Certain properties of the class of univalent functions with real coefficients
(Korean Mathematical Society, 2023)
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 ...
Коришћење UAV фотограметрије и ласерског скенирања из ваздуха (LiDAR) приликом праћења активности клизишта на Умци
(Универзитет у Београду - Факултет безбедности, 2023)
Клизишта, као природне непогоде, егзистирају годинама, па у неком случајевима и више деценија. Због штетних последица које проузрокују, а како би се потенцијална опасност благовремено уочила и на време спречила, потребно ...
Dimensions reflected - catalog
(Faculty of Mechanical Engineering, University of Belgrade, 2020)
The 7th International Conference MoNGgeometrija 2020 is organized and supported by Serbian Society for Geometry and Graphics (SUGIG) and the Faculty of Mechanical Engineering, University of Belgrade. Since SUGIG considers ...
Geometric Properties of the “Flower” Concave Antiprisms of the Second Sort
(Belgrade: Serbian Society for Geometry and Graphics (SUGIG); Faculty of Mechanical Engineering, University of Belgrade, 2020)
This study presents a continuation of the research on the concave polyhedra of the second sort, adding to this family a new group of related polyhedra. They are formed over a specific type of isotoxal concave polygons that ...
Deltahedral Column Capitals
(Faculty of Mechanical Engineering, University of Belgrade, 2020)
Concave polyhedra of the second sort are a common name for polyhedra whose lateral surface is deltahedral, composed of a double row of equilateral triangles arranged in a 2π polar array over a regular polygonal base. Using ...
Experimental determination of dynamic parameters of heat passage through the facade wall of a weekend cottage on mountain Kopaonik, Serbia
(Faculty of civil engineering and architecture / University of Niš and Serbian academy of sciences and arts - branch in Niš, 2023)
In this paper, using a dynamic RC model for heat transfer in a room on the ground floor,
the three-time constants of heat transfer that corresponds to the different parts of a
weekend cottage on Kopaonik were determined. ...
Tilings with diamond, star and pineapple shapes based on the geometry of the regular pentagon
(Serbian Society for Geometry and Graphics (SUGIG)Faculty of Mechanical Engineering, University of Belgrade, 2021)
This paper presents a gallery of tessellations created by combining the following equilateral shapes: diamonds and stars, which can be further assembled into a pineapple shape. These three shapes can be decomposed into ...
Three-Dimensional Rosettes Based on the Geometry of Concave Deltahedral Surfaces
(Факултет примењених уметности, Београд, 2020 Faculty of Applied Arts, Belgrade, 2020, 2020)
In this paper concave deltahedral surfaces are applied to link the two concepts of geometric rosette design – the polar distribution of the unit element (circular arc) around the center of the contour circle and the rosettes ...
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 ...
