Buch. Zustand: Neu. Neuware - Models in system design follow the general tendency in electronics in terms of size, complexity and difficulty of maintenance. While a model should be a manageable representation of a system, this increasing complexity sometimes forces current CAD-tool designers and model writers to apply modeling t…echniques to the model itself. Model writers are interested in instrumenting their model, so as to extract critical information before the model is complete. CAD tools designers use internal representations of the design at various stages. The complexity has also led CAD-tool developers to develop formal tools, theories and methods to improve relevance, completeness and consistency of those internal representations. Information modeling involves the representation of objects, their properties and relationships. Performance Modeling When it comes to design choices and trade-offs, performance is generally the final key. However performance estimations have to be extracted at a very early stage in the system design. Performance modeling concerns the set of tools and techniques that allow or help the designer to capture metrics relating to future architectures. Performance modeling encompasses the whole system, including software modeling. It has a strong impact on all levels of design choices, from hardware/software partitioning to the final layout. Information Modeling Specification and formalism have in the past traditionally played little part in the design and development of EDA systems, their support environments, languages and processes. Instead, EDA system developers and EDA system users have seemed to be content to operate within environments that are often extremely complex and may be poorly tested and understood. This situation has now begun to change with the increasing use of techniques drawn from the domains of formal specification and database design. This section of this volume addresses aspects of the techniques being used. In particular, it considers a specific formalism, called information modeling, which has gained increasing acceptance recently and is now a key part of many of the proposals in the EDA Standards Roadmap, which promises to be of significance to the EDA industry. In addition, the section looks at an example of a design system from the point of view of its underlying understanding of the design process rather than through a consideration of particular CAD algorithms. Meta-Modeling: Performance and Information Modeling contains papers describing the very latest techniques used in meta-modeling. It will be a valuable text for researchers, practitioners and students involved in Electronic Design Automation.

Buch. Zustand: Neu. Neuware - `.a most significant addition to the literature on its subject.' - Roger Morgan, Professor of Political Science, European University Institute, Florence An unconventional overview of a new and normal Germany fifty years after World War 2 and five years after unification. The authors address the chal…lenges of ageing and migration to a tangled national identity; their impact on a cautious yet resilient society, and an inertial yet dynamic economy; and the frequently surprising ways Germans have learned to cope with one another, redefine and pursue their interests, and deal with a changing world after two dictatorships, two world wars, and one cold war.

Buch. Zustand: Neu. Neuware - Modern economic growth is characterized by structural changes based on the introduction of new technologies into economics. The replacement and renova tion of technologies in industrial environments undergoing technical change is clearly one of the key aspects of economic development. The mathematic…al modeling of evolutionary economics under technical change (TC) has been rigorously considered by many authors during last decades. There is a wide variety of economic approaches and models describing different aspects of technical change. Among these are the models of embodied technical progress [19], [35], [70], [129], endogenous growth models [94], [102], the models of technological innovations [31], [32], [41], and others. The perspective self organization evolutionary approach is developed in [20], [38], [122], [123], [124], [126], which unites the aspects of diffusion of new technologies, technological and behavioral diversity of firms, learning mechanisms, age-dependent effects, and other important features of real-life economics. On the whole, an interest in evolutionary economics has brought considerable progress in the description and conceptualization of the sources, characteristics, direction and effects of technical change [125]. However, the modeling and control of technology lifetime under technical change has received rather little attention in mathematical economics in con trary to other aspects of technical progress. The lifetime of technologies has rarely been formally treated as a part of more general mathematical theory of economic dynamics. A problem which is still to be resolved consists in establishing the rational strategies of technologies' replacement under various assumptions on the behavior of technical change.

Buch. Zustand: Neu. Neuware - IFIP's Working Group 2.7(13.4)\* has, since its establishment in 1974, con centrated on the software problems of user interfaces. From its original interest in operating systems interfaces the group has gradually shifted em phasis towards the development of interactive systems. The group has orga ni…zed a number of international working conferences on interactive software technology, the proceedings of which have contributed to the accumulated knowledge in the field. The current title of the Working Group is 'User Interface Engineering', with the aim of investigating the nature, concepts, and construction of user interfaces for software systems. The scope of work involved is: - to increase understanding of the development of interactive systems; - to provide a framework for reasoning about interactive systems; - to provide engineering models for their development. This report addresses all three aspects of the scope, as further described below. In 1986 the working group published a report (Beech, 1986) with an object-oriented reference model for describing the components of operating systems interfaces. The modelwas implementation oriented and built on an object concept and the notion of interaction as consisting of commands and responses. Through working with that model the group addressed a number of issues, such as multi-media and multi-modal interfaces, customizable in terfaces, and history logging. However, a conclusion was reached that many software design considerations and principles are independent of implemen tation models, but do depend on the nature of the interaction process.

