Poset cone and weighted P−partitions enumerator
(Kongres mladih matematičara u Novom Sadu KMMNS2 Septembar, 29 – Oktobar, 1, 2022 Novi Sad, Srbija, 2022)
For a poset P on [n] we associate the poset cone C_P := cone{e_i − e_j : i <_P j}, where e_1, e_2, . . . , e_n are the standard basis vectors in R^n. The normal fan N(C_P) of this polyhedron is a coarsening of a subfan of ...

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 ...
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. ...
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 ...
An additional students’ task at Descriptive Geometry
(Faculty of Mechanical Engineering, University of Belgrade, 2020)
At the Faculty of Civil Engineering, University of Belgrade, beside the obligatory forms of lectures and exercises, freshmen students have the opportunity to widen their practical experience in application of geometric ...
Modeling the interior sunlight effects of Studenica Monastery
(Virtual Workshop: Natural Light in Medieval Churches Between Bizantium and West, 2020)
The local path of the Sun influences the architecture of our buildings. We have developed a model to measure the amount of sunlight that will pass through the windows of the Studenica Monastery Church. This model is general ...
Тhe benefits of an additional practice in descriptive geometry course: non obligatory workshop at the Faculty of civil engineering in Belgrade
(Serbian Society for Geometry and Graphics (SUGIG) Faculty of Mechanical Engineering, University of Belgrade, 2020)
At the Faculty of Civil Engineering in Belgrade, in the Descriptive geometry (DG) course, non-obligatory workshops named “facultative task” are held for the three generations of freshman students with the aim to give ...
