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

Scharff, R.B.N. (author), Doornbusch, Rens M. (author), Doubrovski, E.L. (author), Wu, J. (author), Geraedts, Jo M.P. (author), Wang, C.C. (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

Zhu, Jianbo (author), Shi, Q. (author), Wu, Peng (author), Sheng, Zhaohan (author), Wang, Xiangyu (author)In the process of internationalization of construction contractors, international enterprises as main contractors (IMC) need to consider whether part of the contract should be subcontracted to local subcontractors (LSC) to gain a competitive advantage when competing with local main contractors (LMC). The involvement of local subcontractors...journal article 2018

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

Yi, Ran (author), Wu, Chenming (author), Liu, Yong-Jin (author), He, Ying (author), Wang, C.C. (author)This paper presents a 3-D printing system that uses a low-cost off-the-shelf consumer projector to fabricate large models. Compared with traditional digital light processing (DLP) 3-D printers using a single vertical carriage, the platform of our DLP 3-D printer using delta mechanism can also move horizontally in the plane. We show that this...journal article 2018

Sun, Chuan (author), Wu, Chaozhong (author), Chu, Duanfeng (author), Lu, Z. (author), Tan, Jian (author), Wang, Jianyu (author)This paper aims to recognize driving risks in individual vehicles online based on a data-driven methodology. Existing advanced driver assistance systems (ADAS) have difficulties in effectively processing multi-source heterogeneous driving data. Furthermore, parameters adopted for evaluating the driving risk are limited in these systems. The...journal article 2018

Liu, Xiuping (author), Lin, Liping (author), Wu, J. (author), Wang, W. (author), Yin, Baocai (author), Wang, C.C. (author)Wireframe models are becoming a popular option in 3D printing. Generating sparse wireframe models using classic mesh simplification methods leads to models that require a lot of support structures in the layer-upon-layer additive process. In this paper we present a mesh simplification method that takes into account the overhang angle....journal article 2018

(author), Ando, Yoichi (author), Wu, Weida (author), Bode, Matthias (author)Recently, the doping of topological insulators has attracted significant interest as a potential route towards topological superconductivity. Because many experimental techniques lack sufficient surface sensitivity, however, definite proof of the coexistence of topological surface states and surface superconductivity is still outstanding....journal article 2018

(author), Liu, Yong-Jin (author)This paper presents a new method to fabricate 3D models on a robotic printing system equipped with multi-axis motion. Materials are accumulated inside the volume along curved tool-paths so that the need of supporting structures can be tremendously reduced - if not completely abandoned - on all models. Our strategy to tackle the challenge of...journal article 2018
