UNMANNED AERIAL VEHICLES Robotic Air Warfare 1917–2007 - Original PDF
نویسندگان: خلاصه: Unmanned aerial vehicles (UAVs) are the most dynamic field of aerospace technology, and potentially the harbingers of new aviation technology and tactics. They have only emerged from the shadows in recent years, but in fact have been in use for decades. After some limited use in World War II, UAVs began to emerge as a substitute for manned reconnaissance aircraft in the 1950s for missions deemed too dangerous to risk an aircrew. Used in significant numbers in the Vietnam War as well as less-heralded missions such as spy flights over China in the 1950s and 1960s, the contemporary UAV began to emerge in the 1980s. This book examines the development of this unique and mysterious technology, revealing how it has changed combat through the years and speculating on its potential to transform the nature of warfare in the future. Steven J Zaloga examines the pioneering use of UAVs conducted by the Israeli air and the use of UAVs during Operation Desert Storm. Packed with rare, recently declassified photographs and detailed full-color cutaways, this title goes on to investigate the wide deployment of UAVs over Iraq and Afghanistan today, and considers the possible future of the UAV as an actual military weapon.
Saunders Solutions in Veterinary Practice Small Animal Gastroenterology - Original PDF
نویسندگان: خلاصه: Saunders Solutions in Veterinary Practice consists of a series of practical handbooks on selected medical topics on specific veterinary problems. Case-based, this series is aimed at the small animal veterinary practitioner who has qualified less than 10 years and needs quick access to information and wants to increase his/her confidence on handling that range of cases that cover the spectrum that lies between the simple routine first opinion case and the referral. Saunders Solutions in Veterinary Practice provides additional knowledge that leads to improved skills and practice for veterinary practitioners. Not only practitioners, but also veterinary students nearing the end of their course will find this series very useful to brush up their knowledge in a particular area. The volumes are also written with the veterinary nurse in mind with a particular interest in a specific topic, using ‘Nurse Boxes’ in the text to guide them to the specific information they need.
Air Warfare: History, Theory and Practice - Original PDF
نویسندگان: خلاصه: Air Warfare provides an introduction to the subject's theory, history and practice. As well as delivering an up to date look at the strategy, and historiography of air power, Peter Gray explores the theories behind air power and looks at the political, legal and moral dimensions of the application of air power. Topics covered include: - Key military strategists and their legacy - Air power's strategic effects - Leadership, management and command - Tactics, technology and operations The book draws on primary sources including official narratives and published reports, examines key thinkers in the study of air power, and discusses topics such as concepts of warfare as an art or science, cultural perceptions of air power, and the experience of being an airman. With its broad scope and thorough coverage of a range of key topics, Air Warfare takes air power beyond the study of individual campaigns, or controversies, providing a multi-disciplinary approach to air power studies.
Rhetoric and Reality in Air Warfare: The Evolution of British and American Ideas about Strategic Bombing, 1914-1945 (Princeton Studies in International History and Politics) - Original PDF
نویسندگان: خلاصه: A major revision of our understanding of long-range bombing, this book examines how Anglo-American ideas about "strategic" bombing were formed and implemented. It argues that ideas about bombing civilian targets rested on--and gained validity from--widespread but substantially erroneous assumptions about the nature of modern industrial societies and their vulnerability to aerial bombardment. These assumptions were derived from the social and political context of the day and were maintained largely through cognitive error and bias. Tami Davis Biddle explains how air theorists, and those influenced by them, came to believe that strategic bombing would be an especially effective coercive tool and how they responded when their assumptions were challenged.Biddle analyzes how a particular interpretation of the World War I experience, together with airmen's organizational interests, shaped interwar debates about strategic bombing and preserved conceptions of its potentially revolutionary character. This flawed interpretation as well as a failure to anticipate implementation problems were revealed as World War II commenced. By then, the British and Americans had invested heavily in strategic bombing. They saw little choice but to try to solve the problems in real time and make long-range bombing as effective as possible.Combining narrative with analysis, this book presents the first-ever comparative history of British and American strategic bombing from its origins through 1945. In examining the ideas and rhetoric on which strategic bombing depended, it offers critical insights into the validity and robustness of those ideas--not only as they applied to World War II but as they apply to contemporary warfare.
