A Stochastic Model for Achieving Required Level of Availability Based on the Repair Rate Analysis
(Strojarski fakultet u Slavonskom Brodu; Fakultet elektrotehnike, računarstva i informacijskih tehnologija Osijek; Građevinski i arhitektonski fakultet Osijek, 2019-07-25)
The aim of this paper is to set framework for the repair rate in order to achieve required availability of a repairable system with alternating renewal process where the failure rate is Weibull distributed. In order to ...
Comparison of adaptive algorithms for free space optical transmission in Malaga atmospheric turbulence channel with pointing errors
(2019)
In this study, the authors investigate average capacity of free space optics communication over Málaga atmospheric turbulence channel with pointing errors and path loss, for intensity modulated/direct detection (IM/DD) and ...
Assessment of natural environment for the purposes of recreational tourism-example on Drina river flow (Serbia)
(European Association of Geographers (EUROGEO), 2019-09-10)
The role of applied geography has been increasing in interdisciplinary research due to the advantage of knowing spatial processes and relations. This role has reflected in the geo-ecological evaluations of a particular ...
System performances of sc reception in asymmetric multipath fading environments
(2019-06-23)
The paper takes into consideration dual-branch selection combining (SC) diversity reception technique in the presence of dissimilar fading at their branches. We efficiently obtained first and second order closed form ...
The vulcanization properties of hybrid elastomeric materials based on waste rubber powder
(University of Belgrade, Technical Faculty in Bor, 2019-06-18)
Elastomeric materials have viscoelastic properties and can be designed for numerous applications, tires production, vibration isolation and damping. These properties can be tailored for a wide temperature range and in ...
The influence of modification and the particle size of the montmorillonite on the hydrolytic stability of urea-formaldehyde composite
(Materials Research Society of Serbia, 2019-09-02)
Urea–formaldehyde (UF) resin adhesive is a polymeric condensation product of formaldehyde with urea and is considered as one of the most important wood adhesives. In spite of some advantages such as lower cost, fast curing, ...
The influence of the type of activation of the montmorillonite of hydrolytic stability of the urea-formaldehide nanocomposite
(University of Novi Sad, Faculty of Technology Novi Sad, 2019-10-10)
In this work the hydrolytic stability of nano-composites based on urea-formaldehyde resin (UF) and montmorillonite (K10) as formaldehyde scavenger was investigated. K10 was activated by sulfuric acid (H2SO4) with and without ...
The effect of UV irradiation on hydrolytic stability of urea-formaldehyde resins filled with thermally modified montmorillonite
(RAD Centre, Niš, Serbia, 2019-06-10)
The hydrolytic stability of organic-inorganic nano-composites prepared by a two-stage
polymerization of urea-formaldehyde resin (UF) filled with thermally activated montmorillonite (MMT) has been assessed before and after ...
The influence of montmorillonite activating method on the hydrolytic stability of urea-formaldehyde resin
(Faculty of Technology, Leskovac, 2019-10-18)
Montmorillonite clays are of great importance for processes such as adsorption and
catalysis and polymer composites fabrication . The textural properties of this filler can
be modified to increase their application. In ...
Strukturiranje elastomernih materijala za primenu u poljoprivredi
(UNIVERZITET U KRAGUJEVCU, AGRONOMSKI FAKULTET U ČAČKU, 2019-03-15)
Poljoprivreda i poljoprivredna industrija zahtevaju elastomeme proizvode koji mogu izdržati dugotrajnu izloženost ekstremnim naponima i hemikalijama. Elastomeri dobijeni od etilen-propilen-dienskog kaučuka (EPDM) nalaze ...
