The assessment of aridity in Leskovac Basin, Serbia (1981-2010)
(2018-08-25)
In the paper, the aridity is defined on the basis of four climate indices: De Martonne's index of aridity, Lang’s Rain Factor and Gračanin’s Rain factor for the vegetation period and hydrothermal coefficient of Seljaninov. ...
A stochastic model for estimation of repair rate for system operating under performance based logistics
(Polish Maintanace Society, 2018-09-01)
Performance Based Logistics (PBL) concept has an aim to improve the system availability and it has been extensively researched in the recent years. These researches showed that inventory level does not impact system ...
Ternary NR/BR/SBR rubber blend nanocomposites
(SAGE, 2018-02-24)
The goal of this work was to synthesize and characterize ternary rubber blends based on polyisoprene (natural rubber (NR)), polybutadiene rubber (BR), and styrene–butadiene rubber (SBR) (NR/BR/SBR = 25/25/50) reinforced ...
Enhancement of the bandwidth of W-type glass optical fibers in the infrared wavelength region
(Elsevier, 2018-08-28)
Transmission characteristics (bandwidth and steady state loss) of multimode W-type glass optical fibers are investigated by solving the time-dependent power flow equation. Results show how the bandwidth in W-type glass ...
Calculation of the bandwidth of W-type photonic crystal fibers by time-dependent power flow equation
(Elsevier, 2018-06-30)
A multimode photonic crystal fiber with a solid-core takes the characteristic W-shaped index profile upon forming
an inner cladding layer with its own value of the effective refractive index corresponding to the distinct ...
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 ...
Environmental risk assessment of radioactivity and heavy metals in soil of Toplica region, South Serbia
(Springer, 2018-03-13)
Activity levels of natural and artificial radionuclides and content of ten heavy metals (As, Cd,
Co, Cr, Cu, Mn, Ni, Pb, Zn and Hg) were investigated in 41 soil samples collected from Toplica region located in the south ...
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 ...
C-class functions on some fixed point results in ordered partial metric spaces via admissible mappings
(Department of Mathematics and Informatics, Faculty of Sciences, Novi Sad, 2018-06-05)
In this paper, we generalized the results presented in the paper W. Long, S. Khaleghizadeh, P. Salimi, S. Radenović and S. Shukla, Some new fixed point results in partially ordered metric spaces via admissible mappings, ...
Some remarks on TAC-contractive mappings in b-metric spaces
(Društvo matematičara Srbije, 2018-09-03)
In this paper we complement and improve fixed point results established on
TAC-contractive mappings in the framework of b-metric spaces. Our analysis starts by a
recent paper of Babu and Dula [G. V. R. Babu and T. M. ...
