Standard Codecs, 3rd Edition

Tue, 12 Jun 2018 01:34:09 GMT

A substantially updated edition of Video Coding: An introduction to standard codecs (IEE 1999, winner of IEE Rayleigh Award as the best book of 2000), this book discusses the growth of digital television technology, from image compression to advanced video coding. This third edition also includes the latest developments on H.264/MPEG-4 video coding and the scalability defined for this codec, which were not available at the time of the previous edition (IEE 2003). The book highlights the need for standardisation in processing static and moving images and extensively exploits the ITU and ISO/IEC standards defined in this field. The book gives an authoritative explanation of pictures and video coding algorithms, working from basic principles through to the advanced video compression systems now being developed. It discusses the reasons behind the introduction of a standard codec for a specific application and its chosen parameters. Each chapter is devoted to a standard video codec, and chapters are introduced in an evolutionary manner complementing the earlier chapters. This book will enable readers to appreciate the fundamentals needed to design a video codec for any given application and should prove a valuable resource for managers, engineers and researchers working in this field.

Coaxial Electrical Circuits for Interference-Free Measurements

Tue, 12 Jun 2018 00:40:50 GMT

The authors have between them more than 60 years of experience in making electrical measurements in National Measurement Laboratories. These laboratories are the source of measurement standards and techniques for science and engineering and are dedicated to maintaining the international system of units (SI) by establishing and disseminating the values of measurement standards with the lowest possible uncertainty. Careful attention to detail is required in designing measurement systems that eliminate electrical interference and are as simple and as close to first principles as possible. This book draws on their experience by offering guidance and best practice for designing sensitive electrical measurement circuits.

In particular the book describes examples that demonstrate the elegance, flexibility and utility of balanced-current coaxial networks in obtaining the ultimate in noise-matching and interference elimination for precise and accurate voltage, current and power measurements. It also updates an earlier book on coaxial AC bridges by including recent AC measurements of quantum Hall resistance to establish a primary quantum standard of impedance and by extending impedance measurements in general to higher frequencies.

The Correspondence of Michael Faraday

Tue, 12 Jun 2018 00:22:39 GMT

Michael Faraday (1791-1867) was one of the most important men of science in nineteenth century Britain. His discoveries of electro-magnetic 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 (including Trinity House), his religious beliefs and his lack of mathematical ability, make Faraday one of the most fascinating scientific figures ever. All these aspects of his life and work and others, such as his health, are reflected in his letters which, in this final volume, cover Faraday's life to his death in August 1867. Also published here are letters that could not be dated and letters that should have been included in volumes one to five but which had not been located when those volumes were published. In total just over 80% of the letters in this volume are previously unpublished. The dominant topic of the 1860s (covered in nearly 40% of the letters) is Faraday's involvement with the lighthouse service relating in particular to his advice to Trinity House and the Board of Trade on matters such as electric light and the controversial issue of fog signals. Also detailed is the complex process by which his various posts were transferred to John Tyndall. Similar issues existed with Faraday's gradual withdrawal from his duties at the Royal Institution, including the misguided attempt to make him President. And, of course, running through many of the letters are comments on his declining health and impending death. Major correspondents include the Astronomer Royal G.B. Airy, the Secretary of Trinity House P.H. Berthon, the Birmingham glassmaker J.T. Chance, the Assistant Secretary of the Board of Trade T.H. Farrer, the German mathematician Julius Plücker, the Cambridge trained mathematical natural philosophers James Clerk Maxwell and William Thomson, Faraday's colleagues at the Royal Institution Henry Bence Jones, John Tyndall and Benjamin Vincent, the Swiss chemist Christian Schoenbein and the astronomer James South.

Energy storage and in particular electrical storage of energy has become a very talked about topics in circles, ranging from lay person in regard to hybrid and battery electric vehicles, to professional and certainly by legislators and energy policy makers in government. But even to professional the distinction between physical and chemical forms of electric energy storage are unclear and at times poorly understood, if at all. This book takes a critical look at physical storage of electricity in the devices known collectively as electrochemical capacitors and particularly as ultracapacitors. In its 12 chapters, this text covers ultracapacitors and advances battery topics with emphasis on clear understanding of fundamental principles, models and applications. The reader will appreciates the case studies ranging from commercial to industrial to automotive applications of not only ultracapacitors but these power device components in combination with energy dense battery technologies.

Scenarios for a Future Electricity Supply

Mon, 11 Jun 2018 23:55:10 GMT

This book pursues the fundamental idea of using renewable energies in a rational and economic way in order to develop a climate-friendly electricity supply. As the most cost efficient solution, an electricity network for the whole of Europe and parts of Africa and Asia must be found. The sources of renewable and partly decentralised electricity generation could be connected in a comprehensive power supply to meet the electricity needs of an entire region.

Czisch examines different scenarios for a CO₂ neutral electricity system under different political, technological and economic conditions for Europe and its closer surroundings. The aim is to find in each variation the economically optimal solution, whereby the supply area embraces approximately 1.1 billion inhabitants and an electricity consumption of roughly 4000 terrawatt-hours per annum (TWh/a).

