This book was released on 2016 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'intérêt d'utiliser des groupes de plateformes aériennes autonomes et hétérogènes, pour des missions telles que le Search and Rescue ou la surveillance de l'environnement, est désormais reconnu et avéré. Cependant, les opérations engageant plusieurs drones sont toujours limitées par le nombre d'opérateurs nécessaires à leur contrôle, et il est nécessaire d'inverser le ratio nombre d'opérateurs / nombre de drones. L'objectif de cette thèse est de contribuer à l'amélioration des performances cognitives de tels opérateurs, en traitant de la charge cognitive (CW), la conscience de situation (SA) et de la confiance dans les automatismes. Les contributions de la thèse concernent la gestion d'un modèle fonctionnel du drone et la mise en place de différentes niveaux de transparence informationnelle qui étendent l'approche traditionnelle PAC (Presentation-Abstraction-Control) pour la conception d'interface homme-machine. Le résultat de cette approche est une amélioration de la gestion du niveau d'autonomie système. Le modèle fonctionnel du drone est divisé en deux parties concernant respectivement la nature de la fonction et le degré d'agrégation de l'information. La présentation de ces informations est structurée de façon hiérarchique de façon à minimiser l'effort cognitif d'un opérateur devant contrôler plusieurs drones simultanément. Les concepts proposés dans la thèse ont été validés à travers différentes expérimentations, visant respectivement à mesurer l'effet de la nouvelle représentation fonctionnelle ainsi que du niveau d'autonomie sur la charge cognitive, sur la confiance. Les résultats montrent ainsi une amélioration en termes de charge cognitive, en termes de conscience de situation et en termes de temps de réponse à des événements inattendus.

This book was released on 2019 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette nouvelle ère de petits UAV qui peuplent actuellement l'espace aérien soulève de nombreuses préoccupations en matière de sécurité, en raison de l'absence de pilote à bord et de la nature moins précise des capteurs. Cela nécessite des approches intelligentes pour faire face aux situations d'urgence qui se produiront inévitablement pour toutes les catégories d'opérations d'UAV telles que définies par l'AESA (Agence européenne de la sécurité aérienne). Les limitations matérielles de ces petits véhicules suggèrent l'utilisation de la redondance analytique plutôt que la pratique habituelle de la redondance matérielle dans l'aviation humaine. Au cours de cette étude, des pratiques d'apprentissage automatique sont mises en œuvre afin de diagnostiquer les défaillances d'un petit drone à voilure fixe afin d'éviter le fardeau de la modélisation précise nécessaire au diagnostic par le modèle. Une méthode de classification supervisée, SVM (Support Vector Machines), permet de classer les défauts.Les données utilisées pour diagnostiquer les défauts sont les mesures de gyroscope et d'accéléromètre. L'idée de restreindre le jeu de données aux mesures d'accéléromètre et de gyroscope est de vérifier la capacité de classification de la méthode, avec un jeu de puces petit et peu coûteux, sans avoir à accéder aux données du pilote automatique, telles que les informations d'entrée de commande. Ce travail aborde les défauts dans les surfaces de contrôle d'un UAV. Plus précisément, les défauts considérés sont la surface de contrôle coincée en angle et la perte d'efficacité.Tout d'abord, un modèle d'aéronef est simulé. Ce modèle n'est pas utilisé pour la conception d'algorithmes FDD (Fault Detection and Diagnosis), mais est utilisé pour générer des données. Des données simulées sont utilisées à la place des données de vol pour isoler les effets probables du contrôleur sur le diagnostic, ce qui peut compliquer une étude préliminaire sur les FDD pour les drones. Les résultats montrent que pour les mesures simulées, SVM donne des résultats très précis sur la classification des défauts de perte d'efficacité sur les surfaces de contrôle. Ces résultats prometteurs appellent un complément d'investigation afin d'évaluer les performances du SVM en matière de classification des anomalies avec les données de vol. Des vols réels ont été organisés pour générer des données de vol erronées en manipulant le pilote automatique open source, Paparazzi. Toutes les données et le code sont disponibles dans le système de partage de code et de versions, Github. La formation est interrompue en raison du besoin de données étiquetées et du fardeau informatique lié à la phase de réglage des classificateurs. Les résultats montrent que, d'après les données de vol, SVM donne un score F1 de 0,98 pour la classification des failles bloquées à la surface de contrôle. En ce qui concerne les défauts de perte d'efficacité, il est nécessaire de recourir à certaines techniques d'ingénierie, impliquant l'ajout de mesures antérieures, pour obtenir les mêmes performances de classification. Un résultat prometteur est découvert lorsque les spinors sont utilisés comme caractéristiques au lieu de vitesses angulaires. Les résultats montrent qu'en utilisant les spinors pour la classification, la précision de la classification est considérablement améliorée, en particulier lorsque les classificateurs ne sont pas accordés. À l'aide de spinors et d'un noyau Gaussian, un classifieur sans accord donne un score F1 de 0,9555, soit 0,2712 lorsque les mesures gyroscopiques ont été utilisées. En résumé, ce travail montre que SVM donne une performance satisfaisante pour la classification des défauts sur les gouvernes d'un drone à l'aide de données de vol.

