Research on Geometric Design Standards for Freeways under a Fully Autonomous Driving Environment
Applied Sciences, 2022 The formulation of the current geometric design standard for freeways considers the influence of the “human-vehicles-road-environment” system. In the fully autonomous environment, the driver has been liberated from the system, which means that the ...

The Distance and Interstellar Sight Line to GX 339−4 [PDF]
The Astrophysical Journal, 2004 The distance to the black hole binary GX339-4 remains a topic of debate. We examine high-resolution optical spectra of the NaD lines resolving the velocity structure along the line of sight. We find this to be complex, with at least nine components, mostly blue-shifted, spanning a velocity range of nearly 200km/s.
