Secrets of image denoising cuisine

Digital images are matrices of equally spaced pixels, each containing a photon count. This photon count is a stochastic process due to the quantum nature of light. It follows that all images are noisy. Ever since digital images have existed,…

The Optimal Aspect Ratio for Piecewise Quadratic Anisotropic Finite Element Approximation

Mesh adaptation for finite element approximation is a procedure used in numerous applications. The use of thin and long anisotropic triangles improves the efficiency of the procedure. When piecewise linear finite elements are used, the aspect ratio…

Shape, sizing optimization and material selection based on mixed variables and genetic algorithm

In this work, we explore simultaneous designs of materials selection and structural optimization. As the materials election turns out to be a discrete process that finds the optimal distribution of materials over the design domain, it cannot be…

Méthodes de Galerkin non linéaires en discrétisation par éléments finis et pseudo-spectrale. Application à la mécanique des fluides

For computing the solution of partial differential equations in fluid mechanics and physics, some new numerical schemes, the nonlinear Galerkin methods, mo­ tivated by concepts of the dynamical systems theory were developped by Marion and Temam. In…
