Spatiotemporal fragmentation as a mechanism for different dynamical modes of behaviour in the solar convection zone
Eurico Covas, Reza Tavakol, David Moss
Recent analyses of the helioseismic observations indicate that the previously observed surface torsional oscillations with periods of about 11 years extend significantly downwards…

Torsional oscillations in the solar convection zone
Eurico Covas, Reza Tavakol, David Moss +1
Recent analysis of the helioseismic observations indicate that the previously observed surface torsional oscillations extend significantly downwards into the solar convection zone.…

Absence of supersensitivity to small input signals in generalized on--off systems
Eurico Covas, Reza Tavakol
It has recently been shown that nonlinear skew product dynamical systems with invariant subspaces which are capable of displaying on-off intermittency can show supersensitivity to…
