Optimization of anchorage location of three dimensional slopes based on improved differential evolution algorithm

Yantu gongcheng xuebao, 2020
Based on the improved differential evolution algorithm, considering the 3D spatial distribution of anchoring force through calculation of the 3D anchoring force, the anchorage position of 3D slope is optimized reasonably to save the number of bolts.

Unwinding of a cholesteric liquid crystal and bidirectional surface anchoring

, 2013
We examine the influence of bidirectional anchoring on the unwinding of a planar cholesteric liquid crystal induced by the application of a magnetic field. We consider a liquid crystal layer confined between two plates with the helical axis perpendicular
