Optimization of water allocation from a multipurpose reservoir / Efekti primene pravila upravljanja pri raspodeli vode iz višenamenske akumulacije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
The ever increasing water demand in conditions of divergent variability of both natural flows and water requirements can only be met by finding new water sources, combined with the building of new water storage reservoirs. ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
Simulation of transcritical flow in pipe/channel networks
(ASCE - American Society of Civil Engineers, 2004)
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow to all regimes, is an approach that enables efficient numerical ...
Information technology application in construction industry / Primena informacionih tehnologija u građevinarstvu
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2004)
In this paper information technology application in construction industry is analyzed. New technology application gives new possibilities but makes new problems. Main characteristics of construction industry are emphasized ...
Uncertainty reduction in water distribution network modelling using system inflow data
(Urban Water Journal, 2009)
In water distribution network (WDN) modelling, nodal demand is the sum of flows taken by users associated with a computational node. User demands are not fixed in time; rather they are stochastic. Hence, nodal demand is a ...
Separation of water-in-oil emulsions by freeze/thaw method and microwave radiation
(Elsevier, 2006)
In this paper, the demulsification has been achieved with the use of freeze/thaw (F/T) method and microwave radiation (MWR). The object of investigation were emulsion samples prepared by mixing the metal-working-oil, FESOL ...
Structural analyses of concrete structures concerning long-term effects / Efekti dugotrajnog opterećenja na ponašanje betonskih konstrukcija
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2008)
Concrete is multi-component material that expresses complex rheological properties, that is viscous-elastic-plastic and aging material. As in statical treatment the linear elastic analyses was preformed in case of concrete ...
Sewer outlets impact on Topciderka river water quality / Uticaj kanalizacionih ispusta na kvalitet vode Topčiderske reke
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
In this paper impact of sewer outlets on water quality of Topciderka river has been presented. Water quality model has been developed as a joint of two standard software packages: HecRAS and QUAL2E. HecRAS, as supporting ...
Design of supplementary water tank 'Julino brdo' - Belgrade / Kompenzacioni rezervoar 'Julino brdo' - Beograd
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2004)
The supplementary water tank “Julino Brdo”- Belgrade has been planed in order to provide water supply of the very centre of Belgrade during the accident situations. In the first phase two of the three water tanks are going ...
Fuzzy approach in the uncertainty analysis of the water distribution network of Becej
(Taylor and Francis Ltd., 2006)
One of the most important steps in the development of water distribution system simulation models is providing the dependence of results of simulation on the uncertainty of input values. Information about propagation of ...
