Reconstruction of the aero-mixture channels of the pulverized coal plant of the 100 MW power plant unit
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
After the last revitalization of thermal power block of 100 MW in TPP 'Kostolac A', made in the year 2004, during the operation of the plant, pulverized coal deposition often occurred in horizontal sections of the aero-mixture ...
The effect of bowl-in-piston geometry layout on fluid flow pattern
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
In this paper some results concerning the evolution of 3-D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from 'omega' to 'simple cylinder' ...
Numerička simulacija uticaja veze na inicijaciju loma kod zavarenih epruveta upotrebom modela lokalnog oštećenja / Numerical simulation of constraint effect on fracture initiation in welded specimens using a local damage model
(Institut za ispitivanje materijala, Beograd, 2011)
U ovom radu, primenjena su dva mikromehanička modela: Gurson-Tvergard-Nidlman (GTN) model i Potpuni Gurson model (CGM) za procenu inicijacije duktilnog loma kod dve različite zavarene epruvete, SE(B) i C(T). Uticaj mismečinga ...
Simultaneous consideration of contingency factors and quality management: An empirical study of Serbian companies
(Academic Journals, Victoria Island, 2011)
The aim of the present paper is to answer whether the QM concept is universal or context-dependent, organic or mechanistic, and theoretical or practical in its essence. The study examines the impact of contingency factors ...
Analysis of local shrinkage patterns of self-adhering and flowable composites using 3D digital image correlation
(Quintessence International, 2011)

Analiza rizika integriteta konstrukcija / Risk analysis in structural integrity
(Institut za ispitivanje materijala, Beograd, 2011)
Prikazana je analiza rizika kao nov pristup rešavanju problema procene integriteta konstrukcija. Opisani su koncepti kontrole zasnovane na rizicima (RBI) i održavanja zasnovanog na pouzdanosti (RCM) sa posebnim osvrtom na ...
Methodology of physical occurrences analogy in researching vehicle lifetime
(Technics Technologies Education Management, 2011)
Lifetime as a critical dimension of the quality of a product is most often studied using the unreliability curve, when there are problems in determining the origin in terms of time limit (Delta t), since monitoring usually ...
