The invention relates to a data management method and system for federated cloud, and the method comprises the steps: obtaining an identity authentication request, carrying out the identity verification of a client, granting a data management authority to the client after the identity verification of the client is passed, and building the communication with the client. And receiving the updated local model and weighting the updated local model to generate a new global model, wherein the local model performs local model training on the local data sample through the client and exchanges parameters among different local models to obtain the updated local model. Based on the new global model and the data management authority, a first request instruction is received through the CSP, the execution authority of the client to the first request instruction is confirmed, the first request instruction is executed according to the execution authority, and the first request instruction is used for updating ...

A device for generating a droplet array, which comprises a substrate, a roller on the substrate, and a microgrooved chip on the outer surface of the roller, wherein a sealant is on a surface of the substrate close to the roller and the microgrooved chip comprises a chip body fitted to the roller and an array of microgrooves arranged on the chip body, the array of microgrooves consisting of a plurality of microgrooves arranged at intervals on the chip body. When the roller rolls, liquid between the substrate and the roller enters the microgrooves and forms droplets while the microgrooved chip detaches from the roller and combines with the sealant which seals the microgrooves, generating a droplet array. The device generates a droplet array having uniform droplet size, good repeatability. Further, the method is simple and highly efficient, and has broad application prospects in the fields of medicine and biology.

The invention discloses a router queuing delay detection method and device based on unsupervised learning, and relates to the technical field of wired networks. The router queuing delay detection method based on unsupervised learning comprises the following steps: generating a UDP (User Datagram Protocol) data packet pair, and transmitting the UDP data packet pair from a source address to a target address through a router to be detected; collecting time interval data of the UDP data packet pair; learning the collected time interval data by using an unsupervised learning Kmeans clustering algorithm to obtain a clustering result and a centroid; and calculating the queuing delay of the router to be tested. According to the method, the collected time interval data is learned through the Kmeans clustering algorithm, and the queuing delay of the router to be tested is calculated according to the clustering result and the centroid, so that the effect of accurately analyzing the queuing delay of ...
