Download or read book RF Power Semiconductor Generator Application in Heating and Energy Utilization written by Satoshi Horikoshi and published by Springer Nature. This book was released on 2020-03-26 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a specialized book for researchers and technicians of universities and companies who are interested in the fundamentals of RF power semiconductors, their applications and market penetration.Looking around, we see that products using vacuum tube technology are disappearing. For example, branch tube TVs have changed to liquid crystal TVs, and fluorescent light have turned into LED. The switch from vacuum tube technology to semiconductor technology has progressed remarkably. At the same time, high-precision functionalization, miniaturization and energy saving have advanced. On the other hand, there is a magnetron which is a vacuum tube device for generating microwaves. However, even this vacuum tube technology has come to be replaced by RF power semiconductor technology. In the last few years the price of semiconductors has dropped sharply and its application to microwave heating and energy fields will proceed. In some fields the transition from magnetron microwave oscillator to semiconductor microwave oscillator has already begun. From now on this development will progress remarkably. Although there are several technical books on electrical systems that explain RF power semiconductors, there are no books yet based on users' viewpoints on actual microwave heating and energy fields. In particular, none have been written about exact usage and practical cases, to answer questions such as "What are the advantages and disadvantages of RF power semiconductor oscillator?", "What kind of field can be used?" and the difficulty of the market and application. Based on these issues, this book explains the RF power semiconductors from the user's point of view by covering a very wide range of fields.

Download or read book Nonlinear and Stochastic Climate Dynamics written by Christian L. E. Franzke and published by Cambridge University Press. This book was released on 2017-01-19 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now widely recognized that the climate system is governed by nonlinear, multi-scale processes, whereby memory effects and stochastic forcing by fast processes, such as weather and convective systems, can induce regime behavior. Motivated by present difficulties in understanding the climate system and to aid the improvement of numerical weather and climate models, this book gathers contributions from mathematics, physics and climate science to highlight the latest developments and current research questions in nonlinear and stochastic climate dynamics. Leading researchers discuss some of the most challenging and exciting areas of research in the mathematical geosciences, such as the theory of tipping points and of extreme events including spatial extremes, climate networks, data assimilation and dynamical systems. This book provides graduate students and researchers with a broad overview of the physical climate system and introduces powerful data analysis and modeling methods for climate scientists and applied mathematicians.

Available in PDF, EPUB and Kindle. Book excerpt: The first and only Druidic book of spells, rituals, and practice. The Druid Magic Handbook is the first manual of magical practice in Druidry, one of the fastest growing branches of the Pagan movement. The book breaks new ground, teaching Druids how to practice ritual magic for practical and spiritual goals within their own tradition. What sets The Druid Magic Handbook apart is that it does not require the reader to use a particular pantheon or set of symbols. Although it presents one drawn from Welsh Druid tradition, it also shows the reader how to adapt rites and other practices to fit the deities and symbols most meaningful to them. This cutting edge system of ritual magic can be used by Druids, Pagans, Christians, and Thelemites alike! This is the first manual of Druidic magical practice ever, replete with spell work and rituals.

Book excerpt: Broke, recently divorced, and a total deadbeat, Bob Wells has spent his life as a psychiatrist only doing good in the world. When one of his patients with clear paranoid delusions starts to lose a grip, Bob has no choice but to intervene. Emile Bardan is haunted by demons, and he believes that someone is trying to steal his most prized possesion, the legendeary Mask of Utu. Bob thinks it’s all part of Emile’s imagination until he discovers that Emile is telling the truth and that the mask is worth millions. It’s Bob who may actually be the one losing his grip. He’s tired of helping people for nothing, tired of being treated like dirt—and while he may have met the girl of his dreams, he doesn’t want to lose her because he can’t take care of her. There is only one thing to do: Bob is going to steal the mask himself: But doing so may mean making the biggest mistake of all—as he proceeds down a path into a dark abyss from which there is no return.

Download or read book Hawthorne in Concord written by Philip McFarland and published by Open Road + Grove/Atlantic. This book was released on 2007-12-01 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: A richly textured account of the writer’s three sojourns in New England “illuminates Hawthorne’s art and the intellectual ferment originating in that small, bucolic town” (Publishers Weekly). On his wedding day in 1842, Nathaniel Hawthorne escorted his new wife, Sophia, to their first home, the Old Manse in Concord, Massachusetts. There, enriched by friendships with Thoreau and Emerson, he enjoyed an idyllic time. But three years later, unable to make enough money from his writing, he returned ingloriously, with his wife and infant daughter, to live in his mother’s home in Salem. In 1853, Hawthorne moved back to Concord, now the renowned author of The Scarlet Letter and The House of the Seven Gables. Eager to resume writing fiction at the scene of his earlier happiness, he assembled a biography of his college friend Franklin Pierce, who was running for president. When Pierce won the election, Hawthorne was appointed the lucrative post of consul in Liverpool. Coming home from Europe in 1860, Hawthorne settled down in Concord once more. He tried to take up writing one last time, but deteriorating health found him withdrawing into private life. In Hawthorne in Concord, acclaimed historian Philip McFarland paints a revealing portrait of this well-loved American author during three distinct periods of his life, spent in the bucolic village of Concord, Massachusetts. “I don’t know when I have read a book as satisfying as Hawthorne in Concord.” —David Herbert Donald

Download or read book A Slice Through Time written by M.G.L. Baillie and published by Routledge. This book was released on 2012-10-12 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic development of European oak chronologies over the last ten years parallels and supplements the bristlecone-pine chronology in the United States. Dendrochronologists can now provide a wood sample - a time capsule of biological material - for any calender date over the last seven millennia from two continents. For archaeologists, resigned to the imprecision of radiocarbon dating, the implications are profound. For the first time it is possible to establish precise dates for prehistoric events. Similarly, we have an independent and scientifically objective way of testing historical accounts, such as the traditional Egyptian chronology. Equally fundamental are the insights provided by the related disciplines of dendroecology and dendroclimatology. The Bronze Age eruption of Santorini and the AD 540 `event' are explored as fascinating case studies. Drawing on a further decade of research by himself and others, Mike Baille not only brings the pre-1980 story up to date, but demonstrates the wide and exciting applications of this comparatively new science.
