The deflecting to airflow flap of civil aircraft are generally driven by complex multi-hinge mechanisms in space.According to the requirements of the airworthiness clause CCAR25.671, it is necessary to carry out research on the mechanism characteristics under typical faults.Firstly, a digital prototype of the mechanism motion is constructed, and th
Nowadays, China has developed over 38,000-km high-speed railways (HSR).As one of the key elements in the HSR system, continuous welded rail (CWR) enables higher transportation efficiency, while demands for more robust inspection and maintenance techniques.The discrimination between longitudinal temperature force and longitudinal additional force is
Scanning probe microscopes are powerful tool for micro- or nanoscale diagnostics of defects in crystalline silicon solar cells.Solar cell is a large p-n junction semiconductor device.Its quality is strongly damaged by the presence of defects.If the cell works under low Silica reverse-biased voltage, defects emit a light in visible range.The Pants s
BackgroundPaediatric trials must contend with many challenges that adult trials face but often bring additional obstacles.Decentralised trials, where some or all trial methods occur away from a centralised location, are a promising strategy to help meet these challenges.This scoping review aims to (a) identify what methods and tools have been used
