Traffic safety in road construction zones in the Republic of Serbia
(International Engineering and Technology Institute (IETI), 2023)
Today's times are characterized by increased mobility of people, primarily by road traffic. The number of zones where roadworks are carried out is continuously increasing, so the number of risky situations in which drivers ...
TRANSIENT VAPOUR-LIQUID TWO-PHASE FLOWS IN LARGE VOLUMES OF STEAM GENERATORS
(Serbian Society of Mechanics, 2009)
A numerical method for the simulation and analyses of transient two-phase flows in large volumes on shell sides of steam generators with boiling around tubes in bundles is presented. Modelling of two-phase flow on the ...
Ekvivalentne geometrijske greške obrtnih osa i novi algoritam kompenzacije geometrijskih grešaka neortogonalnoh petoosnih mašina alatki – GECOMP
(Institut Mihajlo Pupin, Univerzitet u BeograduLola Institut, BeogradUniverzitet u Beogradu, Mašinski fakultet, 2022)
Tri translatorne ose imaju ukupno 21 geometrijsku grešku. Svaka obrtna osa mašine alatke ili robota ima šest poziciono zavisnih i četiri poziciono nezavisne geometrijske greške. Ukoliko se merenje ovih grešaka vrši indirektnim ...
Novi pristup identifikaciji strukture površine gumiranog korda korišćenjem laserskog skeniranja visoke rezolucije i multi-rezolucijske analize signala / A new approach to rubberized cord surface structure identification based on high-resolution laser scanning and multiresolution signal processing
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2009)
Gumiranje čeličnog i tekstilnog korda predstavlja jednu od ključnih tehnologija procesiranja gume u proizvodnji auto guma. Tokom ovog procesa koji se izvodi na kalandrima izuzetno je teško ostvariti i držati konstantnom ...

Uticaj ograničenog deformisanja na nastanak žilavog loma korišćenjem kompletnog Gursonovog modela - numerička simulacija / Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2010)
Nastanak žilavog loma u zavarenim spojevima niskolegiranog čelika povišene čvrstoće je predviđen primenom mikromehaničkog kompletnog Gursonovog modela (CGM). Ograničeno deformisanje oko vrha prsline (eng. 'constraint') i ...
Hydro energy potential of cooling water at the thermal power plant
(Društvo termičara Srbije, 2010)
The hydro energy of the gravity water flow from the coal-fired thermal power plant units to the river in an open cooling system of turbine condensers is determined. The water net head duration curve due to the river annual ...
