Rotation control of a parametrically excited pendulum by adjusting its length
(Pergamon-Elsevier Science Ltd, 2016-03)
We present a new control strategy for the vertically excited parametric pendulum, with a view on energy harvesting from rotating motion. Two possible energy sources are considered: a vibrating machine, represented by a ...
Rotation effect on geodesic and zonal flow modes in tokamak plasmas with isothermal magnetic surfaces
(IOP PUBLISHING LTD, 2011)
The electrostatic geodesic mode oscillations are investigated in rotating large aspect ratio tokamak plasmas with circular isothermal magnetic surfaces. The analysis is carried out within the magnetohydrodynamic model ...
Tidal friction in close-in satellites and exoplanets: The Darwin theory re-visited
(SPRINGER, 2008)
This report is a review of Darwin`s classical theory of bodily tides in which we present the analytical expressions for the orbital and rotational evolution of the bodies and for the energy dissipation rates due to their ...
Creep tide model for the three-body problem: The rotational evolution of a circumbinary planet
(EDP Sciences, 2021-07)
We present a tidal model for treating the rotational evolution in the general three-body problem with arbitrary viscosities, in which all the masses are considered to be extended and all the tidal interactions between pairs ...
Extended spherical collapse and the accelerating universe
(Singapura, 2014-04-10)
The influence of the shear stress and angular momentum on the nonlinear spherical
collapse model is discussed in the framework of the Einstein–de Sitter and ΛCDM models.
By assuming that the vacuum component is not ...
No Evidence for Internal Rotation in the Remnant Core of the Sagittarius Dwarf
(2011)
We have conducted a spectroscopic survey of the inner regions of the Sagittarius (Sgr) dwarf galaxy using the AAOmega spectrograph on the Anglo-Australian Telescope. We determine radial velocities for over 1800 Sgr star ...
