(Univerzitet u Novom Sadu - Pedagoški fakultet, Sombor, 2021)
Kvalitet nastavnog procesa u velikoj meri zavisi od nastavnika i njihovih kvalifikacija - uloga nastavnika je veoma značajna za uspešnu implementaciju novih nastavnih metoda. Ovaj rad je deo kvantitativne studije ispitivanja ...
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 ...
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 ...

(Elsevier, Amsterdam, 2020)
This paper presents the results and methods used for determining of fracture toughness of reactor steel, denoted as 20MnMoNi55, typically used for structures working at low temperatures, in transition temperature area. In ...
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 ...
Stress Analysis of a Pipeline as a Hydropower Plant Structural Element
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2020)
This paper describes pipeline stress analysis, primarilybranch junctions, as a structural element in hydro-power plants. Pipelines are exposed to internal pressure,which is present under working conditions. Analysis of ...
Kinetic parameters identification of conductive enhanced hot air drying process of food waste
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal ...
Ekonomska opravdanost kabina kranova opremljenih računarskim sistemom vizuelnog navođenja u realnom vremenu / The economic feasibility of crane cabins with real-time computer-aided visual guidance system
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2020)
Brojna istraživanja u oblasti nesreća u kojima učestvuju dizalice ukazuju na činjenice da je rad rukovaoca/kraniste posao visokog rizika i da je uzrok nesreća i nezgoda najčešće ljudski faktor. Shodno tome, inovacije na ...
