Quantum operators in Weyl quantization procedure via Wigner representation of quantum mechanics - quantum phase operator as a special case
(Wiley-VCH Verlag, 2003)
Coherent states, in Wigner representation of quantum mechanics which is classical in structure with Wigner function playing the role of classical phase space probability distribution, and standard quantum mechanical ...
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 ...
Subtle inconsistencies in the straightforward definition of the logarithmic function of annihilation and creation operators and a way to avoid them
(Journal of Physics A-Mathematical and Theoretical, 2009)
Using the resolution of identity spanned by coherent states of the harmonic oscillator, any entire function of the creation and the annihilation operators and its action on a vector in Hilbert space can be defined directly ...
Electromagnetic energy flow lines as possible paths of photons
(Physica Scripta, 2009)
Motivated by recent experiments where interference patterns behind a grating are obtained by accumulating single photon events, we provide here an electromagnetic energy flow-line description to explain the emergence of ...
Damage monitoring of composite laminates by means of intensity based fiberoptic sensors / Praćenje oštećenja kompozitnih laminata pomoću fiberoptičkih senzora intenzitetnog tipa
(Institut za ispitivanje materijala, Beograd, 2005)
The paper deals with the research in applying optical fibres (OF) as intensity-based sensors in real-time damage detection of laminar composite materials. For experimental purposes, thermoplastic laminar composite materials ...
Interaction of lasers of various types with alloys based on Ni and Ti / Interakcija različitih tipova lasera sa legurama baziranim na niklu i titanijumu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2008)
Commonly implemented nickel and titanium alloys are nowadays alloyed with many new elements. Obtained in this way, new Ti-alloys are of great practical significance in aircraft industry, while Ni-alloys are important in ...
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 ...
Starlike and close-to-convexfunctions defined by differential inequalities
(Elsevier, 2009)
We present new sufficient conditions for an analytic function to be close-to-convex and
starlike, respectively. These conditions are easy to apply and can be used to obtain functions
in these classes.
Behavior of smart ballistic composite materials: Comparisons experimental results with numerical simulations / Analiza ponašanja smart balističkih kompozita - poređenje eksperimentalnih rezultata i numeričke simulacije
(Visoka tehnička škola strukovnih studija, Beograd, 2004)
The object of this paper is exploration of application of optical fibers as intensity-based sensors in real-time damage detection in laminate composite materials, and discussion of loading transfer mechanisms through ...
Polynomial interpolation problem for skew polynomials
(Univerzitet u Beogradu - Elektrotehnički fakultet, Beograd i Akademska misao, Beograd, 2007)
Let R = K[x;δ] be a skew polynomial ring over a division ring K. We introduce the notion of derivatives of skew polynomial at scalars. An analogous definition of derivatives of commutative polynomials from K[x] as a function ...
