A novel arc-tooth-trace cycloid cylindrical gear is presented in this paper. According to the principles of gear meshing and the analysis of the basic gear geometric parameters, the profile equations of the gear tooth are deduced. The tooth trace of the gear is a segment of a circular arc, and the tooth profile is divided into two parts by the pitch circle, the first part of the tooth profile outside...
The Nonlinear Output Frequency Response Functions (NOFRFs) are concepts proposed for the frequency analysis of nonlinear systems, and they have been essential for applications of damage detection in mechanical and civil engineering, etc. Although they have been evaluated by the Least-Square method and the associated linear equations based method, there is little research about the comparative study...
In this article, it is explored that how to design and implement a temporal and spatial early warning model for AIDS spread on sex in Kunming (Yunnan province) by using ABM and making spatial analysis by developing in ArcEngine and ArcSDE. Obviously, the method of integration between ABM models and GIS technology is also clarified as a key technology in the text. As a result, based on a spreading...
At the age of post-Kyoto Protocol, international forestry carbon sequestration project not only has strongly achieved the form of harmoniously developing between economy and environment conservancy in developing countries, but also is promoting the relative research on theory and technology in Forestry Carbon Sequestration. And this paper has discussed that how to establish the Geo-Spatial Model of...
