Item Design and implementation of a student communication platform "IGEE space"(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2023) Rahali, fares; Zitouni, Abdelkader (Supervisor)In recent years, social media platforms have become one of the main communication tools between students and faculty. However, because of its side effects including distractions, privacy, data security, and fake news, a new Student Communication Platform has been designed and implemented to provide students, teachers, and administrations with a reliable, and safe environment to communicate, collaborate, and interact with each other. The project's aim is to create a dedicated space that is free from the distractions of social media platforms and keep the students’ information private. This platform offers features such as creating posts, sharing files, group chat, notifications, project proposals, and personalized profiles making it an all-in-one solution for student communication. The Student Communication Platform is a web-based application, that makes it accessible through many different devices and browsers. The process of building this platform went through two phases, the system design phase is demonstrated through the use of UML and entity- relationship diagrams, while the implementation showcases the utilization of Next.js, Tailwind CSS, and Supabase as programming tools. The Student Communication Platform project fulfilled all requirements, delivering a dependable, focused, and protected space for student communication.Item Design and implementation of a web-based geographical information system(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2023) Meddane, Sara; Zitouni, Abdelkader (Supervisor)This study deals with the design and implementation of a web-based geographical information system for the management of hydrocarbon exploration sites(latter on refereed to as ”acreages”), at the level of the Exploration Division, SONATRACH, that should help the involved stakeholders to efficientl ymanage and exchange information.

However, in modern WDM (Wave Division Multiplexer) systems where several optical carriers of different wavelengths (or frequencies) may share a single fiber, the Erbium Doped Fiber based amplifier (DFA), one of the most commonly used type of amplifiers, shows non-uniform gain characteristics with respect to the carrier frequency. In addition, The default parameter values used to carry out system analysis using simulation tools do not necessarily give accurate results. The objective of this work is therefore to conduct a study and an analysis of the EDFA to show first its behavior when used in WDM systems and estimate the best frequency range (operating band) of use and, second to estimate better (optimal) parameters values that should be used with a simulator (Optisystem) to obtain more reliable analysis of WDM transmission systems rather than default ones provided by the software.Item Performance analysis of dispersion compensation using FBG and DCF in WDM systems(2021) Benamrouche, Lina; Zitouni, Abdelkader (Supervisor)This project is about studying several factors and dispersion compensators that affect the performance parameters in WDM optical fiber transmission systems. At frequency of 193.1THz with spacing frequency of 100Ghz. In the first part of the simulation, 4-Channel WDM system is designed and simulated. Only the results of channel 1 which got discussed as Q factors and eye diagrams dependent on change in distance, transmission rates and input power values, then on FBG and DCF added as dispersion compensators in different configurations. In the next part, 8-Channel WDM system is designed and simulated for 60Km transmission distance at 5GBit/s transmission rate and input power of 10dBm. The results of channels 1, 5 and 8 are discussed for different DCF and FBG techniques. Finally, 2-Channel WDM system is designed and simulated for 120Km, at 6GBit/s for input power of 10dBm. The results of channel 1 and 2 are discussed for multistage FBG and DCF techniques.

This web application makes it possible to facilitate the work of the members of the administration and teachers by automating the management of students in promotions and groups, assigning teachers to courses, gradessubmission, semestrial and annual results, and the users' roles. To improve the students' evaluation process, this project goal is to analyze the current processes and situations in students' evaluation and determine the possible areas of improvement. This work has been carried out using the modelling language, Unified Modelling Language (UML), for designing the application. As for the implementation, we have chosen to develop the application with NodeJS, MongoDB as the Database Management System (DBMS), and ReactJs for creating user interfaces.Item Student information management system(2022) Derouche, Abdelmoumene Dhia; Hddouche, Yacine El Hakim; Zitouni, Abdelkader (Supervisor)Digital transformation in Algeria is now a must to keep up with the fast-changing world; and universities are expected to lead this transformation. However, many procedures in the Algerian universities are done in the traditional way, including the registration of students, display of grades, and sharing of important news. This leads to less efficiency for the university and a degrading in students' performance and mental health. The aim of this work is to create a system in order to make the nteraction between the university and the student more efficient and convenient for both. The project includes the creation of a cross platform mobile application with few features; It allows the administration to share important news easily without resorting to other platforms, gives the students the ability to receive their grades privately, provide a tool to manage their tasks, and allow them to share posts to inform their colleagues of something or ask for help. The application