Mogućnost rekonstrukcije saobraćajnih nesreća pomoću uređaja za beleženje podataka - pregledni rad / The possibility of traffic accident reconstruction using event data Recorders: A review
(Ekonomski institut, Beograd, 2021)
Uređaji za beleženje podataka koriste se u svrhu istraga saobraćajnih nesreća više od 20 godina. Neke zemlje su zakonski regulisale njihovu primenu i validan su dokaz u istragama i rekonstrukcijama. Međutim, uređaji za ...
Model analysis of bucket wheel excavator SchRs 630 strength
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The possibilities of testing real constructions are often limited, especially in case of large constructions. The idea of model testing is to create a sub-scaled model in order to anticipate the behavior of the real ...
Vickers hardness indentation size effect in selective laser melted MS1 maraging steel
(Sage Publications Ltd, London, 2021)
In this paper, selective laser melting fabricated specimens in non-heat-treated and heat-treated conditions were subjected to Vickers microhardness testing, by using a full range of loadings: 10, 25, 50, 100, 200, 300, ...
Primena Pareto analize u istraživanju bezbednosnih aspekata rada dizalica / Pareto analysis application in research of crane related accidents
(Savez inženjera i tehničara Srbije, Beograd, 2020)
Prethodna istraživanja ukazuju na nedovoljnu istraženost bezbednosnih aspekata rada dizalica. Stoga, prvi cilj ovog istraživanja čine prikupljanje i analiza podataka o akcidentima uzrokovanim radom dizalica, koji su se ...
Fatigue crack growth in a structure exposed to high temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The exhaust nozzle, made of titanium, is the part of a jet engine where the final expansion of the hot gas from the turbine occurs and where the speed of the exhaust gas is further increased to create thrust. During the ...
Faktori sigurnosti u proračunu debljine zida kolona za rektifikaciju / Safety factors in wall thickness calculation of rectification columns
(Vojnotehnički institut, Beograd, 2021)
Kolone za rektifikaciju gasa veoma su važan deo svake fabrike. Njihovi iznenadni otkazi svakodnevno uzrokuju ogromne gubitke, dok curenje tečnosti može biti veoma opasno po ljude i životnu sredinu. Iz tog razloga, pravilan ...
Recent Advances on Hydrogen Embrittlement Understanding and Future Research Framework, Editorial
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Mišljenje učenika srednjih škola u Srbiji o prednostima onlajn učenja tokom pandemije Covid-19 / Mnenie učenikov srednih škol v serbii o preimuŝestvah onlajn-obučeniâ vo vremâ pandemii Covid-19
(Pedagoško društvo Srbije, Beograd i Univerzitet u Beogradu - Filozofski fakultet - Institut za pedagogiju i andragogiju, Beograd, 2020)
Poslednjih godina svedoci smo brojnih istraživanja i pilot-projekata, kako kod nas tako i u svetu, koji se bave ispitivanjem onlajn učenja. U radu se teorijski i empirijski analiziraju mogućnosti onlajn učenja. Teorijski ...
Numerical and Experimental Investigations of Fracture Behaviour of Welded Joints with Multiple Defects
(MDPI, Basel, 2021)
Current standards related to welded joint defects (EN ISO 5817) only consider individual cases (i.e., single defect in a welded joint). The question remains about the behaviour of a welded joint in the simultaneous presence ...
