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 ...
Mathematical model for estimation of the three-dimensional unsteady temperature variation in chilled packaging units
(International Journal of Refrigeration-Revue Internationale Du Froid, 2012)
A mathematical model for heat transfer from surrounding environment to a single food package is developed. A simplified analytical solution for three-dimensional (3D) unsteady temperature distribution in the food package ...
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.
A Group Of Polyhedra Arised As Variations Of Concave Bicupolae Of Second Sort
(Novi Sad:Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
The paper presents the variations of polyhedral forms based on the geometry of concave cupolae of II sort. There were considered only variations that include bicupolae of II sort, with bases connected directly or indirectly ...
Concave Antiprisms of Second Sort with Regular Polygonal Bases
(Novi Sad: Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
The paper discusses determining the positions and spatial coordinates of the vertices of polyhedral structures - concave antiprisms of second sort. These polyhedra originate from folding the double row strip of equilateral ...
Investigating Composite Polyhedral forms obtained by combining concave cupolae of II sort with Archimedean Solids
(Novi Sad: Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
Concave cupolae of II sort, combined with the other concave or convex polyhedra with at least one matching side, provide many possibilities for the formation of various composite polyhedra. The paper presents research on ...
