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 ...
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 ...
Temperature field in roller compacted concrete dams / Temperaturnu polje u gravitacionim branama od valjanog betona
(Savez građevinskih inženjera Srbije, Beograd, 2009)
This paper presents 2D and 3D numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled with actual dam shape, RCC technology and adequate description of ...
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 ...
Warm-mix asphalt technologies in Europe and USA / Tehnologije asfaltnih mešavina po toplom postupku u Evropi i SAD
(Srpsko društvo za puteve VIA-VITA, Beograd, 2009)
Warm-mix asphalt (WMA) represents the group of technologies that enables reduction of temperatures at which the asphalt mixture is produced and placed. WMA is produced at 20 to 55°C lower temperatures than those typical ...
Demulsification based on the thermal treatment (cooling and heating) of W/O emulsions / Demulzifikacija naizmeničnim hlađenjem i zagrevanjem
(Savez hemijskih inženjera, Beograd, 2004)
An important step in waste water treatment is the removal of oil from an O/W emulsion and the separation of oil and water into two phases, a process usually called demulsification. Modern methods of oil removal from waste ...
Evolution of the wave function of an atom hit by a photon in a three-grating interferometer
(Physica Scripta, 2009)
In 1995, Chapman et al (1995 Phys. Rev. Lett. 75 2783) showed experimentally that the interference contrast in a three-grating atom interferometer does not vanish in the presence of scattering events with photons, as ...
