DOI: 10.1088/1361-6501/ad894e
Abstract: Sparsity measures (SMs) are effective tools for rotating machinery condition monitoring. However, under complex operating conditions, existing SMs often exhibit significant fluctuations, making it difficult to accurately detect early faults and monotonically represent the degradation… read more here.

DOI: 10.1109/jlt.2020.3041625
Abstract: The Vernier effect can amplify the sensitivity of the sensor, but its effective spectral range is usually limited to one free spectral range (FSR). Once the envelope shifts beyond one FSR, it will lead to… read more here.
