Download or read book Aide la conception d un atelier flexible written by Françoise Deloule and published by . This book was released on 1987 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'atelier flexible est un outil de production performant de plus en plus nécessaire aux entreprises qui veulent rester compétitives. Sa conception est complexe. Nous avons donc, dans un premier temps, recherché les méthodes et outils existants, nécessaires aux différentes phases de son élaboration et aux différents aspects qu'il revêt. Un Atelier Flexible se compose d'un système sous-ensembles inter-dépendants. Nous avons choisi comme cadre, MERISE, méthode de conception qui s'adapte bien aux problèmes des Ateliers Flexibles. Dans un deuxième temps, nous avons centré notre recherche sur le problème posé par le dimensionnement du système physique de l'atelier. De ses caractéristiques dépendent en effet sa capacité de production en terme de quantité, qualité et rapidité d'élaboration du produit. Modélisation et simulation s'avèrent alors indispensables et complémentaires pour cerner le problème et apporter des réponses au problème complexe posé par l'imbrication des incidences des variations des différents paramètres qui entrent en jeu. D'autre part, elles permettent de définir les éléments nécessaires à l'élaboration des cahiers des charges établis pour les choix de matériel. Nous proposons donc une démarche structurée pour utiliser au mieux la simulation et pour franchir les différentes étapes du dimensionnement afin d'obtenir une solution finale correcte et optimisée par rapport à certains critères. Elle apporte donc une aide appréciable à la conception d'un Atelier Flexible.

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 Object Oriented Software Components for the Modelling and Simulation of a Styrene Polymerisation Reactor written by Maik Skowronski and published by . This book was released on 2000 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail décrit la conception et la mise en oeuvre de composants logiciels orientés objets pour la modélisation et la simulation d'une application industrielle, une unité de polymérisation du styrène. Le prototype de simulateur dévéloppé repose sur trois composants logiciels : un composant dédié aux calculs des propriétés thermodynamiques et basé sur ATOM; DISCo, solveur numérique de systèmes d'équations différentielles et algébriques et PROPOLY, bibliothèque de modèles élémentaires spécifiques à l'application. PROPOLY repose sur une décomposition structurelle du procédé de polymérisation suivant une hiérarchie. Cette décomposition conduit aux concepts d'éléments technologiques et de ports. L'élément technologique constitue le volume de contrôle sur lequel les bilans matière et énergie sont établis. Un port est défini comme l'abstraction du lieu sur un élément technilogique où la matière, l'énergie ou l'information entre ou sort. L'implémentation a été réalisée sur la base d'une conception et analyse orientées objet, notamment la méthode UML et le langage C++. PRPOLY a été validé par rapport à l'installation industrielle par comparaison entre les valeurs culculées et des données expérimentales relatives à des modes de fonctionnement statique et dynamique.
Download or read book Mod lisation modulaire de syst mes articul s Conception orient e objet de plates formes de simulation written by Nicolas Seguy and published by . This book was released on 2003 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: En vue de la réalisation d'une plate-forme de simulation interactive, ce travail de thèse propose une modélisation modulaire des équations du mouvement de systèmes multicorps à partir de méthodes de pénalité. Un système dynamique est alors décrit comme un assemblage de sous-systèmes contraints possédant leurs propres modèles et méthodes de résolution. La stabilité numérique est assurée par un calcul automatique des facteurs de pénalité introduits au niveau des liaisons et un processus itératif basé sur un formalisme de Lagrangien augmenté au niveau des composants. Les formalismes et les méthodes de résolution retenues respectent les propriétés de flexibilité afin d'assurer une modification aisée de la topologie du système. Cet assemblage de composants autonomes est adapté à une programmation orientée-objet qui permet l'ajout ou la suppression dynamiques d'instances des classes de bases. L'outil de simulation autorise alors des modifications interactives de la scène virtuelle.
Download or read book Agroecological Transitions From Theory to Practice in Local Participatory Design written by Jacques-Eric Bergez and published by Springer. This book was released on 2019-02-28 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book presents feedback from the ‘Territorial Agroecological Transition in Action’- TATA-BOX research project, which was devoted to these specific issues. The multidisciplinary and multi-organisation research team steered a four-year action-research process in two territories of France. It also presents: i) the key dimensions to be considered when dealing with agroecological transition: diversity of agriculture models, management of uncertainties, polycentric governance, autonomies, and role of actors’ networks; ii) an operational and original participatory process and associated boundary tools to support local stakeholders in shifting from a shared diagnosis to a shared action plan for transition, and in so doing developing mutual understanding and involvement; iii) an analysis of the main effects of the methodology on research organisation and on stakeholders’ development and application; iv) critical analysis and foresights on the main outcomes of TATA-BOX, provided by external researchers.

Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --
Download or read book Rammed Earth Structures written by Julian Keable and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ramming earth has been a method of construction for centuries in many parts of the world and the technique can produce buildings that are strong, durable, safe and desirable. Because earth is an abundant and cheap resource, rammed earth buildings are often very economical. To achieve the best results the right techniques for the selection and testing of soils must be used to protect walls from water damage and shrinkage. This book aims to show how high standards can be achieved and the criteria on which rammed earth structures and building techniques can be judged. Since the fi rst edition of this book was published, the standards described in Rammed Earth Structures has been adopted as a Building Standard in Zimbabwe. Further progress is being made extending the use of rammed earth as an officially sanctioned building material across all SADC countries. This book is now therefore becoming an important guide and resource for those wishing to employ this economical and low-carbon building material in the construction of public as well as private buildings in Africa and elsewhere.
