Failure Prediction and Replacement Strategies for Smart Electricity Meters Based on Field Failure Observation.

It is helpful to have a replacement strategy by predicting the number of failures of in-service electricity meters. This paper presents a failure number prediction method for smart electricity meters based on on-site fault data. The prediction model was constructed by combining Weibull distribution with odds ratios, then the distribution parameters, failure prediction number, and confidence intervals of prediction number were calculated.

Electrodeposited Co-Substituted LaFeO for Enhancing the Photoelectrochemical Activity of BiVO.

Co-substituted LaFeO was electrodeposited on the surface of BiVO as a co-catalyst to enhance the water splitting performance. Compared to bare BiVO, the BiVO/Co-LaFeO composite photoanode shows a water oxidation photocurrent of 3.4 mA/cm at 1.
