Available in PDF, EPUB and Kindle. Book excerpt: Différentes lois variant selon le type de la surface de commutation choisie et leur synthèse basée sur des contraintes LMI sont proposées. La variation ou la méconnaissance des retards présents dans un système limite les performances en asservissement. Une solution consiste à développer des commandes adaptatives indirectes nécessitant une identification en temps réel des paramètres du système dont le retard. Ceci nécessite d'abord une réflexion sur la possibilité de pouvoir identifier ces paramètres (problème de l'identifiabilité) et la mise en œuvre d'algorithme d'identification, points qui font l'objet de la troisième partie. La quatrième partie concerne le problème de la mise en œuvre de lois de commande à retards distribués en montrant que le choix d'une implémentation particulière pour ce type de lois de commande doit faire l'objet d'une étude particulière si l'on veut éviter le phénomène d'instabilité. Après une conclusion, quelques perspectives concernant l'analyse et la commande des systèmes à retards sont données.

Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse étudie la compensation robuste d'un retard de commande affectant un système dynamique. Pour répondre aux besoins du domaine applicatif du contrôle moteur, nous étudions d'un point de vue théorique des lois de contrôle par prédiction, dans les cas de retards incertains et de retards variables, et présentons des résultats de convergence asymptotique. Dans une première partie, nous proposons une méthodologie générale d'adaptation du retard, à même de traiter également d'autres incertitudes par une analyse de Lyapunov-Krasovskii. Cette analyse est obtenue grâce à une technique d'ajout de dérivateur récemment proposée dans la littérature et exploitant une modélisation du retard sous forme d'une équation à paramètres distribués. Dans une seconde partie, nous établissons des conditions sur les variations admissibles du retard assurant la stabilité du système boucle fermée. Nous nous intéressons tout particulièrement à une famille de retards dépendant de la commande (retard de transport). Des résultats de stabilité inspirés de l'ingalité Halanay sont utilisés pour formuler une condition de petit gain permettant une compensation robuste. Des exemples illustratifs ainsi que des résultats expérimentaux au banc moteur soulignent la compatibilité de ces lois de contrôle avec les impératifs du temps réel ainsi que les mérites de cette approche.

Available in PDF, EPUB and Kindle. Book excerpt: Dans cette thèse, on considère la problématique de la stabilité et de la stabilité robuste d'une classe de systèmes linéaires / à retards distribués. Notre travail est motivé par le nombre croissant de modèles en allant de la biologie vers les réseaux de communication et de transport, modèles qui peuvent être inclus dans la classe générale considérée dans la thèse. Nous développons deux approches complémentaires, géométriques et algébriques. Ces approches nous permettent de dériver les régions de stabilité dans l'espace de paramètres défini par (délai moyen, retard de propagation). En d'autres termes, nous obtenons des conditions nécessaires et suffisantes pour la stabilité des systèmes appartenant à la classe considérée. Dans la thèse, diverses applications sont présentées. D'abord, nous précisons quelques propriétés qualitatives au sujet de la stabilité de quelques modèles en biologie et en communication dans des réseaux. Ensuite, nous développons une méthode afin d'étudier un modèle récent de la dynamique du réseau de transport qui inclut un effet de mémoire. Des exemples numériques illustratifs complètent la présentation.

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.

Download or read book Spatial Prepositions written by Claude Vandeloise and published by University of Chicago Press. This book was released on 1991-10-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This striking study of the meaning and use of the major spatial prepositions in French provides valuable insight into how the human mind organizes spatial relationships. Most previous analyses of spatial prepositions have assumed that their semantic properties can be adequately explained by familiar logical and geometrical concepts. Thus, the standard view of the preposition "in" as it appears in the sentence "the ball is in the bag" postulates that it refers to the geometrical relation of inclusion. This paradigm, however, falters when faced with the contrast in acceptability between sentences such as "the bulb is in the socket" and "the bottle is in the cap." The force exerted by the "landmark" (a conceptually fixed object) on the "target" (a moveable object) is crucial in this difference: the functional notion of containment seems more operational in the use of the preposition "in" than inclusion. That is, what are taken to be the landmark and the target depend greatly on the functions these objects serve in the human scheme. This offers important clues to otherwise problematic linguistic quirks, such as why one sleeps in one's bed, while one is said to lie on one's deathbed. While many of the examples apply in English as well as French, there are some noteworthy differences—in French one sits on a chair, but in a couch. Vandeloise convincingly argues that it is precisely this subjective element which makes a standard geometrical account unfeasible.

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 Cognitive Approaches to Lexical Semantics written by Hubert Cuyckens and published by Walter de Gruyter. This book was released on 2009-06-23 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collected volume presents radically new directions which are emerging in cognitive lexical semantics research. A number of papers re-ignite the polysemy vs. monosemy debate, and testify to the fact that polysemy is no longer simply taken for granted, but is currently a much more contested issue than it was in the 1980s and 1990s. Other papers offer fresh perspectives on the prototype structure of lexical categories, while generally accepted notions about the radial network structure of categories are questioned in papers on the development of word meaning in child language acquisition and in diachrony. Additional topics include the interaction of lexical and constructional meaning, and the relationship between word meanings and the contexts in which the words are encountered. This book is of interest to semanticists and cognitive linguists, as well as to scholars working in the broader field of cognitive science.
