Ball Throwing on Spheres
Ball throwing on Euclidean spaces has been considered for a while. A suitable renormalization leads to a fractional Brownian motion as limit object. In this paper we investigate ball throwing on spheres. A different behavior is exhibited: we still get a Gaussian limit but which is no longer a fractional Brownian motion. However the limit is locally self-similar when the self-similarity index H ...
متن کاملKinectBalls: An Interactive Tool for Ball Throwing Games
We present a tool that was developed in the context of the first author’s masters project. The tool implements an interactive computer game combining the real and the virtual world in a seamless way. The player interacts with the game by throwing balls towards a wall on which a virtual 3D scene is projected. Using the Kinect 3D sensor, we compute and predict the trajectory, speed and position o...
متن کاملUtilization and compensation of interaction torques during ball-throwing movements.
The manner in which the CNS deals with interaction torques at each joint in ball throwing was investigated by instructing subjects to throw a ball at three different speeds, using two (elbow and wrist) or three joints (shoulder, elbow, and wrist). The results indicated that the role of the muscle torque at the most proximal joint was to accelerate the most proximal joint and to produce the effe...
متن کاملHighly Accurate Tennis Ball Throwing Machine with Intelligent Control
The paper presents an advanced control system for tennis ball throwing machines to improve their accuracy according to the ball impact points. A further advantage of the system is the much easier calibration process involving the intelligent solution of the automatic adjustment of the stroking parameters according to the ball elasticity, the self-calibration, the use of the safety margin at ver...
متن کاملMEAN VALUE INTERPOLATION ON SPHERES
In this paper we consider multivariate Lagrange mean-value interpolation problem, where interpolation parameters are integrals over spheres. We have concentric spheres. Indeed, we consider the problem in three variables when it is not correct.
