A Novel Approach for Determination of Reliability of Covering a Node from K Nodes
(MDPI, 2020-09-05)
In this paper, a stochastic problem of multicenter location on a graph was formulated through the modification of the existing p-center problem to determine the location of a given number of facilities, to maximize the ...
Hydrolytic, thermal, and UV stability of urea-formaldehyde resin/thermally activated montmorillonite nanocomposites
(Wiley, 2020-09-16)
Urea-formaldehyde resin (F/U ratio of 0.8)/thermally activated montmorillonite (UF/ΔTK10) nanocomposite was synthesized. The hydrolytical, thermal, and UV radiation stability of UF/ΔTK10 nanocomposites are determined. UF ...
Influence of mode coupling on three spatially multiplexed channels in multimode graded index plastic optical fibers
(IOP Science, 2020-10-27)
The influence of mode coupling on three-channel spatial division multiplexing capability in
multimode graded index plastic optical fibers is investigated by solving the power flow
equation. Our numerical results show ...
Spatial division multiplexing in nine-core graded index plastic optical fibers
(IOP Science, 2020-07-28)
We propose a spatial division multiplexing in a new designed multimode multicore graded index
plastic optical fiber with nine cores arranged in an octagonal array. The influence of mode
coupling on two-channel spatial ...
Influence of wavelength on the bandwidth of W-type plastic-clad silica optical fibers
(IOP Science, 2020-01-07)
The bandwidth and steady-state loss of multimode W-type plastic-clad silica optical fibers are
investigated by solving the time-dependent power flow equation. The results show how the
bandwidth of W-type plastic-clad ...
Influence of wavelength on equilibrium mode distribution and steady state distribution in W-type plastic optical fibers
(IOP Science, 2020-05-27)
Wavelength dependence of equilibrium mode distribution (EMD) and steady state distribution
(SSD) in W-type plastic optical fibers (POFs) is investigated in this paper for parametrically
varied width of the fiber’s ...
On Some New Jungck–Fisher–Wardowski Type Fixed Point Results
(MDPI (Basel, Switzerland), 2020-12-10)
Many authors used the concept of F−contraction introduced by Wardowski in 2012 in order to define and prove new results on fixed points in complete metric spaces. In some later papers (for example Proinov P.D., J. Fixed ...
