A new reliability analysis approach was presented based on three-dimensional Morgenstem-Price method to investigate three-dimensional effect of landslide in stability analyses. To obtain the reliability index, Support Vector Machine （SVM） was applied to approximate the performance function. The time-consuming of this approach is only 0.028% of that using Monte-Carlo method at the same computation accuracy. Also, the influence of time effect of shearing strength parameters of slope soils on the long-term reliability of three-dimensional slopes was investigated by this new approach. It is found that the reliability index of the slope would decrease by 52.54% and the failure probability would increase from 0.000 705% to 1.966%. In the end, the impact of variation coefficients of c andfon reliability index of slopes was taken into discussion and the changing trend was observed.展开更多

Facing the challenge of the selection of the proper function class with polynomial smooth techniques applied to support vector regression models, this study takes cubic spline interpolation to generate a new polynomial smooth function ｜×｜ε^ 2, in g-insensitive support vector regression. Theoretical analysis shows that Sε^2 -function is better than pε^2 -function in properties, and the approximation accuracy of the proposed smoothing function is two order higher than that of classical pε^2 -function. The experimental data shows the efficiency of the new approach.展开更多

This is the comprehensive implementation of urban and rural development to increase industrial agriculture, move the city to support the countryside, accelerate urbanization and narrow the gap between urban and rural areas. To solve the ＂three rural issues＂, the comprehensive construction ofa well-offsociety, has a very important strategic role to ease the contradiction of China＇s rural and urban ecnomic structure. In the process of building a new socialist countryside, the financial policy, as an important means ofmacroeconomic regulation and control, should play a leading role in solving the effective allocation ＆funds. Due to various factors affected by the current supply of rural financial market constraints, system defects and environmental constraints, there is a large gap between the level of the existing rural financial services and the requirements of the new rural construction which is to be improved urgently.展开更多

A number of experiments and a comparison between similar softwares, showed that the algorithm is efficient and feasible. Moreover, different features of riBS were studied for different kinds of materials, such as PS and nylon. The research findings indicate that automatically adding HBS can significantly improve the accuracy of the parts, and that the algorithm for generating HBS is efficient and precise.展开更多
