 Free Download Satellite Communications by obert M. Gagliardi English | PDF | 1991 | 591 Pages | ISBN : 9401097623 | 37.2 MB This second edition of Satellite Communications is a revised, updated, and improved version of the first edition (Van Nostrand, 1984) and has been extended to include many newer topics that are rapidly becoming important in modem and next-generation satellite systems. The first half of the book again covers the basics of satellite links, but has been updated to include additional areas such as Global Positioning and deep space satellites, dual polarization, multiple beaming, advanced satellite electronics, frequency synthesizers, and digital frequency generators. The second half of the book is all new, covering frequency and beam hopping, on-board processing, EHF and optical cross links, and mobile satellites and VSAT systems. All of these latter topics figure to be important aspects of satellite systems and space platforms of the twenty-first century. As in the first edition, the objective of the new edition is to present a unified approach to satellite communications, helping the reader to become familiar with the terminology, models, analysis procedures, and evolving design directions for modem and future satellites. The presentation stresses overall system analysis and block diagram design, as opposed to complicated mathematical or physics descriptions. (Backup mathematics is relegated to the appendices where a reader can digest the detail at his own pace. ) The discussion begins with the simplest satellite systems and builds to the more complex payloads presently being used.

Suh; English | 2025 | ISBN: 9798881801151 | 213 pages | True PDF EPUB | 8.15 MB  Free Download SONDERWAFFEN: Experimental Guns, Rockets and Missiles used by the Luftwaffe by Justo Miranda English | October 18, 2024 | ISBN: N/A | ASIN: B0DKB5WZ1Q | 337 pages | EPUB | 67 Mb During the last months of 1942, the balance of military power began to swing in favor of the Allies. The Axis was then forced to change their 'conquer and consolidate' strategy into another of 'defense of metropolitan territory'. The industrial reorganization derived from this sudden change of political objectives proved to be of such magnitude that Germany could only partially comply with it. They made it happen by burying entire factories under armored tunnels, scattering industrial plants to make any enemy bombardment plants more difficult, developing new chemical technologies to compensate for the lack of raw materials, such as rubber and oil, and exploring all possible directions of physics, hoping to find alternative industrial procedures, direction systems, new engineering materials, or the final weapon.  Free Download SOE in Czechoslovakia: The Special Operations Executive's Czech Section in WW2-An Official History English | 2022 | ISBN: 1399082752 | 148 pages | True EPUB | 1.73 MB The majority of the successful SOE operations in Europe took place in countries occupied by the Germans after the outbreak of war in 1939, Hitler's forces being regarded as foreign invaders. In Czechoslovakia it was different. The country, which had large numbers of ethnic Germans living within its borders, had been occupied since 1938, allowing the Germans to establish a strong hold on the country which limited the opportunities for subversive action by resistance movements. Nevertheless, resist the Czechs did, despite the Germans conducting savage and indiscriminate reprisals. It was against this background that SOE attempted to infiltrate its agents into Czechoslovakia in 1941, their role being to help in co-ordinating and expanding the resistance movement and to establish communications with the Czech authorities in the UK. Successful actions were admittedly few before 1942 when one of the most successful SOE-backed operations resulted in the assassination of Reinhard Heydrich, the highest-ranking Nazi to be killed by any resistance group. The huge wave of reprisals against the civilian population which followed severely hampered SOE activities in the immediate aftermath. Another factor which limited SOE's ability to infiltrate Czechoslovakia and to supply the resistance was the distance and difficulty experienced by the RAF in flying to the region. During the short nights of summer, no flights could be attempted. This changed in September 1943 when sorties were able to be conducted from Italy, and by 1944 the scale of operations increased both in frequency and scale. More than 300 Czechs were trained by SOE and, in conjunction with local resistance groups, those that managed to infiltrate back into their homeland, kept the occupying forces constantly on the alert, ensuring that Germany's eastern flank was never entirely secure. This is the first full, official account of SOE in Czechoslovakia, compiled by SOE headquarters staff who had direct access to all the organisation's records, many of which were destroyed after the war.  Free Download Tom Ginsburg, "Rule by Law: The Politics of Courts in Authoritarian Regimes" English | ISBN: 0521895901 | 2008 | 390 pages | PDF | 2 MB Scholars have generally assumed that courts in authoritarian states are pawns of their regimes, upholding the interests of governing elites and frustrating the efforts of their opponents. As a result, nearly all studies in comparative judicial politics have focused on democratic and democratizing countries. This volume brings together leading scholars in comparative judicial politics to consider the causes and consequences of judicial empowerment in authoritarian states. It demonstrates the wide range of governance tasks that courts perform, as well as the way in which courts can serve as critical sites of contention both among the ruling elite and between regimes and their citizens. Drawing on empirical and theoretical insights from every major region of the world, this volume advances our understanding of judicial politics in authoritarian regimes.  Free Download Javier Auyero, "Routine Politics and Violence in Argentina: The Gray Zone of State Power " English | ISBN: 0521872367 | 2007 | 202 pages | PDF | 2 MB Close to three hundred stores and supermarkets were looted during week-long food riots in Argentina in December 2001. Thirty-four people were reported dead and hundreds were injured. Among the looting crowds, activists from the Peronist party (the main political party in the country) were quite prominent. During the lootings, police officers were conspicuously absent - particularly when small stores were sacked. Through a combination of archival research, statistical analysis, multi-sited fieldwork, and taking heed of the perspective of contentious politics, this book provides an analytic description of the origins, course, meanings, and outcomes of the December 2001 wave of lootings in Argentina.
