Slow phases longer than 200 ms were divided … WebbThe velocity profile of slow phases may be linear or exponentially decreasing or increasing. Acquired jerk nystagmus typically has linear or decreasing velocity slow phases, with linear forms arising from asymmetric vestibular tone and decreasing velocity forms arising from dysfunction of gaze-holding neural integration networks.
WebbIn this study, gain of slow-phase velocity in OKN response to stimulation velocity was analyzed by two methods of stimulation, constant acceleration, and constant velocity … The phase velocity of a wave is the rate at which the wave propagates in any medium. This is the velocity at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave (for example, the crest) will appear to travel at the phase velocity. The phase velocity is … Visa mer The group velocity of a collection of waves is defined as $${\displaystyle v_{g}={\frac {\partial \omega }{\partial k}}.}$$ When multiple sinusoidal waves are propagating … Visa mer • Cherenkov radiation • Dispersion (optics) • Group velocity • Propagation delay • Shear wave splitting Visa mer In the context of electromagnetics and optics, the frequency is some function ω(k) of the wave number, so in general, the phase velocity and the group velocity depend on specific medium and frequency. The ratio between the speed of light c and the phase … Visa mer
