Estimation de fonctions géométriques et déconvolution
The presented work is divided into three parts. At first, we show that the formalism of model selection allows to bound the decay rate of the estimation error of a... -
Near-field data compression for the far-field computation in FDTD
This paper presents a technique to compress the near-field data required to compute the radiated fields using FDTD. This technique is applied to the study of a UWB... -

Seismo-electromagnetic conversions in porous media
A seismic wave passing through a uid-containing porous medium creates a relative motion between the uid and solid phases. By moving the excess ions in the electrical... -

Decomposition and detection of geometric structures in imagery
In this thesis, we investigate the different image decomposition models wich permit to separate an image into two components: the structures (or objects) and the... -

Adaptive wavelet estimation of a density from mixtures under multiplicative c...
In this paper, a mixture model under multiplicative censoring is considered. We investigate the estimation of a component of the mixture (a density) from the... -
A general result on the performance of the wavelet hard thresholding estimato...
In this note, we consider the estimation of an unknown function $f$ for weakly dependent data ($\alpha$-mixing) in a general setting. Our contribution is theoretical:... -
A note on wavelet estimation of the derivatives of a regression function in a...
We investigate the estimation of the derivatives of a regression function in the nonparametric regression model with random design. New wavelet estimators are... -
