Yu, Z. (author), Ye, G. (author), Van Breugel, K. (author), Chen, W. (author)Deterioration of microstructure in cement concrete will cause changes in the transport properties of the concrete. Transport properties at different ages of the concrete provide information about the microstructural changes of the material. A way to measure the transport properties, i.e. the chloride diffusion coefficient, in the laboratory is...conference paper 2014

Yu, Haoyuan (author), Zhang, Hanwen (author), Wang, Yanbo (author), Qin, Z. (author), Chen, Zhe (author), Bauer, P. (author)This article investigates the stability of triple active bridge (TAB) converter with different types of loads. In this paper, port2 of TAB converter adopts voltage control to supply a constant power load (CPL), and port3 uses voltage control to supply a resistor or uses current control to supply a battery.

Yu, C. (author), Chen, Jie (author), Ljung, Lennart (author), Verhaegen, M.H.G. (author)The continuous-time subspace identification using state-variable filtering has been investigated for a long time. Due to the simple orthogonal basis functions that were adopted by the existing methods, the identification performance is quite sensitive to the selection of the system-dynamic parameter associated with an orthogonal basis. To...conference paper 2017

Yu, Q. (author), Chen, Y. (author), Liu, Z. (author), Van de Giesen, N.C. (author), Zhu, D. (author)Algal blooms have been frequently found at the upper reaches of the Tanglang River, which is downstream from the eutrophic Dianchi Lake. The eutrophic lake upstream is considered to be a potential source of phytoplankton, which contributes to the development of harmful algal blooms in the river downstream and can cause many serious problems for...journal article 2015

Liu, Di (author), Baldi, S. (author), Yu, Wenwu (author), Chen, C. L.P. (author)The broad learning system (BLS) paradigm has recently emerged as a computationally efficient approach to supervised learning. Its efficiency arises from a learning mechanism based on the method of least-squares. However, the need for storing and inverting large matrices can put the efficiency of such mechanism at risk in big-data scenarios....journal article 2022

Lu, Peifen (author), Baldi, S. (author), Chen, Guanrong (author), Yu, Wenwu (author)This brief proposes a neuro-adaptive method for the unsolved problem of cooperative tracking rendezvous of nonholonomic mobile robots (NMRs) subject to uncertain and unmodelled dynamics. A hierarchical cooperative control framework is proposed, which consists of a novel distributed estimator along with local neuro-adaptive tracking...journal article 2020

Li, Jinmei (author), Zhang, Shuting (author), Guo, Lizheng (author), Chen, L. (author), Yu, Zhisheng (author)The generation and dissemination of antibiotic resistance bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment has become a critical risk to human health. This study is based on a pilot-scale simulated water distribution system to understand the effects of chlorine disinfection treatment (without free chlorine) on ARB and...journal article 2021

Li, Changzhen (author), Yu, Junyi (author), Xue, J. (author), Chen, Wei (author), Wang, Shoufeng (author), Yang, Kun (author)For a long time, the development of maritime communication has been restricted by the low data rate, high-latency and high cost of the current communication systems. The upgrade of new generation mobile communication technologies is attracting more and more attention to conduct a shore-based broadband mobile communication network with high...journal article 2021

Chen, Cong (author), Batselier, K. (author), Yu, Wenjian (author), Wong, Ngai (author)Tensor, a multi-dimensional data structure, has been exploited recently in the machine learning community. Traditional machine learning approaches are vector- or matrix-based, and cannot handle tensorial data directly. In this paper, we propose a tensor train (TT)-based kernel technique for the first time, and apply it to the conventional...journal article 2022

(author)Audio magnetotelluric (AMT) is commonly used in mineral resource exploration. However, the weak energy of AMT signals makes them susceptible to being overwhelmed by noise, leading to erroneous geophysical interpretations. In recent years, deep learning has been applied to AMT denoising and has shown better denoising performance compared to...journal article 2024

(author)Nanomagnets are widely used to store information in non-volatile spintronic devices. Spin waves can transfer information with low-power consumption as their propagations are independent of charge transport. However, to dynamically couple two distant nanomagnets via spin waves remains a major challenge for magnonics. Here we experimentally...journal article 2020
