Fault analysis of industrial robots based on self-organised critical theory
The Journal of Engineering, 2019 Industrial robots, as a structurally sophisticated mechatronics system, have a high cost of routine maintenance and repair. Repairs after fault require the corresponding manpower and material resources, and have hysteresis.

Who Watches the Watchers: Attacking Glitch Detection Circuits
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Over the last decades, fault injection attacks have been demonstrated to be an effective method for breaking the security of electronic devices. Some types of fault injection attacks, like clock and voltage glitching, require very few resources by the ...

Fault Analysis Method Considering Dual-Sequence Current Control of VSCs under Unbalanced Faults
Energies, 2018 Voltage source converters (VSCs) are able to provide both positive- and negative-sequence short circuit currents under unbalanced faults. Their short circuit responses can be significantly different from those of conventional synchronous generators. This

Using Matlab/Simulink Software Package to Investigate Fault Behaviors in HVDC System
Mathematics, 2022 Existing studies show that several performance issues will arise in the HVDC link during the three phase-to-ground fault at the side of the inverter and that the DC voltage will oscillate around zero and will not affect the rectifier of the AC system ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
