Taschenbuch. Condizione: Neu. Neuware - Bereits heute fallen in Deutschland jährlich ca. 1,5 Mio. Tonnen Elektroschrott an, die zum größten Teil auf Deponien abgelagert werden. Die damit für Mensch und Umwelt verbundenen Gefahren bleiben oft unbeachtet. Insbesondere zum Thema Schadstoffe herrschen zum Teil beachtliche Wissensdefizite. In diesem Buch wird zunächst ein Überblick über die große Anzahl der in der Elektrotechnik verwendeten Stoffe gegeben. Eine umfangreiche tabellarische Übersicht ordnet die Werkstoffe dabei den entsprechenden Bauteilen zu. Die beiliegenden Datenblätter enthalten ausführliche Informationen über die wichtigsten Problemstoffe unter Berücksichtigung von Emissionsquellen, toxikologischen Daten, Auswirkungen auf Mensch und Umwelt sowie Entsorgungs- und Verwertungsmöglichkeiten.…

Taschenbuch. Condizione: Neu. Neuware - Das junge Erwachsenenalter nimmt eine Brückenstellung zwischen den Jahren der Jugend und des Erwachsenseins ein. Die besonders entwicklungspsychologische Bedeutung des jungen Erwachsenenalters liegt in der Notwendigkeit, erstmals im Lebenszyklus zu einem tragfähigen Programm persönlicher Grundorientierungen und Verbindlichkeiten zu finden, die weitreichende Konsequenzen für die nachfolgenden Lebensabschnitte besitzen. Ein Vergleich zwischen seelisch gesunden und psychiatrisch erkrankten jungen Menschen erlaubt nicht nur Hinweise auf bedeutsame Entwicklungsverzögerungen, sondern auch auf leicht unerkannte Ressourcen, die in der therapeutischen und rehabilitativen Arbeit verstärkt beachtet werden können.…

Taschenbuch. Condizione: Neu. Neuware - Es sei 9 eine endlich dimensionale Lie-Algebra uber dem Korper der komple xen Zahlen. In der Darstellungstheorie von gist eine der am einfachsten zu stellenden Fragen die nach einer Beschreibung aller irreduziblen Darstellungen von 9 oder (iiquivalent dazu) aller einfacher Moduln uber der universellen ein hullenden Algebra U (g) von g. Eine einfache Antwort auf diese Frage hat man nur, wenn 9 kommutativ ist. Hier ist auch U(g) kommutativ, also entsprechen die Isomorphieklassen einfa cher U (g)-Moduln eindeutig den maximal en Idealen in U (g). Da hier U (g) zur Algebra der polynomialen Funktionen auf dem Dualraum g von 9 isomorph ist, werden diese maximalen Ideale nach dem schwachen Nullstellensatz durch die Punkte von g klassifiziert. Jede irreduzible Darstellung von gist demnach eindimensional, jede Linearform auf 9 legt soleh eine Darstellung fest. Fur andere Lie-Algebren sind die Verhiiltnisse viel komplizierter. 1st 9 zum Beispiel einfach, so ist bisher nur fUr g=Glz eine Klassifikation der irreduzib len Darstellungen bekannt (vorgelegt von R Block), die jedoch weit davon ent femt ist, iihnlich explizit wie die im kommutativen Fall zu sein. Fur noch gro Bere Lie-Algebren scheint selbst eine solehe Klassifikation nicht erreichbar zu sein. Es scheint daher sinnvoll, zuniichst ein einfacheres Problem zu losen, das im kommutativen Fall mit dem alten zusammenfiillt. Dies ist die Untersuchung der primitiven Ideale von U(g), das heiBt der Annullatoren in U(g) der einfa chen U(g)-Moduln. Man mag hoffen, daraus auch Informationen uber die moglichen einfachen Moduln zu erhalten. …

