The subject of this thesis is the 2D numerical modeling of an SiGe HBT (Heterojunction Bipolar Transistor) using the SILVACO-TCAD software. A simulation of the technological process was first adapted and carried out, and ...

In recent years, a significant number of studies have focused on microstrip antennas and dielectric resonator antennas because of their many advantages. Two main components formed the body of this thesis. The objective of ...

In this dissertation, we used chemical spray pyrolysis method for the growth of pristine, annealed, and magnesium (Mg) doped tin dioxide (SnO2) thin films, for their application in the detection of toxic gases. The synthesis ...

This work was devoted to the study of the characteristics of periodic structures of artificial materials by the application of numerical methods. Our interest was focused on the study of multilayer structures with ...

The main goal of the Voice Activity Detection (VAD) techniques is to distinguish between voiced regions and silent intervals in an audio communication. This step is crucial in most speech processing systems such as mobile ...

We present an analytical model for the I-V characteristics of AlGaN/GaN and AlInN/GaN high electron mobility transistors (HEMT). Our study focuses on the influence of a GaN capping layer, and of thermal and self-heating ...

In this thesis we consider the study and the design of new structures of refractive index sensors based on two-dimensional photonic crystals, and in particular their exploitation in detection domain. The proposed structures ...

Our work involves the design and rigorous evaluation of a new design of Metal Oxide Semiconductor (SMO) gas sensor with different shapes and sizes, in order to evaluate the most efficient implantation geometry in terms of ...

The objective of this thesis mainly concerns the development of fault tolerant control laws for delayed nonlinear systems. Robust methodologies are designed in the context of the unknown inputs occurring in the control ...
