Characterizing and modeling cyclic behavior in non-stationary time series through multi-resolution analysis
Dilip P. Ahalpara, Amit Verma, Prasanta K. Panigrahi +1
A method based on wavelet transform and genetic programming is proposed for characterizing and modeling variations at multiple scales in non-stationary time series. The cyclic vari…
On Estimation of Hurst Scaling Exponent through Discrete Wavelets
P. Manimaran, Prasanta K. Panigrahi, Jitendra C. Parikh
We study the scaling behavior of the fluctuations, as extracted through wavelet coefficients based on discrete wavelets. The analysis is carried out on a variety of physical data s…
Wavelet analysis of event by event fluctuations
P. Manimaran, Prasanta K. Panigrahi
The temporal fluctuations of produced hadron density in heavy ion collisions, modelled by 2D Ising model at temperatures and below, are studied through a recently developed w…
