Aims: Analytical modeling of the combined systems photovoltaic-thermoelectric (PV + TEG). The advantage of these systems is double: − On the one hand, they allow to cool the photovoltaic cells (PV), which avoids the loss of electrical efficiency observed in the devices...

Let R be a ring with involution ′∗′ . An additive map x → x* of R into itself is called an involution if (i) (xy)*= y∗x∗ and (ii) (x∗)∗ = x holds for all x,y ∈ R. An additive mapping δ: R → R is called a derivation if δ(xy) = δ(x)y + xδ(y) for all x, y ∈ R. The purpose of this pa...

In this article, we suggest a new approach while solving Dual simplex method using Quick Simplex Method. Quick Simplex Method attempts to replace more than one basic variable simultaneously so it involves less iteration or at the most equal number than in the standard Dual Simple...

The predictive estimator of the gradient in simple regression is assumed to be the product of the gradient given by least-squares fitting and a constant (ρ). The results of numerical simulations show that when generalized cross-validation is used to obtain the optimal ρ, the resu...
