Feng, Z. (author), Ferrari, Riccardo M.G. (author), van Wingerden, J.W. (author), Liu, Y. (author)Wind turbines may experience local weather perturbation, which is not taken into account by the commonly-used wind turbine simulation packages. Without this information, it is extremely challenging to evaluate the controller performance with regard to the effect of the variation of local atmospheric conditions. On the other side, it is too...conference paper 2023

Feng, W. (author), He, P. (author), Koetsier, M. (author), Pavlovic, M. (author)Wrapped composite joint is an innovative technique which connects steel hollow sections through bonding such that the fatigue performance is improved compared to welded joint. In this paper, a DIC-based method of monitoring surface strains is proposed to quantify the debonding crack propagation within the composite wrap layers during high cycle...conference paper 2022

(author), Chen, Yong (author), Zhao, Bo (author)Body Channel Communication (BCC) offers a low-loss signal transmission medium for ultra-low-power wearable devices on human body [1]. However, the effective communication range on human body is limited to less than 1m in the state-of-the-art BCC transceivers [2], where the signal loss at the interface of body surface and BCC receiver remains to...conference paper 2022

Feng, Z. (author), Gallo, A.J. (author), Liu, Y. (author), Pamososuryo, A.K. (author), Ferrari, Riccardo M.G. (author), van Wingerden, J.W. (author)The current trend in the evolution of wind turbines is to increase their rotor size in order to capture more power. This leads to taller, slender and more flexible towers, which thus experience higher dynamical loads due to the turbine rotation and environmental factors. It is hence compelling to deploy advanced control methods that can...conference paper 2022

Feng, Shuo (author), Jiang, Tao (author), Chen, Wei (author), Fan, Xuejun (author), Zhang, Kouchi (author), Fan, Jiajie (author)As a core packaging material of light color conversion, phosphor/silicone composite plays an indispensable role in light emitting diode (LED) packaging. At present, commercial LED packages mainly use blue LED chips to stimulate Yttrium Aluminum Garnet (YAG) yellow phosphor to reach a white color. However, (Ca,Sr)AlSiN 3 :Eu 2+ (CSASN) red...conference paper 2022

Sun, Zhu (author), Yang, J. (author), Feng, Kaidong (author), Fang, Hui (author), Qu, Xinghua (author), Ong, Yew Soon (author)Product bundling is a commonly-used marketing strategy in both offline retailers and online e-commerce systems. Current research on bundle recommendation is limited by: (1) noisy datasets, where bundles are defined by heuristics, e.g., products co-purchased in the same session; and (2) specific tasks, holding unrealistic assumptions, e.g.,...conference paper 2022

Zhao, Lixiao (author), Feng, Pan (author)Chloride diffusion in concrete is one of the key parameters of durability design for structure. Existing methods of reducing the chloride diffusion such as decreasing water-cement ratio and adding mineral admixtures often lead to increase the risk of concrete cracking. In this study, we focused on mitigating the permeation of chloride ions in...conference paper 2021

Feng, Taotao (author), Jiang, Jinyang (author), Chu, Hongyan (author), Wang, Liguo (author)This paper reports on a study to determine the possibility of using ultra-fine fly ash (UFA) for partial or total replacement of normal fly ash (NFA) in ultra-high performance concrete (UHPC). Workability, microstructure, porosity, drying shrinkage as well as mechanical properties were comprehensively studied to investigate the influence of UFA...conference paper 2021

Ye, Shaoxiong (author), Feng, Pan (author), Liu, Yao (author), Liu, Jiaping (author)The nanoscale dissolution flux of tricalcium aluminate (C3A) in flowing water is characterized in situ by Digital Holographic Microscopy (DHM). The pure dissolution of C3A in flowing water with a flow rate of 34 ml·min-1 before the precipitation of hydrated phases only lasted about one quarter of a second, and the pure dissolution rate mostly...conference paper 2021

Ju, Siyi (author), Feng, Taotao (author), Wang, Liguo (author), Jiang, Jinyang (author)In this paper, four kinds of ecological fine aggregates (manufactured sand, recycled sand, aeolian sand and river sand) were used to prepared UHPC, the effects of the fine aggregates on the workability, rheological properties and mechanical properties of UHPC were studied. The results reveal that the type and content of fine aggregate have an...conference paper 2021

Feng, S. (author), Zelasko, Piotr (author), Moro-Velázquez, Laureano (author), Scharenborg, O.E. (author)This paper tackles automatically discovering phone-like acoustic units (AUD) from unlabeled speech data. Past studies usually proposed single-step approaches. We propose a twostage approach: the first stage learns a subword-discriminative feature representation, and the second stage applies clustering to the learned representation and obtains...conference paper 2021

Feng, S. (author), Scharenborg, O.E. (author)For a language with no transcribed speech available (the zero-resource scenario), conventional acoustic modeling algorithms are not applicable. Recently, zero-resource acoustic modeling has gained much interest. One research problem is unsupervised subword modeling (USM), i.e., learning a feature representation that can distinguish subword units...conference paper 2021

Wang, X. (author), Feng, S. (author), Zhu, Jihua (author), Hasegawa-Johnson, Mark (author), Scharenborg, O.E. (author)This paper proposes a new model, referred to as the show and speak (SAS) model that, for the first time, is able to directly synthesize spoken descriptions of images, bypassing the need for any text or phonemes. The basic structure of SAS is an encoder-decoder architecture that takes an image as input and predicts the spectrogram of speech that...conference paper 2021
