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 ...
On some F−contraction of Piri-Kumam-Dung type mappings in metric spaces
(2020-07-15)
This paper establishes some new results of Piri–Kumam–Dung-type mappings in a complete metric space.Тhe goal was to improve the already published results.
Methods: Using the property of a strictly increasing function as ...
On Recent Results Concerning F-Contraction in Generalized Metric Spaces
(MDPI (Basel, Switzerland), 2020-05-11)
In this manuscript we discuss, consider, generalize, improve and unify several recent results for so-called F-contraction-type mappings in the framework of complete metric spaces. We also introduce (φ,F) -weak contraction ...
On Some New Results in Graphical Rectangular b-Metric Spaces
(MDPI (Basel, Switzerland), 2020-04-01)
In this paper, we provide an approach to establish the Banach contraction principle (for the case λ∈[0,1)) , Edelstein, Reich, and Meir–Keeler type contractions in the context of graphical rectangular b-metric space. The ...
On F-Contractions for Weak α-Admissible Mappings in Metric-Like Spaces
(MDPI (Basel, Switzerland), 2020-09-21)
In the paper, we consider some fixed point results of F-contractions for triangular α-admissible and triangular weak α-admissible mappings in metric-like spaces. The results on F-contraction type mappings in the context ...
Statistics of simultaneous Rice, Nakagami-m and α−μ fadings after SC combining
(2020 19th International Symposium INFOTEH-JAHORINA (INFOTEH), 2020-04-16)
This paper presents initial results of a research towards statistical description of diversity-combined wireless signals that propagate over different environments. This kind of situation is encountered when receiver has ...
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 ...
Optimization and Validation of Kinetic-Spectrophotometric Technique for the Determination of Pesticide Dicamba in Infant Baby Foods Using Solid Phase Extraction Method
(HARD Publishing Company s.c., 2020-09-08)
The objective of this paper was to develop and apply the kinetic-spectrophotometric method for the determination of the pesticide dicamba in infant baby foods available in Serbia. The method is based on the inhibition ...
Design and Analysis of Binary Scalar Quantizer of Laplacian Source with Applications
(MDPI, 2020-10-27)
A compression method based on non-uniform binary scalar quantization, designed for
the memoryless Laplacian source with zero-mean and unit variance, is analyzed in this paper. Two quantizer design approaches are presented ...
