OBJECTIVES The purpose of this study was to establish reliability and responsiveness of the dynamic visual acuity test (DVAT) at head speeds of 150-200 degrees per second (deg/s) and the gaze stabilization test (GST) in high school and college football players. DESIGN Reliability design. PARTICIPANTS Fifty high school and college football athletes completed the DVAT and GST in both the yaw ...

The application of conventional wind turbines on board a vessel creates a number of new challenges for turbine control systems. Thrust force is used in marine applications as an additional control variable for propulsion of the vessel. Variability of the wind speed and wind direction, together with the yaw rate and range constraints, impose strong requirements on the turbine control system. A n...

Abstract. In wind plants, turbines can be yawed into the to steer their wakes away from downstream and achieve an overall increase in plant power. Mathematical optimization is typically used determine best yaw angles at which operate a plant. this paper, we present new heuristic rapidly method, define turbine as Boolean – either predefined angle or nonyawed opposed typical methods of defining c...

L. W. Schultheis and D. A. Robinson showed that the axis of the rotational vestibuloocular reflex (RVOR) cannot be altered by visual-vestibular mismatch ("cross-axis adaptation") when the vestibulocerebellum is lesioned. This suggests that the cerebellum may calibrate the axis of eye velocity of the RVOR under natural conditions. Thus we asked whether patients with cerebellar disease have alter...

A 3 degrees of freedom (surge, sway, and yaw) nonlinear controller for path following of marine craft using only two controls is derived using nonlinear control theory. Path following is achieved by a geometric assignment based on a line-of-sight projection algorithm for minimization of the cross-track error to the path. The desired speed along the path can be specified independently. The contr...

Building on the recent advances in the Fisher kernel framework for image classification, this paper proposes a novel image representation for head yaw estimation. Specifically, for each pixel of the image, a concise 9-dimensional local descriptor is computed consisting of the pixel coordinates, intensity, the first and second order derivatives, as well as the magnitude and orientation of the gr...

Previous research into the effects of viewpoint change on face recognition has typically dealt with rotations around the head's vertical axis (yaw). Another common, although less studied, source of viewpoint variation in faces is rotation around the head's horizontal pitch axis (pitch). In the current study we used both a sequential matching task and an old/new recognition task to examine the e...
