techniques form a first step towards design automation. Thirdly, this book is intended for analog design engineers who want to become familiar with both bipolar and CMOS technologies and who want to learn more about which transistor to choose in BiCMOS. 228 pp. Englisch.

Buch. Condizione: Neu. Neuware -Helminths include one of the most diverse and geographically widespread groups of parasites which infect humans and animals. About 100 species have been reported from humans, usually producing asymptomatic infection or mild symptoms. However, about 20 species are of public health importance causing severe or even fatal infections. In many parts of Africa parasitic helminths are responsible for enormous economic losses, hampering rural development programmes and reducing the pace of economic growth. Many parasitic helminths are either zoonoses (diseases naturally transmitted between vertebrate animals and man) or have evolved from animal parasites. The modification of the environment through wars, famine and the ever expanding and increasingly mobile human population brings people into close contact with new environments and wildlife species which makes the study and control of zoonoses of special interest and complexity. In Africa, the transmission of helminth parasites is highly influenced by the ever changing social and cultural differences between diverse groups of peoples and their interaction with wild and domestic animals. It is not surprising, therefore, that approaches to the study and control of parasitic zoonoses require intersectoral cooperation between physicians, veterinarians, parasitologists, zoologists, demographers, anthropologists, engineers and economists to provide the breadth of knowledge and expertise required to develop our understanding of these diseases and to devise methods for their control. This book provides a selective compilation of parasitic helminths, many of which are zoonoses which create important economic and public health problems in Africa.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Buch. Condizione: Neu. Neuware -' ['etat pathologique ne differe point radicalement de ['etat physiologique, a ['egard duquel if ne suarait constituer, sous un aspect quelconque, qu'un simple prolongement plus ou moins etendu des limites de variation, soit superieures, soit in/erieures, propres a chaque phenomene de ['organisme normal, sans pouvoir jamais produire de phenomenes vraiment nouveaux, qui n'auraient point, a un certain degre, leurs analogues purement physiologiques. Par une suite necessaire de ce principe, la notion exacte et rationnelle de ['etat physiologique doit donc /ournir, sans doute, l'indespensable point de depart de toute saine theorie pathologique, mais if en resulte, d'une maniere non moins evidente, que, reciproquement, ['exam en scienti/ique des phenomenes pathologiques est eminemment propre a per/ectionner les etudes uniquement relatives a ['etat normal. Un tel mode d'experimentation, quoique indirect. est, en general, mieux adapte qu'aucun autre a la vraie nature des phenomenes biologiques. ' (Comte, 1838; pg 696). The principle that an unde. rstanding of physiology can be based on the analysis of pathological states, and that, vice versa, an understanding of pathology cannot proceed without a clear formulation of the structure on normal physiological states formed the basis for the development of experimental medicine in France in the first half of the 19th century, and for the development of neuropsychology in the second half of the 19th century.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 464 pp. Englisch.

Buch. Condizione: Neu. Neuware -overall title and the commentary of Narboni, but in which the treatise is given a close association rath De Substantia Orbis VII, which immedi ately follows it in the text. This third version is the sole case in which a Hebrew translator can be named: the translation was made by Todros Todrosi in the year 1340. The only conclusion to be drawn from his translation is that Todrosi may definitively be eliminated as the translator of any of the other ver sions. However, we may be able to draw a tentative conclusion as to the formation of the Hebrew collection. The earliest evidence for the existence of the nine treatise collec tion is the commentary of Narboni, completed in 1349. The fact that nine years earlier one treatise could be attached to a work outside the corpus may indicate that the Hebrew collection of nine treatises was formed during those nine years, or mar even indicate that Narboni him self collected the various treatises. 5 Narboni, however, was not the translator of these works In fact, no 1 definitive indication of the translator's identity exists. 6 3. The Nature of the Question-Form Steinschneider offered the following general characterization of Aver roes' Quaestiones: These are mostly brief discussions, more or less answers to questions; they may be partially occasioned by topics i9 his commentaries and may be considered as appendices to them.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.
