This study aims at using electrooculographic (EOG) features, mainly slow eye movements (SEM), to estimate the human vigilance changes during a monotonous task. In particular, SEMs are first automatically detected by a method based on discrete wavelet transform, then linear dynamic system is used to find the trajectory of vigilance changes according to the SEM proportion. The performance of this system...
The ultra high voltage direct current(UHVDC) is the important technical means for the solution of high voltage, large capacity, and long distance power transmission. plusmn 800 KV UHVDC transmission technology will be used in the projects which transfer hydroelectric power in Yunnan Province and Jingshajiang river to Guangdong Province and Shanghai and other places in China. Along with the rapid development...
