A robust experimental-based artificial neural network approach for photovoltaic maximum power point identification considering electrical, thermal and meteorological impact by Gowid, Samer

“…Nonetheless, the consideration of irradiance, electrical, thermal, and weather parameters (scenario IV) yielded higher identification accuracy. The results showed a decrease in the MSE of Vmp by 74.3% (from 1.6 V to 0.411 V), and in the MSE of Imp by 95% (from 4.4e−6 A to 2.16e−7 A), respectively. …”

The role of type II FB (I):Tl+ defect in laser light generation and color image formation at the low coordination surface sites of AgBr: Ab initio calculations by Shalabi, A.S.

“…All relaxed excited states of the defect containing surfaces were deep below the lower edges of the conduction bands of the ground-state defect-free surfaces indicating that type II FB(I):Tl+ is suitable laser defect. The probability of orientational destruction of the two centers, attributed to the assumed saddle point ion configurations along the 〈1 1 0〉 axis, was found to decrease as the coordination number of the surface ions decreases. …”
