Sun, Yubo (author), Mohan, Manu K. (author), Dai, Xiaodi (author), Zhang, Yiyuan (author), Ye, G. (author), De Schutter, Geert (author)The proper control of the rheological performance of silicate-based alkali-activated slag (AAS) mixtures is problematic, as the conventional superplasticizers become less effective in alkaline media. Nevertheless, several methods have been proposed to improve the workability of silicate-activated AAS, such as by extending the mixing time, and...journal article 2024

Jamshidnejad, A. (author), Sun, D. (author), Ferrara, Antonella (author), De Schutter, B.H.K. (author)Model predictive control (MPC) has been widely used for traffic management, such as for minimizing the total time spent or the total emissions of vehicles. When long-term green urban mobility is considered including e.g. a constraint on the total yearly emissions, the optimization horizon of the MPC problem is significantly larger than the...journal article 2023

Sun, Y. (author), Ditmar, P.G. (author), Riva, R.E.M. (author)In this study, we develop a methodology to estimate monthly variations in degree-1 andC<sub>20</sub> coefficients by combing Gravity Recovery and Climate Experiment (GRACE) data withoceanic mass anomalies (combination approach).With respect to the method by Swenson et al.,the proposed approach exploits noise covariance information of both...journal article 2017

Yang, D. (author), Sun, Y (author), Di Stefano, D. (author), Turrin, M. (author), Sariyildiz, I.S. (author)Surrogate-based Optimization is a useful approach when the objective function is computationally expensive to evaluate, compared to Simulation-based Optimization. In the surrogate-based method, analytically tractable “surrogate models” (also known as “Response Surface Models — RSMs” or “metamodels”), are constructed and validated for each...conference paper 2016

Sun, J. (author)Nitrogen dioxide (NO2) is one of the nitrogen oxides (NOx) pollutants. Not only the NO2 itself is toxic to human health, but also the precursors of a number of hazardous secondary air pollutants, such as nitric acid, tropospheric ozone and nitrate component of particulate matters. Besides, NO2 is also an essential substances involving in ozone...master thesis 2016
