Based on uniform design method, correlations between five flux components and Sn-9Zn/Cu wetting were studied. Take lauric acid, propylene glycol, decanol, polyethylene glycol 2000 and zinc chloride as independent variables Xi, wetting spreading area as function Y in the experiment. Every variable is divided into fifteen levels. Using computer software UST4.0, the experimental data were gradually statistical...
To reuse 3D CAD models more efficiently, a 3D CAD model retrieval approach which combines Genetic Algorithm (GA) and Ant Colony Optimization (ACO) is proposed. A CAD model is represented by feature dependency graph (FDG). The similar sub-graphs in the corresponding FDGs of different models are obtained according to polymorphic combinatorial GA and ACO. GA is adopted to obtain suboptimal solutions...