Taschenbuch. Condizione: Neu. Neuware - Dieser Band ist das Ergebnis der mehrjährigen Tätigkeit eines von der Gesellschaft für Informatik (GI) angeregten Arbeitskreises. Das wirtschaftlich eminent wichtige und sich rapide entwickelnde Gebiet der rechnerunterstützten Systeme in der Fertigung zeigte einen großen Bedarf für ein solches Handbuch. Durch dieses Buch soll einerseits dem Experten ein Leitfaden und Nachschlagewerk in die Hand gegeben und andererseits das Management bei der Entscheidungsvorbereitung auf diesem Gebiet unterstützt werden. Es soll eine Hilfestellung sowohl bei der Beurteilung und Auswahl als auch bei der Entwicklung und Einführung solcher Systeme geben. Unter den vielen von Computer Aided Manufacturing beeinflußten Unternehmensbereichen ist besonders die Entwicklung aufzuführen, in der heute häufig schon mit CAD-Techniken gearbeitet wird. Der Bereich CAD wird eingehend in dem ebenfalls von der GI initiierten CAD-Handbuch behandelt und ist daher in dem vorliegenden CAM-Handbuch ausgespart. Das CAD- und das CAM-Handbuch sind somit als zwei sich ergänzende Werke zu betrachten. Der Leser, der sich intensiv mit CAM befaßt, sollte genügend Grundkenntnisse über CAD besitzen, um die Zusammenhänge zwischen diesen beiden Technologien zu verstehen.…

Taschenbuch. Condizione: Neu. Neuware - Okonomie nDd Mathematik - Der Titel der Festschrift zum 65. Geburtstag von Rudolf Henn charakterisiert im lahr 1987 zumindest partiell eine Realitat. So sind die Disziplinen der mathematischen Wirtschaftstheorie, der Statistik und des Operations Research heute fest integrierte Bestandteile eines wirtschafts wissenschaftlichen Studiums. Eine Reihe von makro- und mikrookonomischen Spezialgebieten hat in den vergangenen lahrzehnten eine starke Mathematisie rung erfahren. Bestimmte Elemente der Analysis, der Differenzen- und Diffe rentialgleichungen, der Funktionalanalysis und der linearen Algebra haben zu bedeutenden Entwicklungen in der neoklassischen und mehrsektoralen Wachs tumstheorie, der Gleichgewichtstheorie, der makro- und mikrookonomischen Produktions- und Preistheorie gefUhrt. Empirische Wirtschaftsforschung ohne Okonometrie ist heute nicht mehr denkbar. 1m betriebswirtschaftlichen Bereich sind insbesondere Fragen der Logistik, der Projekt- und Produktionsplanung mit der Anwendung von Modellen und Methoden der Optimierung und der Netzplantechnik verbunden, entscheidungstheoretische Ansatze haben wesent liche Akzente in der Finanzierungs- und Investitionstheorie gesetzt, der Be reich des Marketing erschlieBt sich zunehmend der Anwendung stochastischer und statistischer Methoden. Auf der anderen Seite hat auch die mathematische Okonomie ihrerseits in einigen mathematischen Forschungsrichtungen Im pulse ausgelost. So befaBt sich die diskrete Mathematik mit Fragen der Gra phentheorie und kombinatorischen Optimierung. In der numerischen Mathe matik geht es u. a. urn Probleme der nichtlinearen und stochastischen Optimie rung sowie der Kontrolltheorie und dynamischen Steuerung. Man kann feststellen, daB sich sowohl in der Mathematik als auch in den Wirtschaftswissenschaften sowie in ihrem Verhaltnis zueinander erhebliche Veranderungen vollzogen haben bzw. noch anstehen.…

Neuware -This volume contains review articles which were written by the invited speak ers of the seventh International Summer Institute in Surface Science (ISISS), held at the University of Wisconsin - Milwaukee in July 1985. The form of ISISS is a set of tutorial review lectures presented over a one-week period by internationally recognized experts on various aspects of surface science. Each speaker is asked, in addition, to write a review article on his lecture topic. No single volume in the series Chemistry and Physics of Solid Surfaces can possibly cover the entire field of modern surface science. However, the series as a whole is intended to provide experts and students alike with a comprehensive set of reviews and literature references, particularly empha sizing the gas-solid interface. The collected articles from previous Summer Institutes have been published under the following titles: Surface Science: Recent Progress and Perspectives, Crit. Rev. Solid State Sci. 4, 125-559 (1974) Chemistry and Physics of Solid Surfaces, Vols. I, II, and III (CRC Press, Boca Raton, FL 1976, 1979 and 1982), Vols. IV and V, Springer Ser. Chern. Phys., Vols. 20 and 35, (Springer, Berlin, Heidelberg 1982 and 1984). The field of catalysis, which has provided the major impetus for the de velopment of modern surface science, lost two of its pioneers during 1984 and 1985: Professors G.-M. Schwab (1899-1984) and p.k. Emmett (1900-1985).Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 692 pp. Englisch.…

