Spread Spectrum in Mobile Communication

Tue, 12 Jun 2018 01:33:00 GMT

Mobile communication is one of the most important applications in the tele-communications and IT field. Developments in technology are enabling the design of advanced mobile radio networks linking information processing and data routing, with the radio segment sandwiched between layers of digital signal processors. Spread spectrum technology adapts radio communication to computational data information processing networks.

This book presents the concepts of modern mobile communication and discusses the user requirements and operational environment which influence mobile systems design. Its focus is on the mobility issues for a decentralised network topology and the effects of spread spectrum modulation on radios used in packet-switched networks. Connecting radio terminals using packet switching gives a highly flexible and efficient solution for mobile users, and the book gives considerable space to discussing packet switching in radio networks, protocols and routing strategies. Providing vital information for all those in the mobile systems field, the book is supported by detailed case study information to illustrate the practical issues involved in implementing the technology.

VLSI Testing

Tue, 12 Jun 2018 01:06:58 GMT

The importance of testing integrated circuits (ICs) has escalated with the increasing complexity of circuits fabricated on a single IC chip. No longer is it possible to design a new IC and then think about testing: such considerations must be part of the initial design activity, and testing strategies should be part of every circuit and system designer's education. This book is a comprehensive introduction and reference for all aspects of IC testing. It includes all of the basic concepts and theories necessary for advanced students, from practical test strategies and industrial practice, to the economic and managerial aspects of testing. In addition to detailed coverage of digital network testing, VLSI testing also considers in depth the growing area of testing analogue and mixed analogue/digital ICs, used particularly in signal processing.

Television

Tue, 12 Jun 2018 00:38:00 GMT

From the first notions of 'seeing by electricity' in 1878, through the period of the first demonstration of rudimentary television in 1926 and up to 1940, when war brought the advance of the technology to a temporary halt, the development of television gathered about it a tremendous history. Following the discovery of the photo-conductive effect, numerous schemes for television were suggested but it was in the wake of Baird's early demonstrations that real industrial interest developed and the pace of progress increased. Much research and development work was undertaken in the UK, the US, Germany and France. By 1936 television technology had advanced to the point where high definition broadcasting was realistic.

This meticulous and deeply researched book presents a balanced and thorough international history of television from 1878 to 1940, considering the factors - technical, commercial and social - that influenced and led to the establishment of public services in many countries. Highly illustrated throughout, this is a major book in the study of history of science, technology and media.

Small Electric Motors

Mon, 11 Jun 2018 23:56:48 GMT

Users of small electric motors face the difficult task of selecting the best motor for their particular drive application. The technical requirements of the drive, the level of safety needed and the cost factor must all be considered. The choice is made more difficult by the continuous arrival of newly developed types of motor. This book, a translation from German, aims to help those involved in specifying, developing, manufacturing and marketing small motors by reporting the current state of the art.

The various types of motor, together with their differing characteristics and their relationship to small drives are covered. Developments such as brushless DC motors and stepper motors are discussed, as well as the use of electronic control which widens the spectrum of small motor applications. Also covered are measurement and noise problems.

This book will be of interest to engineers, physicists and technicians involved in the design, manufacture and application of small motors in the laboratory, the factory and in service.

Since the first edition of this book in 1983, HVDC technology has continued to expand and few power systems can now escape its influence. This thoroughly revised text develops the coverage in the first edition, describing the variety of reasons justifying the use of DC transmission as well as the basic concepts and techniques involved in the AC-DC and DC-AC conversion processes. It has been fully updated and enlarged to include descriptions of the widening applications of DC, the current state-of-the-art thyristors and other semiconductor devices, and the new developments that continue to make HVDC a competitive technology.

The book should be of interest to practising engineers and researchers involved in the power industry. It will also be of assistance to lecturers and students in the power systems and power electronics disciplines.

Engineers' Handbook of Industrial Microwave Heating

Mon, 11 Jun 2018 23:27:30 GMT

Heating materials using microwave energy offers many advantages in industrial processes, including improved quality, efficiency and control. There is a growing interest in microwave heating throughout industry and there are now many research establishments, both academic and industrial, working in this field. Microwave technology is a well developed science in the areas of radar and communications, supported by a large bibliography, but this is not the case for its applications to industry. The aim of this book is first to present the fundamentals of microwave technology that are relevant to industrial practice in a manner accessible to engineers, scientists and technicians who may have little or no prior knowledge of the subject. Second, it presents a perspective on the range and scope of the techniques and hardware used, giving detailed descriptions, making critical comparisons and commenting frequently on practical issues of design.

AC-DC Power System Analysis

Mon, 11 Jun 2018 23:08:38 GMT

With the expansion of HV DC transmission throughout the world, and the increasing numbers of international interconnections, few power systems can continue to escape the effect of this technology in their planning and operation. The primary subject of this book is the incorporation of AC-DC converters and DC transmission in power system analysis. However, the concepts and methods described are also applicable to the FACTS (flexible AC transmission systems) technology.

