Abstract: The present disclosure relates to a fingerprint identification method, device, an electronic apparatus and a storage medium. The fingerprint identification method includes: capturing a fingerprint by a fingerprint sensor, identifying matching pairs of minutiae between the captured fingerprint and a reference fingerprint; calculating a first matching result based on the minutia matching pairs; identifying minutia surrounding features for each minutia of the captured fingerprint in the minutia matching pairs; determining, for each minutia in the minutia matching pairs, whether the minutia surrounding features of the captured fingerprint match with minutia surrounding features of the reference fingerprint; calculating a second matching result based on the determination; and generating an identification result based on the first matching result and the second matching result.

Abstract: In a file repair method for a user equipment (UE), the UE receives a target file multicasted by a network side in a file download transmission (FDT) manner. The method includes transmitting, by the UE, a multicast attempt repair request for the target file to the network side in a first time period after determining that the target file needs to be repaired, where the first time period does not exceed a time period of a Back-off time of a current session, receiving, by the UE, a feedback message transmitted by the network side, where the feedback message instructs the UE to perform multicast repair, and performing, by the UE, the multicast repair on the target file in response to the received feedback message.

Abstract: The disclosure provides methods for transmitting and receiving video data, and a terminal device and a server. The server layers an original video into a plurality of video data streams, embeds extended information including feature information of a video data stream in a specified video data stream and transmits the plurality of video data streams to corresponding channels respectively for transmitting. A multicast prediction model in the terminal device may output a multicast access strategy based on the feature information of the video data stream and user experience information of the currently played video, and then a multicast combination currently accessed by the terminal device is adjusted based on the multicast access strategy to obtain a better multicast combination in the current network transmission environment, such that video data streams of corresponding quantities and quality are received.

Abstract: A user terminal apparatus includes an alarm; a collector including one or more sensors configured to collect characteristic data of a target object; and a controller configured to obtain a terminal-side exception judgment result by inputting the characteristic data into a terminal-side exception diagnosis model, in response to the terminal-side exception judgment result indicating that the characteristic data is abnormal, transmit the characteristic data to a cloud server, receive diagnostic information from the cloud server, and based on the received diagnostic information, update at least one of a terminal-side multi-classification model or the terminal-side exception diagnosis model, or control the alarm to issue an alarm signal indicating that the characteristic data is abnormal.

Abstract: A monitoring system for air conditioning systems based on distributed power generation and an air conditioning system using same. The monitoring system for air conditioning systems comprises a distributed power generation monitoring subsystem, a heating and ventilation energy management subsystem and a main monitoring system. The distributed power generation monitoring subsystem and the heating and ventilation energy management subsystem respectively monitor power generation status information of a distributed power generation device in an air conditioning system based on distributed power generation and power consumption status information of inherent devices in the system. The main monitoring system acquires monitoring data of the two subsystems by using a uniform first transmission protocol.
