This book was released on 1997 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans cette etude, nous presentons une extension du theoreme d'adaptation aux cas des geomateriaux sous sollicitations dynamiques. Le comportement du sol sous de telles sollicitations est fortement non-lineaire et presente un caractere dissipatif qui n'existe pas dans un milieu elastique ; ces caracteristiques doivent etre prises en compte pour obtenir des solutions raisonnables. L'effet de l'ecrouissage (cinematique lineaire et isotrope) est pris en compte par l'utilisation du concept des materiaux standards generalises. Le caractere dissipatif est represente par l'introduction d'une matrice de rigidite complexe. L'amortissement est introduit dans la loi de comportement et conduit aux memes solutions formelles que la loi d'elasticite lineaire. Les modules complexes sont definis uniquement pour une excitation harmonique, mais une classe tres large d'excitation peut etre decomposee en une somme de fonctions harmoniques par l'application de la transformee de fourier. D'ou la generalisation de l'approche par modules complexes a l'etude des systemes soumis a une excitation quelconque. L'introduction d'une matrice de rigidite complexe permet de tenir compte de l'amortissement mais pas des non-linearites physiques, ces dernieres sont prises en compte a travers le concept de l'adaptation lui-meme. L'approche developpee est appliquee pour l'etude du comportement des chaussees sous sollicitations de type impulsif. La procedure numerique pour l'etude de l'adaptation plastique est basee sur le couplage de la methode des elements finis avec la programmation mathematique non-lineaire qui donne ainsi le facteur de securite contre la defaillance.

This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: L'analyse d'adaptation permet d'évaluer le comportement élasto-plastique de structures soumises à des charges variables vis-à-vis de la défaillance par déformations inélastiques accumulées. Le domaine d'adaptation, obtenu dans l'espace des charges, est fourni pour une quelconque histoire de chargement inscrite dans ce domaine ; les informations concernant la physionomie exacte des champs de contrainte et de déformation ne sont pas explicitement recherchées. La formulation théorique classique de cette analyse repose sur des hypothèses restrictives qui peuvent devenir irréalistes : c'est la cas notamment de l'hypothèse de linéarité géométrique qui ne peut s'appliquer dans le cas de structures plaques ou coques. La partie théorique de la présente étude propose d'étendre le premier théorème d'adaptation. L'approche géométriquement non linéaire est développée via le formalisme propre aux grandes déformations élasto-plastiques ; l'introduction d'une décomposition multiplicative originale du tenseur gradient des déformations totales permet d'obtenir une analogie avec la théorie classique. Une étude comparative explicite les liaisons avec les approches non linéaires précédentes. L'une de ces approches est exploitée numériquement en liaison avec un calcul non linéaire pas-à-pas ; les résultats obtenus concernent les coques de révolution sous charges axisymétriques en grands déplacements. Dans les problèmes considérés, les changements de géométrie de la structure sont tels qu'ils permettent à celle-ci de rester stable
Download or read book A Theory of Adaptation written by Linda Hutcheon and published by Routledge. This book was released on 2012-08-21 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Theory of Adaptation explores the continuous development of creative adaptation, and argues that the practice of adapting is central to the story-telling imagination. Linda Hutcheon develops a theory of adaptation through a range of media, from film and opera, to video games, pop music and theme parks, analysing the breadth, scope and creative possibilities within each. This new edition is supplemented by a new preface from the author, discussing both new adaptive forms/platforms and recent critical developments in the study of adaptation. It also features an illuminating new epilogue from Siobhan O’Flynn, focusing on adaptation in the context of digital media. She considers the impact of transmedia practices and properties on the form and practice of adaptation, as well as studying the extension of game narrative across media platforms, fan-based adaptation (from Twitter and Facebook to home movies), and the adaptation of books to digital formats. A Theory of Adaptation is the ideal guide to this ever evolving field of study and is essential reading for anyone interested in adaptation in the context of literary and media studies.

Available in PDF, EPUB and Kindle. Book excerpt: The third in a series of Cedefop publications dealing with technical aspects of the European Qualification Framework and European Credit Transfer System, this book analyses current practice in countries that have made progress with evaluating and defining competence. It proposes a typology of knowledge, skills and competence, to be used not as an instrument of 'harmonisation' between countries, but as a template to enable comparison. The aim is to promote mobility in every sense, bringing work-based learning and knowledge acquired in higher education closer together.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Download or read book Your Mindful Compass written by Andrea Maloney Schara and published by . This book was released on 2013-12-01 with total page 318 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Philosophy in a Time of Terror written by Giovanna Borradori and published by University of Chicago Press. This book was released on 2013-05-28 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for Philosophy in a Time of Terror was born hours after the attacks on 9/11 and was realized just weeks later when Giovanna Borradori sat down with Jürgen Habermas and Jacques Derrida in New York City, in separate interviews, to evaluate the significance of the most destructive terrorist act ever perpetrated. This book marks an unprecedented encounter between two of the most influential thinkers of our age as here, for the first time, Habermas and Derrida overcome their mutual antagonism and agree to appear side by side. As the two philosophers disassemble and reassemble what we think we know about terrorism, they break from the familiar social and political rhetoric increasingly polarized between good and evil. In this process, we watch two of the greatest intellects of the century at work.

Available in PDF, EPUB and Kindle. Book excerpt: "'Gender Matters' is a manual aimed to assist educators and youth leaders work on issues of gender and gender-based violence with young people. This publication presents theoretical information, methods and resources for education and training activities, along with concrete exercises that users can put into practice in their daily work. Violence is a serious issue which directly affects the lives of many young people. It often results in lasting damage to their well-being and integrity, putting even their lives at risk. Gender-based violence, including violence against women, remains a key human rights challenge in contemporary Europe and in the world. Working with young people on human rights education is one way of preventing gender-based violence from occurring. By raising awareness on why and how it manifests and exploring its impact on people and in society, gender-based violence will no longer go undetected. Gender really does matter, to women, to men, to young people - to all of us. This manual serves to explore these human rights issues and act upon them."--Book jacket.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
