Download or read book Statistical Analysis of Shortwave Fadeout Occurrence for the Years 1955 to 1969 written by Richard G. Hendl and published by . This book was released on 1973 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shortwave fadeout data for the period 1955 through 1969 were analyzed and correlated with solar flare data for the same period. Details of the analysis are presented along with various statistical presentations of the data. The validity of computerized objective procedures for matching geophysical data is shown. Some doubt is cast on the quality of the shortwave fadeout data during the early part of the period considered. (Author).
Book Synopsis Correlations of Solar and Geophysical Parameters-shortwave Fadeouts and Solar Optical Features by : Ronald T. Podsiadlo
Download or read book Correlations of Solar and Geophysical Parameters-shortwave Fadeouts and Solar Optical Features written by Ronald T. Podsiadlo and published by . This book was released on 1973 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shortwave fadeout durations are compared with associated solar flare characteristics and other features of the solar regions in which the flares occur. Statistical tests show that flare parameters, especially flare importance, have the highest correlations with shortwave fadeout duration. Most other active region features, such as plage area, also show some correlation, but to varying lesser degrees. Cross tabulations of the shortwave fadeout durations and optical features are presented and discussed relative to their use as operational space forecasting aids. (Author).

Book Synopsis Ionospheric Prediction and Forecasting by : Bruno Zolesi
Download or read book Ionospheric Prediction and Forecasting written by Bruno Zolesi and published by Springer Science & Business Media. This book was released on 2013-09-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how to predict and forecast the state of planet Earth’s ionosphere under quiet and disturbed conditions in terms of dynamical processes in the weakly ionized plasma media of the upper atmosphere and their relation to available modern measurements and modelling techniques. It explains the close relationship between the state of the media and the radio wave propagation conditions via this media. The prediction and forecasting algorithms, methods and models are oriented towards providing a practical approach to ionospherically dependent systems design and engineering. Proper understanding of the ionosphere is of fundamental practical importance because it is an essential part of telecommunication and navigation systems that use the ionosphere to function or would function much better in its nonappearance on the Earth and on any planet with an atmosphere.
Book Synopsis Room Acoustics by : Heinrich Kuttruff
Download or read book Room Acoustics written by Heinrich Kuttruff and published by CRC Press. This book was released on 2016-10-03 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well established as a classic reference and specialised textbook, since its first publication in 1973, Heinrich Kuttruff’s Room Acoustics combines detailed coverage with a state of art presentation of the theory and practice of sound behaviour in closed spaces. This sixth edition presents several additional new sections, for instance on the reflection of a spherical wave from a wall, on finite element methods for sound field calculation and on virtual reality, as well as giving an overhaul of the standard material. Particular emphasis is given to the properties and calculation of reverberation, the most obvious acoustical feature of a room. And further key topics include the various mechanisms of sound absorption and their practical application as well as scattering by wall irregularities including pseudo-stochastic structures. Extensive space is given to of psychoacoustic insights and the quality criteria derived from them, along with new procedures for the sensory assessment of concert hall acoustics. As in earlier editions, one full and updated chapter is devoted to the design and performance of electroacoustic systems which nowadays is not just a method for sound amplification but offers many possibilities for correcting acoustic deficiencies and modifying a hall’s natural acoustics.

Book Synopsis History of Wireless by : T. K. Sarkar
Download or read book History of Wireless written by T. K. Sarkar and published by John Wiley & Sons. This book was released on 2006-01-17 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Important new insights into how various components and systems evolved Premised on the idea that one cannot know a science without knowing its history, History of Wireless offers a lively new treatment that introduces previously unacknowledged pioneers and developments, setting a new standard for understanding the evolution of this important technology. Starting with the background-magnetism, electricity, light, and Maxwell's Electromagnetic Theory-this book offers new insights into the initial theory and experimental exploration of wireless. In addition to the well-known contributions of Maxwell, Hertz, and Marconi, it examines work done by Heaviside, Tesla, and passionate amateurs such as the Kentucky melon farmer Nathan Stubblefield and the unsung hero Antonio Meucci. Looking at the story from mathematical, physics, technical, and other perspectives, the clearly written text describes the development of wireless within a vivid scientific milieu. History of Wireless also goes into other key areas, including: The work of J. C. Bose and J. A. Fleming German, Japanese, and Soviet contributions to physics and applications of electromagnetic oscillations and waves Wireless telegraphic and telephonic development and attempts to achieve transatlantic wireless communications Wireless telegraphy in South Africa in the early twentieth century Antenna development in Japan: past and present Soviet quasi-optics at near-mm and sub-mm wavelengths The evolution of electromagnetic waveguides The history of phased array antennas Augmenting the typical, Marconi-centered approach, History of Wireless fills in the conventionally accepted story with attention to more specific, less-known discoveries and individuals, and challenges traditional assumptions about the origins and growth of wireless. This allows for a more comprehensive understanding of how various components and systems evolved. Written in a clear tone with a broad scientific audience in mind, this exciting and thorough treatment is sure to become a classic in the field.

Book Synopsis Extreme Events in Geospace by : Natalia Buzulukova
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 800 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.
