    A New Rotor Broken Bar Fault Diagnosis by Using CNN Based Current Signal of An Induction Motor
    (University of Eloued, 2023-12-11) ADAIKA Hamza; TIR Zoheir; SAHRAOUI Mohamed
    Abstract— In industrial contexts, the efficient operation of induction motors is paramount, necessitating robust condition monitoring and fault diagnosis techniques to mitigate costly disruptions. In this study, we introduce an innovative approach for intelligent fault detection of broken rotor bars in induction motors, harnessing the "Signal2Image" method and convolutional neural networks (CNN). Leveraging a comprehensive current signal dataset from Aline Elly Treml Western Parana State University, encompassing various levels of broken rotor bar (BRB) faults and diverse loading conditions, our method automatically extracts essential features from input data. The "Signal2Image" process transforms time-domain current signals into 2D grayscale pixel images, facilitating CNN-based image classification to identify fault-related patterns. Through meticulous CNN parameter tuning, we achieve an impressive fault classification accuracy of 88% across all fault cases while optimizing computational efficiency. A significant contribution of this work is the substantial reduction in computational time for fault classification, surpassing existing approaches. This research enhances fault detection accuracy and streamlines the process, contributing to the field of predictive maintenance for induction motors.

    Apport de l’intelligence artificielle combinée avec les systèmes d'information géographique pour l’identification des Ghouts menacés de disparition
    (University of Eloued, 2023-12-11)
    Le développement économique remarquable qui a connu la vallée du Souf, au Sud-est de l'Algérie, suite à l’activité agricole intense, avec une croissance démographique significative accompagnée par une extension du tissu urbain, touts ces facteurs ont entraîné une augmentation de la demande d'eau souterraine, qui est la principale source à des fins domestiques, agricoles et industrielles, dans une région aride. La mauvaise gestion de cette importante ressource d’eau a entraîné des perturbations dans l'écosystème local, y compris les Ghouts, qui caractérisent la région du Souf, et en raison de son importance historique, économique et environnementale elle a été classée par l'Organisation des Nations Unies pour l'Alimentation et l'Agriculture (FAO) comme patrimoine agricole mondial. Ce système agricole durable et non irrigué, totalement dépendant de la nappe phréatique, est confronté à de nombreux problèmes qui le menace de disparition (submersion, rabattement de la nappe, conditions climatiques extrêmes, etc.). Cette étude vise à identifier les Ghouts menacés par la dégradation, dans la vallée du Souf, en utilisant l’intelligence artificielle (apprentissage profond par réseaux de neurones) et les images satellitaires, sur plusieurs séries temporelles. Ainsi, dans l’identification des futurs Ghouts menacés de disparition dans un futur proche. Les résultats montrent que les Ghouts de la région Sud-est de la vallée risquent de disparaitre d’ici dix ans, ce qui fait un pourcentage de 23% de la totalité des Ghouts de la région d’étude seront perdus.

    Artificial Intelligence for mapping the spatial and temporal variation meteorological drought in the Aures, Algeria
    (University of Eloued, 2023-12-11) Okba MoussaouiI; Khemissi Yahiaoui; Ali Hachemi
    Insects are a readily available source of chitosan due to their high reproductive rates, ease of breeding, and resistance to changes in their ecosystem. This study aims to extract chitosan from some of the widespread insects: Pimelia fernandezlopezi (CS-PF), Blaps lethifera (CS-BL), and Musca domestica (CS-MD). The study was also extended to using the obtained chitosans in removing methylene blue dye (MB) from wastewater. The source of the chitosan, the initial concentration of MB dye, and reaction time were chosen as working parameters. The experiments were designed using Central Composite Design (CCD) based on the dye removal efficiency as the response variable. The experimental work and statistical calculation of the CCD show that the dye removal efficiency ranges from 35.9% to 88.7% for CS-BL, from 18.8% to 47.1% for CS-PF, and from 10.3% to 29.0% for CSMD at an initial MB concentration of 12.79 mg/L. The highest methylene blue dye removal efficiency is 88.7% for CS-BL at a reaction time of 120 min. This indicates that the extraction of chitosan from insects (Blaps lethifera) and their application in dye removal is a promising, environmentally friendly, economical, biodegradable, and cost-effective process. Furthermore, the CCD is a statistical experimental design technique that can be used to optimize process variables for removing other organic pollutants using chitosan

    Comparative Study between Direct Torque and Direct Power
    (University of Eloued, 2023-12-11) HammoudiiBen ail; Hicham Serhoud
    This paper presents a comparative analysis of two control strategies applied in wind energy systems: direct torque control (DTC) and direct power control (DPC) of a Doubly-Fed Induction Generator. As the demand for renewable energy sources continues to soar, optimizing the efficiency of wind turbines is paramount. The study meticulously examines the advantages and performance characteristics of both control methods to shed light on their strengths and limitations. In the case of DTC applied to a DFIG, achieving minimal torque response time and eliminating the need for PI controllers prove advantageous when the DPC control strategy eliminates the necessity for rotor current control loops and PI controllers to control the stator active and reactive powers. Finally, the performance of the system is tested and compared by simulation in terms of robustness and pursuit tests based on Matlab/Simulink software.

