Simulation and Analysis of Passive Rolling Compensation of High Sea Salvage System
Method and device of a flexible interception and salvage system was introduced in this paper. In order to study the effect of wave motion on salvage operation, we proposed a passive wave compensation scheme that utilizes a combination of variable-pitch ...

The Interaction of Pre-programmed Eye Movements With the Vestibulo-Ocular Reflex
The Vestibulo-Ocular Reflex (VOR) works to stabilize gaze during unexpected head movements. However, even subjects who lack a VOR (e.g., vestibulopathic patients) can achieve gaze stability during planned head movements by using pre-programmed eye ...
