    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

    Content: Opening Remarks and spectral signatures which are manifested on satellite imagery data. The debut of satellite imaging systems on board This book aims to fill that gap. It is based on ex Landsat I in 1972 was a technological advance of perience gained in the past 14 years by me and considerable interest to earth scientists in general other members of the remote sensing and the and exploration geologists in particular. Two major structural analysis research groups at Exxon Pro uses were anticipated for the satellite data. First, it duction Research Company.

    Note: 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

    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
