Use of Span Lengths Extracted from the HVI Fibrogram to Predict Yarn Quality

open access: yesJournal of Natural Fibers, 2023
Cotton fiber properties play a significant role in determining the quality of yarns and fabrics. Information on fiber length distribution is crucial throughout many textile processing steps to transform fibers into yarn.

Theoretical Investigation of Bandwidth in Multimode Step-Index Silica Photonic Crystal Fibers

open access: yesPhotonics, 2022
Solving the time-dependent power flow equation (PFE) provides a useful method to study the transmission bandwidth of step-index silica photonic crystal fibers (SI SPCFs). The transmission bandwidth of these kinds of fibers is determined for different air-

DISTRIBUTION OF FIBER LENGTH OF KOZO

open access: yesJournal of the Japanese Technical Association of the Pulp and Paper Industry, 1952
We treated the distributions of fiber length on the stand point of inductive statistics, and found to resemble the normal frequency distribution.We calculated the rejection limit under definite level of significance, and far we considered the difference between each samples.

Active fiber length distribution and its application to determine the critical fiber length

open access: yesPolymer Testing, 2009
Abstract A new test and evaluation method has been developed to determine the critical fiber length characteristic of short fiber reinforced composites. From the so-called active ‘barbe’ (beard) length distribution calculated from the length distribution of the fibers in the composite and from the length distribution of the fibers protruding from the

Influence of launch beam distribution on power flow and angular division multiplexing in seven-core silica optical fibers

open access: yesFrontiers in Physics, 2022
We analyze the effect of launch beam distribution on space-division multiplexing (SDM) performance in multimode multicore silica optical fibers (MM MC SOF) with seven cores.

Nondestructive characterization of fiber couplers by a local perturbation method [PDF]

open access: yes, 2002
A technique for the nondestructive characterization of fiber couplers is demonstrated. A CO2 laser beam is scanned along the coupler length inducing a local perturbation to the coupler eigenmodes.

Numerical investigation of fiber orientations and homogeneity in powder bed fusion of fiber/polymer composites

open access: yesVirtual and Physical Prototyping, 2023
The packing characteristics of fiber/polymer powder in powder bed fusion additive manufacturing exhibit a high correlation with the mechanical behaviours of printed composite parts such as homogeneity and anisotropy.

Protocol parameter selection for fiber-supported IEEE 802.16m networks [PDF]

open access: yes, 2014
In this paper we investigate protocol issues that might arise due to the extra fiber propagation delay in fiber-fed IEEE 802.16m networks. Our study indicates that although the fiber delay might affect network performance, an informed choice of protocol ...
