A Method for Real-Time Prediction of the Probability of Voltage Sag Duration Based on Harmonic Footprint

IEEE Access, 2022
In this paper, a novel method for real-time prediction of voltage sag duration is proposed. It is based on the recently introduced new characteristic of voltage sag, named harmonic footprint, and is formulated using a logistic regression model.

Thermal characteristic analysis of Z-axis guideway based on thermal contact resistance

Advances in Mechanical Engineering, 2018
The Z-axis feeding system of large computer numerical control (CNC) gear grinding machine tools generates lots of heat during processing, which leads to tilt and pitch deformation of the Z-axis guideway and reduces the machining accuracy. In view of this
