Diagnostics of bucket wheel excavator discharge boom dynamic performance and its reconstruction
(Polish Academy of Sciences Branch Lublin, 2014)
The paper focuses on an investigation into the possible causes of the bad dynamic performance of bucket wheel excavator C7OOS (BWE) discharge boom in the Kolubara opencast mine, Serbia. A discharge boom load carrying ...
Aerodinamičke karakteristike vozova velikih brzina pod dejstvom bočnih vetrova - numerička analiza koristeći nestacionarni RANS metod / Aerodynamic characteristics of high speed train under turbulent cross winds: A numerical investigation using unsteady-RANS method
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Usled trenda povećanja brzina i smanjenja mase modernih vozova velikih brzina neophodno je razmatrati dejstvo jakih bočnih vetrova na njihovu aerodinamiku. Jaki bočni vetrovi mogu uticati na stabilnost ovih vozova usled ...
Comparative analyses of built environment exposures relevant to health of greenhouse gas emissions reduction strategies in Serbia
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Paper presents comparative analysis of residential indoor air pollutant concentration change over future specified time horizon, implementing building physical and thermal retrofit measures, thus creating pollution mitigation ...
Numerical analysis of thermal stresses in welded joint made of steels x20 and x22
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Stress calculation of steam pipeline is presented, focused on the welded joint. Numerical calculation was peiformed using the finite element method to obtain stress distribution in the welded joint made while replacing the ...

(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Kako bi se došlo do novih saznanja u vezi strukture vode u tečnom stanju, kao i interakcija između rastvorenih materija i molekula vode korišćena je nova metoda bazirana na upotrebi opto-magnetne imidžing spektroskopije ...
Techno-economic optimization of plant for raw ethanol production based on experimental data
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper concerns techno-economic optimization of the production process of raw ethanol in a continuous distillation column as a part of the plant for production of rectified alcohol. Optimization was performed in order ...
Active boundary layer control in linear cascades using CFD and artificial neural networks
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Flow field in linear cascades under high subsonic/transonic conditions has been investigated numerically. Active boundary layer control was employed in the form of sources (jets) distributed across the upper surface of the ...
Fracture mechanics analysis of damaged turbine rotor discs using finite element method
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents evaluation fracture mechanics parameters in low pressure turbine components. Critical locations such as keyway and dovetail area are experiencing stress concentration leading to crack initiation. Stress ...
The combined method for uncertainty evaluation in electromagnetic radiation measurement
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
