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 ...
Pritisak na rečne obale i njihova transformacija usled izgradnje vikendica i sojenica: slučaj Savskog nasipa (Beograd).
(Asocijacija prostornih planera Srbije, Univerzitet u Beogradu- Geografski fakultet, 2020-11-10)
Na prostorima neposredno uz reke, zbog hidroloških, ekoloških i bezbednosnih razloga, kao i zakonskih odredbi, načela i principa planiranja, najčešće nije dozvoljena gradnja. Planska dokumenta ove prostore uglavnom definišu ...
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 ...
MAXIMUM RELIABILITY K-CENTER LOCATION PROBLEM
(Union of Mathematicians of Macedonia - ARMAGANKA, 2020-10-31)
This paper presents an approach for solving the maximum reliability k-center location problem. We are modifying the well-known p-center problem in order to determine the location of the observed objects and maximize the ...
Crosslinking of Polymers: Rubber Vulcanization
(Springer Nature Switzerland AG, 2020-10-02)
Crosslinking is a process whereby the polymer segments from different polymer chains are interconnected by covalent (and sometimes ionic) linkages. Crosslinks can be formed either during the polymer synthesis process, or ...
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 ...
