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 ...

Most of our understanding of the physiologic effects of dietary fiber are derived from studies in adults. These investigations have indicated the potential problems with fiber consumption are most likely to occur if isolated polysaccharides or nonpurified fiber supplements are consumed excessively.

(CLEO). Conference on Lasers and Electro-Optics, 2005., 2005
Fiber lasers performance continues to increase due to advances in fiber design, with developments such as large mode area fibers, all-glass pump combiners, microstructured fiber and air-clad fiber allowing higher peak and average power.

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

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 ...

It is obvious that the effects of fiber on colonic functions are complex. The typical "Western diet" which is high in fat and protein and low in fiber may alter the bacterial flora and milieu interieur of the gastrointestinal tract, particularly the colon, to produce a high incidence of colonic cancer.

SPIE Proceedings, 2017
Research and development carried out by the ISF Welding and Joining Institute of RWTH Aachen University has proven that combining high power laser and low vacuum atmosphere provides a welding performance and quality, which is comparable to electron beam welding. The developed welding machines are still using a beam forming which takes place outside the

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 Devices Using Polarization-Maintaining Fibers
SPIE Proceedings, 1987Abstract Fiber devices using polarization-maintaining fibers called PANDA fibers are presented. They are polarization-maintaining couplers and polarization-splitting couplers, optical isolators and optical circulators, and multi/demultiplexers designed for 1.3 μm wavelength. Crosstalk of-32 dB and excess loss of 0.03 dB for the polarization-maintaining
