This study proposes and implements maximum power Point Tracking (MPPT) control on thermoelectric generation system using an extremum seeking control (ESC) algorithm. The MPPT is applied to guarantee maximum power extraction from the TEG system. The work has been carried out through modelling of thermoelectric generator/dc-dc converter system using Matlab/Simulink. The effectiveness of ESC techn...

Illumination non-homogeneity is the main problem which affects dense-array CPV systems. In a previous work we theoretically showed that connecting each cell in the array to a DC–DC converter module, leads to an increase of the power transfer efficiency with respect to classical series connection. This finding is here confirmed by two experiments making use of a cells’ array, one for a certain c...

a dynamic two dimensional problem of thermoelasticity with double porous structure has been considered to investigate the disturbance due to normal force and thermal source. laplace and fourier transform technique is applied to the governing equations to solve the problem. the transformed components of stress and temperature distribution are obtained .the resulting expressions are obtained in t...

“wild thorns” is a novel written by the palestinian novelist sahar khalifeh; it focuses on the colonisation of palestine from a feminist point of view. she considers the israeli colonisation as a patriarchy. this paper aims at investigating two types of colonization that have been represented in the form of patriarchy in the novel. the investigation of the issue of palestine from a feminist poi...

The output voltage obtained from renewable energy sources is low and needs to be stepped up by and order of 20 for practical usage or grid integration.This emphasizes the need for high gain DC-DC converters. The proposed DC-DC converter topology combines the simple boost converter and a coupled inductor with voltage double stages to provide high voltage gain. The main advantages of this topolog...

The double balance mixer scheme in-phase signal input and double-quadrature Local Oscillator (LO) is suggested for application on IQ direct conversion receivers. The influence of the gain and phase mismatches of splitters is investigated. It is shown that a similar scheme using square-law detectors is promising on optical applications. Introduction The increasing interest in direct conversion r...

in the present paper, we prove subordination, superordination and sandwich-type properties of a certain integral operators for univalent functions on open unit disc, moreover the special behavior of this class is investigated.
