Mode Analysis of the Optical and the Microwave Waveguides Using Electromagnetic Energy Flow Lines
(Acta Physica Polonica A, 2009)
To better elucidate the essential energy transmission Mechanism in the most common, typical waveguides, the electromagnetic energy flow lines for a planar optical slab waveguide and a microwave rectangular waveguide are ...
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 ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
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 ...
Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Soc. for the Advancement of Material and Process Engineering, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(Materials Science Forum, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
Fatigue damage detection in composite rods using fiber optic intensity based sensors
(Trans Tech Publications Ltd, 2004)
An application of the embedded intensity based fiber optic sensors (FOS) for fatigue damage detection in cantilevered composite rods is presented. During the fatigue test with constant amplitude of oscillations, the ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Advanced Composite Materials, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
