The world is currently dealing with the aftermath of the coronavirus disease 2019 (COVID-19) pandemic, which has resulted in momentous changes, the likes of which had not been witnessed within the previous century.These adverse events and Grinders the resulting uncertainty have posed enormous challenges to organizations, and many are on the verge o
The emerging BeiDou navigation satellite system has contributed to global precise positioning and has recently moved toward space-borne applications.However, the contribution of BeiDou on LEO orbit determination applications is limited by the poor precision of the GEO satellite orbit and clock products.Current researches suggest that BeiDou GEO sat
Condition monitoring of lubricating oil is an effective method for early detection of abnormalities in rotating machinery in plants.In this research, a new monitoring technique for lubricant degradation using terahertz waves, which are electromagnetic waves located in the boundary region between light and radio waves, is Betaine HCl developed based
Ensemble local mean decomposition has been gradually introduced into mechanical vibration signal processing due to its excellent performance in electroencephalogram signal analysis.However, Garlands an unsatisfactory problem is that ensemble local mean decomposition cannot effectively process vibration signals of complex mechanical system due to th
