Direct measurement of diurnal polar motion by ring laser gyroscopes
[1] We report the first direct measurements of the very small effect of forced diurnal polar motion, successfully observed on three of our large ring lasers, which now measure the instantaneous direction of Earth’s rotation axis to a precision of 1 part in 10 when averaged over a time interval of several hours. Ring laser gyroscopes provide a new viable technique for directly and continuously m...
متن کاملThe Accuracy of Surface Measurement for Osteoporotic Spine Motion Analysis
INTRODUCTION The surface method of measuring lower thoracic and lumbar spine motion with Fastrak ® was examined for validity. There is an increasing awareness of the health risks of exposure to radiation associated with repeated radiographic assessment of spinal curvature and spinal movements. As a skin-surface measurement device, Fastrak ® was employed to study the effect of low bone mineral d...
متن کاملVisual Tracking using Kernel Projected Measurement and Log-Polar Transformation
Visual Servoing is generally contained of control and feature tracking. Study of previous methods shows that no attempt has been made to optimize these two parts together. In kernel based visual servoing method, the main objective is to combine and optimize these two parts together and to make an entire control loop. This main target is accomplished by using Lyapanov theory. A Lyapanov candidat...
متن کاملBrownian Motion with Polar Drift
Consider a strong Markov process X° that has continuous sample paths in Rd (d > 2) and the following two properties. (1) Away from the origin X° behaves like Brownian motion with a polar drift given in spherical polar coordinates by n{8)/2r. Here /i is a bounded Borel measurable function on the unit sphere in RJ, with average value Ji. (2) X° is absorbed at the origin. It is shown that X° reach...
