Sentence examples for high frequency instabilities from inspiring English sources
An explosion-generated-plasma is explored for low and high frequency instabilities by taking into account the drift of all the plasma species together with the dust particles which are charged.
No high frequency instability has been observed.
High power solid-state amplifiers usually suffer from self-heating, high frequency instability, unbalanced feeding effects and suchlike that should be carefully taken into account in a reliable and robust design.
High frequency instability (HFI) and low frequency instability (LFI) are found to occur in this system.
For the other studies, MSI was analysed as previously described (Thibodeau et al, 1998; Halling et al, 1999) and tumours with high frequency instability (MSI-H, ⩾30% of the loci demonstrating MSI) (Boland et al, 1998; Halling et al, 1999) were regarded as showing defective MMR, whereas the others were categorized as showing intact MMR.
As the higher frequency instabilities grow, they combine with the kinetic ballooning instability to form strong EM field turbulence and thus cause plasma transport and heating.
Thus, we suggest the observations can be explained in terms of the scenario that when the kinetic ballooning instability (Pi2 disturbance) grows to large amplitude and saturates around the substorm onset, the ion velocity distribution forms bump-on-tail velocity distribution which provides the free energy for exciting higher frequency instabilities such as the cross-tail current instability.
The present investigation is motivated by the problem of high-frequency instabilities in liquid rocket engines.
Improper screw designs can lead to high-frequency instabilities caused by melt temperature or pressure variations in the extruder.
Under impulsive input, the transient damped dynamics of this system exhibit transient resonance captures (TRCs) causing intentional large-amplitude and high-frequency instabilities in the response of the NES.
Both types of the instabilities are high-frequency instabilities but carry growth rates of different magnitudes.
