Die Konjunktur springt an. Wird die Diskussion urn den Standort Deutschland verstummen? Sieher nieht. Der technologische Trend bleibt weiterhin die Arbeitsrationalisierung. Das gilt weItweit. Die qualend hohe Arbeitslosigkeit und die Angst davor bleiben im Land erhalten. Deutschland bleibt weiterhin verletzlich. Die Liberalisie­ rung des WeIthandels zwingt uns standiges Konkurrenzdenken auf. 1m wirtschaftlichen Konkurrenzdenken liegt Gefahr fU...

Das vorliegende Werk ist der erste Band einer dreibändigen Serie, die als Neuauflage des Buchs »Ziegler's Vorlesungen über Mechanik« konzipiert wird. Dieser erste Band behandelt nach einem einführenden Kapitel über Grundlagen (Kinematik, Kräfte, Leistung) die Statik, der zweite Band wird der Festigkeitslehre und der dritte der Dynamik gewidmet. Die Dreiteilung entspricht auch dem stoIDichen Inhalt einer dreisemestrigen Vorlesungsreihe, die Pro...

Je mehr wir über die Wirbelsäule erfahren, um so verblüffender erscheint uns dieses mechanische Wun­ derwerk! Die Frage taucht auf: «Warum leiden so viele Men­ schen an Rückenbeschwerden?» Die Antworten werden sich durch diesen Kurs Stein um Stein mosaikartig zusammenfügen. Auf viele Fragen werden Sie in diesem Ratgeber eine Antwort finden, wie z.B. 1& Wie ist die Wirbelsäule aufgebaut? 1& Welches sind die Schwachstellen der Wirbelsäule? 1& We...

Grätzer¿s 'General Lattice Theory' has become the lattice theorist¿s bible. Now we have the second edition, in which the old testament is augmented by a new testament. The new testament gospel is provided by leading and acknowledged experts in their fields. This is an excellent and engaging second edition that will long remain a standard reference." --MATHEMATICAL REVIEWS

Der Erhaltung vorhandener Bausubstanz und ihre Anpassung an neue Bedürfnisse kommt heute eine steigende Bedeutung zu. Das gilt auch für Tragkonstruktionen. Während Tragwerke in Stahl von vornherein anpassungfähiger sind, mussten entsprechende Möglichkeiten bei Betontragwerken erst geschaffen und entwickelt werden. Das nachträgliche Anbringen äußerer Bewehrung ist ein solches Verfahren. Mit diesem Verfahren ist es möglich, Mängel an bestehenden...

Intended for both researchers and practitioners, this book will be a valuable resource for studying and applying recent robust statistical methods. It contains up-to-date research results in the theory of robust statistics Treats computational aspects and algorithms and shows interesting and new applications.

Charles François Sturm was born in Geneva, Switzerland, on September 29, 1803. He obtained his scientific education in this city and began his rich scientific career there through significant research in sound propagation and compressibility of fluids. In September of 2003, on the occasion of the 200th anniversary of his birth, his home city honoured his worldwide recognition with a colloquium and workshop under the sponsorship of the Universi...

This book presents a self-contained introduction to the analytic foundation of a level set approach for various surface evolution equations including curvature flow equations. These equations are important in many applications, such as material sciences, image processing and differential geometry. The goal is to introduce a generalized notion of solutions allowing singularities, and to solve the initial-value problem globally-in-time in a gene...

This book contains a unique survey of the mathematically rigorous results about the quantum-mechanical many-body problem that have been obtained by the authors in the past seven years. It addresses a topic that is not only rich mathematically, using a large variety of techniques in mathematical analysis, but is also one with strong ties to current experiments on ultra-cold Bose gases and Bose-Einstein condensation. The book provides a pedagogi...

In this book an account of the growth theory of subharmonic functions is given, which is directed towards its applications to entire functions of one and several complex variables. The presentation aims at converting the noble art of constructing an entire function with prescribed asymptotic behaviour to a handicraft. For this one should only construct the limit set that describes the asymptotic behaviour of the entire function. All neces...

Rudolph Virchow (1821-1902) was a leading figure in the medical, political and intellectual life of Germany in the second half of the nineteenth century. He became the most famous pathologist of his time, especially through his book "Cellular Pathology" – which discussed pathology in terms of the functioning of the cells in the anatomic lesions of diseases. Virchow's writings were voluminous: he wrote many books and more than 2, 000 articles ...

Recent developments in the field of occupational asthma research and clinical practice are the topic of this volume. The contribution of occupational exposures to chemical and biological agents to the burden of asthma in adults is clearly described in an overview of the most recent epidemiological data from both general population and industry based studies. Emphasis is put on powerful approaches like the use of apprentices studies, which incl...

This book is about relations between three different areas of mathematics and theoretical computer science: combinatorial group theory, cryptography, and complexity theory. It is explored how non-commutative (infinite) groups, which are typically studied in combinatorial group theory, can be used in public key cryptography. It is also shown that there is a remarkable feedback from cryptography to combinatorial group theory because some of the ...

Distributed computing paradigms for sharing resources such as Clouds, Grids, Peer-to-Peer systems, or voluntary computing are becoming increasingly popular. While there are some success stories such as PlanetLab, OneLab, BOINC, BitTorrent, and SETI@home, a widespread use of these technologies for business applications has not yet been achieved. In a business environment, mechanisms are needed to provide incentives to potential users for partic...

This book deals with the dynamics of general systems such as foliations, groups and pseudogroups, systems which are closely related via the notion of holonomy. It concentrates on notions and results related to different ways of measuring complexity of systems under consideration. More precisely, it deals with different types of growth, entropies and dimensions of limiting objects. Problems related to the topics covered are provided throughout ...

This is just...entropy, he said, thinking that this explained everything, and he repeated the strange word a few times. 1 ? Karel Capek , "Krakatit" This "strange word" denotes one of the most basic quantities of the physics of heat phenomena, that is, of thermodynamics. Although the concept of entropy did indeed originate in thermodynamics, it later became clear that it was a more universal concept, of fundamental signi?cance for chemistry an...

A contemporary of Christopher Wren, Robert Boyle, and Isaac Newton, and close friend of all but Newton, Robert Hooke (1635-1703), one of the founders of the early scientific revolution, faded into almost complete obscurity after his death and remained there for nearly three centuries. The result has been that his role in the scientific revolution has been almost totally ignored. He was best known as the first professional scientist worthy of t...

There have been tremendous advances in our understanding of molecular and tumor biology during the past few years. In the field of cancer therapeutics, it is expected that cytotoxic drug approaches will be gradually replaced with treatments based on biological targeted approaches. Hopefully these new targeted therapies will significantly increase efficacy and lack the devastating and troublesome side effects elicited by cytotoxic chemotherapy....
