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 ...
Hydrogen embrittlement of low carbon structural steel
(Elsevier Science Bv, Amsterdam, 2014)
Hydrogen embrittlement (HE) of steels is extremely interesting topic in many industrial applications, while a predictive physical model still does not exist. A number of studies carried out in the world are unambiguous ...
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 ...

TRIZ methodology provides an opportunity for improving the classical engineering approach based on personal knowledge and experience. This paper presents the application of TRIZ methods for improving vehicle maintenance ...
Primena multivarijantne analize i samo-organizujućih mapa za analizu podatka dobijenih na osnovu opto-magnetnih spektara vode / Multivariate analysis and self organizing feature maps applied for data analysis of opto-magnetic spectra of water
(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 ...
Material characterization of the main steam gate valve made of X20CrMoV 12.1 steel after long term service
(Elsevier Science Bv, Amsterdam, 2014)
Martensitic steel X20CrMo12.1 has been extensively used within the last few decades as a material for tubing systems and pipelines in thermal power plants (TPP). Long term behavior of this steel is very well known and ...
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)
Electromagnetic radiation of all frequencies represents one of the most common and fastest growing environmental influence. All populations are now exposed to varying degrees of electromagnetic radiation and the levels ...
