Electromagnetic interference or compatibility is a challenge faced by circuit designers across all areas of research, applications and industries, and is the subject of strict regulatory requirements. Darney's Circuit Modelling for Electromagnetic Compatibility, 2nd Edition shows how the analytical tools of circuit theory can be used to simulate the coupling of interference into, and out of, any signal link in the system being reviewed. This approach offers EMC testers and product designers a tool to work with at an early stage, before running expensive Faraday cage tests, which offers insight into whether a design is on the right track to achieving its design specification and so saving time and money.

The equipotential earth is a fundamental requirement of circuit theory, because it dramatically reduces the complexity of the mathematics required to simulate a circuit. Unfortunately, in the real world, no such equipotential earth exists, nor can it ever do so, which means simulating a circuit to evaluate its electromagnetic compatibility (EMC) and susceptibility to electromagnetic interference (EMI) is largely dependent on using the Maxwell equations. The Maxwell equations are inherently complex, however, and so have high processing power requirements and, as with all complex systems, there is a propensity to generate and magnify errors.

The scientific research in many engineering fields has been shifting from traditional first-principle-based to data-driven or evidence-based theories. The latter methods may enable better system design, based on more accurate and verifiable information.

The unavoidable element in the development of flight control systems (to date) has been in hydraulic actuators. This has been the case primarily because of their proven reliability and the lack of alternative technologies. However, the technology to build electromechanically actuated primary flight control systems is now available, which may mark the end of the hydraulic actuation systems - an important step for the development of the future 'all-electric' aircraft.

Robust control theory allows for changes in a system whilst maintaining stability and performance. Applications of this technique are very important for dependable embedded systems, making technologies such as drones and other autonomous systems with sophisticated embedded controllers and systems relatively common-place.

Analogue filters will always be needed for interfacing between digital systems and the 'real' analogue world. In fact, the high frequency integrated analogue filter has become a key component in achieving ubiquitous communication and computing. In recent years, the renewed interest in analogue, mixed-signal and RF circuits due to the need for system-on-chip design and the market for wireless communications has led to a new peak of research into high frequency integrated analogue filters.

This book presents developments in analysis and design techniques for control systems. Included are exciting results for feedback systems using complex variable methods, the important concept of robustness in controller design and the increasingly important topic of decentralized control for large scale systems. These and many other contributions illustrate the great activity and rapid progress which has taken place in the subject over the past few years. Only by bringing these contributions together under one cover can the practising engineer in industry and indeed the engineer in university or polytechnic keep fully informed on the 'state of the art' on a number of different fronts. Application of the theoretical developments and practical aspects of the subject are not forgotten; analysis and design of a nuclear boiler and some direct digital control system design procedures are but two topics discussed in the present book. Several of the chapters are followed by problems on the subject matter and worked solutions to most of these problems are given at the end of the book. This aspect will find favour with many readers since such contributions are often a great help in the understanding of the subject matter.

Communications technology at a frequency range into Terahertz (THz) levels has attracted attention because it promises near-fibre-optic-speed wireless links for the 5G and post-5G world. Transmitter and receiver integrated circuits based on CMOS, which has the ability to realize such circuits with low power consumption at a low cost, are expected to become increasingly widespread, with much research into the underlying electronics currently underway.

This handbook outlines the factors that must be considered in designing circuits, equipment, and systems for electromagnetic compatibility (EMC). It teaches circuit and system designers practical approaches to thwart the ever present culprit of electromagnetic interference (EMI). By emphasizing the fundamentals, it provides information that will help readers understand the rationale that forms the basis for many of the EMC practices and procedures. There is much information about these topics available in disparate forms (journal articles, symposia proceedings, etc.) but this book brings the critical knowledge into a single source for battling EMI.

One of the main fields of study in the control of dynamical systems has been the effective control of time-varying systems with uncertain parameters and external disturbances. In contrast to stochastic adaptive controllers with identification algorithms, the deterministic control of uncertain time-varying systems has a fixed nonlinear feedback controller, which operates effectively over a specified magnitude range of a class of system variations. If the variations satisfy certain matching conditions, complete insensitivity to system uncertainties can be achieved. The two main approaches are Variables Structure and Lyapunov control. The contents of this book reflect the research output of many authors. The chapters include material of an introductory nature as well as some of the latest research results. Attention has also been focussed upon some of the main areas of application, which include electric motor drives, robotics and flight control systems. The book should prove useful to control designers, theoreticians and graduate students.

Glocal control, a term coined by Professor Shinji Hara at The University of Tokyo, represents a new framework for studying behaviour of complex dynamical systems from a feedback control perspective. A large number of dynamical components can be interconnected and interact with each other to form an integrated system with certain functionalities. Such complex systems are found in nature and have been created by man, including gene regulatory networks, neuronal circuits for memory, decision making, and motor control, bird flocking, global climate dynamics, central processing units for computers, electrical power grids, the World Wide Web, and financial markets. A common feature of these systems is that a global property or function emerges as a result of local, distributed, dynamical interactions of components. The objective of 'glocal' (global + local) control is to understand the mechanisms underlying this feature, analyze existing complex systems, and to design and create innovative systems with new functionalities. This book is dedicated to Professor Shinji Hara on the occasion of his 60th birthday, collecting the latest results by leading experts in control theories to lay a solid foundation towards the establishment of glocal control theory in the coming decades.

