On the Interoperability of DEVS components: On-Line vs. Off-Line Strategies

During the last years, the DEVS community provides many contributions towards the realization of a world-wide platform for collaborative Modeling & Simulation. The goal of such a platform would be to enable the sharing and reuse of models between scientists, as well as the seamless simulation of distributed and heterogeneous models. Therefore, one of the major research fields is the definition of architectures for integrating heterogeneous DEVS components, meaning simulators and/or models written in different frameworks and programming languages. In this work, we present three different strategies for providing such interoperability between DEVS components. The first focuses on standardizing exchanges between simulators, and has been explored in previous works. The two others strategies are more prospective; in keeping with Model-Driven Engineering, they place the model at the center of their architecture and make extensive use of model transformations. To make this possible, we defined a platform and language-independent format for describing and sharing DEVS models, called DEVS Markup Language

Syndrome Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) : à propos d’un cas au Sénégal: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome: A case report in Senegal

RS3PE syndrome is a rare inflammatory rheumatism affecting mainly elderly subjects. We report a peculiar observation in a fifty-two-year-old female patient who was admitted for migrating edema (that begun on the feet and then move to the back of the hands) associated with polyarthritis. The diagnosis of RS3PE was evoked in accordance with McCarty’s criteria. 12-month treatment with low doses of corticosteroids has led to a favorable clinical evolution. Le syndrome RS3PE (remitting symmetrical seronegative synovitis with pitting edema) est un rhumatisme inflammatoire rare touchant électivement le sujet âgé. Nous en rapportons une observation atypique chez une patiente de cinquante-deux ans admise pour des œdèmes migratoires (débutant au niveau des pieds puis aux dos des mains) associées à une polyarthrite. Le diagnostic de RS3PE a été retenu en accord avec les critères de McCarty. Sous traitement à base de corticoïde à faible dose administrée pendant douze mois, l’évolution clinique a été favorable

Verification and Validation of D2FD Method

International audience—D2FD (Data to Fuzzy-DEVS) method provides a solution for the problem of system inference. This method is well designed and implemented as an available and dedicated plug-in within the process mining framework (ProM). This plug-in is also integrated with the simulation tool SimStudio. However, the last step of the process of inferring models and simulations, which is verification and validation, is missing. This paper proposes a new paradigm of verification and validation in system inference. The case study uses the method of comparing with other models as the main validation technique. Based on the same data source from the Dutch Employee Insurance Agency, it attempts to compare the previous results with other studies

Une Recette Utilisée dans le Traitement Traditionnel des Troubles du Sevrage des Enfants au Mali

Combretum lecardii est traditionnellement utilisé contre les troubles du sevrage des enfants au Mali. Le présent travail avait comme objectif de recenser les données de sécurité, d’efficacité et de qualité de Combretum lecardii. Les informations sur Combretum lecardii ont été collectées en consultant des  livres, des sites et des moteurs de recherche tels que Google, Google scholar, Prota etc. Les résultats ont montré que Combretum lecardii contient des flavonoïdes, tanins et de composées à génines stéroïdiques. La poudre de feuilles de Combretum lecardii possédait des poils tecteurs, des fibres, du xylème, des grains d’amidon, des cristaux d’oxalate de calcium, du parenchyme et des fragments d’épiderme avec stomates. Traditionnellement, Combretum lecardii est utilisé contre les troubles du sevrage et d’autres pathologies. Pharmacologiquement, les activités antitussive, antibactérienne, antidiarrhéique et antalgique de Combretum lecardii ont été retrouvées. Ces résultats peuvent aider à la mise au point d’un médicament traditionnel amélioré à base de Combretum lecardii pour la prise en charge des troubles du sevrage de l’enfant.   Combretum lecardii is traditionally used against child weaning disorders in Mali. The objective of this work was to identify the safety, efficacy and quality data of Combretum lecardii. Information on Combretum lecardii were collected through books, sites and search engines such as Google, Google scholar, Prota etc. The results showed that Combretum lecardii contains flavonoids, tannins and steroidal genin compounds. Combretum lecardii leaf powder had covering trichomes, fibers, xylem, starch grains, crystals of calcium oxalate, parenchymatous cells and epidermis fragments with stomata. Traditionally, Combretum lecardii is used against weaning disorders and other pathologies. Pharmacologically the antitussive, antibacterial, antidiarrheal and analgesic activities of Combretum lecardii were found. These results can be helpful for developing an improved traditional medicine based on Combretum lecardii for the management of child weaning disorders
