This item is printed on demand - it takes 3-4 days longer - Neuware -In spite of all emphasis on objectivity, a scientific discipline needs for its development outstanding research workers with exceptional personal qualities. A scientist with these qualities is honoured here, on the occasion of his 70th birthday, by his pupils, friends and colleagues: Arthur Linder is respected as a researcher, advisor and teacher in the field of Applied Statistics. Professor Dr. Dr. h. c. A. Linder has demonstrated the utility of statistical methods in science and technology; these are recognised today as being essen tial for an objective evaluation of data. His contacts with Sir R. A. Fisher, C. 1. Bliss, G. M. Cox, W. G. Cochran, P. C. Mahalanobis and many other ex perts, have helped him to achieve his almost legendary authority on sampling and on the evaluation of statistical data. Linder has won many friends and adherents to the cause of Biometry, Econometry and Technometry, firstly through his teaching activity at the universities of Berne, Geneva and Lausanne and the Swiss Federal Institute of Technology in Zurich, and as visiting lecturer at the Indian Statistical Institute, the International Statistical Education Centre in Calcutta, the Uni versity of North Carolina and the University of Natal in Durban, secondly through his contributions to the literature as author of the monographs 'Sta tistische Methoden' and 'Planen und Auswerten von Versuchen', as editor of METRIKA and co-editor of other journals, and thirdly through his active collaboration in the founding of The Biometric Society, to the presidency of 262 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Whilst improperly posed problems appear in several branches of applied and pure mathematics, this conference concentrated mainly on the practical treatment of ill posedness. The participants came from 12 countries. The interchange of ideas reflected the spectrum of questions arising in connection with the subject of the conference, where currently progresses in research are made. This volume contains 17 papers presented at the con ference. Focal points in the programme were: Problems of regularisation, parameter identification, free boundary and inverse problems in differential equations and inte gral equations of the first kind. Problems, which appear in science, in technical fields and in medicine are dis cussed as well as general operator equations. In a jOint discussion, several open problems have been worked out which are collected at the end of the volume. The editor's thanks go to all contributors and parti cipants who made the conference a success; to the manage ment of the institute with its unique atmosphere; to the Birkhauser Verlag for the possibility to publish the vo lume in the well-known ISNM series; to Dr. P. Jochum (Mlin chen) for assistance in organization and to Mrs. Chr. Rogg (Augsburg) for her excellent typing of several manuscripts. 264 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Methods in protein sequence analysis constitute important fields in rapid progress. We have experienced a continuous increase in analytical sensitivity coupled with decreases in time necessary for purification and analysis. Several generations of sequencers, liquid/solid/gas-phase, have passed by and returned in other shapes during just over two decades. Similarly, the introduction of HPLC permitted an enormous leap forward in this as in other fields of biochemistry, and we now start to see new major advances in purification/analysis through capillary electrophoresis. Furthermore, progress in the field of mass spectrometry has matched that in chemical analysis and we witness continuous development, now emphasizing ion spray and other mass spectrometric approaches. In short, protein analysis has progressed in line with other developments in modern science and constitutes an indispensable, integral part of present-day molecular biology. Even the available molecular tools, in the form of proteases with different specificities, have increased in number, although we still have far to go to reach an array of 'restriction proteases' like the sets of nucleases available to the molecular geneticist. Of course, conferences have been devoted to protein sequence analysis, in particular the MPSA (Methods in Protein Sequence Analysis) series, of which the 8th conference took place in Kiruna, Sweden, July 1-6 1990. Again, we witnessed much progress, saw new instruments, and experienced further interpretational insights into protein mechanisms and functions. 