Download or read book An Army Like No Other written by Haim Bresheeth-Zabner and published by Verso Books. This book was released on 2020-08-25 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of the IDF that argues that Israel is a nation formed by its army. The Israeli army, officially named the Israel Defence Forces (IDF), was established in 1948 by David Ben-Gurion, Israel's first prime minister, who believed that 'the whole nation is the army'. In his mind, the IDF was to be an army like no other. It was the instrument that might transform a diverse population into a new people. Since the foundation of Israel, therefore, the IDF has been the largest, richest and most influential institution in Israel's Jewish society and is the nursery of its social, economic and political ruling class. In this fascinating history, Bresheeth charts the evolution of the IDF from the Nakba to the continued assaults upon Gaza, and shows that the state of Israel has been formed out of its wars. He also gives an account of his own experiences as a young conscript during the 1967 war. He argues that the army is embedded in all aspects of daily life and identity. And that we should not merely see it as a fighting force enjoying an international reputation, but as the central ideological, political and financial institution of Israeli society. As a consequence, we have to reconsider our assumptions on what any kind of peace might look like.
Download or read book Antenna Measurements at Super high Frequencies written by Iurii Vasil'evich Shubarin and published by . This book was released on 1966 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first chapter there is given a basis and account of the method of measurement of basic parameters of shf antennas, typical circuits applied here and also methods of processing and estimating error of measurements. In the second chapter seven laboratory projects of antenna practical work are described. The practical work permits us to subject to graphic experimental proof a series of very important theoretical propositions expounded in the course on shf antennas; to illustrate the method of measurements of parameters of antennas with practical examples; to acquaint students with the design and certain methods of engineering calculation of basic types of shf antennas. Description of every practical project contains information on designing the proper laboratory installation, assignment for conducting experiments and calculations, and also a list of materials which should be presented in the report on the finished project. Selection of problems for practical work and the character of assignments are aimed at development in students of a desire for independent investigation. Everywhere where possible, comparison of theory with experiment and estimation of its accuracy are required. In the third chapter there is given a description of a series of samples of typical equipment applied during shf antenna measurements. This facilitates home preparation of students for doing assignments of antenna practical work and can serve as a brief reference book on frequently used equipment. (Author).

Download or read book Compact Slot Array Antennas for Wireless Communications written by Alan J. Sangster and published by Springer. This book was released on 2018-11-11 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes and provides design guidelines for antennas that achieve compactness by using the slot radiator as the fundamental building block within a periodic array, rather than a phased array. It provides the basic electromagnetic tools required to design and analyse these novel antennas, with sample calculations where relevant. The book presents a focused introduction and valuable insights into the relevant antenna technology, together with an overview of the main directions in the evolving technology of compact planar arrays. While the book discusses the historical evolution of compact array antennas, its main focus is on summarising the extensive body of literature on compact antennas. With regard to the now ubiquitous slot radiator, it seeks to demonstrate how, despite significant antenna size reductions that at times even seem to defy the laws of physics, desirable radiation pattern properties can be preserved. This is supported by an examination of recent advances in frequency selective surfaces and in metamaterials, which can, if handled correctly, be used to facilitate physics-defying designs. The book offers a valuable source of information for communication systems and antenna design engineers, especially thanks to its overview of trends in compact planar arrays, yet will also be of interest to students and researchers, as it provides a focused introduction and insights into this highly relevant antenna technology.

Download or read book Introduction to Smart Antennas written by Constantine A. Balanis and published by Morgan & Claypool Publishers. This book was released on 2007 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the growing demand for mobile communications is constantly increasing, the need for better coverage, improved capacity, and higher transmission quality rises. Thus, a more efficient use of the radio spectrum is required. Smart antenna systems are capable of efficiently utilizing the radio spectrum and is a promise for an effective solution to the present wireless systems' problems while achieving reliable and robust high-speed high-data-rate transmission. The purpose of this book is to provide the reader a broad view of the system aspects of smart antennas. In fact, smart antenna systems comprise several critical areas such as individual antenna array design, signal processing algorithms, space-time processing, wireless channel modeling and coding, and network performance. In this book we include an overview of smart antenna concepts, introduce some of the areas that impact smart antennas, and examine the influence of interaction and integration of these areas to Mobile Ad-Hoc Networks. In addition, the general principles and major benefits of using space-time processing are introduced, especially employing multiple-input multiple-output (MIMO) techniques.
Download or read book A Selection of Modern Italian Poetry in Translation written by Roberta L. Payne and published by McGill-Queen's Press - MQUP. This book was released on 2004 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: What was Italian poetry like in the years of extraordinary historical, intellectual, aesthetic, and spiritual change between the 1860s and the Unification of Italy in the 1960s? In A Selection of Modern Italian Poetry in Translation Roberta Payne provides a bilingual collection of ninety-two poems by thirty-five Italian poets, including works of classicism and passionate decadentism, examples of crepuscularism, and poetry by Ungaretti, Montale, and Quasimodo. Payne pays particular attention to poets of the fifties and sixties, futurists, and female poets. She notes that the futurists, who have rarely been translated, were particularly important as they were truly original, attempting to develop new notions of word, line, sound, and phrase. Such new notions make translating them particularly challenging. She also offers a large sampling from poets of the fifties and sixties, many of whom have won the Viareggio Prize. Poems by women in this volume reflect diverse schools and directions while maintaining a distinctly female voice. Containing the original Italian and the translation side-by-side, this volume offers a wonderful introduction to Italian poetry to scholars and general readers alike.