Energy Storage for Power Systems, 2nd Edition

Mon, 11 Jun 2018 23:25:51 GMT

The supply of energy from primary sources is not constant and rarely matches the pattern of demand from consumers. Electricity is also difficult to store in significant quantities. Therefore, secondary storage of energy is essential to increase generation capacity efficiency and to allow more substantial use of renewable energy sources that only provide energy intermittently. Lack of effective storage has often been cited as a major hurdle to substantial introduction of renewable energy sources into the electricity supply network. The author presents here a comprehensive guide to the different types of storage available. He not only shows how the use of the various types of storage can benefit the management of a power supply system, but also considers more substantial possibilities that arise from integrating a combination of different storage devices into a system. This book will be important to those seeking to develop environmentally sound energy resources.

Designing Electronic Systems for EMC

Mon, 11 Jun 2018 22:08:36 GMT

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.

The goal of all device and system designs that must function in an electromagnetic environment (i.e. radio, TV, radar, navigation, and communications) is to operate without adversely affecting other electronic equipment or systems. The inverse is also true. The requirement for sharing spectrum has reached international levels of concern and it must be dealt with in proportion to the safety and economic impact involved. Designing Electronic Systems for EMC outlines how.

Eigenstructure Control Algorithms

Mon, 11 Jun 2018 21:16:49 GMT

Eigenstructure control involves modification of both the eigenvalues and eigenvectors of a system using feedback. Based on this key concept, algorithms are derived for the design of control systems using controller structures such as state feedback, output feedback, observer-based dynamic feedback, implicit and explicit modelfollowing, etc. The simple-to-use algorithms are well suited to evolve practical engineering solutions.

The design of control laws for modern fly-by-wire high performance aircraft/rotorcraft offers some unique design challenges. The control laws have to provide a satisfactory interface between the pilot and the vehicle that results in good handling qualities (HQ) in precision control tasks. This book, through detailed aircraft and rotorcraft design examples, illustrates how to develop practical, robust flight control laws to meet these HQ requirements.

This book demonstrates that eigenstructure control theory can be easily adapted and infused into the aircraft industry's stringent design practices; therefore practicing flight control engineers will find it useful to explore the use of the new design concepts discussed. The book, being interdisciplinary in nature, encompassing control theory and flight dynamics, should be of interest to both control and aeronautical engineers. In particular, control researchers will find it interesting to explore an extension of the theory to new multivariable control problem formulations. Finally, the book should be of interest to graduate/doctoral students keen on learning a multivariable control technique that is useful in the design of practical control systems.

Advanced Control for Constrained Processes and Systems

Mon, 11 Jun 2018 21:07:00 GMT

This book provides a unified, practically-oriented treatment to many constrained control paradigms. Recently proposed control strategies are unified in a generalised framework to deal with different kinds of constraints. The book's solutions are based on reference conditioning ideas implemented by means of supervisory loops, and they are complementary to any other control technique used for the main control loop. Although design simplicity is a book priority, the use of well established sliding mode concepts for theoretical analysis make it also rigorous and self-contained.

The first part of the book focuses on providing a simple description of the method to deal with system constraints in SISO systems. It also illustrates the design and implementation of the developed techniques through several case studies. The second part is devoted to multivariable constrained control problems: improving system decoupling under different plant or controller constraints, and reducing the undesired effects caused by manual-automatic or controller switching. The key aim of this book is to reduce the gap between the available constrained control literature and industrial applications.

Adaptive Sampling with Mobile WSN

Mon, 11 Jun 2018 21:05:27 GMT

Adaptive Sampling with Mobile WSN develops algorithms for optimal estimation of environmental parametric fields. With a single mobile sensor, several approaches are presented to solve the problem of where to sample next to maximally and simultaneously reduce uncertainty in the field estimate and uncertainty in the localisation of the mobile sensor while respecting the dynamics of the time-varying field and the mobile sensor. A case study of mapping a forest fire is presented. Multiple static and mobile sensors are considered next, and distributed algorithms for adaptive sampling are developed resulting in the Distributed Federated Kalman Filter. However, with multiple resources a possibility of deadlock arises and a matrix-based discrete-event controller is used to implement a deadlock avoidance policy. Deadlock prevention in the presence of shared and routing resources is also considered. Finally, a simultaneous and adaptive localisation strategy is developed to simultaneously localise static and mobile sensors in the WSN in an adaptive manner. Experimental validation of several of these algorithms is discussed throughout the book.

Model-Based Requirements Engineering

Mon, 11 Jun 2018 20:59:16 GMT

This book provides a hands-on introduction to model-based requirements engineering and management by describing a set of views that form the basis for the approach. These views take into account each individual requirement in terms of its description, but then also provide each requirement with meaning by putting it into the correct 'context'. A requirement that has been put into a context is known as a 'use case' and may be based upon either stakeholders or levels of hierarchy in a system. Each use case must then be analysed and validated by defining a combination of scenarios and formal mathematical and logic-based proofs that provide the rigour required for safety-critical and mission-critical systems.

The book also looks at the crucial question of modelling notations for requirements modelling and includes discussions on the use and application of SysML, text and tabular formats.

Pragmatic issues, such as tailoring the approach for short, non-critical projects to massive, mission-critical projects is discussed to show how the techniques introduced in the book can be applied on real-life projects and systems. The use of multiple tools will also be discussed, along with examples of how an effective process can lead to realisation by any tool.

Foliage Penetration Radar

Wed, 16 May 2018 16:51:47 GMT