398 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Eleventh International Transport Theory Conference and Symposium in honor of the sixty-fifth birthday of Kenneth Case and the sixtieth birthday of Paul Zweifel was held in Blacksburg, Virginia, during May 22-26, 1989, on the campus of Virginia Polytechnic Institute and State University (Virginia Tech). This volume consists of a selection of the invited papers delivered at the Conference, and represents a cross section of the research currently being carried out in the field of transport theory. The volume is divided into two sections. The Symposium lectures are intended each to summarize an important aspect of transport theory, as well as to present timely new results of the author's research interest. The Conference lectures are contributions of each author on his current research. As has been the custom in this series of conferences, each lecturer was invited to participate by the organizing committee of the Conference: W. Greenberg, Virginia Tech, chairman; V. Boffi, Universita di Firenze; N. Corngold, California Institute of Technology; B. Ganapol, University of Arizona; N. McCormick, University of Washington; P. Nelson, Texas Tech; G. Pomraning, University of California, Los Angeles. The Eleventh International Transport Theory Conference was funded by generous con tributions from Science Applications International Corporation, R. Beyster, president, and from Virginia Polytechnic Institute and State University. Conference participants, and, we believe, researchers in this and related areas, are indebted to these organizations. We would like to thank Lamberto Rondoni, in the graduate program at Virginia Tech, for proofreading manuscripts of all the Italian contributors. 330 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last two decades the theory of abstract Volterra equations has under gone rapid development. To a large extent this was due to the applications of this theory to problems in mathematical physics, such as viscoelasticity, heat conduc tion in materials with memory, electrodynamics with memory, and to the need of tools to tackle the problems arising in these fields. Many interesting phenomena not found with differential equations but observed in specific examples of Volterra type stimulated research and improved our understanding and knowledge. Al though this process is still going on, in particular concerning nonlinear problems, the linear theory has reached a state of maturity. In recent years several good books on Volterra equations have appeared. How ever, none of them accounts for linear problems in infinite dimensions, and there fore this part of the theory has been available only through the - meanwhile enor mous - original literature, so far. The present monograph intends to close this gap. Its aim is a coherent exposition of the state of the art in the linear theory. It brings together and unifies most of the relevant results available at present, and should ease the way through the original literature for anyone intending to work on abstract Volterra equations and its applications. And it exhibits many prob lems in the linear theory which have not been solved or even not been considered, so far. 366 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ten years ago interest in leukocyte chemotaxis was restricted to a relatively small group of scientists whose interests were quite circumscribed. In the past decade both the number of workers and their publications has grown at some thing approaching an exponential rate and, more importantly, the field has gradually expanded to encompass a large number of diverse areas (mediators, receptors, cell effector mechanisms, regulatory factors, etc.). It is now apparent that leukocytes are particularly useful for studies of the locomotory behavior of all cell types and of mechanisms controlling cell movement and orientation. Chemotactic factors, once discovered as substan ces able to induce directional migration in leukocytes, are now recognized as potent stimulators of a variety of cell functions. Based on our knowledge in the field of basic research in leuko cyte chemotaxis, clinical observations in combination with ex perimental studies in vivo have provided new insights into the role of leukocyte-mediator interactions. The recognition that a specific interaction between chemotactic factor and leukocyte can lead to a multitude of cellular responses and products has opened up a broad area of study. The diversity of contributions to this volume based on a conference which was held in May 1982 in Gersau, Switzerland, reflects this development and demonstra tes that leukocyte chemotaxis continues to be an area of fasci nating and highly active research. 440 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of the Lebesgue integral is still considered as a difficult theory, no matter whether it is based the concept of measure or introduced by other methods. The primary aim of this book is to give an approach which would be as intelligible and lucid as possible. Our definition, produced in Chapter I, requires for its background only a little of the theory of absolutely convergent series so that it is understandable for students of the first undergraduate course. Nevertheless, it yields the Lebesgue integral in its full generality and, moreover, extends automatically to the Bochner integral (by replacing real coefficients of series by elements of a Banach space). It seems that our approach is simple enough as to eliminate the less useful Riemann integration theory from regular mathematics courses. Intuitively, the difference between various approaches to integration may be brought out by the following story on shoemakers. A piece of leather, like in Figure 1, is given. The task consists in measuring its area. There are three shoemakers and each of them solves the task in his own way. A B Fig. 1 The shoemaker R. divides the leather into a finite number of vertical strips and considers the strips approximately as rectangles. The sum of areas of all rectangles is taken for an approximate area of the leather (Figure 2). If he is not satisfied with the obtained exactitude, he repeats the whole procedure, by dividing the leather into thinner strips. 