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.
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, ...
A new characterization of Suškevič's problem on right zero divisors
(X simpozijum "Matematika i primene", 2019)
The description of right zero divisors in that ring is a very di cult problem that has not been resolved yet. We will prove the following characterization: An infinite upper triangular matrix over a field is a right zero ...
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 ...
Toroidality of Intersection Graphs of Ideals of Commutative Rings
(Springer-Verlag Tokyo, 2014)
Let R be a commutative ring with identity and G(R) its intersection graph. In this paper, all toroidal graphs that are intersection graphs are classified. An improvement over the previous results concerning the planarity ...
Relations between scaling-transformed Husimi functions, Wigner functions and symplectic tomograms describing corresponding physical states
(Physica Scripta, 2011)
Husimi Q-functions are the only functions from the class of Cohen quasi-distributions on phase space that after scaling transformation (q, p) - gt (lambda q, lambda p) remain in the same class when the modulus of the scaling ...
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 ...
New pedagogical approaches in digital media - enhanced traffic safety training for children
(University of Niš, Faculty of Occupational Safety, 2018)
According to World Health Organization (WHO) estimates, 186,300 children die annually from road traffic crashes globally, equivalent to over 500 child deaths daily. Road traffic injuries are among the top four global causes ...
Transparent PMMA/silica nanocomposites containing silica nanoparticles coating under supercritical conditions
(Progress in Organic Coatings, 2013)
This work reports the preparation of PMMA/silica nanocomposites with high optical transparency and enhanced mechanical properties using a melt compounding method. The surface of SiO2 particles was modified with a ...
