Book excerpt: LES CAHIERS DES CHARGES D'AUTOMATISATION ET LES SPECIFICATIONS DES BESOINS DES UTILISATEURS SONT DES POINTS TRES IMPORTANTS POUR LA QUALITE DES SYSTEMES DE COMMANDE DES SYSTEMES DE PRODUCTION ET LA MAITRISE DE LEUR COUT DE DEVELOPPEMENT. CES INFORMATIONS SONT POURTANT EN REGLE GENERALE PEU FORMALISEES VOIRE PARFOIS PAS EXPRIMEES EXPLICITEMENT. L'OBJET DE CETTE THESE EST DE SPECIFIER UNE METHODE QUI PERMETTE DE GUIDER L'EXPRESSION ET LA FORMALISATION DES BESOINS DE COMMANDE, EN VUE DE L'INTEGRATION DE L'ACTIVITE DE CONCEPTION DE LA COMMANDE, QUI VA UTILISER CES INFORMATIONS, DANS UNE DEMARCHE COHERENTE DE DEVELOPPEMENT DES SYSTEMES DE COMMANDE. LA METHODE PROPOSEE REPOSE SUR LA CONSTRUCTION PROGRESSIVE D'UN MODELE DU COMPORTEMENT ATTENDU POUR LE SYSTEME CONSTITUE DU PROCESSUS DE PRODUCTION, DES PRODUITS ET DE LA COMMANDE. LA STRUCTURE DU MODELE EST REALISEE PAR UN ENSEMBLE HIERARCHISE D'OBJETS QUI CORRESPONDENT AUX ENTITES TANGIBLES DU SYSTEME DE PRODUCTION. CETTE STRUCTURE CORRESPOND ALORS A CELLE DU PROCESSUS ET EST FACILEMENT COMPREHENSIBLE PAR LES SPECIALISTES DU PROCESSUS. ELLE PERMET UNE APPROCHE PROGRESSIVE DU PROBLEME QUI EST BASEE SUR LA DEFINITION DE DIFFERENTS NIVEAUX D'ABSTRACTION. LES SPECIFICATIONS COMPORTEMENTALES SONT GUIDEES PAR DES PRINCIPES BASES SUR LA NOTION D'OBJECTIFS ET SONT FORMALISES A L'AIDE DES STATECHARTS.

This book was released on 2013-04-01 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: La mise en place d’un logiciel sans défaut reste primordiale pour plusieurs domaines qui requièrent des applications dites de sécurité comme les transports. La réalisation d’un modèle formel est l’approche la plus efficace pour atteindre l'objectif du zéro défaut, que ce soit en termes de temps ou de maîtrise de la complexité. Ce modèle permet d’analyser et de vérifier le comportement d’un logiciel. Cet ouvrage présente la méthode B, une méthode formelle s’appuyant sur la preuve de propriétés qui, sur la base d’une spécification et de la notion de raffinement, permet d’aller jusqu’à la production automatique de code. Différents outils découlant de cette méthode ainsi que des exemples concrets d’utilisations industrielles de différentes tailles sont aussi exposés dans des domaines tels que l’avionique ou les systèmes manufacturiers.

This book was released on 2001 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les travaux s'inscrivent dans le cadre d'une ingénierie système afin de faciliter, au plus tôt, une représentation commune et consensuelle des services attendus d'un système automatisé par les différents acteurs du procédé d'automatisation. Ils ont pour objet de proposer, notamment dans la phase initiale de spécification, une méthode formelle vérifiant le prédicat d'automatisation : Spécifications des processus de commande ^ Spécifications des processus opérants => Spécifications des objectifs "système". De manière complémentaires aux travaux développés en Automatique, dans le cadre de la théorie de la Supervision, pour lesquels les objectifs du système à automatiser et les comportements des processus opérants sont parfaitement connus et modélisés, notre approche se caractérise par un processus incrémental de spécification, basé sur le langage B, permettant aux acteurs d'un processus d'automatisation d'aboutir progressivement à une vision commune et cohérente du système automatisé.

