The Complement of the Hugelschaffer’s Construction of the Egg Curve
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
Hügelschäffer’s construction, based on the distortion of the
ellipse construction, provides an egg-shaped curve. This curve is a
mixed cubic curve, the cubic hyperbolic parabola of type A. Curve is a
three-branched and ...
One Application of the Cone Surfaces on the Erdosh-Mordell inequality
(Novi Sad: Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
We discuss the spatial interpretation of the Erdös-Mordell inequality on the area of triangle ABC, and also consider the plane extension of this inequality.
Concave deltahedral rings based on the geometry of the concave antiprisms of the second sort
(Porto: Aproged - Associação dos Professores de Geometria e de Desenho, 2019)
We have shown that there is a link between the geometry of the CA II-nM’s with bases n∈{3, 4, 5} and that of the convex antiprisms with the same bases. An integer number (K) of CA II-nM’s fragments, can be used to form a ...
3D lattice panels based on the concave polyhedra of the second sort: ideas for architectural ornaments
(Beograd: Fakultet primenjenih umetnosti, Univerzitet umetnosti u Beogradu, Srbija, 2019)
Concave polyhedra of the second sort (abbreviated: C-II-n) constitute a group of polyhedra formed over regular n-sided base polygons and having a deltahedral lateral surfaces. This group includes: concave cupolae, concave ...
Numerical modelling of temperature fluctuations in superchilled fish loins packaged in expanded polystyrene and stored at dynamic temperature conditions
(23rd Iir International Congress of Refrigeration, 2011)
Thermal insulation of fresh fish packaging can substantially reduce negative effects of poor temperature management in chill chains. The aim of the current study was to experimentally and numerically investigate the ...
Creating 3D shapes by time extrusion of moving objects
(Domus Argenia Publisher,, 2017)
The idea behind this paper is to investigate forms created as time imprint of moving 2D and 3D objects through space while simultaneously changing their transformations: translation, rotation, scaling, etc. The movement ...
Terestričko lasersko skeniranje i 3D modelovanje vetrogeneratora / Terrestrial laser scanning and 3D modelling of wind-turbine generator
(Savez mašinskih i elektrotehničkih inženjera Srbije (SMEITS) - Društvo za obnovljive izvore energije, 2018)
Rastući trend reverznog inženjerstva, posebno u oblasti građevine, gde je akcenat na ob-novljivim izvorima energije, neposredno prati aktuelna rešenja mernih insturmenata, kao i softvera za procesuiranje dobijenih podataka, ...
Presentation and analysis of geometric structures of contemporary buildings in the world architecture / Prezentacija i analiza geometrijskih struktura objekata svetske arhitekture
(Scientific association for the development and affirmation of new technologies, BelgradeCentral Institute for Conservation, Belgrade, 2019)
The key-role in architectural design of contemporary buildings certainly lays in geometry of their structure. The compliance of construction technologies and materials brought variety of attractive 3D structures, the ones ...
Determination of dynamic thermal characteristics of a building wall
(Mechanical Engineering Faculty, University of Niš, 2015)
In this paper, based on in situ experimental temperature measurements, the following dynamic thermal parameters of a wall were calculated: decrement factor, time shift of thermal transmittance and areal heat capacities. ...
Determination of the temperature transfer function of building constructions based on measurement data
(Materials Research Society of Serbia, 04-01-2015)
In this paper a method of determination of transfer function for temperature measured inside and outside residential building in Belgrade is presented. The instantaneous measurements of indoor temperature inside a living ...
