statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...
Finger-jaw coordination during a deictic gesture with CVCV utterances: the effect of stress position
The present study investigates the hypothesis of a synchronization between the extremum (apex) of the pointing gesture and the apex of the jaw opening gesture for the stress vowel in 'CVCV vs CV'CV utterances in a deictic task (consisting in showing a target while naming it). The results show that for 'CVCV sequences (e.g. /pápa/) the pointing apex tends to be phased with the jaw apex for the f...
Mit der vorliegenden Arbeit wird eine Verbesserung des MAGIC (Manual And Gaze Input Cascaded) Pointing vorgestellt. Die Idee hinter dem MAGIC-Pointing ist die Positionierung des Mauszeigers auf die Blickposition auf dem Bildschirm bei der ersten Bewegung der Maus nach einer Ruhephase. Die Problematik beim MAGIC-Pointing liegt darin, dass die initiierte Mausbewegung dazu führt über das Ziel hina...
Stick balancing at the fingertip is a powerful paradigm for the study of the control of human balance. Here we show that the mean stick balancing time is increased by about two-fold when a subject stands on a vibrating platform that produces vertical vibrations at the fingertip (0.001 m, 15-50 Hz). High speed motion capture measurements in three dimensions demonstrate that vibration does not sh...
