Most dynamic activities are closely related to the variation of accelerations in vertical direction.
Since the VGRF exerted on the foot affects variations of acceleration, velocity, position and mechanical energy of the body's center of mass vertically [21], while walking, the center of mass of the two groups shares almost the same kinetic and kinematic characteristics.
It is found that features related to the variations of accelerations and decelerations (e.g., the proportions of accelerations and decelerations larger than 1 meter per square second, and the standard deviations of accelerations and decelerations) are the most effective in terms of vehicle classification using GPS data.
A preliminary objective analysis of the system effectiveness was carried out by calculating the mean variation of longitudinal acceleration and throttle after a warning event.
This is the biggest group of elongation rates, providing the greatest statistical power, and 2. We only used elongation rates measured between these two timepoints for all genes to minimize the variation of intrinsic acceleration of Pol II in these genes.
With the aim of exploring the influence of wheelchair design variations on acceleration and velocity values for wheelchair rugby athletes, RMIT University research team has developed a purpose-built fully adjustable wheelchair frame for use with a wheelchair ergometer.
By using the dense array data, the variation of peak accelerations within a small area was examined.
Discontinuities in the curvature function, for example, may induce infinite variations of lateral acceleration, which of course, are not realizable.
Regardless of the changing device orientations, PCA may extract the walking direction along the maximum variations of the acceleration signals in the horizontal plane.
