In this paper, robot tracking of a moving target in cluttered environments by using an improved potential field controller is proposed. Genetic algorithms are used to improve the potential field controller by optimizing the forces applied to the robot. This improvement makes the robot path much more smoother during the tracking. A measure of smoothness is(More)
OBJECTIVE To correlate corneal endothelium-Descemet membrane (EDM) layer parameters of scroll tightness with donor age, endothelial cell density (ECD), and history of diabetes. METHODS Endothelium-Descemet membrane layer scrolls were harvested from 26 corneoscleral buttons using the SCUBA technique by a cornea-fellowship trained ophthalmologist masked to(More)
