Item Design EMI filter using Multi-Objective Optimization for Mitigation of Conducted Noise at Photovoltaic System(University of Eloued جامعة الوادي, 2019-02-24) F. BEGGAT,; F. BOUCHAFAAAbstract—Electromagnetic interference (EMI) generated in a photovoltaic (PV) system issue has become one of the extremely important problems to be solved. It is well known that the inverter used in PV system is major sources of conducted disturbances which are the common mode and differential mode. Often, the solution used to reduce conducted emissions consists to use the EMI filters. In some cases, EMI filter assemblies require up to 40% of the total installation space of an inverter. These mechanisms lead to increasingly tougher demands on filter assemblies in terms of insertion loss and volume. To solve this problem, an automatic design optimization tool based on a co-simulation MATALB and LT- SPICE oriented at obtaining high performing EMI filters with the minimum volume and filter attenuation. A Database information of commercially available passive components (e.g. magnetic cores, capacitors), this last one allowed feed the program of design under MATLAB. Finally, the final phase allowed validating the filter performance with a temporal solver and frequency under LT-SPICE. Simulation and experimental results give a firm support to the proposed method.Item BIOCARBURANTS ET CHANGEMENT CLIMATIQUE BIOFUELS AND CLIMATE CHANGE(University of Eloued جامعة الوادي, 2019-02-24) KRIM HassanDepuis le début des années 2000. Les politiques publiques en faveur des biocarburants, se sont considérablement renforcées et élargies à un grand nombre de pays, l’un des objectifs principaux est La lutte contre le changement climatique grâce à la baisse des émissions de gaz à effet de serre(GES). Les biocarburants participent à cet objectif, puisqu’ils constituent une des alternatives possibles aux carburants fossiles (ADEME 2010). Cependant, ils sont à la croisée de plusieurs enjeux significatifs : économiques, sociaux, environnementaux, et climatiques. Dans ce contexte, il est apparu nécessaire d’évoquer les impacts que peut présenter le développement incontrôlé des biocarburants qui sont accusés de ne pas présenter les bilans avantageux qu’on leur avait prêtés dans un premier temps en termes de réduction des émissions de gaz à effet de serre.Item Impact of climatic conditions on photovoltaic modules performance(University of Eloued جامعة الوادي, 2019-02-24) Mustapha DIDA; Slimane BOUGHALI; Djamel BECHKI1; Hamza BOUGUETTAIASignificant advances have been made in PV systems within the last few decades. However, designers still face challenges related to the effects of climate conditions on PV systems performance. Climatic conditions such as temperature, humidity, wind velocity, solar irradiation and dust accumulation can effect significantly on the performance of PV modules. This experimental work aims to determine the effect of two parameters (PV module temperature and dust accumulation) on output power of solar PV panels in arid area. The experimental results showed the effect of dust accumulation in drooping of photovoltaic energy production, with decreasing by 5.35%, 0.38% and 5.94% in short circuit current, open circuit voltage and maximum power output respectively compared to cleaned PV panel. In the other hand results showed that the open circuit voltage and maximum power of non-cooled PV module are lower than cooled module by 5.64% and 6.35% respectively.Item OPTICAL PROPERTIES OF CH3NH3PbI3 BY SPRAY PYROLYSIS WITH MOVING NOZZLE(University of Eloued جامعة الوادي, 2019-02-24) Kemerchou Imad,; Rogti Fatiha; Benhaoua Boubaker; Hima Abdelkader,; Lakhdar NacereddineOrganic-inorganic perovskite based solar cells are a promising material in recent research.

