Ultra-wideband radio signals distribution in FTTH networks [PDF]

, 2008
The use of an ultra-wideband (UWB) radio technique is proposed as a viable solution for the distribution of high-definition audio/video content in fiber-to-the-home (FTTH) networks.

Friction stir welding of glass fiber-reinforced polyamide 6: Analysis of the tensile strength and fiber length distribution of friction stir welded PA6-GF30

IOP Conference Series: Materials Science and Engineering, 2019
Friction stir welding (FSW) is a solid state welding process that is preferably used for aluminum alloys. In the study described here, FSW was applied to glass fiber-reinforced polyamide 6 (PA 6) and evaluated in terms of weld strength and fiber length ...

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

Virtual 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.

Fast Characterization of Dispersion and Dispersion Slope of Optical Fiber Links using Spectral Interferometry with Frequency Combs [PDF]

, 2009
We demonstrate fast characterization (~1.4 microseconds) of both the dispersion and dispersion slope of long optical fiber links (~25 km) using dual quadrature spectral interferometry with an optical frequency comb.

Witnessing effective entanglement over a 2km fiber channel [PDF]

, 2010
We present a fiber-based continuous-variable quantum key distribution system. In the scheme, a quantum signal of two non-orthogonal weak optical coherent states is sent through a fiber-based quantum channel. The receiver simultaneously measures conjugate

Data-Driven Predictive Probability Density Function Control of Fiber Length Stochastic Distribution Shaping in Refining Process

IEEE Transactions on Automation Science and Engineering, 2020
Pulp is the most important raw material in paper industries, whose fiber length stochastic distribution (FLSD) shaping directly determines the energy consumption and paper quality of the subsequent papermaking processes.

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

, 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.
