Buch. Condizione: Neu. Neuware - The design of asynchronous circuits is increasingly important in solving problems such as complexity management, modularity, power consumption and clock distribution in large digital integrated circuits. Since the second half of the 1980s asynchronous circuits have been the subject of a great deal of research following a period of relative oblivion. The lack of interest in asynchronous techniques was motivated by the progressive shift towards synchronous design techniques that had much more structure and were much easier to verify and synthesize. System design requirements made it impossible to totally eliminate the use of asynchronous circuits. Given the objective difficulty encountered by designers, the asynchronous components of electronic systems, such as interfaces, became a serious bottleneck in the design process. The use of new models and some theoretical breakthroughs made it possible to develop asynchronous design techniques that were reliable and effective. Algorithms for Synthesis and Testing of Asynchronous Circuits describes a variety of mathematical models and of algorithms that form the backbone and the body of a new design methodology for asynchronous design. The book is intended for asynchronous hardware designers, for computer-aided tool experts, and for digital designers interested in exploring the possibility of designing asynchronous circuits. It requires a solid mathematical background in discrete event systems and algorithms. While the book has not been written as a textbook, it could nevertheless be used as a reference book in an advanced course in logic synthesis or asynchronous design. Algorithms for Synthesis and Testing of Asynchronous Circuits also includes an extensive literature review, which summarizes and compares classical papers from the 1960s with the most recent developments in the areas of asynchronous circuit design testing and verification. The validity and utility of employment tests have become entangled in the debate over the 1991 Civil Rights Bill. Worried about compliance with new federal guidelines for test validity, and concerned about possible lawsuits, the business world became wary of pre-employment testing in the early 1980s, but the use of employment testing increased throughout that decade.

Taschenbuch. Condizione: Neu. Neuware - Modern philosophy has benefited immensely from the intelligence and sensitivity, the creative and critical energies, and the lucidity of Polish scholars. Their investigations into the logical and methodological founda tions of mathematics, the physical and biological sciences, ethics and esthetics, psychology, linguistics, economics and jurisprudence, and the social sciences - all are marked by profound and imaginative work. To the centers of empiricist philosophy of science in Vienna, Berlin and Cambridge during the first half of this century, one always added the great school of analytic and methodological studies in Warsaw and Lw6w. To the world centers of Marxist theoretical practice in Berlin, Moscow, Paris, Rome and elsewhere, one must add the Poland of the same era, from Ludwig Krzywicki (1859-1941) onward. (From our preface to Wiatr [1979p. Other movements also have been distinctive in Poland. Phenomenology was developed in the impressive school of Roman Ingarden at Cracow, semiotics from the early work of the philosopher and psychologist Kazimierz Twardowski at Lw6w in the 1890's, with masterful develop ment by his disciples Kotarbinski and Ajdukiewicz onward, conceptual foundations of physics in the incisive methodological reflections of Marian Smoluchowski, and mathematical logic from Jan I:.ukasiewicz and Stanislaw Lesniewski to Tarski, Mostowski, and many others.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Transformation geometry is a relatively recent expression of the successful venture of bringing together geometry and algebra. The name describes an approach as much as the content. Our subject is Euclidean geometry. Essential to the study of the plane or any mathematical system is an under standing of the transformations on that system that preserve designated features of the system. Our study of the automorphisms of the plane and of space is based on only the most elementary high-school geometry. In particular, group theory is not a prerequisite here. On the contrary, this modern approach to Euclidean geometry gives the concrete examples that are necessary to appreciate an introduction to group theory. Therefore, a course based on this text is an excellent prerequisite to the standard course in abstract algebra taken by every undergraduate mathematics major. An advantage of having nb college mathematics prerequisite to our study is that the text is then useful for graduate mathematics courses designed for secondary teachers. Many of the students in these classes either have never taken linear algebra or else have taken it too long ago to recall even the basic ideas. It turns out that very little is lost here by not assuming linear algebra. A preliminary version of the text was written for and used in two courses-one was a graduate course for teachers and the other a sophomore course designed for the prospective teacher and the general mathematics major taking one course in geometry. 256 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From the beginning, the systems research movement has shown a high potential for offering a conceptual framework for the understanding of social systems. Much of this potential has been realized, but a major gap remains with regard to operational investigative aids. Developments of the last ten years with a method ological orientation and emphasis seem finally to be filling this gap. The purpose of this book is to describe the most advanced of these developments and to make them available to a wider audience. The emphasis is on developments that are primarily oriented toward interaction with expertise in the social sciences and that thus hold the most promise for social systems investigation. In particu lar, attempts have been made to provide substantiation and illustration of three main points: (1) the common motivation and essential integrability that systems research provides for developments and considerations along a very broad spec trum of interests; (2) the very diverse nature of the types and forms of considera tions that may be meaningfully integrated; and (3) the operational and usable nature that developments in systems methodology represent for research in the social sciences. The book is divided into three parts with a generally increasing degree of specificity. The first part (Chapters 1, 2, and 3) deals with foundational issues associated with modeling and methodology as areas worthy of study in their ix X PREFACE own right. 208 pp. Englisch.

