ABSTRACT
A Markovian Random-Walk approach is used to obtain the partial
differential equation of a diffusive one-dimensional and bi-dimensional
process, modeled as particles passing walls with certain probability
of refl ecting or passing along. An analytical solution is deduced and
compared with a fi nite difference approach solved with MATLAB;
further considerations of numerical solution under the CUDA
architecture are presented in this chapter.

Diffusive problems appear in many ...
