A note on r-circulant matrices involving generalized Narayana numbers
(Journal of Mathematical Inequalities, 2023)
In order to further connect structured matrices and integer sequences, r-circulant matrices involving the generalized Narayana numbers are considered. Estimates for spectral norms bounds of such matrices are presented and ...
Primer kombinovanja raspodele atmosferskih aerosola po veličinama dobijenih metodom merenja električne pokretljivosti i optičkom metodom
(Zbornik radova, LXVI konferencija ETRAN, 2022)
Atmosferski aerosoli u urbanim sredinama se
sastoje od čestica različitih dijametara, koje mogu imati veličinu
od par nanometara do par mikrometara. Stoga je za merenje
koncentracije aerosola često neophodno koristiti ...
Two types of the second Hankel determinant for the class U and the general class S
(University of Tartu Press, Estonia, 2023)
In this paper we determine the upper bounds of the Hankel
determinants of special type H2(3)(f ) and H2(4)(f ) for the general class
of univalent functions and for the class U.
Challenges in teaching mathematics in Serbia
(International Multidisciplinary Conference "Challenges of Contemporary Higher Education" - CCHE 2024, 2024)
The purpose of this paper is to address the critical issue of the shortage of mathematics teachers and professors in Serbia. The old teaching staff is drying up, and there is a lack of new teaching potential. The demoralization ...

Influence of material surface roughness on backscattering in laser scanning
(University of Banja Luka, Faculty of Architecture, Civil Engineering and Geodesy, 2022)
In this paper, the possibility of applying Kirchhoff 's scalar approximation model for determining the backscattering coefficient from rough surfaces is investigated. Surfaces of dielectric and metallic materials, which ...
The third logarithmic coefficients for the class S
(Scientific and Technological Research Council of Turkey (TUBITAK) - Turkish Academic Network and Information Center (ULAKBIM), 2020)
In this paper we give an upper bound of the third logarithmic coefficient for the class $\mathcal{S}$ of univalent functions in the unit disc.
Pentagon-Based Radial Tiling with Triangles and Rectangles and Its Spatial Interpretation
(University of Arts in Belgrade, Faculty of Applied Arts, Kralja Petra 4, 11000 Belgrade, Serbia, 2022)
The paper considers a type of radial pentagon-based tiling consisting of two shapes: triangle and rectangle. The ob tained solution has a spatial interpretation in a 3D arrangement of equilateral triangles and squares ...
A method for adjusting the shape of semi-oval arches using Hügelschäffer’s construction
(Faculty of Technical Sciences, University of Novi SadSerbian Society for Geometry and Graphics SUGIG, 2023)
There are numerous ways to construct arches as curved structural elements that span openings in architectural buildings. Arches are present in many historical styles, having the role of an identification mark. Contemporary ...
