Spectral and spectral-element methods for the 2D and 3D elastodynamics equati...
In this thesis, we study spectral and spectral-element methods for the 2D and 3D elastodynamics equations in heterogeneous media. Details are given about the... -
Binary systems of compact objects : neutron stars, strange quark stars and bl...
The detection of gravitational waves by ground-based laser interferometers, such as VIRGO or LIGO, or in space with LISA will be greatly facilitated by having a prior... -
Numerical Study of Non-linear Dispersive Partial Differential Equations.
Numerical analysis becomes a powerful resource in the study of partial differential equations (PDEs), allowing to illustrate existing theorems and find conjectures. By... -
Contribution to numerical study of rotating flows with walls. An application ...
The Taylor-Couette system, consisting of shear flow between differentially rotating concentric cylinders, has been investigated experimentally and numerically in great... -
Fatigue behavior under vibration environment : Taking into account the plasti...
Mechanical structures are often subjected to random vibrations due to external forces (forces, acceleration...). Improving the safety of structures and reducing... -
Empirical Mode Decomposition: Contribution to Mathematical Modeling and Appli...
The EMD technique is a new tool for representing non linear and non-stationary signal as a sum of components called Intrinsic Mode Functions (IMF). The EMD... -
Transport de neutrinos dans les supernovas gravitationnelles
This thesis is about numerical simulations of core collapse supernovae, with an accent on the neutrino transport problem. Neutrinos play a central role in the...
