Book excerpt: On étudie dans cette thèse des méthodes de localisation coopérative de robots mobiles sans utilisation de mesures extéroceptives relatives, comme des angles ou des distances entre robots. Les systèmes de localisation considérés sont basés sur des mesures de radionavigation sur des balises fixes ou des satellites. Pour ces systèmes, on observe en général un écart entre la position observée et la position réelle. Cet écart systématique (appelé biais) peut être dû à une mauvaise position de la balise ou à une différence entre la propagation réelles des ondes électromagnétiques par rapport aux conditions standard utilisées pour établir les modèles d'observation. L'influence de ce biais sur la localisation des robots est non négligeable. La coopération et l'échange de données entre les robots (estimations des biais, estimations des positions et données proprioceptives) est une approche qui permet de corriger ces erreurs systématiques. La localisation coopérative par échange des estimations est sujette aux problèmes de consanguinité des données qui peuvent engendrer des résultats erronés, en particulier trop confiants. Lorsque les estimations sont utilisées pour la navigation autonome à l'approche, on doit éviter tout risque de collision qui peut mettre en jeu la sécurité des robots et des personnes aux alentours. On doit donc avoir recours à un mécanisme d'intégrité vérifiant que l'erreur commise reste inférieure à une erreur maximale tolérable pour la mission. Dans un tel contexte, il est nécessaire de caractériser des domaines de confiance fiables contenant les positions des robots mobiles avec une forte probabilité. L'utilisation des méthodes ensemblistes à erreurs bornées est considérée alors comme une solution efficace. En effet, ce type d'approche résout naturellement le problème de consanguinité des données et fournit des domaines de confiance fiables. De surcroît, l'utilisation de modèles non-linéaires ne pose aucun problème de linéarisation. Après avoir modélisé un système coopératif de nr robots avec des mesures biaisées sur des balises, une étude d'observabilité est conduite. Deux cas sont considérés selon la nature des mesures brutes des observations. En outre, des conditions d'observabilité sont démontrées. Un algorithme ensembliste de localisation coopérative est ensuite présenté. Les méthodes considérées sont basées sur la propagation de contraintes sur des intervalles et l'inversion ensembliste. La coopération est effectuée grâce au partage des positions estimées, des biais estimés et des mesures proprioceptives.L'échange des estimations de biais permet de réduire les incertitudes sur les positions des robots. Dans un cadre d'étude simple, la faisabilité de l'algorithme est évaluée grâce à des simulations de mesures de distances sur balises en utilisant plusieurs robots. La coopération est comparée aux méthodes non coopératives. L'algorithme coopératif ensembliste est ensuite testé sur des données réelles en utilisant deux véhicules. Les performances de la méthode ensembliste coopérative sont enfin comparées avec deux méthodes Bayésiennes séquentielles, notamment une avec fusion par intersection de covariance. La comparaison est conduite en termes d'exactitude et d'incertitude.

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.

Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Available in PDF, EPUB and Kindle. Book excerpt: This interdisciplinary volume brings together specialists from different backgrounds to deliver expert views on the relationship between morality and emotion, putting a special emphasis on issues related to emotional shocks. One of the distinctive aspects of social existence today is our subjection to traumatic events on a global scale, and our subsequent embodiment of the emotional responses these events provoke. Covering various methodological angles, the contributors ensure careful and heterogeneous reflection on this delicate topic. With eleven original essays, the collection spans a wide variety of fields from philosophy and literary theory, to the visual arts, history, and psychology. The authors cover diverse themes, including philosophical approaches to political polarization; the impact of negative emotions such as anger on inter-relational balance; humour and politics; media and the idea of progress; photography and trauma discourse; democratic morality in modern Indian society; emotional olfactory experiences; phenomenological readings of spatial disorientation, and the significance of moral shocks. This timely volume offers crucial perspectives on contemporary questions relating to ethical behaviours, and the challenges of a globalized society on the verge of political, financial and emotional collapse.

Book excerpt: Watsuji Tetsuro's Rinrigaku (literally, the principles that allow us to live in friendly community) has been regarded as the definitive study of Japanese ethics for half a century. In Japan, ethics is the study of human being or ningen. As an ethical being, one negates individuality by abandoning one's independence from others. This selflessness is the true meaning of goodness.

