Abstract: A method, a system and an electronic device for processing audio-visual data. In the method, a first dataset is obtained, where the first dataset includes several data pairs, and each of the data pairs in the first dataset includes a video frame and an audio clip that match each other. A multi-channel feature extraction network model is established to extract the visual features of each video frame and the auditory features of each audio clip in the first dataset. A contrastive loss function model is established using the extracted visual features and the auditory features to train the multi-channel feature extraction network. A classifier is established to determine whether an input audio-visual data pair is matched.

Abstract: The present invention discloses a computed tomography (CT) system and a CT image reconstruction method. The method is implemented by an information processing system module, a display terminal module, an image reconstruction system module and a CT system module. The information processing system module is composed of an information receiving system module, an information sending system module and an information processing system module. During scanning, different nodes are arranged and quickly scanned to obtain data of a node, and then data of different nodes is synchronized, collected and summarized, so that a reconstruction unit can be analyzed, an objective function can be optimized, and data can be quickly analyzed and processed. In this way, the CT system and the CT image reconstruction method resolve the problems that an existing CT system and CT image reconstruction method have high requirements for projection data sets, and scanning requires a long time.

Abstract: The present invention discloses a motor-magnetostrictive actuator hybrid brake-by-wire system. The system includes a motor, a transmission mechanism, a magnetostrictive-driving piston mechanism and a floating-caliper disc mechanism. The transmission mechanism includes a planetary gear set and a screw set, and is driven by the motor. The linear motion of the sleeve is achieved by the planetary gear set and screw set. The sleeve pushes forward the piston head of the magnetostrictive-driving piston mechanism and the piston head pushes forward the brake pad back plate of the floating-caliper disc mechanism to clamp the brake disc, which accomplishes braking. The present invention uses the motor and the magnetostrictive-driving piston mechanism as a combined BBW system, which will simultaneously solve the problems of slow response, low precision and motor stalling effect of the only motor-driving braking systems and, also avoid the drawback of insufficient mechanical capabilities of the only magnetostrictive actuator-driving braking systems.
