Tian, Zhan (author), Yu, Ziwei (author), Li, Yifan (author), Ke, Q. (author), Liu, Junguo (author), Luo, Hongyan (author), Tang, Yingdong (author)Climate change and rapid urbanization have made it difficult to predict the risk of pollution in cities under different types of rainfall. In this study, a data-driven approach to quantify the effects of rainfall characteristics on river pollution was proposed and applied in a case study of Shiyan River, Shenzhen, China. The results indicate...journal article 2022

Haringa, C. (author), Tang, W. (author), Noorman, H.J. (author)The compartment model (CM) is a well-known approach for computationally affordable, spatially resolved hydrodynamic modeling of unit operations. Recent implementations use flow profiles based on Computational Fluid Dynamics (CFD) simulations, and several authors included microbial kinetics to simulate gradients in bioreactors. However, these...journal article 2022

Tang, Jinyu (author), Castaneda, Pablo (author), Marchesin, Dan (author), Rossen, W.R. (author)Foam is remarkably effective in the mobility control of gas injection for enhanced oil recovery (EOR) processes and CO<sub>2</sub> sequestration. Our goal is to better understand immiscible three-phase foam displacement with oil in porous media. In particular, we investigate (i) the displacement as a function of initial (I) and injection (J)...conference paper 2022

Tang, Shi Yuan (author), Oliehoek, F.A. (author), Irissappane, Athirai A. (author), Zhang, Jie (author)Cross-Entropy Method (CEM) is a gradient-free direct policy search method, which has greater stability and is insensitive to hyperparameter tuning. CEM bears similarity to population-based evolutionary methods, but, rather than using a population it uses a distribution over candidate solutions (policies in our case). Usually, a natural...conference paper 2021

Xu, J. (author), Soeiro, Thiago B. (author), Gao, Fei (author), Tang, Houjun (author), Bauer, P. (author)Three-legs active power decoupling (APD) converters are widely studied in the single-phase grid-connected systems to enhance the circuit lifetime by creating an alternative path for the typical existing dc-side power pulsating ripple. Therefore, this reduces the requirement of smoothing dc capacitors allowing compact designs even with the...journal article 2021

Liu, Zhihui (author), Wang, Li (author), Kong, Fanlei (author), Huang, Xia (author), Tang, Zhi (author), He, Shi (author), Vink, P. (author)BACKGROUND: Many occupations require workers to stand for prolonged periods, which can cause discomfort, pain and even injures. Some supermarkets in life provide a foot pad for checkout staff to let them stand on it at work, thereby reducing standing fatigue caused by standing for a long time. The inclined platform is the same as the foot pad...journal article 2021

Cassottana, Beatrice (author), Aydin, N.Y. (author), Tang, Loon Ching (author)The resilience of water distribution systems (WDSs) has gained increasing attention in recent years. Various performance loss and recovery behaviors have been observed for WDSs subject to disruptions. However, a model for their characterization, which could provide further insight for resilience assessment and enhancement, is still lacking....journal article 2021

Tang, T. (author), Ghorbani, Amineh (author), Chorus, C.G. (author)In the field of opinion dynamics, the hiding of opinions is routinely modeled as staying silent. However, staying silent is not always feasible. In situations where opinions are indirectly expressed by one’s observable actions, people may however try to hide their opinions via a more complex and intelligent strategy called obfuscation, which...journal article 2021
