Spectral fluctuation characterization of random matrix ensembles through wavelets
P. Manimaran, Prasanta K. Panigrahi, P. Anantha Lakshmi
A recently developed wavelet based approach is employed to characterize the scaling behavior of spectral fluctuations of random matrix ensembles, as well as complex atomic systems.…
Correlations and periodicities in Himalayan tree ring widths and temperature anomalies through wavelets
Prasanta K. Panigrahi, P. Manimaran, Ananth Lakhmi +1
We have studied periodicities and correlation properties of tree ring width chronology of deodar tree from Joshimath (1584 - 1999 years) and Uttarkashi (1500 - 2002 years) in the w…
Difference in nature of correlation between NASDAQ and BSE indices
P. Manimaran, Prasanta K. Panigrahi, Jitendra. C. Parikh
We apply a recently developed wavelet based approach to characterize the correlation and scaling properties of non-stationary financial time series. This approach is local in natur…
Multiresolution analysis of fluctuations in non-stationary time series through discrete wavelets
P. Manimaran, Prasanta K. Panigrahi, Jitendra C. Parikh
We illustrate the efficacy of a discrete wavelet based approach to characterize fluctuations in non-stationary time series. The present approach complements the multi-fractal detre…
Wavelet analysis and scaling properties of time series
P. Manimaran, Prasanta K. Panigrahi, Jitendra C. Parikh
We propose a wavelet based method for the characterization of the scaling behavior of non-stationary time series. It makes use of the built-in ability of the wavelets for capturing…
