Numerical analysis of symple grounding systems

[Tanex]

Hi
I'm Looking for any information about numerical analysis of grounding systems, soils with one or two layers of resistivity.
I need to find were donwload the next papers:

1. "Analysis of grounding systems". A. P. Meliopoulos, R.P. Webb and E. B. Joy. IEEE transactions on power apparatus and systems, Vol. Pas100, Nº3, pp. 1039-1048, March 1981.

2. "Computation of potencial at surface above an energized grid or other electrodes, allowing for non uniform current distribution". R. J. Heppe. IEEE transactions on power apparatus and systems, Vol. Pas98, Nº6, pp. 1978-1989, November-December 1978.

Any information please!!!!!!! is for my Titulation Work.

Thanks
