Etched Glass Surfaces, Atomic Force Microscopy and Stochastic Analysis
G. R. Jafari, M. Reza Rahimi Tabar, A. Iraji zad +1
The effect of etching time scale of glass surface on its statistical properties has been studied using atomic force microscopy technique. We have characterized the complexity of th…
Controlling surface statistical properties using bias voltage: Atomic force microscopy and stochastic analysis
P. Sangpour, G. R. Jafari, O. Akhavan +2
The effect of bias voltages on the statistical properties of rough surfaces has been studied using atomic force microscopy technique and its stochastic analysis. We have characteri…
The Effect of Annealing Temperature on Statistical Properties of Surface
G. R. Jafari, A. A. Saberi, R. Azimirad +2
We have studied the effect of annealing temperature on the statistical properties of surface using atomic force microscopy techniques (AFM). We have applied both level cross…
Level Crossing Analysis of the Stock Markets
G. R. Jafari, M. S. Movahed, S. M. Fazeli +2
We investigate the average frequency of positive slope , crossing for the returns of market prices. The method is based on stochastic processes which no scaling feature is…
Multifractal Detrended Fluctuation Analysis of Sunspot Time Series
M. Sadegh Movahed, G. R. Jafari, F. Ghasemi +2
We use multifractal detrended fluctuation analysis (MF-DFA), to See query 1 study sunspot number fluctuations. The result of the MF-DFA shows that there are three crossover timesca…
Two-Scale Kirchhoff Theory: Comparison of Experimental Observations With Theoretical Prediction
G. R. Jafari, P. Kaghazchi, R. S. Dariani +4
We introduce a non-perturbative two scale Kirchhoff theory, in the context of light scattering by a rough surface. This is a two scale theory which considers the roughness both in…
