Neither “Platformization” Nor “Infrastructuralization”: Government as a Platform in China by Jingyan Elaine Yuan, Yuchao Zhao

“…Through a case study of “the digital reform” in Zhejiang Province, and the affiliated smart city project—City Brain—in Hangzhou, the municipal capital, this study draws on data from participatory observations and interviews to (1) provide a historical context, in which “platformization” in urban governance is aimed to serve market-oriented socio-economic reforms; (2) argue that such “platformization” is shaped by the long-standing structural tension between centralization and localism, which has been renewed by digital data flows; and (3) understand the shifting public–private demarcation in social interactions and arrangements to deflect continual frictions between the state, local agents, and platforms in the domain of digital governance.…”

Research of the Effect of Tooth Surface Topography on Dynamics Characteristic by Chen Qi, Li Hao, Wang Yadong, Wu Yanming

“…Based on three sets of gearbox with the same tooth surface accuracy level,the tooth contour is measured in the cases of oil lubrication,grease lubrication and dry friction with the equal load and running time,and the corresponding fractal dimension is got by the methodology of structural function. The result shows that when it is oil lubrication,the fractal dimension is the largest and the variation ranges of fractal dimension is the smallest before and after the experiment,which indicates that the less tooth wear leads to more stable dynamic performance. …”
