Solutions using the new equation set are shown to be grid-independent for the conditions considered and to have an intuitively correct sensitivity to friction, however small instabilities and increased errors on predicted depth were noted when Manning's n = 0.01.
Clustering the complete data set with different random starting positions leads to very small instabilities (<0.003) for the whole range from two to twelve clusters.
This occurs in the case of a low mode number perturbation with a very small amplitude, where the growth of secondary small-scale instabilities leads to substantial differences between the codes after re-shock.
electron density in the ionosphere; electronic density gradient; small-scale instabilities.
The reflection coefficient of whistler waves from the ionosphere is determined by several factors, which can be stimulated by acoustic-gravity waves: electron density in the ionosphere; electronic density gradient; small-scale instabilities.
Numerical examples demonstrate that the increase of the viscosity coefficient causes the lager instability threshold of speed fluctuation amplitude for given detuning parameter and smaller instability range of the detuning parameter for given speed fluctuation amplitude.
Especially, in remote sensing where delays are large, and in high-speed applications with even small delays, instability can be inevitable.
This paper proposes a robust optimal centralized controller to mitigate the small signal instability caused by the interaction between the control loops of rectifier interfaced active loads (RIALs) and the inverter interfaced distributed generations.
To determine a small pool instability index we determined the frequency of each CAG repeat length, and multiplied each frequency by the number of repeats (+ or -) from the modal CAG length.
Thus, there is a net duskward E y field associated with the earthward drift of the fronts that is modulated by the small-scale BICI instability.
