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 ...
On the influence of resonance photon scattering on atom interference
(Physica Scripta, 2010)
Here, the influence of resonance photon-atom scattering on the atom interference pattern at the exit of a three-grating Mach-Zehnder interferometer is studied. It is assumed that the scattering process does not destroy the ...
Boundary element-dual reciprocity formulation for bound electron states in semiconductor quantum wires
(Computer Physics Communications, 2008)
Using the boundary element dual reciprocity method-multi-domain (DRM-MD) a bound electron states and corresponding wave functions in semiconductor quantum wires embedded in a matrix were considered. The single circular and ...
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.
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 ...
Variations of Concave Pyramids of Second Sort with an Even Number of Base Sides
(Bucharest, Romania: SORGING–ROMANIAN SOCIETYFORENGINEERINGGRAPHICSBrasov, Romania: University ‘Transilvania’ of Brasov, 2015)
Concave pyramids of second sort (CP II) are formed similarly to concave cupolae of second sort
(CC II) with a comparable logic of emergence to the regular-faced convex pyramids. They are formed by enclosing the space over ...
Hybrid acrylic nanocomposites with excellent transparency and hardness/toughness balance
(Elsevier, 2020)
The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermomechanical
properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite
since ...
Full quantum mechanical analysis of atomic three-grating Mach-Zehnder interferometry
(Academic Press Inc., 2015)
Atomic three-grating Mach Zehnder interferometry constitutes an important tool to probe fundamental aspects the quantum theory. There is, however, a remarkable gap in the literature betweenthe oversimplified models and ...
Mathematical Principles and Optimal Design Solutions to Compensation for the Pendulum Temperature Dilatation
(Acta Polytechnica Hungarica, 2013)
The paper analyzes the effects of pendulum temperature dilatation on the timepiece running and accounts for the basic mathematical principles that neutralization of these detrimental effects are based upon. Both preliminary ...
Interactive change of lighting in the portrait images
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
We are facing a number of applications for altering portrait photographs using the help of artificial intelligence. Apart from the entertainment purposes, modern computer technologies can also help us get dynamic effects ...
