Objective: Biochemical and haematological parameters of nutritional interest were determined in the serum of opiate addicts in order to compare them with those obtained in healthy subjects. Linear ...

We investigate issues of numerical solving of optimal control problems for second order elliptic equations with non-self-adjoint operators - convection-di usion problems. Control processes are ...

We present a new fully discrete method to solve a linear variable coefficient parabolic equation on a rectangular region. The scheme is an alternating direction implicit method which uses the third ...
