  • Digital Control of Electric Drives

    • 1st Edition
    • Volume 43

    • English
    The electromechanical systems employed in different branches of industry are utilized most often as drives of working machines which must be fed with electric energy in a continuous, periodic or even discrete way. Some of these machines operate at constant speed, others require wide and varying energy control. In many designs the synchronous cooperation of several electric drives is required in addition to the desired dynamic properties. For these reasons the control of the cooperation and dynamics of electromechanical systems requires the use of computers.This book adopts an unusual approach to the subject in that it treats the electric drive system on the one hand as an element of a control system and on the other as an element of a complex automatic system. These two trends in the development of the automatic control of electric drives have resulted in a volume that provides a thorough overview on the variety of different approaches to the design of control systems.

  • Molecular Immunology

    • 1st Edition
    • Volume 5

    Immune responses result from the activation of an elaborate network of interacting cells occurring in specific microenvironments. Attention in recent years has been focussed intensively on a number of issues. Included among these are: the developmental pathways of the two major types of lymphocytes, T and B cells; the nature of their specific receptors for antigen and of their various accessory surface molecules; the subsequent fate of the cells following encounter with antigen presented as such or on a variety of cells; and the function of the effector molecules produced after successful activation by antigen. The present volume is concerned with some of these issues, and also with their potential application to the control of autoimmune phenomena and parasitic infestations.

  • Multivariate Pattern Recognition in Chemometrics

    Illustrated by Case Studies
    • 1st Edition
    • Volume 9
    • R.G. Brereton
    • English
    Chemometrics originated from multivariate statistics in chemistry, and this field is still the core of the subject. The increasing availability of user-friendly software in the laboratory has prompted the need to optimize it safely. This work comprises material presented in courses organized from 1987-1992, aimed mainly at professionals in industry. The book covers approaches for pattern recognition as applied, primarily, to multivariate chemical data. These include data reduction and display techniques, principal components analysis and methods for classification and clustering. Comprehensive case studies illustrate the book, including numerical examples, and extensive problems are interspersed throughout the text. The book contains extensive cross-referencing between various chapters, comparing different notations and approaches, enabling readers from different backgrounds to benefit from it and to move around chapters at will. Worked examples and exercises are given, making the volume valuable for courses. Tutorial versions of SPECTRAMAP and SIRIUS are optionally available as a Software Supplement, at a low price, to accompany the text.

  • Modern Methods of Aquaculture in Japan

    • 2nd Edition
    • Volume 24
    • H. Ikenoue + 1 more
    • English
    Fish farming has increased in status equal to cattle farming as a source of food for mankind. In developing countries fish and shellfish provide inexpensive animal protein, while in developed countries aquaculture is expected to produce more fish and shellfish as a source of low-calorie protein for health conscious individuals. In such an era, knowledge of fish farming technologies of different countries, strongly influenced by cultural factors, is of valuable importance. The primary production techniques of fish farming in Japan described here have an emphasis on practical technology. This second edition reflects the changes in both quantity of production and technology in Japanese aquaculture. The statistics have been revised and the text rewritten to suit the current status of aquaculture in Japan; new aquaculture species have been included and discussions on marine ranching and biotechnology for aquaculture added.

  • Hydrostatic Lubrication

    • 1st Edition
    • R. Bassani + 1 more
    • English
    Hydrostatic lubrication is characterized by the complete separation of the conjugated surfaces of a kinematic pair, by means of a film of fluid, which is pressurized by an external piece of equipment. Its distinguishing features are lack of wear, low friction, high load capacity, a high degree of stiffness and the ability to damp vibrations.This book reviews the study of externally pressurized lubrication, both from the theoretical and the technical point of view, thereby serving the needs of both researchers as well as students and technical designers. In this connection, design suggestions for the most common types of hydrostatic bearings have been included, as well as a number of examples. A comprehensive bibliography is included with each chapter providing up to date references for more in depth coverage.

  • Shallow Water Hydrodynamics

    Mathematical Theory and Numerical Solution for a Two-dimensional System of Shallow-water Equations
    • 1st Edition
    • Volume 55
    • W.Y. Tan
    • English
    Within this monograph a comprehensive and systematic knowledge on shallow-water hydrodynamics is presented. A two-dimensional system of shallow-water equations is analyzed, including the mathematical and mechanical backgrounds, the properties of the system and its solution. Also featured is a new mathematical simulation of shallow-water flows by compressible plane flows of a special virtual perfect gas, as well as practical algorithms such as FDM, FEM, and FVM. Some of these algorithms have been utilized in solving the system, while others have been utilized in various applied fields. An emphasis has been placed on several classes of high-performance difference schemes and boundary procedures which have found wide uses recently for solving the Euler equations of gas dynamics in aeronautical and aerospatial engineering. This book is constructed so that it may serve as a handbook for practicians. It will be of interest to scientists, designers, teachers, postgraduates and professionals in hydraulic, marine, and environmental engineering; especially those involved in the mathematical modelling of shallow-water bodies.

    The Leeds-Lyon symposia have well established themselves in the tribological calendar. Industrial progress requires a better understanding of interfacial phenomena than now exists and it is exciting to see that the topics addressed in these proceedings volumes are at the forefront of progress in tribological research. These proceedings contain 61 papers written by authors from all over the world, covering the entire spectrum of wear particles. Of particular interest is the detailed consideration of a wide range of particle formations and detachments, as well as a close look at the physics and chemistry of the wear of mechanisms, together with other in-depth state-of-the-art analytical contributions.
