In this work, we present a novel power penalty method for the approximation of a global solution to a double obstacle complementarity problem involving a semilinear parabolic differential operator and a bounded feasible solution set. We first rewrite the double obstacle complementarity problem...

We investigated the mean-free path effects on the magnetoresistance of ferromagnetic nanocontacts. For most combinations of parameters the magnetoresistance monotonously decreases with increasing the contact cross-section. However, for a certain choice of parameters the calculations show...

A computer model has been developed and validated using extensive data for air-air, water-water, and water-air heat pumps with enhanced surface-tubing heat exchangers. Good agreement between numerical and experimental results was observed. Based on numerical data obtained from the computer...