is supposed to be managed by the university, and the used students' data is acquired when the administration registers the new student.This is possible because we have created a server where we implemented API endpoints that receive requests from a client to manipulate data that is stored in a cloud database. The server is hosted on the cloud to make it more accessible,and images are stored in a cloud object storing service. This implementation makes the students'nformation easier to control, which is convenient. An early version of the user-friendly application was released before making all the features and received positive results from the students whom we showed it to. Finally, after addingthe main features we described the app is ready to be tested with a bigger database in our institute.Item Powera, AC line properties acquisition with mesh lora communication and flexible transient state protection(2021) Chikh, Wafa; Saidi, Omar; Zitouni, Abdelkader (Supervisor)From big industries and factories to houses and residences, the entire modern civiliza- tion relies on electricity to operate and prosper. With several effective methods of generating electrical energy, measuring and tracing that energy is more than a simple counter concept, with existing human interaction dependent meters, errors, data tampering and mishandling are as common as faulty uncalibrated meters. These exact problems, snowball by time into either taxes on the consumer's end, in- flating the bills to triple and even quadruple their usual one, or considerable profit loss to the supplying company. this resulted in the necessity of providing a pre-calibrated, accurate, and human interaction independent device. Adding to the whole system measurement problems, the communication of data and the infrastructure needed is a crucial point to be altered as wires, wireless tours, and satellites all inflate the cost of electrical energy being distributed, that is why LoRa technologies became a go-to response to all wireless long-range uses and cases where mesh custom protocol was developed since electricity can be imperceptible in many cases.All the problems raised above can be solved and implemented into an advanced me- tering infrastructure, with the idea of power measurement and LoRa communication in mind, PoweRa was implemented using the embedded Analog Front End Integrated Circuit, thus providing highly accurate and precise measurements for all AC line prop- erties, LoRa mesh-like protocol which increases in range with each peer being installed as data will bounce from node to node in a short path algorithm covering a perimeter of at least 15KM. The PoweRa system is complemented by a safe and maintenance-free package, heavy- duty solid state relays were used to trigger the line protection responding to a transient state overvoltage/overcurrent triggering prediction algorithm.Keywords: Energy metering, Mesh Long Range communication, energy metering, protection.Item Passive networks simulation Based on Graph theory(2020) Hamadi, Amel; Zitouni, Abdelkader (Supervisor)The aim of this project is to build a passive linear networks simulator for both time and frequency analysis including mutual effects that may occur between the mutual branches of the network. After a quick survey on the different topological network analysis techniques, we based our work on the Modified Nodal Analysis (MNA) technique which has been selected to implement our algorithm, The final code is written in MATLAB programming language and presented as Graphical User Interface (GUI). The results obtained after simulation are displayed as plots or can be saved in a disk file for further processing.Item Study and simulation of the link adaptation technology in the LTE standard(2016) Meziane, Mokrane; Allilat, Fetta; Zitouni, Abdelkader (Supervisor)The Long Term Evolution first introduced by the link adaptation system as a massive step forward in the control of the network resources. It is mainly based on measuring instantaneous Signal to Interference and Noise Ratio (SINR) which is used to investigated the influence of several parameters on the link adaptation error characteristics. Adaptive Modulation and Coding (AMC) is used to increase the network capacity or downlink data rates. Spatial multiplexing techniques for MIMO antenna configurations are also considered. This report has outlined the various scheduling techniques used in the link adaptation process to increase the throughput of the network. Three major channel state report measurements are used to perform the adaptations which are: CQI (channel quality indicator), PMI (Precoding Matrix Indicator), and RI (Rank Indicator) measurements. An analysis and a comparison of these scheduling algorithms were done through simulations executed on MATLAB software. The impact of the scheduling schemes was examined on the throughput (Average Data Rate) and the Bit Error Rate (BER), and it was compared to the case where no adaptation is done. The fairness of the results given by each scheduling scheme was investigated. The link adaptation improved the transmission robustness through minimizing the error and increased the spectral efficiency to produce a satisfactory average data.Item Digital Filters for reducing the effects of dispersion in optical communication(2016) Grainat, Youcef; Mebarki, Yaser; Zitouni, Abdelkader (Supervisor)The aim of this project is to use digital filters to reduce the effects of dispersion in modern WDM optical communication systems at two transmission speeds, 2.5 and 5 Gbps. For this purpose two types of filters [Gaussian Filter (GF) and Cosine Roll Off Filter (CROF)] have been tested by simulation using OptiSystem and Matlab in single mode fiber links at the operating wavelength of 1550 nm. From the obtained results a comparative study with respect to the conventional Dispersion Compensating Fibers (DCF) has been carried out.