Neuware -More than a decade has passed since the appearance of the last edition of the book 'Carbon Monoxide in Organic Synthesis'. During the intervening period, the signi ficance of carbon monoxide chemistry has become even more evident. The oil crisis and the ever-present awareness of the constant depletion of the oil reserves have both contributed to a surge in activity. The fact that coal will once again replace oil in the near future as a feedstock source has been an impetus for new efforts in the field of carbon monoxide chemistry. Moreover, older almost neglected processes such as the Fischer-Tropsch synthesis have become a focal point for new activities. Therefore, the time was ripe to fundamentally revise 'Carbon Monoxide in Organic Synthesis' and to complete its coverage by introducing the chapters 'Homo logation' and 'Carbon Monoxide Hydrogenation'. However, other important sectors of carbon monoxide chemistry such as the con version of synthesis gas to methanol or higher alcohols were excluded. These are treated in the book 'Chemierohstoffe aus Kohle', which devotes considerable attention to these syntheses. I would like to thank Drs. Bahrmann, Comils, Frohning, Mullen and Tummes, who had the task of compiling and critically evaluating the large volume of literature which has appeared during the last decade.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Englisch.…

It is estimated that in China rice constitutes about half of the total food production, covering an area of about 30 % of \08 hectares of cultivated land of the whole country. Owing to the peculiar water regime, paddy soils possess quite different properties physically, chemically and biologically as compared with those of upland soils. Such properties have a conspicuous effect on fertility and management practice of paddy field. For the purpose of summing up the past work and opening up new prospects, a 'Symposium on Paddy Soils' was organized under the auspices of Academia Sinica, held on October 19-24, 1980 in Nanjing, which was followed by a seven-day paddy soil excursion in the lower Changjiang Delta. In addition to 120 Chinese soil scientists, 56 guests coming from America, Asia, Europe and Oceania attended the symposium on invitation. A total of 110 papers were presented either orally or by poster. All these are collected and published in the present proceedings which we hope may be helpful to the scientific exchanges between soil scientists of China and other countries.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 884 pp. Englisch.…

Neuware -This volume contains review articles written by the invited speakers at the eighth International Summer Institute in Surface Science (ISISS 1987), held at the University of Wisconsin-Milwaukee in August of 1987. During the course of ISISS, invited speakers, all internationally recognized experts in the various fields of surface science, present tutorial review lectures. In addition, these experts are asked to write review articles on their lecture topic. Former ISISS speakers serve as advisors concerning the selection of speakers and lecture topics. Em phasis is given to those areas which have not been covered in depth by recent Summer Institutes, as well as to areas which have recently gained in significance and in which important progress has been made. Because of space limitations, no individual volume of Chemistry and Physics of Solid Surfaces can possibly cover the whole area of modem surface science, or even give a complete survey of recent pro gress in the field. However, an attempt is made to present a balanced overview in the series as a whole. With its comprehensive literature references and extensive subject indices, this series has become a valu able resource for experts and students alike. The collected articles, which stress particularly the gas-solid interface, have been published under the following titles: Surface Science: Recent Progress and Perspectives, Crit. Rev. Solid State Sci. 4, 125-559 (1974) Chemistry and Physics of Solid Surfaces, Vols.

