15 صفحه اولDetecting Irregularities in Cyclic Motion
Real cyclic motions tend not to be perfectly even, i.e., the period varies slightly from one cycle to the next, because of physically important changes in the scene. A generalization of period is de ned for cyclic motions that makes periodic variation explicit. This representation, called the period trace, is compact and purely temporal, describing the evolution of an object or scene without re...
متن کاملPredictability of the Earth's Polar Motion
The numerical prediction of the Earth's polar motion is of both theoretical and practical interests. The present paper is aimed at a comprehensive, experimental study of the predictability of the polar motion using a homogeneous BIH (Bureau International de FHeure) data set for the period 1967-1983. Based on our knowledge of the physics of the annual and the Chandler wobbles, we build the numer...
متن کاملCoseismic Excitation of the Earth’s Polar Motion
Apart from the “shaking” near the epicenter that is the earthquake, a seismic event creates a permanent field of dislocation in the entire Earth. This redistribution of mass changes (slightly) the Earth’s inertia tensor; and the Earth’s rotation will change in accordance with the conservation of angular momentum. Similar to this seismic excitation of Earth rotation variations, the same mass red...
متن کاملVariable Thermal Conductivity and Thermal Radiation Effect on the Motion of a Micro Polar Fluid over an Upper Surface
The intent of this analysis is to explore the influence of thermal radiation paired with variable thermal conductivity on MHD micropolar fluid flow over an upper surface. The novelty of the present model is to consider the fluid flow along an upper horizontal surface of a paraboloid of revolution (uhspr) with the porous medium. This physical phenomenon is described by a set of coupled...