Available in PDF, EPUB and Kindle. Book excerpt: La spécification complète de la conduite des systèmes de production nécessite différents approches et formalismes afin de tenir compte de ses différents aspects (système hétérogène).Couvrir tous les aspects d'un système hétérogène est ramené au problème d'intégration de différentes méthodes sous une approche globale d'analyse et de décomposition (approche multi-formalismes). Deux cas de systèmes hétérogènes ont été étudiés. Le premier cas est celui d'un système réactif et transformationnel ou nous avons proposé l'intégration des méthodes SA/RT et SC sous une approche fonctionnelle globale. Le deuxième cas concerne les systèmes comportant, en plus des sous-systèmes réactifs et transformationnels, des sous-systèmes d'information. Pour ce type de systèmes, nous avons proposé l'intégration des méthodes SA/RT, SC, MI et OMT sous une approche globale basée sur le concept de domaine et d'objet domaine. Afin d'intégrer des méthodes formelles (VDM) dans le cycle de developpement d'un système, Nous avons proposé une démarche de passage d'un modèle semi-formel à un modèle formel. Cette démarche s'applique aussi bien dans le cas d'un développement fonctionnel que d'un développement orienté objet. Il a été étudié en particulier le passage d'un modèle semi-formel SA-RT à un modèle formel VDM. Les différentes approches sont illustrées à travers des études de cas sur un exemple de cellule d'usinage.

This book was released on 2014-02-26 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le terme promotion de la santé en Afrique, près de 30 ans après l'adoption de la Charte d'Ottawa, continue d'avoir des connotations complètement hors du sens que lui confère cette charte. Cela n'est pas étonnant quand on sait que la notion de santé dans ce contexte africain équivaut à la lutte contre la maladie à travers les soins de santé dispensés par des professionnels de la santé dans des formations sanitaires et les hôpitaux. L'évolution que connait le continent depuis quelques décennies est de donner un peu plus de place à la communauté à travers les relais communautaires dans une participation communautaire vidée de son contenu, car le pouvoir n'est jamais passé entre les mains des communautés.C'est au vu de tout ceci que le présent ouvrage à sa raison d'être pour expliquer les fondements de l'autonomisation communautaire et de la promotion de la santé avec leur importance pour la région africaine en proie aux mauvais indicateurs de santé comparativement aux autres régions du monde.

About ninety papers and twenty posters were presented covering three main topics : optimization and evaluation of the product design process, optimization and evaluation of the manufacturing systems and methodological aspects.

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). Contributors include Richard Abel, Rick Altman, Edouard Arnoldy, Mats Björkin, Stephen Bottomore, Marta Braun, Jean Châteauvert, Ian Christie, Richard Crangle, Helen Day-Mayer, John Fullerton, Jane Gaines, André Gaudreault, Tom Gunning, François Jost, Charlie Keil, Jeff Klenotic, Germain Lacasse, Neil Lerner, Patrick Loughney, David Mayer, Domi-nique Nasta, Bernard Perron, Jacques Polet, Lauren Rabinovitz, Isabelle Raynauld, Herbert Reynolds, Gregory A.

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 Dealmaking written by Richard Razgaitis and published by John Wiley & Sons. This book was released on 2004-04-16 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applying practical tools to the volatile process of negotiating Prognosticators apply Monte Carlo Analysis (MCA) to determine the likelihood and significance of a complete range of future outcomes; Real Options Analysis (ROA) can then be employed to develop pricing structures, or options, for such outcomes. Richard Razgaitis' Dealmaking shows readers how to apply these powerful valuation tools to a variety of business processes, such as pricing, negotiating, or living with a "deal," be it a technology license, and R&D partnership, or an outright sales agreement. Dealmaking distinguishes itself from other negotiating guides not only by treating negotiations as an increasingly common situation, but also by presenting a tool-based approach that creates flexible, practical valuation models. This forward-thinking guide includes a variety of checklists, case studies, and a CD-ROM with the appropriate software. Richard Razgaitis (Bloomsbury, NJ) is a Managing Director at InteCap, Inc. He has over twenty-five years of experience working with the development, commercialization, and strategic management of technology, seventeen of which have been spent in the commercialization of intellectual property.
