Ahmad, J.I. (author), Giorgi, Sara (author), Zlatanovic, L. (author), Liu, G. (author), van der Hoek, J.P. (author)Drinking water distribution networks (DWDNs) have a huge potential for cold thermal energy recovery (TED). TED can provide cooling for buildings and spaces with high cooling requirements as an alternative for traditional cooling, reduce usage of electricity or fossil fuel, and thus TED helps reduce greenhouse gas (GHG) emissions. There is no...journal article 2021

Zhang, Xinyue (author), Le, Yun (author), Liu, Y. (author), Liu, Mingqiang (author)In infrastructure project practice, balancing and maximizing the combined effect of exploratory and exploitative innovation have attracted increasing attention, but it is still unclear how to foster ambidextrous innovation in infrastructure projects. To address this gap, we draw on the differentiation-integration framework of ambidexterity...journal article 2021

Zhu, Yonghan (author), Janssen, M.F.W.H.A. (author), Wang, Rui (author), Liu, Yang (author)The global spread of COVID-19 has caused a huge number of confirmed cases and deaths, which in return leads to a plethora of mental disorders across the world. In order to address citizens’ psychological problems, government agencies in many countries have employed AI-based chatbots to provide mental health services. However, there is a...journal article 2021

Liu, S. (author), Zhou, Yangxiao (author), Xie, Mingzhao (author), McClain, M.E. (author), Wang, Xu Sheng (author)A coupled regional and local model is required when groundwater flow and solute transport are to be simulated in local areas of interest with a finer grid while regional aquifer boundary and major stresses should be retained with a coarser grid. The coupled model should also maintain interactions between the regional and local flow systems. In...journal article 2021

Liu, M. (author), Zhao, J. (author), Hoogendoorn, S.P. (author), Wang, M. (author)An integrated approach for optimising traffic signals and cooperative vehicle trajectories at urban intersections is proposed. The upper layer determines the optimal signals using enumeration and the lower layer optimises trajectories under each feasible signal plan. In the lower layer, platoon accelerations are optimised considering comfort...journal article 2021

Liu, J. (author), Draganov, D.S. (author), Ghose, R. (author), Bourgeois, Q. (author)Detecting small-size objects is a primary challenge at archaeological sites due to the high degree of heterogeneity present in the near surface. Although high-resolution reflection seismic imaging often delivers the target resolution of the subsurface in different near-surface settings, the standard processing for obtaining an image of the...journal article 2021

Simhachalam, V. (author), Wang, T. (author), Liu, Y. (author), Wamelink, J.W.F. (author), Montenegro, Lorena (author), Van Gorp, Geert (author)The Paris Agreement requires building retrofitting practices to be more efficient and effective. However, the current practice for building energy retrofitting is lacking behind, and one reason for that is the time-consuming process of energy credit evaluation. Energy performance assessment such as BREEAM-NL in the Netherlands could apply a more...journal article 2021

Liu, Q. (author), Van Mieghem, P.F.A. (author)To shed light on the disease localization phenomenon, we study a bursty susceptible-infected-susceptible (SIS) model and analyze the model under the mean-field approximation. In the bursty SIS model, the infected nodes infect all their neighbors periodically, and the near-threshold steady-state prevalence is non-constant and maximized by a...journal article 2018

Xing, Chao (author), Liu, X. (author), Anupam, K. (author)Traditional sandy soil stabilizers such as lime cement, fly ash and bituminous materials, etc., usually require long curing time. Hence now a day, polymer stabilizer is used more extensively because of its stable chemical property and shorter curing time. For the developing organization, it is important to judge the performance of stabilized...journal article 2018
