Combining size distribution spectrums of ambient aerosols using equivalent optical properties of nanosized particles selected examples from the Bay of Kotor
(16th Photonics Workshop: Kopaonik, March 12-15, 2023)
Atmospheric aerosols in urban areas typically consist of particles of different
diameters, which can range in size from a few nanometers to a few micrometers and can have
a strong impact on human health [1,2]. This ...
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 ...
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 ...
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 ...

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 ...
Pentagon-based radial tiling with triangles and rectangles and its spatial interpretation
(Faculty of Applied Arts, University of Arts in Belgrade, Serbia, 2021)
The paper considers a type of radial pentagon-based tiling consisted of two shapes: triangle
and rectangle. The obtained solution has a spatial interpretation in a 3D arrangement of
equilateral triangles and squares ...
