Bilal Al-Taki will present his work: On some heteregenous models in fluids dynamics, Monday the 19th, 14:00 in the LAMA Lab. Thomas Lachand-Robert room.

Summary:
This thesis is devoted to the mathematical analysis of some heterogeneous models raised by uid mechanics. In particular, it is devoted to the theoretical study of partial dierential equations used to describe the main models that we present in the following. Firstly, we are interested to study the motion of a incompressible newtonien uids in a basin with degenerate topography. The mathematical model studied derives from 3dincompressible Navier-Stokes equations. We are interested to prove that the Cauchy problem associated is well posed. The second part in my thesis is devoted to study a model that arises from dispersive Navier-Stokes equations (that includes dispersive corrections to the classical compressible Navier-Stokes equations). Our model is derived from the last model assuming that the Mach number is very low. The obtained system is called ghost eect system, which is so named because it cannot be derived from the Navier-Stokes system of gas dynamics, while it can be derived from kinetic theory. The main goal of this part is to extend a result concerning the local existence of strong solution to a global in time existence of weak solutions. Finally, we are interested to prove certain functional inequalities who have noticeable interest in solving mathematical systems linked to uid mechanics.

Symposium on Geometry Processing Software Award

The generic and collaborative C++ open source library for Digital Geometry programming DGtal received the « Symposium on Geometry Processing Software Award » 2016 !

Congratulations to Jacques-Olivier Lachaud, initiator of the project and Roland Denis, important contributor, both winners of the prize !

This prize rewards an open-source high quality software or library around the thema of shape geometry processing.

Issued from a collaboration betwwen the LAMA and the LIRIS Labs, the collaborative project DGtal is now a standard in the international discrete geometry research field.
