A trunnion joint is modeled as a circular plate with a rotational spring at the outer peripheral portion to resist rotation. Asymmetrical bending deflection is produced when an external moment acts on the inner side of the circular plate. The equations of the circular plate with a special outer peripheral boundary condition are derived. Choosing the stiffness of the rotational spring and the ratio...
High-temperature permafrost has wondrous susceptive to construction disturbance. There is observably influence by hydration heat of cast-in-situ concrete on permafrost-pile in high-temperature permafrost regions. Based on numerical simulation experiments and model tests; the influence of the hydration heat of cast-in-situ concrete on temperature field and stability of soil-pile in high-temperature...
As a critical unit of computer vision (CV) based applications, image segmentation is quite worth studying. Hybrid method of spatial credibilistic clustering and particle swarm optimization (SCCPSO) is a novel effective segmentation method. It's proved to produce better results than other common methods. In this paper, SCCPSO is further investigated by discussing several key points such as membership...
