Karbasizadeh, Nima (author), Hassan HosseinNia, S. (author)According to the well-known loop-shaping control design approach, the steady-state precision of control systems can be improved by stacking integrators. However, due to the waterbed effect in linear control systems, such an action will worsen the transient response by increasing overshoot and creating wind-up problems. This paper presents a new...conference paper 2022

Wan, Z. (author), Xu, Y. (author), Zhang, Y. (author), He, S. (author), Šavija, B. (author)Cracking is one of the main causes for deterioration of concrete structures. Self-healing concrete with 3D-printed vascular networks has excellent potential for autonomous self-healing. This approach is scarcely investigated: no studies have been devoted to the influence of printing parameters on the properties of vascular based self-healing...journal article 2022

Jamalinia, E. (author), Sadeghi Tehrani, F. (author), Steele-Dunne, S.C. (author), Vardon, P.J. (author)Climatic conditions and vegetation cover influence water flux in a dike, and potentially the dike stability. A comprehensive numerical simulation is computationally too expensive to be used for the near real-time analysis of a dike network. Therefore, this study investigates a random forest (RF) regressor to build a data-driven surrogate for a...journal article 2021

(author), Wu, Weiguo (author), Guan, Zhongwei (author)Test on a small scaled model is an effective approach to predict the dynamic response of full scale structure under blast loadings. However, the geometric dimensions of specimens cannot simply comply with complete geometrical similarity due to manufacture or test restrictions. It would result in the difference structural performance between...journal article 2021

Zuo, Y. (author), Qian, Zhiwei (author), Garboczi, Edward J. (author), Ye, G. (author)Many particle-based numerical models have been used to simulate the hydration process of cementitious materials. Most of those models employ regular shape particles, like the commonly used spheres, to represent cement, slag, or fly ash, which neglects the influence of particle shape. To deal with this issue, this study extended the Anm material...journal article 2018
