Annotation Provides materials engineers and scientists with a comparative listing of materials and their magnetic and electrical properties to aid in the materials selection process. The materials are sorted by a common materials hierarchy, and their property values are given in a consistent system of International Standard and customary units. The quality of the data and source of the data also are given to enable the user to assess the data. The 36 tables survey volume conductivity at ambient temperature, volume resistivity at high and low temperatures, thermal coefficient of resistivity, superconductors, relative permeability, coercive force, peak induction, residual induction, and curie temperature.

This is the first point of reference for the communications industries. It offers an introduction to a wide range of topics and concepts encountered in the field of communications technology. Whether you are looking for a simple explanation, or need to go into a subject in more depth, the Communications Technology Handbook provides all the information you need in one single volume. This second edition has been updated to include the latest technology including: Video on Demand Wire-less Distribution systems High speed data transmission over telephone lines Smart cards and batteries Global positioning Systems The contents are ordered initially by communications systems. This is followed by an introduction to each topic and goes on to provide more detailed information in alphabetical order. Every section contains an explanation of common terminology, and further references are provided. This approach offers flexible access to information for a variety of readers. Those who know little about communications professionals, the book constitutes a handy reference source and a way of finding out about related technologies. The book addresses an international audience by referring to all systems and standards throughout. This book has been revised to include new sections on: * Video on demand * Wire-less distribution systems * High speed data transmission over telephone lines * Smart cards * Global positioning systems * provides a basic understanding of a wide range of topics * offers a flexible approach for beginners and specialists alike * addresses an international audience by referring to all systems and standards throughout
