Aerodynamic forces on high speed multi-hulled marine vehicles [PDF]

open access: yes, 2008
The need for high-speed high-payload craft has led to a considerable interest in vehicles capable of bridging the gap between conventional ships and aircraft. One such concept uses the forward motion of the craft to create aerodynamic forces on a wing-

High-Speed Autonomous Drifting With Deep Reinforcement Learning [PDF]

open access: yesIEEE Robotics and Automation Letters, 2020
Drifting is a complicated task for autonomous vehicle control. Most traditional methods in this area are based on motion equations derived by the understanding of vehicle dynamics, which is difficult to be modeled precisely.

Influence of unsupported sleepers on the dynamic stability of ballasted bed based on wheelset impact tests

open access: yesRailway Engineering Science, 2023
The unsupported sleeper can change the load characteristics of ballast particles and thus affect the dynamic stability of a ballasted bed. In this work, a laboratory test was constructed on a ballasted track containing unsupported sleepers. The ballasted
