Investigation of a Multivariate Correction Method for HVI Fibrogram Measurements

open access: yesAgronomy, 2022
Cotton fiber length parameters are used across the cotton industry to select elite germplasm, purchase cotton bales and manage mill throughput. The High Volume Instrument (HVI) provides the most commonly used fiber length parameters, upper half mean ...

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

Depolarization of light due to the optical Kerr effect in low-birefringence single-mode fibers [PDF]

open access: yes, 1986
The evolution of the state of polarization of an electromagnetic field propagating in a low-birefringence single-mode fiber in the presence of the nonlinear interaction associated with the optical Kerr effect is investigated.

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.

Quantum key distribution over 122 km of standard telecom fiber

open access: yes, 2004
We report the first demonstration of quantum key distribution over a standard telecom fiber exceeding 100 km in length. Through careful optimisation of the interferometer and single photon detector, we achieve a quantum bit error ratio of 8.9% for a ...

Adjustment of Cotton Fiber Length by the Statistical Normal Distribution: Application to Binary Blends [PDF]

open access: yesJournal of Engineered Fibers and Fabrics, 2008
In this study the normality of the cotton fiber length number distribution and weight distribution are tested by using the Chi-2 statistic test. Good correlations between the cotton fiber length distribution by weight and the normal distribution with the
