Simulation of fabric surface pattern by using yarn surface database.

Modeling friction for yarn/fabric simulation Application to bending hysteresis

This paper describes studies done at Gemtex Laboratory on the modeling and simulation of woven fabric. The main difficulty in this area is to take into account the hysteresis phenomena that occurs in fabric’s traction, shearing and bending behavior. Part I of this paper presents a friction based approach to obtain a time-free model for this nonlinear phenomena. Part II presents the application ...

Simulation of Surface Plasmon Excitation in a Plasmonic Nano-Wire Using Surface Integral Equations

In this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. First, integral equationsgoverning unknown fields on the surface is obtained based on Stratton-Cho surface integral equations. Then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. It is shown that in scatter...

Fabric Weave Pattern and Yarn Color Recognition and Classification Using a Deep ELM Network

Usually, a fabric weave pattern is recognized using methods which identify the warp floats and weft floats. Although these methods perform well for uniform or repetitive weave patterns, in the case of complex weave patterns, these methods become computationally complex and the classification error rates are comparatively higher. Furthermore, the fault-tolerance (invariance) and stability (selec...
