Abstract: Provided is a cross-machine few-shot fault diagnosis method based on a retrospective prototypical network (RPN), which belongs to the technical field of fault diagnosis. First of all, through a multi-scale hybrid dilated convolutional feature extraction module, highly abstract sample features are extracted from a vibration signal acquired in a complex scenario. Then, a retrospective prototype representation and update method is proposed to optimize a class prototype with internal structures of data, more accurately reflecting a complex distribution of a class, and effectively reducing prototype oscillation and feature distribution differences between batches. In addition, a new similarity evaluation method, namely a central difference metric (CDM), is proposed to calculate a difference between the internal structures of the data, providing a more flexible similarity evaluation tool for a few-shot diagnosis task.

Abstract: Systems and methods comprising a metering device located on an electricity distribution grid, the metering device comprising one or more processors and memory. The metering device can detect a drop in characteristic of electricity below a threshold indicating a fault on the electricity distribution grid. The metering device can generate, responsive to the drop in the characteristic of electricity below the threshold, a time series of a rate of change of the characteristic of electricity for a predetermined number of cycles subsequent to the detection of the drop. The metering device can determine, based on a comparison of the time series of the rate of change with a predetermined pattern, a location of the metering device on the electricity distribution grid relative to a location of the fault on the electricity distribution grid.

Abstract: A latency-oriented Service Level Optimization system for multi-tenant databases. Latency's negative effect on Quality of Service is expressed in terms of a latency impact function to provide a latency impact-oriented SLO-guaranteed system that enables a database system to support multi-tenant latency-impact targets in a cost-effective fashion. In contrast to traditional latency management based on percentile guarantees, the present invention manages latency based on the latency probability density function for all latency values. Cost-effective management is attained through latency impact-oriented capacity planning and real-time latency impact target enforcement. The capacity planning estimates the feasibility of latency-impact targets while the target enforcement tracks and regulates the per-connection query latency distribution needed for accurate latency-impact target guarantee, avoiding both under-provisioning and over-provisioning.
