Acoustic Emission Signal Classification in Condition Monitoring Using the Kolmogorov-Smirnov Statistic. [PDF]

open access: yes, 2001
Acoustic emission (AE) measurement at the bearings of rotating machinery has become a useful tool for diagnosing incipient fault conditions. In particular, AE can be used to detect unwanted intermittent or partial rubbing between a rotating central ...

A Study of Computing Zero Crossing Methods and an Improved Proposal for EMG Signals

open access: yesIEEE Access, 2020
Zero crossings are a practical and efficient feature to approximate the frequency of a sampled series of data. Some research describes in different ways how to compute the zero crossings feature starting from its definition, and in some of them, a ...

Classification of Induced Magnetic Field Signals for the Microstructural Characterization of Sigma Phase in Duplex Stainless Steels

open access: yesMetals, 2016
Duplex stainless steels present excellent mechanical and corrosion resistance properties. However, when heat treated at temperatures above 600 ∘ C, the undesirable tertiary sigma phase is formed.
