Abstract: This application describes a medical image classification method, a model training method, and a server. The medical image classification method includes: obtaining, by a device, a medical image data set. The device includes a memory storing instructions and a processor in communication with the memory. The method includes performing, by the device, quality analysis on the medical image data set, to extract feature information of a medical image in the medical image data set; and classifying, by the device, the medical image data set based on the feature information and by using a pre-trained deep learning network for performing anomaly detection and classification, to obtain a classification result.

Abstract: A reasonable millisecond time control method for excavation blasting of a tunnel is provided, and includes: acquiring physical mechanical parameters to establish a millisecond blasting model, and designing four dimensions blasting parameters of explosive quantity, hole number, inter-hole millisecond and inter-row millisecond; simulating, based on the millisecond blasting model, a blasting process of an explosive package using blasting parameters to obtain a blasting vibration curve; obtaining single-hole blasting vibration waveforms, solving a vibration synthesis curve through a vibration synthesis theory; comparing the vibration synthesis curve with the blasting vibration curve to obtain a coupling relationship of blasting parameters; determining a target group of explosive quantity and hole numbers, determining a target millisecond through the coupling relationship of blasting parameters, and relating a millisecond blasting control strategy to control, and it is used for tunneling project to reduce cut blas

Abstract: An intelligent car garage-moving device based on single-chip microcomputer control, including: a car carrying board, a stereo frame, a shuttle vehicle and a car storage board. The shuttle vehicle includes a running motor, a screw rod, a car lifting board, a supporting rod, a pull rod transmission mechanism, a roller, a guide roller, a car lifting motor and speed reducer, an output shaft gear, a guide roller and a rack. The car lifting motor drives the screw rod to rotate and the pull rod transmission mechanism and the car lifting board to move. The running motor drives the output shaft gear to rotate, and engagement movement of the output shaft gear and the rack drives the shuttle vehicle to move transversely. Though shuttling back and forth of the shuttle vehicle between the car storage board and the car carrying board, the device achieves transverse movement of the car.
