Solving an inverse heat conduction problem by reduced differential transform method

In this paper, ?the inverse problem of determining an unknown boundary condition in an inverse heat conducton problem is considered. ?The reduced differential transform method is presented for recovering the unknown functions and obtaining a solution of the problem?. ?This technique doesn't require? ?any discretization?, ?linearization or small perturbations. ?Finally?, ?some examples are presented to illustrate the ability and efficiency of the present approach.