As well as conventional power flows, faults and stability, the book describes the simulation of power system steady-state waveform distortion and transient behaviour. The modelling of power electronic devices in electromagnetic transient programs is given prominence, as these programs have become the 'workhorse' of power system design.

This graduate-level text should be of interest to practising engineers and researchers involved in the solution of modern power system problems. It will also be a useful reference for advanced electrical engine ering students.

Theory of Nonuniform Waveguides

Mon, 11 Jun 2018 23:02:08 GMT

The cross-section method is an analytical tool used in the design of components required for low-loss, highly efficient transmission of electromagnetic waves in nonuniform waveguides. When the waveguide dimensions are large compared with the wavelength, a fully three-dimensional analysis employing modern numerical methods based on finite element, finite difference, finite integration or transmission line matrix formalisms is practically impossible and the cross-section method is the only feasible analysis technique.

The method is not limited to oversized tubular metallic waveguides, but is employed intensively in areas such as fibre optic communications, antenna synthesis, natural waveguides (submarine, tropospheric and seismic), microwave radio links (Earth or space) and the design of absorbing surfaces and it may also be applied to many acoustic problems. The application of the method in special cases such as cut-off and resonant frequencies is covered, as well as the design of oversized waveguide components such as tapers, bends, polarisers and mode converters. Many useful formulas are given for the practical layout of such transmission line components. The use of computers in the application of the method and problems related to numerical analysis are also covered.

Introduction to Airborne Radar, 2nd Edition

Mon, 11 Jun 2018 22:26:01 GMT

Introduction to Airborne Radar is the revision of the classic book privately published by Hughes Aircraft Company in 1983. Lavishly produced in full color, the book was quite unlike any commercially published radar book produced by the major technical publishers. The combination of clear, understandable writing and the unparalleled illustrations established the text-reference as a 'must-have' for engineers, technicians, pilots, and even sales and marketing people within the radar and aerospace industry. The book was authored by veteran Hughes engineer and Technical Manager George W. Stimson, a publications specialist. Individual chapters were thoroughly reviewed by the appropriate experts within the Hughes Radar Systems Group. The book was initially available 1983-1987 only to those within the Hughes family: employees and customers, primarily the military. Restriction was lifted in 1987. Hughes went through three printings and 40,000 copies 1983-1993, mostly by word-of-mouth testimonials and demand. Upon retirement from Hughes, George Stimson successfully negotiated for the rights to the book and made an agreement with SciTech Publishing to do a major revision of the text to update it. The resulting Second Edition has been overwhelmingly positive and a best-seller. Second Edition The revision is extensive: thirteen entirely new chapters cover the technological advances over the fifteen years since publication, two chapters considered obsolete have been deleted entirely, three chapters are extensively rewritten and updated, two chapters have been given new sections, and fourteen chapters have been given minor tweaks, corrections, and polishing. The book has grown from 32 chapters to 44 chapters in 584 efficiently-designed pages. Efforts have been made to bring more even-handed coverage to radars developed outside of Hughes Aircraft, while older and less important Hughes radars have been deleted or abbreviated. Chapter 44 catalogs many of the cutting edge radars in functioning aircraft and near-service aircraft in early stages of production. The book's appeal is to a diverse audience: from military pilots and radar officers eager to gain a sound technical understanding of the complex systems that their lives depend upon, on up through technicians, marketing, and sales people, to the radar system design specialists, who may 'know all that stuff' but who deeply admire the expression and thus use the book to teach others who have questions. The market encompasses companies directly involved in the radar business and those on the periphery, college professors of engineering and physics themselves, along with students in aviation, aeronautics, and electromagnetics and radar courses. The cross-disciplinary and multi-level demand for the book shows that the book should not be pigeon-holed as just a radar book for electrical engineers. Virtually anybody with a knowledge of high school algebra, trigonometry, and physics will be able to read and absorb most of the material.

Mon, 11 Jun 2018 21:33:27 GMT

IEC 1131-3 is the international standard for the design of software for industrial control systems. It defines a set of related graphical and textual languages that bring significant benefits throughout the control system life-cycle - benefits for system integrators, control system engineers and end-users alike. The standard marks the beginning for wellstructured, re-usable and maintainable software for industrial control systems.

This new edition has been revised and updated to include all IEC proposed amendments and corrections for the planned 1999 edition of IEC 1131-3, agreed by the IEC working group in spring 1998. The book now includes IEC 1131-3 'frequently asked questions' and a summary of future developments influencing the next generation of PLC languages, plus an overview of IEC 1499 standard on function blocks.

Although primarily for programmable logic controllers (PLCs), IEC 1131-3 concepts will also influence the design of software for fieldbus devices.

This book introduces all the concepts of the IEC 1131-3 standard and provides examples of the languages related typical industrial control problems. It will be of interest to everyone involved in specifying or developing software for industrial or manufacturing applications. The text will also be of value to students and engineers with a general interest in new techniques for industrial or manufacturing applications.
