Features in the Primordial Spectrum from WMAP: A Wavelet Analysis
Arman Shafieloo, Tarun Souradeep, P. Manimaran +2
Precise measurements of the anisotropies in the cosmic microwave background enable us to do an accurate study on the form of the primordial power spectrum for a given set of cosmol…
1/f noise and multifractality in atmospheric-CO2 records
Prabir K. Patra, M. S. Santhanam, P. Manimaran +2
We study the fluctuations in the measured atmospheric CO2 records from several stations and show that it displays 1/f noise and multifractality. Using detrended fluctuation analysi…
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.…
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…
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…
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…
