Modeling Time Series Data of Real Systems
Dilip P. Ahalpara, Jitendra C. Parikh
Dynamics of complex systems is studied by first considering a chaotic time series generated by Lorenz equations and adding noise to it. The trend (smooth behavior) is separated fro…

Coherence Resonance in an Autapse Neuron Model with Time Delay
Gautam C Sethia, Juergen Kurths, Abhijit Sen
We study the noise activated dynamics of a model {\it autapse} neuron system that consists of a subcritical Hopf oscillator with a time delayed nonlinear feedback. The coherence of…

Excitable Dynamics in the Presence of Time Delay
Gautam C Sethia, Abhijit Sen
The spiking properties of a subcritical Hopf oscillator with a time delayed nonlinear feedback is investigated. Finite time delay is found to significantly affect both the statisti…
