We study the free vibration of an Euler-Bernoulli beam without internal damping. By applying suitable control at the free boundary, we can exponentially dampen these vibrations. The exponential stability was proven using the Lyapunov method, and the results were confirmed through numerical simulation.]]>
Une contribution à l’étude numérique d’un écoulement turbulent d’air en présence des chicanes transversales a été menue. Deux différentes formes de chicanes rectangulaire plane et trapézoïdale, disposées en chevauchement dans une conduite de section rectangulaire est présentée dans cet article. Les équations gouvernantes, basées sur le modèle k - à bas nombre de Reynolds employé pour modéliser la turbulence, sont résolues par la méthode des volumes finis à l’aide de l’utilisation de l’algorithme SIMPLEC. Les profils de vitesse ont été obtenus pour toute la géométrie considérée et pour différentes sections choisis, à savoir, en amont, en aval et entre les deux chicanes, ainsi que les coefficients de frottement ont été obtenues pour différentes sections et pour différents nombres de Reynolds.]]>

A new type of non-polynomial fractional spline function for approximating solutions of Fredholm-integral equations has been presented. For this purpose, we used a new idea of fractional continuity conditions by using the Caputo fractional derivative and the Riemann Liouville fractional integration to generate fractional spline derivatives. Moreover, the convergence analysis is studied with proven theorems. The approach is also well-explained and supported by four computational numerical findings, which show that it is both accurate and simple to apply.]]>
La métallisation par sérigraphie est une des étapes les plus importantes dans la technologie d’élaboration des cellules solaires pour une production à grande échelle. Néanmoins, elle demeure dépendante de plusieurs paramètres variables. Pour le silicium multi cristallin, tout changement dans le procédé de réalisation des cellules solaires influence directement l’optimisation du profil de recuit de la métallisation par sérigraphie. Les plaquettes de silicium multi cristallin subissent toutes les étapes classiques de réalisation des cellules solaires comme le nettoyage chimique et la décontamination, une diffusion au phosphore et le dépôt du nitrure de silicium SiNx par PECVD (Plasma Enhanced Chemical Vapor Deposition). Il y a juste le dépôt du contact Argent Ag sur la face avant de la plaquette. Nous avons utilisé la pâte de sérigraphie Ag Ferro 3349. La grille métallique comporte six (06) motifs TLM (Transfer Length Method) pour les mesures de la résistance de contact. Le principal but de ce travail est le contrôle de la qualité du contact Ag/SiNx/n+-Si dans les cellules solaires au silicium multicristallin. Les mesures TLM révèlent une cartographie des valeurs de la résistance de contact pour chaque température. Le profil optimal de température de recuit est autour de 750 °C.]]>

Depuis une dizaine d’années, des efforts considérables ont été accomplis dans le domaine de nouveaux matériaux synthétisés à bas coût pour être intégrer dans les cellules solaires à base de couches absorbantes CIS: CuIn (S,Se)2, et GICS: Cu(In, Ga)(Se,S)2. On peut citer à titre d’exemple les couches tampons telles que: CdS, ZnS, CuxS et Ag2S. Ces matériaux ont attiré notre attention vu leurs facilité à être déposé par la technique SILAR, ‘Successive Ionic Layer Absorption Reaction’ sur du verre, une technique réalisée et automatisé pour la première fois à l’université des Sciences et de la technologie d’Oran. Les matériaux sont synthétisés au laboratoire de microscopie électronique et sciences des matériaux et caractérisés à l’Université de Bourgogne par la coopération de l’équipe. Les couches minces et nanostructures sont le sulfure de cuivre CuxS, le sulfure d’argent Ag2S, le sulfure de zinc ZnS, le disulfure de cuivre et d’aluminium CuAlS2 et le disulfure de cuivre et d’indium CuInS2 ont un gap optique fondamental de l’ordre de 1,5 - 2,5 eV pour CuxS, de 1,0 - 2,0 eV pour Ag2S, de 2,5 eV pour ZnS, de 3,5 eV pour CuAlS2 et de 1,5 eV pour CIS. Ces matériaux sont préparés par plusieurs techniques, telles que spray, Sol gel, SILAR et bain chimique. A notre connaissance, il y a deux chercheurs indiens qui oeuvrent dans ce domaine, Lokhande et Pathan [1, 4, 5] qui ont développé cette technique au sens propre du brevet de déposition. Ces matériaux peuvent être utilisés en optoélectronique comme couche tampon et couche absorbante pour cellule solaire, photoconducteur et photodiode, dans les applications de l’environnement comme capteur de gaz.]]>

