Book excerpt: LA THESE EST ORGANISEE EN TROIS PARTIES: LA PARTIE I TRAITE DE LA MODELISATION DES SYSTEMES A EVENEMENTS DISCRETS ET DES SYSTEMES HYBRIDES. APRES AVOIR PRESENTE UNE REVUE CRITIQUE DE LA LITTERATURE RELATIVE A LA MODELISATION DES SYSTEMES A EVENEMENTS DISCRETS ET DES SYSTEMES HYBRIDES, NOUS PROPOSONS UNE APPROCHE SYSTEMIQUE DE LA MODELISATION DES SYSTEMES A EVENEMENTS DISCRETS, APPROCHE QUE NOUS GENERALISONS POUR LES SYSTEMES HYBRIDES. LA PARTIE II PROPOSE UNE REFORMULATION DE LA THEORIE DES RESEAUX DE PETRI. L'IDEE DE BASE EST DE CONSIDERER COMME ACTION ATOMIQUE, NON PLUS LE TIR D'UNE ET UNE SEULE TRANSITION, MAIS LE TIR D'UN MULTI-ENSEMBLE POSITIF DE TRANSITIONS. L'ENSEMBLE DES NOTIONS FONDAMENTALES GENERALISEES ET INTRODUITES CONSTITUE LA BASE DE LA THEORIE D'UN NOUVEAU FORMALISME PERMETTANT DE PRENDRE EN COMPTE DE MANIERE UNIFIEE LES PRINCIPALES REGLES DE TIR PROPOSEES POUR LES RESEAUX DE PETRI: LES MACHINES DE PETRI. NOUS GENERALISONS LES PRINCIPES METHODES D'ANALYSE DES RESEAUX DE PETRI ET MONTRONS, PARMI D'AUTRES RESULTATS, QUE CERTAINES CLASSES DE MACHINES DE PETRI ADMETTENT UNE CARACTERISATION VECTORIELLE DES SITUATIONS DE CONFLIT EFFECTIF. LA PARTIE III PROPOSE TROIS FORMALISMES MACHINES DE PETRI NON AUTONOMES. DANS LE CADRE METHODOLOGIQUE PROPOSE DANS LA PARTIE I, NOUS MONTRONS LE BENEFICE QU'APPORTENT CES FORMALISMES POUR LA COMMANDE ET LA SIMULATION DES SYSTEMES A EVENEMENTS DISCRETS ET DES SYSTEMES HYBRIDES. AU FIL DE LA THESE, NOTRE CONTRIBUTION EST ILLUSTREE PAR PLUSIEURS EXEMPLES DE SYSTEMES DE PRODUCTION ET D'APPLICATIONS TEMPS REEL

This book was released on 1998 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'UTILISATION DU MODELE RESEAU DE PETRI CONTINU A VITESSES MAXIMALES CONTROLABLES (RDPCVC), NOUS A CONDUIT A PRESENTER UN CERTAIN NOMBRE DE METHODOLOGIES POUR L'ANALYSE ET LA COMMANDE DES SYSTEMES DE PRODUCTION. LA THEORIE DES SYSTEMES CONTINUS, PERMET D'ETUDIER DEUX PROPRIETES RELATIVES A L'ANALYSE DES SYSTEMES A EVENEMENTS DISCRETS EN GENERAL ET LES SYSTEMES DE PRODUCTION EN PARTICULIER : LA STABILITE ET L'ACCESSIBILITE. L'ETUDE DE LA STABILITE UTILISE UNE APPROCHE BASEE SUR LE PRINCIPE DE COMPARAISON. LA PROPRIETE D'ACCESSIBILITE CONCERNE LE DOMAINE DES MARQUAGES ACCESSIBLES REPRESENTANT LE DOMAINE DE VARIATION DES NIVEAUX MOYENS DES STOCKS DES LIGNES DE FABRICATION. L'ENSEMBLE DES ALGORITHMES ETABLIS PERMET UNE DETERMINATION SYSTEMATIQUE DES DOMAINES DE MARQUAGES ACCESSIBLES STATIONNAIRES. SUITE A LA RESOLUTION DU PROBLEME DE L'ACCESSIBILITE, NOUS AVONS ENONCE DES PROPRIETES DONNANT DES CONDITIONS NECESSAIRES ET / OU SUFFISANTES SUR LE CHOIX DES NIVEAUX MOYENS DESIRES DES STOCKS. LES NIVEAUX MOYENS DES STOCKS CONSTITUENT UN ETAT EVOLUTIF DU SYSTEME DONT ON A ETUDIE LA COMMANDE EN BOUCLE OUVERTE. LE CALCUL DE LA COMMANDE EST BASE SUR DES METHODES D'OPTIMISATION SOUS CONTRAINTES. LES RESULTATS DE CETTE ETUDE NOUS ONT SERVI A RESOUDRE UN PROBLEME PRATIQUE, CELUI DE LA COMMANDE DU FLUX DE SORTIE DE CES LIGNES. POUR ETENDRE L'ETUDE DE LA COMMANDE DU FLUX DE SORTIE A UNE CLASSE PLUS LARGE DE SYSTEMES DE PRODUCTION NOUS AVONS ELABORE UNE SECONDE APPROCHE INSPIREE DES TRAVAUX DE SHARIFNIA ET EGILMEZ. EN TENANT COMPTE DES CONTRAINTES DE CAPACITE DANS LA PROCEDURE DE SYNTHESE DE LA COMMANDE ET EN NE REPRESENTANT PAR UN MODELE RDPCVC QUE LA PARTIE OPERATIVE DU SYSTEME, LE MODELE ANALYTIQUE RDPCVC D'UNE CLASSE DE SYSTEMES DE PRODUCTION EST LINEAIRE ET STATIONNAIRE. L'UTILISATION DU PRINCIPE DE L'INVARIANCE POSITIVE DES DOMAINES ENGENDRES PAR LES CONTRAINTES, NOUS A PERMIS DE DEDUIRE DES CONDITIONS SUFFISANTES GARANTISSANT L'EXISTENCE D'UN RETOUR D'ETAT LINEAIRE POUR CES SYSTEMES.