Neuware -Synchrotron radiation as a spectroscopic research tool has undergone a most inter esting and astonishing historical development and has now come to the stage of an exciting boom. The machines which produce synchrotron radiation were built and de veloped exclusively for other purposes in the past, namely high-energy physics. At the same time, however, they involuntarily became better and better light sources for the spectral range from the visible to the hard x-ray region. Now we are at the point that the first few storage rings have gone into operation as machines dedicated to synchrotron radiation and several more are in the stage of construction and planning. All this was brought about by the successful research performed during the past fifteen years in which several groups allover the world haVe participated at dif ferent accelerator centers mostly symbiotic with high-energy physics. As it happens with a young and rapidly developing field, the number of reviews and monographs is still minute. The objective of this book is to fill an apparent gap and to provide a sound basis for those who are interested in synchrotron radiation and its applica tions.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 464 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The results, published in this book, present the outcome of a cooperative research between plant ecologists, physiologists and population geneticists. The project received generous financial support from the Foundation for Bio logical Research, which is subsidized by the Netherlands Organization for Scientific Research. During the course of the Project the value of the in tegrative approach on a limited number of Plantago species and populations became evident and it was decided that the results should be published as a book. The start of the preparation of the 'plantago' book was done by Dr. P. J. M. van der Aart and Dr. H. Lambers but due to their appointment as full professor of the University of Utrecht they were both unable to continue. We are greatly indebted to Van der Aart and Lambers for the groundwork they have laid. The book presents a sample of results obtained over a period of more than 10 years. Research on Plantago is still continuing, as evident from a number of publications and doctoral theses. We want to thank the authors for their pa tience and assistance to complete the job. The editorial assistance of Mrs. I. Cameron-Doornbos was extremely valuable, as well as the help of Mr. E. Leeuwinga und Mrs. N. Tolmeijer with the drawings and the help of Mrs. T. E.

Neuware -Tommy Bengtsson The Swedish welfare model of the 1960s and 1970s excited great interest among many other countries. Today it still is an ideal image for some but a warning for many others. The reason why opinion about the Swedish welfare model has changed is primarily Sweden's financial problems, which are associated with a badly financed and excessively large public sector. It is argued that the size of the budget deficit is a great problem in itself, but also, and perhaps more importantly, that the large public sector has negative effects on the entire economy since it lead to inefficient allocation of resources. A first step in order to solve these problems is to examine how they arose. The questions then are to what extent the large public sector which Sweden has today results from social entitlements which have come into existence since the 1960s, from the maturing of welfare systems decided upon earlier, from unfavourable demographic developments, or from economic stagnation, and how these factors are interlinked. What is quite clear is that Sweden has had very low economic growth during the 1970s and 1980s compared with the preceding period. But so have many other industrial countries, without their having in consequence found themselves in diffi culties as great as Sweden's. Therefore economic stagnation alone cannot explain Sweden's situation.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 196 pp. Englisch.…

Neuware -In this book, a model of long-term interrelationshipsbetween income distribution, population growth and economicdevelopment is developed and estimated from data for 54countries. The results indicate that a reduction of incomeinequality leads to lower fertility and mortality, toimprovedbasic needs satisfaction, and to lower labour forceparticipation of young and old males and of females in Asiaand Africa. The effect of income distribution on saving andconsumption is found to be negligible. These outcomessuggest that family planning and health policies in LDCswill show better results when they are supplemented withpolicies aimed at makingthe poor benefit from economicgrowth. As regards development policy, the results indicatethat a reduction of income inequality does not impair theformation of physical capital, but enhances the formation ofhuman capital and lowers the growth rate of the labourforce.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 420 pp. Englisch.…

Neuware -In examining the problem of quantization it is customary to proceed by following the order of historical developments, i. e. , to start with the so-called first quantization and then go on to second, or field, quantization. As is well known, the former consists in setting up commutation relations among the canonical variables (of finite degrees of freedom) which are defined originally in classical mechanics, and the latter consists in doing the same among field variables. In our opinion, however, the above order does not necessarily reflect that of physical importance. In fact, a close look at the theoretical that the latter plays a more fundamental role structure immediately reveals than the former in various respects. First, the former can be derived from the latter, and second, the assumptions that have to be made in the former, e. g. the spin-statistics connection, can be justified in the latter on the basis of its own theory. Furthermore, as the history of the positron theory shows, if we remain within the framework of the first-quantized formalism, it will no longer be possible to have a closed theory in the relativistic region where the problem becomes essentially that of an infinite number of particles.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.…

Neuware -This book contains the proceedings of the first Workshop on Interface Phenomena, organized jointly by the surface science groups at Dalhousie University and the University of Maine. It was our intention to concentrate on just three topics related to the kinetics of interface reactions which, in our opinion, were frequently obscured unnecessarily in the literature and whose fundamental nature warranted an extensive discussion to help clarify the issues, very much in the spirit of the Discussions of the Faraday Society. Each session (day) saw two principal speakers expounding the different views; the session chairmen were asked to summarize the ensuing discussions. To understand the complexity of interface reactions, paradigms must be formulated to provide a framework for the interpretation of experimen tal data and for the construction of theoretical models. Phenomenological approaches have been based on a small number of rate equations for the concentrations or mole numbers of the various species involved in a par ticular system with the relevant rate constants either fitted (in the form of the Arrheniusparametrization) to experimental data or calculated on the basis of microscopic models. The former procedure can at best serve as a guide to the latter, and is, in most cases, confined to ruling out certain reaction pathways rather than to ascertaining a unique answer.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 316 pp. Englisch.…

