Companies and institutions depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based. Business Continuity is the ability to do business under any circumstances and is an essential requirement faced by modern companies. Both concepts - High Availability and Disaster Recovery - are realized by redundant systems. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, and all given examples refer to UNIX and Linux Systems.

Product Description: Die integrativen Trends, die sich seit Jahren in Unternehmen bezüglich der IT abzeichnen, z. B. Single Point of Administration, erfordern neue Konzepte für Autorisierung und Authentisierung. Dieses Buch bietet eine ganzheitliche Darstellung von rollenbasierenden Zugriffskonzepten...read more

Product Description: This volume contains 21 research and survey papers on recent developments in the field of diophantine approximation, which are based on lectures given at a conference at the Erwin Schrödinger-Institute (Vienna, 2003). The articles are either in the spirit of more classical diophantine analysis or of a geometric or combinatorial flavor...read more

Product Description: High Performance Computing (HPC) is the area of supercomputers, the fastest and best systems of their time. Most supercomputers are used to solve scientific problems, be it weather forecasting, simulation of car crashes or wind tunnels, modeling of proteins in bio-chemical research, or for simulation of atom-bomb tests...read more

Product Description: The classical theory of dynamical systems has tended to concentrate on Z-actions or R-actions. In recent years, however, there has been considerable progress in the study of higher dimensional actions (i.e. Zd or Rd with d>1). This book represents the proceedings of the 1993-4 Warwick Symposium on Zd actions...read more (view table of contents, read Amazon.com's description)

Product Description: Corporate identity is a matter of urgent importance for all firms be they well established, changing on account of a merger or simply wishing to reinvent themselves. This book reports on the current European knowledge of the subject and illustrates the analysis with case studies of foremost companies...read more

Product Description: Although the study of dynamical systems is mainly concerned with single trans­ formations and one-parameter flows (i. e. with actions of Z, N, JR, or JR+), er­ godic theory inherits from statistical mechanics not only its name, but also an obligation to analyze spatially extended systems with multi-dimensional sym­ metry groups...read more
