Electromagnetic Fields, Environment and Health
by Anne Perrin Martine SouquesA good number of misconceptions are currently circulating on the effects of non-ionizing radiations on our health, which can lead to an oversimplification of the issue, to potentially dangerous assumptions or to misleading data analysis. Health effects may be exaggerated, or on the contrary underplayed. The authors of this work (doctors, engineers and researchers) have endeavored to supply validated and easily understandable scientific information on the electromagnetic fields and their biological and health effects. After a general review of the physics of the waves and a presentation of non-ionizing radiations, the authors review the main emission sources encountered in our daily environment. They summarize simply but as accurately as possible the current knowledge on their biological effects. The safety limits recommended by international organizations are presented for the different frequency ranges. This book is intended for doctors, teachers, scientists, students, policy makers and anyone else interested in a deeper understanding of the health effects of electromagnetic fields. Intended to serve a broad readership, everyone will approach it according to their respective level of curiosity and knowledge. It is neither an exhaustive inventory of all the studies made to date, nor a survey text focusing only on some chosen studies. Nor is the objective to present all the sources of non-ionizing radiations. Interested readers will be given the opportunity to broaden their knowledge, also by consulting the selected bibliography presented by the authors at the end of each chapter.
Electromagnetic Performance Analysis of Graded Dielectric Inhomogeneous Radomes (SpringerBriefs in Applied Sciences and Technology)
by P. Mahima M. Suprava S. Vandana Mohammed P.S. Yazeen Raveendranath U. NairThis book reports on a new radome wall configuration based on an inhomogeneous planar layer, which overcomes current fabrication constraints in radome design and yields improved electromagnetic (EM) characteristics. The book also includes a detailed description of radomes and antenna-radome interaction studies for different radome wall configurations. The radome wall was designed using the equivalent transmission line method (EQTLM), since it requires less computational speed and provides accurate results. In order to substantiate the accuracy of the results obtained using EQTLM, the simulated results based on full wave methods like CST Microwave Studio Suite are also included. The EM performance analysis of the antenna-radome system for two radome shapes, tangent ogive (for airborne applications) and hemispherical (for ground-based applications), was performed using Geometric Optics Method in conjunction with the Aperture Integration Method. To show the efficacy of the new design, a comparison of performance characteristics between the novel radome and conventional wall configurations is also included. Lastly, it presents antenna-radome interaction studies for various aperture distributions. The book offers a unique resource for all researchers working in the area of microwave radomes.
Electromagnetic Theory and Plasmonics for Engineers
by Liudmila NickelsonThis book presents the theory of electromagnetic (EM) waves for upper undergraduate, graduate and PhD-level students in engineering.

