Taschenbuch. Condición: Neu. Neuware - This book develops the use of statistical data analysis in finance, and it uses the statistical software environment of S-PLUS as a vehicle for presenting practical implementations from financial engineering. It is divided into three parts. Part I, Exploratory Data Analysis, reviews the mos…t commonly used methods of statistical data exploration. Its originality lies in the introduction of tools for the estimation and simulation of heavy tail distributions and copulas, the computation of measures of risk, and the principal component analysis of yield curves. Part II, Regression, introduces modern regression concepts with anemphasis on robustness and non-parametric techniques. The applications include the term structure of interest rates, theconstruction of commodity forward curves, and nonparametric alternativesto the Black Scholes option pricing paradigm. Part III, Time Series and State Space Models, is concerned with theories of time series and of state space models. Linear ARIMA models are applied to the analysis of weather derivatives, Kalman filtering is applied to public company earnings prediction, andnonlinear GARCH models and nonlinear filtering are applied to stochasticvolatility models. The book is aimed at undergraduate students in financial engineering,master students in finance and MBA's, and to practitioners with financial data analysis concerns.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an attempt to share some of the fascinating and exciting ideas of modern theoretical physics with a non-mathematical audience. I also hope to give some appreciation of the exceptionally creative people who have generate…d these ideas. I had no intention of writing a comprehen sive history of these ideas, however; I apologize to those physicists whose important contributions I may have omitted. Several people have contributed directly to the writing of this book, and I would like to take this chance to thank them. Clive Horwood of Praxis Publishing and Paul Farrell of Copernicus Books have both been supportive of the project. Anna Painter has been an exceptionally thorough editor and has provided invaluable advice. Dr John Mason and Lyman Lyons both offered constructive criticism of an early draft. The errors that remai- and errors and misinterpretations are inevitable in any attempt to explain the subtle ideas of theoretical physics without the aid of mathematics - are my sole responsibility. I would like to thank Ron, Ronnie, Peter, Jackie, Emily, and Abigail for their support. And, most importantly, I would like to thank Heike and Jessica for their patience.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Distributed service networks encompass various facilities with which we have daily contact. In the public sector they include, for instance, ambulance, fire, and police services; in the business sector they include maintenance and r…epair services, road services, courier services, and the like. Policy making problems in distributed service networks can be clearly classified into a number of hierarchical levels. The levels are distinguished by the time horizon of the problem, by the amount of cost involved in the implementation of a solution, and by the political implications of the solution. This top-down classification is typical of what is known as the 'systems approach,' advocating that the direction of the analysis of complex systems should be from the whole to the details. The top-down classification consists of the following categories of policies: 1. Zoning: How should a network be partitioned into subzones 2. Station location: Where should service stations or service units be located 3. Resource allocation: What amount of resources should be allocated to the stations vii viii Preface 4. Dispatching, routing, and repositioning: What is the optimal dis patching policy, what are the optimal routes for nonbusy units, and under what circumstances is it worthwhile to reposition a certain idle unit A top-down approach implies that each of the problems is solved separately; however, the solution of a higher-level problem sets constraints on problems at lower levels. 312 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with the methods and practical uses of regression and factor analysis. An exposition is given of ordinary, generalized, two- and three-stage estimates for regression analysis, the method of principal components being… applied for factor analysis. When establishing an econometric model, the two ways of analysis complement each other. The model was realized as part of the 'Interplay' research project concerning the economies of the European Common Market countries at the Econometrics Department of the Tilburg School of Economics. The Interplay project aims at: a. elaborating more or less uniformly defined and estimated models; b. clarifying the economic structure and the economic policy possible with the linked models of the European Community countries. Besides the model for the Netherlands published here, the models for Belgium, Italy, West Germany and the United Kingdom are ready for linking and for publishing later on. The econometric model presented in this book and upon which the Interplay model is based comprises eleven structural and twenty-one definitional equations; it is estimated with ordinary, two- and three-stage least squares. The analysis of the model is directed at eliminating multicollinearity, accor ding to D.E. Farrar's and R. Glauber's method. In practice, however, complete elimination of multicollinearity leads to an exclusion of certain relations which is not entirely satisfactory. Economic relations can be dealt with more fully by analyzing the variables involved in detail by factor analysis. In this study factor analysis is also a suitable method for a comparative analysis of different periods. 252 pp. Englisch.

