Publikováno v: IOP Conference Series: Earth and Environmental Science. 692:042122

From the beginning, human society has an insurance awareness to deal with disasters and an insurance concept to accumulate wealth. In the spring and Autumn Period, Confucius’ thought of “spelling more than one” is quite representative. As an im

Traffic collisions early warning aided by small unmanned aerial vehicle companion

Autor: Zhenfei Wang, Hao Luo, Shu-Chuan Chu, Xiaofeng Wu, Fangqian Xu

Publikováno v: Telecommunication Systems. 75:169-180

Most traffic surveillance systems are based on videos which captured by fixed cameras on bridges, intersections, etc. However, many traffic collisions may occur in many places without such surveillance systems, e.g., in rural highway. Researchers hav

An investigation of surface acoustic waves in an anisotropic crystal

Autor: Fangqian Xu

Publikováno v: 2012 International Conference on Image Analysis and Signal Processing.

A substrate of a surface acoustic waves (SAW) device is usually treated as a semi-infinite elastic body though it is virtually a finite elastic solid. With the two-dimensional theory, a new method is developed for the analysis of SAW propagating unde

The expansion of neighborhood and pattern formation on spatial prisoner's dilemma

Autor: Junzhong Yang, Xiaolan Qian, Fangqian Xu, Jürgen Kurths

Publikováno v: Chaos: An Interdisciplinary Journal of Nonlinear Science. 25:043115

The prisoner's dilemma (PD), in which players can either cooperate or defect, is considered a paradigm for studying the evolution of cooperation in spatially structured populations. There the compact cooperator cluster is identified as a characterist
