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…
Intermittency and Synchronisation in Gumowski-Mira Maps
G Ambika, K Ambika
The Gumowski-Mira map is a 2-dimensional recurrence relation that provide a large variety of phase space plots resembling fractal patterns of nature. We investigate the nature of t…
Synchronisation schemes for two dimensional discrete systems
G Ambika, K Ambika
In this work we consider two models of two dimensional discrete systems subjected to three different types of coupling and analyse systematically the performance of each in realisi…
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…
The non-linear behavior of the black hole system GRS 1915+105
R. Misra, K. P. Harikrishnan, G. Ambika +1
Using non-linear time series analysis, along with surrogate data analysis, it is shown that the various types of long term variability exhibited by the black hole system GRS 1915+1…
