Detecting vehicles in aerial images provides important information for traffic management and urban planning. the cars is challenging due to relatively small size of target objects complex background man-made areas. It particularly if goal near-real-time detection, i.e., within few seconds, on large without any additional information, e.g., road database accurate size. We present a method that can detect 21-MPixel original frame image scale seconds laptop single threaded. In addition...

The behaviors between FRP and concrete are simulated with shear friction model. Comparisons predictions from test results demonstrate accuracy FE...
Specialized pest control for agriculture is a high-priority agricultural issue. There are multiple categories of tiny pests, which pose significant challenges to monitoring.
