This book highlights peer reviewed articles from the 1st International Conference on Renewable Energy and Energy Conversion, ICREEC 2019, held at Oran in Algeria. It presents recent advances, brings together researchers and professionals in the area and presents a platform to exchange ideas and establish opportunities for a sustainable future. Topics covered in this proceedings, but not limited to, are photovoltaic systems, bioenergy, laser and plasma technology, fluid and flow for energy, software for energy and impact of energy on the environment.
Cette thèse aborde la question de l'intérêt des systèmes multi-agents pour la capitalisation des connaissances. Cela consiste à maitriser la sauvegarde, la récupération, et la réutilisation des connaissances. Le thème étant très vaste, nous avons limité l'étude à un domaine plus restreint celui de la capitalisation des connaissances d'un groupe de recherche. Nous soutenons l'hypothèse qu'une approche de capitalisation fondée sur la technologie des systèmes multi-agents (SMA) permet de représenter, en plus des connaissances traditionnelles, des connaissances relatives à la manière dont les gens organisent les ressources de leur environnement de travail pour accomplir ses tâches professionnelles. Quatre contributions sont apportées à cette étude : une démarche pour la détermination des agents nécessaires à un tel système ; un modèle pour représenter les contextes de travail des membres d'un groupe ; un mécanisme qui utilise les représentations des contextes de travail pour proposer des actions à un nouveau membre du groupe de façon proactive et un exemple de mise en œuvre concernant la spécification des agents d'un système pour capitaliser les connaissances d'un groupe de recherche. Dans l'étude des mécanismes pour l'implantation des SMA pour la capitalisation des connaissances, notre contribution concerne la détermination des agents, la modélisation des utilisateurs, la définition d'un mécanisme pour rendre les agents proactifs, et la spécification d'un système de capitalisation de connaissances d'un groupe de recherche.
CETTE THESE DECRIT L'ARCHITECTURE FONCTIONNELLE D'UN ATELIER DE SPECIFICATION DEFINI DANS LE PROJET MARS. L'OBJECTIF EST DE CONCEVOIR UN ATELIER LOGICIEL OUVERT ENCHAINANT LES PHASES DE SPECIFICATION, DE VALIDATION ET DE GENERATION DE SYSTEMES. NOTRE PROPOSITION D'ARCHITECTURE RESULTE, D'UNE SYNTHESE DES BESOINS SPECIFIQUES DE MODELISATION ET D'ANALYSE DE SYSTEMES, ET DE L'ETUDE DES PRINCIPALES COMPOSANTES DES ATELIERS DE GENIE LOGICIEL. NOUS DETAILLONS PLUS PARTICULIEREMENT LES COMPOSANTES SYSTEMES. NOTRE ARCHITECTURE REPOSE SUR UNE GESTION MULTI-UTILISATEURS ET MULTI-SESSIONS DANS UN ENVIRONNEMENT DISTRIBUE HETEROGENE. L'UTILISATION D'UN META-MODELE FACILITE L'INTEGRATION DE NOUVELLES APPLICATIONS. NOUS PRESENTONS LA REALISATION D'UN PROTOTYPE: L'ATELIER AMI (ATELIER DE MODELISATION INTERACTIF) REGROUPANT DES SERVICES ALLANT DE LA MODELISATION GRAPHIQUE A LA GENERATION DE CODE A PARTIR DE SPECIFICATIONS ORIENTEES RESEAUX DE PETRI. L'ATELIER POSSEDE UN PROGRAMME D'INTERFACE UTILISATEUR MACAO, BASE SUR UN META-MODELE DE GRAPHES, ASSURANT L'INTRODUCTION DES DONNEES ET LA VISUALISATION GRAPHIQUE DES RESULTATS DANS DES FORMALISMES EXTENSIBLES
This book provides a comprehensive state-of-the-art, in conceptual modeling. It grew out of research papers presented at the 18th International Conference on Conceptual Modeling (ER '99) and arranged by the editors. The plan of the conference is to cover the whole spectrum of conceptual modeling as it relates to database and information systems design and to offer a complete coverage of data and process modeling, database technology, and database applications. The aim of the conference and of these proceedings is to present new insights related to each of these topics. This book contains both selected and invited papers. The 33 selected papers are organized in 11 sessions encompassing the major themes of the conference, especially : - schema transformation, evolution, and integration - temporal database design - views and reuse in conceptual modeling - advanced conceptual modeling - business process modeling and workflows - data warehouse design. Besides the selected papers, 3 invited papers present the views of three keynote speakers, internationally known for their contribution to conceptual modeling and database research and for their active role in knowledge dissemination. Peter Chen presents the results of his ongoing research on ER model, XML, and the Web. Georges Gardarin presents the first results of an ESPRIT project federating various data sources with XML and XML-QL. Finally, Matthias Jarke develops a way to capture and evaluate the experiences gained about process designs in so-called process data warehouses.
This volume constitutes the refereed proceedings of the 15th International Conference on Conceptual Modeling, ER '96, held in Cottbus, Germany, in October 1996. The volume presents three invited contributions together with 29 revised full papers selected from 110 submissions. The papers cover all current aspects of the entity-relationship approach and conceptual modeling; they are organized in sections on advanced schema design, processes, query languages, representation, integration, principles of database design, transformation, enhanced modelling, capturing design information, and evolution.
The era of chemical and biological megadeath is upon us, and the potential of deadly biowarfare attacks from governments, militant independent groups, and even individuals is far greater than it has been at any time in the past. At this time, more than twenty-five countries are developing, or have stockpiles of chemical and biological weapons, in many cases in sufficient quantities to wipe out the entire population of the world. So far the danger of chemical and biological aggression has been little acknowledged, and, at least in America, little prepared for by federal and local government. Most terrorist threats and attacks are not widely reported in the mainstream media. Although information about the proliferation of man-made diseases is carefully suppressed by governments and the media they will be covered in the pages of this book. Not only is America unprepared and ignorant of what is happening, but the people in government and scientific professions who do know, who should be warning the American public about the dangers of chemical and biological terrorism, are instead doing their utmost to hide this information from us; information that is vital for our survival.The information that is contained in the pages of this book will not be measured or calculated to reassure people that everything is fine, when reassurance is the exact opposite of what is needed at this time. It may even give you nightmares when you realise the real circumstance that we are in. The information in the pages that follow will be the truth about the biowarfare threat to America.
This book constitutes the refereed joint proceedings of five international workshops held in conjunction with the 24th International Conference on Conceptual Modeling, ER 2005, in Klagenfurt, Austria, in October 2005. The 40 revised full papers presented together with the abstracts of seven tutorials were carefully reviewed and selected from 102 submissions. The papers are organized in topical sections on best practices of UML, experience reports and new applications, model evaluation and requirements modeling, metamodeling and model driven development, positions in engineering agent oriented systems, agent oriented methodologies and conceptual modeling, agent communication and coordination, geographic information systems, spatial and spatio-temporal data representation, spatial relations, spatial queries, analysis and data mining, data modeling and visualisation, conceptual modeling approaches for e-business, information system models quality, and quality driven processes.
This book constitutes the proceedings of the 12th International Conference on Design Science Research in Information Systems and Technology, DESRIST 2017, held in May/June 2017 in Karlsruhe, Germany. The 25 full and 11 short papers presented in this volume were carefully reviewed and selected from 66 full and 19 short papers. The contributions are organized in topical sections named: DSR in business process management; DSR in human computer interaction; DSR in data science and business analytics; DSR in service science; methodological contributions; domain-specific DSR applications; emerging themes and new ideas; and products and prototypes.
