Operator method for calculating q symbols and their relation to weyl-wigner symbols and symplectic tomogram symbols
(Maik Nauka Publishing / Springer SBM, 2014)
We propose a new method for calculating Husimi symbols of operators. In contrast to the standard method, it does not require using the anti-normal-ordering procedure. According to this method, the coordinate and momentum ...
Image positions of a vertical rod in a liquid-filled cylindrical container
(Institute of Physics Publishing, 2014)
We describe a rather simple optical experiment, which many students can easily carry out, but the theoretical explanation of which requires far-from-simple mathematical analysis and application of numerical methods. A thin ...
Numerical complexity of real-time tracking of objects in defined space by infrared optoelectronic devices
(National Institute of Science Communication and Information Resources (NISCAIR), 2014)
Remote tracking and recognition of various objects in defined space are complex multidisciplinary problems. Depending on selected scene being investigated (object size and dynamics, time needed for data processing and ...
On the genus of the intersection graph of ideals of a commutative ring
(Journal of Algebra and Its Applications, 2014)
To each commutative ring R one can associate the graph G(R), called the intersection graph of ideals, whose vertices are nontrivial ideals of R. In this paper, we try to establish some connections between commutative ring ...
On dinamic spiral patterns - polygonal frames inscribed in circular sections of quadric surfaces
(Faculty of Civil Engineering and Architecture in Niš ; Serbian Society for Geometry and Graphics, Niš ; Beograd, 2014)
Spiral forms, nowadays actual, especially in the area of architecture and design, were the inspiration point for an creative geometrical research. Acquainted with different approaches, present in practical and theoretical ...
Toroidality of Intersection Graphs of Ideals of Commutative Rings
(Springer-Verlag Tokyo, 2014)
Let R be a commutative ring with identity and G(R) its intersection graph. In this paper, all toroidal graphs that are intersection graphs are classified. An improvement over the previous results concerning the planarity ...
Some Properties of the Line Graphs Associated to the Total Graph of a Commutative Ring
(Pure and Applied Mathematics Journal, 2014)
Let be a commutative ring with identity and its total graph. The subject of this article is the investigation of the properties of the corresponding line graph In particular, we determine the girth and clique number ...
On the role of circular sections of quadric surfaces
(Innsbruck University Press, Innsbruck, 2014)
As a part of new advanced course curriculum of Descriptive geometry, in the Faculty of Civil engineering, creative 3D modeling of specific structures is included. These structures, inspired by contemporary architecture ...
Measurement of Sleepers Vibrations and Determination of Their Dynamic Deflection and Train Velocity / Merenje vibracija pružnih pragova i određivanje njihovog dinamičkog ugiba i brzine vozova
(Elektrotehnički fakultet, Istočno Sarajevo, 2014)
Rail defects head checking on the Serbian railways
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2014)
The rail defects due to rolling contact fatigue represent serious safety hazard for rail traffic all around the world. That hazard is more distinct on railways without adequate maintenance strategy, with the increase of ...
