Mechatronic approach to inventing a novel kind of deformeter
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Stress and strain measurements on frames and structures are mainly conducted by the use of strain gauges. A measuring chain applied in such measurements usually consists of strain gauges, amplifiers and data acquisition ...
Metoda korelacije digitalnih slika u eksperimentalnoj analizi parametara mehanike loma / Digital image correlation method in experimental analysis of fracture mechanics parameters
(Vojnotehnički institut, Beograd, 2017)
U okviru rada su predstavljeni principi i primeri savremenih eksperimentalnih metoda za određivanje parametara mehanike loma. Metodologija analize i određivanja parametara mehanike loma obuhvatila je analizu ponašanja ...
Uključenost zaposlenih kao faktor fleksibilnosti privrednih društava u Republici Srbiji - empirijsko istraživanje / The involvement of employees as a flexibility factor of companies in the Republic of Serbia: Empirical research
(Ekonomski institut, Beograd, 2017)
Adekvatno i pravovremeno reagovanje u uslovima stalnih promena od suštinskog je značaja za opstanak kompanije. Kapacitet za takvo reagovanje se meri stepenom fleksibilnosti pri čemu se pod fleksibilnošću podrazumeva ...

(Emerald Group Publishing Ltd, Bingley, 2017)
Purpose - The purpose of this paper is to analyze sustainability of the constructed projects (Djerdap 1 and 2) and feasibility of the planned ones (Djerdap 3) on the river Danube in the region of Iron Gate, with multi-criteria ...
Experimental determination of brittle fracturing appearance during static indentation of materials based on stone
(Springer Heidelberg, 2017)
During micro cutting process, the presence of both ductile and brittle mode is observed. The appearance of one or the other, or the value of critical penetration depth, when transition is happening, depends on the material ...
Two-dimensional numerical analysis of active flow control by steady blowing along foil suction side by different urans turbulence models
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The effects of active separation control by steady blowing jets were investigated numerically on three different examples: subsonic flow past Aerospatiale A airfoil at 13 degrees angle-of-attack, transonic flow past NACA ...
