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 ...

Pravilne konkavne kupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
The term cupola stands for a polyhedron consisting of two regular polygons: n-gon and 2n-gon in parallel planes, connected by an alternating series of squares and equilateral triangles, ie. Johnsonsolids J3, J4 and J5. ...
Zlatni presek i pravilne konkavne bikupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
Zlatni presek (racio) predstavlja odnos između strane pravilnog pentagona i njegove dijagonale, a takođe se dovodi u vezu sa susednim članovima Fibonacijevog niza. Istraživaem i upoređivanjem metričkih parametara konkavnih ...
Investigating Composite Polyhedral forms obtained by combining concave cupolae of II sort with Archimedean Solids
(Novi Sad: Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
Concave cupolae of II sort, combined with the other concave or convex polyhedra with at least one matching side, provide many possibilities for the formation of various composite polyhedra. The paper presents research on ...

70 mm x 70 mm, which are made ...
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 ...
Geometrical Characteristics and Solid Modeling of the Grasshopper Escapement Mechanism
(Faculty of Civil Engineering and Architecture ; Serbian Society for Geometry and Graphics SUGIG, Niš ; Beograd, 2014)
This paper presents the geometrical properties of one special type of escapement mechanism – the grasshopper escapement, by which the first marine chronometers were equipped. The most important and distinguish mechanical ...
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 ...
