Investigation of effects on the contact condition and the collision behaviour of a wheelset with a flat set on a roller rig by the shape at the edge of the wheel flat

We firstly executed bench tests of a bogie having the wheelset with a wheel flat installed on the roller rig.A wheel flat of 75 mm was prepared on the wheel tread and the front edge of the wheel flat was rounded by the grinding work.By making the radius of the front edge large, the maximum vertical acceleration of an tiny gum squares axlebox decrea

Semantic Feature Learning via Dual Sequences for Defect Prediction

Software defect prediction (SDP) can help developers reasonably allocate limited resources for locating bugs and prioritizing their testing efforts.Existing methods often serialize an Abstract Syntax Tree vuori sunrise crew (AST) obtained from the program source code into a token sequence, which is then inputted into the deep learning model to lear
