GIS analysis of land cover changes on the territory of the Prokuplje municipality
(Hindawi, 2014-01-03)
The monitoring of the territory of Prokuplje Municipality was done based on 1 : 25,000 topographic maps in three different time periods (1969, 1974, and 1984) and land cover map in 2012. Analogous topographic maps done in ...
Radionuclides and Metals in the Parks of the City of Belgrade, Serbia: Spatial Distribution and Health Risk Assessment.
In urban areas, forest patches and parks are usually the places where people spend most of their time outdoors. Due to the poor environmental protection policy and insufficient investment in industry and energy, Serbia is ...
THE TOTAL TORSION OF KNOTS UNDER SECOND ORDER INFINITESIMAL BENDING
(University of Belgrade - School of Electrical Engineering, 2021-10-26)
In this paper we consider infinitesimal bending of the second order of curves
and knots. The total torsion of the knot during the second order infinitesimal
bending is discussed and expressions for the first and the ...
“Soft Protein Corona” as the Stabilizer of the Methionine-Coated Silver Nanoparticles in the Physiological Environment: Insights into the Mechanism of the Interaction
(MDPI, 2022-08-11)
The study of the interactions between nanoparticles (NPs) and proteins has had a pivotal
role in facilitating the understanding of biological effects and safe application of NPs after exposure to the physiological ...
Calculation of the mode coupling coefficient in step-index plastic optical fibers based on the far field measurements
(Frontiers, 2022-05-25)
Using the power flow equation (PFE), this article investigates mode coupling in step-index
(SI) multimode (MM) polymer optical fiber (POF). This equation’s coupling coefficient was
initially fine-tuned so that it could ...
Transmission performance of multimode W- type microstructured polymer optical fibers
(Optica Publishing Group (Formerly OSA), 2022-06-23)
By solving the time-independent power flow equation (TI PFE), we study mode coupling in a multimode W-type microstructured polymer optical fiber (mPOF) with a solid-core. The multimode W-type mPOF is created by modifying ...
Theoretical Investigation of the Influence of Wavelength on the Bandwidth in Multimode W-Type Plastic Optical Fibers with Graded-Index Core Distribution
(MDPI, 2021-11-17)
The bandwidth of multimode W-type plastic optical fibers (POFs) with graded-index (GI) core distribution is investigated by solving the time-dependent power flow equation. The multimode W-type GI POF is designed from a ...
Calculation of Bandwidth of Multimode Step-Index Polymer Photonic Crystal Fibers
(MDPI, 2021-12-01)
By solving the time-dependent power flow equation, we present a novel approach for evaluating the bandwidth in a multimode step-index polymer photonic crystal fiber (SI PPCF) with a solid core. The bandwidth of such fiber ...
Investigation of bandwidth in multimode graded-index plastic optical fibers
(Optica Publishing Group, 2021-09-13)
A new method is proposed for investigating the bandwidth in multimode graded-index
plastic optical fibers (GI POFs). By numerically solving the time-dependent power flow equation,
bandwidth is reported for a varied launch ...
