Fault Diagnosis of High-Voltage Circuit Breakers Using Mechanism Action Time and Hybrid Classifier
IEEE Access, 2019 Accurate fault diagnosis of high-voltage circuit breakers is crucial for the safety of power grids. Mechanism action time, though can reflect the state of high-voltage circuit breakers, is usually difficult to obtain, as multiple sensors are required for

Caregivers' perspectives of support needs for adolescents with fetal alcohol spectrum disorder
Children &Society, EarlyView.Abstract Research focused on fetal alcohol spectrum disorder (FASD) is often deficit‐focused, limiting a holistic understanding of individuals' support needs. Families of adolescents with FASD also struggle to access appropriate services. Using semi‐structured interviews, the current study explored the perspectives of seven caregivers of adolescents ...
