Huang, F. (author), Xia, Z. (author), Li, F. (author), Guo, L. (author), Yang, F. (author)Hydrological changes of the Irtysh River were analyzed concerning the changes of annual runoff and its distribution features within a year measured by coefficient of variation and concentration degree. Abrupt changes were detected by the heuristic segmentation method. Possible causes of the hydrological changes were investigated considering...journal article 2012

Yang, Z. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)This paper presents a full finite element (FE) interaction model of wheel-track to study the wheel-rail impact noise caused by squat. The wheel, the rail and some other track components are modeled with finite elements in three dimensions, where necessary and appropriate. Realistic contact geometry, including geometric irregularity (squat) in...conference paper 2013

(author)This paper presents a full finite element (FE) model of wheel-track interaction to study the wheel-rail impact noise excited by an insulated joint (IJ). The integration is performed in the time domain with an explicit central difference scheme. The vibratory behaviour of the track and wheel model are respectively validated with hammer test and...conference paper 2014

Ying, Shen (author), Jin, Fengzan (author), Guo, Renzhong (author), Li, Lin (author), Yang, Jie (author), Zhou, Yujie (author)Due to the fast growth of building construction technology and increasing demands on the efficient use of land, human living space are expanded from on the surface to above and under the earth surface. It raises the need for three dimentional (3D) cadastral by realizing that the current cadastral system based on 2D is not appropriate to reflect...conference paper 2014

Yang, Z. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)The precise mechanism which activates squeal, especially flange squeal has not been fully explained. The complex non-Hertzian contact and the broad-band high frequency feature bring great challenges to the modelling work of flange squeal. In this paper, an explicit integration finite element method is presented to simulate the dynamic curving...conference paper 2015

Yang, Z. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)By considering real wheel and track geometry and structures, as well as their coupled interaction, an explicit finite element method is applied to simulate the transition of wheel–rail rolling from single-point tread contact to two-point tread-flange contact. The evolutions of the contact position, stress magnitude and direction, adhesion–slip...journal article 2016

Yang, L. (author), Li, Pengdeng (author), Yang, Xiaofan (author), Tang, Yuan Yan (author)Advanced persistent threats (APTs) pose a grave threat to cyberspace, because they deactivate all the conventional cyber defense mechanisms. This paper addresses the issue of evaluating the security of the cyber networks under APTs. For this purpose, a dynamic model capturing the APT-based cyber-attack-defense processes is proposed....journal article 2017

Lu, Dan (author), Yang, Shunkun (author), Zhang, Jiaquan (author), Wang, H. (author), Li, Daqing (author)Epidemic propagation on complex networks has been widely investigated, mostly with invariant parameters. However, the process of epidemic propagation is not always constant. Epidemics can be affected by various perturbations and may bounce back to its original state, which is considered resilient. Here, we study the resilience of epidemics on...journal article 2017