You think out loud, 'I knew the property had been sold,'… and your eyes roam over the real estate sign with the angled 'sold' sticker proclaiming that the agent has been successful. 'Thought the job would have come out on the bid list by now,' you mutter as you move back onto the road and head for your office. Later in the day you get the agent on the phone: 'Jim, how did XYZ get the ABC job I saw nothing on the builders' exchange about it.' 'John, XYZ has been negotiating with ABC for the past six weeks. They did one fine job of selling the owner. Under stand they just called on him out of the blue asking for a chance. They put the whole package together, plans and all.' 'Didn't he get another price, Jim ' 'Sure did; two, as a matter of fact. He asked me to get two other contractors capable of doing design-build projects. He liked XYZ better. I don't know the prices, but I really feel those ix x Preface boys impressed him by going to him.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As its name suggests, the 1988 workshop on 'Interacting Electrons in Reduced Dimen the wide variety of physical effects that are associated with (possibly sions' focused on strongly) correlated electrons interacting in quasi-one- an…d quasi-two-dimensional mate rials. Among the phenomena discussed were superconductivity, magnetic ordering, the metal-insulator transition, localization, the fractional Quantum Hall effect (QHE), Peierls and spin-Peierls transitions, conductance fluctuations and sliding charge-density (CDW) and spin-density (SDW) waves. That these effects appear most pronounced in systems of reduced dimensionality was amply demonstrated at the meeting. Indeed, when concrete illustrations were presented, they typically involved chain-like materials such as conjugated polymers, inorganic CDW systems and organie conductors, or layered materials such as high-temperature copper-oxide superconductors, certain of the organic superconductors, and the QHE samples, or devices where the electrons are confined to a restricted region of sample, e. g. , the depletion layer of a MOSFET. To enable this broad subject to be covered in thirty-five lectures (and ab out half as many posters), the workshop was deliberately focused on theoretical models for these phenomena and on methods for describing as faithfully as possible the 'true' behav ior of these models. This latter emphasis was especially important, since the inherently many-body nature of problems involving interacting electrons renders conventional effec tive single-particle/mean-field methods (e. g. , Hartree-Fock or the local-density approxi mation in density-functional theory) highly suspect. Again, this is particularly true in reduced dimensions, where strong quantum fluctuations can invalidatemean-field results. 420 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Presented with a choice of evils, most would prefer to be blinded rather than to be unable to move, immobilized in the late stages of Parkinson's disease. Yet in everyday life, as in Neuroscience, vision holds the centre of the stag…e. The conscious psyche watches a private TV show all day long, while the motor system is left to get on with it 'out of sight and out of mind. ' Motor skills are worshipped at all levels of society, whether in golf, tennis, soccer, athletics or in musical performance; meanwhile the subconscious machinery is ignored. But scientifically there is steady advance on a wide front, as we are reminded here, from the reversal of the reflexes of the stick insects to the site of motor learning in the human cerebral cortex. As in the rest of Physiology, evolution has preserved that which has already worked well; thus general principles can often be best discerned in lower animals. No one scientist can be personally involved at all levels of analysis, but especially for the motor system a narrow view is doomed from the outset. Interaction is all; the spinal cord has surrendered its autonomy to the brain, but the brain can only control the limbs by talking to the spinal cord in a language that it can understand, determined by its pre-existing circuitry; and both receive a continuous stream of feedback from the periphery. 328 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an attempt to compile the most comprehensive listing of chemical electrode potentials to date. In compiling this encyclopedia, many papers, articles, and publi cations-often with contradictory data-were consulted. Of al…l the par published material available, the authors found the following of ticular interest: G. Milazzo and S. Caroli, Tables of Standard Electrode Poten tials, John Wiley and Sons, Inc. (1978). A. J. deBethune and N. A. Swendeman Loud, Standard Aque ous Electrode Potentials and Temperature Coefficients at 25°C, Clifford A. Hempel (1964). W. Mansfield Clark, Oxidation-Reduction Potentials of - ganic Systems, The Williams and Wilkins Co. (1960). However, it was our intent also to include unpublished complex forma tion EMF data. Furthermore, when we consulted published EMF data, we found that the compilations often paid no attention to disparate conditions and varying pressures and electrolyte concentrations. To achieve a useful compilation, we resorted to Nernst equation thermodynamic calculations to reconcile disparate data. We also uti lized the following relationships to calculate EMF values for inclusion in our tables from association constants: In K = nFE log K = -nE(16. 