Photovoltaic solar cell simulation of shockley diode parameters in matlab
In this work, the Shockley diode parameters were simulated using the Matlab software package with the solar cell I - V and P - V characteristics in focus. Our model has been based on previous studies while the effects of varying cell temperature, series resistance, Rs ambient irradiation and diode quality factor were put into consideration and the output current and power characteristics of the PV model simulated,...

Novel nano photocatalyst for the degradation of sky blue 5b textile dye
A new Nano photocatalyst, CuO-Al2O3-ZrO2-TiO2 was synthesized by co-precipitation for the removal of textile dye under ultra violet and direct sunlight. The synthesized catalyst was characterized by using X-rays diffraction, X-rays fluorescent, thermo gravimetric analysis, DRS, scanning electron microscopy and EDX. The dopants reduced the recombination of ecb- and hvb+ and decreased the band gap of...

Polyaniline/Fe3O4 coated on MnFe2O4 nanocomposite: Preparation, characterization, and applications in microwave absorption
Conductive polyaniline (PANi)/Fe3O4 is coated on the MnFe2O4 nanocomposite with multi core shell structure was synthesized by in-situ polymerization in the presence of dodecyl benzene sulfonic acid (DBSA) as the surfactant and dopant and ammonium persulfate (APS) as the oxidant. The structure and magnetic properties of Fe3O4 coated on the MnFe2O4 nanoparticles were studied by using powder...

Electrical characterization of conducting poly(2-ethanolaniline) under electric field
We have studied conductivity and molecular weight obtained poly(2-ethanolaniline), P2EANi. P2EANi synthesized according to the best ratio of obtained molar of initiator to monomer at different reaction times. Then we measured the mass and conductivity of the obtained polymers in the best time of polymerization. Next, we repeated these reactions under different electric fields in the most appropriate time and measured...

A Mode-I crack problem for two-dimensional problem of a fiber-reinforced thermoelastic with normal mode analysis
The aim of the present work is to investigate the influence of the Mode-I crack on the plane waves in a linearly ï¬ber-reinforced. A general model of the equations of coupled theory (CD) and Lord-Shulman (L-S) theory with one relaxation time are applied to study the influence of reinforcement on the total deformation for an infinite space weakened by a finite linear opening Mode-I crack is solving. The material is...

The improved Riccati equation mapping method for constructing many families of exact solutions for a nonlinear partial differential equation of nanobiosciences
In this paper we apply the improved Riccati equation mapping method to construct many families of general exact solutions of a nonlinear partial differential equation involving parameters of special significant for nanobiosciences and biophysics, namely, the equation of nano-ionic currents along microtublues. Comparison between our new results and the well-known results are given. The nonlinear equation elaborated here...

Decentralized management of a multi-source electrical system: A multi-agent approach
The objective of this paper was design and implementation of a self-adaptive management system of a set of production sources in a changing and unpredictable energy demand environment. The strategy proposed made it possible to achieve optimal management of the energy resource production of the electrical system facing the changing demand. After showing the need to follow «intelligently» the behavior of...
