Abstract: With the increase in train speed, the aerodynamics in tunnels is emerging. In recent years, we have carried out a few full-scale tests about tunnel aerodynamics, and the law of influence of train speed on pressure change, ...

Abstract: This study aims to use an improved rotational region convolutional neural network (R2CNN) algorithm to detect the grasping bounding box for the robotic arm that reaches supermarket goods. This algorithm can calculate the ...

Abstract: Subgrade failure is relative to spectrum signal received by ground penetrating radar. For the practical exploring demand of Beijing road surface, the method to identify hidden diseases in subgrade such as cavity and loose ...
