Analysis of radioactive waste contamination in soils. Part IV: solution via symbolic manipulation

The goal of this paper is to demonstrate the automatic symbolic-numerical solution of the one-dimensional linearized Burgers equation with linear decay, which models the migration of radionuclides in porous media, by using the generalized integral transform technique and the Mathematic system. An example is considered to allow for comparison between the proposed hybrid numerical-analytical solution and the exact solution. Different filtering strategies are also investigated, in terms of the effects on convergence rates. (author)
