Toward Inclusive, Vital and Livable City Scenarios: The Transformation of Urban Villages in ShenzhenQu, L. (author)Currently Shenzhen is experiencing industrial upgrading and city reprofiling, transforming from a world factory to a world city. It is a crucial moment to rethink the future of urban villages in the city, informal settlements that emerged extensively along with rapid industrialization and urban development in the past three decades, and played...book chapter 2020

Shen, Qiaomu (author), Wu, Yanhong (author), Jiang, Yuzhe (author), Zeng, Wei (author), Lau, Alexis K.H. (author), Vilanova Bartroli, A. (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

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

Beh, Gein Khai (author), Wang, Chang Ting (author), Kim, Kyungduk (author), Qu, Jiangtao (author), Cairney, Julie (author), Ng, Yun Hau (author), An, Alicia Kyoungjin (author), Ryoo, Ryong (author), Urakawa, A. (author), Teoh, Wey Yang (author)Solid acids of amorphous silica-alumina (a-SA) and amorphous silica-alumina-phosphate (a-SAPO) were prepared by flame spray pyrolysis (FSP). Careful tuning of the acidity of the solid acids was enabled by capitalizing on the advantage of FSP in preserving the metal stoichiometry (i.e., Si, Al, P) in the product nanoparticles. Although the...journal article 2020

Amenta, L. (author), Qu, L. (author)This paper aims to demonstrate how ‘research by design,’ which is an approach bridging research, design, and planning, can help unpack the complexity of today’s metropolitan challenges by considering the resource flows and processes that were omitted by traditional ways of planning. This is crucial for circular developments. By reporting the...journal article 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

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, 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
