Weak rail-surface defects are difficult to detect because their localized evidence can be attenuated during downsampling and confused with structured rail texture. Across 2895 training and validation images, the low-, mid-, and high-frequency bands contain 97.23 %, 2.04 %, and 0.73 % of the whole-image spectral energy,...

Hollow coils with complex structures are very common in electrical equipment and sensors. Additionally, the responses at different frequencies are an important characteristic of the coils. However, it is quite challenging to divide the irregular coils with fine windings (thousands of turns and wire diameter less than 0...

Distributed multichannel active noise control (ANC) is scalable, but filtered-x least-mean-square updates are highly sensitive to impulsive disturbances. This paper proposes a robust augmented-diffusion filtered-x maximum correntropy criterion algorithm (R-ADFxMCC). It keeps the fixed admissible combination of augmente...
The secondary circuit of voltage transformers in 110kV substations exhibits multiple fault categories with strongly coupled characteristics. Conventional detection methods that rely on predefined feature templates often fail to capture the intrinsic nature of these faults. To address this issue, this paper proposes a f...
