Vibration as deciding parameter during revitalization process for replacing the bucket wheel drive
(Jve Int Ltd, Kaunas, 2015)
After years of excavator`s operation in adverse conditions, one can expect a ratio between the bucket wheel drive and bucket wheel boom which may lead to impairment of structural integrity. Finite elements method is defined ...
An analysis of random mechanical failures of bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2015)
In this article random mechanical failures of bucket wheel excavator at open cast mine "Tamnava Zapad" are analysed. Random mechanical failures of mining equipment may represent an important factor in coal production because ...
Zagađenje voda uzrokovano uljima koja potiču od sredstava za čišćenje i odmašćivanje / The degree of water pollution caused by oils from cleaners and degreasers
(Nacionalno naučno društvo za poljoprivrednu tehniku, Novi Sad, 2015)
U nizu tehnoloških procesa kao i za održavanje postrojenja korisie se sredstva za odmašćivanje i čićenje. Najveći deo tih sredstava nakon upotrebe završava u vodama pa moraju biti zadovoljeni uslovi propisani zakonima o ...
Numerical-experimental analysis of the foldable containers strength
(Univ Osijek, Tech Fac, Slavonski Brod, 2015)
This paper describes the numerical and the experimental methodology for analysis of plastic packaging strength characteristics that are representative of its strength in the real life. Numerical analysis was conducted by ...
Water deoxygenation using hollow fiber membrane module with nitrogen as inert gas
(Taylor & Francis Inc, Philadelphia, 2015)
A pilot plant scale fiber membrane system was developed for the removal of dissolved oxygen from water via nitrogen vacuum. Feed water was introduced to the shell side; a nitrogen gas was applied to the lumen side, as an ...
Numerical prediction of processes for clean and efficient combustion of pulverized coal in power plants
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Coal-fired power plant technologies should provide higher efficiency of energy conversion, reduction of pollutants emission, operation of facilities in a wide range of loads and efficient utilization of variable quality ...
Geometry, mechanical and ballistic properties of ADI material perforated plates
(Elsevier Sci Ltd, Oxford, 2015)
In this paper, austempered ductile iron has been evaluated as an alternative to steel for perforated plates applied in the ballistic protection of military vehicles. The austempering was performed in lower and higher ...
Istraživanje novonastalih rizika kod pametnih dizalica - Projekat 'SPRINCE' u programu 'SAF€RA' / Emerging risks in smart process industry cranes survey: SAF€RA research project SPRINCE
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2015)
Savremene teorije fokusirane na istraživanje incidenata pokazuju da smanjenje udela ljudskih grešaka ne može da se postigne isključivo korekcijom ponašanja zaposlenih već zahteva izvesne inovacije koje im mogu pomoći u tom ...
Display probability of symbol errors for MQAM on Rician fading channel based on MGF method
(Univerzitet u Beogradu - Fakultet organizacionih nauka, Beograd, i dr., 2015)
We present a new method for calculating the probability of error per symbol (Symbol Error Probability, SEP) of M-ary Quadrature Amplitude Modulation (MQAM) over a slow, flat, identically independently distributed Rician ...
Actual Diamond Engraving of a Fullerene Coated Glass Plate
(Taylor & Francis Inc, Philadelphia, 2015)
In this paper, we present the results of fullerene film engraving using a diamond tool. Based on available literature data, to our knowledge the fullerene film machinability is not explored in literature. Therefore, we ...
