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. ...
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 ...
How does light move?: Determining the flow of light without destroying interference
(Europhysics News, 2013)
Young's two-slit experiment constitutes the paradigm of quantum complementarity. According to the complementarity principle, complementary aspects of quantum systems cannot be measured at the same time by the same experiment. ...
Lossless Compression of Vibration Signals on an Embedded Device Using a TDE Based Predictor
(Kauno Technologijos Universitetas, 2016)
A lossless compression scheme for the data acquired from three-axial microelectromechanical (MEMS) accelerometer is presented. Time delay estimation (TDE) was applied in conjunction with differential pulse code modulation ...
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 ...
Electromagnetic energy flow lines as possible paths of photons
(Physica Scripta, 2009)
Motivated by recent experiments where interference patterns behind a grating are obtained by accumulating single photon events, we provide here an electromagnetic energy flow-line description to explain the emergence of ...
Geometric Proportional Schemas of Serbian Medieval Raška Churches Based on Stambuk's Proportional Canon
(Birkhauser Verlag AG, 2019)
In this paper, an analysis of three Serbian medieval Raška churches highlights the significance of the interaction of regular geometric shapes in the composition of their underlying proportional scheme. The complex geometry ...
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 ...
The resultant of non-commutative polynomials
(Društvo matematičara Srbije, Beograd, 2008)
Let R = K[x; σ] be a skew polynomial ring over a division ring K. Necessary and sufficient condition under which common right factor of two skew polynomials exists is established. It is shown that the existence of common ...
Visualizing properties of a quadratic function using Torricelli’S fountain
(American Association of Physics Teachers, 2020)
In the same chapter of his book Opera geometrica, Torricelli published1 two discoveries: 1) initial velocity of a jet from a container increases with the square root of the depth of the hole¸ 2) he draw the pattern of ...
