This review addresses a central question in the field of complex systems: given a fluctuating
(in time or space), sequentially measured set of experimental data, how should one analyze …

In this paper we study the footprint of cosmic string as the topological defects in the very
early universe on the cosmic microwave background radiation. We develop the method of …

We have used level crossing analysis to obtain further insights on roughness and
multifractality. In addition, sources of multifractality could be specified by using shuffling and …

We investigate the average frequency of positive slope ν α+ crossing for the returns of
market prices. The method is based on stochastic processes in which no scaling feature is …

We have studied the effect of annealing temperature on the statistical properties of WO 3
surface using atomic force microscopy (AFM) techniques. We have applied both level …

The effect of etching time on the statistical properties of hydrophilic surfaces of
SiO2/TiO2/glass nano bilayers has been studied using atomic force microscopy (AFM) and a …

In this paper, we investigate the crossing statistics of speckle patterns formed in the Fresnel
diffraction region by a laser beam scattering through a nanofluid. We extend zero-crossing …

Previously we derived the probability density function (PDF) of the zero-crossing interval for
1/f α noise and found that the PDF, L (t) obeys the power law of the form 1/tc whose …

The effect of etching time on the statistical properties of the hydrophilic surface of
SiO_2/TiO_2/Glass nano bi-layer has been studied using Atomic Force Microscopy (AFM) …

In this paper, we are planning to consider the fluctuations of two nonlinear equations which
govern the dynamics of water waves named Camassa–Holm and KdV. We consider the total …
