Study of the influence of channel geometry and hydraulic resistance on flow characteristics in compound channels with the exchange discharge method / Primena modela razmene količine kretanja u analizi uticaja geometrije i hidrauličkih otpora na osnovne odlike tečenja u koritu za veliku vodu
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
A series of numerical experiments is conducted to determine how compound channel geometry and floodplain roughness affect both a momentum transfer between main channel and floodplains and its contribution to the total ...

An application of Groebner bases to planarity of intersection of surfaces
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2009)
In this paper we use Groebner bases theory in order to determine planarity of intersections of two algebraic surfaces in R3. We specially considered plane sections of certain type of conoid which has a cubic egg curve as ...
Mechanical properties of recycled aggregate concrete / Mehaničke karakteristike betona na bazi recikliranog agregata
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
For the purpose of the environmental preservation and sustainable development, production of concrete made of recycled concrete rubble (recycled aggregate concrete-RAC) become more often. Results of experimental investigations ...
Calibrating and validating a FE model for long-term behavior of RC beams / Kalibracija i verifikacija modela konačnih elemenata za dugotrajno ponašanje AB greda
(Savez inženjera i tehničara Srbije, Beograd, 2014)
This study presents the research carried out in finding an optimal finite element (FE) model for calculating the long-term behavior of reinforced concrete (RC) beams. A multi-purpose finite element software DIANA was used. ...
Flow measurement at the short structures in hydraulic complex conditions: HE 'Djerdap 2' case study / Merenje protoka na kratkim objektima u hidraulički neregularnim uslovima na primeru HE 'Đerdap 2'
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Hydraulic conditions at short structures in most cases prevents the existence of cross sections with parallel streamlines and fully developed turbulent flow profile. In such conditions the flow measurement is rather ...
Usage of zinc-silicate coatings in friction connections / Primena cink-silikatnih premaza u tarnim spojevima
(Institut za istraživanja i projektovanja u privredi, Beograd, 2016)
Usage of zinc-silicate coatings as anti-corrosive protection of friction connections results in reduction of construction time and provides protection from corrosion. Such protection system has a number of advantages in ...
Primena grejnih kablova u izvođenju betonskih radova pri ekstremno niskim temperaturama sa numeričkim primerima
(Udruženje inženjera građevinarstva geotehnike arhitekture i urbanista, 2021)
Očvršćavanje betona u uslovima niskih temperatura dovodi do usporavanja procesa
hidratacije cementa. U ekstremnim uslovima može doći do prekidanja hidratacije cementa i
pojave smrzavanja vode u betonu. Sve to može dovesti ...
The pressurized pipelines: The risk of bidirectional fluid exchange with the environment / Cevovodi pod pritiskom i rizik od razmene fluida sa okolinom
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The pressurized pipeline fluid transport is supposed to be cheap, reliable and efficient. If buried, pipelines are hard observable by means of leaks, minor cracks and asset damages. These phenomena can influence both the ...
Rešavanje jednačina kretanja fluida metodom zasnovanom na praćenju fluidnih delića (SPH metoda) / SPH Method
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2014)
U ovom radu se opisuje numerička metoda za rešavanje jednačina kretanja fluida zasnovana na praćenju fluidnih delića, koja se na engleskom jeziku naziva Smoothed Particle Hydrodynamics (skraćeno SPH). Predstavljene su ...
