Non-entire functions of creation and annihilation operators and their relation to phase operator
(Institute of Physics Publishing, 2006)
On the coherent states vertical bar alpha gt any entire function of creation and annihilation operators may be defined. We show that it is not the case for non-entire functions. Use of vertical bar alpha alpha vertical ...
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 ...
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 ...
The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
Način određivanja tangenti u singularnoj tački prostorne krive 4.reda
(Građevinsko arhitektonski fakultet u NišuSrpsko udruženje za geometriju i grafiku, 2008)
Centralna projekcija prostorne krive 4. reda iz njene dvostrukesingularne tačke na ravan je konika-kriva 2. reda. Vrsta konike koja se dobija centralnim projiciranjem zavisi od položaja ravni na koju se vrši projiciranje. ...
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. ...
3D modeling of material heating with the laser beam for cylindrical geometry
(Elsevier Ltd, 2006)
In this work an analytical approach for analyzing heating of material with a laser beam is presented. A thermal model of interaction for the case of cylindrical geometry of the material and asymmetric distribution of the ...
Univalence and starlikeness of nonlinear transform of certain class of analytic functions
(Proceedings of the Indian Academy of Sciences, 2009)
Time-Frequency Analysis of Nonstationary Optical Signals Using Husimi Type Function
(Polish Academy of Sciences, 2009)
Time-frequency analysis is important to identify the localized information of a non-stationary signal in the time and frequency domains simultaneously. There are few different time-frequency analysis methods available with ...
Prevođenje konkavnih kupola druge vrste u tridimenzionalne konstruktivne sisteme – prostorne rešetke
(Niš: Faculty of Architecture and Civil Engineering in Niš; Serbian Society for Geometry and Graphics (SUGIG), 2008)
Cilj istraživanja ovog rada je bio da se iznađu geometrijska rešenja za formiranje prostornih rešetki nad pravilnim poligonalnim osnovama, tako da se postigne prostorna struktura koja ispunjava zahteve rigidnosti datog ...
