Continuous wavelet transform based time-scale and multi-fractal analysis of the nonlinear oscillations in a hollow cathode glow discharge plasma
Md. Nurujjaman, Ramesh Narayanan, A. N. Sekar Iyengar
Continuous wavelet transform (CWT) based time-scale and multi-fractal analyses have been carried out on the anode glow related nonlinear floating potential fluctuations in a hollow…
Stochastic behaviour in the edge region of the SINP tokamak
Ramesh Narayanan, Md. Nurujjaman, A. N. Sekar Iyengar
Stochasticity is one of the most extensively researched topics in laboratory and space plasmas since it has been successful in explaining the various anomalous processes like trans…
Comparative study of nonlinear properties of EEG signals of a normal person and an epileptic patient
Md. Nurujjaman, Ramesh Naryanan, A. N. Sekar Iyengar
Background: Investigation of the functioning of the brain in living systems has been a major effort amongst scientists and medical practitioners. Amongst the various disorder of th…
Fractal Dimensionof the El Salvador Earthquake (2001) time Series
Md. Nurujjaman, Ramesh Narayanan, A. N. Sekar Iyengar
We have estimated multifractal spectrum of the El Salvador earthquake signal recorded at different locations.
Parametric investigation of nonlinear fluctuations in a dc glow discharge plasma
Md. Nurujjaman, Ramesh Narayanan, A. N. Sekar Iyengar
Glow discharge plasmas exhibit various types of self excited oscillations for different initial conditions like discharge voltages and filling pressures. The behavior of such oscil…
