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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Average Bit Error Rate Calculation Based on Using Piecewise Spline Approximation
In this paper, an approximation of the average bit error rate (ABER) probability expression, standard performance measure of wireless transmission over fading channels using linear spline functions with corresponding number ... -
Efficient Numerical Methods for Analysis of Square Ratio of kappa-mu and eta-mu Random Processes with Their Applications in Telecommunications
We will provide statistical analysis of the square ratio of and random processes and its application in the signal-to-interference ratio (SIR) based performance analysis of wireless transmission subjected to the influence ... -
