Available in PDF, EPUB and Kindle. Book excerpt: 'Galactic Radio Astronomy' was chosen as the subject of this Symposium, which was held in conjunction with the IAU General Assembly that took place in Sydney in August 1973, largely because it is a very suitable Southern Hemisphere topic. This results in part from the advantages of a southern location in studying the Galaxy and in part from the long association of Australia with radio astronomy. Following the General Assembly, the Symposium was held at the Surf air Inter national Hotel in Maroochydore, Queensland, from 3 to 7 September, 1973. The conference participants were effectively isolated from the rest of the world during the Symposium, and the excellent spring weather and geographical situation led to the development of an unusually good rapport. The Symposium was sponsored by Commissions 40, 33, and 34. The Organizing Committee was composed of A. H. Barrett (chairman), J. E. Baldwin, D. S. Heeschen, F. J. Kerr, J. Lequeux, S. W. McCuskey, P. G. Mezger, B. Y. Mills, Yu. N. Parijskij, B. J. Robinson, H. van der Laan, and H. F. Weaver. The Local Committee, consisting ofB. J. Robinson, N. G. Seddon, and P. J. Kelly, looked after the arrangements in very fine style. The Symposium was supported financially by the IAU, the Australian Academy o~ Science, the CSIRO Division of Radiophysics, Union Carbide Australia Limited, and the Science Foundation for Physics within the University of Sydney.

Download or read book The Emergence of Astrophysics in Asia written by Tsuko Nakamura and published by Springer. This book was released on 2018-06-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the ways in which attitudes toward astronomy in Australia, China, India, Indonesia, Japan, South Korea, New Zealand, Taiwan, Thailand and Uzbekistan have changed with the times. The emergence of astrophysics was a worldwide phenomenon during the late nineteenth and early twentieth centuries, and it gradually replaced the older-style positional astronomy, which focused on locating and measuring the movements of the planets, stars, etc.. Here you will find national overviews that are at times followed by case studies of individual notable achievements. Although the emphasis is on the developments that occurred around 1900, later pioneering efforts in Australian, Chinese, Indian and Japanese radio astronomy are also included. As the first book ever published on the early development of astrophysics in Asia, the authors fill a chronological and technological void. Though others have already written about earlier astronomical developments in Asia, and about the recent history of astronomy in various Asian nations, no one has examined the emergence of astrophysics, the so-called ‘new astronomy’ in Asia during the late nineteenth and early twentieth centuries.

Available in PDF, EPUB and Kindle. Book excerpt: For over 35 years, radio astronomical techniques have made an impressive series of advances in our understanding of solar phenomena. However, although the subject has been partially discussed in "Paris Symposium on Radio Astronomy" in 1958, NASA-GSFC Symposium on "Physics of Solar Flares" in 1963, and the lAU Symposium No. 57 on "Coronal Disturbances" in 1973, there has not been a major international meeting dedicated to "Radio Physics of the Sun". This is the first major symposium on the subject held under the auspices of the International Astronomical Union. It was jointly spon sored by lAU Commission 40, Radio Astronomy, and by lAU Commission 10, Solar Activity. It was also sponsored by the Solar Physics Division of the American Astronomical Society. Thig volume contains the proceedings of this meeting, lAU Symposium No. 86 on "Radio Physics of the Sun" that was held in College Park, Maryland, August 7-10, 1979. The Scientific Organizing Committee of the Symposium consisted of M. R. Kundu (chairman), G. A. Dulk, O. Hachenberg, M. Kuperus, D. J. McLean, D. Melrose, M. Pick, J. L. Steinberg, T. Takakura, A. Tlamicha and V. V. Zheleznyakov. The topics and speakers were chosen in order to emphasize the current observational material with particular reference to centi meter wavelength observations of a few arc-second resolution, fast two-dimensional pictures of the sun at meter-decameter wavelengths and the recent advances in plasma and radiation theory.

