This unique book provides the reader with a thorough background in almost every aspect of lightning and its impact on electrical and electronic equipment. The contents range from basic discharge processes in air through transient electromagnetic field generation and interaction with overhead lines and underground cables, to lightning protection and testing techniques. This book is of value to anyone designing, installing or commissioning equipment which needs to be secured against lightning strikes, as well as being a sound introduction to research students working in the field.
This book provides the theory, mathematics and computational tools that are necessary to model each and every one of the processes associated with lightning discharges. This is essential information for a newcomer to the subject as well as for experienced scientists working in this field. Indeed, it is only through exercising various models and mathematical simulations that one can understand the basics mechanisms associated with the generation and interactions of the electric and magnetic fields of thunderclouds and lightning. This book would appeal to undergraduate and post graduate Physics and Engineering Students, Lightning Protection and EMC Engineers and those working within the areas of Electrical Engineering, Computer engineering and Physics. This book provides the rules and computations procedures to bridge this physical understanding with high level computational procedures to model each and every electromagnetic process, whether static or dynamic, and their effects and interactions. This book makes it possible for the reader to apply the knowledge gained from these books such as The Lightning Flash, IET 2003 and Lightning Protection, IET 2010 and obtain first hand experience through simulations on the processes generating the electromagnetic field of thunderclouds and lightning flashes and the effects of these electromagnetic fields. They will also experience how the results described in these books will emerge when Maxwell's equations are combined with basic laws conservation laws of nature and physics of electrical discharges. Uniquely, the information provided in this book is not limited to lightning scientists and lightning protection engineers alone. The procedures used to study the interaction of lightning electromagnetic fields with structures, power lines and telecommunication systems can also be used to study the interaction of the said components with electromagnetic fields generated by any radio transmitter.
This book about lightning summarizes the essence of physics and effects of lightning in a non-technical manner and provides an up-to-date description of the phenomenon of lightning in simple language. Starting with the myths related to lightning, the reader is introduced to the mechanism of lightning flashes and their interactions with humans, human-made systems and Earth’s environment. Most of the available books on lightning are written for the experts in the field and there is a need for a book that introduces the undergraduate and beginning post graduate students to the subject of lightning and prepares them for more advanced books meant for the experts. This introductory book, which is based on a series of lectures given to undergraduate and postgraduate students in electrical engineering, is intended to fill this need. Tailored to the needs of university students who plan to study electrical engineering, meteorology, environmental or basic physics, it is also a valuable reference resource for laymen who are interested in knowing more on this phenomenon.
Part of the most critically acclaimed, best-selling, all-new line of volume one graphic novels, DC Universe Rebirth! His name is Barry Allen, and he’s the Fastest Man Alive. But he’s also so much more. As he learns more about the Speed Force that fuels his incredible powers, the Flash is also discovering secrets about his past beyond anything he’d ever dreamed-how he created a Flashpoint that changed history and helped create a new world, watched over by forces unknown. And when the same Speed Force that flows through him is unleashed all over Central City, striking cops, criminals and ordinary civilians alike, it’s up to the Flash to train this new wave of speedsters to use their amazing abilities wisely. But while some may become his partners in crime-fighting-forming a true “Speed Force”-others will use their godlike powers for a more sinister purpose. And the Flash is about to learn that there’s some evil even he can’t outrun… The race is on as writer Joshua Williamson (DEATHSTROKE) and artist Carmine di Giandomenico (All New X-Factor) present THE FLASH VOL. 1: LIGHTNING STRIKES TWICE-the starting line of a bold new era for the Scarlet Speedster, bursting from the blockbuster DC Universe Rebirth event! Collects THE FLASH: REBIRTH #1 and THE FLASH #1-8.

This fascinating account and analysis of how one woman’s near-death experience sparked an awakening into psychic consciousness will “inspire your to rethink . . . humanity, death, and an afterlife” (Bruce Greyson, MD, University of Virginia School of Medicine). When Elizabeth Greenfield Krohn got out of her car with her two young sons in the parking lot of her synagogue on a late afternoon in September 1988, she couldn't have anticipated she would within seconds be struck by lightning and have a near-death experience. She felt herself transported to a garden and engaging in a revelatory conversation with a spiritual being. When she recovered, her most fundamental understandings of what the world is and how it works had been completely transformed. She was “changed in a flash,” suddenly able to interact with those who had died and have prescient dreams predicting news events. She came to believe that some early traumatic and abusive experiences had played a part in preparing her for this experience. Told in matter-of-fact language, the first half of this book is the story of Krohn’s journey, and the second is an interpretation and analysis by respected professor of religion Jeffrey J. Kripal. He places Krohn’s experience in the context of religious traditions and proposes the groundbreaking idea that we are shaping our own experiences in the future by how we engage with near-death experiences in the present. Changed in a Flash is not about proving a story, but about carving out space for serious discussion of this phenomenon.
"With dedicated sections covering equipment, indoor and outdoor lighting, post production, case studies, and genres such as wedding, fashion, lifestyle, and boudoir, One light flash aims to show you how the first flash you buy may be the last you ever need."--Publisher's description.
Lightning represents a natural phenomenon of substantial interest. Due to its complex nature, research continues in many countries and reveals amazing results. Lightning is actively observed because of its relevance to Earth climate and air composition in addition to the classical aspects of related human fatalities and damage to forests, buildings, power lines, aircraft, structures and electronic devices. In this volume, the most important contemporary questions on lightning are addressed and analyzed under many experimental and theoretical aspects. Lightning detection techniques using ground-based and space-borne methods are described, along with network engineering and statistical analysis. Contributions detail research on atmospheric electricity, cloud physics, lightning physics, modeling of electrical storms and middle atmospheric events. Special phenomena such as triggered lightning and sprite observations are examined. Lightning-induced nitrogen oxides and their effects on atmospheric chemistry and climate are discussed. Each topic is presented by international experts in the field. Topics include: * air chemistry * convective storms * infrasound from lightning * lightning and climate change * lightning and precipitation * lightning and radiation * lightning and supercells * lightning and thunderstorms * lightning detection * lightning from space * lighting protection * lightning return strokes * observations and interpretations * spatial distribution and frequency * triggered lightning * weather extremes
