Research on bearing fault diagnosis of reciprocating compressors based on GMDE and MFO-MKELM algorithms by LI Yanyang, WANG Jindong, NING Liuyang, MA Lei

“…ObjectiveAiming at the problem that the bearing fault feature extraction is difficult and the recognition accuracy is not high due to the characteristics of local strong non-stationarity and nonlinearity of the vibration signal of reciprocating compressor bearing clearance, a new method based on GMDE and MFO-MKELM algorithm was proposed.MethodsFirst, spread on multiscale entropy in the process of coarse graining, the average coarse graining way to a certain extent, “neutralize” the dynamics of the original signal mutation behavior, and reduce the accuracy of the entropy analysis. A generalized multiscale entropy algorithm spread, application of the reciprocating compressor vibration signals of bearing clearance for fault feature extraction was proposed; then, the polynomial kernel function and the improved Gaussian kernel function were linearly combined to construct the multiple kernel extreme learning machine intelligent recognition algorithm, and the fault diagnosis research was carried out on the extracted feature vector set.ResultsSimulation results show that the recognition accuracy of the fault diagnosis method is as high as 98.6%, which effectively realizes the intelligent diagnosis of different types of bearing faults.…”

Association between cardiovascular health and markers of liver function: a cross-sectional study from NHANES 2005–2018 by Huang Yu, Tingyi Zhang, Yankun Liu, Wang Wang, Ziyi Guan, Ping Li

“…However, the relationship between CVH, as measured by Life’s Essential 8 (LE8), and liver function markers in the general population remains poorly understood.MethodsThis study analyzed data from 21,156 participants (aged ≥ 20) from the NHANES 2005–2018 to investigate the associations between CVH and liver function markers [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), albumin and AST/ALT ratio]. …”

Parameter Calculation and Rotor Structure Optimization Design of Solid Rotor Induction Motors by Hao Xu, Jinghong Zhao, Sinian Yan

“…Solid rotor induction motors have a solid body rotor, which leads to low efficiency and power factor, and currently, the rotor is mostly optimized by slotted and squirrel cage structures. A generalized multilayer analytical model for different rotor structures is established, which can consider the effects of rotor eddy currents and saturation, based on which a generalized equivalent circuit model is established. …”