    L’utilisation du charbon actif est restée pendant longtemps et jusqu’à ce jour l’un des adsorbants les plus efficaces, grâce à sa forte capacité d’adsorption due essentiellement à sa grande surface spécifique, mais le coût du traitement pour l’obtenir est élevé, ce qui rend ce dernier non concurrentiel du point de vue économique. L’attention a été focalisée par la suite, sur l’utilisation de nouveaux adsorbants à base de matériaux naturels abondants, tels que (les grignons d’olive et les noyaux de dattes). La présente étude a donc pour objectif d’étudier l’adsorption du plomb sur un charbon actif préparé par les noyaux de dattes (Déglette Nour) de la région de Biskra du sud algérien. Dans les conditions opératoires optimales on a trouvé un taux de capacité d’adsorption maximale de plomb de 36.04%. Les données expérimentales ont été bien décrites par l’isotherme de Langmuir qui a donné une capacité d'adsorption de 16,2197 mg/g par apport aux modèles de Freundlich

    (University of Eloued, 2023-12-11) Tabet Amina; Souhaila Meneceur; Salah Eddine Laouini; Salmi Chaima; Hamdi Ali Mohammed; Iman Kir
    The current investigation is centered on the sustainable synthesis, physical characterization, and performance evaluation of various metal oxide nanoparticles (NPs) produced utilizing an extract derived from Common Rue. Following the synthesis of metal oxide NPs, including ZnO/CuO/Cu2MgO3, a comprehensive characterization was carried out employing various techniques such as FTIR, UV, XRD, and SEM to scrutinize their chemical and physical attributes. Photocatalytic activity was evaluated by assessing their effectiveness in degrading bromocresol green, an anionic dye. The characterization results substantiated the successful fabrication of ZnO/CuO/Cu2MgO3 nanoparticles. X-ray diffraction analysis verified the presence of hexagonal ZnO and monoclinic CuO nanoparticles within the nanocomposite, along with cubic Cu2MgO3. Scanning electron microscopy illustrated well-defined, spherical nanocomposite particles with an average size of approximately 70 nm. Fourier transform infrared spectroscopy demonstrated the coexistence of both organic and inorganic components within the nanocomposite. These nanoparticles exhibited respective band gap energies of 1.5 eV. The study on photocatalytic activity revealed a substantial removal of the organic dye by the synthesized nanoparticles, achieving a degradation coefficient of 99.66% at 75 minutes. These findings underscore the efficacy of ZnO, MgO, and CuO nanoparticles, suggesting their potential as a cost-effective and environmentally safe alternative for water treatmen

    (University of Eloued, 2023-12-11) Mohammed Faouzi LACHEHEB; Salah Eddine KHETTA; Salim KHECHANA; Abdennour LAMOUDI
    Le développement social et économique important qu'à connaît la région d’Oued Souf est entravé par l'insuffisance des ressources en eau et ce déficit en eau nécessite également une gestion rationnelle de cette ressource. L'estimation de l'évapotranspiration est une étape essentielle dans la modélisation de la production agricole et la planification de l'irrigation. Dans notre étude, une comparaison de cinq méthodes d'estimation de l'évapotranspiration a été faite: Blaney-Criddle, Thornthwaite, Turc, Penman et Monteith - approuvée par FAO et la formule approuvée par l'agence nationale des ressources hydriques (ANRH). Dans cette étude, nous avons adopté des outils statistiques (programme SPSS) tels que l'erreur relative et l'équation linéaire pour déterminer le coefficient de corrélation, le test T, la moyenne arithmétique et l'écart type, afin d'élaborer le bilan hydrique qui montre un déficit tout au long de l'année. Nous avons arrivé à montrer que la formule de Penman et Monteith approuvée par FAO est la méthode la plus appropriée pour calculer l'ETP, non seulement pour la zone d'étude mais dans toute zone ayant les même conditions et caractéristiques climatiques

