A coordinate-splitting economic diierence scheme is proposed for generalized parabolic equations (GPE) containing fourth-order diiusion operators and the algorithm for its implementation is developed. The performance of the scheme is demonstrated for diierent cases, e.g. for treating bifurcation phenomena. The technique is applied to the numerical solution(More)
This paper introduces a relative structural complexity measure for the characterization of disordered surfaces. Numerical solutions of 2d+1 KPZ equation and scanning force microscopy (SFM) patterns of porous silicon samples are analyzed using this methodology. The results and phenomenological interpretation indicate that the proposed measure is efficient(More)
