SOLVING THE BACKWARD HEAT CONDUCTION PROBLEM BY DATA FITTING WITH MULTIPLE REGULARIZING PARAMETERS
《Journal of Computational Mathematics》2012年第4期418-432,共15页Qun Chen Jijun Liu 
Acknowledgments. This work is supported by NSFC (No.11071039) and Natural Science Foundation of Jiangsu Province (No.BK2011584).
We propose a new reconstruction scheme for the backward heat conduction problem. By using the eigenfunction expansions, this ill-posed problem is solved by an optimization problem, which is essentially a regularizing ...

A NEW APPROACH AND ERROR ANALYSIS FOR RECONSTRUCTING THE SCATTERED WAVE BY THE POINT SOURCE METHOD被引量:2
《Journal of Computational Mathematics》2007年第2期113-130,共18页Jijun Liu Gen Nakamura Roland Potthast 
Supported NSFC(No.10371018).
Consider an inverse scattering problem by an obstacle D belong to R^2 with impedance boundary. We investigate the reconstruction of the scattered field u^s from its far field pattern u^∞ using the point source method...
