Supercritical flow in circular pipe bends / Burno tečenje u krivini kružne cevi
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
In this paper a complex flow pattern occurring in a closed conduit bend with supercritical flow is analyzed. The research was done by a scale (physical hydraulic) model, and a numerical model developed in Ansys (Fluent) ...
Application of modified fuzzy TOPSIS method for multicriteria decisions in civil engineering / Primena modifikovanog rasplinutog TOPSIS metoda za višekriterijumske odluke u građevinarstvu
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
In this paper is presented and applied one fuzzy TOPSIS method for the multicriteria ranking of objects for reconstruction and maintenance. At the beginning is given short review on the genesis and development of this ...

(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
This paper statistically investigates the testing results of compressive strength and density of control concrete specimens tested in the Laboratory for materials, Faculty of Civil Engineering, University of Belgrade, ...
Frequency- and time-domain methods related to flutter instability problem / Metode analize flatera u frekventnom i vremenskom domenu
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Bridge flutter phenomenon presents an important criterion of instability, which should be considered in the bridge design phase. This paper presents different bridge flutter methods which can be used to solve the flutter ...
Modelling shape of architectural structure: Elliptic hyperboloid of one sheet
(Institut za arhitekturu i urbanizam Srbije, Beograd, 2014)
The combination of straight lines of constructive elements and curved contours of structural shapes is always challenging in the engineering practice. The 2nd order surface - elliptic hyperboloid of one sheet (ELHY) provides ...
Harmonization of European track quality / Harmonizacija evropskog kvaliteta koloseka
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
This paper deals with characterisation of track geometry, track measuring and recording system, as well as geometric quality levels. The legal framework and state of the art in the field of harmonization of track geometry ...
Properties modeling of cement composites made of fly ash / Modelovanje svojstava maltera primenom elektro-filterskog pepela
(Inženjersko društvo za koroziju, Beograd, 2014)
There is a number of advantages when using fly ash in cement composites. Fly ash is known for decades for its' pozzolanic properties, and thus it is mostly used as an mineral admixture in the process of production of cement. ...
Correlation-regression analysis of modelled chlorine residual's spatial variability in water supply network / Korelaciono-regresiona analiza modelirane prostorne raspodele reziduala hlora u vodovodnoj mreži
(Inženjersko društvo za koroziju, Beograd, 2014)
