The problem for the stability of train network control systems on electric multiple unit (EMU) with network-induced delay and packet dropout has been investigated. An equivalent continuous-time model is proposed to account for the train network control systems. Based on the obtained train network control systems model, employing Lyapunov theory together with some novel analysis techniques, less conservative...
Now more and more application demand to spatio-temporal database is proposed and the spatio-temporal data model is the fundamental basic to spatial-temporal database. But till today the study on spatio-temporal data model still more concerned with the theory research. The article proposes a new model-the change-of-feature based spatio-temporal object relational data model by researching and analyzing...
