Application of Mann-Kendal (MK) test in trend analysis of air temperature and precipitation: Case of Mačva district (Serbia)
(2020-06-30)
Recent climate changes cause significant natural and socio-economic consequences. They represent one of the major environmental problems of the late 20th and early 21st centuries. Changes in temperature and precipitation ...
Novel Composite Approximation for the Gaussian Q-Function
(Kaunas University of Technology, 2020-10-27)
This paper, by using Borjesson’s and Benitez’s approximation of Q-function, presents a novel and improved composite approximation of Q-function with wide applicability. The presented approach is very general and can be ...
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 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 ...