Thomas In normal subjects the regulatory apparatus of the immune system permits responses to foreign antigens but suppresses those directed to 'self' components. Autoimmune disease occurs as a failure ofthis system either as a result of a primary defect in the regulatory apparatus (primary autoimmunization) or because of a change in the antigenicity of the tissues (secondary autoimmunization). Autoaggressive reactions are characterised by the presence of autoantibodies. When these are directed to membrane displayed antigens (Fig. 1) they are probably of importance in the lysis of hepatocytes. Those directed to cytoplasmic antigens may be useful diagnostically but are of unknown pathogenic significance. When no extrinsic aetiological factor can be identified, the process is assumed to be the result of a failure ofthe regulatory system, allowing the spontaneous expansion of a clone of autoreactive lymphocytes. The defect may be generalised or specific to certain groups of self-antigens and thus the autoimmune disease may be either multi- or unisystemic. The recent development of techniques to enumerate and measure the functional activity of the suppressor lymphocytes which control the effector limbs of the immune system has enabled investigators to test whether the various purported autoimmune diseases do have as their basis a generalised defect in immunoregu lation. Assessment of antigen-specific immunoregulatory function is, however, not yet readily available. liver Membrane I Antigen (LIM) I Liver I HLA, A, B, C, Sensitisation to Specific -;::!IIIL. . 220 pp. Englisch.

A realistic assess ment of the likely performance of coke should also take into consideration its resistance to degradation in the chemical and thermal environment of the blast furnace. A test is, therefore, needed which simulates as far as possible the mechanical, chemical and thermal conditions of the smelting process and measures the resultant changes in size distribution of the coke, and hence in its bulk permeability to gas flow, using representative samples of the feed coke as charged to the furnace. Moreover, new developments in coke production make it necessary to reassess coke testing so as to guide the coke producer in making the best use of available coals. The mode of mechanical coke breakage at ambient temperature has been extensively characterised and related to changes in the coke's bulk permeability(3). In contrast, the causes of deterioration in the hot strength and size of bulk coke arising from its partial gasification with carbon dioxide and reheating to high temperature are relatively less explored. The present paper describes the v. 352 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In 1949, the Dutch anatomist Jan Boeke was able to write: 'The socalled interstitial cells . . . which lie at the end of the sympathetic endformation as a connecting link between the nervous endformation and the effector cells, are . . . shown to be of pri mary importance for the transferring and the remoulding of the nervous stimulus . . . . ' And: ' . . . the problem of the interstitial cells and of the synapse is the most impor tant problem of neurohistology of the future. ' When Boeke wrote this, he advocated the generalized concept, holding that inter stitial cells were intercalated between autonomic nerves and effector cells. A frank illus tration of this is presented by Tinel (l937), who places interstitial cells of Cajal (ICC) as terminal neurons of all autonomic nerves (his Fig. 1). While there have been over 100 light microscopic investigations (Table 1) of ICC in tissues and organs other than intestine, none of these have been followed up by electron microscopic studies. It is important to bear in mind that when the term ICC is used today, the only reference tissue for which sufficient information (i. e. , including an ultrastructural identification) on the ICC is at hand is the intestine, or rather the muscularis externa of small inte stine (in Table 1, those contributions which relate to intestinal ICC are underlined). 144 pp. Englisch.

The fmdings elaborated, however, are not only of theoretical interest, but bear in addition great clinical implications. In clinical cardiology this became quite evident by the use of tracers in order to study myocardial perfuSion and by the deSCription of certain clinical entities - such as angina with normal coro nary arteries - which are best explained by 'disturbed microcirculation'. With respect to this new developing theoretical and clinical field of cardiac microcirculation it was the aim of the Microcirculation Working Group of the European Society of Cardiology to have a symposium on which all different but clinically relevant aspects of cardiac microcirculation will be covered. This symposium, held in Heidelberg in January 1980, was planned not only for the exchange of concepts and ideas, but was expected to be in addition partially a teaching session; the basic scientists should be directed toward a better under standing of the clinical problems, and the clinicians should learn more about the basic mechanisms regulating substrate and ion exchange in such an impor tant organ as the heart, and furthermore the theoretical limitations of some of the diagnostic and therapeutical procedures should be taught. Without a lot of help we would never have succeeded in organizing the sym posium and editing its results. 372 pp. Englisch.
