Inclusions différentielles et problèmes variationnels

In this thesis we deal with three different but connected questions. Firstly (cf. Chapter 2) we make a systematic study of the generalized notions of convexity for sets. We study the notions of polyconvex, quasiconvex and rank one convex set. We remark tha ...

The surface Laplacian operator of the potentials on a bounded volume conductor has a unique inverse

In the discussion on the use of the surface Laplacian (SL) of the distribution of bioelectric potentials on the body surface, the question remained open whether a complete specification of the SL of the potential over the surface bounding a volume conducto ...

Signal processing techniques based on singular value decomposition applied to modulated ECH experiments

Jean-Marc Moret, Adriano Manini

The analysis and interpretation of perturbative modulated electron cyclotron heating (MECH) discharges for power deposition localization using different diagnostics, such as electron cyclotron emission (ECE) and soft x-ray (SXR) measurements, are presented ...

Inverse closed-loop power control for CDMA wireless systems

Ali H. Sayed

In this work, two algorithms for closed loop power control in CDMA wireless systems are proposed. These algorithms aim to minimize the power control error by predicting the inverse of the channel fading: For this purpose, a channel fading prediction scheme ...

Spatiotemporal EEG analysis and distributed source estimation in presurgical epilepsy evaluation

Olaf Blanke

In the attempts to localize electric sources in the brain on the basis of multichannel EEG and/or MEG measurements, distributed source estimation procedures have become of increasing interest. Several commercial software packages offer such localization pr ...

Fast triangular factorization of the sum of quasi-Toeplitz and quasi-Hankel matrices

Ali H. Sayed

The literature contains several recent fast algorithms for the triangular factorization of strongly regular Toeplitz-plus-Hankel matrices. In this paper we study the rather more general sum of quasi-Toeplitz and quasi-Hankel matrices, both Hermitian and no ...

Structure and arithmetic complexity of products and inverses of Toeplitz matrices

Martin Vetterli

We derive a formula for the product of two Toeplitz matrices that is similar to the Trench formula for the inverse of a Toeplitz matrix. We then derive upper and lower bounds for number of multiplications required to compute the inverse or the product of T ...
