Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Kolmogorov Equations for Stochastic PDEs gives an introduction to stochastic partial differential equations, such as reaction-diffusion, Burgers and 2D Navier-Stokes equations, perturbed by noise. It studies several properties of corresponding transition semigroups, such as Feller and strong Feller properties, irreducibility, existence and uniqueness of invariant measures. In addition, the transition semigroups are interpreted as generalized solutions of Kologorov equations. 182 pp. Englisch.

Organizations are complex entities formed to ov- come various limitations of individual agencies, such as cognitive, physical, temporal and institutional limitations. There is a parallel between the complexity of organizations and multi-agent systems. Therefore, we explore the use of concepts, methods and techniques from human organizational design as architectural principles for multi-agent systems. Three research lines are presented: organizational modeling and coordination, interop- ability and agent models. Organizational modeling and coordination are concerned with how resources (i. e. agents) can be identi ed and related to each other. In order to have agents cooperate, several issues of interoperability have to be addressed. Agent models deal with the design of individual intelligent software agents, taking into account typical features of agent intelligence. Every (human) activity raises two challenges: division of labor and coordi- tion [Mintzberg, 1993]. Division of labor is the decomposition of work (or goals) into various distinct tasks. Coordination refers to managing relations between these tasks to carry out the work. The patterns of division of labor, responsibilities (people who do the work), clustering of responsibilities into units and coordination between units can be de ned by organizational structures [Galbraith, 1973]. The design of an organization should cover how one or more actors are engaged in one or more tasks, where knowledge, capabilities and resources are distributed. 204 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Our goal for this book is to examine the contemporary therapy of rheumatoid arthritis (RA) from the increasingly important perspective of impact upon quality of life, costs and long-term health outcomes. For too long the focus has been on short term, symptomatic, and surrogate indicator outcomes. Yet RA is a life-long disor der with the majority of impact on an individual patient many years following onset. Further, even in the short-term, researchers and rheumatologists have tended to emphasize measurements of disease activity such as joint counts, ESR and physi cian's opinion as to the amount of disease activity present. It is only relatively recently that measures of structural damage, quality of life and impact on broad domains of health have been given increasing emphasis. Also, the significance of early treatment of RA in order to optimise long-term outcomes has a relatively short history [1]. We have been focussed on the disease processes as surrogates for long term outcomes. Until the short-term process measures are validated as surrogates of long-term effects we should also turn our attention to outcomes of disease and the impact of our management on those outcomes [2). Inour view, this book is especially timely. We are at the dawn of a revolution in the management of RA and other complex immunological inflammatory disorders because their molecular, genetic and environmental mechanisms are being unrav elled. Inthe process, we are revealing a substantial number of novel and significant targets for pharmacotherapy. 343 pp. Englisch.