Boukelia; A. Ghellab; A. Laouafi; A. BourouiAbstract— Unlike conventional thermal power plants which are generally erected in the coastal regions near water bodies, seas and oceans, where water resource availability is not a critical factor, concentrating solar power (CSP) plants are usually installed in high sunny zones which generally characterized by semi-arid and arid climates, where water resources are hard to find and/or to employ. On the other side, the hourly simulations of water consumption in CSP plants are very complex and require many calculations, data analysis and time consuming. Therefore, the aim of this paper is to develop a simple equation to estimate the hourly water consumption of a solar tower plant based on its generated power, and the existing power plant Gemasolar has been chosen to establish the methodology. The obtained results of the statistical analysis show that the cubic model based on the generated power, can be used as a simple and general model to predict hourly water consumption in a large scale solar tower power plant.Item التنميه المستدامة وريادة الألعمال: المساهماث السابقة والإلتجاهاث المستقبلية(University of Eloued جامعة الوادي, 2019-02-24) مفيد عبدالالوي; فرحات كلثوم; هيبة خسازنةيف ظل التغَتات ادلتسارعة اليت تشهدىا بيئة األعمال والضغوط ادلرافقة للمنافسة العادلية، تويل العديد من ادلنظمات االىتمام لتبٍت ادلفاىيم اإلدارية احلديثة، وتعترب ريادة األعمال من ادلواضيع االقتصادية واإلدارية احملدثة اليت أولتها األدبيات ،ً إن ىذه التغَتات اذلائلة أصبحت مصدرا خصبا للرياديُت لإلتيان بأفكار إبداعية وابتكارات جديدة، ادلعاصرة اىتماما وثيقا وتعترب الريادة أداة ووسيلة ىامة خللق الثروة وادلعرفة، من أجل حتقيق أىدافها االقتصادية واالجتماعية، ومن مث حتقيق التنمية ادلستدامة، وقد ركزت األىداف اجلديدة ذلذه األخَتة على رسم غايات حول كيفية النهوض بالصناعة واالبتكار واإلبداع وريادة ا وعلى أيدي مجيع سكان األرض ً األعمال، وأعطت نقاطً ، من ا زلددة للخروج من أزمة استهالك التكنولوجيا إىل ابتكارىا زللي خالل تعزيز التصنيع الشامل للجميع وادلستدام، وحتقيق زيادة كبَتة يف حصة الصناعة يف العمالة ويف الناتج احمللي اإلمجايل، وزيادة فرص حصول ادلشاريع الصناعية الصغَتة على اخلدمات ادلالية، مبا يف ذلك خدمات االئتمان قليلة التكلفة، وتضمنت تلك التحتية، وحتديث الصناعات؛ لتحقيق استدامتها، مع حث دول العامل على زيادةكفاءة استخدام ادلوارد، ى ٌُت األىداف، حتسُت الب ا، مؤكدة على أمهية تعزيز البحث العلمي، وحتسُت القدرات ً وزيادة اعتماد التكنولوجيا والعمليات الصناعية النظيفة والسليمة بيئي التكنولوجية يف القطاعات الصناعية يف مجيع البلدان.Item The Ohmic and activation over-potential in Anode- Supported Solid Oxide Fuel Cells(University of Eloued جامعة الوادي, 2019-02-24) Horr Sabrina; Hocine MohceneA multi-dimensional model has been established to investigate the performance of anode-supported SOFC fuel cell with two different configuration, :i) the Anode Supported Planar Solid Oxide Fuel Cell (ASP_SOFC) with channel gas surface 1mm2 and ii) ASP_SOFC with channel gas surface 0.25mm2. The numerical simulation was realized with a SOFC fuel cell model based on the ANSYS FLUENT computational fluid dynamics (CFD) software. The simulation results were illustrated polarization curves including J–V,J–P, Ohmic and activation over-potential curves. It was found that the increase in channel surface has more significant influences on the cell performance. The model is validated using one of the available numerical results from previous researches the comparison between the numerical model and the reported results shows very good agreement.Item The Impact of Envelope Building Materials On The Thermal Comfort .Case of hot and dry climate(University of Eloued جامعة الوادي, 2019-02-24) Khaled Mansouri; Leila SritiEnvelope Building materials play an important role in the architecture by providing the protection requirements, comfort, and technical performance while promoting an architectural language and an image. The impact of the building materials varies according to their physical, chemical, mechanical and thermal properties; Also, their interaction with the environmental factors: heat, humidity ... etc. Therefore choosing the right building materials is a key factor in achieving a certain level of comfort inside the building witch effect directly the energy use and consumption. In this study, we investigate the impact and the thermal behavior of different envelope materials, the most used materials; traditional and modern under the climatic conditions of Biskra a hot and arid climate. Also, we analyzed the results of a different simulation using “ecotect5.0” to performed thermal analysis and we used “opaque3.0” and “u-wert” to figure some envelope materials proprieties in order to choose the best material that ensures thermal comfort inside the building. The results show that choosing local massive materials and thermal insulation can achieve that