Organizaciona kultura i unapređenje kvaliteta - razlike između kontinenata / Organizational culture and quality improvement: Differences across continents
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2020)
Prethodna istraživanja pokazuju da organizacioni faktori utiču na programe unapređenja kvaliteta, na način da su performanse preduzeća bolje kada postoji usaglašenost između navedenih faktora. Stoga je cilj ovog rada analiza ...
External atmospheric influences on the mechanical properties of resin-bonded grinding wheels with aluminium oxide and silicon carbide grains
(Institut za ispitivanje materijala, Beograd, 2020)
Ageing effects on resin-bonded grinding wheel properties are presented, including aluminium oxide and silicon carbide influence. Furthermore, humidity is examined as the most likely cause of significant downgrade in ...
Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
Karakteristike procesa sagorevanja nekih vrsta biogoriva u dizel motoru / Combustion characteristics of several types of biofuel in a diesel engine
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2020)
Interesovanje za alternativna goriva koja bi se koristila za pogon motora sus je veoma veliko u čitavom svetu. Zato se istraživanja vezana za ovu problematiku vrše u mnogim vodećim svetskim laboratorijama za motore. Razlog ...
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 ...
Structural integrity assessment of welded bucket-wheel boom
(Institut za ispitivanje materijala, Beograd, 2021)
Research is conducted on the causes of damage and the structural integrity assessment of the bucket-wheel boom welded lattice structures, before and after the repair of vital structures. Additionally, the paper describes ...
Sistem za rano upozoravanje na poplave zasnovan na internetu stvari / IoT based early warning system for torrential floods
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2020)
S obzirom na to da je pretežno planinska zemlja, u Bosni i Hercegovini se povremeno dešavaju elementarne nepogode, pre svega poplave, koje mogu prouzrokovati značajnu materijalnu štetu i ljudske žrtve. Postojeći sistem za ...
