Sun, Yufeng (author), Pardoen, Benoît (author), van den Eijnden, A.P. (author), Wong, Henry (author)Clay rocks are multiphase porous media having a complex structure and behaviour characterised by heterogeneity, damage and viscosity, existing on a wide range of scales. The mesoscopic scale of mineral inclusions embedded in a clay matrix has an important role in the mechanisms of deformation under mechanical loading by cracking and creeping....journal article 2023

Nijhuis, S. (author), Sun, Yimin (author), Cannatella, D. (author), Xie, G. (author)Adaptive urban transformations employ landscape-based regional design as an integrative and multiscale design and planning approach for sustainable urban development. In this approach, natural and urban dynamics as derived from systems analysis set the pace and nature of adaptation. This chapter presents an initial strategy for adaptive urban...book chapter 2023

Nijhuis, S. (author), Sun, Yimin (author), Lange, Eckart (author)Deltaic areas are amidst the most favourable territories around the globe. Their strategic location and superior quality of their soils are core factors supporting both human development and the rise of these regions as global economic hubs. At the same time, deltas are extremely vulnerable to multiple threats from both climate change and the...book chapter 2023

Sun, Junzi (author), Tassanbi, A. (author), Obojski, Piotrek (author), Plantholt, Philip (author)The increasing demand for global air travel has intensified the urgency to mitigate aviation’s carbon emissions. Continuous monitoring of aircraft fuel efficiency and emissions has become an important task in aviation. One of the main challenges has been the lack of surveillance data for flights across oceans, specifically in the North Atlantic...conference paper 2023

Sun, D. (author), Jamshidnejad, A. (author), De Schutter, B.H.K. (author)Traffic control is essential to reduce congestion in both urban and freeway traffic networks. These control measures include ramp metering and variable speed limits for freeways, and traffic signal control for urban traffic. However, current traffic control methods are either too simple to respond to complex traffic environment, or too...journal article 2023

Wang, Te (author), Li, Zongkun (author), Ge, W. (author), zhang, Z.H. (author), Zhang, Yadong (author), Sun, Heqiang (author), Jiao, Yutie (author)Compared with a single reservoir, the risk in cascade reservoirs has the transmission and superposition effect, which increases the complexity of its risk consequence assessment. In view of this problem, the direct consequence (DC) and potential consequence (PC) were defined as two parts of the dam breach risk consequence of cascade reservoirs....journal article 2023

Yang, M. (author), Sun, H. (author), Geng, S. (author)Recent years have seen the increasing complexity of engineered systems. Complexity and uncertainty also exist in engineered systems’ interactions with human operators, managers, and the organization. Resilience, focusing on a system's ability to anticipate, absorb, adapt to, and recover from disruptive situations, can provide an umbrella concept...journal article 2023

Jeschke, J.M. (author), Sun, D. (author), Jamshidnejad, A. (author), De Schutter, B.H.K. (author)While Model Predictive Control (MPC) is a promising approach for network-wide control of urban traffic, the computational complexity of the, often nonlinear, online optimization procedure is too high for real-time implementations. In order to make MPC computationally efficient, this paper introduces a parameterized MPC (PMPC) approach for...journal article 2023

Hao, R. (author), Zhang, Yuxiao (author), Ma, Wanjing (author), Yu, Chunhui (author), Sun, Tuo (author), van Arem, B. (author)With the development of internet of vehicles and automated driving, individual-based trajectory control at intersections becomes possible. Trajectory planning and coordination for connected and automated vehicles (CAVs) have been studied at isolated “signal-free” intersections and in “signal-free” corridors under the fully CAV environment in...journal article 2023

Gareth (author), Sun, Zhanli (author), Berger, Thomas (author)There has so far been no shared understanding of validity in agent-based simulation. We here conceptualise validation as systematically substantiating the premises on which conclusions from simulation analysis for a particular modelling context are built. Given such a systematic perspective, validity of agent-based models cannot be ensured if...journal article 2023

Zhang, Qunli (author), Zhao, Wenqiang (author), Sun, Donghan (author), Meng, Xiangzhao (author), Hooman, K. (author), Yang, Xiaohu (author)NO<sub>x</sub> emission reduction from gas boilers has become a key issue in improving air quality. Combustion air humidification technology is gradually being used to reduce NO<sub>x</sub> emissions. However, the NO<sub>x</sub> emission reduction effect of gas boilers at a higher combustion air humidity has been studied less. A flue gas with...journal article 2023

Ni, Ying (author), Li, Y. (author), Yuan, Y. (author), Sun, Jian (author)In recent years, the interest in riding in cities using the two-wheeler (e.g., bicycles, electric bicycles, electric mopeds, etc.) increases. Mixed-traffic road segments are one of the most common traffic scenes where the mixed two-wheeler flows exist. Because the movements are often not restricted by lanes, the two-wheeler uses lateral road...journal article 2023
