Laminar composite materials damage monitoring by embedded optical fibers
(Kluwer Academic Publishers, 2006)
Energy distribution of X-rays reflected from a half space in double collision approximation
(Elsevier Ltd, 2006)
The results obtained in a Monte Carlo simulation of X-ray reflection from water show that for energies up to 20 keV, single and double reflected photons absolutely dominate. Analyzing in detail geometry of the collisions ...
DRM formulation for axisymmetric laser-material interactions
(WIT Transactions on modelling and simulation, 2006)
The modeling of laser-material interaction using the boundary element dual reciprocity method (BE-DRM) is presented. Thermal effects in the case of cylindrical geometry for mono as well as multi layer structures were ...
Non-entire functions of creation and annihilation operators and their relation to phase operator
(Institute of Physics Publishing, 2006)
On the coherent states vertical bar alpha gt any entire function of creation and annihilation operators may be defined. We show that it is not the case for non-entire functions. Use of vertical bar alpha alpha vertical ...
3D modeling of material heating with the laser beam for cylindrical geometry
(Elsevier Ltd, 2006)
In this work an analytical approach for analyzing heating of material with a laser beam is presented. A thermal model of interaction for the case of cylindrical geometry of the material and asymmetric distribution of the ...
The usage of optical fibers for damage detection in ballistic protection composite laminates / Upotreba optičkih vlakana za detekciju oštećenja kompozitnih laminata namenjenih za balističku zaštitu
(Savez hemijskih inženjera, Beograd, 2006)
This paper describes the procedure of embedding fiber optic sensors in laminar thermoplastic composite material, as well as damage investigation after ballistic loading. Thermoplastic-reinforced composite materials were ...
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.
Damage detection in laminar thermoplastic composite materials by means of embedded optical fibers / Detektovanje oštećenja u laminarnim termoplastičnim kompozitnim materijalima korišćenjem ugrađenih optičkih vlakana
(Savez hemijskih inženjera, Beograd, 2006)
This paper investigates the possibility of applying optical fibers as sensors for investigating low energy impact damage in laminar thermoplastic composite materials, in real time. Impact toughness testing by a Charpy ...

Pravilne konkavne kupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
The term cupola stands for a polyhedron consisting of two regular polygons: n-gon and 2n-gon in parallel planes, connected by an alternating series of squares and equilateral triangles, ie. Johnsonsolids J3, J4 and J5. ...
