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 mode coupling on angular division multiplexing in seven-core plastic optical fibers
(IOP Science, 2020-05-11)
We propose an angular division multiplexing in new designed multicore plastic optical fiber
with seven cores arranged in a hexagonal array. The influence of mode coupling on two-channel
angular division multiplexing ...
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 ...
Analysis of adaptive e‐learning systems with adjustment of Felder‐Silverman model in a Moodle DLS
(Wiley, 2020-05-07)
E‐learning, as a complex system, includes distance learning, teaching materials in various forms and shapes, group and individual learning processes, as well as interactive and tutorial work. To increase the effectiveness ...
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH GmbH, 2020-09-08)
The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ...
Statistical causality and separable processes
(Science Direct, 2020-11-21)
In this paper we consider the statistical concept for continuous-time stochastic processes,
which is based on Granger’s definition of causality. We, also, show that separability
is directly related to causality concepts. ...
