Titre: Modeling and Simulation of an industrial automaton (Oil shipping pump) Auteur(s): abimouloud, Adel.; KHERCHOUCHE, SOUFIANE; GHERIBI, TAREK Résumé: The research we conducted during the period of this thesis aims to design a computer application for HMI panel to control a pump station unit via the virtual industrial programmable logic controller that reproduces by simulation the operation of the real automation at lower cost and without risk. The purpose of our application is to make it easier for the operator to work, to ensure material and personal safety, with the least amount of manpower, and to avoid pump outages and shipping delays with the lowest cost possible. As part of our project, we needed automation and supervision software. It is in this sense that we decided to use the new Totally Integrated Automation (TIA) software, which combines both SIMATIC STEP 7 and WINCC. Description: Instrumentations and systems

Titre: Study and Development of Wearable Textile Antennas with Metamaterials and EBG Structures Auteur(s): CHEBBARA, Fouad; MESSATFA, TAREK Résumé: In recent years, wearable textile antennas have gained significant attention for their seamless integration into clothing, offering considerable benefits for wireless communication, healthcare, and body-area networks. These antennas are designed to be flexible, lightweight, and comfortable while maintaining high radiation efficiency and gain. However, a key challenge is to enhance antenna performance without compromising wearability, especially under mechanical deformations such as bending and stretching. This PhD thesis presents the design, development, and analysis of a novel, compact, tri-band, apple-shaped wearable textile antenna inspired by metamaterials and backed by a novel Uniplanar Compact Electromagnetic Bandgap (UC-EBG) structure. The antenna is fed using a Coplanar Waveguide (CPW) and is designed for Wireless and Medical Body Area Network (WBAN/MBAN) applications. The proposed printed textile antenna operates at three frequency bands: 2.45 GHz for Wireless Local Area Networks (WLAN), 3.5 GHz for 5G New Radio (NR), and 5.8 GHz for Industrial, Scientific, and Medical (ISM) bands. A novel UC-EBG structure is used as a ground plane to minimize the effect of antenna back radiation on the human body while enhancing antenna performance. Furthermore, metamaterial-based triangular complementary split-ring resonators (TCSRRs) are incorporated into both the antenna and UC-EBG structure, resulting in a compact textile antenna with overall dimensions of 0.41λg × 0.41λg × 0.029λg. The use of jeans fabric as the antenna substrate provides an optimal balance of flexibility, durability, elasticity, and deformation resistance, ensuring seamless integration into clothing. The UC-EBG unit cell is analyzed using the reflection phase, suspended line, and dispersion diagram methods. The integration of the UC-EBG structure resulted in a iii99% reduction in Specific Absorption Rate (SAR) values, achieving values below the safety limits established by regulatory standards in America and Canada (1.6 W/kg for 1g of tissue) and in Europe (2 W/kg for 10g of tissue). The proposed antenna exhibits high gain, with values of 6.68, 7.56, and 8.54 dBi at 2.45, 3.5, and 5.8 GHz, respectively. Its compact size, high performance, and significantly lower SAR values make this design an excellent candidate for wearable healthcare, fitness monitoring, and different WBAN/MBAN applications.

Titre: Intelligent Agricultural Irrigation System Design And Implementation Auteur(s): HAMZA, Azzeddine; KOUACHE, Anfal; MOKHTARA, Safa Résumé: Water scarcity and inefficient irrigation practices remain critical challenges in agriculture, particularly in arid and semi-arid regions. This thesis presents the development of a smart irrigation system that leverages the Internet of Things (loT) and fuzzy logic control to optimize water usage and promote sustainable agricultural practices. The proposed system integrates low-cost sensors to monitor environmental parameters such as soil moisture, temperature, and humidity in real time. An Arduino-based microcontroller processes these inputs using a fuzzy logic inference system to make intelligent irrigation decisions. The item sues A seme cary me wais designes , sinabling uranian in ing under uncertain conditions and dynamically adjust irrigation duration and frequency. Field-level testing demonstrated that the system can maintain optimal soil moisture levels while reducing water consumption by up to 30% compared to manual irrigation methods. The results confirm that the integration of loT with fuzzy logic provides an effective, scalable, and accessible solution for precision irrigation. This work contributes to the advancement of intelligent farming technologies and offers a practical model for future deployment in water- sensitive agricultural environments.
