In this paper, we developed Quintic and Septic C2C2-spline methods for solving initial fractional differential equations. The convergence analysis of the methods is discussed. Illustrative examples are included to demonstrate the validity and applicability of the presented techniques. Our numerical results were compared with those in the recent literature.]]>
The key objective of this work is to create a comprehensive comparison between experimental analysis methods for detecting crosslinking reaction in EVA encapsulant material during PV module fabrication process. Several analytical methods, spanning from classical gel content extraction measurements over different thermo-analytic and mechanical approaches to spectroscopic analysis as Thermally Stimulated Current (TSC), have been investigated as to their ability to reveal the crosslinking state of ethylene vinyl acetate (EVA). The basic results show that TSC complements perfectly other thermal analysis methods like as Differential Scanning Calorimetry (DSC), Dynamic Mechanical Thermal Analysis (DMTA) to determine fundamental properties of EVA such as molecular mobility characteristics and also to monitor the crosslinking reaction. Exothermic peak as revealed by DSC analysis can be used to estimate the crosslinking rate of EVA during PV module encapsulation process as fast quality control test.]]>

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.]]>
Le présent travail porte sur l’étude de faisabilité d’appliquer la technique de réfrigération magnétique (RM) à la liquéfaction du gaz naturel (c’est-à-dire, liquéfacteur magnétique). Il s’agit de modéliser le phénomène de la réfrigération magnétique, de proposer un prototype de liquéfacteur magnétique et d’évaluer les performances du système. Un tel dispositif consiste essentiellement en un régénérateur magnétique, un fluide caloporteur et une source de champ magnétique. La première partie du travail portait sur la modélisation du phénomène de RM à travers l’étude d’un cycle thermomagnétique en considérant les équations d’énergie gouvernant les échanges de chaleur entre le fluide et le solide dans le régénérateur magnétique. La deuxième partie a été consacrée à l’analyse de performance et au dimensionnement du liquéfacteur magnétique. A cet effet, à l’aide du logiciel de simulation Hysys, de nombreuses configurations du liquéfacteur magnétique ont été proposées et étudiées, et ce, afin de déterminer les configurations optimales susceptibles de produire d’appréciables quantités de gaz naturel liquéfié (GNL). Des configurations hautement efficaces ont été trouvées; des performances ayant des valeurs jusqu’à 81% de celle du cycle de Carnot correspondant. Toutefois, en comparaison avec des liquéfacteurs conventionnels à gaz, les débits de GNL trouvés sont limités; des valeurs inférieures à 4.85 kg/jour obtenues sous des hautes pressions d’opération du gaz naturel (de l’ordre 36 bars) et pour un champ magnétique appliqué de 5 T.]]>

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.]]>
In this work we studied the behavior of the photovoltaic panels in a uniform and non uniform illumination conditions on the module surface. For this a group of UDTS50 PV panels was modeled and simulated under Matlab/Simulink environment toward discuss and compare the external characteristics in the two studied situations. The simulation results obtained shows well the effect of the shadow in a photovoltaic installation, which requires particular precautions in order to guarantee the maximum power possible under all operation conditions.]]>

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.]]>
L’étude analytique et la recherche expérimentale sur la réflexion des ondes de choc asymétriques (interférences RR - MR), dans les écoulements supersoniques stationnaires a été rapporté pour la première fois par, Li et al. [1]. Le but de ce travail de recherche est d’effectuer des simulations numériques (CFD), sur les interférences des ondes de choc dans les écoulements supersoniques stationnaires et plus particulièrement à l’étude de la transition réflexion régulier (RR) vers réflexion de Mach (MR) et vice versa - phénomène hystérésis. Ce dernier procédé a été largement étudié numériquement dans le cas des réflexions symétrique au cours des ces dernières années. L’analyse des résultats obtenus a été basée sur des résultats expérimentaux de Li et al. [1], et comparés analytiquement par la théorie du triple choc (polaire de choc). L’étude théorique a permis l’identification des critères de transition, et montre clairement l’existence d’un phénomène hystérésis dans la transition (RR) - (MR) des ondes de choc asymétriques analogue à celui existant en interaction de choc symétrique.]]>

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.]]>
This paper deals with the experimental study of two box-type solar cookers equipped with booster mirrors and suitable for cooking a single family’s food. The first one has a conventional, ordinary horizontal aperture area and the second one has an inclined aperture area. The latter is a new configuration which allows for much higher solar radiation interception, resulting in better cooking performance, especially in the winter when the sun’s elevation is low. Optimum inclination angles of the booster mirrors were calculated in order to maximize the reflection of the solar rays on the absorber plates. The cooking performance of the proposed new cooker was compared with the conventional box solar cooker of the same material and surface during Winter 2013 in the Ghardaîa Sahara climate (32.39°N, 3.78°E), Algeria. According to the values of some essential thermal performance parameters suggested by International Standards and evaluated by experimental studies, the inclined aperture area improves the thermal performance of the box-type solar cooker remarkably, reducing cooking time considerably. The first and second figures of merit for the improved cooker, respectively, were 0.15 and 0.47 compared to 0.13 and 0.38 for the conventional cooker.]]>