Neuware -Disturbances of haemostasis and thromboembolic disorders still constitute a great problem in clinical practice. Increasing insight into the mechanism of blood coagula tion has led to more effective therapy and prophylaxis. Particularly, the understand ing of the biochemistry of fibrinolysis has provided possibilities for the pharma cological interference of these processes, which has resulted in effective haemostatic agents and useful antithrombotic ones. The development of antifibrinolytics for interfering with pathological fibrinolytic processes is nearly complete and has led to the development of drugs essential to the therapy of hyperfibrinolytic bleeding. The search for fibrinolytics for dissolving intravascular thrombi has led to highly effective compounds. This development is still under way and promising results are hoped. Spontaneous dissolution of blood clots is a phenomenon which was described a century ago. First investigations of this process assured that there is in the organism a system capable of removing the fibrin which is formed during blood coagulation after it has fulfilled its physiological function. This fibrinolytic system is specifically adapted to the degradation of insoluble fibrin into soluble degradation products. In the past 30 years, thorough investigation of this system has clarified the fibrinolytic process, its physiological role and its meaning as a pathogenetic principle. A good knowledge of these processes is required for an understanding of the effects and side effects of fibrinolytics and antifibrinolytics, which comprise the basis of methods for the detection of fibrinolytic processes in the organism and of the control of therapy with these drugs.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 684 pp. Englisch.…

Neuware -This monograph is devoted to the basic aspects of the physics of highly ex cited (Rydberg) states of atom's. After almost twenty years, this remains a hot topic of modern atomic physics. Such studies are important for many areas of physics and its applications including spectroscopy, astrophysics and radio astronomy, physics of electronic and atomic collisions, kinetics and di agnostics of gases, and low- and high-temperature plasmas. Physical phenom ena in radiative, collisional, and spectral-line broadening processes involving Rydberg atoms and ions are primarily determined by the peculiar properties and exotic features of highly excited states. The growth of interest and research activity in the physics of Rydberg the last two decades was stimulated by an extremely rapid de atoms over velopment of high-resolution laser spectroscopy, methods of selective excita tion and detection of highly excited states, atomic-beam techniques as well as radio astronomy. This has facilitated significant progress in the differ ent directions of the physics of highly excited atoms being of fundamental and practical importance. In particular, evident advances were achieved in studies of the structure and spectra of highly excited atoms, their behavior in static electric and magnetic fields, interactions with electromagnetic ra diation, spectral-line broadening and the shift of Rydberg series, collisions with electrons, ions, atoms, and molecules, etc. The principle objective of the present book is to reflect the most important physical approaches and efficient theoretical techniques in the modem physics of highly excited atoms and ions.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 312 pp. Englisch.…

Neuware -Since 1981 there has been an attempt in Europe to organize a series of small meetings/workshops/tavole rotonde with the aim of bringing together physi cists and chemists interested in problems concerning atoms or molecules in teracting with external photons where the continua are investigated. The number of problems that fall into this category turns out to be vast. However, it is not possible to make a strict separation into problems con cerning atomic and molecular collisions and those related to the usual spec troscopy. This admixture of two disciplines, discussions on the role of photons and on the interaction of external electromagnetic fields with the continuum provided a central motivation for these workshops. The fourth of this series of meetings was held at Cortona between June 16 and 20, 1986. It was attended by about 100 researchers in the field and there were 43 presentations, all having equal time. These talks form the subject matter of this volume. The idea of publishing the proceedings of these meetings is not new. It allows one to have small meetings in which the subject matter can be discussed at length in a lively atmosphere. However, after the meeting is over, the speakers can collect their thoughts and produce articles in which the results of their interaction with the other participants can be incorporated.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 304 pp. Englisch.…

