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…

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…