In this paper, we consider a two-patch model coupled by migration terms, where each patch follows a Richards law. First, we prove the global stability of the model. Second, in the case when the migration rate tends to infinity, the total carrying capacity is given, which in general is different from the sum of the two carrying capacities and depends on the parameters of the growth rate and also on the migration terms. Using the theory of singular perturbations, we give an approximation of the solutions of the system in this case. Finally, we determine the conditions under which fragmentation and migration can lead to a total equilibrium population which might be greater or smaller than the sum of two carrying capacities and we give a complete classification for all possible cases. The total equilibrium population formula for a large migration rate plays an important role in this classification. We show that this choice of local dynamics has an influence on the effect of dispersal. Comparing the dynamics of the total equilibrium population as a function of the migration rate with that of the logistic model, we obtain the same behavior. In particular, we have only three situations that the total equilibrium population can occur: it is always greater than the sum of two carrying capacities, always smaller, and a third case, where the effect of dispersal is beneficial for lower values of the migration rate and detrimental for the higher values. We end by examining the two-patch model where one growth rate is much larger than the second one, we compare the total equilibrium population with the sum of the two carrying capacities.]]>
La qualité des générateurs photovoltaïques (GPV) installés jusqu’à présent pouvait être contrôlée uniquement par le biais de système de mesures onéreux et peu pratique. Deux points importants sont étudiés dans le cadre de ce travail. Dans la première partie, on s’intéresse au développement d’un dispositif automatique de caractérisation de module PV à base du PIC16F877 sous condition de fonctionnement réel. Nous présentons dans la deuxième partie, une évaluation pratique des performances électriques d’un module solaire en silicium amorphe a-Si:H hybride (couches minces inorganique/substrat organique) en temps réel, orienté vers le sud avec une inclinaison de 38°, meilleure orientation pour la ville d’Oran (Algérie).]]>

In this paper, a numerical method based on a finite difference scheme is proposed for solving the time-fractional diffusion equation (TFDE). The TFDE is obtained from the standard diffusion equation by replacing the first-order time derivative with Caputo fractional derivative. At first, we introduce a time discrete scheme. Then, we prove the proposed method is unconditionally stable and the approximate solution converges to the exact solution with order O(Δt2−α)O(Δt2−α), where ΔtΔt is the time step size and αα is the order of Caputo derivative. Finally, some examples are presented to verify the order of convergence and show the application of the present method.]]>
CIAS, ‘Cu (In Al) Se2’ thin films are prepared on the glass substrates using economical chemical bath deposition ‘CBD’ technique. The effect of pH adjustments before or after preheating the reaction mixture has been discussed in this paper in a detail. Due to pH adjustment the change in the preferential orientation on the structural properties and the band gap variation with respect to thickness on the optical properties, has also been discussed.]]>

In this paper, the blow-up of solutions for a Dirichlet-Neumann problem to initial nonlinear viscoelastic plate equation with a lower order perturbation of p(x,t)-Laplacian operator in the presence of time delay is obtained. Under suitable conditions on g and the variable exponent of the p(x,t)-Laplacian operator, we prove that any weak solution with nonpositive initial energy as well as positive initial energy blows up in a finite time.

