Comment on: Curling rock dynamics — The motion of a curling rock: inertial vs. noninertial reference frames
We examine the approach used and the results presented in a recent publication (Can. J. Phys. 76, 295 (1998)) in which (i) a noninertial reference frame is used to examine the motion of a curling rock, and (ii) the lateral motion of a curling rock is attributed to left–right asymmetry in the force acting on the rock. We point out the important differences between describing the motion in an ine...
متن کاملA Curling Shot Tracking Program
We present an algorithm for tracking the position of a curling stone from broadcast footage of curling events. Due to the constant panning of the camera in addition to perspective changes in the image, this introduces a need for image rectification and tracking of the camera view on the ice. We break the algorithm in four distinct components: rectification, frame tracking, stone tracking, and l...
متن کاملAction Selection for Hammer Shots in Curling
Curling is an adversarial two-player game with a continuous state and action space, and stochastic transitions. This paper focuses on one aspect of the full game, namely, finding the optimal “hammer shot”, which is the last action taken before a score is tallied. We survey existing methods for finding an optimal action in a continuous, lowdimensional space with stochastic outcomes, and adapt a ...
متن کاملPhotoinduced curling of organic molecular crystal nanowires.
Materials that transform light into mechanical motion are interesting from both fundamental and technological perspectives. Photomechanical materials usually consist of photoreactive molecules assembled in an ordered matrix, for example a liquid crystal polymer. The use of molecular crystals as photomechanical materials is challenging, since strain between reacted and unreacted crystal phases o...
