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.

All tissues cause the X rays to slow down, resulting in what's known as a phase shift. The size of the shift depends on the type of tissue.
where [[alpha].sup.corr.sub.n] = k[DELTA][z.sup.broad.sub.n] are the terms that have the function of correcting the surface deformation and coincide with the phase shifts required by the PM to retrieve the pattern of the broadside array (they are given by the product between the wave vector k and [DELTA][d.sub.n] in Figure 3), while [mathematical expression not reproducible] is simply the phase shift that must be introduced into the nth element of the undeformed planar array in order to steer its main lobe into the desired direction.

Based on this observation, Weir Minerals Netherlands recommended installing a phase shift controller, which controls the phase shift between the crankshafts of the individual pumps, minimizing the effect of the hydraulic resonances.
Typical phase shift error ranges from +/- 0.9 to +/- 5 degrees over 8 binary increments with fast switching speed performance from 30 to 450 nsec.
This was the calibration (and determination oh the phase shift) of the model.
