We consider two parallel-in-time approaches applied to a (reaction) diffusion problem, possibly non-linear. In particular, we consider PFASST (Parallel Full Approximation Scheme in Space and Time) and space-time multigrid strategies. For both approaches, we start from an integral formulation of the continuous time dependent problem. Then, a collocation form for PFASST and a discontinuous ...

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO013.
Recent years have seen the rapid growth in interest towards fractional calculus. Fractional calculus plays an important role in modelling anomalous diffusion phenomena, however closed-form analytical solutions of such equations are rarely available, hence numerical estimates are needed. In this thesis we consider various fractional diffusion equations (FDEs), where different fractional ...

Mémoire de master : Haute Ecole Arc Conservation-Restauration, 2021.
Ce mémoire est dédié à l’étude et au traitement d’une mosaïque paléochrétienne déposée, supposée être originaire du nord de la Syrie. Sa provenance incertaine est liée au contexte de dépose illégale probablement réalisée à des fins lucratives. La mosaïque, découverte en 2012 dans un dépôt, présente un état de conservation précaire. Les tesselles composant le...
