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' ...
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 ...

(Quintessence International, 2011)
Objective: To analyze local shrinkage patterns in terms of surface shrinkage strains and z-axis displacements in a novel self-adhering composite and a conventional flowable composite using three-dimensional digital image ...
Upravljanje rizikom projekata u kompleksnom petrohemijskom sistemu / Project risk management in complex petrochemical system
(Savez hemijskih inženjera, Beograd, 2012)
Istraživanja rizika u složenim industrijskim sistemima, kao i određivanje bitnih faktora koji utiču na odlučivanje i na sprovođenje donetih odluka, pokazala su na primeru savremenog petrohemijskog sistema da se može uspešno ...
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 ...