233 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Volume 39 of 'Progress in Drug Research' contains eight reviews and the various indexes which facilitate its use and establish the con nection with the previous volumes. The articles in this volume deal with polyamines as tumor markers; the histamine (H3)-receptor and its role as a general regulatory system; with cytokines as immunosti mulants and immunosuppressants as well as potential anticancer agents; with fibrinolysis and clinical use of thrombolytic agents; and with catechol O-methyltransferase and its inhibitors, which are of potential interest in the treatment of Parkinson's disease. An exten sive review on antihistamines (HI) provides an excellent survey of this area in drug research. In the 32 years that 'Progress in Drug Research' has existed, the Editor has enjoyed the valuable help and advice of many colleagues. Readers, the authors of the reviews, and, last but not least, the review ers have all contributed greatly to the success of the series. Although the comments received so far have generally been favorable, it is nevertheless necessary to analyze and to reassess the current position and the future direction of such a review series. 399 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These proceedings contain a selection of papers presented at the Third European Conference on Multigrid Methods which was held in Bonn on October 1-4, 1990. Following conferences in 1981 and 1985, a platform for the presentation of new Multigrid results was provided for a third time. Multigrid methods no longer have problems being accepted by numerical analysts and users of numerical methods; on the contrary, they have been further developed in such a successful way that they have penetrated a variety of new fields of application. The high number of 154 participants from 18 countries and 76 presented papers show the need to continue the series of the European Multigrid Conferences. The papers of this volume give a survey on the current Multigrid situation; in particular, they correspond to those fields where new developments can be observed. For example, se veral papers study the appropriate treatment of time dependent problems. Improvements can also be noticed in the Multigrid approach for semiconductor equations. The field of parallel Multigrid variants, having been started at the second European Multigrid Conference, is now at the centre of interest. 394 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Tamari lattices originated from weakenings or reinterpretations of the familar associativity law. This has been the subject of Dov Tamari's thesis at the Sorbonne in Paris in 1951 and the central theme of his subsequent mathematical work. Tamari lattices can be realized in terms of polytopes called associahedra, which in fact also appeared first in Tamari's thesis. By now these beautiful structures have made their appearance in many different areas of pure and applied mathematics, such as algebra, combinatorics, computer science, category theory, geometry, topology, and also in physics. Their interdisciplinary nature provides much fascination and value. On the occasion of Dov Tamari's centennial birthday, this book provides an introduction to topical research related to Tamari's work and ideas. Most of the articles collected in it are written in a way accessible to a wide audience of students and researchers in mathematics and mathematical physics and are accompanied by high quality illustrations. 456 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The development of many important directions of mathematics and physics owes a major debt to the concepts and methods which evolved during the investigation of such simple objects as the Sturm-Liouville equation 2 2 y' + q(x)y = zy and the allied Sturm-Liouville operator L = - d /dx + q(x) (lately Land q(x) are often termed the one-dimensional Schrödinger operator and the potential). These provided a constant source of new ideas and problems in the spectral theory of operators and kindred areas of analysis. This sourse goes back to the first studies of D. Bernoulli and L. Euler on the solution of the equation describing the vibrations of astring, and still remains productive after more than two hundred years. This is confirmed by the recent discovery, made by C. Gardner, J. Green, M. Kruskal, and R. Miura [6J, of an unexpected connection between the spectral theory of Sturm-Liouville operators and certain nonlinear partial differential evolution equations. The methods used (and often invented) during the study of the Sturm-Liouville equation have been constantly enriched. In the 40's a new investigation tool joined the arsenal - that of transformation operators. 