In this paper we have analyzed the total solar irradiance signal obtained from Earth Radiation Budget Satellite. After denoising this signal using simple exponential smoothing we experimented with this filtered signal to study its nature. Fractal dimension analysis has been applied on it and the obtained value of fractal dimension demonstrates anti-persistent behaviour (short memory process) which...
In the present paper we have analyzed the daily Forbush decrease indices from January 1, 1967 to December 31, 2003. First filtering the time series by Simple Exponential Smoothing, we have applied Scargle Method of Periodogram on the processed time series in order to search for its time variation. Study exhibits periodicities around 174, 245, 261, 321, 452, 510, 571, 584, 662, 703, 735, 741, 767,...
