Modeling the illumination of the church at Studenica monastery during evening services
(Virtual workshop - Artificial Light in Medieval Churches between Byzantium and the West, 2023)
This paper presents an analytical model to analyze illumination of the church interior during the evening service. The focus is on the artificial light achieved using church lighting fixtures known as polycandela, which ...
Stabilnost frekvencije kvarcnih oscilatora
(Друштво за ЕТРАН, Београд и Академска мисао, Београд, 2022)
Oscilatorna kola su neizbežni deo praktično svih
elektronskih uređaja. Najčešće se koriste kola na bazi kvarcnih
kristala. Prikazan je proces proizvodnje i princip rada kvarcnih
oscilatora, kao i podele kristala i ...
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 ...
Nonsingular acyclic matrices with full number of P-vertices
(Linear & Multilinear Algebra, 2013)
We classify the trees for which there is a nonsingular matrix where each vertex is a P-vertex. In particular, we show that such trees have an even number of vertices. Both results provide answers to questions proposed by ...
Note on right zero divisors in the ring of infinite upper triangular matrices over a field
(2017)
A bidiagonal matrix has only two non-zero diagonals. The matrix is called upper bidiagonal if these are the main diagonal and the principal subdiagonal. In this paper we will describe when infinite upper bidiagonal matrices ...
Estimation of thermal impulse response of a multi-layer building wall through in-situ experimental measurements in a dynamic regime with applications
(Elsevier Ltd, 2018)
The dynamic thermal characteristics of the components of a building have a primary influence on the energy performance of the building's envelope under real environmental conditions. In this study, a novel approach for ...
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. ...
Evolution of the wave function of an atom hit by a photon in a three-grating interferometer
(Physica Scripta, 2009)
In 1995, Chapman et al (1995 Phys. Rev. Lett. 75 2783) showed experimentally that the interference contrast in a three-grating atom interferometer does not vanish in the presence of scattering events with photons, as ...
s-nil-čisti prsteni matrica
(VIII simpozijum "Matematika i primene", 11-2017, 2017)
Analiziraju se uslovi pod kojima se matrica nad prstenom može razložiti na zbir idempotentnih i jedne nilpotentne matrice.
