Abstract: Unmanned aerial vehicle (UAV) technology was introduced in traffic surveillance in sparse road networks, and a UAV allocation method with/without UAV continuous flight distance constraint was proposed. First, the method ...

Abstract: To elucidate the frost heaving mechanism of subgrade, as well as reduce cracking, subsidence, and mudding due to water freezing and thawing in seasonally frozen regions, temperature sensors were embedded in the subgrade ...

Abstract: The use of permselective spacers in reverse electrodialysis (RED) stack introduces a more severe concentration polarization phenomenon at membrane–solution interfaces in spite of effectively suppressing the spacer shadow ...

Abstract: Composite pistons are often used in heavy duty diesel engines due to its good reliability and durability. Owing to the alternating loads, fretting wear usually happens on the mating surfaces between piston crown and skirt. ...
