Modeling by the finite element method of acoustic radiation in waveguides lined with locally or non locally reacting absorbent materials in the prese…
2011
Our concern in this work is the problem of acoustic propagation in guides lined with locally or non locally reacting materials with the presence of mean fluid flow. In several industrial systems such as aircraft jet engines, mufflers exhaust and ventilation systems, noise is mostly channeled outside by guides of more or less complex geometries. A study of waveguides makes it possible to predict and understand the physical phenomena such as refraction, convection, absorption and wave attenuation. In waveguides studies, guides are often considered infinitely long to get rid of some phenomena (reflection for example) at their ends. Solving the problem of acoustic propagation in infinite guides…
Semantic and Multi-scale BIM/CIM/LIM
2019
Compliance checking for building models, cities and territories involve formalizing a set of model schema knowledge and constraint. The objective of our study is to propose: an information model to federate heterogeneous data sources describing an urban area (building and building environment) along with a method for formally specifying of urban rules. The overall goal we pursue is to be able to query and to verify data against different regulations and/or requirements. The purpose of this article is to describe our approach for interoperability among different data sources (e.g. IFC, CityGML) thus creating a consistent description of an urban area.
Une architecture générique de Systèmes de recommandation de combinaison d'items : application au domaine du tourisme
2011
This thesis gives a generalization of the recommendation principle of recommender systems. Instead of considering a recommendation as an item, it is considered as a combination of several items following a given pattern. A recommendation of a unique item is then a particular case of this type of recommendation. The proposed recommender system framework is based on an architecture derived from work in adaptive hypermedia systems. Three layers are defined: a semantic layer, a user layer and an intelligence layer. The semantic layer consists of two sub-layers, a sub-layer modeling the content according to the general knowledge of the domain and a sub-layer modeling the content according to the…
Semantic-aware news feeds management framework
2010
In the Web, RSS and Atom (feeds) are probably the most popular and highly utilized XML formats which allow web communities, publishing industries, web services, etc. to publish and exchange XML documents. In addition, they allow a user to consume data/information easily without roaming from site to site using software applications. Here, the user registers her favorite feed providers; and each provider sends the list of news items changed since the last download. However, registering a number of feed sources in feed aggregators cause both heterogeneity and information overloading problems. Besides, none of the existing RSS/feed aggregators provide an approach that integrates (merges) feeds …
Qualité du Sol - Méthode pour extraire directement l'ADN d'échantillons de sol (Norme française - internationale)
2012
La présente Norme internationale spécifie une méthode pour extraire directement l'ADN d'échantillons de sol en vue d'analyser la structure globale et l'abondance des communautés microbiennes du sol en utilisant des techniques de PCR. Cette méthode est principalement destinée aux sols agricoles et forestiers. Cette méthode peut ne pas être appropriée aux sols riches en matières organiques (par exemple sols de tourbières) ou aux sols très pollués par des polluants organiques ou des métaux lourds. L'extraction directe de l'ADN d'échantillons de sol fournit des informations précieuses sur l'abondance et la structure des communautés microbiennes qui sont des paramètres clés pour estimer la biodi…
