Abstract: The Shields diagram remains the most widely used criterion for incipient motion of sediment. However its implicit nature makes applications rather inconvenient. By deploying Guo’s logarithmic matching method twice, this ...

Abstract: Due to joint clearance, a parallel manipulator’s end-effector exhibits position and orientation (or collectively referred to as pose) errors of various degrees. This paper aims to provide a ...

Abstract: The mechanical behavior of Martian regolith–structure interfaces is of great significance for the design of Mars rover and excavation tools, as well as for infrastructure construction for Mars exploration. This paper aims ...

Abstract: New formulations are presented for flow resistance and momentum flux in compound open channels. As implemented in the St. Venant equations, these formulations facilitate a physically enhanced approach to evaluating conveyance, ...

Abstract: Graphene nanosheets are produced in mass by Hummers method, accompanied with the emission of waste acid effluent with Mn2+, which should be reasonably recycled. Herein, Mn2+ was extracted into Mn3O4 nanoparticles by oxidation ...