    (University of Eloued, 2023-12-11) Iman Kir; Laouini Salah Eddine; Meneceur Souhaila
    Synthesis using plant extracts is a simple, environmentally friendly and inexpensive method to prepare nanoparticles effective in photocatalytic applications. In this study, aqueous extract of lemon peel was used to synthesize copper oxide nanoparticles (NPs) and then the obtained copper oxide nanoparticles were modified with polyethylene glycol (PEG). The optical properties and photocatalytic activities of the synthesized nanoparticles were studied. CuO NPs and CuO/PEG NPs showed a ball-like morphology with average sizes of 34 nm and 45 nm and optical band gap energies of 1.2 eV and 1.5 eV, respectively. In photocatalytic activity tests, CuO/PEG NPs showed higher activity compared to CuO NPs alone. They achieved degradation rates of 99.7% for 4-bromophenol dye (BP) and 99.5% for toluidine blue dye (TP) after 90 min, while CuO NPs achieved slightly lower rates. CuO NPs and CuO/PEG NPs showed significant photodegradation activity against amoxicillin (an antibiotic), with degradation rates of 91% and 98%, respectively, after 120 min. The reaction kinetics of CuO/PEG NPs and CuO NPs followed a pseudo-order model, with CuO/PEG NPs showing a higher rate constant than CuO NPs. Overall, modification of CuO NPs with PEG showed excellent photocatalytic properties for environmental remediation, indicating their potential use in wastewater treatment and therapeutic applications

    Heat-treated oil well sand and its exploitation in construction
    (University of Eloued, 2023-12-11) Mani Mohammed; Tarek Djedid; Logbi Abdelaziz
    When extracting petroleum during the drilling and exploration process, large quantities of sand are left behind from petroleum wells. This sand is often mixed with drilling fluids containing environmentally harmful substances. Many international organizations have recognized the danger of these sands, prompting oil-producing countries to take measures and enact strict laws to deal with this issue. Several global research studies propose various solutions, including the possibility of using heat to extract harmful chemicals and then disposing of the treated sands as non-contaminated. It is known that treating these sands with heat, reaching temperatures up to 500 degrees Celsius, can alter many of their chemical and physical properties. The question arises: can we use these heat-treated sands in construction in general, and specifically as a binding material? When using heat-treated petroleum well sands as a 100% binder, we achieve a bending resistance of 1.50 MPa and a compressive strength of approximately 0.8 MPa after 28 days. These properties improve as we add a considerable percentage of CaO, considered as clinker. When using a mixture of 50% cement and 50% heat-treated petroleum sands, the bending resistance at 28 days improves to 2.23 MPa, and the compressive strength increases to 4.8 MPa. Further improvement is observed when increasing the cement ratio to 70%, resulting in a bending resistance of 4.05 MPa and a compressive strength of 6.8 MPa after 28 days. 106In conclusion, the heat-treated petroleum sands show promising potential for use in construction, especially when combined with cement, offering improved mechanical properties.

    (University of Eloued, 2023-12-11) DAHMANE Laoud; ZAIR Nadjet; SALIM Khechana
    The Djelfa Region, a prominent semi-arid area in Algeria, experiences leachate emergence due to the physico-chemical and biological dissolution of pollutants in percolating waters. The dissolution and chemical precipitation mechanisms during infiltration are closely linked to various aquifer system compartments, including soil, unsaturated zones, and saturated aquifers. This research aims to assess environmental risks in the Djelfa Region, particularly from uncontrolled or compacted controlled landfill sites, by investigating water and soil contamination resulting from public dumping. The primary objective is to investigate the impact of leachate from uncontrolled and controlled public landfills on water and soil resources. Physicochemical analyses, including pH, conductivity, salinity, temperature, turbidity, O2 dissolved, Cl-, NO3-, HCO3, SO4-2 Mg+2, and Ca+2, along with the determination of certain pollutants (BOD5, COD, NO3-, NH4+, NH2) and organic matter, will be conducted on a network of wells and a leachate point. Additionally, several campaigns of piezometric measurements will be carried out as part of this study

    (University of Eloued, 2023-12-11) BOUSLAH Soraya; DJEDAOUNE Amel
    Surface water from the Hammam Debagh dam is one of the main sources of drinking water for the population of the town of Guelma. The aim of this study is to apply artificial neural networks to predict the coagulant dose for the potabilisation process at the Hammam Debaghe plant, using the various quality parameters of the raw water received from the Bouhamdane dam reservoir. The application of this model for coagulant dose prediction is of particular interest given its simplicity and ease of use for estimating the daily coagulant dose of the treatment process. These results can be a very good indicator for operators and can be used to help manage and operate the various compartments of the treatment process. Overall, the results show that RNA models are promising alternatives for coagulant dose estimation. However, further improvements to RNA structures need to be investigated. However, further improvements to the RNA structures need to be investigated. The input data for the MCP model are pH, temperature, turbidity and conductivity in the raw water at the plant inlet. The model built to predict the coagulant dose of the treatment process in the Hammam Debaghe treatment plant consists of 4 neurons in the input layer, 9 neurons in the hidden layer, and 1 neuron in the output layer. The results of the model show that the regression coefficient R = 0.8066, indicates that the PMC model is able to respond well to the training data and is able to reconcile them. The PMC model is therefore able to solve the specific problem of inputoutput data mapping. Using this model will therefore enable operators to: Reduce the costs and time required to carry out experimental Jar-tests; as well as predict an appropriate dosage for the quantities of coagulant to ensure the production of drinking water in compliance with Algerian standards.
