Abstract: Recycled polyethylene (PE) has been used in asphalt modification for sustainability benefits but shows complex interaction with asphalt matrix. This study investigated compatibility and self-healing properties of asphalt/PE ...

Abstract: The study proposes a method for the trajectory tracking control of a fixed-wing unmanned aerial vehicle (UAV) based on the deep deterministic policy gradient (DDPG). First, the problem of controlling the trajectory of a ...

Abstract: A rapid path planning (RPP) method that fast generates suboptimal zero propellant maneuver (ZPM) paths was proposed previously, and to further enhance the planning performance, the differential flatness of the model is ...

Abstract: The mean texture depth (MTD) of asphalt pavement surface is an important indicator of skid resistance of asphalt pavement. This paper aimed to analyze the wearing behavior of asphalt mixtures under repetitive tire loads ...

Abstract: Different from the current studies on the impulsive rendezvous which are mainly normal propellant-optimal or time-optimal designs, the safety-optimal impulsive rendezvous with consideration of practical trajectory uncertainties ...

Abstract: The zero-propellant maneuver (ZPM) is an advanced space station large-angle attitude maneuver technique using control momentum gyroscopes (CMGs), and rapid path planning (RPP) enhances its performance. This paper proposes ...
