Wei, Zilong (author), Sun, Xianfu (author), Yang, Fei (author), Ke, Zaitian (author), Lu, Tao (author), Zhang, P. (author), Shen, C. (author)The presence of rail corrugation enlarges the wheel-rail impact and exacerbates the failure of track components, and the situation becomes even worse under high train speed, which promotes the urgent need for an efficient and easily accessible inspection method. Conventional diagnosis approaches such as axle box acceleration (ABA) and image...journal article 2022

(author), Ning, Fulong (author)Methane hydrate dissociation kinetics can be inhibited in NaCl solutions; however, this effect is reversed by promoting bubble formation that enhances dissociation. The negative and positive effects of inorganic salt injection on gas production from hydrate-bearing sediments are still controversial. Here, molecular dynamics simulations were...journal article 2022

Chen, Jiazhou (author), Xu, Yanghui (author), Lu, Shufang (author), Liang, Ronghua (author), Nan, L. (author)We present a novel 3-D instance segmentation framework for multiview stereo (MVS) buildings in urban scenes. Unlike existing works focusing on semantic segmentation of urban scenes, the emphasis of this work lies in detecting and segmenting 3-D building instances even if they are attached and embedded in a large and imprecise 3-D surface model....journal article 2022
