Routine pavement inspection is crucial to keep roads safe and reduce traffic accidents.However, traditional practices in pavement inspection are labour-intensive and time-consuming.Mobile laser scanning (MLS) has proven a rapid way for collecting a large number of highly dense point clouds covering roadway surfaces.Handling a huge amount of unstruc

Deep learning methods have been introduced for fault diagnosis of rotating machinery.Most methods have good performance when processing bearing data at a certain rotating speed.However, most rotating machinery in industrial practice has variable working speed.When processing the bearing data with variable rotating speed, the existing methods have l

The superstructure of a coastal bridge Tablerunners is prone to overturn or unseating under a catastrophic tsunami, which seriously affects the post-disaster emergency rescue.In this paper, we establish a safety assessment framework for the superstructure of a bridge with a box girder under a potential landslide tsunami, and apply it to an in-servi
