Based on the radial basis interpolation function algorithm, the proposed method can transform the original optimized problem into nonsingular linear problem by adding one-order term and affine differentiable condition. This linear system can get the steady unique solution by choosing suitable kernel function. Furthermore, the proposed method demonstrates how to set up the radial basis function in the target image so as to achieve supports to adopt the backward re-sampling technology accordingly which could gain the very slippery warping image. Theexperimental result shows that the proposed method can implement smooth and gradual image warping with multi-anchor points' accurate interpolation.展开更多

In this paper, sap2000 is used to analyze the overall lifting technology of a 72*144m long-span steel structure. The grid structure is divided into two areas for lifting, and there are four different areas for different repair welding areas and lifting methods. By analyzing the indexes of stress, deformation and internal force of structure construction under different construction zoning schemes, the best construction scheme can be selected. The calculation results show that the construction deformation of the second scheme is the smallest, with the final deformation of 49.164mm, the maximum stress ratio of the components after construction being 0.204, and the stress ratio of the components under the load of 1.3D+1.5L being 0.8098, which is basically the same as the stress ratio of 0.80 obtained by the one-time loading design, so the second scheme is finally selected.展开更多
