Influence of the Wavelength on the Bandwidth in W-Type Plastic Optical Fibers
(Springer Link, 2021-07-03)
We investigate the bandwidth and steady-state losses of multimode W-type plastic optical fibers solving the time-dependent power flow equation and show how the bandwidth in W-type plastic optical
fibers can be enhanced ...
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 ...
Infrared wavelength dependence of leaky mode losses and steady state distribution in W-type glass optical fibers
(Elsevier, 2018-03-13)
Infrared wavelength dependence of leaky mode losses and steady state distribution
(SSD) in W-type glass optical fibers (doubly clad fibers with three layers) is
investigated in this paper for parametrically varied ...
Plant uptake and soil retention of radionuclides and metals in vineyard environments
In most European countries, each adult citizen drinks on averagemore than 20 L of wine every year. Three popular wine-growing areas (Aleksandrovac, Topola, and Orahovac) in Serbia were studied in order to investigate the ...
Mosses as bioindicators of radionuclide and metal pollution in northern Kosovo and Metohija mountain region
The study investigates mosses (Hypnum cupressiforme Hedw.) as bioindicators of pollution in three non-urban mountain areas of northern Kosovo and Metohija regions. Concentrations of radionuclides and metals were measured ...
Environmental radioactivity with respect to geology of some Serbian spas
(Springer, 2018-05-17)
This study was performed in order to investigate gamma dose rates, radon exhalation rates and soil radioactivity with respect to geology. Fifteen locations in three Serbian spas were under investigation. Gamma dose rate ...
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 ...
Dislocated quasi cone b-metric space over Banach algebra and contraction principles with application to functional equations
(De Gruyter Open Access, 2019-08-09)
In this paper we introduce dislocated and dislocated quasi version of a cone b-metric space over a Banach algebra as well as weak semi α-admissible and α-identical pair of mappings and prove common fixed point theorems for ...
Caristi, Nadler and H + -Type Contractive Mappings and Their Fixed Points in θ-Metric Spaces
(MDPI (Basel, Switzerland), 2019-04-07)
A new proper generalization of metric called as θ -metric is introduced by Khojasteh et al. (Mathematical Problems in Engineering (2013) Article ID 504609). In this paper, first we prove the Caristi type fixed point theorem ...