In this work, we consider the nonparametric estimation of the probability density function for nonnegative heavy-tailed (HT) data. The objective is first to propose a new estimator that will combine two regions of observations (high and low density). While associating a gamma kernel to the high-density region and a BS-PE kernel to the low-density region. Then, to compare the proposed estimator with the classical estimator in order to evaluate its performance. The choice of bandwidth is investigated by adopting the popular cross-validation technique and two variants of the Bayesian approach. Finally, the performances of the proposed and the classical estimators are illustrated by a simulation study and real data.]]>
Le Bénin ne possède pas des sources de production d’énergie électrique propre à lui-même. Ceci explique sa dépendance énergétique des pays voisins. Pourtant il possède sur sa côte, dans le Golfe de Guinée, une propagation d’un vent quasi permanent et régulier. Une solution avantageuse pour ce pays et la sous-région est la récupération et la transformation de l’énergie éolienne en énergie électrique. Connaissant l’expression de la puissance éolienne [3], celles de la masse volumique de l’air sec [4, 13] et de l’air humide [13], ainsi que celle de l’humidité relative [4, 13], nous avons établi l’expression du coefficient qui montre l’impact de la température, de la pression et de l’humidité relative sur la puissance éolienne. Avec les mesures faites par le projet ‘Millénium Challenge Account (MCA-Bénin)’ en 2011 dans le cadre de l’extension du Port Autonome de Cotonou, nous avons montré l’action des trois paramètres ci-dessus cités sur la puissance éolienne à Cotonou au Bénin.]]>

This paper concerns the uniqueness and stability of an inverse problemin PDE. Our problem consists of identifying two parameters b(x)b(x) and c(x)c(x) in the following boundary-value problem
{Lu:=−b(x)u′′(x)+c(x)u′(x)=f(x),u(0)=u(1)=0,{Lu:=−b(x)u″(x)+c(x)u′(x)=f(x),u(0)=u(1)=0,
from distributed observations u1u1 (resp. u2u2) associated with the source f1f1 (resp. f2f2). For one observation, the solution is not unique. However, we prove, under some conditions, the uniqueness of the solution p=(b,c)p=(b,c) in the case of two observations. Furthermore, we derive a H\"older-type stability result. The algorithm of reconstruction uses the least squares method. Finally, we present some numerical examples with exact and noisy data to illustrate our method.]]>
Dans cette étude, nous présentons les résultats expérimentaux relatifs aux expériences menées sur des capteurs solaires plans à air. En premier lieu, nous décrivons les différentes configurations étudiées. De ce fait, nous avons opté à combiner trois solutions technologiques, à savoir, i) introduire différentes géométries de rugosités dans la veine d’air mobile, ii) inverser le sens de l’écoulement de l’air dans le capteur, iii) faire circuler le fluide caloporteur de part et d’autre de la plaque d’acier inférieure ‘double passage’. En deuxième phase, nous exposons les résultats qui traduisent l’influence des différentes solutions technologiques proposées sur les performances thermiques et la consommation électrique d’un capteur solaire en comparant les rendements thermiques et les pertes de charge pour tous les cas étudiés.]]>

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.

The use of naturally materials improves to reduce the life-cycle cost of building (initial cost plus lifetime energy cost). In this paper, looking for the thermal comfort inside an apartment located in an arid climate zone in Algeria, in Biskra city (35.56 N, 6.16 E) by comparing the use of two materials: the concrete (C) and the stabilized earth-concrete (SEC). The temperature variations through the walls are determinate and analyzed. In this study the wall is exposed to the maximum temperature in the two cases: transient and steady state. The mathematical formulation of the problem leads to a parabolic equation. The equation is resolved analytically and numerically by setting the appropriate boundary conditions. The resulting model applied for both materials (concrete, and SEC). The comparison of the results obtained, analytically and numerically, show that the SEC has the higher thermal resistance than concrete and the temperature difference between these two materials can reach about 5.5 °C in steady state. We have also performed the calculation of wall insulation dimensions by resolving a nonlinear system, which corresponds to the optimum thickness to ensure an adequate thermal comfort in side the flat.]]>

In this paper, we establish a new concentration inequality and complete convergence of weighted sums for arrays of rowwise linearly negative quadrant dependent (LNQD, in short) random variables and obtain a result dealing with complete convergence of first-order autoregressive processes with identically distributed LNQD innovations.]]>
Electrodeposited molybdenum oxide thin films are used as a buffer layer between the indium tin oxide (ITO) anode and the organic electron acceptor film in organic solar cells. The MoO3 films are deposited at room temperature using a solution of molybdic, acid and citric acid as complexing agents. Such electrodeposited MoO3 ultra thin films (10-20 nm) has been used as buffer layer (BF) in ITO/BF/copper phthalocyanine (CuPc)/fullerene (C60)/ aluminium tri (8-hydroxyquinoline) (Alq3)/ aluminium photovoltaic cells. It is shown that this electrodeposited MoO3 buffer layer enhances the charge transfer from CuPc to ITO through a decrease of the effective barrier, present at the interface CuPc/ITO. This improving effect is directly highlighted by the shape of the J-V curves. The kink effect, due to the barrier present at the interface ITO/organic, disappears when the electrodeposited molybdenum oxide buffer layer, is introduced at this interface, which testifies of the decrease of the barrier.]]>
