Some Properties of the Line Graphs Associated to the Total Graph of a Commutative Ring
(Pure and Applied Mathematics Journal, 2014)
Let be a commutative ring with identity and its total graph. The subject of this article is the investigation of the properties of the corresponding line graph In particular, we determine the girth and clique number ...
Wireless system for sleeper vibrations measurement
(Communications - Scientific Letters of the University of Zilina, 2014)
This paper describes testing of a wireless technique for measuring the actual sleeper vibrations and determination of their dynamic deflection based on the experimentally acquired acceleration data. Practical measurements ...
Influence of femtosecond pulsed laser irradiation on bismuth germanium oxide single crystal properties
(Elsevier Ltd, 2016)
High quality bismuth germanium oxide single crystals were irradiated by a femtosecond pulsed laser beam of increasing power. Analyses performed on irradiated and unirradiated samples showed significant changes in transmittance, ...
Negative binomial states for the pseudoharmonic oscillator
(Physica Scripta, 2013)
In this paper we examine some of the statistical properties of the negative binomial states (NBSs) that are a superposition of the number of states with appropriately chosen coefficients, but on the basis of Fock-vectors, ...
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 ...
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 ...
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 ...
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 ...