9) RT As a practical example, consider the reaction 3 Ca + Nta- - 2e = Ca(Ntar We may write 2 Ca - 2e = Ca+ EO = -2. 87 2 3 Ca+ + Nta- = Ca(Ntar E, = 3 Ca - 2e + Nta- = Ca(Ntar E2 = xl xII INTRODUCTION Given log K Ca(Ntaf = 6. 41, 6. 41 = -(2)(16. 308 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now well established that laser flow-measuring systems have important advantages over more conventional techniques both for industrial and laboratory applications. These fundamental advantages are indicated by the enormous res…earch effort which has gone into their development over the last decade and by the number of commercial systems which have become available. Although the field is still developing, the most important theoretical results required for relating the system outputs to the fluid flow parameters have now been formulated and a book on the subject therefore seems timely. In the text we have tried to collect together the most important results both from our own papers and from publications by other authors and to present these in a concise and easily readable form. Emphasis has been placed on the fundamental theory and limitations associated with the various techniques rather than on detailed description of specific systems. We have also included a number of new results on areas such as photon counting in turbulent and periodic flows, frequency domain and time domain analysis of laser Doppler velocimeter signals, effect of background noise on system performance, and on cross-correlation techniques for diffusing flows. 308 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -How do we recognize that the number . 93371663 . . . is actually 2 IoglQ(e + 7r)/2 Gauss observed that the number 1. 85407467 . . . is (essentially) a rational value of an elliptic integral-an observation that was critical in the de…velopment of nineteenth century analysis. How do we decide that such a number is actually a special value of a familiar function without the tools Gauss had at his disposal, which were, presumably, phenomenal insight and a prodigious memory Part of the answer, we hope, lies in this volume. This book is structured like a reverse telephone book, or more accurately, like a reverse handbook of special function values. It is a list of just over 100,000 eight-digit real numbers in the interval [0,1) that arise as the first eight digits of special values of familiar functions. It is designed for people, like ourselves, who encounter various numbers computationally and want to know if these numbers have some simple form. This is not a particularly well-defined endeavor-every eight-digit number is rational and this is not interesting. However, the chances of an eight digit number agreeing with a small rational, say with numerator and denominator less than twenty-five, is small. Thus the list is comprised primarily of special function evaluations at various algebraic and simple transcendental values. The exact numbers included are described below. Each entry consists of the first eight digits after the decimal point of the number in question. 436 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -February 14, 1968 marked the thirtieth year since the death of Edmund Landau. The papers of this volume are dedicated by friends, students, and admirers to the memory of this outstanding scholar and teacher. To mention but one side…of his original and varied scientific work, the results and effects of which cannot be dis cussed here, Edmund Landau performed one of his greatest services in developing the analytic theory of prime numbers from a subject accessible only with great difficulty even to the initiated few to the general estate of mathematicians. With the exception of the work of Chebyshev, Riemann, and Mertens, before Landau the problems of this theory were attempted only in a number of papers which were filled with gaps and errors. These problems were such that even Gauss abandoned them after several attempts in his youth, and they were described by N. H. Abel in a letter of 1823 and by O. Toeplitz in a lecture in 1930 as the deepest part of mathe matics. Clarification first began with the papers of Hadamard, de la Vallee Poussin, and von Mangoldt. At the end ofthe foreword to his work' Handbuch der Lehre von der Verteilung der Primzahlen' which appeared in 1909, Landau could thus remark with complete justification: ' . . . The difficulty of the previously unsolved problems has frightened nearly everyone away from the theory of prime numbers. 