Unordered multiplicity lists of wide double paths
(Ars Mathematica Contemporanea, 2013)
Recently, Kim and Shader analyzed the multiplicities of the eigenvalues of a Phi-binary tree. We carry this discussion forward extending their results to a larger family of trees, namely, the wide double path, a tree ...
Trends in the Presence and Roles of Women Physicists in Serbia
(Women in Physics: 3rd Iupap International Conference On Women in Physics, 2009)
In general, the portion of women in physics has been increasing in recent years in Serbia, as well as their presence in research and academic institutions. The percentage of women who earned BSc degrees in physics is greater ...
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 ...
Hankel determinants of the second order for some classes of analytic functions
(Akadémiai Kiadó’s journals, 2021)
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.
Use of Husimi function in time frequency signal analysis / Primena Husimijeve funkcije u vremensko-frekvencijskoj analizi signala
(Savez inženjera i tehničara Srbije, Beograd, 2013)
Husimi function originated in phase space formulation of quantum mechanics. This function appears naturally whenever simultaneous measurement of coordinate and impulse with maximal accuracy allowed by the Heisenberg ...
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 ...
Vibrations measurement using wireless sensor network / Merenje vibracija mrežom bežičnih senzora
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Laboratory prototype of a wireless sensor network (WSN) for vibrations measurements on buildings was developed. The system is comprised of sensor devices (nodes) each having main processor board, accelerometer board, ...
