Parametric excitation and Hopf bifurcation analysis of a time delayed nonlinear feedback oscillator
Sandip Saha, Gautam Gangopadhyay, Sangeeta Kumari +1
In this paper, an attempt has been made to understand the parametric excitation of a periodic orbit of nonlinear oscillator which can be a limit cycle, center or a slowly decaying…
Systematic designing of bi-rhythmic and tri-rhythmic models in families of Van der Pol and Rayleigh oscillators
Sandip Saha, Gautam Gangopadhyay, Deb Shankar Ray
Van der Pol and Rayleigh oscillators are two traditional paradigms of nonlinear dynamics. They can be subsumed into a general form of Liénard--Levinson--Smith(LLS) system. Based on…
Suppressing birhythmicity by parametrically modulating nonlinearity in limit cycle oscillators
Sandip Saha, Sagar Chakraborty, Gautam Gangopadhyay
Multirhythmicity, a form of multistability, in an oscillator is an intriguing phenomenon found across many branches of science. From an application point of view, while the multirh…
A Genetic Algorithm based Kernel-size Selection Approach for a Multi-column Convolutional Neural Network
Animesh Singh, Sandip Saha, Ritesh Sarkhel +3
Deep neural network-based architectures give promising results in various domains including pattern recognition. Finding the optimal combination of the hyper-parameters of such a l…
Reduction of Kinetic Equations to Liénard-Levinson-Smith Form: Counting Limit Cycles
Sandip Saha, Gautam Gangopadhyay, Deb Shankar Ray
We have presented an unified scheme to express a class of system of equations in two variables into a Liénard-Levinson-Smith (LLS) oscillator form. We have derived the condition fo…
When an oscillating center in an open system undergoes power law decay
Sandip Saha, Gautam Gangopadhyay
We have probed the condition of periodic oscillation in a class of two variable nonlinear dynamical open systems modeled with Lienard-Levinson-Smith(LLS) equation which can be a li…