Electromechanical Transmitters for ELF/VLF Radio (Synthesis Lectures on Engineering, Science, and Technology)
by Jarred S. Glickstein Soumyajit MandalThis book describes a new, extremely low frequency (ELF)/ very low frequency (VLF) miniaturized transmitter concept, based on the mechanical motion of permanent magnets or electrets. The authors explain how utilizing the very high energy density of modern ferromagnetic and ferroelectric materials, such “electromechanical transmitters’’ can provide much higher field generation efficiency than conventional antennas, thus enabling practical ELF/VLF wireless communications links. The text begins with the fundamental challenges of such links and provides an historical overview of the attempts that have been made to address these challenges. It then focuses on the design and implementation of practical electromechanical ELF/VLF transmitters, which is an interdisciplinary subject that spans multiple research areas including electromagnetics, power electronics, control systems, and mechanical design. The authors also describe how such transmitters can be combined with receivers and signal processing algorithms to realize complete ELF/VLF links in challenging environments.
The Electronic Communications Code and Property Law: Practice and Procedure
by Falcon ChambersLife now without access to electronic telecommunications would be regarded as highly unsatisfactory by most of the UK population. Such ready access would not have been achieved without methodical and ultimately enforceable means of access to the land on which to install the infrastructure necessary to support the development of an electronic communications network. Successive governments have made such access a priority, regarding it as a principle that no person should unreasonably be denied access to an electronic communications network or electronic communications services. The enactment of the Telecommunications Act 1984 and its revision by the Communications Act in 2003 have played their role in the provision of an extensive electronic infrastructure in the UK, while their reshaping by means of the Digital Economy Act 2017 will continue that process. Throughout that process, a little publicised series of struggles has taken place between telecommunications operators and landowners, as they seek to interpret the Electronic Communications Code by which their rights and obligations have been regulated. This book describes the problems that accompanied the Old Code (which will continue to regulate existing installations and agreements); and the intended solutions under the New Code. The eminent team of authors explain the background, provisions and operation of the old code and the new one, providing practical and jargon-free guidance throughout. It is sure to become the reference on this topic and is intended as a guide for telecommunications operators, land owners, and of course for their advisers in the legal and surveying professions. All members of Falcon Chambers, comprising nine Queen’s Counsel and 30 junior barristers, specialise in property law and allied topics, including the various incarnations of the Electronic Communications Code. Members of Falcon Chambers, including all the authors of this new work, have for many years lectured and written widely on the code, and have appeared (acting for both operators and landowners) in many of the few reported cases on the subject of the interface between property law and the code, including for example: Geo Networks Ltd v The Bridgewater Canal Co. Ltd (2010); Geo Networks Ltd v The Bridgewater Canal Co. Ltd (2011); Crest Nicholson (Operations) Ltd v Arqiva Services Ltd (2015); Brophy v Vodafone Ltd (2017).
Electronic Communications for Technicians
by Tom WheelerWritten by a technician for technicians, this book fills the gap between communications books that are either highly mathematical (suitable for engineers) or technically weak (not enough detail for technical learners). Using an algebra-based approach that does NOT sacrifice depth of coverage, it uses plain language and an abundance of examples and case studies to explore real circuits, systems, and their troubleshooting. Coverage includes electronic communications technologies, beginning with coverage of signals and modulation methods and ranging through the most current communications techniques, including cellular, PCS, GPS, and HDTV, and TCP/IP. The text gives comprehensive troubleshooting information as well as instruction in the correct use of test equipment in the field. This textbook is appropriate for undergraduate studies in analog and digital electronic communications and networking fundamentals, especially those courses aimed at practitioners in the field (technicians), but also possibly engineering technologists. It can be used to fulfill both analog and digital communications tracks in a curriculum.
The Electronic Grapevine: Rumor, Reputation, and Reporting in the New On-line Environment (LEA Telecommunications Series)
by Kerric Harvey Diane L. BordenThe widespread use of the Internet as a tool for gathering and disseminating information raises serious questions for journalists--and their readers--about the process of reporting information. Using virtual sources and publishing online is changing the way in which journalism takes place and its effect on the society it serves. USE LAST THREE PARAGRAPHS ONLY FOR GENERAL CATALOGS... The Electronic Grapevine explores the use of online media by reporters in the United States, and examines the impact that usage may have on how journalism is framed in the cultural sphere, as well as how it is conducted in the professional one. It contains a mix of material examining how it feels to "do" online journalism, how it affects those who consume it, different ways that media scholars go about trying to understand it better, and the likely social and cultural impact of Internet-like technologies on the public, at whom all this electronic information is eventually aimed. Drawing from the emerging scholarly work in the field and from the real-life experiences of working journalists, Borden and Harvey collect contributions that examine why journalists use the Internet, what changes it makes in how they approach their jobs, and what differences they see in conducting their daily newsgathering with this medium rather than other methods. The volume also analyses when and why journalists do not use online media and what the impact of the decision to use or not use the Internet may mean for the outer world, whose perceptions of itself are so often shaped by journalistic portrait. This series of thought-provoking, original essays explores the impact of computer-based information and communication services on traditional journalistic routines and practices, and thereby addresses a critical gap in the scholarly literature on communication, law, and culture. Distinguishing between linkage devices like the Internet, and database resources such as LEXIS/NEXIS, America Online, and others, this book examines the ways in which both types of online services may reshape and redefine not only the products of journalistic effort, but the newsgathering process itself.

