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 ...
Geometric Redesign of the Subdivided Surface of CC II: Application In Architecture
(Bucharest, Romania: SORGING–ROMANIAN SOCIETYFORENGINEERINGGRAPHICS, 2019)
The concave polyhedral surface of CC II can be used as a structural template for architectural design of domes, roofs or other covering or stand-alone structures. Subdivision of CC II faces in geometrically defined way can ...
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 ...
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 ...
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 ...
Triangular proportional scheme and concept of the two serbian medieval churches
(Springer Verlag, 2019)
Serbian medieval architectural heritage is notable for its sacred architecture including numerous Christian Orthodox churches built at the territory of former Raška state during the period from the 12th to the 14th centuries. ...
Intensity Fiber-Optic Sensor for Structural Health Monitoring Calibrated by Impact Tester
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this paper, the use of intrinsic intensity fiber-optic sensors for structural health monitoring was investigated. Polyethylene-based composite samples with glass mat reinforcement and embedded telecommunication fibers ...
