    Note: Im Gegensatz zur Statik (Band 1), wo man es mit idealisierten, starren Körpern zu tun hat, muß in der Festigkeitslehre die Verformbarkeit der Körper berücksichtigt werden. Dabei geht es im wesentlichen um die Bestimmung von Spannungen und Verformungen infolge von Zug, Druck, Schub, Biegung und Torsion. Die einzelnen Spannungen werden zu einer (hypothetischen) Vergleichsspannung zusammengefaßt und den im Labor ermittelten Werkstoffdaten gegenübergestellt. Auf dieser Basis ist eine sichere und wirtschaftliche Dimensionierung der Bauteile möglich. Die Erfahrungen, die man aus bewährten Konstruktionen, aber auch aus Schadensfällen in der Praxis gewonnen hat, lassen sich mit den Formeln der Festigkeitslehre auf geometrisch ähnliche (oder durch modellmäßige Vereinfachung auch auf kompliziertere) Systeme mit genügender Genauigkeit übertragen. Ein ständiger Sollwert-Istwert-Vergleich bei der Planung, der Ausführung und dem Betrieb der Maschinen soll zu einer weitgehenden Optimierung der Bauteile führen, die vom Ingenieur durch fortwährende Berechungen und Messungen angestrebt wird. Die Gleichungen der Festigkeitslehre müssen alle Daten enthalten, die einen Einfluß auf die Spannungen und Verformungen haben konnen und sind somit komplizierter und umfangreicher als die der Statik. Maßgebend sind z. B. die Belastungsarten geometrische und physikalische Bedingungen wie Lage, Größe und Verteilung der Kräfte, Querschnitts-Abmessungen, Werkstoff­ Kennwerte, Temperatur-Einflüsse usw. Daher ist es wichtig, Wege und Mittel zu finden, um die komplexen Themen der Festigkeitslehre so einfach und anschaulich wie möglich zu entwickeln, ohne auf die mathematische Strenge bei der Ableitung und auf die Allgemeingültigkeit der Lösungen (Übertragung auf räumliche Probleme) zu verzichten

    Note: Der Ingenieur ist für die Konstruktion, Haltbarkeit und einwandfreie Funktion von technischen Bauteilen zuständig. Er muß für ausreichende Dimensionierung und für die Auswahl geeigneter Werkstoffe sorgen, damit die Bauteile genügend Festigkeit besitzen, um den teilweise hohen Belastungen mit Sicherheit standhalten zu können. Der Ingenieur beschäftigt sich also mit Kräften und deren Wirkung auf technische Systeme (Maschinen, Apparate, Fundamente, Gebäude usw.), wozu die Technische Mechanik die Grundlagen liefert. Um den richtigen Einstieg in dieses schwierige Gebiet zu finden, ist eine anschauliche, praxisorientierte Betrachtungsweise erforderlich, damit das Vorstellungsvermögen und das konstruktive Gefühl des Ingenieurs geweckt und gefördert wird. Wie überall in der Technik hat der Computer auch in der Mechanik die Rechenmethoden stark beeinflußt und eine weitgehende Vertiefung und Schematisierung ermöglicht. Von einem modernen Ingenieur wird daher verlangt, daß er sich mit der Handhabung des Computers vertraut macht. In der Hauptsache werden also an den Ingenieur zwei Forderungen gestellt. Zum einen muß er sich mit anschaulichen, klaren, übersichtlichen Gedanken und Vorstellungen in technische Probleme hineinversetzen konnen, zum anderen muß er auch zu einer abstrakten und schematischen Denkweise fähig sein. Die Lehrmittel für die Ausbildung der Ingenieure müssen diesen Forderungen gerecht werden und sowohl durch anschauliche zeichnerische als auch durch abstrakte rechnerische Vorgehensweise den Stoff vermitteln. Die Themen sollen so anschaulich wie möglich entwickelt werden, wobei an Skizzen nicht gespart werden darf. Sind doch gerade die Zeichnungen in Verbindung mit den mathematisch-physikalischen Formeln die eigentliche Sprache und das wichtigste Ausdrucksmittel des Ingenieurs

    Note: Dieses als Kompendium konzipierte Buch - mit Lehrbuchcharakter - vermittelt das Grundwissen über die äußere Beschaffenheit sowie die chemischen, physikochemischen und physikalischen Eigenschaften textiler Faserstoffe. Es ist in erster Linie für Ingenieure und Technologen gedacht, die mit der Herstellung, Verarbeitung oder dem Einsatz textiler Faserstoffe maßgebend betraut sind. Für sie ist es unumgänglich, sich ausreichend mit der chemisch-strukturellen Beschaffenheit, den zahlreichen Eigenschaften sowie den Struktur-Eigenschafts-Beziehungen der Fasern zu befassen. Es wird jedoch auch dem Studenten des Textil- und Bekleidungsfaches das notwendige Rüstzeug für das Studium vermitteln. Die nach Eigenschaftsgruppen untergliederten Faserarten werden in zahlreichen Tabellen und Diagrammen einander gegenübergestellt. Dem Charakter des Nachschlagewerkes wird auch durch umfangreiche Literaturhinweise Rechnung getragen. Anwendungsbeispiele aus Forschung und industrieller Praxis sind zum besseren Verständnis eingeflochten. Dieses Kompendium wird sowohl dem angehenden wie dem bereits im Beruf stehenden Textiltechnologen, der in konkreten Verarbeitungssituationen und Einsatzfragen sachgerechte Entscheidungen fällen muß, von unschätzbarem Wert sein

