Etude technico-économique d’un système hybride (aérogénérateur et moteur diesel) pour la production d’électricité.

Technico-economic study of a hybrid system (Aerogenerator and Diesel engine) for the electricity productionIn this article one is interested in the technico-economic study of a hybrid system (aerogenerator and Diesel engine) on the site of Tlemcen by using the data of measurement of the stations of the ONM (National office of Meteorology), one evaluates the annual aver  age power available on the site as well as the annual average power provided by the aerogenerator and the diesel engine thus the determination of the number of hearths which can be to feed in electric power finally this study continues with an economic aspect because the development of the aerogenerators and the diesel engines come under the technical field but also of the economic field, so that the production of electrical energy is viable that is to say less low than that of that produced by a Diesel engine or a turbine, the output and the cost are two factors dependent between them. The viability of the installation would be little interest for an output and a cost of high cost or for an output and a weak cost of cost

Dunkl-Pauli Equation

The Pauli equation, an important equation of quantum mechanics, allows us to study the dynamics of spin-$1/2$ particles. The Dunkl derivative, when used instead of the ordinary derivative, allows us to obtain parity-dependent solutions. In this work, we consider a two-dimensional nonrelativistic spin-$1/2$ particle system in the presence of an external magnetic field, and we explore the system's dynamics by solving the Pauli equation in the Dunkl formalism analytically. Then, we assume the system to be in thermal equilibrium, so that, we examine various thermal quantities of the system.Comment: 10 pages, 8 figure

Extended uncertainty principle and Van der Waals black holes

In this manuscript, we investigate the extended uncertainty principle (EUP) effects on the Van der Waals (VdW) black holes whose thermal quantities mimic the VdW liquid. We find that the considered formalism imposes an upper bound on the event horizon radius. Thus, the mass, Hawking temperature, and heat capacity become physically meaningful within a certain range of event horizon radii. At a large event horizon radius the black hole has a remnant. Whether the VdW black hole is stable or not depends on the black hole parameters.Comment: 13 pages, 10 figure

Van der Waals black holes in rainbow gravity

Recently, Rajagapol et al presented an asymptotically AdS black hole metric whose thermodynamics qualitatively mimics the behavior of the Van der Waals fluid by treating the cosmological constant as a thermodynamic pressure. In some studies in the literature, authors have discussed the effects of deformed algebras such as generalized and extended uncertainty principles on the thermal quantities of these black holes. In this manuscript, we considered another deformation, the rainbow gravity formalism, and we investigated its impact on the Van der Waal black hole thermodynamics. To this end, we first generated the modified lapse and mass functions, and then we derived the modified thermal quantities such as thermodynamic volume, Hawking temperature, entropy, and specific heat functions. Finally, we explored the thermodynamics of a black hole, which mimics the thermodynamics of an ideal gas, under the influence of the rainbow gravity formalism.Comment: 7 figures, 16 page

Some new Hermite–Hadamard type inequalities for functions whose nth derivatives are convex

We first create an integral identity for n-times differentiable functions. Relying on this identity, we establish some new Hermite–Hadamard type inequalities for functions whose nth derivatives are convex

Input Frequencies Optimization Based on Genetic Algorithm for Maximal Mutual Information

Among encountered problems in digital and analog communications, there is mismatch between canals and sources. As regards theory of information, unfortunately, this mismatch found expression in information loss during transfer to reception side. In order to settle the problem, the solution consists in adjustment of probability law at source so that we maximize the mean mutual information. For a little number of symbols, either at emission or at reception, the work can be done analytically with some difficulties. Unfortunately, the problem have tendency to become more and more difficult and complicated as number of symbols increases. In this case and as alternative, we propose a non-traditional optimization method, namely genetic algorithm, which will express, with regard to our problem, all its efficiency through this paper with some conclusive applications

Effects due to a scalar coupling on the particle-antiparticle production in the Duffin-Kemmer-Petiau theory

The Duffin-Kemmer-Petiau formalism with vector and scalar potentials is used to point out a few misconceptions diffused in the literature. It is explicitly shown that the scalar coupling makes the DKP formalism not equivalent to the Klein-Gordon formalism or to the Proca formalism, and that the spin-1 sector of the DKP theory looks formally like the spin-0 sector. With proper boundary conditions, scattering of massive bosons in an arbitrary mixed vector-scalar square step potential is explored in a simple way and effects due to the scalar coupling on the particle-antiparticle production and localization of bosons are analyzed in some detail
