On the influence of resonance photon scattering on atom interference
(Physica Scripta, 2010)
Here, the influence of resonance photon-atom scattering on the atom interference pattern at the exit of a three-grating Mach-Zehnder interferometer is studied. It is assumed that the scattering process does not destroy the ...
Geometric proportional model of the church of the Ljubostinja monastery
(University of Arts in Belgrade Faculty of Applied Arts Kralja Petra 4, Belgrade,Serbia, 2020)
The use of proportions is one of the oldest theoretical issues in architecture. However, sometimes geometry, with its specific shapes and constraints
between them, can fully describe the logic of architectural design. ...
On the extension of the Erdös-Mordell type inequalities
(Mathematical Inequalities & Applications, 2014)
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Spatial forms create by time extrusion of moving objects
(Novi Sad: Digital Design Center / Department of Architecture / Faculty of Technical Sciences, University of Novi SadBeograd: Serbian Society for Geometry and Graphics (SUGIG), 2018)
The idea for this design came from investigation of forms created as “time imprint” of moving 2D and 3D objects through space, while simultaneously changing their transformations: translation, rotation, scaling, etc. The ...
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 ...
Trajectory-Based Interpretation of Laser Light Diffraction by a Sharp Edge
(Springer, 2018)
In the diffraction pattern produced by a half-plane sharp edge when it obstructs the passage of a laser beam, two characteristic regions are noticeable. There is a central region, where the diffraction of laser light appears ...
Geometry behind the position of stairs: balance in the mind
(Novi Sad:Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2018)
In this paper we examine the link between the human body and architectural design. For this purpose, we combine Cognitive Metaphor Theory (CMT) and geometry. We start from the hypothesis that the organization of space and ...
Some aspects of contemporary trends in civil engineering
(Peoples' Friendship University of Russia, 2014)
In this research several topics concerning contemporary civil engineering and architecture are introduced: problems regarding structural system choice (with respect to the geometric design of the building), suitable ...
Геометријски пропорцијски модел цркве манастира Љубостиња
(Факултет примењених уметности у Београду, 2019)
Пропорције архитектонских објеката се сматрају једним од најстаријих теоретских питања архитектуре, приближавајући се са једне стране математици, а са друге уметности-креативности у примени складних-хармоничних односа у ...
CFD simulation of thermal performances of building structure with expanded polystyrene (EPS) as thermal insulation
(Proceedings of 3rd International Conference on Electrical, Electronic and Computing Engineering IcETRAN 2016, Zlatibor, Serbia, June 13 – 16, 2016, 2016)
In this paper a three dimensional (3D), Computational Fluid Dynamics (CFD) simulation for indoor air flow and heat transfer in a single room was developed. The multi-layer structure building envelop, with expanded polystyrene ...
