This book was released on 2004 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le domaine spatial, la diversité de polarisation est encore une ressource rare. Les radars spatiaux opérationnels civils actuels, ERS et RADARSAT n'offrent pas cette diversité de polarisation. Leurs émissions et réceptions sont respectivement limitées aux polarisations verticale et horizontale. L'arrivée d'ENVISAT, sans ouvrir la porte à la polarimétrie totale, offre tout de même des perspectives d'utilisation de signatures radar acquises sous différentes configurations de polarisation. Par ailleurs, les missions spatiales de demain (RadarSat2, ALOS, ...) emportent toutes des modes de polarimétrie totale expérimentaux (notée fp pour full polarimetry). La technique polarimétrique spatiale est par conséquent une technique de devenir, pour laquelle les potentialités doivent être précisemment évaluées. Néanmoins, la spécificité des missions spatiales réside dans le fait qu'elles sont par nature moins performantes en termes de résolution géométrique, de bilan de liaison que leurs homologues aéroportés. L'objectif principal de cette étude est de mettre en lumière les possibles compromis à établir entre la réduction de la mesure polarimétrique, et les gains en terme d'architecture des charges utiles radar qui en découlent. On évalue successivement des architectures incohérentes basées sur la réception incohérente de signaux de co- et de cross-polarisation, puis des architectures cohérentes qui se cantonnent à des mesures de co-polarisation. On introduit un mode de visualisation original de la mesure polarimétrique permettant de n'en retenir que le caractère utile (la représentation ITS) [...]

Download or read book The Palgrave Encyclopedia of Imperialism and Anti Imperialism written by Immanuel Ness and published by Palgrave Macmillan. This book was released on 2021-01-13 with total page 2931 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in its second edition, The Palgrave Encyclopedia of Imperialism and Anti-Imperialism is the definitive reference work for students and scholars interested in the theory and history of imperialism and anti-imperialism from the sixteenth century to the present day. Written by an international and interdisciplinary group of scholars, it provides detailed studies of imperialism’s roots, goals, methods and impact around the world. It also explores the rich and varied tradition of anti-imperialism, focusing on its most significant leaders, intellectuals, theories and social movements. The second edition has been expanded to include a number of topics not covered in the first edition, such as feminism, the environment, crime, international law, imperialism and anti-imperialism in art, literature and poetry, and medicine. In addition, existing entries have been updated and revised to reflect the latest scholarship. Offering a more comprehensive and thorough treatment of imperialism and anti-imperialism, the second edition of this encyclopedia takes a comparative, global approach to challenge and enhance our understanding of today’s world.

Download or read book Women in Combat written by Congressional Research Service and published by Createspace Independent Publishing Platform. This book was released on 2017-01-09 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades of conflict, women have served with valor and continue to serve on combat aircraft, naval vessels, and in support of ground combat operations. The expansion of roles for women in the Armed Forces has evolved since the early days of the military when women were restricted by law and policy from serving in certain occupations and units. Women have not been precluded by law from serving in any military unit or occupational specialty since 1993 when Congress repealed the remaining prohibitions on women serving on combatant aircraft and vessels. However, Department of Defense (DOD) policies have prevented women from being assigned to units below brigade level where the unit's primary mission was to engage directly in ground combat. This policy barred women from serving in infantry, artillery, armor, combat engineers, and special operations units of battalion size or smaller. On January 24, 2013, then-Secretary of Defense Leon Panetta rescinded the rule that restricted women from serving in combat units and directed the military departments and services to review their occupational standards and assignment policies and to make recommendations for opening all combat roles to women no later than January 1, 2016. On December 3, 2015, Secretary of Defense Ashton Carter ordered the military to open all combat jobs to women with no exceptions. This most recent policy change followed extensive studies that were completed by the military departments and by the Special Operations Command (SOCOM) on issues such as unit cohesion, women's health, equipment, facilities modifications, propensity to serve, and international experiences with women in combat. These studies also included a review and validation of gender-neutral occupational standards for combat roles where such standards existed. On March 10, 2016, Secretary Carter announced that the Services' and SOCOM's implementation plans for the integration of women into direct ground combat roles were approved. Some concerns about the implementation of the new policy remain, including the recruitment, assignment, and career management of women into the new roles, and the impact of integration on unit readiness. Congress has oversight authority in these matters, and may also consider issues such as equal opportunity, equal responsibility (such as selective service registration), and the overall manpower needs of the military.
