Abstract:
... Construction and maintenance of road pavements are both expensive and environmentally unfriendly. The prolongation of pavement life can reduce material consumption and produce a cleaning effect. This study attempts to propose a lateral control scheme for autonomous vehicles that aims at maximizing pavement life. In the key unit of the scheme, the trajectory-oriented method and fatigue damage-orien ...

Abstract:
... Lipstick is a kind of popular cosmetic, which can give the lip a beautiful color and improve its appearance. The problem is that dye molecules would be in contact with the skin, whereas the lipstick made with dyed CNCs (CNC-lipstick) would reduce the contact. Herein, we demonstrated that the deficiency of color migration can be overcome by using the cellulose nanocrystal (CNC) dye to replace conve ...