Neuware -In 1985, Kary Mullis was driving late at night through the flowering buckeye to the ancient California redwood forest, cogitating upon new ways to sequence DNA. Instead he came upon a way to double the number of specific DNA modules, and to repeat the process essentially indefinitely. 1 He thought of using two oligonucleotide sequences, oppositely oriented, and a DNA polymerase enzyme, to double the number of DNA targets. Each product would thene become the target for the next reaction, effectively yielding a product which doubled in quantity with each repeated cycle. Like the chain reaction leading to nuclear fission, with each cycle event each initial reactant (neutron or DNA molecule) yields two similar products, each of which can serve as the initial reactant. The invention of this exponentially increasing amplification system quickly became known as the polymerase chain reaction (PCR). The tremendous sensitivity of PCR ultimately resides in the necessity for each of two specific oligonucleotide annealing reactions to occur at the same time in the proper orientation. The DNA annealing reaction is a very specific reaction. Single genes have been detected by hybridization of a DNA probe to chromosome preparations together with sensitive fluorescence microscopy. This is the equivalent to detecting a gene present in a single copy per cell genome. It is the combination of two such specific annealing reactions which makes possible the amplification needed to detect a single molecule with a specific DNA sequence in over 100,000 cell genomes.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 396 pp. Englisch.…

Neuware -This is the first book in a new series - 'Materials Research and Engineering' - devoted to the science and technology of materials. 'Materials Research and Engineering' evolves from a previous series on 'Reine und Angewand te Metallkunde' ('Pure and Applied Metallurgy'), which was edited by Werner Koster until his eightieth birthday in 1976. Although the present series is an outgrowth of the earlier one, it should not and cannot be regarded as a continuation. There had to be a shift of scope - and a change in presentation as well. Metallurgy is no longer an isolated art and science. Rather, it is linked by its scientific basis and tech nological implications to non-metallic and composite materials, as well as to processes for production, refining, shaping, surface treatment, and appli cation. Thus, the new series, 'Materials Research and Engineering', will present up-to-date information on scientific and technological progress, as well as on issues of general relevance within the engineering field and industrial society. Premiering the new series, the present book by Dieter Altenpohl gives the reader a very general outlook, in fact, a position analysis of materials and the materials industry within the framework of our contemporary technological environment. It ventures, moreover, to forecast the changes affecting this pattern in a dynamic, interdependent world. This may be an unusual way to start a scientific series - it is believed, nevertheless, to be an appropriate one.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 240 pp. Englisch.…

Neuware -A text surveying perturbation techniques and sensitivity analysis of linear systems is an ambitious undertaking, considering the lack of basic comprehensive texts on the subject. A wide-ranging and global coverage of the topic is as yet missing, despite the existence of numerous monographs dealing with specific topics but generally of use to only a narrow category of people. In fact, most works approach this subject from the numerical analysis point of view. Indeed, researchers in this field have been most concerned with this topic, although engineers and scholars in all fields may find it equally interesting. One can state, without great exaggeration, that a great deal of engineering work is devoted to testing systems' sensitivity to changes in design parameters. As a rule, high-sensitivity elements are those which should be designed with utmost care. On the other hand, as the mathematical modelling serving for the design process is usually idealized and often inaccurately formulated, some unforeseen alterations may cause the system to behave in a slightly different manner. Sensitivity analysis can help the engineer innovate ways to minimize such system discrepancy, since it starts from the assumption of such a discrepancy between the ideal and the actual system.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 240 pp. Englisch.…

Neuware -Engineering structures for reliable function and safety have to be designed such that operational mechanical loads are compensated for by stresses in the components bearable by the materials used. Vhat is 'bearable' First of all it depends on the properties of the chosen materials as well as on several other parameters, e.g. temperature, corrosivity of the environment, elapsed or remaining serviceable life, unexpected deterioration of materials, whatever the source and nature of such deterioration may be: defects, loss of strength, embrittlement, wastage, etc. DEFECTS and PROPERTIES of materials currently determine loadability. Therefore in addition to nondestructive testing for defects there is also a need for nondestructive testing of properties. The third type of information to be supplied by nondestructive measurement pertains to STRESS STATES under OPERATIONAL LOADS, i.e. LOAD-INDUCED plus RESIDUAL STRESSES. Residual stresses normally cannot be calculated; they have to be measured nondestructively; well-approved elastomechanical finite element codes are available and used for calculating load-induced stresses; for redundancy and reliability, engineers, however, need procedures and instrumentation for experimental checks.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 916 pp. Englisch.…
