In this thesis, we considered the tracking control of a class of multi-input multioutput (MIMO) nonlinear uncertain systems with faults. At the beginning, general ideas of adaptive fault-tolerant with the best researchers ...

For the conception and the simulation of the microwave integrated circuits, it’s important to make up a sample theoretical model that takes into account all the effects which happen at the main constituting element of ...

In this thesis we have discussed the estimation of the multipath fast fading channel in OFDM systems. Channel estimation requires a large number of pilots, which reduces the number of subcarriers dedicated to the useful ...

Phoxonic structures (also called phononic-photonic) consist of a periodicity in the refractive index and acoustic impedance in a systematic way and confine acoustic and electromagnetic waves.They lead to new acousto-optical ...

Dielectric barrier discharges operating at atmospheric pressure are generally filamentary type discharges, but under particular conditions, they can be homogeneous. The present work consists, on the one hand, in developing ...

2D CPh waveguides play an important role in the realization of very dense integrated optical circuits. They are considered appropriate structures for the creation of optoelectronic processors because of their low losses ...

During the photovoltaic conversion of the solar collector, a heat is generated, what will increase the temperature of the photovoltaic cell and will cause a fall of its efficiency. This phenomenon is due to the part of ...

The theme of our thesis is the study, design, and realization of the first 406 MHz Algerian beacon by the doctoral student Ali Srihen Billel digital transmission associated with a 406 Mhz mobile frame decoder. The ...

This thesis deals with two principle axes : • Statistical characterization • And dynamical characterization of pn and Schottky (Al/mc-Si) diodes. Statistical characterization is done through experimental ܫሺܸሻ and ܥሺܸሻ ...

The main purpose of this thesis was to study, modeling and design of printed antennas. Three main parts have formed the body of this thesis. In the first part, we have developed two methods for modeling a rectangular ...
