Abstract: In this paper, a new algorithm is employed in global positioning system (GPS) rapid positioning using several-epoch single-frequency phase data. First, we define the double-

Abstract: The tribological performance of scrolls lubricated with CO2/oil mixture is investigated using a combination of the mixed lubrication model and the homogeneous model. The physical characteristics of the CO2/oil mixture were ...

Abstract: Graphene/fullerene carbon–based nanoparticles exhibit excellent tribological properties in solid–liquid two-phase lubrication systems. However, the tribological mechanism still lacks profound insights into dynamic friction ...

Abstract: Diffusion shaped holes are widely used on aero-engine turbine blades for film cooling. The effect of the spanwise-expansion angle and spanwise width of the hole exit on the film cooling effectiveness of diffusion shaped ...
