Collinearly placed patch antenna arrays, printed on high permittivity dielectric substrates, suffer from an unwanted inter element coupling due to strong surface waves. A new shaped Defected Ground Structure (DGS) is proposed to suppress such waves in between elements. A low dimensional μ shaped DGS is carved out in between two E-plane patch antenn...
De même que les technologies numériques ont profondément modifié la manière dont se pratiquent les humanités, la réalité virtuelle promet d’être un outil de travail incontournable dans le futur. Cette thèse s’intéresse aux potentiels de l’immersion en réalité virtuelle pour les historiens et les archéologues en proposant une méthode de travail adap...

The marine current turbine (MCT) is becoming more and more popular to produce eco-friendly electricity.However, its performance is negatively affected by MCT imbalance fault. In this paper, an integration faultdetection method using stator voltage for MCT is proposed. This method uses an integration way to detect theimbalance fault. The proposed me...
A compact and conformal cylindrical antennafor IoT sensor applications is presented. Plastronicsdevelopment using Laser Direct Structuring (LDS) process iscarried on to optimize the space occupied by the antenna.Specific LDS-compatible polycarbonate (PC) thermoplastic isused as a substrate. The dipole antenna stands on the outersurface of a 17 mm h...
This paper presents the design, simulation and prototypingof a 2-bit dual linearly-polarized transmitarray antenna(TA) for 5G millimeter-wave point-to-point backhauling radiolinks at D-band (130 - 174.8 GHz). The flat lens consists of asquare array with 1600 unit cells arranged on a 40×40 elementregular grid. This array is based on a printed circui...
Fuel assembly bow in a nuclear core is a topic of interest for safety and performance of power plants, due to the potential increase of the drop time of rod cluster control assemblies, and potential difficulties to handle the assemblies. It may as well lead to quadrant power tilts or to early wear of the fuel rods. Some advanced analyses are still ...
In this paper, a battery-powered Internet of Things assisting Cognitive Radio (CR-IoT) network is considered. In CR-IoT network, a set of IoT End Nodes (ENs) are assumed to cooperatively sense the channel. Each EN performs a Spectrum Sensing (SS) and reports its decision to a Fusion Center in order to reach the decision on the PU status. Such monit...
In the automotive industry, the design process is both costly and time-consuming. This research focuses on improving the design process by mainly reducing time while producing more robust vehicles. Vehicle development is based on simulation; thus, the design process is referred to as simulation-aided design. Engineering design is highly collaborati...
