Derivation of the Husimi symbols without antinormal ordering, scale transformation and uncertainty relations
(Institute of Physics Publishing, 2015)
We propose a new method for the derivation of Husimi symbols, for operators that are given in the form of products of an arbitrary number of coordinates, and momentum operators, in an arbitrary order. For such an operator, ...
Positive impact of 3D CAD models employment in descriptive geometry education
(Gliwice: PTGiGI, 2019)
Classical Descriptive Geometry (DG) course used 2D drawings for 3D spatial elements representation. Computer graphic introduced simulation of a 3D geometric environment in contemporary DG teaching. Research aim is the ...
A transformational property of the Husimi function and its relation to the Wigner function and symplectic tomograms
(Theoretical and Mathematical Physics, 2011)
We consider the Husimi Q-functions, which are quantum quasiprobability distributions in the phase space, and investigate their transformation properties under a scale transformation (q, p) - gt (lambda q, lambda p). We ...
Contemporary Solutions for 3D Visualisation of a Cultural Heritage Monument
(Central Institute for Conservation ; Scientific Association for the Development and Promotion of New Technologies, Belgrade ; Sopot, 2017)
Recent advances in information technology (IT) solutions opened new possibilities concerning graphic visualization and presentation of existing architectural objects. Cultural heritage objects have specific importance in ...
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 ...
Wireless sensor networks for civil structural monitoring / Primena bežičnih senzorskih mreža u monitoringu građevinskih konstrukcija
(Savez građevinskih inženjera Srbije, Beograd, 2010)
Development of communication technologies during last decade carried out possibility of application wireless sensor networks in many different areas. Recently frequently application of this technology in civil engineering ...
Анализа прстена и модула придруживањем графова / The Analysis of the rings and modules using associated graphs
(Универзитет у Београду, Математички факултет, 2013)
Ova doktorska disertacija prouqava razliqite osobine komutativnihprstena i modula algebarsko kombinatornim metodama. Ako se graf naodgovarajui naqin pridrui prstenu R ili R-modulu M, onda ispitivaem egovih osobina dolazimo ...
The line graph associated to the total graph of a commutative ring
(Ars Combinatoria, 2016)
Let R be a commutative ring with identity and T(Gamma(R)) its total graph. The subject of this article is the investigation of the properties of the corresponding line graph L(T(Gamma(R))). The classification of all ...
The clean graph of a commutative ring
(Charles Babbage Research Centre, 2017)
To gain a better understanding of clean rings and their relatives, the clean graph of a commutative ring with identity is introduced and its various properties established. Further investigation of clean graphs leads to ...
The maximum number of P-vertices of some nonsingular double star matrices
(Elsevier B.V., 2013)
In this short note, we construct a nonsingular matrix A whose graph is a double star of order n >= 4 with n - 2 P-vertices. This example leads to a positive answer, for n >= 6, to a last open question proposed recently by ...
