This paper considers the problems of robust stability and stabilization for uncertain continuous singular systems with state delay. The parametric uncertainty is assumed to be norm-bounded. The purpose of the robust stability problem is to give conditions such that the uncertain singular system is regular, impulse free and stable for all admissible(More)
Although China has surpassed the United States as the world's largest carbon dioxide emitter, in situ measurements of atmospheric CO 2 have been sparse in China. This paper analyzes hourly CO 2 and its correlation with CO at Miyun, a rural site near Beijing, over a period of 51 months (Dec 2004 through Feb 2009). The CO 2-CO correlation analysis evaluated(More)
