Zhu, C. (author), Guo, L (author), Tian, B. (author), He, Q (author), Wang, Zhengbing (author)Estuarine morphodynamics undergo significant changes due to declined sediment supply from river, rising sea-level, and human interferences (Syvitski and Saito, 2007; Syvitski et al., 2009). The Yangtze Estuary is such a case whose decadal morphodynamic evolution was broadly examined. It was documented that the subaqueous delta shifted from...abstract 2017

Guo, L (author), Zhu, C. (author), He, Q (author)Sediment transport provides a critical bridge between hydrodynamics and morphodynamics. Sediment transport behaviour has obvious impacts on morphodynamic development. Long-term morphodynamic modelling enables examination of large scale morphological patterns, such as channel-shoal patterns in estuaries and deltaic channel structures. Non...abstract 2017

Deng, Z. (author), He, Q (author), Chassagne, C. (author), Winterwerp, J.C. (author)The flocculation process and modelling of suspended sediment transport in estuarine regions is a hot topic in estuarine science[Winterwerp, 1999]. The flocculation is greatly influenced by biochemical parameters[De Lucas Pardo, 2014]. In this paper, we analyse the impact of algae on the processes of flocculation in the Yangtze Estuary, and we...abstract 2017

He, S. (author), Qian, QK (author), de Vries, G. (author)In the built environment sector, enhancing energy efficiency through energy retrofitting is a key strategy to mitigate climate change. Despite the efforts made by local municipalities to offer technical and financial support, the rate of home energy retrofit remains low. The decision to undertake home energy retrofit is complex for homeowners....abstract 2023

He, S. (author), Liang, M. (author), Yang, En-hua (author), Schlangen, E. (author)The properties of the interfacial transition zone (ITZ) between microfiber and cement-based matrix are of primary significance for the overall behavior of strain hardening cementitious composites (SHCCs). However, due to the relatively small diameter of polymeric microfibers (e.g., PVA fiber), it is technically difficult to obtain...book chapter 2023

Stroeven, P. (author), He, H. (author)Loose random and dense random mono-size pacl<ing states were investigated by the discrete element modelling (DEM) for eight types of polyhedral grains, for ellipses with different aspect ratio, for cubes and for spheres. Focus was on density, sphericity of the grains and average value and frequency distribution of coordination number. The 3D...conference paper 2013

Ishihara, R. (author), Chen, T. (author), Van der Zwan, M. (author), He, M. (author), Schellevis, H. (author), Beenakker, K. (author)Existent flat-panel display is mechanically stiff because it requires external connection of IC chips. At its present stage, displays with a-Si, metal oxide semiconductor or organic TFTs require still external connection of data driver and controllers, because of their low carrier mobilities. We will review our recent progress on direct...conference paper 2011

Stroeven, P. (author), He, H. (author), Le, L.B.N. (author)Realistic simulation of particulate materials like concrete on meso- as well as micro-level is nowadays possible by fast developments in computer technology. This would be a more economic way than by physical experiinents, which are more time-consuming, laborious and thus expensive. This concern the production of the aggregate structure or of...conference paper 2012

He, J. (author), Suau, M. (author), Baier, Hendrik (author), Kaisers, Michael (author), Oliehoek, F.A. (author)How can we plan efficiently in a large and complex environment when the time budget is limited? Given the original simulator of the environment, which may be computationally very demanding, we propose to learn online an approximate but much faster simulator that improves over time. To plan reliably and efficiently while the approximate simulator...conference paper 2022

(author)Learning effective policies for real-world problems is still an open challenge for the field of reinforcement learning (RL). The main limitation being the amount of data needed and the pace at which that data can be obtained. In this paper, we study how to build lightweight simulators of complicated systems that can run sufficiently fast for...conference paper 2022

Sun, P. (author), Van Mieghem, P.F.A. (author), Kooij, Robert (author), He, Z. (author), Van Mieghem, Piet (author)In this paper, we propose closed-form analytic approximations for the minimum number of driver nodes needed to fully control networks, where links are removed according to both random and targeted attacks. Our approximations rely on the concept of critical links. A link is called critical if its removal increases the required number of driver...conference paper 2019

Suau, M. (author), He, J. (author), Çelikok, Mustafa Mert (author), Spaan, M.T.J. (author), Oliehoek, F.A. (author)Due to its high sample complexity, simulation is, as of today, critical for the successful application of reinforcement learning. Many real-world problems, however, exhibit overly complex dynamics, which makes their full-scale simulation computationally slow. In this paper, we show how to factorize large networked systems of many agents into...conference paper 2022

(author), Whiteson, Shimon (author)We present Multitask Soft Option Learning (MSOL), a hierarchical multitask framework based on Planning as Inference. MSOL extends the concept of options, using separate variational posteriors for each task, regularized by a shared prior. This “soft” version of options avoids several instabilities during training in a multitask setting, and...conference paper 2020
