The Solution of Backward Heat Conduction Problem with Piecewise Linear Heat Transfer Coefficient [PDF]
In the fields of continuous casting and the roll stepped cooling, the heat transfer coefficient is piecewise linear. However, few papers discuss the solution of the backward heat conduction problem in this situation.

Determination temperature of a heat equation from the final value data [PDF]
We introduce the truncation method for solving a backward heat conduction problem. For this method, we give the stability analysis with new error estimates. Meanwhile, we investigate the roles of regularization parameters in these two methods.
