Vukojević, Vesna; Đurđić, Slađana; Jevtić, Sonja; Pergal, Marija; Marković, Aleksandar; Mutić, Jelena; Petković, Branka; Stanković, DaliborIn this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. ... -
Influence of zero boresight and non-zero boresight pointing error on BER FSO transmission over Malaga atmospheric channel
Smilić, Marko; Perić, Zoran; Milić, Dejan; Marković, Aleksandar; Savić, Milan (Oficyna Wydawnicza Politechniki Wroclawskiej, 2018-03-22)In this paper, the influence of a zero and a non-zero boresight pointing errors on the performances of free-space optic transmission over the Málaga atmospheric turbulence channel is considered. Closed form expressions for ... -
Mathematical Approach for System Repair Rate Analysis Used in Maintenance Decision Making
Kontrec, Nataša; Panić, Stefan; Panić, Biljana; Marković, Aleksandar; Stošović, Dejan (MDPI, 2021-05-20)Reliability, the number of spare parts and repair time have a great impact on system availability. In this paper, we observed a repairable system comprised of several components. The aim was to determine the repair rate ... -
Novel Composite Approximation for the Gaussian Q-Function
Perić, Zoran; Marković, Aleksandar; Kontrec, Nataša; Panić, Stefan; Spalević, Petar (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 ... -
An Overview of Novel Methods for ASEP Performance Evaluation Based on Q-Function Approximation
Marković, Aleksandar; Perić, Zoran; Panić, Stefan (27th Telecommunications forum TELFOR 2019, 2019-11-27)The closed-form expression for Q-function does not exist so it is necessary to develop its approximation in order to overcome the difficulties that might appear in diverse research areas. In this paper the authors are ... -
Two Interval Upper-Bound Q-Function Approximations with Applications
Perić, Zoran; Marković, Aleksandar; Kontrec, Nataša; Nikolić, Jelena; Petković, Marko; Jovanović, Aleksandra (Mathematics and computer sciences, 2022-10-10)The Gaussian Q-function has considerable applications in numerous areas of science and engineering. However, the fact that a closed-form expression for this function does not exist encourages finding approximations or ...