Book excerpt: This anthology aims to present the fundamental philosophical issues and tools required by the reflection within and upon geography and Geographic Information Systems (GIS) . It is an introduction to the philosophy for GIScience from an analytical perspective, which looks at GIS with a specific focus on its fundamental and most general concepts and distinctions. The first part of the book is devoted to explore some of the main philosophical questions arising from GIS and GIScience, which include, among others, investigations in ontology, epistemology, linguistics and geometrical modeling. The second part concerns issues related to spatial and cartographical representations of the geographical world. The third part is focused on the ontology of geography, specifically in terms of geographical entities, objects and boundaries. Finally, in the fourth part, the topic of GIS constitutes a starting point for exploring themes such as quantum geography and disorientation, and for defining professional profiles for geographers with competences in GIS environment. This book on a new and unexplored field of research could be a fundamental point of reference for professional philosophers and geographers interested in the theoretical reflection about the foundational concepts of GIScience. It is also interesting reading material for students (both undergraduates, postgraduates and Ph.D. students) in philosophy, geography, applied ontology, GIScience, geomatics and computer science.

Available in PDF, EPUB and Kindle. Book excerpt: Before Saturday March 26th 2005, "Doctor Who" had been off the air as a regular, new TV series for more than fifteen years; until a production team led by Russell T. Davies re-imagined the programme so successfully, so triumphantly, that it's become an instant Christmas tradition, a BAFTA winner, an international 'superbrand' and a number one rated show. It's even been credited with reinventing family TV. This is the first full-length book to explore the 'new Who' phenomenon through to the casting of Matt Smith as the new Doctor. It explores "Doctor Who" through contemporary debates in TV Studies about quality TV and how can we define TV series as both 'cult' and 'mainstream'. Further, the book challenges assumptions in focusing on the importance of breath-taking, dramatic moments along with narrative structures, and in analysing the significance of Murray Gold's music as well as the series' visual representations. Matt Hills is a lifelong "Who" fan and he also considers the role of fandom in the show's return. He investigates too the multi-generic identity, the monster-led format, and the time-travelling brand of BBC Wales' 'Doctor Who'. In the twenty-first century, TV is changing, but the last of the Time Lords has been more than ready: he's been fantastic.

This book was released on 2016-08-31 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: There's a common belief that cyberspace cannot be regulated-that it is, in its very essence, immune from the government's (or anyone else's) control.Code argues that this belief is wrong. It is not in the nature of cyberspace to be unregulable; cyberspace has no "nature." It only has code-the software and hardware that make cyberspace what it is. That code can create a place of freedom-as the original architecture of the Net did-or a place of exquisitely oppressive control.If we miss this point, then we will miss how cyberspace is changing. Under the influence of commerce, cyberpsace is becoming a highly regulable space, where our behavior is much more tightly controlled than in real space.But that's not inevitable either. We can-we must-choose what kind of cyberspace we want and what freedoms we will guarantee. These choices are all about architecture: about what kind of code will govern cyberspace, and who will control it. In this realm, code is the most significant form of law, and it is up to lawyers, policymakers, and especially citizens to decide what values that code embodies.

Book excerpt: Highlights the trailers, merchandising and cultural conversations that shape our experiences of film and television It is virtually impossible to watch a movie or TV show without preconceived notions because of the hype that precedes them, while a host of media extensions guarantees them a life long past their air dates. An onslaught of information from print media, trailers, internet discussion, merchandising, podcasts, and guerilla marketing, we generally know something about upcoming movies and TV shows well before they are even released or aired. The extras, or “paratexts,” that surround viewing experiences are far from peripheral, shaping our understanding of them and informing our decisions about what to watch or not watch and even how to watch before we even sit down for a show. Show Sold Separately gives critical attention to this ubiquitous but often overlooked phenomenon, examining paratexts like DVD bonus materials for The Lord of the Rings, spoilers for Lost, the opening credits of The Simpsons, Star Wars actions figures, press reviews for Friday Night Lights, the framing of Batman Begins, the videogame of The Thing, and the trailers for The Sweet Hereafter. Plucking these extra materials from the wings and giving them the spotlight they deserve, Jonathan Gray examines the world of film and television that exists before and after the show.
