in this paper, the combined effect of suspended (fine dust) particles and rotation on the onset of thermosolutal convection in an elastico-viscous fluid in a porous medium is studied. for the porous medium, the brinkman model is employed and rivlin-ericksen model is used to characterize viscoelastic fluid. by applying normal mode analysis method, the dispersion relation has been derived and sol...
Spontaneous toroidal rotation of impurity ions has been observed in the core of Alcator C-Mod plasmas with no external momentum input. The magnitude of the rotation ranges from −60 km/s (counter-current) in limiter L-mode discharges to +140 km/s (co-current) in ICRF heated H-mode plasmas. The core rotation in L-mode plasmas is generally counter-current and is found to depend strongly on the mag...
Modulation is the technique in which carrier signal varies according to amplitude of modulating signal. A brilliant solution for realizing digital modulators is CORDIC (CO-ordinate Rotation Digital Computer) algorithm. Rotation mode and vector mode are two modes in which this algorithm is used. Here rotation mode is used to convert the coordinates from polar mode to rectangular mode. This paper...
We have made two significant discoveries in our recent studies of quiescent H-mode (QH-mode) plasmas in DIII-D. First, we have found that we can control the edge pedestal density and pressure by altering the edge particle transport through changes in the edge toroidal rotation. This allows us to adjust the edge operating point to be close to, but below the ELM stability boundary, maintaining th...
A new mathematical formalism, based on a coupled-mode approach, is presented to describe light propagation in birefringent optically active crystals. An arbitrary light wave in the medium is represented as an expansion in terms of linearly polarized eigenmodes; explicit solutions of the equations for the coupled-wave amplitudes show how power is transferred between the principal components in t...
We provide a new analysis technique to measure the effect of isotropic polarization rotation, induced by e.g. cosmic birefringence from axion-like particles and miscalibration CMB angle, via mode coupling in microwave background (CMB). Several secondary effects such as gravitational lensing optical-depth anisotropies lead observed anisotropies, i.e., non-zero off-diagonal elements covariance. T...
We present the results of numerical time evolutions of the linearised perturbations of rapidly and rigidly rotating Newtonian polytropes while making the Cowling approximation. The evolution code runs stably for hundreds of stellar rotations, allowing us to compare our results with previously published eigenmode calculations, for instance the f-mode calculations of Ipser & Lindblom, and the r-m...
