Internal and external harmonics in bi-cyclide coordinates

Dupin's cyclide and the cyclide patch

To retrieve models from a data base for recognizing objects in stereo, a new formulation of patches of Dupin's Cyclide provides a succinct representation of surface shape. The parameters can be extracted from the Weingarten Map and its derivatives at a point where a contour meets an extremal boundary.

Control Model for Dampening Hand Vibrations Using Information of Internal and External Coordinates

In the present study, we investigate a control mechanism that dampens hand vibrations. Here, we propose a control method with two components to suppress hand vibrations. The first is a passive suppression method that lowers the joint stiffness to passively dampen the hand vibrations. The second is an active suppression method that adjusts an equilibrium point based on skyhook control to activel...

External and Internal Relations ∗

In the index to Appearance and Reality (First Edition) Mr. Bradley declares that all relations are “intrinsical”; and the following are some of the phrases by means of which he tries to explain what he means by this assertion. “A relation must at both ends affect, and pass into, the being of its terms” (p. 364). “Every relation essentially penetrates the being of its terms, and is, in this sens...
