Chang, L. (author), Rots, J.G. (author), Esposito, R. (author)Perforated unreinforced masonry (URM) walls in out-of-plane (OOP) two-way bending are commonly encountered in natural hazard investigations. However, related research is rather limited. This study focuses on the influence of openings on the two-way bending capacity of URM walls. An experimental database about the perforated URM walls in OOP...journal article 2022

Chang, Brian (author), Yang, Liufei (author), Sensi, M. (author), Achterberg, M.A. (author), Wang, F. (author), Rinaldi, M. (author), Van Mieghem, P.F.A. (author)We introduce a Markov Modulated Process (MMP) to describe human mobility. We represent the mobility process as a time-varying graph, where a link specifies a connection between two nodes (humans) at any discrete time step. Each state of the Markov chain encodes a certain modification to the original graph. We show that our MMP model...conference paper 2022

Chang, X. (author)In reality, the interaction between surface wave-current flow and numerous kinds of man-made maritime structures is local but embedded in a domain with the size of a sea. Detailed simulations of the vast domain are computationally unfeasible. Therefore, articial boundaries are introduced to truncate the large domain so as to obtain a small...doctoral thesis 2021
