For the current applicable discussions on the idea of sample=overall in big data processing, this paper selects macro data from multi-source including influence factors of smart city from 17 districts and counties of Shanghai as an overall sample, and standardizes the data. Then, another sample is created from output of Principal Components Analysis (PCA). By comparing the two types of samples in...
With the development of information technology, since 1990s, E-Government has become a vital tool for government to change its ways of work. In this research, we took Xi'an and Nan Jing municipal's E-Government as example, using questionnaires to survey citizens' adoption of G2C model E-Government. Then we used structural equation model to explore what factors influence citizens' intention of using...
The paper uses cumulate percent method, ridit value method and ??very good day?? method, to analyzes data of atmosphere visibility in Guilin city from 1951 to 2006 year. The result shows that atmosphere visibility ascends in 1950s, reduces since 1960 year, and reduce speed is slower from 1981 to 2006 year than that from 1960 to 1979 year. The paper also concludes that as the observe criterion of atmosphere...
GPS-based synchronous phasor measurement technology is a powerful tool for the security and reliable operation of the inter-connected electric power system. This paper presents an ACO-based approach to optimize the phasor measurement unit (PMU) placement problem. The pheromone trail persistence coefficient adaptive adjustment mechanism and stochastic perturbing progress are introduced into the ant...
This paper studies the intra-cluster knowledge diffusion from the cognitive perspective. Borrowing the concept of schema from the social cognition, we proposed a cognitive community-based analytic framework. We then conducted a case study on a socks cluster in China, and an agent-based simulation to explore the dynamics of intra-cluster knowledge diffusion. The results indicate that the cluster's...
