Abstract For the purpose of object detection, numerous key points based methods have been suggested. To alleviate the imbalance problem that some objects may be missing when a single-center-point based network is used for object detection, we propose

Abstract Many residual network-based methods have been proposed to perform object detection. However, most of them may lead to overfitting or cannot perform well in small object detection and alleviate the problem of overfitting. We propose a multipl

Due to the friction-induced discontinuity of the clutch torque and ICE on/off, seamless mode transition of hybrid electric vehicles (HEVs) is difficult to achieve, which has a bad influence on the vehicle ride comfort. In the face of system uncontinu
