 In this paper, we construct the solution expressions of fourth order nonlinear difference systems

Φn+1       =                   Φn−2Ψn−3                       ,
        α + Ψn (±1 ± Γn−1Φn−2Ψn−3)
Ψn+1       =                  …

The fractional-order derivative of a non-constant periodic function is not periodic with the same period. Consequently, any time-invariant fractional-order systems do not have a non-constant periodic solution. This property limits the applicability…

This paper studies some weighted norm inequalities related to some Calderon-Zygmund singular integrals. Applications to the Sobolev-Gagliardo-Nirenberg inequality, differential forms, and the potential equation du= f are given.

CuInSe2 thin films (CIS) are fabricated by flash evaporation in vaccum from a single source. Their optical properties are investigated by spectrophotometry in the range 0.3-2.5 . The interpretation of these results are based on the Mueller numerical…

Mircocrystalline silicon solar cells based on pin and nip layer sequences require an effective light trapping in the near infrared (NIR) to enhance the long wavelength spectral response. Therefore, the effect of interface roughness on the optical…

An optimization method is proposed and applied to study a PV-electrolyzer system consisting of Solarex MSX60 modules and PEM electrolyser H-Tec StaXX7 stacks. A total of 41 series-parallel combinations of PV modules and electrolyser stacks were…

Due to the increase of the demand for electrical power and the gaining of momentum of decentralized electrical production, the importance of microgrids is increasing constantly. Therefore, it is pertinent to understand how microgrids work and develop…

In this paper, a genetic algorithm is used for the optimization and tuning of PI controller parameters in order to improve the performance of SVC compensator in both dynamic and static response. The efficiency of the proposed method has been studied…
