Modelling shape of architectural structure: Elliptic hyperboloid of one sheet
(Institut za arhitekturu i urbanizam Srbije, Beograd, 2014)
The combination of straight lines of constructive elements and curved contours of structural shapes is always challenging in the engineering practice. The 2nd order surface - elliptic hyperboloid of one sheet (ELHY) provides ...
On the radius and the relation between the total graph of a commutative ring and its extensions
(Srpska akademija nauka i umetnosti SANU - Matematički institut, Beograd, 2011)
We discuss the determination of the radius of the total graph of a commutative ring R in the case when this graph is connected. Typical extensions such as polynomial rings, formal power series, idealization of the R-module ...
Perception of 3D Virtual Road Markings - Based on Estimation of Vehicle Speed
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Excessive speed and poor drivers' perception are the causes of a large number of traffic accidents. Analysis of the influence of geometry in drivers' behavior has been widely performed by different researchers. One way to ...
Polyhedral Forms Obtained by Combinig Lateral Sheet of CP II-10 and Truncated Dodecahedron
(Beograd:University of Belgrade, Faculty of Mechanical Engineering, 2017)
The paper analyzes the possibility of obtaining polyhedral shapes formed by combining polyhedral surfaces based on the segment surface of elongated concave pyramids of the second sort (CeP II-10, type A and type B). In ...
The pencil of the 4th and 3rd order surfaces obtained as a harmonic equivalent of the pencil of quadrics through a 4th order space curve of the 1st category / Pramen površi 4. i 3. reda dobijen kao harmonijski ekvivalent pramena kvadrika kroz prostornu krivu 4. reda 1. vrste
(Univerzitet u Nišu, Niš, 2012)
This paper shows the process of inverting the 4th ordered space curve of the first category with a self-intersecting point (with two planes of symmetry) and determining its harmonic equivalent. There are harmonic equivalents ...
Polyhedral forms obtained by combinig lateral sheet of CP II-10 and truncated dodecahedron / Poliedarske forme nastale spajanjem omotača CP II-10 i zarubljenog dodekaedra
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
The paper analyzes the possibility of obtaining polyhedral shapes formed by combining polyhedral surfaces based on the segment surface of elongated concave pyramids of the second sort (CeP II-10, type A and type B). In ...
On the properties of the concave antiprisms of second sort / O osobinama konkavnih antiprizmi druge vrste
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
The paper examines geometrical, static and dynamic properties of the polyhedral structures obtained by folding and creasing the two-rowed segment of equilateral triangular net. Bases of these concave polyhedra are regular, ...
