Computing the multifractal spectrum from time series: An algorithmic approach
K. P. Harikrishnan, R. Misra, G. Ambika +1
We show that the existing methods for computing the f(α) spectrum from a time series can be improved by using a new algorithmic scheme. The scheme relies on the basic idea that the…
X-ray variability of AGNs in the soft and the hard X-ray bands
V. R. Chitnis, J. K. Pendharkar, D. Bose +3
We investigate the X-ray variability characteristics of hard X-ray selected AGNs (based on Swift/BAT data) in the soft X-ray band using the RXTE/ASM data. The uncertainties involve…
Parametric characterisation of a chaotic attractor using two scale Cantor measure
K P Harikrishnan, R Misra, G Ambika +1
A chaotic attractor is usually characterised by its multifractal spectrum which gives a geometric measure of its complexity. Here we present a characterisation using a minimal set…