La production décentralisée d’énergie électrique, bénéficie actuellement d’un essor très important. Plusieurs sources d’énergie renouvelables et gratuites, telles que le vent (éoliennes), le soleil (thermiques ou photovoltaïques), sont de plus en plus utilisées pour produire l’énergie électrique localement sur des sites isolés. A cause de l’inconstance du vent et de la lumière, la gestion de l’énergie constitue l’un des défis majeurs dans les systèmes électriques éoliens déconnectés du réseau, ainsi que dans les systèmes photovoltaïque-diesel. Nous présentons, dans cet article, la conception et la réalisation d’un module électronique de contrôle de charge et de gestion optimale de la production pour systèmes énergétiques hybrides tout en assurant la gestion efficace et intelligente de l’énergie électrique dans les systèmes énergétiques hybrides éolien-diesel et photovoltaïque-diesel.]]>

This paper investigates the modified projective synchronization (MPS) between two hyperchaotic memristor-based Chua circuits modeled by two nonlinear integer-order and fractional-order systems. First, a hyperchaotic memristor-based Chua circuit is suggested, and its dynamics are explored using different tools, including stability theory, phase portraits, Lyapunov exponents, and bifurcation diagrams. Another interesting property of this circuit was the coexistence of attractors and the appearance of mixed-mode oscillations. It has been shown that one can achieve MPS with integer-order and incommensurate fractional-order memristor-based Chua circuits. Finally, examples of numerical simulation are presented, showing that the theoretical results are in good agreement with the numerical ones.]]>
Increasing energy assumption and rising energy prices in the world forces to look for energy alternatives, one of the most promising is the photovoltaic energy. Solar cells made from organic materials are particularly attractive because they are relatively easy to produce, structurally flexible, and can be applied to large areas at low cost. Fill Factor is a more sensitive parameter compared to open-circuit voltage (Voc) and shortcircuits current density (Jsc). This FF depends also on the thickness of the active-polymer layer, on the morphology of the cathode-polymer interface and on temperature. In this article, we study the dependence of fill factor (FF) on different parameters in organic bulk heterojunction solar cells.]]>

Ce papier présente une méthode de simulation numérique pour la prédiction d’écoulement autour d’une éolienne à axe horizontal opérant en régime stationnaire, en utilisant le code ‘Fluent’. L’objectif principal est de déterminer les caractéristiques aérodynamiques de la pale en état d’arrêt et en rotation. Les simulations ont été effectuées en considérant les équations de Navier-Stokes moyennées par la procédure de Reynolds. Un maillage non-structuré a été adopté et en utilisant la technique ‘moving reference frame’. Le modèle de turbulence Spalart-Allmaras a été utilisé pour décrire l’écoulement turbulent. Les résultats de simulations ont été comparés avec ceux du l’expérimental, pour les conditions à la fois fixe et en rotation. En général, de bonnes concordances ont été notées.]]>

استسمح الملتقى أن أعطيه مثالا على إحدى المسائل اللغوية التى لا تفتأ معقدة و شائكة في قواعد اللغة العربية ، و أعني بها هنا صيغة او بنية الفعل المجرد الرباعي و علاقة كل هذا بما هو زائد على ثلاثة أصوات .]]>
Une maison écologique, désigne plus un concept qu’un type défini d’habitation. L’idée est de combiner les différents modes de chauffage, de ventilation, d’alimentation des appareils pour réduire massivement la consommation d’énergie, donc une décroissance exponentielle du rejet de CO2. Le travail présenté est l’étude de l’impact d’une maison écologique sur l’environnement. Afin d’aboutir à ce bilan, il faudrait d’abord faire une étude globale sur le bilan énergétique, à partir duquel nous pourrons connaître d’un coté le temps d’utilisation de chaque équipement de la maison, donc un bilan sur le rejet de CO2 et de l’autre coté, la comptabilisation du carbone dans l’énergie primaire, ainsi que le cycle de vie des matériaux d’isolation. Les résultats obtenus ont été confrontés aux résultats de la même maison construite avec des matériaux non isolants, tels que la brique, le béton… La confrontation montre une différence significative sur les plans énergétique, économiques, ainsi qu’environnementaux, ce qui nous laisse très optimistes sur le rendement des habitats écologiques.]]>
