The movement and response characteristics of bit during percussion process, [tau], and transfer rate of energy caused by percussion, an efficiency, depend on [m.sub.r] and [beta], where increase in [m.sub.r] leads to overdamping of bit movement characteristics due to [tau] by piston and reduction in drilling efficiency due to internal energy effect by mass of drill bit.
Therefore, when c > [c.sub.c], it represents the overdamping coefficient, and when c < [c.sub.c], it is the underdamping coefficient.
The continuous black solid line was the response of overdamping system, and it had no overshoot and a stable value at the end.
And the effects of the different damping coefficients including the underdamping coefficients and overdamping coefficients on the SNR are investigated.
Patient-ventilator synchrony was higher with the facemask than with the helmet as the helmet's large inner volume and compliance caused overdamping of the inspiratory pressure rise.
Results have shown, that "overdamping" fault resistance ranges between 20 [OMEGA] and 50 [OMEGA].
The critical radius where the bubble behavior changes from damping oscillation to overdamping one is obtained from the condition f = 0:
A number of factors are thought to contribute to suboptimal damping; air bubbles within the tubing system dramatically increase the CoD, as do blood clots--both resulting in overdamping, while excessive lengths of tubing reduce the CoD, resulting in underdamping.
On the contrary, A signal with low Q-factor is considered as overdamping. There are no oscillations in overdamping signals.
