This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les travaux de recherche de cette thèse s'inscrivent dans le cadre de la sécurité par chaos des réseaux locaux sans fil, en particulier les réseaux de capteurs sans fil. L'originalité de cette thèse consiste à proposer des cryptosystèmes à base de chaos plus adaptés aux réseaux de capteurs, en termes de consommation d'énergie, que les algorithmes conventionnels et à réaliser une implémentation sur une plateforme réelle. Nous présentons en premier lieu un état de l'art des réseaux, les menaces, les contraintes limitant le processus de sécurité des informations ainsi que les principales techniques de cryptographie. Nous donnons un aperçu sur la théorie de chaos et nous validons l'aspect aléatoire de plusieurs suites chaotiques par les tests statistiques du NIST. Nous proposons ensuite des nouvelles méthodes de construction de S-Box chaotiques tout en prouvant leur robustesse contre les attaques traditionnelles. Nous proposons enfin un nouvel algorithme de cryptage d'image dédié au réseau de capteurs sans fil. La validation de nos contributions est effectuée par simulation et par des mesures expérimentales sur une plateforme de réseaux de capteurs réels (SensLab).

Download or read book Global Burden of Disease and Risk Factors written by Alan D. Lopez and published by World Bank Publications. This book was released on 2006-04-02 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strategic health planning, the cornerstone of initiatives designed to achieve health improvement goals around the world, requires an understanding of the comparative burden of diseases and injuries, their corresponding risk factors and the likely effects of invervention options. The Global Burden of Disease framework, originally published in 1990, has been widely adopted as the preferred method for health accounting and has become the standard to guide the setting of health research priorities. This publication sets out an updated assessment of the situation, with an analysis of trends observed since 1990 and a chapter on the sensitivity of GBD estimates to various sources of uncertainty in methods and data.

Download or read book A Civil Society written by James Smith Allen and published by . This book was released on 2022-05 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Civil Society explores the struggle to initiate women as full participants in the masonic brotherhood that shared in the rise of France's civil society and its "civic morality" on behalf of women's rights. As a vital component of the third sector during France's modernization, freemasonry empowered women in complex social networks, contributing to a more liberal republic, a more open society, and a more engaged public culture. James Smith Allen shows that although women initially met with stiff resistance, their induction into the brotherhood was a significant step in the development of French civil society and its "civic morality," including the promotion of women's rights in the late nineteenth century. Pulling together the many gendered facets of masonry, Allen draws from periodicals, memoirs, and archival material to account for the rise of women within the masonic brotherhood in the context of rapid historical change. Thanks to women's social networks and their attendant social capital, masonry came to play a leading role in French civil society and the rethinking of gender relations in the public sphere.
Download or read book The Sense of Decadence in Nineteenth Century France written by Koenraad W. Swart and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: "It was the best oftimes. It was the worst oftimes. " The famous open ing sentence ofCharles Dickens' Tale oJ Two Cities can serve as a motto to characterize the mixture of optimism and pessimism with which a large number of nineteenth-century intellectuals viewed the con dition of their age. It is nowadays hardly necessary to accentuate the optimistic elements in the nineteenth-century view of history; many recent historians have sharply contrasted the complacency and the great expectations of the past century with the fears and anxieties rampant in our own age. It is often too readily assumed that a hundred years ago all leading thinkers as weil as the educated public were addicted to the cult of progress and ignored or minimized those trends of their times that paved the way for the catastrophes of the twentieth century. In the nineteenth century the intoxicating triumphs of modern science undeniably induced the general public to believe that pro gress was not an accident but a necessity and that evil and immo rality would gradually disappear. Yet fears, misgivings, and anxieties were not as exceptional in the nineteenth century as is often imagined. Such feelings were not restricted to a few dissenting philosophers and poets like Schopenhauer, Kierkegaard, 'Dostoevsky, Baudelaire, and Nietzsche.

