Blind Source Separation Method for Bearing Vibration Signals
IEEE Access, 2018 In underdetermined blind source separation (UBSS) of vibration signals, the estimation of the mixing matrix is often affected by noise and by the type of the used clustering algorithm.

Data-Driven Fault Diagnosis Analysis and Open-Set Classification of Time-Series Data [PDF]
Control Engineering Practice, 121, 105006 (2022), 2020 Fault diagnosis of dynamic systems is done by detecting changes in time-series data, for example residuals, caused by system degradation and faulty components. The use of general-purpose multi-class classification methods for fault diagnosis is complicated by imbalanced training data and unknown fault classes.

Decentralized Validation for Non-malicious Arbitrary Fault Tolerance in Paxos [PDF]
WTF '19: Proceedings of the XX Fault Tolerance Workshop, SBC,
2019, 34-47, 2020 Fault-tolerant distributed systems offer high reliability because even if faults in their components occur, they do not exhibit erroneous behavior. Depending on the fault model adopted, hardware and software errors that do not result in a process crashing are usually not tolerated. To tolerate these rather common failures the usual solution is to adopt

Connecting the Dots: A Comprehensive Literature Review on Low and Medium-Voltage Cables, Fault Types, and Digital Signal Processing Techniques for Fault Location [PDF]
arXiv, 2023 The review begins with an exploration of acceptable cable types guided by local standards. It then investigates typical cable faults, including insulation degradation, conductor faults, and ground faults, providing insights into their characteristics, causes, and detection methods.

Fault Injection as an Oscilloscope: Fault Correlation Analysis [PDF]
IACR Transactions on Cryptographic Hardware and Embedded Systems, 2020 Fault Injection (FI) attacks have become a practical threat to modern cryptographic implementations. Such attacks have recently focused more on exploitation of implementation-centric and device-specific properties of the faults. In this paper, we consider the parallel between SCA attacks and FI attacks; specifically, that many FI attacks rely on the ...

A Survey on Software Fault Localization
IEEE Transactions on Software Engineering, 2016 Software fault localization, the act of identifying the locations of faults in a program, is widely recognized to be one of the most tedious, time consuming, and expensive - yet equally critical - activities in program debugging.
