Wang, Junpeng (author), Wu, J. (author), Westermann, Rüdiger (author)We present a visualization technique for 2D stress tensor fields based on the construction of a globally conforming lattice. Conformity ensures that the lattice edges follow the principal stress directions and the aspect ratio of lattice elements represents the stress anisotropy. Since such a lattice structure cannot be space-filling in...journal article 2020

(author), Townend, Ian (author), Wang, Zhengbing (author), He, Qing (author)Tidal waves traveling into estuaries are modified by channel geometry and river flow. The damping effect of river flow on incident astronomical tides is well documented, whereas its impact on low‐frequency tides like MSf and Mm is poorly understood. In this contribution, we employ a numerical model to explore low‐frequency tidal behavior under...journal article 2020

Wu, Juan (author), Bai, Min (author), Zhang, D. (author), Wang, Hang (author), Huang, Guangtan (author), Chen, Yangkang (author)Five-dimensional (5D) seismic data reconstruction becomes more appealing in recent years because it takes advantage of five physical dimensions of the seismic data and can reconstruct data with large gap. The low-rank approximation approach is one of the most effective methods for reconstructing 5D dataset. However, the main disadvantage of...journal article 2020

Wang, L. (author), Wu, Qing (author), Liu, Jialun (author), Li, Shijie (author), Negenborn, R.R. (author)At present, with the development of waterborne transport vehicles, research on ship faces a new round of challenges in terms of intelligence and autonomy. The concept of maritime autonomous surface ships (MASS) has been put forward by the International Maritime Organization in 2017, in which MASS become the new focus of the waterborne...journal article 2019

(author)Actuators using soft materials feature a large number of degrees of freedom. This tremendous flexibility allows a soft actuator to passively adapt its shape to the objects under interaction. In this paper, we propose a novel proprioception method for soft actuators during real-time interaction with previously unknown objects. First, we design...journal article 2019

Wang, W. (author), Munro, D.P. (author), Wang, C.C. (author), van Keulen, A. (author), Wu, J. (author)The design of optimal structures and the planning of (additive manufacturing) fabrication sequences have been considered typically as two separate tasks that are performed consecutively. In the light of recent advances in robot-assisted (wire-arc) additive manufacturing which enable addition of material along curved surfaces, we present a...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

Wang, Weiming (author), Liu, Yong-Jin (author), Wu, J. (author), Tian, Shengjing (author), Wang, C.C. (author), Liu, Ligang (author), Liu, Xiuping (author)Offsetting-based hollowing is a solid modeling operation widely used in 3D printing, which can change the model's physical properties and reduce the weight by generating voids inside a model. However, a hollowing operation can lead to additional supporting structures for fabrication in interior voids, which cannot be removed. As a consequence...journal article 2018