    Content: The Fifth Purdue International Symposium on Statistical Decision The­ was held at Purdue University during the period of ory and Related Topics June 14-19,1992. The symposium brought together many prominent leaders and younger researchers in statistical decision theory and related areas. The format of the Fifth Symposium was different from the previous symposia in that in addition to the 54 invited papers, there were 81 papers presented in contributed paper sessions. Of the 54 invited papers presented at the sym­ posium, 42 are collected in this volume. The papers are grouped into a total of six parts: Part 1 - Retrospective on Wald's Decision Theory and Sequential Analysis; Part 2 - Asymptotics and Nonparametrics; Part 3 - Bayesian Analysis; Part 4 - Decision Theory and Selection Procedures; Part 5 - Probability and Probabilistic Structures; and Part 6 - Sequential, Adaptive, and Filtering Problems. While many of the papers in the volume give the latest theoretical developments in these areas, a large number are either applied or creative review papers.

    Series Statement: Springer Texts in Statistics,
    Content: These notes were written as a result of my having taught a "nonmeasure theoretic" course in probability and stochastic processes a few times at the Weizmann Institute in Israel. I have tried to follow two principles. The first is to prove things "probabilistically" whenever possible without recourse to other branches of mathematics and in a notation that is as "probabilistic" as possible. Thus, for example, the asymptotics of pn for large n, where P is a stochastic matrix, is developed in Section V by using passage probabilities and hitting times rather than, say, pulling in Perron­ Frobenius theory or spectral analysis. Similarly in Section II the joint normal distribution is studied through conditional expectation rather than quadratic forms. The second principle I have tried to follow is to only prove results in their simple forms and to try to eliminate any minor technical com­ putations from proofs, so as to expose the most important steps. Steps in proofs or derivations that involve algebra or basic calculus are not shown; only steps involving, say, the use of independence or a dominated convergence argument or an assumptjon in a theorem are displayed. For example, in proving inversion formulas for characteristic functions I omit steps involving evaluation of basic trigonometric integrals and display details only where use is made of Fubini's Theorem or the Dominated Convergence Theorem.

    Content: During the winter term 1987/88 I gave a course at the University of Bonn under the title "Manifolds and Modular Forms". I wanted to develop the theory of "Elliptic Genera" and to learn it myself on this occasion. This theory due to Ochanine, Landweber, Stong and others was relatively new at the time. The word "genus" is meant in the sense of my book "Neue Topologische Methoden in der Algebraischen Geometrie" published in 1956: A genus is a homomorphism of the Thorn cobordism ring of oriented compact manifolds into the complex numbers. Fundamental examples are the signature and the A-genus. The A-genus equals the arithmetic genus of an algebraic manifold, provided the first Chern class of the manifold vanishes. According to Atiyah and Singer it is the index of the Dirac operator on a compact Riemannian manifold with spin structure. The elliptic genera depend on a parameter. For special values of the parameter one obtains the signature and the A-genus. Indeed, the universal elliptic genus can be regarded as a modular form with respect to the subgroup r (2) of the modular group; the two cusps 0 giving the signature and the A-genus. Witten and other physicists have given motivations for the elliptic genus by theoretical physics using the free loop space of a manifold.

    Series Statement: Nonlinear Topics in the Mathematical Sciences, An International Book Series dealing with Past, Current and Future Advances and Developments in the Mathematics of Nonlinear Science, 1
    Content: This is the first volume of a series of books that will describe current advances and past accompli shments of mathemat i ca 1 aspects of nonlinear sCience taken in the broadest contexts. This subject has been studied for hundreds of years, yet it is the topic in whi ch a number of outstandi ng di scoveri es have been made in the past two decades. Clearly, this trend will continue. In fact, we believe some of the great scientific problems in this area will be clarified and perhaps resolved. One of the reasons for this development is the emerging new mathematical ideas of nonlinear science. It is clear that by looking at the mathematical structures themselves that underlie experiment and observation that new vistas of conceptual thinking lie at the foundation of the unexplored area in this field. To speak of specific examples, one notes that the whole area of bifurcation was rarely talked about in the early parts of this century, even though it was discussed mathematically by Poi ncare at the end of the ni neteenth century. I n another di rect ion, turbulence has been a key observation in fluid dynamics, yet it was only recently, in the past decade, that simple computer studies brought to light simple dynamical models in which chaotic dynamics, hopefully closely related to turbulence, can be observed.

    Content: Rural development is linked crucially with rural structure, though the latter is often difficult to analyse. This book analyses rural classes and the diverse relations between producers in order to understand the relationship between Third World farmers and the international economy, and the significance of this for development and underdevelopment. The author introduces a number of theoretical distinctions and devises a systematic framework which is applied to the analysis of a range of rural producers. The book assesses a number of strategies employed in planned development in the light of their implications for rural social structure, and thus for development in the Third World. This book provides an intensive and original conceptual and practical discussion of the possibilities for development under capitalism, and will be of interest to economists, political scientists and sociologists, as well as those working in development studies.
