In this paper, discrete orthonormal Stockwell transform (DOST)-based vibration imaging is proposed as a preprocessing step for supporting load and rotational speed invariant scenarios for signals of various health conditions. For any health condition... Read More about Bearing fault diagnosis under variable rotational speeds using Stockwell transform-based vibration imaging and transfer learning..
