The effect of hybrid models integration sequence: taking Fushun area as an example

Yongpeng Yang, Jingwei Chen, Ya Guo, Xin He et autres

Landslide susceptibility zoning (LSZ) is a crucial step in reducing landslide related losses, and its accuracy remains a long-standing research focus. Hybrid models are widely used, but little is known about coupling sequences. Here, we show that the accuracy of hybrid models …

3D numerical analysis of magnetization loss in twisted filamentary multilayer ReBCO tape

Zhixuan Zhang, Jun Ma, Nick Simpson

Multifilamentary structure can reduce the magnetization loss of ReBCO tapes by striating them into narrower filaments. But the loss reduction effect will be weakened due to the coupling current between filaments. The twisting of filaments can migrate the coupling effect and achieve …

Pattern-Forming Partial Differential Equations and Optimal Point Configurations

Zhixuan Zhang

This thesis investigates whether pattern-forming partial differential equations can serve as dynamical routes to solutions of classical geometric optimization problems on the sphere. At the planar level, we show that the Lifshitz--Petrich equation(LPe) generates defect-free single-domain hexagonal patterns from random initial conditions …

Mechanism and control of pillar bidirectional reinforcement during pre-cut roof gob-side entry driving in gently inclined coal seams

Dongdong Chen, Xiangyu Yang, Zhenquan Zhang, Wenkang Zhao et autres

Addressing the challenge of coal pillar stability control in gob-side entries of gently inclined coal seams, this study utilizes the 7134 working face of a specific mine as an engineering case. By integrating theoretical analysis, numerical simulation, physical similarity modeling, and field …
