60 GHz Blockage Study Using Phased Arrays
, 2017 The millimeter wave (mmWave) frequencies offer the potential for enormous capacity wireless links. However, designing robust communication systems at these frequencies requires that we understand the channel dynamics over both time and space: mmWave ...

Time-Optimal Path Tracking via Reachability Analysis [PDF]
2018 IEEE International Conference on Robotics and Automation (ICRA), 2018 Given a geometric path, the Time-Optimal Path Tracking problem consists in finding the control strategy to traverse the path time-optimally while regulating tracking errors. A simple yet effective approach to this problem is to decompose the controller into two components: (i)~a path controller, which modulates the parameterization of the desired path ...

Shortest path refinement For HARP motion tracking [PDF]
SPIE Proceedings, 2009 Harmonic phase (HARP) motion analysis is widely used in the analysis of tagged magnetic resonance images of the heart. HARP motion tracking can yield gross errors, however, when there is a large amount of motion between successive time frames. Methods that use spatial continuity of motion-so-called refinement methods-have previously been reported to ...

Multibeam optical apparatus and method for tracking control for an optical disk having a set of tracks [PDF]
, 1996 A multitrack optical disk has two or more circular or spiral tracks, which are recorded or played back in simultaneous sets for high data rates. Tracking is accomplished by sets of first and second tracking pads, which lie partially on and partially off ...