Uncovers the diverse and unexpected ways aging populations engage with technology.

As digital technologies further embed themselves in everyday life, how do older adults navigate and adapt to these tools? Digital Repertoires introduces the concept of the “digital repertoire” to investigate the evolving ways older people engage with technology across cultural and social contexts. Based on global research, this work confronts typical stereotypes of aging and digital exclusion and emphasizes the agency, creativity, and new challenges older adults experience in their digital interactions.

Including voices of scholars from anthropology, sociology, gerontology, communication studies, and design, this book offers theoretical depth as well as empirical breadth, making it essential reading for researchers, practitioners, and policymakers working at the intersection of aging and technology.
 

This is a study of the material life of information and its devices; of electronic waste in its physical and electronic incarnations; a cultural and material mapping of the spaces where electronics in the form of both hardware and information accumulate, break down, or are stowed away. Electronic waste occurs not just in the form of discarded computers but also as a scatter of information devices, software, and systems that are rendered obsolete and fail. Where other studies have addressed "digital" technology through a focus on its immateriality or virtual qualities, Gabrys traces the material, spatial, cultural, and political infrastructures that enable the emergence and dissolution of these technologies. In the course of her book, she explores five interrelated "spaces" where electronics fall apart: from Silicon Valley to Nasdaq, from containers bound for China to museums and archives that preserve obsolete electronics as cultural artifacts, to the landfill as material repository. All together, these sites stack up into a sedimentary record that forms the "natural history" of this study.

Digital Rubbish: A Natural History of Electronics describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. By drawing on the material analysis developed by Walter Benjamin, this natural history method allows for an inquiry into electronics that focuses neither on technological progression nor on great inventors but rather considers the ways in which electronic technologies fail and decay. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys pulls together the far-reaching material and cultural processes that enable the making and breaking of these technologies.

Jennifer Gabrys is Senior Lecturer in Design and Convener of the Masters in Design and Environment in the Department of Design, Goldsmiths, University of London.

Recent progress in the design and production of digital signal processing (DSP) devices has provided significant new opportunities to workers in the already extensive field of signal processing. It is now possible to contemplate the use of DSP techniques in cost-sensitive wide bandwidth applications, thereby making more effective use of the large body of available signal processing knowledge. Digital signal processing, long the province of telecommunications is, in both research and applications contexts, of growing importance in fields of medical signal analysis, industrial control (particularly robotics), in the analysis and synthesis of speech and in both audio and video entertainment systems. The growing demand for engineering skills in these areas has led to the writing of this book and the presentation of the material of the book at an lEE-sponsored Vacation School at the University of Leicester.

One of the most far-reaching transformations in our era is the wave of digital technologies rolling over—and upending—nearly every aspect of life. Work and leisure, family and friendship, community and citizenship have all been modified by now-ubiquitous digital tools and platforms. Digital Technology and Democratic Theory looks closely at one significant facet of our rapidly evolving digital lives: how technology is radically changing our lives as citizens and participants in democratic governments.
To understand these transformations, this book brings together contributions by scholars from multiple disciplines to wrestle with the question of how digital technologies shape, reshape, and affect fundamental questions about democracy and democratic theory. As expectations have whiplashed—from Twitter optimism in the wake of the Arab Spring to Facebook pessimism in the wake of the 2016 US election—the time is ripe for a more sober and long-term assessment. How should we take stock of digital technologies and their promise and peril for reshaping democratic societies and institutions? To answer, this volume broaches the most pressing technological changes and issues facing democracy as a philosophy and an institution.
 

To obtain the full value from instrumentation, users require familiarity with a number of basic concepts and an understanding of how those building blocks relate to one another. In this book, Nihal Kularatna provides an introduction to the main families of instruments for students and professionals who have to carry out practical work in electronics and measurement. For each family he covers internal design, use and applications, highlighting their advantages and limitations from a practical application viewpoint.

Digitally enhanced analog and mixed signal techniques are increasingly important to current and future circuit and system design. This book discusses how digital enhancement can be used to address key challenges relevant to analog components in terms of shrinking CMOS technology, increasing user demand for higher flexibility and data traffic in communications networks, and the drive to reduce power consumption.

In recent years technological advancements in the design and fabrication of integrated circuits have led to the development of cost effective, low power, thumb-size devices that can be used for sensing/actuating, communication and computing. This trend is enabling a surge of new applications for which pervasive network architectures are being developed. A key feature of these systems is that they are decentralized and communication among different subsystems may be unreliable. From an engineering viewpoint, to ensure correct operation, the theoretical analysis requires a fundamental paradigm shift, as many of the typical assumptions of systems and control theory cease to hold.

Distributed feedback (DFB) semiconductor lasers emit light in a single mode which is essential to providing the carrier in long haul high bit-rate optical communication systems. This comprehensive research monograph provides:

Driver information and assistance systems have emerged as an integral part of modern road vehicles in order to support the driver while driving. They make use of the newest information technologies in order to enhance driver awareness, safety and comfort, and thereby avoiding driver errors and accidents. Driver Adaptation to Information and Assistance Systems brings together recent work by the Marie-Curie Initial Training Network ADAPTATION. The project has studied drivers' behavioural adaptation to these new technologies from an integrative perspective working under a joint conceptual theoretical framework of behavioural adaptation that can be used to generate research hypotheses about how drivers will adapt to information and assistance systems and to derive guidelines for the design and deployment of such systems.
