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

Yu, Changbin (author), Li, Lin (author), Ying, Shen (author), He, Biao (author), Zhao, Zhigang (author), Wan, Yuan (author)When the land use pattern changes from an extensive way to an intensive way, the development of 3D land-use has become reality. Due to the vertical heterogeneity of property rights, establishment of 3D cadastre is imperative. Meanwhile, registration and certification of the property rights have become important approaches to serve public and...conference paper 2012

Guo, Renzhong (author), Yu, Changbin (author), He, Biao (author), Zhao, Zhigang (author), Li, Lin (author), Ying, Shen (author)The establishment of 3D cadastre is imperative and needs support from legal, organizational and technological aspects. In Shenzhen, China, establishment of 3D cadastre has achievedgreat progress. The joint register mechanism was employedfirstly in Shenzhen, and related research is going on, including definitions, visualization and topological...conference paper 2012

Zhao, Zhigang (author), Guo, Renzhong (author), Li, Lin (author), Ying, Shen (author)With the accelerated urbanization process, the trend of three-dimensional land use makes the traditional model of 2D cadastral management encounter challenges, because of insufficiency to express in 3D. Therefore, the 3D cadastre and related concepts have been proposed. The breadth and depth of its research are gradually broadened and refined....conference paper 2012

Tobón, L. (author), Chen, J. (author), Lee, J. (author), Yuan, M. (author), Zhao, B. (author), Liu, Q.H. (author)Many system-level electromagnetic design problems are multiscale and very challenging to solve. They remain a significant barrier to system design optimization for a foreseeable future. Such multiscale problems often contain three electrical scales, i.e., the fine scale (geometrical feature size much smaller than a wavelength), the coarse scale ...conference paper 2013

Zhao, W. (author), Bou Ammar, H. (author), Roos, N. (author)In this paper a novel framework capable of both accurate predictions and classifications of dynamic images is introduced. The proposed technique makes of use of a novel combination of sparse coding, a feature extraction algorithm, and three-way weight tensor conditional restricted Boltzmann machines, a form of deep learning. Experiments...conference paper 2013

Guo, Renzhong (author), Luo, Feng (author), Zhao, Zhigang (author), He, Biao (author), Li, Lin (author), Luo, Ping (author), Ying, Shen (author)As the economy and urbanization develop, the expansion of the city not only develops towards the horizontal space, but also towards the vertical space. Facing the development of three-dimensional (3D) space, the traditional two-dimensional (2D) cadastral management mode cannot satisfy the need of current 3D land use and urban plan, so developing...conference paper 2014

We investigated the rotation of non-spherical particles (rod-like and disk-like) in turbulent channel flow with focus on inertial effects. A direct numerical simulation (DNS) with an Eulerian-Lagrangian approach was performed. A wide range of particle aspect ratios, λ, ranging from 0.01 to 50 were considered for Stokes numbers St equal to 1 and...conference paper 2015

A suspension of oblate spheroidal (disk-like) particles in turbulent channel flow has been investigated with focus on the translational and rotational particle statistics. The effects of particle aspect ratio and inertia have been explored. The disk-like particles exhibited a significant preferential orientation in the plane of the mean shear....conference paper 2015

Ying, Shen (author), Guo, Renzhong (author), Li, Weiyang (author), Yang, Jie (author), Zhao, Zhigang (author), Li, Lin (author)There are many 3D objects with denser aggregation that they are fully/partly coherent touched with each other through shared facets, which we called coherent set of 3D objects. Visualization for 3D property unit is an effective way to understand 3D spatial occupation, location and relationship in urban space, particularly in the coherent set of...conference paper 2016

Cazacliu, B. (author), Moreno-Juez, J. (author), Zhao, L.J. (author)There have been a great number of laboratory studies on mixing approach for recycled aggregate concrete (RAC) even if in practice, the simplest procedures are generally employed. Some of these methods give good results comparing with the traditional mixing method. The present paper resume some main mixing methods proposed in the literature,...conference paper 2017

Zhao, Zengfeng (author), Courard, Luc (author), Michel, Frédéric (author), Remond, Sébastien (author), Damidot, Denis (author)Large amounts of construction and demolition wastes (C&DW) especially concrete wastes are generated annually and will increase in the future. Until now, only a small fraction of concrete wastes is re-used as recycled concrete aggregates (RCA) in the manufacture of concrete. In this paper, the feasibility of using RCA obtained from old concrete...conference paper 2017

Zhao, Lixiao (author), Feng, Pan (author)Chloride diffusion in concrete is one of the key parameters of durability design for structure. Existing methods of reducing the chloride diffusion such as decreasing water-cement ratio and adding mineral admixtures often lead to increase the risk of concrete cracking. In this study, we focused on mitigating the permeation of chloride ions in...conference paper 2021

Zhao, Shengying (author), Guan, Xinchun (author), Qiao, Guofu (author)Superabsorbent polymer (SAP) can modify the microstructure and influence the mechanical properties of cement paste in at least two ways: while cavities left by SAP increase the total porosity, water released by SAP affects the hydration degree of the surrounding paste. As a starting point for investigation into the overall effect, this study...conference paper 2021
