Markerless tracking of tennis racket motion using a camera
This research is concerned with tracking tennis racket movements. Previously, stereo camera systems have been used to track markers attached to rackets, which allows for racket movements to be obtained in three-dimensions. Typically, markers are manually selected on the image plane but this can be time consuming and inaccurate. This paper discusses a markerless method to measure three-dimension...

متن کاملProgress in ARDS research: a protection racket?
The acute respiratory distress syndrome in adults (ARDS) may complicate a wide variety of serious medical and surgical conditions, not all of which involve the lung directly. The pathogenesis remains unclear, but involves neutrophil recruitment to the alveoli and inflammatory pathway activation leading to increased permeability of the alveolarcapillary membrane and disordered vascular control, ...
متن کاملImpact of a ball with a bat or racket
The collision of a ball with a baseball bat or a tennis racket is usually modeled in terms of rigid body dynamics, assuming that the hand exerts no impulsive reaction force on the handle during the collision. In this paper, a uniform aluminum beam was used as an idealized bat or racket, in order to examine both the rigid body approximation and the assumption that the hand force can be neglected...
