This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux mesh sans fil (Wireless Mesh Networks-WMNs) sont des réseaux facilement déployables et à faible coût qui peuvent étendre l'Internet dans des zones où les autres réseaux peuvent difficilement accéder. Cependant, plusieurs problèmes de qualité de service (QoS) et de sécurité freinent le déploiement à grande échelle des WMNs. Dans cette thèse, nous proposons un modèle de contrôle d'admission (CA) et un système de réputation afin d'améliorer les performances du réseau mesh et de le protéger des nœuds malveillants. Notre système de CA vise à assurer la QoS des flux admis dans le réseau en termes de bande passante et de délai tout en maximisant l'utilisation de la capacité du canal. L'idée de notre solution est d'associer au contrôle d'admission une planification de liens afin d'augmenter la bande passante disponible. Nous proposons également un système de réputation ayant pour but de détecter les nœuds malveillants et de limiter les fausses alertes induites par la perte de paquets sur les liens du réseau. L'idée de notre solution est d'utiliser des tests statistiques comparant la perte de paquets sur les liens avec un modèle de perte préétabli. De plus, il comprend un système de surveillance composé de plusieurs modules lui permettant détecter un grand nombre d'attaques. Notre CA et notre système de réputation ont été validés, les résultats montrent qu'ils atteignent tous deux leurs objectifs.

Download or read book The Violence of Modernity written by Debarati Sanyal and published by JHU Press. This book was released on 2020-03-03 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Violence of Modernity turns to Charles Baudelaire, one of the most canonical figures of literary modernism, in order to reclaim an aesthetic legacy for ethical inquiry and historical critique. Works of modern literature are commonly theorized as symptomatic responses to the trauma of history. In a climate that tends to privilege crisis over critique, Debarati Sanyal argues that it is urgent to rethink literary experience in terms that recall its contestatory potential. Examining Baudelaire's poems afresh, she shifts the focus of critical attention toward an account of modernism as an active engagement with violence, specifically the violence of history in nineteenth-century France. Sanyal analyzes a literary current that uses the traditional hallmarks of modernism—irony, intertextuality, self-reflexivity, and formalism—to challenge the historical violence of modernity. Baudelaire and the committed ironists writing in his wake teach us how to read and resist the violence of history, and thereby to challenge the melancholy tenor of our contemporary "wound culture." In a series of provocative readings, Sanyal presents Baudelaire's poetry as an aesthetic form that contests historical violence through rhetorical strategies of complicity, counterviolence, and critique. The book develops a new account of Baudelaire's significance as a modernist by dislodging him both from his traditional status as a practitioner of "art for art's sake" and from his more recent incarnation as the poet of trauma. Following her extended analysis of Baudelaire's poetry, Sanyal in later chapters considers a number of authors influenced by his strategies—including Rachilde, Virginie Despentes, Albert Camus, and Jean-Paul Sartre—to examine the relevance of their interventions for our current climate of trauma and terror. The result is a study that underscores how Baudelaire's legacy continues to energize literary engagements with the violence of modernity.
Download or read book The Originality of the Avant Garde and Other Modernist Myths written by Rosalind E. Krauss and published by MIT Press. This book was released on 1986-07-09 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-founder and co-editor of October magazine, a veteran of Artforum of the 1960s and early 1970s, Rosalind Krauss has presided over and shared in the major formulation of the theory of postmodernism. In this challenging collection of fifteen essays, most of which originally appeared in October, she explores the ways in which the break in style that produced postmodernism has forced a change in our various understandings of twentieth-century art, beginning with the almost mythic idea of the avant-garde. Krauss uses the analytical tools of semiology, structuralism, and poststructuralism to reveal new meanings in the visual arts and to critique the way other prominent practitioners of art and literary history write about art. In two sections, "Modernist Myths" and "Toward Postmodernism," her essays range from the problem of the grid in painting and the unity of Giacometti's sculpture to the works of Jackson Pollock, Sol Lewitt, and Richard Serra, and observations about major trends in contemporary literary criticism.

Download or read book The Tree and the Canoe written by Joël Bonnemaison and published by University of Hawaii Press. This book was released on 1994-01-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This personal observation of Tanna, an island in the southern part of the Vanuatu archipelago, presents an extraordinary case study of cultural resistance. Based on interviews, myths and stories collected in the field, and archival research, The Tree and the Canoe analyzes the resilience of the people of Tanna, who, when faced with an intense form of cultural contact that threatened to engulf them, liberated themselves by re-creating, and sometimes reinventing, their own kastom. Following a lengthy history of Tanna from European contact, the author discusses in detail original creation myths and how Tanna people revived them in response to changes brought by missionaries and foreign governments. The final chapters of the book deal with the violent opposition of part of the island population to the newly established National Unity government.
Download or read book Conscripts and Deserters written by Alan I. Forrest and published by Oxford University Press, USA. This book was released on 1989 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between the outbreak of war with Austria in 1792 and Napoleon's final debacle in 1814, France remained almost continously at war, recruiting in the process some two to three million frenchmen--a level of recruitment unknown to previous generations and widely resented as an attack on the liberties of rural communities. Forrest challenges the notion of a nation heroically rushing to arms by examining the massive rates of desertion and avoidance of service as well as their consequences on French society--on military campaigns and the morale of armies, on political opinion at home, on the social fabric of local villages, and on the Napoleonic dream of bringing about a coherent and centralized state.
Download or read book Bourdieu and Literature written by John R. W. Speller and published by Open Book Publishers. This book was released on 2011 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bourdieu and Literature is a wide-ranging, rigorous and accessible introduction to the relationship between Pierre Bourdieu's work and literary studies. It provides a comprehensive overview and critical assessment of his contributions to literary theory and his thinking about authors and literary works. One of the foremost French intellectuals of the post-war era, Bourdieu has become a standard point of reference in the fields of anthropology, linguistics, art history, cultural studies, politics, and sociology, but his longstanding interest in literature has often been overlooked. This study explores the impact of literature on Bourdieu's intellectual itinerary, and how his literary understanding intersected with his sociological theory and thinking about cultural policy. This is the first full-length study of Bourdieu's work on literature in English, and it provides an invaluable resource for students and scholars of literary studies, cultural theory and sociology.

Download or read book H N i a Metropolis in the Making written by Collectif and published by IRD Éditions. This book was released on 2018-11-19 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Built on 'the bend in the Red River', Hà Nội is among Southeast Asia's most ancient capitals. Over the centuries, it took shape in part from a dense substratum of villages. With the economic liberalisation of the 1980s, it encountered several obstacles to its expansion: absence of a real land market, high population densities, the government's food self-suffciency policy that limits expropriations of land and the water management constraints of this very vulnerable delta. Since the beginning of the new millennium, the change in speed brought about by the state and by property developers in the construction and urban planning of the province-capital poses the problem of integration of in situ urbanised villages, the importance of preserving a green belt around Hà Nội and the necessity of protection from flooding. The harmonious fusion of city and countryside, which has always constituted the Red River Delta's defining feature, appears to be in jeopardy. Working from a rich body of maps and field studies, this collective work reveals how this grass-roots urbanisation encounters 'top-down' urbanisation, or metropolisation. By combining a variety of disciplinary approaches on several different scales, through a study of spatial issues and social dynamics, this atlas not only enables the reader to gauge the impact of major projects on the lives of villages integrated into the city's fabric but also to re-establish the peri-urban village stratum as a fully-fledged actor in the diversity of this emerging metropolis.
