In this paper, we introduce a wave transport scenario useful for investigation of spatio-temporal energy transport related to earthquake phenomena. We perform gradient pattern analysis (GPA) of convection–diffusion patterns given by the solution of 2D Burger's equation. The GPA leads to...

A gradient pattern analysis is used to report a phenomenogical evidence of asymmetric nonlinear spatial distribution of porous silicon structures. We used a canonical sample set obtained from scanning force microscopy. Due to the high sensitivity of the gradient field operator, it is possible to...

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...
