The modified Galerkin's method was used to discretize partial differential Eqs. The mine hoisting system was used to the example to analysis the relation between the load, velocity and transverse vibration of rope. The in situ tests were illustrated to evaluate the proposed mathematical model. The results showed that the modeling method can well represent the transverse vibration of rope.展开更多

This process calls for a high degree of control and coordination, which must be effected by the horizontal, amacrine, and interplexiform cells, gap junctions and the feedback provided from the V1 area to the Lateral Geniculate Nucleus (LGN). But, as the ILM covers the optic disc but not the fovea, the latter must produce the blind spot and the rays reflected radially from the centroid must have the same centre as the Muller cells in order to be able to channel them to the RPE cells.展开更多
