This book was released on 1996 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes automatisés de production, ayant acquis des performances importantes en fonctionnement normal, doivent aussi être réactifs face aux perturbations de la fabrication. Une analyse est réalisée sur ces systèmes pour la proposition de stratégies d'exploitation utilisant le potentiel des alternatives de configuration pour l'exécution de la fabrication. Pour apporter des solutions a ce problèmes, divers critères existent, allant de l'intervention humaine aux réponses automatisées. Prenant en compte l'organisation hiérarchique du système, la réaction est entreprise au niveau de la conduite pour le cas des défaillances des ressources. Les configurations alternatives possibles du système représentent des modes dégradés de fonctionnement, comportant des performances variées, qui doivent être évaluées pour la prise de décision. Un modèle des modes de marche est défini pour la conduite du système, comme outil d'assistance à sa réactivité. Les alternatives comprennent la reprise après réparation, le fonctionnement dégradé des ressources et le réordonnancement des opérations. La solution pour la reprise de la fabrication est suggérée à travers une démarche qui comprend les étapes de génération, d'évaluation, de vérification et de spécification des alternatives. La contribution de cette étude réside en la caractérisation des modes dégradés de fonctionnement, par une réaction rapide basée sur une évaluation des temps de fabrication. Une méthode de réaction est proposée, intégrant les stratégies de solution en fonction de l'urgence et du respect des contraintes de production. La décision prend en compte les consignes de la gestion de production, l'état réel des ressources et les données de la maintenance. La méthode comprend des stratégies à court terme, utilisant le mode dégradé ou la réparation de la ressource défaillante et des stratégies à moyen terme par reconfiguration du système, évaluées par le calcul des durées de fabrication. Une application sur des exemples permet l'évaluation de la méthode développée.

Available in PDF, EPUB and Kindle. Book excerpt: LA BIBLIOGRAPHIE SUR LES SYSTEMES AUTOMATISES DE PRODUCTION RECONNAIT LARGEMENT L'IMPORTANCE DES MODES DE MARCHE (ET D'ARRET) DANS LE CYCLE DE VIE DES S.A.P., AUSSI BIEN DANS LA PHASE DE CONCEPTION QUE DANS LA PHASE D'EXPLOITATION. MAIS IL EXISTE ACTUELLEMENT FORT PEU D'OUTILS PERMETTANT DE LES MODELISER OU DE LES INTEGRER LORS DE LA CONCEPTION. L'OBJECTIF DE CETTE THESE EST DE PROPOSER UNE APPROCHE UNIFIEE DES MODES DE MARCHE D'UN S.A.P. PARTANT D'UN POINT DE VUE G.E.M.M.A., ON MODELISE LE COMPORTEMENT DE CHACUN DES DIFFERENTS COMPOSANTS ELEMENTAIRES D'UN ATELIER PAR UN AUTOMATE FINI DETERMINISTE DONT LES ETATS SONT LES MODES DE MARCHE, LES TRANSITIONS ETANT LES COMMUTATIONS ENTRE MODES. PUIS, PAR COMPOSITION, EN RESPECTANT LA STRUCTURE FORTEMENT HIERARCHIQUE D'UN S.A.P., EN INTEGRANT LES INTERACTIONS ET LES CONTRAINTES DE FONCTIONNEMENT ENTRE COMPOSANTS, ET EN EFFECTUANT A CHAQUE NIVEAU DE LA HIERARCHIE UNE ABSTRACTION PAR ENCAPSULATION DES NIVEAUX INFERIEURS, ON MODELISE LE COMPORTEMENT DU S.A.P. DANS SA GLOBALITE. CETTE DEMARCHE S'ACCOMPAGNE, EN OUTRE, DE LA CONSTRUCTION D'UN GESTIONNAIRE POUR CHAQUE NIVEAU D'ENCAPSULATION, GESTIONNAIRE CONSTITUANT UNE MODELISATION DU LOGICIEL DE COMMANDE A METTRE EN UVRE. LA MODELISATION A L'AIDE D'AUTOMATES FINIS DETERMINISTES PERMET UNE FORMALISATION DES DIFFERENTES OPERATIONS EFFECTUEES. UN PREMIER CHAPITRE INTRODUCTIF PRESENTE LE CONTEXTE DE CETTE RECHERCHE, CELUI DES S.A.P., ET ON Y SITUE LA NOTION DE MODE DE MARCHE PAR RAPPORT AUX DIFFERENTS TERMES ET AUX DIFFERENTES INTERPRETATIONS RENCONTREES. LE SECOND CHAPITRE EXPOSE LE MODELE AVEC LES CARACTERISTIQUES ET LES CONTRAINTES PRISES EN COMPTE PAR CETTE APPROCHE; LE TROISIEME EN EFFECTUE SA SPECIFICATION FORMELLE. LE QUATRIEME ET DERNIER CHAPITRE EST UN EXEMPLE DE SA MISE EN UVRE DANS LE CADRE DES LANGAGES DE CONFIGURATION

