Numbers of Fiber-to-Fiber Contacts in General Fiber Assemblies
Textile Research Journal, 1977General formulas are derived for the estimation of the number of fiber-to-fiber contacts in fiber assemblies with arbitrary distributions of orientation and fiber length. The average number of contacts per unit volume of an assembly ñ v is given by ...

Fiber–fiber interaction in concentrated suspensions: Disperse fibers
Journal of Rheology, 1999A hypothesis for fiber–fiber interaction in planar randomly oriented concentrated fiber suspensions is proposed and tested. The idea is that at sufficiently high fiber concentrations, friction and lubrication at fiber–fiber contact points are the dominant interaction mechanisms.

Fiber sensors based on fiber gratings
2013 6th IEEE/International Conference on Advanced Infocomm Technology (ICAIT), 2013In this paper, we present two different types of pressure sensors including a high-sensitivity lateral pressure sensor and a temperature-independent differential pressure sensor by using fiber Bragg gratings to be encapsulated in a polymer-half-filled metal cylinder.

> MODERN ALCHEMY is changing not base metals, but polymers into gold. The manufacture of polymer fibers is one of today's fastest-expanding industries. With increasing demands for fibers for clothing, tires, space applications and a variety of other needs, the consumption of both natural and man-made fibers has increased by leaps and bounds during the ...

Fiber-optic gyroscope with polarization-holding fiber
Optics Letters, 1983A fiber gyroscope is reported that uses polarization-holding fiber in the coil, the phase modulator, and the coupler. The random-drift coefficient, calculated from rms noise levels, was 8.10(-4) deg/ radicalh, within a factor of 2 of an experimentally determined quantum and thermal limit. White-noise behavior was observed for integration time constants

Low-power infrared beams, which do not harm the eyes, are the means by which free-space optics (FSO) technology transmits data through the air between transceivers, or link heads, mounted on roof-tops or behind windows. It works over distances of several hundred meters to a few kilometers, depending upon atmospheric conditions. The authors believe that

The Annals of Mathematics, 1992
The authors consider projections \(\pi: P\to Q\) between convex polytopes. For each \(x\in Q\) the fiber \(\pi^{-1}(x)\) is again a convex polytope, and the average of \(\pi^{-1}(x)\) over all \(x\in Q\) is called the fiber polytope \(\Sigma(P,Q)\). Its precise definition is given in terms of the Minkowski integral which is the average of the integral ...

Journal of Lightwave Technology, 2003
Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air holes that run along the entire fiber length. Largely through their ability to overcome the limitations of conventional fiber optics—for example, by permitting low-loss guidance of light in a hollow core—these fibers are proving to have a multitude of ...
