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 ...

Theoretical-experimental determining of cooling time (t8/5) in hard facing of steels for forging dies
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper investigates the accuracy of analytical, empirical, and numerical expressions, i. e. the most favourable methods for calculating the cooling time from 800 to 500°C (t8/5). The degree of accuracy of time t8/5 is ...
Energetic analysis of hard facing and weld cladding of an air powered drop hammer damaged ram
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper studies problems of hard facing of damaged and initially cracked mechanical engineering heavy parts of complex geometry such as large rams of air powered drop hammers. During long-term exploitation, these parts ...
Measurement of local deformation fields in dental composites using 3d optical system
(Chemicke Listy, 2011)
Polymerization shrinkage is the single most important local deformation of dental composites that has a substantial effect on the quality of the tooth-restoration interface in clinical conditions. The aim of this study was ...
