I thought of the great
precessional cycle that the pole of the earth describes.
It's been measured with radio experiments on previous landers (one
precessional cycle lasts about 166,000 years), but RISE's measurement will be more precise.
Today, STT is announcing a new breakthrough the company dubs
Precessional Spin Current.
where [??] = [f.sub.1] sec 2[[omega].sub.0] and in particular, setting [f.sub.2] = [f.sub.1] = 0, we end up with a
precessional motion with [alpha] = const., while [omega](t) and [[omega].sub.0](t) can still be determined from (84).
STIR relies on T1 relaxation differences instead of
precessional frequency differences to cancel the signal from fat, thereby minimising susceptibility effects during fat-suppressed imaging.
When fat and water molecules occupy the same voxel, differences in
precessional frequency quench MR signal in that voxel during opposed-phase gradient-echo MR imaging.

This value is in the range of the
precessional cycle of the Earth's orbit.
Under the macrospin model and assuming a uniform ellipsoidal particle with demagnetizing tensor axes [N.sub.x], [N.sub.y], and [N.sub.z] ([N.sub.x] + [N.sub.y] + [N.sub.z] = 4[pi]), Kittel [13] derived the frequency for the uniform
precessional mode, also known as ferromagnetic resonance mode as [[omega].sub.0] = [gamma][([[H.sub.z] + ([N.sub.y] - [N.sub.z])[M.sub.Z]] x [[H.sub.z] + ([N.sub.x] - [N.sub.z]) [M.sub.z]]).sup.1/2].

For perfectly spherical source the lense thrilling
precessional rates for the node and the perigee were obtained.
Let [[omega].sub.pcn] be the
precessional angular speed, and let [v.sub.pcn] be the linear speed.
