Vibration Characteristics of Subway Tunnel Structure in Viscous Soil Medium by Dawei Ren, Shengjun Shao, Xiaoshan Cao, Yifeng Hu

“…The soil around the tunnel is represented in simplified form as an isotropic viscoelastic medium to obtain the equation of motion of the soil, and the vibration control equation of the tunnel under the influence of viscous soil is obtained by coupling. By numerical calculations, the variation trends in the natural vibration frequency of the tunnel and attenuation affected by soil viscosity under different modes are given. …”

A method of micro-blog topic discovery based on feature words selection and text similarity by Hongyang CHEN, Linlin WANG, Yingsheng CHEN, Jiangkun LU, Xue ZUO

“…Some words existing in micro-blog short text have a bad effect on the accuracy of text similarity calculation,further affecting the quality of topic discovery.And these words are the same in shape or semantic meaning,but remote from the topic.A novel method of feature words selection based on micro-blog short text content and structured information was proposed,which could effectively choose some important feature words from the text.Moreover,in computing the similarity between texts,an improvement on computing the similarity between the text and the topic was made.Finally,the methods were combined together and applied to discover micro-blog topics.Experimental results show that the new method of topic discovery can effectively reduce the average missing rate and false detection rate,and improve the quality of topic discovery.…”

The role of CO on initial oxidation behavior of α-U(001) surface: A first principles study by Longxian Li, Min Zhu, Yan Li, Yanru Ren, Longfei Pu, Chengxuan Peng

“…A first-principles approach based on density-functional theory has been used to investigate the corrosion resistance of alpha-U in the CO environment. Calculations show that O2 molecules spontaneously dissociate on the uranium surface, and the two O atoms formed by dissociation tend to adsorb on the hole sites and bind to the surface in the form of a U–O bond to emit a large amount of heat. …”

Research on green light compensation model for emergency preemption in C-V2X environment by Changlong ZHANG, Farong HAN, Jimin WEI, Jingang DAI, Xiaodong YANG, Shibo QU

“…To reduce the impact of the emergency vehicle preemption strategy on vehicles in non-priority phases at intersections, an emergency preemption green light compensation model in C-V2X environment was proposed.The proposed model doesn’t affect the emergency vehicle preemption strategy.The green time of the non-priority phases was calculated according to the real-time traffic demand to minimize the adverse impact on vehicles in non-priority phases.The proposed model was verified with simulation using an emergency vehicle.The results demonstrate that the proposed method can effectively decrease the queue lengths and reduce the average delay in non-priority phases after applying the emergency vehicle preemption strategy.The proposed method can improve traffic efficiency by optimizing the signal timing after the emergency vehicle passes through an intersection.…”
