Yu, G. (author)Creating a gas-liquid foam means dispersing gas as individual bubbles in an aqueous solution, in which each gas bubble is separated by liquid films or lamella. The most common form of liquid foam (as opposed to solid foams, like polymer sponges) seen in day-to-day life is bulk foam. This refers to a foam that rests in a large container (or flows...doctoral thesis 2021

Gao, P. (author), Wei, J.X. (author), Yu, Q.J. (author)Chemical shrinkage is one of the main reasons leading to the early age deformation of concrete. Hence, the prediction of chemical shrinkage is an important issue for evaluating the deformation of concrete and its influence on the durability of concrete structures. There is still room to improve the accuracy for predicting the chemical shrinkage...conference paper 2021

Yu, J. (author)Memristive devices are promising candidates as a complement to CMOS devices. These devices come with several advantages such as non-volatility, high density, good scalability, and CMOS compatibility. They enable in-memory computing paradigms since they can be used for both storing and computing. However, building in-memory computing systems...doctoral thesis 2021

Yu, C. (author), Pont, S.C. (author)In natural scenes, the wavelength-dependent sunlight scattering in the atmosphere and the presence of occluders and mutual reflections cause variations in the local illumination's magnitude, direction, and spectral composition as a function of time and space. Yet, unlike the characterization of temporal changes of natural light, these spatial...conference paper 2021

Cai, Yuxin (author), Liu, Qing feng (author), Yu, Linwen (author), Meng, Zhaozheng (author), Hu, Zhe (author), Yuan, Qiang (author), Šavija, B. (author)Fresh concrete needs vibration to compact, fill the mould and reach a dense state. During the compaction process, coarse aggregates (CAs) tend to settle, affecting the homogeneity and eventually the long-term durability of hardened concrete. In this study, a 3-D, multi-phase numerical model for fresh concrete is developed for better...journal article 2021

Yu, W. (author), Kleijn, W.B. (author)We describe a new method to estimate the geometry of a room and reflection coefficients given room impulse responses. The method utilizes convolutional neural networks to estimate the room geometry and multilayer perceptrons to estimate the reflection coefficients. The mean square error is used as the loss function. In contrast to existing...journal article 2021

Lv, Maolong (author), Yu, Wenwu (author), Baldi, S. (author)This paper proposes a novel set-invariance adaptive dynamic surface control (DSC) design for a larger class of uncertain large-scale nonlinear input-saturated systems. The peculiarity of this class is that no a priori bound on the continuous control gain functions is assumed (i.e., their boundedness cannot be assumed before obtaining system...journal article 2021
