Solution de l’équation de Poisson dans un domaine bidimensionnel par la méthode des éléments finis
Revue des Énergies Renouvelables, 2013 Ce travail présente une modeste contribution sur le domaine des éléments finis. On a essayé de résoudre l’équation de Poisson avec les conditions aux limites de type Dirichlet dans un domaine quelconque bidimensionnel simplement connexe.

Macromolecular Symposia, Volume 413, Issue 3, June 2024.Abstract Vertical green structures (VGS) increase green spaces in compact urban areas offering benefits as an improved thermal insulation of the building envelope, and a decrease of the Urban Heat Island effect. Efficient species selection and quantitative evaluation of species’ reaction to hygro‐thermal variations are needed to optimize VGS benefits ...

The resilience of the pork supply chain to a food safety outbreak: The case of dioxins
Risk Analysis, Volume 44, Issue 4, Page 785-801, April 2024.Abstract Food supply chains are constantly challenged by food safety hazards entering the chain. The ability of the supply chain to provide safe food within a reasonable time after such a food safety threat or shock can be investigated with the concept of resilience using food safety as an indicator.
