Mode Analysis of the Optical and the Microwave Waveguides Using Electromagnetic Energy Flow Lines
(Acta Physica Polonica A, 2009)
To better elucidate the essential energy transmission Mechanism in the most common, typical waveguides, the electromagnetic energy flow lines for a planar optical slab waveguide and a microwave rectangular waveguide are ...
DRM formulation for axisymmetric laser-material interactions
(WIT Transactions on modelling and simulation, 2006)
The modeling of laser-material interaction using the boundary element dual reciprocity method (BE-DRM) is presented. Thermal effects in the case of cylindrical geometry for mono as well as multi layer structures were ...
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 ...
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 ...
Mehanizmi interakcije lasera sa materijalima
(Savez inženjera i tehničara Srbije, Beograd, 2002)
The paper deals with chosen phenomena connected to laser beam interaction with the material. Particularly, the breakdown thresholds for materials with thermal, dielectric and Brillouin type of the breakdown are considered. ...
On numerical solution of the Schrödinger equation: the shooting method revisited
(Computer Physics Communications, 1995)
An alternative formulation of the "shooting" method for a numerical solution of the Schrödinger equation is described for cases of general asymmetric one-dimensional potential (planar geometry), and spherically symmetric ...
Wireless system for sleeper vibrations measurement
(Communications - Scientific Letters of the University of Zilina, 2014)
This paper describes testing of a wireless technique for measuring the actual sleeper vibrations and determination of their dynamic deflection based on the experimentally acquired acceleration data. Practical measurements ...
The resultant of non-commutative polynomials
(Društvo matematičara Srbije, Beograd, 2008)
Let R = K[x; σ] be a skew polynomial ring over a division ring K. Necessary and sufficient condition under which common right factor of two skew polynomials exists is established. It is shown that the existence of common ...
Influence of femtosecond pulsed laser irradiation on bismuth germanium oxide single crystal properties
(Elsevier Ltd, 2016)
High quality bismuth germanium oxide single crystals were irradiated by a femtosecond pulsed laser beam of increasing power. Analyses performed on irradiated and unirradiated samples showed significant changes in transmittance, ...
Improved upper bound of third order Hankel determinant for Ozaki close-to-convex functions
(Element d.o.o., 2022)
In this paper we improve the upper bound of the third order Hankel determinant for
the class of Ozaki close-to-convex functions. The sharp bound is conjectured.
