Report

A review of the use of optimal transport distances for high resolution seismic imaging based on the full waveform

Autor: Métivier, Ludovic, Brossier, Romain, Kpadonou, Félix, Messud, Jérémie, Pladys, Arnaud

We consider the high-resolution seismic imaging method called full-waveform inversion (FWI). FWI is a data fitting method aimed at inverting for subsurface mechanical parameters. Despite the large adoption of FWI by the academic and industrial commun

Shape and anisotropy optimization by an isogeometric-polar method

Autor: Kpadonou, Félix

Publikováno v: Optimization and Control [math.OC]. Université Paris-Saclay, 2017. English. ⟨NNT : 2017SACLV048⟩

This thesis tackles the problem of the shape and anisotropy optimization of shell structures. The first part of this work focuses on the analysis of the shell model. The mechanical behavior of the structure is described using the Naghdi’s shell mod
