Li, Mingqi (author), Chen, Huisu (author), Lin, Jianjun (author)Porous networks provide the main transport channels to the active media, which will damage the microstructure and then lead to a subsequent reduction in the strength, serviceability and aesthetic of porous materials. The connectivity of the porous network plays an essential role in the transport properties of these active media. In statistic...conference paper 2021

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

Li, J. (author), Van Zuylen, H.J. (author), Wei, G. (author)Traffic volume and queue length are two important variables to identify traffic states in urban areas. Loop detectors are often used for monitoring traffic. A prominent weakness of loop detector data is the limited reliability due to equipment malfunctions and communication faults. This paper presents a method to identify the validity of loop...conference paper 2014

Bargiacchi, E. (author), Verschoor, C.R. (author), Li, G. (author), Roijers, D.M. (author)Decision-theoretic control of multiple units in game AI [3, 5] is a notoriously hard problem, because the size of the state and action spaces are exponential in the number of agents, making it an interesting testbed for decision theoretic learning algorithms. There are two main approaches: a centralized and decentralized approach. In the...conference paper 2013

Li, D. (author), Daamen, W. (author), Goverde, R.M.P. (author)Train dwell time is one of the most unpredictable components of railway operations mainly due to the varying volumes of alighting and boarding passengers. For reliable estimations of train running times and route conflicts on main lines it is however necessary to obtain accurate estimations of dwell times at the intermediate stops on the main...conference paper 2015

Lundberg, A.B. (author), Li, Y. (author)A full geotechnical risk analysis includes site investigation, model simplification and analysis. The site characterization forms the basis for the choice of the soil parameters used in the subsequent analysis, but the soil data is normally analyzed with crude methods that do not include the effect of the soil variability. A case study is here...conference paper 2015

Ying, Shen (author), Xu, Yifan (author), Li, Chengpeng (author), Guo, Ren Zhong (author), Li, Lin (author)An Easement is a kind of usufructuary right, and its main purpose is that one party wants to use the property of others to improve the benefits and interests of his own real estate. With increasing population and accelerating urbanization, the limitation of urban space has gradually become prominent problem. To use the spatial resources fully,...conference paper 2019

Each institution specifies a set of norms covering a specific aspect of the problem domain with a governance scope defining its remit. Together, they govern the participants and reflect the objectives of the organization. With actors...conference paper 2013
