Kinetic effects in dynamic wetting [PDF]
, 2017 The maximum speed at which a liquid can wet a solid is limited by the need to displace gas lubrication films in front of the moving contact line. The characteristic height of these films is often comparable to the mean free path in the gas so that ...

Gear wear process monitoring using a sideband estimator based on modulation signal bispectrum [PDF]
, 2017 As one of the most common gear failure modes, tooth wear can produce nonlinear modulation sidebands in the vibration frequency spectrum. However, limited research has been reported in monitoring the gear wear based on vibration due to the lack of tools ...
