Mathematical Modeling of Integral Characteristics of Repair Process under Maintenance Contracts
(MDPI, 2021-12-08)
The repair rate is a very important parameter for system maintainability and can be defined as a frequency of successfully performed repair actions on a failed component per unit of time. This paper analyzes the integral ...
Novel Composite Approximation for the Gaussian Q-Function
(Kaunas University of Technology, 2020-10-27)
This paper, by using Borjesson’s and Benitez’s approximation of Q-function, presents a novel and improved composite approximation of Q-function with wide applicability. The presented approach is very general and can be ...
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 ...
A Novel Approach for Determination of Reliability of Covering a Node from K Nodes
(MDPI, 2020-09-05)
In this paper, a stochastic problem of multicenter location on a graph was formulated through the modification of the existing p-center problem to determine the location of a given number of facilities, to maximize the ...
MAXIMUM RELIABILITY K-CENTER LOCATION PROBLEM
(Union of Mathematicians of Macedonia - ARMAGANKA, 2020-10-31)
This paper presents an approach for solving the maximum reliability k-center location problem. We are modifying the well-known p-center problem in order to determine the location of the observed objects and maximize the ...
KORELACIJA IZMEĐU NAČINA AKTIVIRANJA MONTMORILONITA K10 I SADRŽAJA FORMALDEHIDA U UREA-FORMALDEHIDNIM KOMPOZITIMA
(Faculty of Management Herceg Novi, 2022-05-26)
U ovom radu je izvršeno poređenje načina aktiviranja montmorilonita (MMT) K10 sa sadržajem formaldehida (FA) u urea-formaldehidnim (UF) kompozitima. Uzorci MMT-a K10 su aktivirani na dva načina: termički i pomoću sumporne ...
Determination of glass transition temperature and irradiation resistance of elastomeric materials based on chlorinated natural rubber
(RAD Association, 2018-06-18)
Synthetic rubbers have different surface structures but benefit from chlorination. In many cases their tensile strength and extensibility is lower than natural rubber and for that reason more easily mechanically damaged. ...
The influence of the modification of the montmorillonite KSF and K10 on the hydrolytic stability of UF composites
(2021-09-24)
In this work, the hydrolytic stability of composites based on the urea-formaldehyde resin (UF) and montmorillonite-MMT (K1 0 and KSF) as a formaldehyde (FA) scavenger was investigated. K10 and KSF were activated by sodium ...
