Signal and Image processing

Robust estimation of structured scatter matrices in (mis)matched models

Covariance matrix estimation is a ubiquitous problem in signal processing. In most modern signal processing applications, data are generally modeled by non-Gaussian distributions with covariance matrices exhibiting a particular structure. Taking…

Modified Sparse Subspace Clustering for Radar Detection in Non-stationary Clutter

Detecting targets embedded in a noisy environment is an important topic in adaptive array processing. In the traditional statistical framework, this problem is addressed through a binary hypothesis test, which usually requires the estimation of side…

Modelling a redefined architecture for concentrated photovoltaic power plant

The whole research projects that concern the concentrated photovoitaic (CPV) are systematically about the yield improvement of the cell. The positioning of the work presented here is at the cell interconnections for achieving a stable DC bus to…

Conception and command of a three phase series resonant converter under unbalanced condition

This paper deals with the design of a 3-phase, high frequency series resonant DC-DC converter. If the converter is perfectly balanced, the third harmonic and its multiples are canceled and the input and output current ripples are greatly reduced…

Traveling wave piezoelectric transformer for multi-level insulated gate-driver power supply

The traveling-wave piezoelectric transformer (TWPT) is a new topology of piezoelectric transformer providing a multi-phases system of voltages at its output. The inherent galvanic insulation of piezoelectric transformers makes them particularly…

Dual control on structure and magnetic properties of Mg ferrite: Role of swift heavy ion irradiation

Effect of swift heavy ion irradiation on MgFe2O4 (annealed at 450 °C/3 h) sample prepared by a sol–gel auto-combustion procedure has been studied. Single phase samples were irradiated with 120 MeV 28Si9+ with ion fluence: 1 × 1011, 1 × 1012, and 1 ×…