Buch. Zustand: Neu. Neuware - Drug problems present sharp challenges for policing and democracy in the European Union. Harmonisation of anti-trafficking measures contrasts with diversity of local policies on drug users. 'Open drug scenes' trigger innovative but often volatile responses. This collection presents vivid experiences… of drug policy-making at city, regional and higher levels. For the future, beyond 1996, EU 'confederal' and 'intergovernmental' scenarios have distinct implications for drugs. Finally, international dimensions are explored - drug control through money laundering countermeasures, trade and development policies, security and EU enlargement.

Taschenbuch. Zustand: Neu. Neuware - This book is the culmination of some ten years' theoretical and empirical investigation. Throughout this period, we have come into contact with many who have stimulated our thinking, some of whom belong to the community of Mathematics Educators. Our membership of that community has challenged… us to make sense of some deep issues related to mathematical learning, especially the cognitive and pedagogical faces of mathematical meaning making. Alongside this community, we are privileged to have been part of another, whose members are centrally concerned both with mathematics and educa tion. Yet many of them might reject the label of Mathematics Educators. This community has historically been clustered around what is now called the Epistemology and Learning Group at the Massachusetts Institute of Technol ogy. Their work has focused our attention on cognitive science, ethnography, sociology, artificial intelligence and other related disciplines. Crucially, it has forced our awareness of the construction of computational settings as a crucial component of the struggle to understand how mathematical learning happens. We have sometimes felt that few have tried to span both communities. Indeed, an analysis of the references in the literature would, we are sure, reveal that the two communities have often ignored each other's strengths. One reason for writing this book is born of our hope that we might draw together Mathematics Educators and mathematics educators, and assist both communities in recognising that there are insights that might be derived from each other.

Buch. Zustand: Neu. Neuware - Input/Output in Parallel and Distributed Computer Systems has attracted increasing attention over the last few years, as it has become apparent that input/output performance, rather than CPU performance, may be the key limiting factor in the performance of future systems. This I/O bottleneck is caus…ed by the increasing speed mismatch between processing units and storage devices, the use of multiple processors operating simultaneously in parallel and distributed systems, and by the increasing I/O demands of new classes of applications, like multimedia. It is also important to note that, to varying degrees, the I/O bottleneck exists at multiple levels of the memory hierarchy. All indications are that the I/O bottleneck will be with us for some time to come, and is likely to increase in importance. Input/Output in Parallel and Distributed Computer Systems is based on papers presented at the 1994 and 1995 IOPADS workshops held in conjunction with the International Parallel Processing Symposium. This book is divided into three parts. Part I, the Introduction, contains four invited chapters which provide a tutorial survey of I/O issues in parallel and distributed systems. The chapters in Parts II and III contain selected research papers from the 1994 and 1995 IOPADS workshops; many of these papers have been substantially revised and updated for inclusion in this volume. Part II collects the papers from both years which deal with various aspects of system software, and Part III addresses architectural issues. Input/Output in Parallel and Distributed Computer Systems is suitable as a secondary text for graduate level courses in computer architecture, software engineering, and multimedia systems, and as a reference for researchers and practitioners in industry.

Buch. Zustand: Neu. Neuware - The advent of molecular biology and recombinant DNA technology has profoundly changed contemporary medicine. These new scientific tools have made it possible to identify and understand pathological mechanisms at cellular, subcellular and molecular levels which has added previously unimaginable novel… dimensions to the diagnosis, therapy and prevention of a rapidly increasing number of diseases of the liver and biliary system. The title of this book - Acute and Chronic Liver Diseases: Molecular Biology and Clinics - expresses this epochal progress in hepatology. A series of acute or chronic diseases of the liver has been chosen whose modern clinical management most eloquently reflects the impact of the new scientific insight gained from molecular biology. The book, the proceedings of the 87th Falk Symposium (X International Congress of Liver Diseases: Part II of the Basel Liver Week 1995) held in Basel, Switzerland, October 19-21, 1995, first presents an overview of the molecular pathology of the chosen disease, followed by discussions of the clinical inference which this new scientific information entails for diagnosis, management and therapy. This approach is expected to ease the readers' endeavour to connect basic to clinical science and to facilitate appreciation of the enormous progress but also the inherent limitations and arising questions which modern molecular biology has brought to clinical medicine.
