This paper presents a tuned Vacuum Cleaners positive position feedback controller (TPPF) to overcome the dual high peaks of the classical PPF.This control signal is merged with a proportional-derivative (PD) control signal to suppress the vibrations of a constant-stiffness 16-poles rotor active magnetic bearings (AMBs) system.Another benefit of the
Abstract Background Preeclampsia (PE), as a multisystem disorder, is associated with maternal hypertension and proteinuria.Apoptosis seems to be involved in the pathophysiology of PE, although its precise pathogenic mechanisms are not well established.In this study, we aimed to identify the association between maternal TP53-rs1042522, P21-rs1801270
Based on the existing acknowledgment that space charge modulates AC and DC breakdown of insulating materials, this investigation promotes the related investigation into the situations of more complex electrical stress, i.e., AC-DC combined voltages.Experimentally, the AC-DC breakdown characteristics of oil impregnated paper insulation were systemat
A firing control scheme for WALNUT OIL a three-phase fully controlled thyristor bridge dual-converter is described.By adapting the cosine wave crossing method, in the scheme, the converter operates as a linear power amplifier.The firing circuit has a fast response for triggering Valves angle correction.The scheme requires minimum number of integrat
Regenerated rice, characterized by single planting and double harvesting, saves labor and costs, significantly contributing to global food security.Hyperspectral imaging technology, which integrates image and spectral data, provides comprehensive, non-destructive, and pollution-free vegetation canopy analysis, making it highly effective for crop nu