Download or read book Chromospheric Fine Structure written by R.G. Athay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The devotion of an IA U symposium entirely to the topic of chromo spheric fine structure at a time when models of the spherically symmetric chromosphere are still evolving constitutes a valid recognition of the growing feeling among solar astron omers that the chromosphere cannot be understood independently of its discrete structural features. Network structure, which seemingly borders the photospheric supergranule cells, persists intact throughout the chromosphere and most of the chromosphere-corona transition region. The network is the locus of the bright coarse mottles, and the spicule bushes and is the terminus for one end of the quiet chromo spheric fibrils as well. Additionally, it is the locus of most of the magnetic flux of the quiet chromosphere. It is not surprising, therefore, that current studies of the chromosphere tend to center around efforts to better describe the network phenom ena and to ascertain the physical properties of the network features. Clearly, the supergranule cells and associated network structures constitute a fundamental and singularly important feature of solar structure in the boundary layers. Just as it is now clear that much of the chromo spheric fine structure is associated with the network bordering supergranule cells, it seems equally clear that structural features are almost universally associated with both fluid flow and magnetic geometry. Indeed, many observers claim that the brightness features faithfully map the mag netic lines offorce while still others claim that associated with each class of brightness feature there is a more or less unique fluid flow.
Download or read book Advances in Broadband Communication and Networks written by Johnson I. Agbinya and published by CRC Press. This book was released on 2022-09-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Broadband communications has become the major focus for industry for offering rich multimedia IP services in next generation networks. This book deals with the state-of-the-art and the underlying principles of key technologies which facilitate broadband telecommunications including millimetre wave gigabit Ethernet, terahertz communication, multiple input multiple output (MIMO) technology, orthogonal frequency division multiplex (OFDM), ultra wideband (UWB) and the fourth generation (4G) network technologies. The book illustrates the use of these technologies, including high resolution three-dimensional millimetre wave radar imaging and terahertz imaging techniques. Within the next few years advances in graphic rendering and the application of millimetre wave radar technology will enable high resolution radar surveillance and operators of industrial processes to control their machines and to navigate remotely even in poor visibility environments. The principles and performance of terahertz imaging are also demonstrated in this important book. The performance and success of emerging all-IP networks depend largely on the efficiency of broadband technologies and this book provides the basis for 4G networks and explores key performance measures such as quality of service and handover between distributed networks (mobile and fixed). The book also demonstrates the medical and biomedical applications of broadband wireless communications.
Download or read book Corporate Ties That Bind written by Martin J. Walker and published by Skyhorse. This book was released on 2017-03-28 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 21st century, corporations have worked their way into government and, as they become increasingly more powerful, arguments about their involvement with public health have become increasingly black and white. With corporations at the center of public health and environmental issues, everything chemical or technological is good, everything natural is bad; scientists who are funded by corporations are right and those who are independent are invariably wrong. There is diminishing common ground between the two opposed sides in these arguments. Corporate Ties that Bind is a collection of essays written by influential academic scholars, activists, and epidemiologists from around the world that scrutinize the corporate reasoning, false science and trickery involving those, like in-house epidemiologists, who mediate the scientific message of organizations who attack and censure independent voices. This book addresses how the growth of corporatism is destroying liberal democracy and personal choice. Whether addressing asbestos, radiation, PCBs, or vaccine regulation, the essays here address the dangers of trusting corporations and uncover the lengths to which corporations put profits before health.
Download or read book Joe Pawsey and the Founding of Australian Radio Astronomy written by W. M. Goss and published by Springer Nature. This book was released on 2023-01-10 with total page 838 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is a biography of Joseph L. Pawsey. It examines not only his life but the birth and growth of the field of radio astronomy and the state of science itself in twentieth century Australia. The book explains how an isolated continent with limited resources grew to be one of the leaders in the study of radio astronomy and the design of instruments to do so. Pawsey made a name for himself in the international astronomy community within a decade after WWII and coined the term radio astronomy. His most valuable talent was his ability to recruit and support bright young scientists who became the technical and methodological innovators of the era, building new telescopes from the Mills Cross and Chris (Christiansen) Cross to the Parkes radio telescope. The development of aperture synthesis and the controversy surrounding the cosmological interpretation of the first major survey which resulted in the Sydney research group's disagreements with Nobel laureate Martin Ryle play major roles in this story. This book also shows the connections among prominent astronomers like Oort, Minkowski, Baade, Struve, famous scientists in the UK such as J.A. Ratcliffe, Edward Appleton and Henry Tizard, and the engineers and physicists in Australia who helped develop the field of radio astronomy. Pawsey was appointed the second Director of the National Radio Astronomy Observatory (Green Bank, West Virginia) in October 1961; he died in Sydney at the age of 54 in late November 1962. Upper level students, scientists and historians of astronomy and technology will find the information, much of it from primary sources, relevant to any study of Joseph L. Pawsey or radio astronomy. This open access book includes a Foreword by Woodruff T. Sullivan II.

Download or read book Golden Years of Australian Radio Astronomy written by Wayne Orchiston and published by Springer Nature. This book was released on 2022-01-20 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of Australian radio astronomy from 1945 to 1960 has been studied in detail by numerous historians of science in recent years. This Open Access book is the first to present an overview of this remarkable chapter in Australian science. The book begins in the post-war period, as the Radiophysics Laboratory in Sydney switched from secret wartime research on radar to peacetime applications of this new technology. Next follows the detection of radio waves from space and the ensuing transformation of this fledgling science into the dominant research program at the Radiophysics Lab. Drawing from this history, the book shows how by 1960 the Radiophysics Lab had become the largest and most successful radio astronomy group in the world. The final chapter presents an overview of Australian radio astronomy from 1960 to the present day, as Australia prepares to co-host the multi-national, multi-billion-dollar Square Kilometre Array. Nearly 300 high-quality images complement the text, drawn from a wide range of sources including the extensive collection held by the CSIRO Radio Astronomy Image Archive. The book will be an essential reference for readers interested in the scientific and cultural development of radio astronomy. This book is published open access under a CC BY 4.0 license.

Download or read book Literature 1974 Part 1 written by S. Böhme and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume II contains literature published in 1974 and received before August IS, 1974; some older literature which was received late and which is not recorded in earlier volumes is also included. Begin ning with this volume some minor changes of our classification scheme have been made. We acknowledge with thanks contributions to this volume by Dr. J. BouSka, who surveyed journals and publications in the Czech language and supplied us with abstracts in English, and by the Common wealth Scientific and Industrial Research Organization (C.S.I.R.O.), Sydney, for providing titles and abstracts of papers on radio astronomy.
