Abstract: Based on momentum conservation principle of space manipulator, this paper presents precapture configuration of space manipulator capturing object. Two unique precapture configurations, “straight-arm capture” (SAC) and ...

Abstract: A multiscale model is established for effective diffusion coefficient of chloride ions in cement-based composite materials. The model takes into account the relationship between the diffusivity and microstructure of ...

Abstract: Bone tissue engineering is an emerging field providing viable substitutes for bone regeneration. Freeform fabrication provides an effective process tool to manufacture scaffolds with complex shapes ...

Abstract: According to the application characteristics of low-earth-orbit satellite-borne global positioning system (GPS) receiver, the influence of GPS measurement data error on cycle-slip detection is analyzed. Then a modified ...

Abstract: Residual macrostresses in a multipass circumferentially butt-welded P91 ferritic steel pipe have been determined numerically and experimentally. The welded joint in a pipe with an outer diameter ...