COMBAT PAIR: The Evolution of Air Force-navy Integration in Strike Warfare - Original PDF
نویسندگان: خلاصه: This report documents the exceptional cross-service harmony that the U.S. Air Force and U.S. Navy have steadily developed in their conduct of integrated strike operations since the first Persian Gulf War in 1991. That close harmony contrasts sharply with the situation that prevailed throughout most of the Cold War, when the two services maintained separate and unique operating mindsets and lacked any significant interoperability features.
Medieval music and the art of memory - Original PDF
نویسندگان: خلاصه: This bold challenge to conventional notions about medieval music disputes the assumption of pure literacy and replaces it with a more complex picture of a world in which literacy and orality interacted. Asking such fundamental questions as how singers managed to memorize such an enormous amount of music and how music composed in the mind rather than in writing affected musical style, Anna Maria Busse Berger explores the impact of the art of memory on the composition and transmission of medieval music. Her fresh, innovative study shows that although writing allowed composers to work out pieces in the mind, it did not make memorization redundant but allowed for new ways to commit material to memory. Since some of the polyphonic music from the twelfth century and later was written down, scholars have long assumed that it was all composed and transmitted in written form. Our understanding of medieval music has been profoundly shaped by German philologists from the beginning of the last century who approached medieval music as if it were no different from music of the nineteenth century. But Medieval Music and the Art of Memory deftly demonstrates that the fact that a piece was written down does not necessarily mean that it was conceived and transmitted in writing. Busse Berger's new model, one that emphasizes the interplay of literate and oral composition and transmission, deepens and enriches current understandings of medieval music and opens the field for fresh interpretations.
The Music of the Big Bang: The Cosmic Microwave Background and the New Cosmology (2008)(en)(160s) - Original PDF
نویسندگان: خلاصه: The cosmic microwave background radiation is the afterglow of the big bang: a tenuous signal, more than 13 billion years old, which carries the answers to many of the questions about the nature of our Universe. It was serendipitously discovered in 1964, and thoroughly investigated in the last four decades by a large number of experiments. Two Nobel Prizes in Physics have already been awarded for research on the cosmic background radiation: one in 1978 to Arno Penzias and Robert Wilson, who first discovered it, the other in 2006, to George Smoot and John Mather, for the results of the COBE satellite. Most cosmological information is encoded in the cosmic background radiation by acoustic oscillations in the dense plasma that filled the primordial Universe: a "music" of the big bang, which cosmologists have long been trying to reconstruct and analyze, in order to distinguish different cosmological models, much like one can distinguish different musical instruments by their timbre and overtones. Only lately, has this amazing cosmic sound been unveiled by such experiments as BOOMERANG and MAXIMA and, more recently, by the WMAP satellite. This led to a giant leap in our understanding of the Universe, but the investigation is not over yet. The book focuses on how the exploration of the cosmic background radiation has shaped our picture of the Universe, leading even the non-specialized readers towards the frontier of cosmological research, helping them to understand, using a simple language and captivating metaphors, the mechanisms behind the Universe in which we live.
Sound tracks: Popular Music,Identity and Place - Original PDF
نویسندگان: خلاصه: Soundtracks traces the relationships between music, space and identity-from inner city 'scenes' to the music of nations-to give a wide-ranging perspective on popular music. It examines the influence of cultures, economics, politics and technology on the changing structure and geographies of music at local and global levels. Taking music from its role as an expression of local culture in indigenous societies to its gradual evolution towards a global music industry, this work pays particular attention to the complex spread of world music from reggae to zouk and beyond. Containing an impressive and comprehensive range of global case studies Soundtracks takes an innovative approach to the complex and changing relationships between music and space to provide a genuine global assessment of the power and pleasure of popular music in its many forms.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
