Bounded Nash type controls for uncertain linear systems

This paper deals with multicriteria controls for systems coping with polytopic uncertainties. The proposed controls are inspired by a Nash strategy for exactly known systems, reformulated as a nonconvex coupling between Semi-Definite Programming…

Covariance Structure Maximum-Likelihood Estimates in Compound Gaussian Noise: Existence and Algorithm Analysis

Recently, a new adaptive scheme [1], [2] has been introduced for covariance structure matrix estimation in the context of adaptive radar detection under non Gaussian noise. This latter has been modelled by compound-Gaussian noise, which is the…

Image storage through gray-scale encoding of second harmonic signals in azo-dye copolymers

The authors investigated the optical data and image storage in polymeric materials functionalized with azo-dye molecules. Thin films are initially poled to generate a spatially homogeneous second harmonic signal. The information is locally inscribed…