367 pp. Deutsch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -FirstEdition DUE TO THE necessity to save weight and materialin the design ofmodern structures and machines, stability problems have become increasingly im portant. The classicalengineering approach to this type of problem has been characterized by the tacit assumption that structures are nongyroscopic conservative systems,that is, bythegeneraladoptionofthemethodsdeveloped for this particular case. During the last decades numerous stability problems of a more complicated nature have become important, and it has therefore become necessary to correlate the various types of problems with the ap proaches to be used in their solution. The principal object ofthis little bookisthis correlation between the systems to be investigated and the methods to be used for this purpose, In other words, our main concern is the choice of a correct approach. It is evident that this idea renders it necessary to distinguish between the various types of problems or systems. At the same time the similarities and the connections between apparently quite different problems will become obvious, and it will be evident that there islittle differencebetween, say, the buckling of a column, thecritical speed of a turbine shaft, and the stability of an airplane, a control mechanism, or an electric circuit. 150 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The primary objective of this monograph is to develop an elementary and self contained approach to the mathematical theory of a viscous incompressible fluid in a domain 0 of the Euclidean space ]Rn, described by the equations of Navier Stokes. The book is mainly directed to students familiar with basic functional analytic tools in Hilbert and Banach spaces. However, for readers' convenience, in the first two chapters we collect without proof some fundamental properties of Sobolev spaces, distributions, operators, etc. Another important objective is to formulate the theory for a completely general domain O. In particular, the theory applies to arbitrary unbounded, non-smooth domains. For this reason, in the nonlinear case, we have to restrict ourselves to space dimensions n = 2,3 that are also most significant from the physical point of view. For mathematical generality, we will develop the lin earized theory for all n 2 2. Although the functional-analytic approach developed here is, in principle, known to specialists, its systematic treatment is not available, and even the diverse aspects available are spread out in the literature. However, the literature is very wide, and I did not even try to include a full list of related papers, also because this could be confusing for the student. In this regard, I would like to apologize for not quoting all the works that, directly or indirectly, have inspired this monograph. 367 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This topical volume covers a wide range of multidisciplinary topics, the common theme of which is processing of remotely-acquired spatial data using geo information methods. Satellite or airborne technologies and geo information itself provide powerful tools for solving numerous scientific problems in the geosciences, as they utilize geophysical principles and offer geophysicists new data and methods. Accordingly, this topical volume focuses on six key topics, presenting research applications of satellite or airborne technologies in geodynamics, geomorphology, meteorology and climatology, hydrology and limnology, oceanography and cartography. These applications make use of numerous remote sensing or observational platforms, including: Light Detection and Ranging (LiDAR), Airborne Laser Scanning (ALS), Rapid Eye, Shuttle Radar Topography Mission (SRTM), Landsat-7, Enhanced Thematic Mapper Plus (ETM+), Moderate-resolution Imaging Spectroradiometer (MODIS), Global Navigation SatelliteSystem (GNSS), Satellite Laser Ranging (SLR), Lunar Laser Ranging (LLR), Doppler Orbitography and Radio positioning Integrated by Satellite (DORIS), as well as several altimetric and gravimetric satellite missions. The remotely-sensed data are processed using various geo information techniques, e.g. spatial interpolation and modeling, object-based image analysis, statistical and geo statistical inference and visualization.The volume addresses the interests of scientists and practitioners whose work is related to processing remote sensing data using geoinformation methods. Postgraduate students of geography, geodesy, cartography and geophysics ¿ as well as students of the broader geosciences ¿ will also find the book to be a valuable resource, as it brings together numerous satellite and airborne technologies with geospatial processing methods, presents case studies