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 WebbLong-time coherent integration works to significantly increase the detection probability for maneuvering targets. However, during the observation time, the problems that often tend to occur are range cell migration (RCM) and Doppler frequency cell migration (DFCM), due to the high velocity and acceleration of the maneuvering target, which can reduce the …

Nystagmus slow-phase velocity during vestibular

Webb30 sep. 2014 · mean slow-phase velocity One of the crucial clinical signs for differentiation between acute peripheral and central vertigo is whether the spontaneous nystagmus can be suppressed by visual fixation (see reference 1 ). WebbIn Rhesus monkeys the slow-phase velocity of nystagmus was measured during optokinetic, vestibular, and combined stimulation.

WebbHowever, the slow phase velocity envelope during per- or post-rotatory nystagmus is more accurately represented by two exponential modes. One represents activity in the vestibular nerve induced by deflection of the cupula, the other by activation that the input from the canals produces in the central velocity storage integrator. canon ir-adv c256if driver
