Author:Lebelo, RS; Fedotov, I; Shatalov, MDate:Sep 2008In this paper, the method of approximating solutions of partial differential equations with variable coefficients is studied. This is done by considering heat flow through a one-dimensional model with variable cross-sections. Two cases are ...Read more
