Abstract: A novel configuration of the wind-driven spherical robot with multiple shapes is proposed, which can realize the multiple movement modes of rolling, bouncing, and flying by adjusting its external shape. The constraints, ...

Abstract: A key problem in road construction in cold regions is keeping permafrost stable, a requirement that cannot be satisfied by common asphalt concrete pavement. In this study, experiments on the thermal conductivity of diatomite ...

Abstract: A chimera Reynolds-averaged Navier-Stokes (RANS) method has been developed for time-domain simulation of transient flow induced by a ship approaching a berthing facility. The method solves the mean flow and turbulence ...

Abstract: In order to unveil the mechanical response of steel deck pavement, transient dynamic responses of the orthotropic steel deck pavement of large-span steel bridge were analyzed and calculated with FEM. First, the static and ...

Abstract: High-precision cable net reflectors are widely required for future communications and observations. Concerning the improvement of their surface accuracy, the active cable structure constructed by incorporating a piezoelectric ...

Abstract: This paper describes a prototype and analytical studies of a spherical rolling robot, a new design of a nonholonomic robot system. The spherical robot is driven together by an internal linear motor, continuously changing ...

Abstract: Offset-feed elliptical aperture reflectors have better mechanical and electrical performance than circular aperture reflectors and are an inevitable trend for the future development of high-precision space-borne antennas. ...
