Review of Post-Prognostics Decision-Making in Prognostics and Health Management
International Journal of Prognostics and Health Management, 2021 Mainly, the prognostics and health management (PHM) process is based on three processes: the data acquisition and health assessment process in which sensors signals are acquired and processed, the diagnostic and prognostic process in which the source of failure is detected and the remaining useful life (RUL) is predicted and finally the decision ...

Rolling Element Bearings Fault Diagnosis Based on a Novel Optimal Frequency Band Selection Scheme
IEEE Access, 2019 The squared envelope spectrum (SES) is one of the most effective methods in rolling element bearing fault diagnosis. Being a technique based on demodulation, the success of SES depends highly on the extraction of information caused by the bearings fault.
