SIMULATION OF EARTH'S POLES DYNAMICS USING ASK-ANALYSIS

abstract 0991405010 issue 99 pp. 149 – 188 30.05.2014 ru 947
Based on local semantic information models, we have examined the dependence of the dynamics of the displacement of the pole positions of celestial objects. We have also developed and differentiated an analysis of ASK-pole modeling of dynamics within sixty-year cycles of reference points and substantiated reasons for the population inversion and singular states in the dynamics of the pole
