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 ...
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. ...
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 ...
