(Institut za ispitivanje materijala, Beograd, 2017)
The paper describes the development and manufacturing aspects of the reformer in polymer electrolyte membrane (PEM) fuel cell, from the first step of realization that includes modelling the main parts of the reformer; ...
Fenomen misije u srpskim kompanijama / The phenomenon of mission in Serbian companies
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2019)
Izjava o misiji je personifikacija identiteta organizacije i služi kao osnova za sve zaposlene da se identifikuju sa organizacijom. Dobro definisana misija obezbeđuje stabilnost organizacije jer daje jasan pravac kretanja ...
Expectations, reality and perspectives in using bim for the green building design
(Institut za ispitivanje materijala, Beograd, 2017)
In the late 1970s when the first programs for building energy consumption simulation appeared, architectural practice was based on paper documentation and 2D drafting programs were considered as state of the art technologies. ...

(Institut za ispitivanje materijala, Beograd, 2016)
For the first time after 17 years the Directive 97/23/EC of the European Council and the Council on the harmonisation of the laws of the Member States relating to the making available on the market of pressure equipment ...
Modelling of creep behaviour of a rotating disc in the presence of load and variable thickness by using seth transition theory
(Institut za ispitivanje materijala, Beograd, 2018)
The purpose of this paper is to present study of creep behaviour of a rotating disc in the presence of load and thickness by using Seth's transition theory. It has been observed that a flat rotating disc made of compressible ...
Algoritam za proračun uticaja promene temperature transformatorskog ulja na preciznost lokalizacije parcijalnog pražnjenja čisto akustičkom neiterativnom metodom u energetskom transformatoru / Algorithm for calculating influence of power transformer oil temperature change on the accuracy of allacoustic non-iterative partial discharge localization
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Ovaj rad razmatra čisto akustičku metodu za lokalizaciju parcijalnog pražnjenja u energetskom transformatoru. Ova metoda se zasniva na matematičkom modelu koji koristi multilateraciju, princip vremenske razlike kašnjenja ...
Fatigue life analysis of the integral skin-stringer panel using xfem
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue life of integral skin-stringer panels produced by laser beam welding (LBW) is analysed. This type of panel is used in airframe construction where fatigue and damage tolerance are of paramount importance, since ...
Određivanje vrednosti unutrašnjeg pritiska koji će dovesti do plastične deformacije na modelu račve / Determination of internal pressure value causing pipe branch model to plastically deform
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Složenost geometrije posuda pod pritiskom obično predstavlja uzrok pojave koncentracije napona i deformacija. Savremeni pristup analize stanja napona i deformacija uključuje numerička i eksperimentalna ispitivanja. Svako ...
Istraživanje geometrijskih karakteristika pravozubih konusnih zupčanika sa malim uglom gornjeg konusa bez ozubljenog većeg a sa ozubljenim manjim zupčanikom / Research on geometrical characteristics of straight bevel gears with a small shaft angle with a non-generated gear and generated pinion
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Korišćenjem konusnih zupčanika sa malim uglom precesije gornjeg konusa razvijen je pogon za jedan deo opreme na gas i ulje. Zupčanici se odlikuju visokim stepenom iskorišćenosti (oko 0,9) i malim početnim obrtnim momentom. ...
Wear resistance improvement of thermal plant fan mill impact plates based on numerical flow simulation
(Institut za ispitivanje materijala, Beograd, 2017)
Numerical simulation of 3D multiphase flow is performed to determine the velocity field in the fan mill. The mixture model of the Euler-Euler approach is used. Recirculating gas is a primary phase that carries granular ...
