Polar Motion Ultra-Short-Term Prediction of Least-Squares+Multivariate Autoregressive Hybrid Method by Using the Kalman Filter [PDF]
SensorsThe polar motion (PM, including two parameters PMx and PMy) ultra-short-term prediction (1–10 days) is demanded in the real-time navigation of satellites and spacecrafts.

Kimura’s contributions on Earth polar motion studies [PDF]
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesKimura’s discovery of z-term in the polar motion (Astron. J. 22, 107 (1902) and Astron. Nachr. 158, 233 (1902)) was recognized as an epoch-making scientific achievement for modern Japan, opening its doors to the world in 1868.

Electroencephalography Enables Continuous Decoding of Hand Motion Angles in Polar Coordinates [PDF]
Cyborg and Bionic SystemsHand movements in task space are typically represented using either Cartesian or polar coordinate systems. While Cartesian coordinates are commonly used in electroencephalography (EEG)-based brain–computer interface (BCI) studies, polar coordinates offer

Climate‐driven polar motion [PDF]
Journal of Geophysical Research: Solid Earth, 1999 The output of a coupled climate system model provides a synthetic climate record with temporal and spatial coverage not attainable with observational data, allowing evaluation of climatic excitation of polar motion on timescales of months to decades. Analysis of the geodetically inferred Chandler excitation power shows that it has fluctuated by up to ...

Short periodic variations of polar motion and hemispheric atmospheric angular momentum excitation functions in the period 1984-1992 [PDF]
Annales Geophysicae, 1995 Short periodic oscillations with the periods from 10 up to 110 days of the hemispheric components of effective atmospheric angular momentum (EAAM) excitation function and their correlation with polar motion excitation function have been analyzed.

Brownian Motion With Polar Drift [PDF]
Transactions of the American Mathematical Society, 1985 Consider a strong Markov process X 0 {X^0} that has continuous sample paths in R d ( d ⩾ 2 ) {R^d}(d \geqslant 2) and the following two properties. (1) Away from the origin
