Wavelet Based Volatility Clustering Estimation of Foreign Exchange Rates
A. N. Sekar Iyengar
We have presented a novel technique of detecting intermittencies in a financial time series of the foreign exchange rate data of U.S.- Euro dollar(US/EUR) using a combination of bo…

Coherence resonance in an unijunction transistor relaxation oscillator
Md. Nurujjaman, P. S. Bhattacharya, A. N. Sekar Iyengar +1
The phenomenon of coherence resonance (CR) is investigated in an unijunction transistor relaxation oscillator (UJT-RO) and quantified by estimating the normal variance (NV). Depend…
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…
