Hou, D. (author), Han, B. (author), Chen, W. (author), Liang, H. (author), Su, Q. (author), Dorenbos, P. (author), Huang, Y. (author), Gao, Z. (author), Tao, Y. (author)A series of Ce3+ doped ?-Sr2?2xCexNaxP2O7 phosphor compounds has been prepared using a high-temperature solid-state reaction technique. The luminescence properties under vacuum ultraviolet-UV and x-ray excitation were studied. Luminescence spectra reveal three UV-emitting peaks at about 310, 330, and 350 nm from which we conclude that Ce3+...journal article 2010

(author)In this paper, we propose an approach to autonomously control a quadrotor micro aerial vehicle (MAV). With take-off weight of 50 g and 8-min flight endurance, the MAV platform codenamed KayLion developed by the National University of Singapore (NUS) is able to perform autonomous flight with pre-planned path tracking. The vision-based...conference paper 2014

(author), Zhang, Kouchi (author)The color coordinate shift of light-emitting diode (LED) lamps is investigated by running three stress-loaded testing methods, namely step-up stress accelerated degradation testing, step-down stress accelerated degradation testing, and constant stress accelerated degradation testing. A power model is proposed as the statistical model of the...journal article 2017

Spectroscopic evidence for bulk-band inversion and three-dimensional massive Dirac fermions in ZrTe5Chen, Zhi Guo (author), Chen, R. Y. (author), Zhong, R. D. (author), Schneeloch, John (author), Zhang, C. (author), Huang, Y. (author), Qu, F. (author), Yu, R. (author), Li, Q. (author), Gu, G. D. (author), Wang, N. L. (author)Three-dimensional topological insulators (3D TIs) represent states of quantum matters in which surface states are protected by timereversal symmetry and an inversion occurs between bulk conduction and valence bands. However, the bulk-band inversion, which is intimately tied to the topologically nontrivial nature of 3D Tis, has rarely been...journal article 2017

Chen, Peng (author), Huang, Xiongchuan (author), Chen, Y. (author), Wu, Lianbo (author), Staszewski, R.B. (author)To characterize an on-chip programmable delay in a low-cost and high-resolution manner, a built-in self-test based on a first-order ΔΣ time-to-digital converter with self-calibration is proposed and implemented in TSMC 28-nm CMOS. The system is self-contained, and only one digital clock is needed for the measurements. A...journal article 2018

Huang, Y. (author), Chen, L. (author), van Gelder, P.H.A.J.M. (author)Numerous methods have been developed for ship collision prevention over the past decades. However, most studies are based on strong assumptions, such as the need for a constant velocity of the target-ship, the limitation to two-ship scenarios, the simplification of ships’ dynamics, etc. Generalized Velocity Obstacle (GVO) algorithm can bridge...journal article 2019

Huang, Yamin (author), Chen, Linying (author), Negenborn, R.R. (author), van Gelder, P.H.A.J.M. (author)Many Collision Avoidance Systems (CAS) for autonomous ships usually presume that a ship's dynamics are completely known in advance. However, precise parameters for ships in different operating conditions are, in fact, uncertain and unknown. The parameter identification of ship dynamics is challenging and time-consuming. Thus, uncertainties in...journal article 2020

(author)Federated Learning is an emerging distributed collaborative learning paradigm adopted by many of today's applications, e.g., keyboard prediction and object recognition. Its core principle is to learn from large amount of users data while preserving data privacy by design as collaborative users only need to share the machine learning models...conference paper 2020

(author)In this research, a hybrid approach for global path planning for Maritime Autonomous Surface Ship (MASS) is proposed, which generates the shortest path considering the collision risk and the proximity between path and obstacles. The collision risk concerning obstacles is obtained using Time-Varying Collision Risk (TCR) concept, taking into...journal article 2020

(author), Wei, Jiangxiong (author), Yu, Qijun (author)Concrete generally deforms and cracks in a non-uniform manner under drying-induced stress. This study used the lattice fracture model to simulate the drying-induced non-uniform deformations, stresses, and micro-crack propagation in concrete. Experiments were designed to validate the lattice fracture model, wherein the drying-induced non...journal article 2020

Researchers aim at developing fully autonomous systems that replace the role of human operators. Studies either focus on supporting conflict/collision detection (for manned ships) or solving conflict automatically (for unmanned ships). The cooperation...journal article 2020
