As biometrics-based identification and identity authentication become increasingly widespread in their deployment, it becomes correspondingly important to consider more carefully issues relating to reliability, usability and inclusion. One factor which is particularly important in this context is that of the relationship between the nature of the measurements extracted from a particular biometric modality and the age of the sample donor, and the effect which age has on physiological and behavioural characteristics invoked in a biometric transaction.

Induction motors are still among the most reliable and important electrical machines. The wide range of their use involves various electrical, magnetic, thermal and mechanical stresses which results in the need for fault diagnosis as part of the maintenance. A yet unreached goal is the development of a generalized, practical approach enabling industry to accurately diagnose different potential induction motor faults.

The need to measure electrical power is common to many branches of science and engineering. This book presents a wide-ranging survey of the many types of radio-frequency and microwave power meter and the techniques which are used for calibrating and intercomparing them. The frequency range is 1 MHz to 200 GHz.

This book is devoted to the description of optimum signal processing algorithms which can find useful applications in radar systems. The monograph collects about twenty papers written by the Editor and his colleagues. Structurally the collection of the papers is divided into four parts. The first describes the adaptive cancellation techniques of radar clutter; the second part addresses the challenging problem of finding the optimum detection schemes to deal with target and clutter signals having non-Gaussian probability density function, and any type of autocorrelation function. The third group of papers considers the problem of finding the optimum detection schemes for the case of netted multi-static radar systems. The last part is concerned with more general processing techniques used in radar systems for surveillance.

Cognitive dynamic systems are inspired by the computational capability of the brain and the viewpoint that cognition is a supreme form of computation. The key idea behind this new paradigm is to mimic the human brain as well as that of other mammals with echolocation capabilities which continuously learn and react to stimulations according to four basic processes: perception-action cycle, memory, attention, and intelligence.

This book has been written with the intention of helping those who ore concerned with planning, ordering, managing and using telecommunications facilities in connection with their business activities, and who do not wish to obtain a detailed technical and mathematical knowledge of the subject. The various types of telecommunications traffic are analysed without recourse to the underlying theory, and the reader is introduced to the terminology and operation of modern telecommunications systems and networks. Particular attention is paid to the relationship between traffic-carrying capacity and cost, and to the importance of traffic measurement and forecasting as a means of matching equipment provision to demand. The role of performance targets is discussed and the book explains how a comparison between public-network tariff options and the cost of private system and network alternatives can ensure a cost-effective solution to any communications problem. The principles are demonstrated by simple worked examples and a detailed glossary of terms is included.

The control of the longitudinal, lateral and vertical dynamics of two and four-wheeled vehicles, both of conventional type as well as fully-electric, is important not only for general safety of vehicular traffic in general, but also for future automated driving.

This book presents the basic principles of transistor circuit analysis, basic per-stage building blocks, and feedback. The content is restricted to quasi-static (low-frequency) considerations, to emphasize basic topological principles. The reader will be able to analyze and design multi-stage amplifiers with feedback, including calculation and specification of gain, input and output resistances, including the effects of transistor output resistance. Of note is the presentation of feedback analysis, a subject rarely covered by other books, with insights and from angles that will reduce to analysis by inspection for readers. Some circuit transformations outlined within are especially helpful in reducing circuits to simpler forms for analysis. They are usefully applied in considering transistor circuits for which collector-emitter (or drain-source) resistance is not negligible, another often omitted topic which this book details.

This second volume, Analog Circuit Design: Designing Dynamic Circuit Response, builds upon the first volume (Analog Circuit Design: Designing Amplifier Circuits) by extending coverage to include reactances and their time- and frequency-related behavioral consequences. Retaining a design-oriented analysis, this volume begins with circuit fundamentals involving capacitance and inductance and lays down the approach using s-domain analysis. Additional concepts and perspectives fill in the blanks left by textbooks in regards to circuit design. It simplifies dynamic circuit analysis by using the graphical methods of reactance plots. Methods of compensating amplifiers, including feedback amplifiers, are kept as simple as possible using reactance plots and s-domain transfer functions that mainly require algebraic skill.

The third volume, Analog Circuit Design: Designing High-Performance Amplifiers, applies the concepts from the first two volumes. It is an advanced treatment of amplifier design/analysis emphasizing both wideband and precision amplification. Topics include bandwidth extension, noise and distortion, effects of components, instrumentation and isolation, amplifiers, autocalibration, thermal effects, current-feedback amplifiers, multi-path schemes, feed forward, f_T multipliers, buffers, voltage translators, Giulbert gain cells and multipliers.

The fourth volume in the set, Analog Circuit Design: Designing Waveform-Processing Circuits, builds on the previous 3 volumes and presents a variety of analog non-amplifier circuits, including voltage references, current sources, filters, hysteresis switches and oscilloscope trigger and sweep circuitry, function generation, absolute-value circuits, and peak detectors. Digitizing (ADCs and DACs) and sampling (including some switched-capacitor) circuits are explained, with theory required for design. Sampling theory is developed from both a frequency and time-domain viewpoint, with emphasis upon application to design.

