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…

Stochastic resonance as a filter for signal detection from multisignal inputs
K P Harikrishnan, G Ambika
We undertake a detailed numerical study of the phenomenon of stochastic resonance with multisignal inputs. A bistable cubic map is used as the model and we show that it combines th…

A non subjective approach to the GP algorithm for analysing noisy time series
K. P. Harikrishnan, R. Misra, G. Ambika +1
We present an adaptation of the standard Grassberger-Proccacia (GP) algorithm for estimating the Correlation Dimension of a time series in a non subjective manner. The validity and…
