Negentropy Spectrum Decomposition and Its Application in Compound Fault Diagnosis of Rolling Bearing
Entropy, 2019 The rolling bearings often suffer from compound fault in practice. Compared with single fault, compound fault contains multiple fault features that are coupled together and make it difficult to detect and extract all fault features by traditional methods

Compound Fault Diagnosis Method of Modular Multilevel Converter Based on Improved Capsule Network
IEEE Access, 2022 When submodule (SM) compound fault occurs in the Modular multilevel converter (MMC), the time-domain waveform characteristics of output current and internal circuiting current of MMC are not obvious, especially on the condition of high-level MMC.

Compound Fault Feature Extraction of Rolling Bearing Acoustic Signals Based on AVMD-IMVO-MCKD
Sensors, 2022 The compound fault acoustic signal of a rolling bearing has the characteristics of a varying noise mixture, a low signal-to-noise ratio (SNR), and nonlinearity, which makes it difficult to separate and extract exactly the fault features of compound fault

Semi-Supervised Sparse Coding [PDF]
, 2014 Sparse coding approximates the data sample as a sparse linear combination of some basic codewords and uses the sparse codes as new presentations. In this paper, we investigate learning discriminative sparse codes by sparse coding in a semi-supervised ...

The Responsibility Gap in Corporate Crime [PDF]
, 2017 In many cases of criminality within large corporations, senior management does not commit the operative offense — or conspire or assist in it — but nonetheless bears serious responsibility for the crime.
