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 ...
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 ...
Geometrical, Fresnel, and Fraunhofer Regimes of Single-Slit Diffraction
(American Association of Physics Teachers - AAPT.org, 2019)
Recently, Panuski and Mungan presented the results of their study of light diffraction from a variable-width single slit by observing and measuring the diffraction pattern on an observation screen placed at a fixed distance. ...
Synthesis and performance of polymer based magnetic composite sensing element
(Digest Journal of Nanomaterials and Biostructures, 2015)
The commercial multi-mode optical fiber was coated with magnetic composite material prepared using Nd-Fe-B permanent magnet powder dispersed in poly (ethylene-co-vinyl acetate)-EVA. Characterization of microstructure, ...
Numerical complexity of real-time tracking of objects in defined space by infrared optoelectronic devices
(National Institute of Science Communication and Information Resources (NISCAIR), 2014)
Remote tracking and recognition of various objects in defined space are complex multidisciplinary problems. Depending on selected scene being investigated (object size and dynamics, time needed for data processing and ...
Image positions of a vertical rod in a liquid-filled cylindrical container
(Institute of Physics Publishing, 2014)
We describe a rather simple optical experiment, which many students can easily carry out, but the theoretical explanation of which requires far-from-simple mathematical analysis and application of numerical methods. A thin ...
On the genus of the intersection graph of ideals of a commutative ring
(Journal of Algebra and Its Applications, 2014)
To each commutative ring R one can associate the graph G(R), called the intersection graph of ideals, whose vertices are nontrivial ideals of R. In this paper, we try to establish some connections between commutative ring ...
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 ...
Generalized arago-fresnel laws: the eme-flow-line description
(Journal of Russian Laser Research, 2010)
We study experimentally and theoretically the influence of light polarization on the interference patterns behind a diffracting grating. Different states of polarization and configurations are considered. The experiments ...
