• Sommario/riassunto: Elements of 3D Seismology, third edition is a thorough introduction to the acquisition, processing, and interpretation of 3D seismic data. This third edition is a major update of the second edition. Sections dealing with interpretation have been greatly revised in accordance with improved understanding and availability of data and software. Practice exercises have been added, as well as a 3D seismic survey predesign exercise. Discussions include: conceptual and historical foundations of modern reflection seismology; an overview of seismic wave phenomena in acoustic, elastic, and porous media; acquisition principles for land and marine seismic surveys; methods used to create 2D and 3D seismic images from field data; concepts of dip moveout, prestack migration, and depth migration; concepts and limitations of 3D seismic interpretation for structure, stratigraphy, and rock property estimation; and the interpretation role of attributes, impedance estimation, and AVO. This book is intended as a general text on reflection seismology, including wave propagation, data acquisition, processing, and interpretation and will be of interest to entry-level geophysicists, experts in related fields (geology, petroleum engineering), and experienced geophysicists in one subfield wishing to learn about another (e.g., interpreters wanting to learn about seismic waves or data acquisition).

• Sommario/riassunto: Build your own intelligent agent system... Intelligent agent technology is a tool of modern computer science that can be used to engineer complex computer programmes that behave rationally in dynamic and changing environments. Applications range from small programmes that intelligently search the Web buying and selling goods via electronic commerce, to autonomous space probes. This powerful technology is not widely used, however, as developing intelligent agent software requires high levels of training and skill. The authors of this book have developed and tested a methodology and to

• Sommario/riassunto: Angela Merkel ist eine, Matthias Platzeck ist ebenso einer wie auch Wolfgang Thierse: Wendepolitiker. In der SPD sind viele gelandet, auch bei der CDU, bei den Bündnisgrünen hingegen gibt es sie kaum, in der Linkspartei kommen sie gar nicht vor. Auferstanden aus den Ruinen des vierzig Jahre währenden real existierenden Sozialismus auf ostdeutschem Boden, machten sie sich in den Wirren der Revolution von 1989 auf, die damalige DDR mitzugestalten, umzugestalten.Es handelt sich um typische Karrieren des Umbruchs. Man kennt sie, diese Karrieren, die scheinbar aus dem Nichts, aus den Trümmern der Umbruchs- oder, im Falle der alten Bundesrepublik, aus der Zusammenbruchsgesellschaft nach 1945 hervorgegangen sind. Und doch sind diese Karrieren singulär, waren und sind doch viele Wendepolitiker jenseits klassischer Karrierepfade binnen kürzester Zeit an die Spitzen der deutschen Volksparteien emporgestiegen. Was ist das Geheimnis des – teilweise auch nur vorübergehenden – Erfolgs dieses spezifisch ostdeutschen Politikertyps? Was hat beispielsweise die Wendepolitikerin Angela Merkel der bundesrepublikanischen politischen Avantgarde voraus, dass sie an die Spitze der CDU und ; schließlich der Regierung aufstieg? Auf Fragen wie diese gibt Michael Lühmann in seiner vorliegenden Studie erstmals unter einer verbindenden Klammer Antworten, indem er sich den biographischen Wurzeln der Protagonisten annähert, an das Leben in der DDR und den daraus resultierenden politischen Folgen.
