An Introduction to Satellite Communications

Tue, 12 Jun 2018 01:24:00 GMT

The aim of this book is to give a clear and concise exposition of the principles and practice of satellite communications by describing the development of communications-satellite services. It will be useful both to engineers who have worked in other fields of telecommunication and to students.

The book describes the development of communications satellite services and explains how satellites and earth stations have evolved to meet changing requirements. It deals in a simple but practical way with the physics and geometry of the geostationary orbit, and the construction and operation of satellites and launch vehicles. It gives a thorough analysis of the essential factors governing the quality of speech, data and television signals received via satellite. Particular attention is paid to growth areas in satellite communications, including analogue television transmission, digital methods of transmission of speech and data, the use of satellites for maritime, aeronautical and land-mobile communications and VSATs (very-small aperture terminals).

The GEC Research Laboratories 1919-1984

Tue, 12 Jun 2018 00:28:11 GMT

The Research Laboratories of the GEC were conceived in 1916, started work in 1919 and moved to their well-known buildings in Wembley in 1922.

This book deals with their activities from the beginnings until the end of 1984. The opening chapter describes their origins, organisation and philosophy, describing particularly the pattern set by Sir Clifford Paterson, the first Director, much of which was to continue after his death in 1948. The second chapter summarises the work of the Laboratories, decade by decade, while subsequent chapters are a series of essays covering particular subjects such as lamps and lighting, valves, communications and semiconductors. The diverse number of projects undertaken in the 1939-45 war are described, and other chapters deal with the substantial work on solid state physics in the 1950s and 1960s, the work on optical fibres and optical communications in the 1970s and 1980s, the many aspects of work on technology and engineering, and the vital supporting role of the work on materials characterisation. The final chapters deal with patents, publications and some statistics on the Laboratories.

SF6 Switchgear

Mon, 11 Jun 2018 23:55:43 GMT

This book provides an extensive review of recent developments in SF₆ Switchgear and covers fundamental properties of SF₆ interrupter types, characteristics and associated operating mechanisms, arc modelling and computer aided methods for interrupter design and evaluation. The impact of SF₆ Technology upon (i) Transmission Switchgear (ii) Distribution and Utility Switchgear and (iii) Regulations, Testing and Instrumentation is dealt with comprehensively.

Both authors are recognised experts in this sector and their complementary expertise and national/international standing via IEE, IEEE, DTI, CIGRE, Current Zero Club and other research activities has enabled them to prepare this authoritative review of recent developments in SF₆ Switchgear. The book, which contains over 300 key references and more than 150 illustrations is for a world market, specifically aimed at power engineers in the manufacturing and supply industries, teachers and students of electrical engineering involved in undergraduate or postgraduate programmes and professional short courses and seminars in Universities and Polytechnics.

Continuous Time Controller Design

Mon, 11 Jun 2018 21:12:10 GMT

This book covers theoretical methods for the design of continuous time controllers for linear multivariate systems. It is intended for use by those wishing to build on a first course in control systems, either to expand their knowledge as practising engineers or as postgraduate students doing higher degrees in control engineering.

Based on material used in graduate courses taught by Professor Balasubramanian at the University of New Brunswick, this book brings together state space and frequency domain design methods for linear multivariable systems. It compares their similarities and highlights the advantages or disadvantages of the various approaches for particular applications. Divided into eleven chapters this book covers in some depth: state space design methods, frequency domain methods for multivariable systems, characteristic locus desiqn methods and stochastic control problems.
