The oscillation overthruster was created by Riva and visual effects supervisor Michael Fink out of a gyroscope to which a metal frame, wires, circuits, and tiny strobe lights were added. [ 9 ] Cinematographer Jordan Cronenweth was initially hired as the film's director of photography but, halfway through production, producers replaced him with ...
Also, there was an episode of Enterprise that featured Peter Weller, the guy who plays Banzai, and there is a scene where he very prominently uses a prop that is a exact duplicate of the oscillation overthruster prop. 147.31.8.101 03:05, 25 February 2009 (UTC)
This happens because the phase noise does not affect the total power in the signal, it only affects its distribution. Without noise, S v (f) is a series of impulse functions at the harmonics of the oscillation frequency. With noise, the impulse functions spread, becoming fatter and shorter but retaining the same total power.
Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sensation evoked by the oscillation described in (a)."
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current .
The MSW effect is broadly analogous to the differential retardation of sound waves in density-variable media, however it also involves the propagation dynamics of three separate quantum fields which experience distortion. In free space, the separate rates of neutrino eigenstates lead to standard neutrino flavor oscillation.
In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