360 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main object of this book is to reorient and revitalize classical geometry in a way that will bring it closer to the mainstream of contemporary mathematics. The postulational basis of the subject will be radically revised in orde…r to construct a broad-scale and conceptually unified treatment. The familiar figures of classical geometry-points, segments, lines, planes, triangles, circles, and so on-stem from problems in the physical world and seem to be conceptually unrelated. However, a natural setting for their study is provided by the concept of convex set, which is compara tively new in the history of geometrical ideas. The familiarfigures can then appear as convex sets, boundaries of convex sets, or finite unions of convex sets. Moreover, two basic types of figure in linear geometry are special cases of convex set: linear space (point, line, and plane) and halfspace (ray, halfplane, and halfspace). Therefore we choose convex set to be the central type of figure in our treatment of geometry. How can the wealth of geometric knowledge be organized around this idea By defini tion, a set is convex if it contains the segment joining each pair of its points; that is, if it is closed under the operation of joining two points to form a segment. But this is precisely the basic operation in Euclid. 560 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Stanley Friedman University of Illinois Urbana, Illinois A perusal of the table of contents of this short symposium on Insect Endocrinology might lead those who are generally unin structed in Fraenkel's activities to wonder as to ou…r choice of papers. Our justification is based upon our effort to concentrate the symposium upon a single area in which he has had an extended involvement: namely, the metamorphic molt in flies. In so doing, we immediately recognized the enormous humoral and physiological ramifications, both direct and indirect, of such an interest. Our selection of these papers is an attempt to present the broad picture with a few quick strokes. The first offering, by J. H. Willis, et al., is a direct outgrowth of Fraenkel's work with Rudall on the chemistry of the puparium. Their investigations on the structure of fly cuticle and its changes at pupariation (Fraenkel and Rudall, 1940, Proc. Roy. Soc. London (~) 129:1; 1947, ibid, 134:111), provided quanti tative data which have,since that time, influenced our ideas con cerning cuticular changes at metamorphosis and are presently at the center of the controversy over the mechanism of cuticular hardening and darkening (see Hillerton and Vincent, 1979, l.

This item is printed on demand - it takes 3-4 days longer - Neuware -A psychoanalyst, through training and experience, directs the en tire focus of his attention to registering and internalizing the in put of a patient's communications, listening intently for their implied meanings. It is only by uma…veling the mysteries of an un conscious realm of mental activity that it becomes possible to fully comprehend the way in which mental productions are finally ob servable. The psychoanalyst's total personality is the listening in strument, and the messages emanating from this hidden sector most clearly heard, deciphered, and understood are those most resonant with the contents of the psychoanalyst's unconscious. It is probable that a variety of psychoanalysts adopting a listening posture with a given patient would hear and understand a mul tiplicity of different meanings. Over the years, sensitive, well trained psychoanalytic investigators have formulated concepts con cerning mental functioning from disparate and often opposing points of view. These contradictory ideas are offered from a ba sic theoretical foundation placing unconscious mental events as the most important force shaping human experience. Divergent opin ions may at times appear irreconcilable and then serve as the grounds for developing a separate psychoanalytic school of thought. It is not surprising that an exploration of unseen powerful and regressive forces, by a group of scientists with unique in dividual experiences, would yield insights sensitively attuned to a wide variety of important factors determining human develop ment and behavior. 372 pp. Englisch.

'The editors of this work have themselves contributed significantly to…basic knowledge of the mammalian fertilization process. The observations of Don Wolf on sperm penetration, the block to polyspermy and, most recently, sperm hyperactivation in the monkey and human, Gregory Kopf's elucidation of the mechanisms of sperm activation during penetration and the reciprocal dialogue between sperm and egg, and Barry Bavister's definition of culture conditions and requirements necessary for in vitro oocyte maturation, fertilization and development in model mammalian systems including nonhuman primates have contributed greatly to our understanding of the mammalian fertilization process. Wolf, Kopf and Gerrity have enjoyed substantial interaction with clinicians in Departments of Obstetrics and Gynecology and have been directly involved with successful IVF programs. Both Wolf and Kopf have served as research scientists in the Division of Reproductive Biology at the University of Pennsylvania, which, for more than 22 years, has fostered co-mingling of clinically oriented and basic science faculty. It is through such interaction, which clearly exists at many institutions including the University of Wisconsin, that the process of technology transfer is best served. Without an exquisitely coordinated laboratory, there can be no consistent success in human in vitro fertilization. Quality control is pivotal, but close collaboration between the laboratory and the clinic is also essential as information is shared and correlated. 436 pp. Englisch.

