Dexterous object manipulation requires suitable control of grip force, load force and digit positions. To keep an object stable in the air, force magnitude, force direction and digit positions should be coordinated, producing compensatory torque that could balance the external torque and maintain a minimal object roll. Six males and 6 females enrolled in the study. In the experiment, subjects were...
The purpose of this study was to explore the relationship between grip strength and inter-muscular coordination of the forearms and hands. Twenty-four healthy young volunteers participated in the experiment. The subjects were instructed to grip hydraulic hand dynamometer with five force levels-maximal voluntary contraction (MVC), 70% MVC, 50% MVC, 30% MVC and without any contraction. Muscle activity...
The weaknesses of GPS (Global Positioning System) is vulnerable to be jammed, so the study of jamming and anti-jamming of GPS has drawn more and more attention. In this paper, it analyzes the performance of GPS jamming and the anti-jamming of GPS receiver about blanket jamming. In addition, it establishes the simulation model based on MATLAB and gives the analysis of the performance of the anti-jamming...