Download or read book Accounting for Culture written by Caroline Andrew and published by University of Ottawa Press. This book was released on 2005-03-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many scholars, practitioners, and policy-makers in the cultural sector argue that Canadian cultural policy is at a crossroads: that the environment for cultural policy-making has evolved substantially and that traditional rationales for state intervention no longer apply. The concept of cultural citizenship is a relative newcomer to the cultural policy landscape, and offers a potentially compelling alternative rationale for government intervention in the cultural sector. Likewise, the articulation and use of cultural indicators and of governance concepts are also new arrivals, emerging as potentially powerful tools for policy and program development. Accounting for Culture is a unique collection of essays from leading Canadian and international scholars that critically examines cultural citizenship, cultural indicators, and governance in the context of evolving cultural practices and cultural policy-making. It will be of great interest to scholars of cultural policy, communications, cultural studies, and public administration alike.

Download or read book Geographies of Disorientation written by Marcella Schmidt di Friedberg and published by Routledge. This book was released on 2017-08-10 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial disorientation is of key relevance to our globalized world, eliciting complex questions about our relationship with technology and the last remaining vestiges of our animal nature. Viewed more broadly, disorientation is a profoundly geographical theme that concerns our relationship with space, places, the body, emotions, and time, as well as being a powerful and frequently recurring metaphor in art, philosophy, and literature. Using multiple perspectives, lenses, methodological tools, and scales, Geographies of Disorientation addresses questions such as: How do we orient ourselves? What are the cognitive and cultural instruments that we use to move through space? Why do we get lost? Two main threads run through the book: getting lost as a practice, explored within a post-phenomenological framework in relation to direct and indirect observation, wayfinding performances, and the various methods and tools used to find our position in space; and disorientation as a metaphor for the contemporary era, used in a broad range of contexts to express the difficulty of finding points of reference in the world we live in. Drawing on a wide range of literature, Geographies of Disorientation is a highly original and intruiging read which will be of interest to scholars of human geography, philosophy, sociology, anthropology, cognitive science, information technology, and the communication sciences.
Download or read book The Practical Guide to Humanitarian Law written by Françoise Bouchet-Saulnier and published by Rowman & Littlefield Publishers. This book was released on 2013-12-12 with total page 827 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in a comprehensively updated edition, this indispensable handbook analyzes how international humanitarian law has evolved in the face of these many new challenges. Central concerns include the war on terror, new forms of armed conflict and humanitarian action, the emergence of international criminal justice, and the reshaping of fundamental rules and consensus in a multipolar world. ThePractical Guide to Humanitarian Law provides the precise meaning and content for over 200 terms such as terrorism, refugee, genocide, armed conflict, protection, peacekeeping, torture, and private military companies—words that the media has introduced into everyday conversation, yet whose legal and political meanings are often obscure. The Guide definitively explains the terms, concepts, and rules of humanitarian law in accessible and reader-friendly alphabetical entries. Written from the perspective of victims and those who provide assistance to them, the Guide outlines the dangers, spells out the law, and points the way toward dealing with violations of the law. Entries are complemented by analysis of the decisions of relevant courts; detailed bibliographic references; addresses, phone numbers, and Internet links to the organizations presented; a thematic index; and an up-to-date list of the status of ratification of more than thirty international conventions and treaties concerning humanitarian law, human rights, refugee law, and international criminal law. This unprecedented work is an invaluable reference for policy makers and opinion leaders, students, relief workers, and members of humanitarian organizations. Published in cooperation with Doctors Without Borders/Médecins Sans Frontières.

Download or read book The Challenge for Africa written by Wangari Maathai and published by Anchor. This book was released on 2009-04-07 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this groundbreaking work, the Nobel Peace Prize-winner and founder of the Green Belt Movement offers a new perspective on the troubles facing Africa today. Too often these challenges are portrayed by the media in extreme terms connoting poverty, dependence, and desperation. Wangari Maathai, the author of Unbowed, sees things differently, and here she argues for a moral revolution among Africans themselves. Illuminating the complex and dynamic nature of the continent, Maathai offers “hardheaded hope” and “realistic options” for change and improvement. She deftly describes what Africans can and need to do for themselves, stressing all the while responsibility and accountability. Impassioned and empathetic, The Challenge for Africa is a book of immense importance.
