This monograph is intended to provide a comprehensive description of the rela tion between kinetic theory and fluid dynamics for a time-independent behavior of a gas in a general domain. A gas in a steady (or time-independent) state in a general domain is considered, and its asymptotic behavior for small Knudsen numbers is studied on the basis of kinetic theory. Fluid-dynamic-type equations and their associated boundary conditions, together with their Knudsen-layer corrections, describing the asymptotic behavior of the gas for small Knudsen numbers are presented. In addition, various interesting physical phenomena derived from the asymptotic theory are explained. The background of the asymptotic studies is explained in Chapter 1, accord ing to which the fluid-dynamic-type equations that describe the behavior of a gas in the continuum limit are to be studied carefully. Their detailed studies depending on physical situations are treated in the following chapters. What is striking is that the classical gas dynamic system is incomplete to describe the behavior of a gas in the continuum limit (or in the limit that the mean free path of the gas molecules vanishes). Thanks to the asymptotic theory, problems for a slightly rarefied gas can be treated with the same ease as the corresponding classical fluid-dynamic problems. In a rarefied gas, a temperature field is di rectly related to a gas flow, and there are various interesting phenomena which cannot be found in a gas in the continuum limit.
This self-contained book is an up-to-date description of the basic theory of molecular gas dynamics and its various applications. The book, unique in the literature, presents working knowledge, theory, techniques, and typical phenomena in rarefied gases for theoretical development and application. Basic theory is developed in a systematic way and presented in a form easily applied for practical use. In this work, the ghost effect and non-Navier–Stokes effects are demonstrated for typical examples—Bénard and Taylor–Couette problems—in the context of a new framework. A new type of ghost effect is also discussed.
The production of multi layered thin films with sufficient reliability is a key technology for device fabrication in micro electronics. In the Co/Cu type multi layers, for example, magnetoresistance has been found as large as 80 % at 4. 2 K and 50 % at room temperature. In addition to such gigantic mag netoresistance, these multi layers indicate anti ferromagnetic and ferromag netic oscillation behavior with an increase in the thickness of the layers of the non magnetic component. These interesting properties of the new synthetic flmctional materials are attributed to their periodic and interracial structures at a microscopic level, although the origin of such peculiar features is not fully understood. Information on the surface structure or the number density of atoms in the near surface region may provide better insight. Amorphous alloys, frequently referred to as metallic glasses, are produced by rapid quenching from the melt. The second generation amorphous alloys, called "bulk amorphous alloys", have been discovered in some Pd based and Zr based alloy systems, with a super cooled liquid region at more than 120 K. In these alloy systems, one can obtain a sample thickness of several centime ters. Growing scientific and technological curiosity about the new amorphous alloys has focused on the fundamental factors, such as the atomic scale struc ture, which are responsible for the thermal stability with certain chemical compositions.
This is a systematic study of the sociological debate on postmodernity in the Japanese context. The volume consists of a collection of 12 papers that explore the idea of postmodernity primarily from sociological perspectives, covering a wide range of domains including work, feminism, communication, science and technology, social stratification, fine arts and literature. The contributors come from diverse disciplines ranging from sociology and history to political science and linguistics. They include advocates of postmodern theories and postmodernist analyses of Japanese society, as well as critics who argue that a suitable revised theory of modernity is still an adequate framework for comparing Japan and the West. Others take the view that an intermediate position might be more productive; that a qualified or provisional version of postmodern can throw new light on issues traditionally neglected by social theory. While the postmodernity debate has been carried out chiefly in the context of European and American experiences, this book aims to pave the way for the postmodernity question to be explored in the non-western but highly industrialized setting of Japan, and brings forward a series of open-ended questions about the bias in the debate. Written by academics based in universities in Japan and Australia, the volume itself is postmodern in its internal diversity and multi-cultural orientation.
The popular image of Japanese society is a steroetypical one - that of a people characterised by a coherent set of thought and behaviour patterns, applying to all Japanese and transcending time. Ross Mouer and Yoshio Sugimoto found this image quite incongruous during their research for this book in Japan. They ask whether this steroetype of the Japanese is not only generated by foreigners but by the Japanese themselves. This is likely to be a controversial book as it does not contribute to the continuing mythologising of Japan and the Japanese. The book examines contemporary images of Japanese society by surveying an extensive sample of popular and academic literature on Japan. After tracing the development of "holistic" theories about the Japanese, commonly referred to as the "group model", attention is focused on the evaluation of that image. Empirical evidence contrary to this model is discussed and methodological lacunae are cited. A "sociology of Japanology" is also presented. In pursuit of other visions of Japanese society, the authors argue that certain aspects of Japanese behaviour can be explained by considering Japanese society as the exact inverse of the portayal provided by the group model. The authors also present a multi-dimensional model of social stratification, arguing that much of the variation in Japanese behaviour can be understood within the framework as having universal equivalence.
