Istraživanje geometrijskog predznanja studenata prve godine građevinskog fakulteta u Beogradu
(Novi Sad: Fakultet tehničkih nauka, 2006)
Na osnovu testa poznavanja elementarne geometrije koji je sproveden na početku šk. 2004/05 god, sa studentima građevinskog i geodetskog smera Građevinskog fakulteta u Beogradu izvršena je analiza ostvarenih rezultata. ...
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. ...
Zlatni presek i pravilne konkavne bikupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
Zlatni presek (racio) predstavlja odnos između strane pravilnog pentagona i njegove dijagonale, a takođe se dovodi u vezu sa susednim članovima Fibonacijevog niza. Istraživaem i upoređivanjem metričkih parametara konkavnih ...
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 ...
Konstruktivna obrada hiperboličke spirale kao centralne projekcije cilindrične zavojnice
(Novi Sad: Fakultet tehničkih nauka, 2006)
Centralna projekcija cilindrične zavojnice jeste ravna transcedentna kriva, u najopštijem slučaju. U određenim slučajevima, ta kriva će biti upravo spiralna kriva. U specijalnom slučaju, kada se osovina cilindra poklapa ...
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 ...
Laminar composite materials damage monitoring by embedded optical fibers
(Kluwer Academic Publishers, 2006)
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.
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 ...
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 ...
