Delusions of electronic persecution have been a preeminent symptom of psychosis for over two hundred years. In The Technical Delusion Jeffrey Sconce traces the history and continuing proliferation of this phenomenon from its origins in Enlightenment anatomy to our era of global interconnectivity. While psychiatrists have typically dismissed such delusions of electronic control as arbitrary or as mere reflections of modern life, Sconce demonstrates a more complex and interdependent history of electronics, power, and insanity. Drawing on a wide array of psychological case studies, literature, court cases, and popular media, Sconce analyzes the material and social processes that have shaped historical delusions of electronic contamination, implantation, telepathy, surveillance, and immersion. From the age of telegraphy to contemporary digitality, the media emerged within such delusions to become the privileged site for imagining the merger of electronic and political power, serving as a paranoid conduit between the body and the body politic. Looking to the future, Sconce argues that this symptom will become increasingly difficult to isolate, especially as remote and often secretive powers work to further integrate bodies, electronics, and information.
Technology Computer Aided Design for Si, SiGe and GaAs Integrated Circuits is the first book that deals with a broad spectrum of process and device design, and modelling issues related to various semiconductor devices. This monograph attempts to bridge the gap between device modelling and process design using TCAD. Many simulation examples for different types of Si-, SiGe-, GaAs- and InP-based heterostructure MOS and bipolar transistors are given and compared with experimental data from state-of-the-art devices. Bringing various aspects of silicon heterostructures into one resource, this book also presents a comprehensive perspective of the emerging field and covers topics ranging from materials to fabrication, devices, modelling and applications.
The monograph is aimed at research and development engineers and scientists who are actively involved in microelectronics technology and device design via Technology CAD. It will also serve as a reference for postgraduate and research students in the field of electrical engineering and solid-state physics, and for TCAD engineers and developers.
The temperature on earth varies over a wide range whereas man can only work comfortably in a quite narrow temperature range that has to be artificially maintained. In addition, many industries have extensive requirements for temperature control. Thus control engineers are called upon very frequently to design temperature control loops.
A general knowledge of control engineering is of course useful in designing temperature control loops.However, temperature control has some special features:
(i) asymmetries caused by the usually differing mechanisms of heating and cooling
The intention of this book is to treat the theory and practice of temperature measurement and control, and important related topics such as energy management and air pollution, at a level suitable for engineering and science undergraduate and postgraduate students, and in a manner designed to make the book valuable to practising engineers. There are no specific prerequisites for the book although a knowledge of elementary control theory could be useful.
The philosophy of the book is a compromise between fundamentals and practical guidelines. It is the author's firm belief that it is highly desirable to obtain a good insight into theoretical fundamentals (deeper than can be justified on grounds of immediate utility) before embarking on practical applications. The aim has been to produce a practically oriented text within a firm theoretical outline.
The first half of the book is an application oriented survey of temperature measurement techniques and devices. The second half is concerned mainly with temperature control in both simple and complex situations. There are chapters on heat sources, commercially available controllers, temperature control in buildings and energy conservation. The book ends with an appendix that rapidly surveys the underpinning thermodynamic theory.
Systems on Chip (SoC) for communications, multimedia and computer applications have recently received much international attention; one such example being the single-chip transceiver. Modern microelectronic design adopts a mixed-signal approach as a complex SoC is a mixed-signal system including both analogue and digital circuits. Automatic testing becomes crucially important to drive down the overall cost of next generation SoC devices. Test and fault diagnosis of analogue, mixed-signal and RF circuits, however, proves much more difficult than that of digital circuits due to tolerances, parasitics and nonlinearities and therefore, together with challenging tuning and calibration, remains the bottleneck for automatic SoC testing. This book provides a comprehensive discussion of automatic testing, diagnosis and tuning of analogue, mixed-signal and RF integrated circuits, and systems in a single source. The book contains eleven chapters written by leading researchers worldwide. As well as fundamental concepts and techniques, the book reports systematically the state of the arts and future research directions of these areas. A complete range of circuit components are covered and test issues are also addressed from the SoC perspective. An essential reference companion to researchers and engineers in mixed-signal testing, the book can also be used as a text for postgraduate and senior undergraduate students.
This unique book serves as both text and practical reference for all personnel involved in avionics and weapons system evaluation and testing, in the air and on the ground. Whether you are training pilots and personnel or actually planning to test systems, this book will provide you with the fundamentals and practical information you need to get the job done. The book is a compilation of experiences and methods from over 25 years in the business and interaction with Test Pilots and Test Engineers over the last 15 years as an Instructor/Director at the National Test Pilot School in Mojave, California. The book was also reviewed by a dozen voluntary experts from the military and industry to ensure all critical components are covered properly. Their comments and suggestions were integrated into the text toward the goal of creating this invaluable textbook and companion to the fighter or heavy aircraft test team, no matter their geographical location. Lessons learned, good and bad, are addressed in each chapter so readers can avoid the pitfalls common to test and evaluation of these systems. Exercises at the end of each chapter provide instructors with the ability to reinforce critical concepts and all the war stories in the book are true.
