An adaptive Kriging method based on K-means clustering and sampling in n-ball for structural reliability analysis

Jinsheng Wang, Zhiyang Cao, Guoji Xu, Jian Yang, Ahsan Kareem

Assessing the failure probability of engineering structures is still a challenging task in the presence of various uncertainties due to the involvement of expensive-to-evaluate…

Determination of the space-dependent blood perfusion coefficient in the thermal-wave model of bio-heat transfer

M.A. Alosaimi, D. Lesnic

When modeling heat propagation in biological bodies, a non-negligible relaxation time (typically between 15-30 s) is required for the thermal waves to accumulate and transfer…

Investigation on dynamic mathematical model and control method of flue gas heat exchange system

Hongqiang Ma, Yue Xie, Xingpeng Song, Yu Liu, Xinmei Luo, Shengxun Wang

The purpose of this paper is to recover the waste heat of flue gas heat exchanger (FGHE) as efficiently as possible and avoid the acid dew corrosion of that.

Research on the clogging law of floating particles on the rain grate of road surface

Jingming Hou, Xuan Nan, Guodong Li, Xuedong Wang, Sipeng Zhu, Yongde Kang

Since surface runoff clogs stormwater grates, leading to deterioration of drainage capacity, and also it is difficult to complete the study with actual dimensions in experiments…

A multi-fidelity surrogate model based on extreme support vector regression: fusing different fidelity data for engineering design

Mao-Lin Shi, Liye Lv, Lizhang Xu

Extreme support vector regression (ESVR) has been widely used in the design, analysis and optimization of engineering systems of its fast training speed and good computational…
