Vibration analysis for conditional preventive maintenance is an essential tool for the industry.The vibration signals sensored, collected and analyzed can Downstems provide information about the state of an induction motor.Appropriate processing of these vibratory signals leads to define a normal or abnormal state of the whole rotating machinery, o
To solve the leakage problem of concrete cracking and seepage in the freezing shaft lining of deep topsoil, it is proposed to use hybrid fibers and Extractors micro expansion high-performance concrete.Based on the normal concrete mix ratio of the frozen shaft lining, the orthogonal test method was used to investigate the effect of the water-to-bind
Cardiac auscultation is an accessible diagnostic screening tool that can help to identify patients with heart murmurs, who may need follow-up diagnostic screening and treatment for abnormal cardiac function.However, experts are needed to interpret the heart sounds, limiting the accessibility of cardiac auscultation in resource-constrained environme