This book is intended to explain the technical principles involved in the many AC variable speed drive systems available today. It deals with all the DC link inverter and direct AC to AC converter systems that are in commercial use. The principles of AC motors are considered specifically from the variable frequency point of view, and this chapter concentrates on the effects of harmonics. The different types of power semiconductor switches are considered separately from the drive systems in which they are used.

If there are two phrases we have come to know very well, they are 'environmental awareness' and 'credit crunch'. The world is looking for ways to decrease the emission of CO₂ into the atmosphere, without incurring major costs in doing so. By increasing efficiencies up to about 90 per cent using well-established and mature technologies, cogeneration represents the best option for short-term reductions in CO₂ emission levels.

Telecommunications is vital to modern life, and the global telecommunication network that has developed is an essential part of the infrastructure of society. Although there is an extensive literature on many aspects of telecommunication technology, comparatively little has been published on the functioning and planning of complete telecommunication networks. The first edition of this book was intended to help fill that gap and this new edition has been thoroughly revised and includes much new material.

Active and Assisted Living (AAL) systems aim at improving the quality of life and supporting independent and healthy living of older or impaired people by using a distributed network of sensors and actuators to create a ubiquitous technological layer, able to interact transparently with the users, observing and interpreting their actions and intentions, learning their preferences and adjusting the parameters of the system to improve their quality of life and work. This book provides a comprehensive review of the technologies and applications for AAL.

The aim has been to provide an up-to-date analysis of the theoretical and practical problems involved in circuit breaker design. Circuit breakers present very special design problems because of the wide mixture of experience required.

Significant changes over the past decade in computing technology, along with widespread deregulation of electricity industries, have impacted on power plant operations while affording engineers the opportunity to introduce monitoring and plant-wide control schemes that were previously unfeasible. Contributors of world-class excellence are brought together in Thermal Power Plant Simulation and Control to illustrate how current areas of research can be applied to power plant operation, leading to enhanced unit performance, asset management and plant competitiveness through intelligent monitoring and control strategies.

Marketing is a big topic. It is complex, vital - and yet too often misunderstood.

An opportunity to impress, Communication is easy isn't it? Well it may seem so, but consider honestly when was the last time you were involved in a breakdown of communications? And how long ago was one such a veritable derailment? For most people and in most organisations this happens regularly.

The rapid growth of wind generation has many implications for power system planning, operation and control. Network development, voltage rise, protection, monitoring and control are connection problems common to all wind power generation.

The rapid growth of wind generation has many implications for power system planning, operation and control. This would have been a considerable challenge for the old nationalised power companies; it has become an even greater challenge in today's liberalised electricity markets.

The business of telecommunications is undergoing a period of change driven by changes in regulation, increasing demands for services and the development of new access technologies. The market structure of telecommunications is evolving rapidly as new and existing players strive to compete in an increasingly volatile market, while the advent of new data services is placing greater demands on the network as operators strive to offer new broadband services. Underpinning much of this change is the access technology itself, not only in the transitional form of copper twisted pairs, but also increasingly through the use of new fibre, radio and copper systems. The dominant cost of most telecommunication networks is the access network itself, which typically can demand up to 80% of the total investment required.

Cogeneration, also called combined heat and power (CHP), refers to the use of a power station to deliver two or more useful forms of energy, for example, to generate electricity and heat at the same time. All conventional, fuel-based plants generate heat as by-product, which is often carried away and wasted. Cogeneration captures part of this heat for delivery to consumers and is thus a thermodynamically efficient use of fuel, and contributes to reduction of carbon emissions. This book provides an integrated treatment of cogeneration, including a tour of the available technologies and their features, and how these systems can be analysed and optimised.

Radio Man tells the story of C.O. Stanley, the unconventional Irishman who acquired Pye Radio at the beginning of the broadcasting age. Although he started with little experience and even less money, he was to make Pye a major player in the British electronics industry - only to crash it spectacularly forty years later. From the romance of early radio to the birth of the mobile, Stanley and Pye were players in some of the key moments of twentieth century Britain. His obsession with the infant medium of television allowed Pye to provide the equipment that put radar into planes in time for the Battle of Britain. His energy also drove Pye's pioneering work on the proximity fuse - work that would revolutionise antiaircraft warfare - and the company's manufacture of the war's most successful army radios.

In control theory, sliding mode control, or SMC, is a nonlinear control method that alters the dynamics of a nonlinear system by application of a discontinuous control signal that forces the system to 'slide' along a cross-section of the system's normal behaviour. This book describes recent advances in the theory, properties, methods and applications of SMC.

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.
