Reconstruction of Lowdimensional Magnetospheric Dynamics by Singular Spectrum Analysis
نویسندگان
چکیده
The low dimensionality of magnetospheric activity indicated by previous phase space reconstructions using the AE and AL data suffer from the limitations of these t chniques. In this paper the singular spectrum analysis is used to study the global magnetospheric dynamics using the AE data and it yields a correlation dimension m2.5, thus confirming the low dimensionality published earlier. Further, this technique shows that the global magnetospheric dynamics can be described by 3 variables whose dynamical features are obtained from the AE data.

SVD analysis of the magnetospheric AE index time series and comparison with low-dimensional chaotic dynamics
The singular value decomposition (SVD) analysis is used at different stages in this paper in order to extract useful information concerning the underlying dynamics of the magnetospheric AE index. As a frame of reference we use the dynamics of the Lorenz system perturbed by external noise, white or colored. One of the critical results is that the colored noise can be differentiated from the whit...
متن کاملPredicting the Brexit outcome using singular spectrum analysis
In a referendum conducted in the United Kingdom (UK) on June 23, 2016, $51.6\%$ of the participants voted to leave the European Union (EU). The outcome of this referendum had major policy and financial impact for both UK and EU, and was seen as a surprise because the predictions consistently indicate that the ``Remain'''' would get a majority. In this paper, we investigate whether the outcome o...
متن کاملStability Analysis and Robust PID Control of Cable Driven Robots Considering Elasticity in Cables
In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...
متن کاملThe Chaotic or Non-chaotic Behavior of Global Geomagnetic Processes
Numerous linear studies of the geomagnetic indices have shown that the magnetospheric system is neither periodic nor quasiperiodic, and that only part of the AE variation can be explained as a direct linear response to the solar wind. This suggests the possibility that the magnetosphere is a non-linear system, and recent studies have been directed to determining whether the magnetospheric syste...
متن کاملState Space Reconstruction: Method of Delays vs Singular Spectrum Approach
The analysis of chaotic time series requires proper reconstruction of the state space from the available data in order to successfully estimate invariant properties of the embedded attractor. Using the correlation dimension, we discuss the applicability of the two most common methods of reconstruction, the method of delays (MOD) and the Singular Spectrum Approach (SSA). Contrary to previous dis...
