—Large motion displacements in image sequences are still a problem for most motion estimation techniques. Progress in feature matching allows to establish robust correspondences between images for a sparse set of points. Recent works have attempted to use this sparse information to guide the dense motion field estimation. We propose to achieve this in an(More)
This prospective study measured and compared the diagnostic performance characteristics of various clinical signs and physical examination manoeuvres for carpal tunnel syndrome (CTS), including the scratch collapse test. Eighty-eight adult patients that were prescribed electrophysiological testing to diagnose CTS were enrolled in the study. Attending(More)
Automatic record and review of actions in sports training sessions is of great benefit to both coach and athlete. Many coaching sessions involve repetition of particular actions to hone technique, such as a swing from a tennis racket, golf club, or cricket bat. These actions can be defined by unique motion signatures. A method is proposed to parse the(More)

This paper shows how H ∞-design methods successfully can be used for control of jet engines in a multivariable framework. The work concludes experiences from both analysis and design studies concerning control of the Volvo Aero jet engine RM12, which is currently placed in the Swedish air fighter JAS39 Gripen. The emphasis is on useful methods for design(More)
