Part III brings out the relation between computer systems and operations research applications. This volume was designed and written for use in the operations research and management science community. Apart from the background provided by the first five chapters, the emphasis is on the computational tools, algorithms, languages, and systems that assist the problem solver.

  • Molecular Aspects of Transport Proteins

    • 1st Edition
    • Volume 21
    • J.J.H.H.M. de Pont
    • English
    The development of molecular biological techniques and their application in the field has given a new dimension to the area of membrane transport. The combination of biochemical (site-specific reagents), molecular biological (site-directed mutagenesis) and genetic approaches of which this volume gives numerous examples in combination with biophysical techniques as X-ray analysis and NMR will eventually lead to a complete elucidation of the mechanism of action of these transport proteins.Although impossible to give a comprehensive overview of this rapidly expanding field, the expert contributors discuss: pumps involved in primary active transport, carriers which transport metabolites, and channels which allow selective passive transport of particular ions.This volume is ideal for teachers, students and investigators in this field, and will lead to further progress in our understanding of this fascinating field.

  • Statistical Analysis of Regional Yield Trials: AMMI Analysis of Factorial Designs

    • 1st Edition
    • H.G. Gauch Jr.
    • English
    During the last few years, many journal articles have shown the usefulness of the Additive Main Effects and Multiplicative Interaction (AMMI) model for analyzing regional yield trials. AMMI helps agronomists and breeders in several ways: to understand or model complex data sets, especially the interactions; to estimate yields more accurately, even with less data; to make better selections; and to design more efficient yield-trial experiments.This book is the first systematic treatment of these topics, collecting concepts from the scattered literature and also presenting many new results. Although agricultural applications are emphasized here, AMMI is applicable to two-way data tables containing one kind of data, either replicated or not, so AMMI appears in many areas of science and technology.The volume's first seven chapters review the agricultural and statistical principles and the final chapter indicates the difference that AMMI can make for agricultural research and world food supplies. This book will be of great value to agricultural scientists throughout the world, enabling them to learn more from their data and thereby make greater progress.

  • Microwave Excited Plasmas

    • 1st Edition
    • Volume 4
    • M. Moisan + 1 more
    • English
    The contrasting examples of microwave plasmas given in this volume demonstrate their capability of not only covering the totality of expressed needs in that particular field, but in many others. For example the ions and reactive neutral species, indispensable for the synergetic effects in etching and deposition processes can be used in metallurgical treatment, and for materials processing in general. They also have the ability to dissociate molecules and excite atoms as required in analytical chemistry where the information on the constituent concentrations is obtained through optical spectroscopy or mass spectrometry. Finally, microwave plasmas can supply the photons for laser and lighting applications. It is noteworthy that microwave plasmas cover an impressive pressure range of eight orders of magnitude from 10-3 Pa (10-5 torr) to above atmospheric pressure. The versatility of microwave plasmas, their moderate cost, and their ease of implementation particularly appeal to the industrial entrepreneur. As well as providing a review of current developments, the work proposes a synthesis on microwave discharges, laying out the corresponding physical references without developing too much plasma theory. It will be of interest both to the user, who may not be overly concerned about plasma science, and to the plasma expert, who may wish to redirect his interest towards plasma applications, such as materials processing.

  • Sampling of Heterogeneous and Dynamic Material Systems

    Theories of Heterogeneity, Sampling and Homogenizing
    • 1st Edition
    • Volume 10
    • P.M. Gy
    • English
    Although sampling errors inevitably lead to analytical errors, the importance of sampling is often overlooked. The main purpose of this book is to enable the reader to identify every possible source of sampling error in order to derive practical rules to (a) completely suppress avoidable errors, and (b) minimise and estimate the effect of unavoidable errors. In short, the degree of representativeness of the sample can be known by applying these rules. The scope covers the derivation of theories of probabilistic sampling and of bed-blending from a complete theory of heterogeneity which is based on an original, very thorough, qualitative and quantitative analysis of the concepts of homogeneity and heterogeneity. All sampling errors result from the existence of one form or another of heterogeneity. Sampling theory is derived from the theory of heterogeneity by application of a probabilistic operator to a material whose heterogeneity has been characterized either by a simple scalar (a variance: zero-dimensional batches) or by a function (a variogram: one-dimensional batches). A theory of bed-blending (one-dimensional homogenizing) is then easily derived from the sampling theory. The book should be of interest to all analysts and to those dealing with quality, process control and monitoring, either for technical or for commercial purposes, and mineral processing. Although this book is primarily aimed at graduates, large portions of it are suitable for teaching sampling theory to undergraduates as it contains many practical examples provided by the author's 30-year experience as an international consultant. The book also contains useful source material for short courses in Industry.

  • Environmental Science Theory

    Concepts and Methods in a One-World, Problem-Oriented Paradigm
    • 1st Edition
    • Volume 52
    • W.T. de Groot
    • English
    Having no competitive works, this unique publication presents a single structure for the analysis, explanation and solution of environmental problems, regardless of their location, nature or scale.In this problem-oriented approach, a coherent framework interconnects the study of facts and values, environmental systems, social causes and ethical premises. Counterbalancing current biases, the author emphasizes the fundamental, normative, economic and social-scientific aspects of truly interdisciplinary environmental science. For instance, the normative side of environmental problems are often neglected, resulting in policy designs and evaluations containing inefficient mixtures of sophisticated models and poorly grounded normative premises; this is the first major study to enrich the field with more normative consistency and groundedness. It is also the first text to consistently identify the social causes of environmental problems, rather than focusing on the physical-scientific aspects, and thus design deeper and more effective policies. Furthermore, a tinge of post-modern thinking runs throughout the book, with special care being taken, however, to constantly keep in view the practical relevance of theory for problem-oriented work.The book will be of interest to environmental scientists and managers wishing to improve the consistency and depth of their work, to social scientists and geographers wishing to connect their discipline to the environmental problems field, and to general scientists interested in the connections between philosophy and practice.
