Polar Motion and Signal Processing

1986
The source(s) of the polar motion are still a contoversial topic so that many techniques of signal processing have been applied but with elusive results. After recall of the basic equation of motion and its solution, the most usual methods are surveyed with emphasis on the frequently implicit hypotheses.

Polar motion and Earth rotation

Reviews of Geophysics, 1983
During the period from 1979 through 1982, polar motion and earth rotation activity centered on the development of new observation techniques and the investigations of the relation between the observed motions and geophysical phenomena. Determinations of polar motion through classical techniques continued, but the number of United States observing sites

Deformation induced by polar motion

Journal of Geophysical Research: Solid Earth, 1985
Variations in the geocentric position of the earth's rotation axis (polar motion) cause deformation within the earth. We estimate the effects of this deformation on radial and horizontal positions of points on the earth's surface, on baseline lengths between those points, and on surface gravity. The effects of the oceans and of the earth's anelasticity

Polarization, conformal invariants, and Brownian motion

1998
For a set \(A\) in the complex plane, let \(A_+=A\cap \{z:\text{Im} z\geq 0\}\), let \(A_-=A\cap \{z:\text{Im} z\leq 0\}\), and let \(\overline A=\{\overline z:z\in A\}\). If \(A\) is either an open set or a closed set, define the polarization of \(A\) by \(P(A)= (A\cup \overline A)\cup (A \cap \overline A)\).
