Taal, J.R. (author), Chen, Z. (author), He, Y. (author), Lagendijk, R.I.L. (author)Wireless and Internet video applications are inherently subjected to bit errors and packet errors, respectively. This is especially so if constraints on the end-to-end compression and transmission latencies are imposed. Therefore, it is necessary to develop methods to optimize the video compression parameters and the rate allocation of these...journal article 2004

Ishihara, R. (author), Chen, T. (author), Van der Zwan, M. (author), He, M. (author), Schellevis, H. (author), Beenakker, K. (author)Existent flat-panel display is mechanically stiff because it requires external connection of IC chips. At its present stage, displays with a-Si, metal oxide semiconductor or organic TFTs require still external connection of data driver and controllers, because of their low carrier mobilities. We will review our recent progress on direct...conference paper 2011

He, Y. (author), Chen, J.Y. (author), Knab, J.R. (author), Zheng, W. (author), Markelz, A.G. (author)We investigate the presence of structural collective motions on a picosecond timescale for the heme protein, cytochrome c, as a function of oxidation and hydration, using terahertz (THz) time domain spectroscopy and molecular dynamics simulations. The THz response dramatically increases with oxidation, with the largest increase for lowest...journal article 2011

Xiao, Jing (author), Wei, Qi-Qin (author), Yang, Daoguo (author), Zhang, Ping (author), He, Ning (author), Zhang, Kouchi (author), Ren, Tian-Ling (author), Chen, Xian-Ping (author)The emerging field of nanophotonics requires plasmonic devices to be fully compatible with semiconductor fabrication techniques. However, very few feasible practical structures exist at present. Here, we propose a CMOS-compatible hybrid plasmonic slot waveguide (HPSW) with enhanced field confinement. Our simulation results show that the HPSW...journal article 2016

Xiao, Jing (author), Wei, Qi-Qin (author), Yang, Duo Guo (author), Zhang, Ping (author), He, Ning (author), Zhang, Kouchi (author), Chen, Xian Ping (author)The slot waveguide has attracted considerable attention because of its ability to confine and guide electromagnetic energy at the subwavelength scale beyond the diffraction limit. We propose a novel terahertz slot waveguide structure to achieve a better tradeoff between propagation length and field confinement capacity, the novel waveguide...journal article 2017

He, L. (author), de Weerdt, M.M. (author), Yorke-Smith, N. (author), Liu, Xiaolu (author), Chen, Yingwu (author)Agile Earth observation satellite (AEOS) scheduling is complex, due to long visible time windows and time-dependent transitions between observations. We introduce a generic approach suited for scheduling problems characterised by time-dependency and/or sequence-dependency. Our approach is a novel hybridization of adaptive large neighbourhood...conference paper 2018

Li, Mengxia (author), Mou, Junmin (author), Liu, Rongfang (author), Chen, P. (author), Dong, Zhuojian (author), He, Yixiong (author)Following the growth in global trade activities, vessel traffic has increased dramatically in some busy waterways and ports. However, such increments have made it more complex to manage the regional vessel traffic, which can increase the risk of an accident in the area. To model and analyze the relationship between vessel traffic and maritime...journal article 2019

Chen, Zhuo Yi (author), Li, Chuan Xi (author), He, Jun (author), Xin, H. (author)Diaphragm cutouts are set to release redundant constraints and hence reduce weld fatigue at the connection of U-ribs to diaphragms in orthotropic steel decks. However, most fatigue cracks which originate from the edge of cutouts are in fact detected in the diaphragms. Therefore, a retrofit technology on cracked cutouts at the diaphragm is...journal article 2020

Ko, Ching Yun (author), Chen, Cong (author), He, Zhuolun (author), Zhang, Yuke (author), Batselier, K. (author), Wong, Ngai (author)Sum-product networks (SPNs) constitute an emerging class of neural networks with clear probabilistic semantics and superior inference speed over other graphical models. This brief reveals an important connection between SPNs and tensor trains (TTs), leading to a new canonical form which we call tensor SPNs (tSPNs). Specifically, we...journal article 2020

Xiong, Yongming (author), Li, Chuanxi (author), Chen, Zhuoyi (author), He, Jun (author), Xin, H. (author)Residual stresses change the stress ratio of fluctuating stresses, hence seriously affect the fatigue life of orthotropic steel decks (OSDs) under traffic loading. Residual stress distributions near the U rib-diaphragm joints are very complicated and need to be investigated further. In this paper, a systematic method has been proposed for...journal article 2020

Wang, Jin (author), Han, Hui (author), Li, H. (author), He, Shiming (author), Sharma, Pradip Kumar (author), Chen, Lydia Y. (author)Due to high capacity and fast transmission speed, 5G plays a key role in modern electronic infrastructure. Meanwhile, sparse tensor factorization (STF) is a useful tool for dimension reduction to analyze high-order, high-dimension, and sparse tensor (HOHDST) data, which is transmitted on 5G Internet-of-things (IoT). Hence, HOHDST data relies...journal article 2021
