Contribution to the semantic characterization of web service by non-functional properties for the selection and composition of services

This paper suggest an engineering oriented vision of services composition where the composition has its own life cycle and can be reused and adapted to operating contexts. We will present a specific model that enable the enrichment of ontology of services by non-functional properties corresponding to the quality of service, user profiles, preferences and security protocols of access to information corresponding to user profiles

Complication rare de la coloscopie chez un patient sous anticoagulant: hemopéritoine par rupture d’un hématome sous capsulaire de la rate, cas clinique

La coloscopie à visée diagnostique et/ou thérapeutique est un examen invasif fréquemment pratiquée de nos jours. La perforation colique et l'hémorragie digestive en sont les principales complications. La survenue d'un  hémopéritoine par rupture d'un hématome sous-capsulaire splénique est une complication extrêmement rare et potentiellement mortelle de la coloscopie. Un traumatisme splénique minime passé inaperçu et la prised'anticoagulant en sont des facteurs favorisants. Nous présentons le cas d'une rupture d'un hématome sous-capsulaire de la rate après une coloscopie, survenue chez un patient de 70 ans porteur d'une valve mitrale mécanique sous acénocoumarol à dose hypocaogulante. La nécessité d'obtention d'une anti coagulation rapidement efficace et l'instabilité hémodynamique avaient justifiée la réalisation d'une splénectomie. L'évolution était favorable. A travers cette observation clinique nous discutons les mécanismes et les modalités de prise en charge devant cette complication

Global solutions and self-similar solutions of semilinear wave equation

International audienceWe prove existence, uniqueness and regularity results for the global solutions of the semilinear wave equations. In particular, we show existence of regular self-similar solutions. Also, we build some finite-energy asymptotically self-similar solutions

Global solutions and self-similar solutions of nonlinear wave equations

National audienceWe prove some results about existence, uniqueness and regularity properties of global solutions of the nonlinear wave equations. In particular we show existence of regular self-similar solutions. We build also a family of finite energy solutions which converge asymptotically to self-similar solutions.

Functional Analysis-H=W Musielak spaces framework, by Youssef Ahmida, Alberto Fiorenza and Ahmed Youssfi, communicated on 13 December 2019

Wc give a sufficient structural condition on the Musielak functions for the Meyers-Scrrin theorem to hold in Musielak spaces. Wc unify and extend some density results of smooth functions in Orlicz Sobolcv spaces as well as in variable exponent Sobolev spaces

The SALTMED model calibration and validation using field data from Morocco

The objective of this study was to calibrate and validate the SALTMED model using field data of three growing seasons of quinoa (Chenopodium quinoa Willd.), chickpeas (Cicer arietinum) and sweet corn (Zea mays Saccharata) which were grown in the south of Morocco and subjected to six treatments of deficit irrigation with treated wastewater. The calibration focussed primarily on soil moisture related to quinoa in the field, measured yield and dry matter. The validation process of biomass production was based on use of the calibrated photosynthesis efficiency value of the control treatment. Plant parameters such as plant height and rooting depth, duration of each growth stage, sowing date, harvesting date, harvest index and leaf area index were based on field measurements and records. Crop coefficients Kc, Kcb, Fc were based on FAO56 paper. Soil parameters such as water retention curves were based on laboratory measurements. Initial soil water content and salinity were based on measurements either in the laboratory or in the field. Fine tuning of some crop and soil parameters was carried out in order to obtain a good calibration. Following successful calibration and validation, the SALTMED model proved its ability to predict soil moisture, yield and total dry matter for three growing seasons under several deficit irrigation strategies using treated wastewater. The model showed a very good agreement between the observed and simulated data, as well as being able to reveal the same difference between deficit irrigation strategies in terms of measured yield and total dry matter
