Laminar composite materials damage monitoring by embedded optical fibers
(16th European Conference of Fracture, 2006)
The morphology of cavitation damage of heat-treated medium carbon steel / Morfologija kavitacionog oštećenja srednje-ugljeničnog čelika u poboljšanom stanju
(Serbian Chemical Society, Belgrade, 2006)
In this paper the morphology of the cavitation damage to heat-treated medium carbon steel was analyzed. The experiments were conducted using a modified vibratory cavitation test set up. The erosion rates were measured by ...
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
(Association of Chemical Engineers of Serbia, 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 ...
Influence of electrode materials and the manner of electrode surface processing on gas-filled surge arresters relevant characteristics
(2006 25th International Conference on Microelectronics, MIEL 2006, 2006)
The aim of this paper is to present the electrode effects as approach for the improvement of gas filled surge arresters (GFSA) protective characteristics in the most optimal way. We examined the influence of the electrode ...
Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
Simultaneous correlation of VLE, He and Cpe of some diether + n-alkane systems by the Kohler polynomial / Simultano korelisanje VLE, He i Cpe podataka dietar + n-alkan sistema pomoću Kohlerovog polinoma
(Serbian Chemical Society, Belgrade, 2006)
The simultaneous correlation of VLE and excess properties (HE, cPE) for diether + n-alkane systems was performed in our previous paper by the cubic equation of state which incorporates the activity coefficient model ...
Correlation analysis of IR, H-1 NMR and UV spectral data of alkyl and aryl 4,6-disubstituted-3-cyano-2-pyridones. Part I
(Arkat Usa Inc, Gainesville, 2006)
Spectral characteristics of the two series of previously synthesized and identified 4,6-disubstituted- 3-cyano-2-pyridones were determined, and corresponding H-1 NMR chemical shifts and IR and UV frequencies were correlated ...
New analytical HFET I-V characteristics model
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
In this paper the new analytical model of current - voltage characteristics of a Heterostructure Field Effect Transistor (HFET), is proposed. The model is relatively simple, and at the same time, it describes complex HFET ...
Heat transfer conditions and ultrasonic measurements of alumina based refractories
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
In this paper temperature difference and resistance parameters were used for prediction of thermal shock behavior of alumina based commercial refractories with content of Al2O3 from 28 % to 78 %. Thermal and mechanical ...
Classification of soil samples according to their geographic origin using gamma-ray spectrometry and principal component analysis
(Elsevier Sci Ltd, Oxford, 2006)
A principal component analysis (PCA) was used for classification of soil samples from different locations in Serbia and Montenegro. Based on activities of radionuclides (Ra-226, U-238, U-235, K-40, Cs-134, Cs-131, Th-232 ...
