(author), Qu, Huamin (author)Recent attempts at utilizing visual analytics to interpret Recurrent Neural Networks (RNNs) mainly focus on natural language processing (NLP) tasks that take symbolic sequences as input. However, many real-world problems like environment pollution forecasting apply RNNs on sequences of multi-dimensional data where each dimension represents an...conference paper 2020

Sun, Yimin (author), Kim, Young Seo (author), Qu, S. (author), Verschuur, D.J. (author)Joint migration inversion is a recently proposed technology, accommodating velocity model building and seismic migration in one integrated process. Different from the widely accepted full waveform inversion technology, it uses imaging parameters, i.e. velocities and reflectivities of the subsurface, to parameterize its solution space. The...journal article 2020

Qu, Y. (author), Metrikine, A. (author)In this study a new wake oscillator model is proposed to describe the coupled cross-flow and in-line vortex-induced vibrations of an elastically supported rigid cylinder. Different from many other studies where two wake oscillators have been applied, the current model uses only one wake oscillator coupled to both cross-flow and in-line motions....journal article 2020

Qu, Y. (author), Metrikine, A. (author)In this paper, a new wake oscillator model with nonlinear coupling is proposed for the modelling of vortex-induced vibration. The purpose is to develop a model that is capable of reproducing both free and forced vibration experiments. To achieve this goal, an existing van der Pol wake oscillator model is first reviewed. The limitations of the...journal article 2020

Qu, S. (author), Guan, Zhe (author), Verschuur, D.J. (author), Chen, Yangkang (author)Microseismic methods are crucial for real-Time monitoring of the hydraulic fracturing dynamic status during the development of unconventional reservoirs. However, unlike the active-source seismic events, the microseismic events usually have low signal-To-noise ratio (SNR), which makes its data processing challenging. To overcome the noise...journal article 2020

Qu, Y. (author), Metrikine, A. (author)To illustrate the influence of the in-line coupling on the prediction of vortex-induced vibration (VIV), the simulation results of the coupled cross-flow and in-line VIVs of flexible cylinders- obtained with three different wake oscillator models with and without the in-line coupling- are compared and studied in this paper. Both the cases of...journal article 2020

Chen, Y. (author), Qu, L. (author)The rapid development of Chinese megacities in the last decades have been mainly characterized by top-down planning and large-scale urban development and redevelopment, as well as by using place-making as a tool for city branding. This approach has also been used in other countries and has been constantly criticized for replacing old...journal article 2020

Qu, Y. (author)Vortex-induced vibration (VIV) is awell-known phenomenon for civil and offshore structures. Currently, the prediction of this type of vibration in practice currently mainly relies on the force-decomposition method. However, the limitations of this method have restricted the applicability of the method, and alternative models are therefore needed...doctoral thesis 2019

Qu, Bingyan (author), Zhou, Rulong (author), Wang, L. (author), Dorenbos, P. (author)How the 3d transition metal (TM) ions induce defect levels in wide band gap compounds and how these defect levels evolve from compound to compound is very important in understanding and predicting the luminescent properties of TM activated phosphors. This issue is discussed by studying the ground state 3d<sup>n</sup> level locations of the TM...journal article 2019

Qu, W. (author), Rezaei, J. (author), Maknoon, M.Y. (author), Tavasszy, Lorant (author)Hinterland freight transportation is managed according to a pre-designed schedule. In daily operations, unexpected uncertainties cause deviation from the original plan. Thus replanning is needed to deal with the perturbations and complete the transportation tasks. This paper proposes a mixed-integer programming model to re-plan hinterland...journal article 2019

Wang, H. (author), Qu, C. (author), Jiao, Chongze (author), Ruszel, W.M. (author)A signed network represents how a set of nodes are connected by two logically contradictory types of links: positive and negative links. In a signed products network, two products can be complementary (purchased together) or substitutable (purchased instead of each other). Such contradictory types of links may play dramatically different roles...journal article 2019

Qu, C. (author), Zhan, X. (author), Wang, Guanghui (author), Wu, Jianliang (author), Zhang, Zi-ke (author)Many systems are dynamic and time-varying in the real world. Discovering the vital nodes in temporal networks is more challenging than that in static networks. In this study, we proposed a temporal information gathering (TIG) process for temporal networks. The TIG-process, as a node's importance metric, can be used to do the node ranking. As...journal article 2019
