QUALITY IN TERMS OF COST EFFICIENCY

The studies based on using selective research are one of the maininstruments in the strategy building process at the managing level of academic facilities and collecting the data in the most effective way possible is one of the main problems that this kind of studies can arise.A way of solving this problem could be collecting the necessary dataonline, which implies human and financial resources a lot reduced compared to the classical way. Based on selective research, conducted among students, it has been tested the quality of the data collected online, by comparing them to the ones collected by face-to-face interviews.The studies that use selective research, conducted in the academicenvironment, in student collectivities, alumni, future possible students, the employers that might need the university’s graduates etc., are quite suitable for using the online collecting method of the data, due to the characteristics of the analyzed collectivities

Hydro-socio-economic implications for water management strategies: the case of Roussillon coastal aquifer

In many Mediterranean coastal areas, agriculture, drinking water supply, tourism and industry strongly depend on the available groundwater resources. As a result of the significant economic development during the last three decades along the coast, abstractions from coastal aquifers have increased tremendously, frequently leading to overexploitation and saltwater intrusion. Geological, hydrogeological and socio-economical studies as a multidisciplinary approach on a coastal Mediterranean aquifer- the Roussillon - have been carried out in order to design effective water management strategies on areas sensitive to seawater intrusion risk. Geology provides geometry and architecture of the different aquifers, hydrogeology assess the seawater intrusion risk while socio-economic study includes consulting the stakeholders with the aim of suggesting water management and policy option acceptable to the majority of population. This paper then highlights the economic interests at stake, diversity of viewpoints expressed by stakeholders and political dimension of the issue, which are likely to be encountered for all similar situations on both sides of the Mediterranean Sea.GESTION DE L'EAU;STRATEGIE;HYDROGEOLOGIE;SOCIOLOGIE;ECONOMIE;MER MEDITERRANEE;ROUSSILLON

Retina-Enhanced SURF Descriptors for Semantic Concept Detection in Videos

International audienceThis paper proposes to investigate the potential benefit of the use of low-level human vision behaviors in the context of high-level semantic concept detection. A large part of the current approaches relies on the Bag-of-Words (BoW) model, which has proven itself to be a good choice especially for object recognition in images. Its extension from static images to video sequences exhibits some new problems to cope with, mainly the way to use the added temporal dimension for detecting the target concepts (swimming, drinking...). In this study, we propose to apply a human retina model to preprocess video sequences, before constructing a State-Of-The-Art BoW analysis. This preprocessing, designed in a way that enhances the appearance especially of static image elements, increases the performance by introducing robustness to traditional image and video problems, such as luminance variation, shadows, compression artifacts and noise. These approaches are valuated on the TrecVid 2010 Semantic Indexing task datasets, containing 130 high-level semantic concepts. We consider the well-known SURF descriptor as the entry point of the BoW system, but this work could be extended to any other local gradient based descriptor

Analyse de trajectoires pour l'indexation sémantique des vidéos à grande échelle

National audienceL'indexation sémantique automatique de grandes collections vidéo est un problème complexe qui ne peut se limiter à l'analyse de mots clefs saisis par les utilisateurs. L'extraction de descripteurs spatiaux et temporels à partir du contenu est devenu indispensable pour appréhender la grande richesse des contenus. Cependant, le coût de calcul associé à l'extraction de descriptions temporelles est bloquant et les systèmes actuels se limitent souvent au traitement de l'information spatiale. Dans ces travaux, nous proposons une méthode d'analyse de trajectoires de points caractéristiques. Ses besoins en ressources de calcul sont faibles et s'adaptent facilement à de grandes collections vidéo. Partant d'une description des trajectoires de points d'intérêt utilisant l'analyse du flot optique, une batterie de descripteurs basés sur les modèles Sac de Mots sont calculés pour représenter les vidéos. L'approche est évaluée dans le contexte difficile du challenge TRECVid Semantic INdexing (SIN)

SIMULATION DES CHAMPS ELECTRIQUES DANS LES CONFIGURATIONS TYPES D'UN MOTEUR SYNCHRONE DE TRACTION– VALIDATION PAR L'EXPERIMENTATION DES SEUILS D'APPARITION DE DECHARGES PARTIELLES

International audienceLa simulation des champs électriques est un outil de plus en plus utilisé afin d'estimer le risque de voir apparaitre ou non des décharges partielles dans les moteurs électriques de traction. Deux modélisations ont été effectuées. Une première simule les champs électriques maximaux obtenus entre fils de cuivre nus. Elle permet une première estimation des risques avant l'application des matériaux isolants. La seconde simule les champs électriques de configurations types de moteurs en fonction de la température. Le logiciel Comsol® est exploité et combiné avec l'utilisation de la loi de Paschen modifiée par Dunbar. Cette modélisation permet d'obtenir des résultats très proches des mesures sur motorettes (Norme IEEE 117 1974) et ainsi d'évaluer les risques sur ces supports

Prevention of cardiovascular disease in patients with familial hypercholesterolaemia: the role of PCSK9 inhibitors

Familial hypercholesterolaemia is an autosomal dominant inherited disorder characterised by elevated low-density lipoprotein cholesterol levels and consequently an increased risk of atherosclerotic cardiovascular disease (ASCVD). Familial hypercholesterolaemia is relatively common, but is often underdiagnosed and undertreated. Cardiologists are likely to encounter many individuals with familial hypercholesterolaemia; however, patients presenting with premature ASCVD are rarely screened for familial hypercholesterolaemia and fasting lipid levels are infrequently documented. Given that individuals with familial hypercholesterolaemia and ASCVD are at a particularly high risk of subsequent cardiac events, this is a missed opportunity for preventive therapy. Furthermore, because there is a 50% chance that first-degree relatives of individuals with familial hypercholesterolaemia will also be affected by the disorder, the underdiagnosis of familial hypercholesterolaemia among patients with ASCVD is a barrier to cascade screening and the prevention of ASCVD in affected relatives. Targeted screening of patients with ASCVD is an effective strategy to identify new familial hypercholesterolaemia index cases. Statins are the standard treatment for individuals with familial hypercholesterolaemia; however, low-density lipoprotein cholesterol targets are not achieved in a large proportion of patients despite treatment. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been shown to reduce low-density lipoprotein cholesterol levels considerably in individuals with familial hypercholesterolaemia who are concurrently receiving the maximal tolerated statin dose. The clinical benefit of PCSK9 inhibitors must, however, also be considered in terms of their cost-effectiveness. Increased awareness of familial hypercholesterolaemia is required among healthcare professionals, particularly cardiologists and primary care physicians, in order to start early preventive measures and to reduce the mortality and morbidity associated with familial hypercholesterolaemia and ASCVD