and examines most applications in the context of basic geophysical principles.Springer Nature c/o IBS, Benzstrasse 21, 48619 Heek 316 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although the study of dynamical systems is mainly concerned with single trans formations and one-parameter flows (i. e. with actions of Z, N, JR, or JR+), er godic theory inherits from statistical mechanics not only its name, but also an obligation to analyze spatially extended systems with multi-dimensional sym metry groups. However, the wealth of concrete and natural examples, which has contributed so much to the appeal and development of classical dynamics, is noticeably absent in this more general theory. A remarkable exception is provided by a class of geometric actions of (discrete subgroups of) semi-simple Lie groups, which have led to the discovery of one of the most striking new phenomena in multi-dimensional ergodic theory: under suitable circumstances orbit equivalence of such actions implies not only measurable conjugacy, but the conjugating map itself has to be extremely well behaved. Some of these rigidity properties are inherited by certain abelian subgroups of these groups, but the very special nature of the actions involved does not allow any general conjectures about actions of multi-dimensional abelian groups. Beyond commuting group rotations, commuting toral automorphisms and certain other algebraic examples (cf. [39]) it is quite difficult to find non-trivial smooth Zd-actions on finite-dimensional manifolds. In addition to scarcity, these examples give rise to actions with zero entropy, since smooth Zd-actions with positive entropy cannot exist on finite-dimensional, connected manifolds.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the most interesting aspects of thermogenesis research is that it quite naturally attracts workers from an extremely wide spectrum of interests, ranging from the mechanism of cellular respiratory control at the molecular level and neuro-hormonal control of energy dissipation both at the cellular level and that of the whole organisms to the mechanism of temperature control during the hibernating cycle and that of cold acclimatation. Thus, the Satellite Symposium on 'The Effectors of Thermogenesis' brought together not only physiologists, but also biochemists, pharmacologists, zoologists and clinicians, and provided a forum for the airing of new ideas as well as for the confrontation of different points of view. These are now reproduced in this book in exactly the same form and order in which they were presented at the Symposium, in the hope of providing a bird's-eye view of the various facets of thermogenesis research. A 'mini-review', summarizing the current knowledge in each domain, therefore precedes the corresponding papers. The editors are deeply indebted to the contributors of these introductory lectures for so competently selecting from the mass of available information in each field, only the most essential elements. This book is dedicated to Dr. Robert Emrie Smith, a pioneer and path-finder in this field, who organized the first meeting on thermogenesis as a satellite of the XXI International Congress of Physiological Sciences and took an active part in the four subsequent meetings.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dieses Buch ist aus Vorlesungen entstanden, die ich seit drei Jahrzehnten an der Eidgenössischen Technischen Hochschule für die Studierenden des Bau ingenieurwesens und der Vermessung, des Maschineningenieurwesens und der Elektrotechnik gehalten habe. Es stellt eine Neufassung der Bände I und II der Mechanik dar, welche seit 1946 im gleichen Verlag (ursprünglich unter meinem und dem Namen meines verehrten Lehrers und Vorgängers, Prof. Dr. ERNST MEISSNER) erschienen ist. Ich habe den schon in der 3. Auflage der früheren Fassung begonnenen Modemisierungsprozeß hier ein Stück weitergeführt und versucht, das Buch theoretisch zu straffen und gleichzeitig in methodischer Hinsicht den heutigen Bedürfnissen anzupassen. So wurde die Kinematik, die ja unmittelbar an die Geometrie anknüpft und daher dem Studierenden nur geringe Anfangsschwie rigkeiten macht, an die Spitze gestellt. Mit dieser Anordnung kann der Begriff der Leistung frühzeitig definiert werden. Das bietet den Vorteil, daß sowohl die Statik wie die Kinetik allein auf ein verallgemeinertes Reaktionsprinzip sowie das Prinzip der virtuellen Leistungen gegründet und damit von zahl reichen überflüssigen Axiomen befreit werden können. Die beiden Prinzipien lassen sich von Anfang an in einer für beliebige Körper gültigen Gestalt formu lieren, und damit kann auf die nur historisch gerechtfertigte, sachlich aber an fechtbare Praxis verzichtet werden, die Mechanik räumlich ausgedehnter Körper aus derjenigen der Massenpunkte zu entwickeln. Aus didaktischen sowie historischen Gründen erscheint es freilich vernünftig, die Axiome der Punkt mechanik zu erwähnen und auch zu verwenden, auch wenn sie sich schließlich als Konsequenzen der beiden genannten Prinzipien herausstellen. 437 pp. Deutsch.…
