In order to more effectively monitor the health of composite structures, a fuzzy fiber sensor has been developed. The fuzzy fiber is a bundle of glass fibers with carbon nanotubes or nanofibers (CNTs or CNFs) grown on the surface. The nanotube coating makes the fiber bundle conductive while the small conductive path increases sensitivity. The fuzzy fiber sensor can replace conventional metal fo...

Given a vector bundle on P1 bundle, the base is stratified by degeneracy loci measuring splitting type of restricted to each fiber. The classes these in Chow ring or cohomology are natural invariants characterizing degenerations bundle. When occur expected codimension, we find their classes. This yields universal formulas for terms naturally arising bundles base. existence applied prove non-emp...

We discuss the cooperative failure dynamics in fiber bundle model where individual elements or fibers are Hookean springs that have identical spring constants but different breaking strengths. When is stressed strained, especially equal-load-sharing scheme, load supported by failed gets shared equally rest of surviving fibers. This mean-field-type statistical feature (absence fluctuations) load...