Microwave filters are vital components in a huge variety of electronic systems, including the rapidly growing communications industry behind mobile radio and satellite communications, as well as radar and other microwave technologies. Ian Hunter provides a graduate-level text that has the aim of enabling the engineer to understand the theory and design of microwave filters.
This book is extremely thorough and covers fundamental circuit theory and electromagnetics, network synthesis, applications and the design of a variety of real microwave structures, all in a single source. The philosophy is to present design theories followed by specific examples with numerical simulations of the designs, accompanied by pictures of real devices wherever possible.
The intended primary readership is professional engineers in the communications and microwave industries, where the book will be suitable for recent graduates working with and designing filters for the first time, through to engineering managers responsible for RF system design. MSc students in microwave and RF engineering will find the book highly relevant, as the author has developed much of the material from his graduate-level courses for university and industry. Theory and Design of Microwave Filters will also be a valuable reference work in the research community.
This book provides a comprehensive introduction and explanation of both the theory and practice of all forms of modern antenna measurements, from their most basic postulates and assumptions to the intricate details of their application in various demanding modern measurement scenarios.
Theory and Practice of Modern Antenna Range Measurements begins with an initial examination of the properties of antennas that allow them to enhance the free space interaction of electronic systems, followed by an introduction to direct far-field measurements. The text presents a comprehensive treatment of Compact Antenna Test Ranges, Body-Centric measurements, and detailed developments of standard planar, cylindrical and spherical near-field techniques. Detailed discussions are also provided on near-field range error budgets which are an indispensable part of antenna metrology. The book concludes with some of the most recent advances in the various measurement techniques including aperture diagnostics, phase-less antenna metrology, error correction, range multi-path suppression techniques, and gain measurements. Extensive examples illustrate the concepts and techniques.
A large number of antenna test facilities exist worldwide but to the authors' knowledge no single text provides a clear step-by-step description of all the details of the Planar, Cylindrical, Spherical Near-Field, Compact Range and Body-centric Measurement Techniques. All four authors have spent a significant proportion of their professional careers involved with antenna measurements and the aim of this text is to provide the reader with a complete, coherent, comprehensive and practical text that will act as a single reference for all aspects of modern antenna measurements.
This book is an essential resource for researchers involved in designing antennas and RCS calculations. It is also useful for students studying high frequency diffraction techniques. It contains basic original ideas of the Physical Theory of Diffraction (PTD), examples of its practical application, and its validation by the mathematical theory of diffraction. The derived analytic expressions are convenient for numerical calculations and clearly illustrate the physical structure of the scattered field. The text's key topics include: Theory of diffraction at black bodies introduces the Shadow Radiation, a fundamental component of the scattered field; RCS of finite bodies of revolution-cones, paraboloids, etc.; models of construction elements for aircraft and missiles; scheme for measurement of that part of a scattered field which is radiated by the diffraction (so-called nonuniform) currents induced on scattering objects; development of the parabolic equation method for investigation of edge-diffraction; and a new exact and asymptotic solutions in the strip diffraction problems, including scattering at an open resonator.
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.
This book combines theoretical concepts with experimental results on thermal microwave radiation to advance the understanding of the complex nature of terrestrial media. With the emphasis on radiative transfer models the book covers the most urgent needs for the transition from the experimental phase of microwave remote sensing to operational applications. All terrestrial aspects are covered from the clear to the cloudy atmosphere, precipitation, ocean and land surfaces, vegetation, snow and ice.
A chapter on new results of microwave dielectric properties of natural media, covering wavelengths from the decimetre to the submillimetre range, will be a source for further radiative transfer developments, extending the applicability to radar and other electromagnetic tools, and including extraterrestrial objects, such as planets and comets.
The book resulted from a continued collaboration set up by the European COST Action No. 712 Application of Microwave Radiometry to Atmospheric Research and Monitoring (1996-2000). The aims of the action were to improve the application of microwave radiometry with emphasis on meteorology.
This book provides a complete discussion of the Gauss-Newton filters, including all necessary theoretical background. This book also covers the expanding and fading memory polynomial filters based on the Legendre and Laguerre orthogonal polynomials, and how these can serve as pre-filters for Gauss-Newton. Of particular interest is a new approach to the tracking of manoeuvring targets that the Gauss-Newton filters make possible. Fourteen carefully constructed computer programs demonstrate the use and power of Gauss-Newton and the polynomial filters. Two of these also include Kalman and Swerling filters in addition to Gauss-Newton, all three of which process identical data that have been pre-filtered by polynomial filters. These two programs demonstrate Kalman and Swerling instability, to which Gauss-Newton is immune, and also the fact that if an attempt is made to forestall Kalman/Swerling instability by the use of a Q matrix, then they cease to be Cramér-Rao consistent and become less accurate than the always Cramér-Rao consistent Gauss-Newton filters.
