Modern Personal Radio Systems

Tue, 12 Jun 2018 01:27:55 GMT

This topical book builds upon an earlier IEE text Personal & mobile radio systems, by the same editor, which set out the fundamental issues in a discipline that appeared to have global expansion potential. That potential has now become a reality, and something more than a new edition of the previous book was needed to bring it up to date. This book is completely new, drawing on the experience and the many intensive studies that have been concentrated in this field in the past five years.

The book gives a clear and detailed insight into the fundamental problems and solutions found in modern personal communications: service requirements, coverage problems, multipath interference, cellular architectures and signalling, network management, data and supplementary services, satellite services. In particular it describes the approach of the GSM methodology, as one of the most intensively developed standards, to some of these problems, although the same principles also apply to DCS 1800 and other technologies.

Low-power HF Microelectronics

Tue, 12 Jun 2018 00:50:51 GMT

This book presents a thorough and integrated treatment of key topics in the field of low-voltage, low-power, mixed-mode design for the manufacture of low-cost, high-performance, robust integrated circuits. It brings together innovative modelling, simulation and design techniques in CMOS, SOI, GaAs and BJT, optimally combining process, device and design knowledge of low-voltage, high-frequency systems, including smart sensors.

The book meets the needs of mixed-signal designers and reflects the rise in high-performance, ultra-low-power digital systems combined with wireless multimedia telecommunications. The text is supported throughout by realistic application examples from both industry and academia, and a wealth of references to literature including many Internet sources.

In addition to being an excellent reference work, the material is valuable to practising engineers and researchers in microelectronics, industrial and academic, as well as to senior students in this field.

The Correspondence of Michael Faraday

Tue, 12 Jun 2018 00:21:33 GMT

Michael Faraday (1791-1867) was one of the most important men of science in nineteenth century Britain. His discoveries of electromagnetic rotations (1821) and electro-magnetic induction (1831) laid the foundations of the modern electrical industry. His discovery of the magneto-optical effect and diamagnetism (1845) led him to formulate the field theory of electro-magnetism, which forms one of the cornerstones of modern physics.

These and a whole host of other fundamental discoveries in physics and chemistry, together with his lecturing at the Royal Institution, his work for the state, his religious beliefs and his lack of mathematical ability, make Faraday one of the most fascinating scientists ever.

All these aspects of his life and work, and others such as his illnesses, are reflected in his correspondence. This volume, in which nearly 75% of the letters are previously unpublished, covers most of the 1840s. During the early part of this period, Faraday's scientific productivity declined markedly, but in 1845 he discovered the magneto-optical effect and diamagnetism, which allowed him to argue for his views on the nature of matter. In his work for the state, Faraday conducted, with Charles Lyell, the inquiry into the Haswell Colliery disaster in 1844. Since the publication of Volume 2, Faraday's correspondence with Trinity House, previously thought destroyed, has been found. These letters illustrate the crucial role which Faraday played in the development of the lighthouse service in the middle third of the nineteenth century.

Major correspondents in this volume include the Astronomer Royal George Biddell Airy, the Irish chemist Thomas Andrews, the mathematician Charles Babbage, the Governor General of Canada Charles Bagot, the engineer Isambard Kingdom Brunel, the philanthropist Angela Burdett Coutts, the French Chemist Jean-Baptiste-Andre Dumas, the Secretary of Trinity House Jacob Herbert, Byron's daughter Ada Lovelace, the President of the Royal Institution the Duke of Northumberland, the Prime Minister Robert Peel, the German physicist Julius Plücker, the Swiss chemist Christian Schoenbein, the natural philosopher William Thomson and the Cambridge philosopher William Whewell.

The Correspondence will be a valuable resource for historians and sociologists of science and technology, as well as historians of the nineteenth century and the industrial revolution. It will also be of great interest to electrical engineers, physicists and chemists who want to know more about one of the most eminent figures in their history.

Spectral Theory and Excitation of Open Structures

Mon, 11 Jun 2018 22:56:16 GMT

Open resonators, open waveguides and open diffraction gratings are used extensively in modern millimetre and submillimetre technology, spectroscopy and radio engineering. The physical principles of open electrodynamic structures are different from those of closed ones because of radiation loss, edges, multiconnected cross-sections and the need to take into account the behaviour of electromagnetic fields at infinity. The eigenoscillation and eigenwave spectra become complex, there are additional demands on the energy relations and the statements of spectral problems change.

In this book the physical processes in open electrodynamic structures are analysed using a specially constructed spectral theory. The basic concept is that physical processes are observed at real frequencies, and continuation to the complex domain is considered as a mathematical method. The data obtained at complex frequencies give essential information about 'real' solutions at real frequencies. The approach developed allows not only the egular but a variety of anomalous dispersion laws and effects to be investigated.

Written by two authorities in the field of mathematical modelling, the book should be of interest to all scientists and engineers concerned with modern methods of analytical solution of electromagnetic problems in open domains, as well as those studying theoretical electromagnetics.

Advanced Robotics and Intelligent Machines

Mon, 11 Jun 2018 21:07:31 GMT

The term 'advanced robotics' came in the 1980s to describe the application of advanced sensors and new developments in cognitive science and artificial intelligence to the traditional robot. Today, advanced robots have come far beyond the limitations of the crude 'pick-and-place' machines of the 1980s assembly line, and have a vast range of applications in manufacturing, construction and health care, as well as hostile environments such as space, underwater and nuclear applications.

This book provides an essential overview of developments in the basic technologies, looking at recent applications and highlighting a number of advanced concepts and procedures that may influence future developments. The emphasis is on developments in Europe, although the book is also relevant to activities in the USA, Japan and elsewhere. With such a wide and dynamic field, it does not attempt to provide a comprehensive guide; rather, it addresses many key elements of the technology to furnish a complete introduction for both postgraduate students and practising engineers attracted to the challenges of the domain.
