Recently, model-based visual-tracking techniques have been developed for measuring physiological motion in robot-assisted minimally invasive surgery. However, the tracking of living tissue surfaces in ...

About An R Package containing the Spherical Branch and Bound (SBB) algorithm for computing Fréchet means for the circle and the 2-sphere equipped with the arc length as metric. Moreover, a wrapper for ...

First, the Hall sensor array is determined by combining the spherical triangle theory and the physical structure of the spherical motor. Then, a rotor position identification method is proposed based ...

Can be proved. In spherical geometry, straight lines describe great circles, triangles have a bulging shape, and the sum of the three corners is more than 180 degrees.

THE author of this book, who is one of the naval instructors on H.M.S. Britannia, has brought together the most important rules which are used in the solution of spherical triangles, and, after ...

Description This cut and glued clear plastic model is one of several in which A. Harry Wheeler illustrated properties of polar spherical triangles. A sticker on it reads: PT. An inner polar triangle ...
