Book Synopsis Gas Discharge Closing Switches by : Gerhard Schaefer
Download or read book Gas Discharge Closing Switches written by Gerhard Schaefer and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulsed power technology, in the simplest of terms, usually concerns the storage of electrical energy over relatively long times and then its rapid release over a comparatively short period. However, if we leave the definition at that, we miss a multitude of aspects that are important in the ultimate application of pulsed power. It is, in fact, the application of pulsed power technology to which this series of texts will be focused. Pulsed power in today's broader sense means "special power" as opposed to the tra ditional situation of high voltage impulse issues related to the utility industry. Since the pulsed power field is primarily application driven, it has principally an engineering flavor. Today' s applications span those from materials processing, such as metal forming by pulsed magnetic fields, to other varied applications, such as psy chedelic strobe lights or radar modulators. Very high peak power applications occur in research for inertial confinement fusion, the Strategic Defense Initiative and other historical defense uses. lri fact it is from this latter direction that pulsed power has real ized explosive growth over the past half century. Early thrusts were in electrically powered systems that simulated the environment or effects of nuclear weapons detonation. More recently it is being utilized as prime power sources for directed energy weapons, such as lasers, microwaves, particle beam weapons, and even mass drivers (kinetic energy weapons).
Download or read book Simplexity written by Alain Berthoz and published by Odile Jacob. This book was released on 2018-12-20 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].
Book Synopsis European Communications Law and Technological Convergence by : Pablo Ibáñez Colomo
Download or read book European Communications Law and Technological Convergence written by Pablo Ibáñez Colomo and published by Kluwer Law International B.V.. This book was released on 2011-12-14 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a thorough critical examination of the European regulatory reaction to technological convergence, tracing the explicit and implicit mechanisms through which emerging concerns are incorporated into regulation and competition law, and then goes on to identify the patterns that underlie these responses so as to establish the extent to which the issues at stake, and the implications of intervention, are fully understood and considered by authorities. Focusing on ‘conflict points’ – areas of tension inevitably arising among overlapping regimes – the analysis covers such elements as the following: the provision of ‘multiple-play’ services; the advent of ‘convergent devices’; the interchangeability of transmission networks; subscription-based (‘pay television’) services; the diversification of television services (such as on-demand and niche-theme channels); the relative scarcity of (premium) content; the ‘migration’ of television content with cultural and social relevance to pay television; and the emergence of ‘bottleneck’ segments in the communications value chain. Endorsing the adjustment of existing rules to meet pluralist objectives, the author outlines a single, coherent regulatory approach. He shows how a careful analysis of the implications of technological convergence helps to solve conflicts between regimes. Specifically, the analysis addresses the level – national or EU – at which particular regulatory responses should emerge, the objectives guiding action, and the tools through which these objectives may be pursued. These conclusions command the attention of policymakers, regulators, and lawyers active in the ongoing development of communications law.

This book was released on 2001-11-30 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in computer applications has led to a new attitude to applied logic in which researchers tailor a logic in the same way they define a computer language. In response to this attitude, this text for undergraduate and graduate students discusses major algorithmic methodologies, and tableaux and resolution methods. The authors focus on first-order logic, the use of proof theory, and the computer application of automated searches for proofs of mathematical propositions.

Book Synopsis The Economic Regulation of Broadcasting Markets by : Paul Seabright
Download or read book The Economic Regulation of Broadcasting Markets written by Paul Seabright and published by Cambridge University Press. This book was released on 2007-04-26 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: New technology is revolutionizing broadcasting markets. As the cost of bandwidth processing and delivery fall, information-intensive services that once bore little economic relationship to each other are now increasingly related as substitutes or complements. Television, newspapers, telecoms and the internet compete ever more fiercely for audience attention. At the same time, digital encoding makes it possible to charge prices for content that had previously been broadcast for free. This is creating new markets where none existed before. How should public policy respond? Will competition lead to better services, higher quality and more consumer choice - or to a proliferation of low-quality channels? Will it lead to dominance of the market by a few powerful media conglomerates? Using the insights of modern microeconomics, this book provides a state-of-the-art analysis of these and other issues by investigating the power of regulation to shape and control broadcasting markets.
