Abstract: A method and a system for identifying an operating status of an electrical appliance based on non-intrusive load monitoring are provided. The method includes the following steps. Total power consumption history data of a target field and appliance power consumption history data of target electrical appliances are obtained. The appliance power consumption history data of each target electrical appliance is converted into a binary data set. The total power consumption history data is clustered into cluster samples to obtain first feature data sets, which are then dimensionally reduced into second feature data sets, and a machine learning model is trained by using the second feature data sets and the binary data sets of the target electrical appliances to establish an operation identification model for the target electrical appliances. The operation identification model identifies an operating status of the target electrical appliances according to total power consumption data.

Abstract: Methods for producing virus particles and viral antigens with simplified glycosylation profiles, such as mono-glycosylated forms of HIV, HCV, Dengue virus, West Nile virus and influenza virus. When used as targets for vaccine production, the conserved nature of such sites generate vaccines that are less sensitive to viral mutations. Such methods may include the use of glycosylation inhibitors for production of viruses or viral antigens with simplified glycosylation profiles.
