phase shift

in nuclear magnetic resonance, the change in phase caused by movement of the spins, which can be used to show fluid flow.

phase shift

An alteration in the time relationship between the peaks (or troughs) of two different periodic functions. Thus, two circadian rhythms may suffer a phase shift as in jet lag.

L] > 0 then [empty set]" > 0 thus the differential phase shift is a convex function because it is a twice differentiable function and its second derivative is positive.
The maximum phase shift range that can be obtained when the oscillator is injection-locked at the fundamental harmonic component of the autonomous signal is limited to 180[degrees] [8-10].
The phase shift of the design is tuned by the terminating impedances.
The transmission coefficient, t, is related to the GoosHanchen phase shift, [PHI], [12,18] as:
Scientists have speculated on many possible causes of phase shift, but this study is the first one to clearly show that a rapid change in the dominant life forms on a coral reef is associated with man-made structures.
In order to sustain oscillation, the loop must meet two criteria -- the loop gain must be equal to unity, and the phase shift at the desired frequency of oscillation must be equal to an integer multiple (n) of 360[degrees].
It is important to note here that only the phase shift a1 can be evaluated by comparing the signals of [I.
All tissues cause the X rays to slow down, resulting in what's known as a phase shift.
He finds that the amplitude of the line soliton converges to that of the line soliton at initial time, whereas jumps of the local phase shift of the crest propagate in a finite speed toward y equals more or less infinity.
This paper deals with a modeling of the phase shift keying (PSK) modulation technique and its multi-level variations, which appears to be very resistant to nonlinear effects present in the optical transmission medium [4, 5].
Vehicles traveling at hypersonic speed experience degradation of radio communications including telemetry and GPS navigation, because of effects from plasma sheath caused by the free electrons in the gas, including signal attenuation, phase shift, noise, etc.