Electronic Quills: A Situated Evaluation of Using Computers for Writing in Classrooms (Technology and Education Series)
by Bertram C. Bruce Andee Rubin with contributi Barnhardt and TeachersThis volume centers on the words and experiences of teachers and students who used QUILL -- a software package developed by the authors to aid in writing instruction. It looks in detail at the stories of these early users and considers questions relevant for other teachers, students, researchers, and developers of educational innovations. Questions posed include: * What does it mean to develop an environment for literacy in an actual classroom? * How can a teacher create an environment in which students work together toward meaningful goals? * How can a teacher promote the rich communication so necessary for developing language? * What is the role of technology in the practice and development of literacy? The examination of the QUILL experiences provides a fuller and more revealing account of what it meant to use QUILL than would have been possible through standard evaluation techniques. At the same time, the focus on the particulars also finds analogues in analyses of similar pieces of open-ended software or educational innovations in general.

Electronic Technology and Civil Procedure
by Zoltán Nemessányi Miklós KengyelThe effect of modern and communication technology on civil procedure first appeared on the agenda of the conference organized by the International Association of Procedural Law in 1999, verifying Lord Woolf's statement from the 90's, that "IT will not only assist in streamlining and improving our existing systems and process; it is also likely, in due course, itself to be catalyst for radical change as well...". At the conference in Pecs in the autumn of 2010 participants from three continents and twenty-five countries examined all aspects of the impact of modern information technology on civil procedure beginning with the electronic submission of the application, ranging from electronic service of documents and electronic means of proof supported by modern information technology. In addition to the practical issues they discussed the possible impact of electronic procedures on traditional principles of civil procedure. The conference book contains seven main reports and eleven correferates, the foreword was written by Prof. Peter Gottwald, the President of the International Association of Procedural Law.

Electronic Tribes
by Tyrone L. Adams Stephen A. SmithWhether people want to play games and download music, engage in social networking and professional collaboration, or view pornography and incite terror, the Internet provides myriad opportunities for people who share common interests to find each other. The contributors to this book argue that these self-selected online groups are best understood as tribes, with many of the same ramifications, both positive and negative, that tribalism has in the non-cyber world. In Electronic Tribes, the authors of sixteen competitively selected essays provide an up-to-the-minute look at the social uses and occasional abuses of online communication in the new media era. They explore many current Internet subcultures, including MySpace. com, craftster. org, massively multiplayer online role-playing games (MMORPGs) such as World of Warcraft, music downloading, white supremacist and other counterculture groups, and Nigerian e-mail scams. Their research raises compelling questions and some remarkable answers about the real-life social consequences of participating in electronic tribes. Collectively, the contributors to this book capture a profound shift in the way people connect, as communities formed by geographical proximity are giving way to communities - both online and offline - formed around ideas.

Elegant Jeremiahs: The Sage from Carlyle to Mailer (Routledge Revivals)
by George P. LandowLabelled "an elegant Jeremiah" by a journalist of his day, the urbane Victorian Matthew Arnold must have received the comparison with the Old Testament prophet uneasily. Writing in the 1970s, Norman Mailer seems to owe nothing to the biblical for his description of a long hot wait to buy a cold drink while reporting on the first voyage to the moon. Yet both Arnold and Mailer, George P. Landow asserts in this book, are sages, writers in the nonfiction prose form of secular prophecy, a genre richly influenced by the episodic structures and harshly critical attitudes toward society which characterize Old Testament prophetic literature. In this book, first published in 1986, Landow defines the genre by exploring its rhetoric, an approach that enables him to illuminate the relationships among representative works of the nineteenth century to one another, to biblical, oratorical, and homiletic traditions, and to such twentieth-century writers as Lawrence, Didion, and Mailer.
