Wu, W. (author), Liu, Xinwang (author), Zhou, Ligang (author), Qin, Jindong (author), Rezaei, J. (author)Since the development of the best–worst method (BWM) in 2015, it has become a popular research focus in multi-criteria decision-making. The original optimization problem of the BWM is a nonlinear min–max model that can lead to multiple optimal solutions, while the linear model of the BWM produces a unique solution. The two models need to be...journal article 2024

Liu, Q. (author), Ghodrat, Dr. Sepideh (author), Jansen, K.M.B. (author)We developed a shape-changing constructive kit, named Mimosa1. A key component of the toolkit is the modular hinges, each of which is equipped with two antagonistic shape memory alloy (SMA) wires. One wire deforms the hinge to approach its predetermined angle at high temperature, and another wire drives the hinge back when it cools down....conference paper 2024

Liu, Xiaotian (author)In Berlin, the public transportation system is large and varied. Train (S-Bahn), tram, metro (U-Bahn), and bus consist of the main skeleton of the system. However, due to historical reasons, most U-bahn and tram lines are located only in the former West and East Berlin, respectively. Thus, lots of transfer stations are located in the area where...master thesis 2023
