This is a tutorial review on systems theory and its applications to space plasma physics and, more broadly, on geophysics. With its basis on the state representation of a plasma the …
The schemes for the generation of surrogate data in order to test the null hypothesis of linear stochastic process undergoing nonlinear static transform are investigated as to their …

We report first results from a spatiotemporal statistical analysis of ionospheric emissions as observed by the Ultraviolet Imager (UVI) onboard the POLAR spacecraft during 4 months of …
J Argyris, I Andreadis, G Pavlos, M Athanasiou - Chaos, Solitons & Fractals, 1998 - Elsevier
The present paper investigates the influence of noise on the correlation dimension Dc of chaotic attractors arising in discrete and continuous in time dynamical systems. Our …
The deterministic chaotic behavior and dynamical complexity of the space plasma dynamical system over Nigeria are analyzed in this study and characterized. The study was …
KS Kumar, CVA Kumar, B George… - Journal of …, 2004 - Wiley Online Library
In this paper we report the evidence of a low‐dimensional chaos in a set of data observed outside laboratories. The dynamic behavior of the time series of the fluctuations of the total …
In this paper strong evidence is provided for significant far from equilibrium phase transition processes in the Earth's magnetosphere as revealed by the nonlinear analysis of in situ …
In this study we use Tsallis non-extensive statistics for a new understanding the magnetospheric dynamics and the magnetospheric self-organization during quiet and …

Geomagnetic activity is usually gauged by a single time‐dependent geomagnetic index. One drawback is that an individual geomagnetic index measures only one aspect of the …
