Available in PDF, EPUB and Kindle. Book excerpt: The subject of geomagnetic micropulsations has developed extremely rapidly and it is difficult to know when is an appropriate time to pause and assess the sum total of our knowledge-both observational and theoretical. There has in recent years been a tremendous increase in both the quantity and quality of data and also many theoretical ad vances in our understanding of the phenomenon. Undoubtedly there will be further progress in both areas but it seems worthwhile now to review both our knowledge and our ignorance. This book was essen tially completed by the end of April 1969 and tries to give a summary of the subject up to that time. The Earth is enclosed in the magnetosphere, a hollow carved out of the solar wind by the Earth's magnetic field. Above the ionosphere there is a very tenuous thermal plasma of partially ionized hydrogen in diffusive equilibrium with magnetic and gravitational forces, and ener getic protons and electrons that constitute the trapped Van Allen ra diation belts. Throughout this anisotropic and inhomogeneous plasma, natural and man-made electromagnetic energy propagates in a wide variety of modes and frequency bands. This book is concerned with that class of natural signals called geomagnetic micropulsations-short period (usually of the order of seconds or minutes) fluctuations of the Earth's magnetic field.

Download or read book Schumann Resonance for Tyros written by Alexander Nickolaenko and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schumann resonance has been studied for more than half a century. The field became popular among researchers of the terrestrial environment using natural sources of electromagnetic radiation—lightning strokes, primarily—and now many Schumann observatories have been established around the world. A huge number of publications can be found in the literature, the most recent collection of which was presented in a special Schumann resonance section of the journal Radio Science in 2007. The massive publications, however, impede finding information about how to organize measurements and start observations of global electromagnetic resonance. Relevant information is scattered throughout many publications, which are not always available. The goal of this book is to collect all necessary data in a single edition in order to describe the demands of the necessary equipment and the field-site as well as the impact of industrial and natural interference, and to demonstrate typical results and obstacles often met in measurements. The authors not only provide representative results but also describe unusual radio signals in the extremely low-frequency (ELF) band and discuss signals in the adjacent frequency ranges.

Download or read book Extreme Events in Geospace written by Natalia Buzulukova and published by Elsevier. This book was released on 2017-12-01 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme Events in Geospace: Origins, Predictability, and Consequences helps deepen the understanding, description, and forecasting of the complex and inter-related phenomena of extreme space weather events. Composed of chapters written by representatives from many different institutions and fields of space research, the book offers discussions ranging from definitions and historical knowledge to operational issues and methods of analysis. Given that extremes in ionizing radiation, ionospheric irregularities, and geomagnetically induced currents may have the potential to disrupt our technologies or pose danger to human health, it is increasingly important to synthesize the information available on not only those consequences but also the origins and predictability of such events. Extreme Events in Geospace: Origins, Predictability, and Consequences is a valuable source for providing the latest research for geophysicists and space weather scientists, as well as industries impacted by space weather events, including GNSS satellites and radio communication, power grids, aviation, and human spaceflight. The list of first/second authors includes M. Hapgood, N. Gopalswamy, K.D. Leka, G. Barnes, Yu. Yermolaev, P. Riley, S. Sharma, G. Lakhina, B. Tsurutani, C. Ngwira, A. Pulkkinen, J. Love, P.

Download or read book Numerical Electromagnetics written by Umran S. Inan and published by Cambridge University Press. This book was released on 2011-04-07 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the development of finite difference equations, and leading to the complete FDTD algorithm, this is a coherent introduction to the FDTD method (the method of choice for modeling Maxwell's equations). It provides students and professional engineers with everything they need to know to begin writing FDTD simulations from scratch and to develop a thorough understanding of the inner workings of commercial FDTD software. Stability, numerical dispersion, sources and boundary conditions are all discussed in detail, as are dispersive and anisotropic materials. A comparative introduction of the finite volume and finite element methods is also provided. All concepts are introduced from first principles, so no prior modeling experience is required, and they are made easier to understand through numerous illustrative examples and the inclusion of both intuitive explanations and mathematical derivations.

