A warp skeleton method was proposed to solve the descriptive issue of arbitrary 3D woven composite architecture,with the unit cell being decomposed into subcells/grids.

Global exponential periodicity of a class of impulsive neural networks;

This paper discusses the exponential stability of periodic solution for impulsive neural networks.

Analyzing the vibrating characteristics of warp yarns during weaving;

The paper introduces the production procedure in weaving jacquard fabric made of two different warp yarns on air jet loom,detailed the attentions and countermeasures in its yarn warping,sizing and weaving which solved the problem of two warp yarns being hanked,reduced weaving defects as warp snarl and fabric barre and thus the product quality and production efficiency are improved.
