Development of Broken Rotor Bar Fault Diagnosis Method with Sum of Weighted Fourier Series Coefficients Square

open access: yesEnergies, 2022
This study proposes a broken rotor bar (BRB) fault diagnosis method for an induction motor using the sum of the weighted Fourier series coefficients squares of a complex current as a diagnosis signal.

Analog circuit fault diagnosis based on enhanced Harris Hawks optimization algorithm with RBF neutral network

open access: yesEngineering Reports, 2023
Circuit faults are caused by the change of device parameters in the analog circuit. Aiming at the problems that the fault feature extraction is difficult and the fault signal cannot be effectively classified, an enhanced Harris Hawks algorithm is ...

Incorporating Modern Fault Ride-Through Standards into the Short-Circuit Calculation of Distribution Networks

open access: yesSensors, 2023
Modern fault ride-through (FRT) standards in many countries require distributed generators to remain connected for a specified period during the fault by providing reactive current, to support voltage and prevent a massive renewable outage.

Hard fault analysis of Trivium [PDF]

open access: yesInformation Sciences, 2013
Fault analysis is a powerful attack to stream ciphers. Up to now, the major idea of fault analysis is to simplify the cipher system by injecting some soft faults. We call it soft fault analysis. As a hardware-oriented stream cipher, Trivium is weak under soft fault analysis.

INCLUDING SYSTEMATIC FAULTS INTO FAULT TREE ANALYSIS [PDF]

open access: yesIFAC Proceedings Volumes, 2006
: Fault Tree Analysis (FTA) is a technique widely used for fault forecasting of physical systems. Although FTA is considered a well established safety analysis technique, paradoxically classical Fault Trees include only random faults. However, in modem automated systems, undesirable events arise not only from random hardware faults but also from ...

Fault analysis of Kuznyechik

open access: yesМатематические вопросы криптографии, 2016
Проводится анализ двух атак на шифр Кузнечик методом искажений. Показано, что если атакующий может искажать случайный байт в 7-м и 8-м раундах, то с помощью разностного метода он может найти ключ, используя в среднем 4 искажения. Другая атака относится к случаю, когда шифр имеет секретный S-бокс, и позволяет в модели искажений типа залипания байта на 0
