Schreyers, Louise J. (author), Van Emmerik, Tim H.M. (author), Bui, Thanh-Khiet L. (author), van Thi, Khoa L. (author), Vermeulen, Bart (author), Nguyen, Hong-Q. (author), Wallerstein, Nicholas (author), Uijlenhoet, R. (author), van der Ploeg, Martine (author)Plastic is an emerging pollutant, and the quantities in rivers and oceans are expected to increase. Rivers are assumed to transport land-based plastic into the ocean, and the fluvial and marine transport processes have been relatively well studied to date. However, the processes controlling the transport in tidal rivers and estuaries, the...journal article 2024

Nguyen, Hieu Thao (author), Bui, Hoa T. (author), Nguyen, Duy Cuong (author), Verhaegen, M.H.G. (author)Motivated by a number of questions concerning transversality-type properties of pairs of sets recently raised by Ioffe and Kruger, this paper reports several new characterizations of the intrinsic transversality property in Hilbert spaces.

Yuan, Y. (author), Goni Ros, B. (author), Bui, Ha H. (author), Daamen, W. (author), Vu, Hai L. (author), Hoogendoorn, S.P. (author)Macroscopic pedestrian models are theoretically simpler than microscopic models, and they can potentially be solved faster while producing reasonable predictions of crowd dynamics. Therefore, they can be very useful for applications such as large-scale simulation, real-time state estimation and crowd management. However, the numerical methods...journal article 2020
