Mathematical modeling of the sewage system for improvement of the system and the WWTP in the Maribor city / Matematički model kanalizacionog sistema Maribora radi unapređenja kanalizacionog sistema i rada PPOV-a
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper discuss conditions and constraints for WWTP operation using mathematical modeling of the sewage system for the city of Maribor. Using results of SWMM model accounting for various phases of urban surface runoff ...
Short-term behaviour of reinforced recycled aggregate concrete beams / Ponašanje armiranobetonskih greda od betona na bazi recikliranog agregata pod kratkotrajnim opterećenjem
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
Recycling of waste concrete is one of the sustainable solutions for growing waste disposal crisis and depletion of natural aggregate sources. As a result of that process, recycled aggregate (RCA) is produced and it is used ...
Streamflow measurement by salinity dilution method / Merenje protoka u otvorenim tokovima metodom razblaženja koncentracije soli
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Streamflow measurement often requires a clearly structured measurement reach. Velocity distribution can then be measured using a current meter or by constructing a hydraulic section control (weirs or flumes). However, in ...
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 ...
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 ...
Microstructure and durability related properties of recycled aggregate concrete / Mikrostruktura i trajnost betona sa recikliranim agregatom
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
Aspects of environmental safety, sustainable development, natural resources preservation and proper disposal of construction and demolition waste impose recycling as an important production technology of the construction ...
The Belgrade waste water system during severe rainfall / Beogradski kanalizacioni sistem u uslovima ekstremnih padavina
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The Belgrade waste water system started being built more than 100 years ago. It is getting larger in accordance to urban development aimed at collecting most of waste water including rainfall runoff and communal and ...
Enhancement of digital elevation models for overland flow network delineation in urban catchments / Poboljšanje digitalnog modela terena za delineaciju površinskog tečenja na urbanim slivovima
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
Algorithms to prepare Digital Elevation Models (DMTs) for hydraulic analysis are common practice; these are often called DMT enhancement algorithms, and are frequently the first step of the analysis to extract overland ...
Estimating double side-channel spillway capacity / Procena propusne moći dvostrukog bočnog preliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The capacity of the double side-channel spillway, consisting of the two spillways, with channels joining into a common single branch, is estimated in this paper. For the specific site conditions, such an arrangement may ...
