Cao, Yuanzhang (author), Guo, Liping (author)The chloride and sulfate exist together in real environment, no matter marine or salts lakes, and the ratio of the chloride to sulfate is varied. To precisely predict the concrete durability under real environment, this paper mainly investigated the influence of sulfate on chloride ions diffuse into hardened cement paste. The Minitab software...conference paper 2021

Guo, Renzhong (author), Li, Lin (author), He, Biao (author), Luo, Ping (author), Ying, Shen (author), Zhao, Zhigang (author), Jiang, Renrong (author)A rapid urban growth in China urges to extend land use to land space use in three dimensions due to limited land resource in cities. 3D cadastre is emerging as an effective means to support such a demands for using urban land in a way of three dimensions. Shenzhen, located in the south-eastern coastal region of China, as one of the most...conference paper 2011

Guo, Y. (author), Zhang, L. (author), Zhang, J. (author)This paper reports the results from a turbulent numerical modelling study on the free overfall in a rectangular channel. A wide range of model parameters (i.e. discrete square bar bed roughness, channel slope, and incoming upstream Froude number) is investigated. The water surface profiles, velocity fields and end-depth are simulated and...conference paper 2006

Guo, J. (author), Nikou, S. (author), Bouwman, W.A.G.A. (author)The increasing number of smart phones presents a significant opportunity for the development of m-payment services. Despite the predicted success of m-payment, the market remains immature in most countries. This can be explained by the lack of agreement on standards and business models for all stakeholders in m-payment ecosystem. In this paper,...conference paper 2013
