Wall bounded turbulent flows are of major importance in industrial and environmental fluid mechanics. The structure of the wall turbulence is intrinsically related to the coherent structures that play a fundamental role in the transport process. The comprehension of their regeneration mechanism is indispensable for the development of efficient strategies in terms of drag control and near wall turbulence management. This book provides an up-to-date overview on the progress made in this specific area in recent years.
This book provides a clear and authoritative introduction to the emerging Arab media industries in the context of globalization and its impacts, with a focus on publishing, press, broadcasting, cinema and new media. Through detailed discussions of the regulation and economics of these industries, the authors argue that the political, technological and cultural changes on the global media scene have resulted in the reorganization of the Arab media field. They provide striking examples of this through the particular effects on media policies, media technology and the content and genres developed for the new generation of media consumers. As part of the book's overview of the contemporary characteristics of Arab media, the authors outline the development of the role of modern Arab media from a tool of mobilizing the public to a tool of commercial and symbolic profit. Overall, the volume illustrates how the Arab region represents a unique case where the commercialization and liberalization of selected media industries has gone hand in hand with continuous state intervention and an increasing self censorship. Written for students without prior knowledge of the topic, Arab Media will be essential reading for all interested in the contemporary global media industries.

The second part of the book explores up-to-date applications of electromagnetic waves—including radiometry, geophysical remote sensing and imaging, and biomedical and signal processing applications. Written by a world renowned authority in the field of electromagnetic research, this new edition of Electromagnetic Wave Propagation, Radiation, and Scattering: From Fundamentals to Applications presents detailed applications with useful appendices, including mathematical formulas, Airy function, Abel’s equation, Hilbert transform, and Riemann surfaces. The book also features newly revised material that focuses on the following topics: Statistical wave theories—which have been extensively applied to topics such as geophysical remote sensing, bio-electromagnetics, bio-optics, and bio-ultrasound imaging Integration of several distinct yet related disciplines, such as statistical wave theories, communications, signal processing, and time reversal imaging New phenomena of multiple scattering, such as coherent scattering and memory effects Multiphysics applications that combine theories for different physical phenomena, such as seismic coda waves, stochastic wave theory, heat diffusion, and temperature rise in biological and other media Metamaterials and solitons in optical fibers, nonlinear phenomena, and porous media Primarily a textbook for graduate courses in electrical engineering, Electromagnetic Wave Propagation, Radiation, and Scattering is also ideal for graduate students in bioengineering, geophysics, ocean engineering, and geophysical remote sensing. The book is also a useful reference for engineers and scientists working in fields such as geophysical remote sensing, bio–medical engineering in optics and ultrasound, and new materials and integration with signal processing.
This book – a sequel of previous publications 'Flows and Chemical Reactions' and 'Chemical Reactions in Flows and Homogeneous Mixtures' – is devoted to flows with chemical reactions in heterogeneous environments. Heterogeneous media in this volume include interfaces and lines. They may be the site of radiation. Each type of flow is the subject of a chapter in this volume. We consider first, in Chapter 1, the question of the generation of environments biphasic individuals: dusty gas, mist, bubble flow. Chapter 2 is devoted to the study at the mesoscopic scale: particle-fluid exchange of momentum and heat with determination of the respective exchange coefficients. In Chapter 3, we establish simplified equations of macroscopic balance for mass, for the momentum and energy, in the case of particles of one size (monodisperse suspension). Radiative phenomena are presented in Chapter 5.
Radio’s influence can be found in almost every corner of new media. Radio in the Digital Age assesses a medium that has not only survived the challenges of a new technological age but indeed has extended its reach. This is not a book about digital radio, but rather about the medium of radio in its many analogue and digital forms in an age characterised by digital technologies. The context of the digital age reveals new insights about the nature of radio. In this important addition to the world of radio scholarship, Dubber provides a theoretical framework for understanding the medium – allowing for complexity and contradiction, while avoiding essentialism and technological determinism. Introducing radio as a series of practices and phenomena that can be understood through a range of discursive categories, this book explores the relationships between radio, music, politics, storytelling and society in a new and thoughtful way. This book will make essential reading for students of media, communication, broadcasting and the digital industries. It offers a timely and comprehensive introduction for anyone who wishes to understand the role of radio in today’s media landscape.
The current diversity of transport services, as well as the complexity resulting from the deployment of specific transport protocols or mechanisms over the different services provided by heterogeneous networks, demand a novel design of the transport layer. Moreover, current and future applications will only be able to take advantage of the most adapted and available transport services if they are able to interact (i.e. discover, compose, deploy and adapt) efficiently with this advanced transport layer. The work presented in this book proposes a model-driven methodology and a service-oriented approach aimed at designing the mechanisms, functions, protocols and services of the next generation transport layer. The first part of this book presents the state of the art of transport protocols and introduces a model-driven methodology and an ontology semantic model implementation aimed at designing next generation transport protocols. The second part presents the UML-based design of a component-based transport protocol. An extension to this protocol based on service-component and service-oriented architectures is also presented. The third part presents various model-driven adaptive strategies aimed at managing the behavioral and structural adaptation of next generation autonomic transport protocols. The fourth and final part presents the design of a transport layer based on component-oriented and service-oriented approaches and integrating the autonomic computing paradigm guided by the semantic dimension provided by ontologies.

Media, Markets, and Morals provides an original ethical framework designed specifically for evaluating ethical issues in the media, including new media. The authors apply their account of the moral role of the media, in their dual capacity as information providers for the public good and as businesses run for profit, to specific morally problematic practices and question how ethical behavior can be promoted within the industry. Brings together experts in the fields of media studies and media ethics, information ethics, and professional ethics Offers an original ethical framework designed specifically for evaluating ethical issues in the media, including new media Builds upon and further develops an innovative theoretical model for examining and evaluating media corruption and methods of media anti-corruption previously developed by authors Spence and Quinn Discloses and clarifies the inherent ethical nature of information and its communication to which the media as providers of information are necessarily committed