This subject is clearly of interest in its own right as a branch of quantum mechanical scattering theory. However, italso serves as an introduction to many of the basic theoretical concepts which are used in inelastic electron scattering and ionization. Consequently this mono graph can be viewed as an introduction to texts where these subjects are treated. 152 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In 1970, under the sponsorship of Oak Ridge Associated Univer sities (ORAU), a group of clinical investigators formed the Cooper ative Group to Study Localization of Radiopharmaceuticals. The first radiopharmaceutical selected for s…tudy was 67-Gallium (67-Ga) administered as the citrate. The object of the study was to de termine the usefulness of 67-Ga in the diagnosis and treatment of patients with various malignancies. Funding for the project was granted by the U. S. Atomic Energy Commission and the National Cancer Institute, National Institutes of Health (NIH). The Nuclear Medicine Department of the Clinical Center, NIH, agreed to assist ORAU with aspects of this study, particularly with 67-Ga scin tigraphy of patients with lymphoma and Hodgkin's disease. Pre liminary reports from the ORAU study are in press. Since April 1971, 67-Ga scintigraphy has gained increasing use in the study of cancer patients at the Clinical Center, NIH, where well over 1000 such patients have been examined by this method. This monograph was written to present selected examples from this group of a variety of malignancies seen in this 28-month period. No attempt has been made to correlate this overall experience statistically. Rather, this presentation is to help familiarize the practitioner of Nuclear Medicine with the wide range of usefulness for 67-Ga scintigraphy while making him aware of the variation in scan appearance and watchful of the many pitfalls of 67-Ga scan interpretation. Permission to use these patient studies and x-rays was generously granted by Dr. Paul P. 244 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This project had its beginnings in the Fall of 1980. At that time Robert Wagner suggested that I investigate compiler optimi zation of data organization, suitable for use in a parallel or vector machine environment. We developed a s…cheme in which the compiler, having knowledge of the machine's access patterns, does a global analysis of a program's operations, and automatically determines optimum organization for the data. For example, for certain architectures and certain operations, large improvements in performance can be attained by storing a matrix in row major order. However a subsequent operation may require the matrix in column major order. A determination must be made whether or not it is the best solution globally to store the matrix in row order, column order, or even have two copies of it, each organized differently. We have developed two algorithms for making this determination. The technique shows promise in a vector machine environ ment, particularly if memory interleaving is used. Supercomputers such as the Cray, the CDC Cyber 205, the IBM 3090, as well as superminis such as the Convex are possible environments for implementation. 156 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The World Congress of In Vitro Fertilization and Alternate Assisted Reproduction, held in Jerusalem, Israel, 2-7 April, 1989, was the sixth in the sequence of these Congresses, but was the first to emphasize the major importance and… the place of assisted reproductive technologies in the treatment of infertility. The eternal City of Jerusalem witnessed the gathering of more than 1500 participants from allover the world who shared and exchanged knowledge and up-to-date experience in this ever-evolving field. The high quality scientific contributions to the Congress culminated in the publication of this Proceedings. It embraces all-important aspects in the field of in vitro fertilization and alternate assisted reproduction. Papers on controversies and diversities of methods to stimulate the ovaries, imaging techniques, basic research and state-of-the-art papers on ovarian physiology, the role of GnRH and its analog, clinical aspects of IVF treatment and cryopreservation, up-to-date techniques in assisted reproductive technologies that are quickly developing in conjunction with IVF, were included. When should IVF be preferable to surgery What are the ex pected up-to-date world results and what are the psychological, moral, ethical and religious implications These are all the concerns of the treating team and are addressed here. Male factor infertility remains a frustrating problem, but advances in the understanding of sperm-egg interaction, sperm evaluation and preparation are reported. Micromanipulation emerges as a possible alternative to bring some relief to this problem, but it also promises to be central in promoting the field of prenatal genetic analysis. 1100 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the lectures and the concluding discussion of the 'Seminar on Safety, Environmental Impact, and Economic Prospects of Nuclear Fusion', which was held at Erice, August 6-12, 1989. In selecting the contributions to…this 9th meeting held by the International School of Fusion Reactor Technology at the E. Majorana Center for Scientific Cul ture in Erice, we tried to provide a comprehensive coverage of the many interre lated and interdisciplinary aspects of what ultimately turns out to be the global acceptance criteria of our society with respect to controlled nuclear fusion. Consequently, this edited collection of the papers presented should provide an overview of these issues. We thus hope that this book, with its extensive subject index, will also be of interest and help to nonfusion specialists and, in general, to those who from curiosity or by assignment are required to be informed on these as pects of fusion energy. 