The contributions to this volume cover a wide spectrum of recent developments in geophysical data inversion, including basic mathematics and general theory, numerical methods, as well as computer implementation of algorithms. Most of the papers are motivated by problems arising from geophysical research and applications both on a global scale and with respect to local geophysical surveys, underlining the increasing importance of geophysical exploration methods in various fields, such as structural geology, prospecting for mineral and energy resources, hydro geology, geotechnology, environmental protection and archaeology. The first section of the book deals with basic mathematics and general theory underlying geophysical data inversion. Papers presented here are concerned with stabilization algorithms to solve ill-posed inverse problems, sensitivity of kernel function estimations to random data errors and reduction of errors in inverse modelling of response functions by linear constraints, numerical procedures for approximating the solution to boundary value problems, accuracy and stability of inverse ill-posed problems constituted by problems of moments, and fast Fourier transforms for solving potential field problems. The second section contains papers on gravity and magnetics, dealing with the solvability of the inverse gravimetric problem for sources represented by point masses and other elementary, solution of the inverse problem in cases of nonuniformly distributed data as obtained by palaeomagnetic studies, satellite observations, and surface projections of buried archaeological targets by inverse filtering of geomagnetic data."

Seismology in the sense of earthquake research is no longer exclusively a matter of earthquake recording and the analysis of seismograms. The tremendous progress in earth- quake dynamic research, the development of sophisticated technologies, the advent of the space age, and the call for reduction of the earthquake hazards and for disaster pre- vention programs have spurred interdisciplinary research to discover the earthquake generating processes. The progress in observing the physical phenomena of earthquake generating processes and the identification of earthquake precursors among these phe nomena have placed research on the field of predicting earthquakes on the solid basis of exact earth sciences. The measurement of the phenomena of slow-motion dynamics such as the move- ment of tectonic plates, the accumulation of strain, displacements observed in fault zones, and the temporal variations of physical rock properties fall into the domain of geodesists and geophysicists rather than seismologists. However, seismology in the broadest interpretation of earthquake research requires all observable phenomena of slow-motion dynamics in order to constrain models of focal mechanism and to penetrate deeper into earthquake source physics. Interdisciplinary research is on the way to open us new dimensions in earthquake and earthquake predic- tion research.

SAP is the world's leading provider of ERP software and services, with worldwide revenue in 2004 of $9.7 billion and a 57 percent market share among major business application providers; it is one of the world's largest software companies overall. ERP is a flexible, open technology platform that helps businesses run more efficiently (and profitably) by providing integrated management of key operations and supply chains. Written for IT professionals who find it hard to get through SAP's complex documentation, our book demonstrates how ERP can cut costs, provides a clear overview of how the ESA (enterprise service architecture) model affects ERP, and shows how to implement the new ERP in the real world. Topics covered include reducing the cost of an existing IT backbone, using the new ERP to address a company's "pain points" and challenges, and proving the value of ERP through ROI (return on investment) and TCO (total cost of ownership) studies.

Das vorliegende Buch wendet sich in erster Linie an Sammler von Micromounts und Kleinstufen, wobei der "Normalstufen-Sammler" naturlich ebenfalls Anregungen erhalt. Es soll eine methodische und technische Anleitung zum Aufbau und zur Pflege einer Sammlung sein. Dazu werden entsprechende Hinweise zur sachgemassen Bergung der Stucke und speziellen Praparation gegeben sowie Bestimmungshilfen mit spezifischen Erlauterungen fur die Diagnose von Micromounts und Kleinstufen beschrieben. Auch die fotografische und zeichnerische Darstellung der Stucke wird erlautert."

Der Band dokumentiert den aktuellen Stand der Zeitschriftenforschung in Deutschland und gliedert sich in drei Hauptkapitel: "Zeitschriftenforschung heute" bietet in vier UEberblicksbeitragen Orientierungen zur Gesamtthematik; "Gattungsuntersuchungen" bilanziert den Forschungsstand, die Forschungskontinuitat und relevante Forschungslucken auf der Gattungsebene. In "Spezifische Erkenntnisinteressen" werden Ergebnisse der Zeitschriftenforschung benannt, die aus der Anwendung verschiedener Methoden resultieren.

The length of Aegean arc in south-west Turkey has been deter mined by the use of intermediate focal depth earthquakes which occurred between 1900-1985 in the south-west of Turkey (34.00- 38.00 Nand 27.00-32.00 E). Intermediate focal depth earthqua kes in south-west Turkey revealed the presence of a seismic Benioff zone caused by underthrusting of the African litho spheric plate by the Aegean arc. In order to determine the geometry of underthrustin%detailed epicenter maps of the in termediate depth earthquakes in south-west of Turkey were pre pared. It is known that these earthquakes brought great harm in the past. Investigation of time distribution of them will help to predict the occurrence of them in the future. These intermediate focal depth earthquakes can be differenti ated from deep ones by their micro- and macroseismic proper ties. Papazachos (1969) and Comninakis (1970) found that the foci of these earthquakes are in a zone underthrusting exten ding from the East Mediterranean to the Aegean arc. Morgan (1968) and Le pichori (1968) defined three plates which are important in East Mediterranean tectonics. These are the Afri ca, Arabic and Eurasian plates. They define wide earthquake belt on the boundaries between the African and Eurasian plate."