Download or read book Architect s Guide to Feng Shui written by Cate Bramble and published by Routledge. This book was released on 2007-06-01 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cate Bramble has devoted her career to highlighting the differences between 'feng shui-lite' as a fashionable pursuit in contrast to the original intentions of the Chinese masters. Here she presents the authentic principles in a technical, no-nonsense pocket book specifically for architects. As clients become more demanding and the competition for projects heats up, the architect is well advised to have many strings to their bow. This practical guide includes line illustrations that present the principles of feng shui, the Chinese art or practice in which a structure or site is chosen or configured so as to harmonize with the spiritual forces that inhabit it, and their application in architecture through planning principles, services, building elements and materials, in an accessible, easy reference format. The feng shui-savvy architect can also benefit from feng shui's ability to match structures and land, and the peculiar capacity of authentic feng shui to forecast development-related concerns including cost overruns, quality issues - even worker injuries and trade disputes! The author explains feng shui from archaeological sources and evidence of practice in the east, contrasting it with what passes for feng shui in the west. She analyses the practice in terms of such concepts as western systems theory, viewshed, space syntax and the 'pattern landscape' theory of urban planning. For the first time, the Sustainable implications of feng shui design are explained with reference to the latest developments in behavioural and cognitve sciences, evolutionary biology and other western viewpoints.

Download or read book Ring Current Investigations written by Vania K. Jordanova and published by Elsevier. This book was released on 2020-06-18 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ring Current Investigations offers a comprehensive description of ring current dynamics in the Earth’s magnetosphere as part of the coupled magnetosphere-ionosphere system. In order to help researchers develop a deeper understanding of the fundamental physics of geomagnetic storms, it includes a detailed description of energetic charged particles injection, trapping, and loss. It reviews historical and recent advances in observations, measurements, theory and simulations of the inner magnetosphere and its coupling to the ionosphere and other surrounding plasma populations. In addition, it compares the physics of ring currents at other strongly magnetized planets in the solar system, specifically Jupiter, Saturn, Uranus and Neptune, with the ring current system at Earth. Providing a description of the most important space weather effects driven by inner magnetospheric energetic particles during geomagnetic storms and present capabilities for their nowcast and forecast, Ring Current Investigations is an important reference for researchers in geophysics and space science, especially related to plasma physics, the ionosphere and magnetosphere, solar-terrestrial relations, and spacecraft anomalies. Includes an appendix with links to downloadable video clips, illustrating features of ring current and geomagnetic storm dynamics Provides overview of existing state-of-the-art numerical models and links for open-source code downloads Offers guidance on how to develop numerical models within the context of the present-day understanding

Download or read book Into the Bermuda Triangle written by Gian Quasar and published by McGraw Hill Professional. This book was released on 2005-02-28 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Still unsolved, still baffling, still claiming new victims. Here are the untold stories. A pilot reports a strange haze enveloping his plane, then disappears; eleven hours after fuel starvation, as if calling from a void, he is heard 600 miles away. He requests permission to land, then vanishes forever. A freighter steaming over placid seas disappears without a trace. A pleasure yacht ghosts past without a soul on board. A pilot calls for help because a "weird object" is harassing his plane. A jet collides with an "unknown" and is never found. . . . Into the Bermuda Triangle is the first comprehensive examination of these baffling disappearances in more than a generation. Drawing on official reports from the NTSB and other investigative agencies as well as interviews with scientists, theorists, and survivors, leading authority Gian Quasar not only sets the record straight on previously examined cases, he also offers a bulging file of new cases, the collective results of his twelve-year investigation. In meticulous detail this unflinching account: Documents confirmed disappearances of airplanes and ships Gathers new testimony and reexamines old interviews from eyewitnesses and survivors Explores possible explanations ranging from zero-point energy to magnetic vortices Challenges our assumptions with the sheer weight of accumulated evidence In this age of technological and scientific discovery, there are still mysteries that transcend understanding. The Bermuda Triangle is one. "The best book I've ever read on this important subject."—Andrew Griffin, The Town Talk
