We demonstrate a method to achieve an extremely wide and flexible external control of the group velocity of signals as they propagate along an optical fibre. This control is achieved by means of the gain and loss mechanisms of stimulated Brillouin scatteri ...
High speed rotation of small rotors is needed more and more in many industrial applications. Classical examples are compact devices like scanners, gyroscopes, centrifuge units and so on. The key to achieve high rotating speeds is to have contactless bearin ...
This paper aims to propose a novel approach to generate new generic human walking patterns using motion-captured data, leading to a real-time engine intended for virtual humans animation. The method applies the PCA (principal component analysis) technique ...
Purpose: To explore whether triaxial accelerometric measurements can be utilized to accurately assess speed and incline of running in free-living conditions. Methods: Body accelerations during running were recorded at the lower back and at the heel by a po ...
The invention relates to an interferometer system (41), especially for use in a co-ordinate measuring system. Said interferometer system comprises, disposed in an illumination beam path, a pair of spaced-apart boundary surfaces (52, 53). A boundary surface ...
A new system, Physilog, for ambulatory monitoring of movement is proposed and its applications in orthopaedic, physiology, angiology and quality of life are presented. Body accelerations were recorded by a portable measuring device. Significant parameters ...
The simulation of mobility models such as the random waypoint often cause subtle problems, for example the decay of average speed as the simulation progresses, a difference between the long term distribution of nodes and the initial one, and sometimes the ...
We describe the muscle synergies accompanying steering of walking along curved trajectories, in order to analyze the simultaneous control of progression and balance-threatening emerging forces. For this purpose, we bilaterally recorded in ten subjects the ...
During the dry season of the year 2002, convective cooling triggered the formation of a double-diffusive regime of the convective type below the chemocline at 52m depth in Lake Nyos. Since then, the vertical extent of the double-diffusive staircase has con ...
A method to achieve an extremely wide and flexible control of the group velocity in an optical fiber using stimulated Brillouin scattering is presented. Group velocities below 71,000 km/s on one hand, well exceeding the speed of light in vacuum on the othe ...