Book Synopsis Lake Pavin by : Télesphore Sime-Ngando
Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

This book was released on 1996 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes a événements discrets sont caractérises par un espace d'état discret et par une dynamique régie par l'occurrence d'événements asynchrones. Cette thèse traite de leur étude par réseaux de pétri, le seul formalisme (mathématique et graphique) permettant à la fois leur spécification fonctionnelle, leur modélisation et leur évaluation. Le modèle d'un système complexe est souvent un réseau de pétri (rdp) de grande taille qu'il est difficile d'analyser. Il peut toutefois être obtenu en composant des rdp connus de telle façon que les propriétés locales restent valables globalement. Apres un rappel des techniques de composition de rdp généralises et des conditions de conservation des propriétés d'invariance, on définit des rdp de base pour en déduire une technique d'analyse par décomposition. Cette méthode est ensuite étendue aux rdp colores, une extension concise et générale mais d'analyse habituellement délicate, et sa simplicité est soulignée par plusieurs exemples (notamment celui d'un système flexible de production). Enfin, on décrit une nouvelle voie pour prendre en compte les aléas dans la modélisation. Elle permet d'éviter l'énumération exhaustive des défaillances possibles (dont les procédures de reprise doivent être intégrées au rdp modélisant le fonctionnement normal) et de se passer d'un systeme de surveillance externe au modèle, ou au moins de les simplifier. Tout le problème de la reprise revient a déterminer les états successifs du système, c'est-a-dire a définir une séquence ; c'est pourquoi on introduit une représentation des rdp colores fondée sur une structure algébrique de l'ensemble des couleurs. Celle-ci simplifie beaucoup la modélisation de problèmes de séquencèrent et autorise des modifications dynamiques de séquence.

This book was released on 2012-11-05 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the selected papers of the first I.D.M.M.E. conference on 'Integrated Design and Manufacturing in Mechanical Engineering', held in Nantes from 15-17 April 1996. Its objective was to discuss the questions related to the definition of the optimal design and manufacturing processes and to their integration through coherent methodologies in adapted environments. The initiative of the Conference and the organization thereof, is mainly due to the efforts of the french PRIMECA group (Pool of Computer Resources for Mechanics) started eight years ago. We were able to attract the internationru community with the support of the International Institution for Production Engineering Research (C.I.R.P.). The conference brought together two hundred and fifty specialists from around the world. 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.

Book Synopsis The Parody Exception in Copyright Law by : Sabine Jacques
Download or read book The Parody Exception in Copyright Law written by Sabine Jacques and published by Oxford University Press. This book was released on 2019-03-07 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parodies have been created throughout times and cultures. A glimpse at the general judicial latitude generally afforded to parodies, satires, caricatures, and pastiches demonstrates the social and cultural value of this particular form of artistic expression. With the advent of technologies and the evolution of copyright legislation, creative endeavours in the form of parody gathered a new youth but became unlawful. While copyright law grants exclusive rights to right-holders, this right is not absolute. Legislation includes specific exceptions, which preclude right-holders from exercising their prerogatives in particular cases which foster creativity and cultural diversity within that society. The parody exception pertains to this ultimate objective by permitting users to reproduce copyright-protected materials for the purpose of parody. To understand the meaning and scope of the parody exception, this book examines and compares five jurisdictions which differ in their protection of parodies: France, Australia, Canada, the US and the United Kingdom. This book is concerned with finding an appropriate balance between the protection awarded to right-holders and the public interest. This is achieved by analysing the parody exception to the economic rights of right-holders, the preservation of moral rights and the interaction of the parody exception with contract law. As parodies constitute an artistic expression protected under the right to freedom of expression, this book also considers the influence of freedom of expression on the interpretation of this specific copyright exception. Furthermore, this book aims at providing guidance on how to resolve conflicts where fundamental rights are in conflict. This is the first book in English to offer an in-depth investigation into the parody exception in copyright law, and comments on industry practices linked to this form of creative endeavours.