This book was released on 1991 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans un second temps, nous avons montré que l'intégration des tables de contraintes aboutit à une décomposition structurelle et fonctionnelle: elle est obtenue sous la forme d'un schéma arborescent de recherche déductive des modes de marche des différentes machines du procédé. Ce modèle est facilement exploitable peut être utilisé par la suite, en vue du pilotage temps réel de l'unité de production par un raisonnement sur la logique de dépendance ou d'enchaînement de ses modes de marche. L'exploitation de la modélisation nous a amené à étudier le pilotage d'une unité de production flexible. Nous en avons décrit les différentes fonctionnalités et les solutions adoptées pour résoudre tous les problèmes de fonctionnement, qui se répercutent à tous les niveaux de commande. La mise en œuvre d'un logiciel de pilotage, chargé de la gestion automatique des modes de marche, a permis de valider complètement la démarche, avec l'utilisation de techniques d'intelligence artificielle

Download or read book Strategies for Sustainable Financing of Secondary Education in Sub Saharan Africa written by Keith M. Lewin and published by World Bank Publications. This book was released on 2008-02-27 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investment in secondary schooling in Sub-Saharan Africa has been neglected since the World Conference on Education for All at Jomtien. The World Education Forum at Dakar began to recognize the growing importance of post-primary schooling for development. Only 25 percent of school-age children attend secondary school in the region--and fewer complete successfully, having consequences for gender equity, poverty reduction, and economic growth. As universal primary schooling becomes a reality, demand for secondary schools is increasing rapidly. Gaps between the educational levels of the labor force in Sub-Saharan Africa and other regions remain large. Girls are more often excluded from secondary schools than boys. Secondary schooling costs are high to both governments and households. This study explores how access to secondary education can be increased. Radical reforms are needed in low-enrollment countries to make secondary schooling more affordable and to provide more access to the majority currently excluded. The report identifies the rationale for increasing access, reviews the status of secondary education in Sub-Saharan Africa, charts the growth needed in different countries to reach different levels of participation, identifies the financial constraints on growth, and discusses the reforms needed to make access affordable. It concludes with a road map of ways to increase the probability that more of Africa's children will experience secondary schooling.
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 The Sounds of Early Cinema written by Richard Abel and published by Indiana University Press. This book was released on 2001-10-03 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sounds of Early Cinema is devoted exclusively to a little-known, yet absolutely crucial phenomenon: the ubiquitous presence of sound in early cinema. "Silent cinema" may rarely have been silent, but the sheer diversity of sound(s) and sound/image relations characterizing the first 20 years of moving picture exhibition can still astonish us. Whether instrumental, vocal, or mechanical, sound ranged from the improvised to the pre-arranged (as in scripts, scores, and cue sheets). The practice of mixing sounds with images differed widely, depending on the venue (the nickelodeon in Chicago versus the summer Chautauqua in rural Iowa, the music hall in London or Paris versus the newest palace cinema in New York City) as well as on the historical moment (a single venue might change radically, and many times, from 1906 to 1910).

Download or read book The Transmission of Well being written by Margarida Durães and published by Peter Lang. This book was released on 2009 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: What does well-being mean when we talk about men and women in the past? Their sheer chances of survival, their protection from want, their social status, their individual agency and their self-esteem were all strongly mediated by the family, the predominant social institution. Family laws and customs of family formation created differences between insiders and outsiders in terms of well-being. Within families, there were strong differences in autonomy, status and freedom between the genders and generations. The book offers a fascinating exploration of gender differences in well-being in many regions of historic Europe, with some comparative perspectives. It explores how historic family systems differed with respect to choosing a marriage partner, transmitting property, living and care conditions of widows and widowers and the position of children born out of wedlock.
Download or read book Gender Inequalities Households and the Production of Well Being in Modern Europe written by Tindara Addabbo and published by Routledge. This book was released on 2016-04-22 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feminist scholars have long pointed out the relevance of the unpaid work that goes on within European households in sustaining the well-being of the continent's populations. However, care work and domestic labour continue to be largely unremunerated and unequally distributed by gender. This unique volume of interdisciplinary essays casts new light on the roles that households play in securing the well-being of individuals and families, uncovering the processes of bargaining and accommodation, and conflict and compromise that underpin them. Contributors put gender at the centre of their analyses, demonstrating the uneven experiences of men and women as both providers and receivers of welfare in European households, in both the past and the present. As European states grapple with changing family forms, a growing population of dependent people, increased participation of women in labour markets and a profound shift in the nature and organisation of work, this book makes a timely contribution to our understanding of the critical role played by households in mediating processes of economic and social change. It offers new challenges to scholars, researchers and policy makers eager to address gender inequalities and enhance well-being. This book is the second of four volumes being published as part of Ashgate's 'Gender and Well-Being' series that arise from a programme of international symposia funded by the European Science Foundation under the auspices of COST (European Cooperation in the field of Scientific and Technical Research).
Download or read book Abnormal written by Michel Foucault and published by Verso Books. This book was released on 2016-09-01 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three decades after his death, Michel Foucault remains one of the towering intellectual figures of the last half-century. His works on sexuality, madness, the prison, and medicine are enduring classics. From 1971 until his death in 1984, Foucault gave public lectures at the famous Collge de France. These seminal events, attended by thousands, created the benchmarks for contemporary social enquiry. The lectures comprising Abnormal begin by examining the role of psychiatry in modern criminal justice, and its method of categorising individuals who "resemble their crime before they commit it." Building on the themes of societal self-defence developed in earlier works, Foucault shows how defining "normality" became a prerogative of power in the nineteenth century, shaping the institutions-from the prisons to the family-meant to deal with "monstrosity," whether sexual, physical, or spiritual. The Collge de France lectures add immeasurably to our appreciation and understanding of Foucault's thought.
