In the last decade the development and control of Unmanned Aerial Vehicles (UAVs) has attracted a lot of interest. Both researchers and companies have a growing interest in improving this type of vehicle given their many civilian and military applications. This book presents the state of the art in the area of UAV Flight Formation. The coordination and robust consensus approaches are presented in detail as well as formation flight control strategies which are validated in experimental platforms. It aims at helping students and academics alike to better understand what coordination and flight formation control can make possible. Several novel methods are presented: – controllability and observability of multi-agent systems; – robust consensus; – flight formation control; – stability of formations over noisy networks; which generate solutions of guaranteed performance for UAV Flight Formation.

Environmental and Energy Law
Despite bringing prosperity, industrialisation generally leads to increasing levels of pollution which has a detrimental impact on the environment. In response, legislation which seeks to control or prevent such impact has become common. Similarly, climate change and energy security have become major drivers for the regulatory regimes that have emerged in the energy field. Given the global or regional scope of many environmental problems, international cooperation is often necessary to ensure such legislation is effective. The EU and the UK have contributed to the development of the environmental and energy law regimes currently in force, spanning across international, transnational and national levels. At the same time, practical responses to environmental and energy problems have largely been the focus of engineers, scientists and other technical experts. Environmental & Energy Law attempts to bridge the knowledge gap between legal developments designed to achieve environmental and/or energy-related objectives and the practical, scientific and technical considerations applicable to the same environmental problems. In particular, it attempts to convey a broad range of topical issues in environmental and energy law, from climate and energy regulation, technology innovation and transfer, to pollution control, environmental governance and enforcement. In addition the book outlines key sector specific legal regimes (including water, waste and air quality management), focusing on issues or topics that are particularly relevant to both environmental and energy lawyers, and engineering, science and technology-oriented professionals and students. In this vein, the book guides the reader on some basic practical applications of the law within scientific, engineering and other practical settings. The book will be useful to all those working or studying in the environmental or energy arena, including law students, legal professionals, engineering and science students and professionals. By adopting a multi-disciplinary approach to environmental and energy law, the book embraces all readerships and helps to address the often thorny problem of communication between scientists, engineers, lawyers and policy-makers.

Refrigeration Systems and Applications, 2nd edition forms a useful reference source for graduate and postgraduate students and researchers in academia and as well as practicing engineers working in this important field who are interested in refrigeration systems and applications and the methods and analysis tools for their analysis, design and performance improvement.
Transnationalizing the Public Sphere
Is Habermas’s concept of the public sphere still relevant in an age of globalization, when the transnational flows of people and information have become increasingly intensive and when the nation-state can no longer be taken granted as the natural frame for social and political debate? This is the question posed with characteristic acuity by Nancy Fraser in her influential article ‘Transnationalizing the Public Sphere?’ Challenging careless uses of the term ‘global public sphere’, Fraser raises the debate about the nature and role of the public sphere in a global age to a new level. While drawing on the richness of Habermas’s conception and remaining faithful to the spirit of critical theory, Fraser thoroughly reconstructs the concepts of inclusion, legitimacy and efficacy for our globalizing times. This book includes Fraser’s original article as well as specially commissioned contributions that raise searching questions about the theoretical assumptions and empirical grounds of Fraser’s argument. They are concerned with the fundamental premises of Habermas’s development of the concept of the public sphere as a normative ideal in complex societies; the significance of the fact that the public sphere emerged in modern states that were also imperial; whether ‘scaling up’ to a global public sphere means giving up on local and national publics; the role of ‘counterpublics’ in developing alternative globalization; and what inclusion might possibly mean for a global public. Fraser responds to these questions in detail in an extended reply to her critics. An invaluable resource for students and scholars concerned with the role of the public sphere beyond the nation-state, this book will also be welcomed by anyone interested in globalization and democracy today.
Sound Visualization and Manipulation
Unique in addressing two different problems – sound visualization and manipulation – in a unified way Advances in signal processing technology are enabling ever more accurate visualization of existing sound fields and precisely defined sound field production. The idea of explaining both the problem of sound visualization and the problem of the manipulation of sound within one book supports this inter-related area of study. With rapid development of array technologies, it is possible to do much in terms of visualization and manipulation, among other technologies involved with the spatial distribution of sound. This book aims to explore various basic functions for the visualization and manipulation and demonstrate to the reader how these properties determine the quality of visualization and manipulation. The first half of the book introduces some basic and general concepts and theories and the second part of the book explains a number of techniques in sound visualization and manipulation. It offers a unified presentation to two very different topics – sound field visualization techniques based on microphone arrays, and techniques for generation of controlled sound fields using loudspeaker arrays. The authors emphasize the similarities between these two physical problems and between the mathematical methods used for solving them. With extensive examples throughout the book, chapters include: Acoustic Wave Equation and its Basic Physical Measures, Acoustic Wave Equation and its Basic Physical Measures, Basic Theory of Sound Visualization, Acoustic Holography, Beamforming, Basic Theory of Sound Manipulation, Sound Focusing, and Sound Field Reproduction. The first book to combine both the visualization and manipulation of sound technologies in one comprehensive volume Presents the basic concepts using simple one dimensional cases and then extends the concept to three dimensional cases, enabling easier understanding of the fundamental concepts through the use of minimum mathematics Provides a solid understanding of associated physics as well as mathematical concepts for understanding the technologies, addressing diffraction problems in an integrated format by using Kirchhoff-Helmholtz integral equation Uses extensive examples demonstrating the benefits and drawbacks of various applications, including beamforming and acoustic holography A valuable resource forpost/graduate students, acoustic engineers, audio and noise control system developers
