The Transient Photoconductivity (TPC) is studied in the pre-recombination time range on the basis of a Multiple Trapping (MT) model which uses a trans...

The reversible interaction between molecular oxygen and hydrogenated amorphous silicon or polycrystalline silicon surfaces is studied. Coplanar config...

Electronic structure calculations of zinc-blende Cd1-xMnxTe alloys have been performed by using the empirical pseudopotential method. The initial form...

The paper presents a new approach for solving the optimal power flow problem. The problem is solved by a sequential unconstrained minimization techniq...

The aim of this work is to analyse the performance of different photovoltaic water pumping systems. The Typical Meteorological Year (TMY) data from fo...
