The functional identification approach for numerical reconstruction of the temperature-dependent thermal-conductivity coefficient

The functional identification approach of the thermal-conductivity coefficient for the unsteady-state nonlinear heat-conduction equation is considered. Unlike traditional methods, the proposed algorithm does not utilize approximations of the coefficient with the aid of the specified system of basis...

Beschreibung
Zusammenfassung:	The functional identification approach of the thermal-conductivity coefficient for the unsteady-state nonlinear heat-conduction equation is considered. Unlike traditional methods, the proposed algorithm does not utilize approximations of the coefficient with the aid of the specified system of basis functions. The results of computational experiments are presented.
