Tian, Cong (author), Wei, Xiaosheng (author)An improved method based on the ring test called eccentric ring test is used to study the cracking of cementitious materials. The water-cement ratios were 0.25, 0.30, 0.35, 0.4 and the aggregate mass fractions were 10%, 30%, 50%, respectively. It was found that with the increase of water-cement ratio and aggregate, the cracking time of the...conference paper 2021

Compressible Rayleigh-Taylor turbulent mixing (CRTM) induced by Rayleigh-Taylor instability occurs when a compressible fluid of heavy density is accelerated or supported against gravity by a compressible fluid of light density, and is of fundamental importance in applications from combustion, to inertial confinement fusion, and to astrophysics....conference paper 2015

Tian, H.Y. (author), Cai, H.M. (author), Xu, X. (author), Lai, J.H. (author)Removing noise effectively without destroying important fine structure is a challenging problem in image processing. Among many techniques, diffusion method is shown to be attractive due to its rigorous mathematical background and efficiency. In this paper we propose a well-balanced diffusion method by redefining the diffusion and regularization...conference paper 2011

Li, J. (author), Tian, Y. (author), Cassidy, M.J. (author)Natural soil is one of the most variable materials as a result of physical and chemical changes. The variation in soil properties significantly affects the failure mechanism and bearing capacity of a footing. This effect is further complicated by considering the spatial correlation of the soil properties. The purpose of this study is to...conference paper