364 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the papers presented at a conference on 'The rehabilitation of severely damaged land and freshwater eco systems in temperate zones', held at Reykjavik, Iceland, from 4th to 11th July, 1976. The meeting was held…under the auspices of the Ecosciences Panel of the N.A.T.O. Science Committee, and the organising expenses and greater part of the expenses of the speakers and chairmen were provided by N.A.T.O. The scientific programme was planned by M. W. Holdgate and M. J. Woodman, in consultation with numerous colleagues, and especially with the Administrative Director of the Conference in Iceland, Dr. Sturla Fridriksson. Iceland proved a particularly suitable location for such a Conference. Geologically, it is one of the youngest countries 1n the world, owing its origin to the up-welling of volcanic rock along the spreading zone of the mid-Atlantic ridge within the past 20 million years. Its structure, northern oceanic situation, recent glaciation and continuing volcanic activity make it distinct as a habitat and have given it a flora and fauna of especial interest. It is also a land of great natural beauty with its ice caps, waterfalls, volcanic landforms, geothermal features and dramatic coasts. In addition, its ecosystems have proved except ionally vulnerable to man's impact and it presents the kind of problem with which the Conference was concerned in an acute form. 512 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The practice of medicine changes continually, as science guides the physician to the accomplishment of his objective, the cure of the patient. Study of the history of medicine shows that often a remedy of a disease was discovered be…fore the cause of the disease was known. Often the remedy was unnecessarily complicated, but when the cause of the trouble was discovered, the cure became simple and safe. It is with the better under standing of the true nature of thyroid disease that this book is concerned. Those who read it will be able to make their treatments of patients with diseases of the thyroid more simple and more safe. Dr. MASAYOSHI AKISADA and Dr. YOSHIHIDE FUJIMOTO have given to thyroidologists a new way of recognizing cancers of the thyroid. Taking advantage of the fact that many cancers of the thyroid contain minute areas of calcification known as psammoma bodies, they have developed a technique of roentgenographic examination of the thyroid that is sensitive enough to show these tiny opacities and to warn the internist and the surgeon that cancer is probably present. There is no question that this sensitive diagnostic test will prove to be of value comparable to that of mammography. 144 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For a number of years it has been a General Motors Research Laboratories custom to hold a symposium on a subject which is new and emerging, and to invite the best people in the world in that subject to come together to talk to each…other. Initially, I had some difficulty in regarding foundry processes as a new and emerging subject. Copper alloys have been in foundry practice for about six thousand years. Foundrymen working with those alloys have been recognized, as such, for nearly all that time. Iron has a much shorter history, probably only three or four thousand years. So what's new What is new is that a subject which has always been so complex and so difficult that it could only be a craft skill, with bits and pieces of knowledge and bits and pieces of insight, has begun to yield to new abilities to solve very complex problems. We do this now because we can handle great amounts of data by computational means, using new and more complicated theoretical treatments than we could deal with before. In fact, we have a new technology with which we can attack these terribly difficult problems. Thus, foundry processing is becoming a new subject because new things can be done with it. 540 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The International Society on Oxygen Transport to Tissue (IS OTT) was founded in 1973 as a scientific society providing a forum for bioengineers, basic scientists (physiologists, biochemists and physicists) and clinicians (including…anesthesiologists, intensive care specialists, pediatricians, neonatologists, internists, surgeons and other specialists) to facilitate the exchange of scientific information among those interested in any aspect of the transport and/or utilization of oxygen in tissues. From the ranks of its members, many fundamental discoveries and inventions have been made involving the many aspects of oxygen transport and utilization by biological tissues. The ISOTT proceed ings, now in its 14th edition, has become a standard work in the field as witnessed by the inclusion in the Science Citation Index of all volumes published so far. The 19th ISOTT Meeting was held in Cura~ao from August 24th through August 30th, 1991. The Cura~ao Meeting attracted 145 registrants and 45 accompanying persons. The format originated by Dr. Ian Llngmuir in 1985, consisting of posters ac companied by an abbreviated oral summary, was again successfully handled with slight modifications. The meeting was introduced by 6 review lectures covering the whole field of oxygen transport from bioengineering, the problem of diffusion in lung, blood and tissue through pathology of oxygen uptake in the lung, oxygen supply dependency of the critically ill to artificial oxygen carriers. A special session dealt with oxygen sup ply under ambiant pressure changes. 968 pp. Englisch.
