The numerical solution of most fluid mechanics problems usually needs such a fine mesh that the associated computational times become non-negligible parts in any design process. In order to coupleâ€¦ (More)

This paper presents the solution of coupled radiative transfer equation with heat conduction equation in complex three-dimensional geometries. Due to very different time scales for both physics, theâ€¦ (More)

The computation of fluid mechanics problems usually leans on a discretization of the Navier-Stokes equations which has to be so fine that the dimensions of the linear systems to be solved are veryâ€¦ (More)

This paper deals with the estimation of optical property distributions of participating media from a set of light sources and sensors located on the boundaries of the medium. This is the so-calledâ€¦ (More)

We consider the resolution of an inverse problem for the identification of some reduced nonlinear diffusive models. The modal identification method is dealt with along with a gradient-typeâ€¦ (More)

In optical tomography, the optical properties of the medium under investigation are obtained through the solution of an inverse problem where some light is injected on a boundary and the measurementâ€¦ (More)

The inverse problem of optical tomography is ill-posed. Usually, the zeroâ€“order Tihonov regularization penalization is used. Though this method may be efficient in special circumstances, the use ofâ€¦ (More)
