China is heavily suffered from various types of natural disasters, such as earthquakes and typhoons. This paper presents the monitoring and recognizing of seismic responses of a tied arch bridge, which has been installed with a long-term structural health monitoring system since November 2007 in Hangzhou, China. Wenchuan earthquake (Magnitude 8.0) occurred at 14∶28 (China standard time) on May 12,...
The development of software for Electric Load Management Center (ELMC) is presented in this paper. Based on the embedded real-time operating system VxWorks, ELMC performs multiple tasks including periodic and aperiodic ones. While rate monotonic (RM) algorithm is still used to process periodic tasks, we propose a condition triggered algorithm (CTA) to schedule aperiodic tasks by using VxWorks's semaphore...
Detecting vehicles from video sequence is very challenging due to the wide varieties of vehicle appearances and the complexity of the backgrounds. At present, many algorithms in the image recognition have a narrow applicability and a weak real-time. Aiming at this problem, a recognition method which was combined by features extraction using Gabor wavelet and BP neural network algorithm for the classification...
