Design of Few-Mode Fibers for Mode-Division Multiplexing Transmission

open access: yesIEEE Photonics Journal, 2013
We investigate the fiber parameters that meet the design conditions for low bending loss and an effectively few-mode operation on few-mode fibers with a step-index profile and a W-shaped refractive index profile for mode-division multiplexing ...

Stochastic Single-Dimensional Mutated Particle Swarm Optimization with Dynamic Subspace

open access: yesJisuanji kexue yu tansuo, 2020
The traditional particle swarm optimization algorithm adopts the overall dimension updating strategy, and the particle's fitness value deteriorates frequently because the optimal solution is not reached in a certain dimension or a few dimensions.

The effect of contact area on the permeability of fractures [PDF]

open access: yesJournal of Hydrology, 1992
Abstract The permeability of a rock fracture is controlled primarily by the geometry of its void space. One effect of void space geometry is to cause the fluid to follow a tortuous path to flow around the asperities, which are regions where the two faces of the fracture are in contact.
