Liu, Qingxin (author)Most injuries in football occur in the lower extremities due to high muscle stress. To prevent such injuries, the Dutch Football Association (KNVB) and the Delft University of Technology developed the Smart Sensor Shorts, an inertial sensor-based tracking system measuring the athlete’s lower body kinematics, to improve physical load estimates...master thesis 2023

Zhang, Y. (author), Zhang, Shizhe (author), Liu, C. (author), Copuroglu, Oguzhan (author)In this paper, the authors characterized two types of zonation within slag rims in aged alkali-activated slag (AAS) systems through SEM and TEM technology. These two elemental zonation were closely related to the pore structure of AAS pastes, thus providing strong implication for the transport- and durability-related performance of AAS...journal article 2023

Liu, C. (author), Liang, X. (author), Chen, Y. (author), Li, Z. (author), Ye, G. (author)In this study, the impacts of tap water immersion on the pore solution, phase assemblages, gel chemistry and structure, and pore structure of alkali-activated slag (AAS) pastes were studied. AAS degrades under such condition and the potential mechanisms can be concluded as lower reaction rates, gel decomposition and carbonation. The leaching...journal article 2023

Yang, Jun (author), Paragi, Zsolt (author), Frey, Sándor (author), Gurvits, L. (author), Liao, Mai (author), Liu, Xiang (author), Cui, Lang (author), Yang, Xiaolong (author), Chen, Wen (author)Dwarf galaxies are characterized by a very low luminosity and low mass. Because of significant accretion and ejection activity of massive black holes, some dwarf galaxies also host low-luminosity active galactic nuclei (AGNs). In a few dwarf AGNs, very long baseline interferometry (VLBI) observations have found faint non-thermal radio...journal article 2023

Golchin, A. (author), Guo, Y. (author), Vardon, P.J. (author), Liu, S. (author), Zhang, G. (author), Hicks, M.A. (author)The coupling effect of initial shear stress and thermal cycles on the thermomechanical behaviour of clay concrete and sand-concrete interfaces has been studied. A set of drained monotonic direct shear tests was conducted at the soil-concrete interface level. Samples were initially sheared to half of the material's shear strength and then they...journal article 2023

Li, Z. (author), Liang, X. (author), Liu, C. (author), Liang, M. (author), van Breugel, K. (author), Ye, G. (author)This study investigates the deformation of free and stress of restrained alkali-activated slag concrete (AASC), respectively, under semi-adiabatic condition. The concrete shows first thermal expansion, which is compensated soon by autogenous shrinkage. The subsequent cooling down of the concrete aggravates shrinkage and development of tensile...journal article 2022

Sun, Yubo (author), Liu, Zhiyuan (author), Ghorbani, Saeid (author), Ye, G. (author), De Schutter, Geert (author)The present study explores the possibility of replacing blast furnace slag (BFS) with coal fly ash (FA) to produce alkali-activated material (AAM) concrete with hybrid precursors. With an increased FA replacement ratio, the reaction kinetics, fresh and hardened properties of AAM mixtures have been investigated. The retardation effect on the...journal article 2022

Ninan, Dr Johan (author), Hertogh, M.J.C.M. (author), Liu, Yan (author)Infrastructure projects are costly, colossal, complex, captivating, controversial, and laden with control issues. The development of these projects causes environmental, social, and political disruptions in the local environment, which have to be carefully handled by professionals in the field. This article aims to enhance the performance of...journal article 2022

Li, J. (author), Zhou, Yangxiao (author), Wang, Wenke (author), Liu, S. (author), Li, Ying (author), Wu, Ping (author)The sustainable development of groundwater resources in arid and semi-arid regions is a challenging task hindered by climate change and human activities. The rational utilization and management of groundwater resources is, therefore, dependent on an understanding of the influences of human and climatic factors on the spatial distribution of...journal article 2022

(author)Supplementary control (SC) technology is widely leveraged by power supply companies in active distribution networks (ADNs) to improve their stability and dynamic characteristics. Yet, the existed SCs are generally implemented from inside the converter controllers of distributed generators (DGs) or active loads, so there is a need to redesign...journal article 2022
