— The development of search engine for similar images stays yet a scientific challenge. Since every image is represented by one or more vectors, the research stage becomes very hard. To raise these difficulties, we suggest inserting a search engine based on multiple representations of images where every image will be represented by three vectors that are… (More)

Abstract In this paper, we give an a posteriori error estimates with constitutive law for some obstacle problem. The error estimator involves some parameter ε appeared in some penalized… (More)
— A new technique for the implementation of cell-centered finite volume schemes is proposed. It is based on an equivalence between these schemes and the non-conforming Crouzeix-Raviart finite element approximation. Though the implementation somewhat increases the number of unknowns, it brings two significant advantages that make it attractive. On the one… (More)
The paper deals with the existence of solutions of some parabolic bilateral problems approximated by the renormalized solutions of some parabolic equations.
