Available in PDF, EPUB and Kindle. Book excerpt: La problématique étudiée dans cette thèse concerne le maintien de l'intégrité de robots mobiles en milieux naturels. L'objectif est de fournir des lois de commande permettant de garantir l'intégrité d'un véhicule lors de déplacements autonomes en milieux naturels à vitesse élevée (5 à 7 m.s -1 ) et plus particulièrement dans le cadre de l'agriculture de précision. L'intégrité s'entend ici au sens large. En effet, l'asservissement des déplacements d'un robot mobile peut générer des consignes nuisant à son intégrité physique, ou à la réalisation de sa tâche (renversement, tête-à-queue, stabilité des commandes, maintien de la précision, etc.). De plus, le déplacement en milieux naturels amène des problématiques liées notamment à des conditions d'adhérence variables et relativement faibles (d'autant plus que la vitesse du véhicule est élevée), ce qui se traduit par de forts glissements des roues sur le sol, ou encore à des géométries de terrains non traversables par le robot. Aussi, cette thèse vise à déterminer en temps réel l'espace de stabilité en terme de commandes admissibles permettant de modérer les actions du robot. Après une présentation des modélisations existantes, et des observateurs permettant l'exploitation de ces modélisations pour la mise en place de loi de commande prédictive en braquage pour le suivi de trajectoire, une nouvelle méthode d'estimation des glissements basé sur une observation cinématique est proposée. Celle-ci permet de répondre aux problématiques de vitesse variable (et notamment du passage de la vitesse par des valeurs nulles) du véhicule et d'observation lors d'un déplacement sans trajectoire de référence. Ce nouvel observateur est primordial pour la suite des développements de cette thèse, puisque la suite des travaux s'intéresse à la modulation de la vitesse du véhicule. Ainsi, dans la suite des travaux, deux lois de commande prédictives agissant sur la vitesse du véhicule ont été mises en place. La première apporte une solution à la problématique de la saturation des actionneurs en braquage, lorsque la vitesse ou les glissements rendent la trajectoire à suivre inadmissible vis-à-vis des capacités physiques du véhicule. La deuxième répond à la problématique de la garantie de la précision du suivi de trajectoire (maintien du véhicule dans un couloir de déplacement). Dans les deux cas la stratégie de commande est similaire : on prédit l'état futur du véhicule en fonction de ses conditions d'évolution actuelle et de conditions d'évolutions futures simulées (obtenues grâce à la simulation de l'évolution d'un modèle dynamique du véhicule) afin de déterminer la valeur de la vitesse optimale pour que les variables cibles (dans un cas la valeur du braquage et dans l'autre l'écart à la trajectoire) respectent les conditions imposées (non-dépassement d'une valeur cible). Les résultats présentés dans ce mémoire ont été réalisés soit en simulations, soit en conditions réelles sur des plateformes robotiques. Il en découle que les algorithmes proposés permettent dans un cas de réduire la vitesse du véhicule pour éviter la saturation du braquage et donc les phénomènes de sur et sous virage qui en découlerait et donc permet de conserver la commandabilité du véhicule. Et dans l'autre cas de garantir que l'écart à la trajectoire reste sous une valeur cible.

Book excerpt: "Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Available in PDF, EPUB and Kindle. Book excerpt: The essays in this edited volume, written in English and French, tackle the intriguing problems of fear and safety by analysing their various meanings and manifestations in literature and other narrative media. The articles bring forth new, cross-cultural interpretations on fear and safety through examining what kinds of genre-specific means of world-making narratives use to express these two affectivities. The articles also show how important it is to study these themes in order to understand challenges in times of global threats, such as the climate crisis. The main themes of the book are approached from various theoretical perspectives as related to their literary and cultural representations. Recent trends in research, such as affect and risk theory, serve as the basis for the discussion. The articles in the volume also draw from disciplines such as gender studies and trauma studies to examine the threats posed by collective fears and aggression on individuals' lives and propose ways of coping with fear. These themes are addressed also in articles analysing new adaptations of old myths that retell stories of the past. Many of the articles in the volume discuss apocalyptic and dystopian narratives that currently permeate the entire cultural landscape. Dystopian narratives do not only deal with future threats, such as totalitarianism, technocracy, or environmental disasters, but also suggest alternative ways of being and new hopes in the form of political resistance.

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: A striking account of a colony for the mentally ill that forces a reconsideration of madness in society. What happens when the mentally ill are not isolated from society but are instead welcomed into it and invited to take a place in the fabric of the community? Are fear and rejection replaced by the understanding and sympathy often engendered by familiarity? Or are the barriers between the sane and the mad only strengthened? We have experienced a taste of this scenario in the U.S. in the last decade with the new emphasis on de-institutionalization, but Denise Jodelet takes us to an extraordinary community in France where the mentally ill have assumed a visible and prominent role for more than seventy years. The small French town of Ainay-le-Ch�teau and its environs are the site of a "family colony" for men, established in 1900. Here the patients ("lodgers") live with ordinary families ("foster parents"), hold jobs, and are free to move about the countryside. Jodelet's chronicle of daily life in the colony is made rich and vivid by extensive ethnographic material as she unravels a complex set of relationships, ultimately finding that while some of the barriers between the "other" and the larger society have been overcome, new ones have arisen in their place. This unique social experiment provides invaluable social and cultural insights, illuminating many fundamental issues in psychology, psychiatry, and sociology.

Book excerpt: Few issues engender so much heat between Christians as the topic of creation. Reasonable, calm, and supremely well informed, this is a book written by someone who is passionate about both science and the Bible. 'I hope,' says Denis Alexander, 'that reading it will encourage you to believe, as I do, that the 'Book of God's Word' and the 'Book of God's Works' can be held firmly together in harmony.' This substantial new edition updates the science, and extends the author's discussion of the theological implications.
