The structure and composition of exhumed faults, and their implications for seismic processes [PDF]
, 2000 Field studies of faults exhumed from seismogenic depths provide useful data to constrain seismologic models of fault zone processes and properties. Data collected on the San Andreas Fault in the San Gabriel Mountains has shown that large-displacement ...

An application of adaptive fault-tolerant control to nano-spacecraft [PDF]
, 2014 Since nano-spacecraft are small, low cost and do not undergo the same rigor of testing as conventional spacecraft, they have a greater risk of failure.

Adaptive Minimum-Entropy Hybrid Compensation for Compound Faults of Non-Gaussian Stochastic Systems
IEEE Access, 2019 This study investigated minimum-entropy hybrid fault-tolerant control (FTC) theory for non-Gaussian stochastic systems with compound faults. After fuzzy linearization for the singular systems, the output probability density function (PDF) is generated by

Effects of actuator faults on large-scale wind turbine dynamics with an industry-standard controller [PDF]
E3S Web of ConferencesThe pitch actuator is a critical component of large-scale wind turbines with a high failure rate. Actuator faults significantly impact the dynamics of wind turbines, leading to increased loads on the turbine structure and reduced power output, thereby ...
