Since a molecular-beam apparatus was first successfully used by Cho and Arthur in the late 1960s to crystallize and investigate GaAs epilayers, high vacuum epitaxial growth techniques using particle beams have developed rapidly. This development accelerated when different semiconductor devices with quantum­ well structures were invented in the 1970s. The important implementation of these structures in devices like quantum-well lasers, high ele...

- Behandelt den Einsatz von SAP-Systemen zur Unterstützung zwischenbetrieblicher Kooperationen - Geht intensiv sowohl auf klassische Lösungen wie EDI als auch auf moderne Systeme wie SAP APO, SAP LES, SAP BBP, Business Information Warehouse sowie Internet Applications ein. - Enthält mehrere ausführliche Fallstudien zum Einsatz von SAP-Systemen in der Praxis.

This text is concerned with a probabilistic approach to image analysis as initiated by U. GRENANDER, D. and S. GEMAN, B.R. HUNT and many others, and developed and popularized by D. and S. GEMAN in a paper from 1984. It formally adopts the Bayesian paradigm and therefore is referred to as 'Bayesian Image Analysis'. There has been considerable and still growing interest in prior models and, in particular, in discrete Markov random field methods....

4 lation and optimization. These are essential constituents of the iterative process, leading to a feasible and, one hopes, optimal design. 1.3 Content of the Book In Chapter 2 we present briefly the history of CAD. The main components of CAD systems are identified, and their principal functions described. Economi­ cal and interdisciplinary aspects are discussed. Chapter 3 starts with a systems analysis of the design process. The notion of a p...

Given the continuing high level of concern among health professionals and the general public about issues related to AIDS, this volume on testing for AIDS and related viruses is extremely timely. The book has been written by experts in the area of AIDS testing, many of whom are at the Centers for Disease Control. The book includes several chapters which compare the different laboratory tests available for detecting the AIDS virus (HIV). It als...

Although the purpose and scope of this monograph remain unchanged, I have been obliged to revise and rewrite many sections to keep pace with the recent growth in knowledge of endometrial pathology and physiology. New knowledge emanates from every quarter, engendered by improved meth­ ods of study in virtually every subspecialty, by exemplary cooperation between disciplines, and especially by the exchange of ideas internationally. On the other ...

The regenerative capacity of the liver cell is almost unlimited. Therefore after acute liver damage, be it viral, toxic, hypoxic, or surgical in origin, restitutio ad integrum is the usual outcome. In two forms of liver disease, however, this is not the case: in fulmi­ nant hepatic failure, liver regeneration often is not fast enough to keep the organism alive, in end-stage cirrhosis, regeneration is dis­ turbed by a hypertrophic architecture ...

The current book represents a distillation of the experience gained in diagnosis of intracranial tumors with computed X-ray tomography at the University Hos­ pitals of Berlin, Mainz, and Miinchen. To what purpose? Standard radiological techniques such as pneumoencephalography with lumbar puncture and cerebral arteriography with puncture of the common carotid artery are invasive proce­ dures which entail a certain amount of risk as well as disc...

Pamela Hansford Johnson was born in 1912 and gained recognition with her first novel, This Bed Thy Centre, published in 1935. She wrote 27 novels. Her themes centred on the moral responsibility of the individual in their personal and social relations. The fictional genres she used ranged from romantic comedy (Night and Silence, Who Is Here?) and high comedy (The Unspeakable Skipton) to tragedy (The Holiday Friend) and the psychological study o...

This textbook is based on a lecture course in synergetics given at the University of Moscow. In this second of two volumes, we discuss the emergence and properties of complex chaotic patterns in distributed active systems. Such patterns can be produced autonomously by a system, or can result from selective amplification of fluctuations caused by external weak noise. Although the material in this book is often described by refined mathematical ...

ZUR ERSTEN ENGLISCHEN AUFLAGE Die plastische Chirurgie entstand - wie auch andere operative Spe­ zialfacher - durch die Anstrengungen einer kleinen Gruppe von En­ thusiasten, die durch Anwendung einer besonders verfeinerten Technik schon bald das Niveau der operativen Kunstfertigkeit in ei­ nem eng umgrenzten Betatigungsfeld zu sehr groBer EffIzienz ent­ wickelten. Seit dem Krieg wurden die Techniken, die in erster Linie zur Verdek­ kung von G...

Boden-, Luft- und Grundwasserverunreinigungen durch gesundheitsgefährdende Abfallstoffe z.B. durch Ablagerung auf industriell genutzten Flächen und auf Deponien oder durch Lekkagen von Tanklagern, Rohrleitungen oder Abwasserkanälen sind in vielen industrialisierten Ländern zu einem ernsten Problem geworden. Ein in Wissenschaft und Praxis der Sanierung von Altlasten, z.B. Deponien, Altablagerungen, alte Industriestandorte, erfahrenes Herausgebe...

A first hand account of the on-line revolution that created the PCG and the fight against IR35.

The Complete Clarksburg Ohio World War II Guide is one of the country's most thorough case studies analyzing one village's involvement during WWII. Research, letters, a veteran index, and over 80 photographs highlight the service of 222 veterans from Clarksburg who served our country and details a number of experiences from training to battle. Clarksburg sent one-in-five of its residents to war when the national average was one-in-eight, and ...