This book was released on 1998-04-17 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A work of enormous breadth, likely to pleasantly surprise both general readers and experts."—New York Times Book Review This revolutionary book provides fresh answers to long-standing questions of human origins and consciousness. Drawing on his breakthrough research in comparative neuroscience, Terrence Deacon offers a wealth of insights into the significance of symbolic thinking: from the co-evolutionary exchange between language and brains over two million years of hominid evolution to the ethical repercussions that followed man's newfound access to other people's thoughts and emotions. Informing these insights is a new understanding of how Darwinian processes underlie the brain's development and function as well as its evolution. In contrast to much contemporary neuroscience that treats the brain as no more or less than a computer, Deacon provides a new clarity of vision into the mechanism of mind. It injects a renewed sense of adventure into the experience of being human.

Available in PDF, EPUB and Kindle. Book excerpt: The ultimate book on the worldwide movement of hackers, pranksters, and activists collectively known as Anonymous—by the writer the Huffington Post says “knows all of Anonymous’ deepest, darkest secrets” “A work of anthropology that sometimes echoes a John le Carré novel.” —Wired Half a dozen years ago, anthropologist Gabriella Coleman set out to study the rise of this global phenomenon just as some of its members were turning to political protest and dangerous disruption (before Anonymous shot to fame as a key player in the battles over WikiLeaks, the Arab Spring, and Occupy Wall Street). She ended up becoming so closely connected to Anonymous that the tricky story of her inside–outside status as Anon confidante, interpreter, and erstwhile mouthpiece forms one of the themes of this witty and entirely engrossing book. The narrative brims with details unearthed from within a notoriously mysterious subculture, whose semi-legendary tricksters—such as Topiary, tflow, Anachaos, and Sabu—emerge as complex, diverse, politically and culturally sophisticated people. Propelled by years of chats and encounters with a multitude of hackers, including imprisoned activist Jeremy Hammond and the double agent who helped put him away, Hector Monsegur, Hacker, Hoaxer, Whistleblower, Spy is filled with insights into the meaning of digital activism and little understood facets of culture in the Internet age, including the history of “trolling,” the ethics and metaphysics of hacking, and the origins and manifold meanings of “the lulz.”

Download or read book Imagining the Global written by Fabienne Darling-Wolf and published by University of Michigan Press. This book was released on 2014-12-22 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a series of case studies of globally distributed media and their reception in different parts of the world, Imagining the Global reflects on what contemporary global culture can teach us about transnational cultural dynamics in the 21st century. A focused multisited cultural analysis that reflects on the symbiotic relationship between the local, the national, and the global, it also explores how individuals’ consumption of global media shapes their imagination of both faraway places and their own local lives. Chosen for their continuing influence, historical relationships, and different geopolitical positions, the case sites of France, Japan, and the United States provide opportunities to move beyond common dichotomies between East and West, or United States and “the rest.” From a theoretical point of view, Imagining the Global endeavors to answer the question of how one locale can help us understand another locale. Drawing from a wealth of primary sources—several years of fieldwork; extensive participant observation; more than 80 formal interviews with some 160 media consumers (and occasionally producers) in France, Japan, and the United States; and analyses of media in different languages—author Fabienne Darling-Wolf considers how global culture intersects with other significant identity factors, including gender, race, class, and geography. Imagining the Global investigates who gets to participate in and who gets excluded from global media representation, as well as how and why the distinction matters.

Download or read book Forensis written by Lawrence Abu Hamdan and published by . This book was released on 2014 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of material forensics in articulating new notions of the public truth of political struggle, violent conflict, and climate change are the focus of Forensis, the HKW exhibition catalog based on the theories of Eyal Weizman. - The concept of forensis was developed as a research project by Goldsmiths College, Centre for Research Architecture by theorist Eyal Weizman. The project is the subject of a major exhibition at the Haus der Kulturen der Welt (HKW) and catalog cum theoretical reader presenting the findings and contributions of over 20 influential architects, artists, filmmakers, and academics. Forensis, (Latin for pertaining to the forum ) argues for the role of material forensics as central to the interpretation of the ways in which states police and govern their subjects. Forensics engages struggles for justice across frontiers of contemporary conflict through the study of how technology mediates the testimony of material objects such as bones, ruins, toxic substances, etc. In the hopes of unlocking forensics potential as a political practice, the project participants present innovative investigations aimed at producing new kinds of evidence for use by international prosecutorial teams, political organizations, NGOs, and the UN.
Download or read book Manhunts written by Grégoire Chamayou and published by Princeton University Press. This book was released on 2012-07-22 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive history of manhunting in the West, from ancient times to the present Touching on issues of power, authority, and domination, Manhunts takes an in-depth look at the hunting of humans in the West, from ancient Sparta, through the Middle Ages, to the modern practices of chasing undocumented migrants. Incorporating historical events and philosophical reflection, Grégoire Chamayou examines the systematic and organized search for individuals and small groups on the run because they have defied authority, committed crimes, seemed dangerous simply for existing, or been categorized as subhuman or dispensable. Chamayou begins in ancient Greece, where young Spartans hunted and killed Helots (Sparta's serfs) as an initiation rite, and where Aristotle and other philosophers helped to justify raids to capture and enslave foreigners by creating the concept of natural slaves. He discusses the hunt for heretics in the Middle Ages; New World natives in the early modern period; vagrants, Jews, criminals, and runaway slaves in other eras; and illegal immigrants today. Exploring evolving ideas about the human and the subhuman, what we owe to enemies and people on the margins of society, and the supposed legitimacy of domination, Chamayou shows that the hunting of humans should not be treated ahistorically, and that manhunting has varied as widely in its justifications and aims as in its practices. He investigates the psychology of manhunting, noting that many people, from bounty hunters to Balzac, have written about the thrill of hunting when the prey is equally intelligent and cunning. An unconventional history on an unconventional subject, Manhunts is an in-depth consideration of the dynamics of an age-old form of violence.
