Book excerpt: Les travaux présentés dans cette thèse sont relatifs à l’organisation de l’activité d’un contrôleur central chargé de la coordination des machines d’un système de production flow-shop. Le contrôleur réagit aux sollicitations des machines en traitant les messages de requête qui lui sont envoyés et en retournant des messages de réponse. L’objectif visé consiste à optimiser les performances des systèmes considérés, notamment en minimisant le makespan. La problématique d’ordonnancement associée s’exprime F, C1/pmtnc, permu, block, Tj/Cmax selon la notation dc Graham que nous étendons pour prendre en compte les spécificités des systèmes étudiés. La construction d’un modèle paramétrable à l’aide du formalisme des réseaux de Petri colorés temporisés et son exécution nous ont permis de simuler de nombreuses configurations de systèmes flow-shop contrôlés. L’impact du contrôleur sur le niveau de performances des systèmes étudiés est mis en évidence lors de l’analyse des résultats de simulation. Son influence varie selon la règle de tri utilisée pour sélectionner le message de requête à traiter à chaque instant. Nous établissons alors une borne de contrôle qui montre que, dans certains cas, le contrôleur central devient la ressource critique du système de production et en constitue alors le goulot d’étranglement. Après une étude des conditions d’atteignabilité de la cadence de production optimale, nous formulons des propositions pour un ordonnancement en ligne efficace de l’activité du contrôleur à partir de règles de tri basées sur les algorithmes EDF et LLF et que nous nommons respectivement EoDF et LoLF.

Book excerpt: LA GESTION ET L'OPTIMISATION DES FLUX MATIERES DANS LES SYSTEMES DE PRODUCTION SONT COMPLEXES ET CONCERNENT DIFFERENTS DOMAINES : LA RECHERCHE OPERATIONNELLE, L'AIDE A LA DECISION, LA MODELISATION ET LA SPECIFICATION DES SYSTEMES DE NOMBREUX SYSTEMES DE PRODUCTION A FLUX DISCRETS PEUVENT ETRE ANALYSES AVEC LE MODELE DU FLOW-SHOP HYBRIDE, MODELE QUE NOUS AVONS ETENDU AVEC LA NOTION DE HIERARCHISATION. NOUS DONNONS UNE EXPLICATION DE CE QU'EST UN PROBLEME DE FLOW-SHOP HYBRIDE HIERARCHISE ET DES EXEMPLES DE PLUSIEURS SYSTEMES INDUSTRIELS CONCERNES AVANT DE DEFINIR UN CADRE METHODOLOGIQUE COMPLET POUR LA RESOLUTION DE CETTE PROBLEMATIQUE (DE L'ANALYSE DES SYSTEMES A LA MISE EN UVRE DES SOLUTIONS). NOUS PROPOSONS TOUS LES MODELES NECESSAIRES (MODELES EA, MODELES DE SPECIFICATION ET MODELE OBJET (POUR LA CONSTRUCTION DE MODELES DE SIMULATION)) PERMETTANT DE TRAITER UN PROBLEME DE FLOW-SHOP HYBRIDE. NOUS RESOLVONS PLUS PARTICULIEREMENT DEUX PROBLEMES D'OPTIMISATION COMBINATOIRE RENCONTRES DANS LES FLOW-SHOP HYBRIDES : LE PROBLEME DU TRANSPORT ENTRE DEUX ETAGES ET LE CALCUL D'UNE AFFECTATION PREDICTIVE DES JOBS SUR LES RESSOURCES D'UN ETAGE. LE PROBLEME DU TRANSPORT EST RESOLU PAR UN CHOIX DYNAMIQUE DE REGLES DE GESTION PRENANT EN COMPTE L'ETAT INSTANTANE DU SYSTEME. LA RESOLUTION DU PROBLEME D'AFFECTATION MET EN UVRE UNE COMBINAISON DE DEUX ALGORITHMES DE RECUIT SIMULE ET D'UNE HEURISTIQUE. NOUS PRESENTONS LE PROTOTYPE D'UN OUTIL METTANT EN UVRE CES TECHNIQUES. LES PERSPECTIVES DE CES TRAVAUX S'ORIENTENT ESSENTIELLEMENT D'UNE PART VERS LE DEVELOPPEMENT D'UN ENVIRONNEMENT LOGICIEL INTEGRE COUVRANT TOUT LE PROCESSUS DE RESOLUTION ET D'AUTRE PART VERS UNE RESOLUTION GLOBALE DU PROBLEME DE FLOW-SHOP HYBRIDE.

Available in PDF, EPUB and Kindle. Book excerpt: The psychology of eating is regulated by neural mechanisms. When not well controlled, eating may result in disorders and health hazards such as obesity, type 2 diabetes mellitus, and vascular diseases. Lifestyles and cultures influence eating habits, thus there are differences in the prevalence of health problems depending upon living environments. This book examines the psychology and the pathophysiological outcomes of eating. Chapters address such topics as the influence of lifestyle, circadian rhythm, sleep, and fragrant odors on appetite and weight regulation; the impact of glucose, sucrose, lactate, and ketone bodies on the brain; the consequences of glycation stress on the skeletal muscle; and much more.

Book excerpt: This book provides an overview of key issues with regards to implementing telemedicine services as well as an in depth overview of telemedicine in pulmonary, critical care, and sleep medicine. Topics range from specific practices to program development. Telemedicine has experienced explosive growth in recent years and yet, implementing telemedicine solutions is complex with substantial regulatory, legal, financial, logistical, and intra-organization/intra-personal barriers that must be overcome. This book provides the necessary information and guidance to address those complex issues. This book is broadly divided into two parts 1) a primer on requisite steps before embarking on telemedicine service development and 2) specific applications and examples where telemedicine is successfully utilized to improve quality of care in pulmonary, critical care, and sleep medicine. The first part includes coverage of telemedicine and finance, regulatory and legal issues, and program development. The second part delves into specifics with information on ambulatory telemedicine programs, inpatient consultations, and tele-ICU programs. All chapters are written by interprofessional authors that are leaders in the field of telemedicine with extensive knowledge of diverse telemedicine programs and robust real-world experience on the topic. This is an ideal guide for telehealth program managers, and pulmonary, critical care, and sleep medicine professionals interested in improving their telehealth practice.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: A guide to applying software design principles and coding practices to VHDL to improve the readability, maintainability, and quality of VHDL code. This book addresses an often-neglected aspect of the creation of VHDL designs. A VHDL description is also source code, and VHDL designers can use the best practices of software development to write high-quality code and to organize it in a design. This book presents this unique set of skills, teaching VHDL designers of all experience levels how to apply the best design principles and coding practices from the software world to the world of hardware. The concepts introduced here will help readers write code that is easier to understand and more likely to be correct, with improved readability, maintainability, and overall quality. After a brief review of VHDL, the book presents fundamental design principles for writing code, discussing such topics as design, quality, architecture, modularity, abstraction, and hierarchy. Building on these concepts, the book then introduces and provides recommendations for each basic element of VHDL code, including statements, design units, types, data objects, and subprograms. The book covers naming data objects and functions, commenting the source code, and visually presenting the code on the screen. All recommendations are supported by detailed rationales. Finally, the book explores two uses of VHDL: synthesis and testbenches. It examines the key characteristics of code intended for synthesis (distinguishing it from code meant for simulation) and then demonstrates the design and implementation of testbenches with a series of examples that verify different kinds of models, including combinational, sequential, and FSM code. Examples from the book are also available on a companion website, enabling the reader to experiment with the complete source code.