to a certain degree.Item Evaluation of the anti-Alzheimer's disease activity of N-ferrocenylmethyl-2-nitroaniline using bioinformatics tools(University of Eloued جامعة الوادي, 2019-02-24) ZEGHEB Nadjiba; BOUBEKRI Cherifa; LANEZ TouhamiInhibition of acetylcholinesterase is currently regarded as the leading strategy against Alzheimer's disease. The principal objective of this project was to investigate the acetylcholinesterase inhibitory activity of N-ferrocenylmethyl-2- nitroaniline (2FMNA) using the bioinformatics tools to predict the relationship between them. In this research, we based on docking study of the interaction between N-ferrocenylmethyl-2-nitroaniline and the AChE by using the open source software AutoDock tools. The X- ray crystal structure of the enzyme AChE (PDB ID :5HF5) were obtained from Protein Data Bank (http://www.rcsb.org./pdb). The N-ferrocenylmethyl-2-nitroaniline structure chosen for docking was optimized with the Gaussian 09 software by the DFT method and the set of B3LYP / 6-311G ++ (d, p) bases. The interaction parameters obtained from molecular docking show that the interaction between 2FMNA and the enzyme is of the electrostatic type.Item Mechanical response of functionally graded beams with porosities(University of Eloued جامعة الوادي, 2019-02-24) Abdelkader SAFA; Lazreg HADJI; Mohamed BOURAADAThis work presents a free vibration analysis of functionally graded metal–ceramic (FG) beams with considering porosities that may possibly occur inside the functionally graded materials (FGMs) during their fabrication. A new displacement field containing integrals is proposed which involves only three variables. Based on the suggested theory, the equations of motion are derived from Hamilton’s principle. This theory involves only three unknown functions and accounts for parabolic distribution of transverse shear stress. In addition, the transverse shear stresses are vanished at the top and bottom surfaces of the beam. The Navier solution technique is adopted to derive analytical solutions for simply supported beams. The accuracy and effectiveness of proposed model are verified by comparison with previous research. A detailed numerical study is carried out to examine the influence of the porosity on the free vibration responses of functionally graded beams.Item Simulation Numérique de la Dépollution d’un Milieu Poreux Contaminé par un Hydrocarbure(University of Eloued جامعة الوادي, 2019-02-24) ZOUAOUI Salah; DJEBOURI Hassane; MOHAMMEDI Kamal; HAMZAOUI MalekRésumé—La présence fréquente de contaminants im- miscibles (hydrocarbures, solvants chlorés) dans les formations souterraines peut constituer un grand dan- ger pour la santé humaine. La dépollution de ces formations s’avère, alors, nécessaire afin de préserver les écosystèmes et les futures générations. Il existe plusieurs techniques permettant d’extraire de polluants à partir du sol. La technique utilisée va dépendre essentiellement du type de polluant et de la nature du milieu. La simulation numérique, basée sur des modèles mathématiques, est devenue aujourd’hui un outil incontournable qui peut aider à la compréhension de beaucoup de phénomènes naturels notamment lors du transport de polluants dans le milieu souterrain. L’objectif de ce travail est de simuler en 3D la dépollu- tion d’un milieu poreux, assimilé à un parallélépipède, initialement saturé avec un hydrocarbure. De l’eau sous pression est injectée pour déplacer le polluant vers un point de soutirage. Le modèle est résolu par le code de calcul UTCHEM-9.0 qui est un simulateur multi- phasique basé sur la méthode des différences finies. Les résultats obtenus sont présentés sous forme de champs de saturation.Item Optimisation des paramètres de la fermentation des dattes pour les transformés en bioéthanol(University of Eloued جامعة الوادي, 2019-02-24) Zeghoud Soumeia; Med.

The most economical way to obtain drinking water is solar distillation using free, renewable and non-polluting energy. Improvement of the single-slope solar distiller is a problem addressed by several researchers around the world. This study also aims at this point by the variation of the thickness of the glass (the condenser). Experiments show that the production is better improved when the thickness of the glazing is low e = 3 mm with a total production of 2313.2 ml /m2.d; when e = 5 mm the production is 1876 ml / m2.d and at the end when e = 6 mm the production is 1236 ml / m2.d. From these results can be said that any increase in thickness will be followed by a decrease in the productivity of distilled water.Item DFVELOPMENT OF NEW LOW COST MATERIALS FOR ENVIRENEMENT TRAITEMENT(University of Eloued جامعة الوادي, 2019-02-24) Derafa Garmia; H.ZAGHOUANE-BOUDIAFWater is a basic unit for the continuation of the life.
