Fuzzy view of environment / Fuzzy pogled na životno okruženje
(Srpska akademija nauka i umetnosti SANU - Geografski institut 'Jovan Cvijić', Beograd, 2007)
A period of fifty years has been reached since the introduction of the first applications based upon geographical information systems (GIS). GIS has not only influenced the development of methods, collection techniques, ...
Analytical optimization method for water supply systems modeling / Analitička optimizaciona metoda u modeliranju vodovodnih sistema
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
The consequence of an uncertainty of water supply systems models’ parameters is the discrepancy between simulation results and measurement data. The best values of parameters that can be obtained from available measurement ...
Water losses reduction by managing operational pressure / Upravljanje radnim pritiskom u cilju smanjenja gubitaka
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Managing operational pressure is essential for effective reduction of water losses, so system operation is directed towards its maximum reduction with fulfilling the demand of each customer. With this objective, the variable ...
Efficiency of oil removal from real wastewater with different sorbent materials
(Journal of Hazardous Materials, 2007)
The aim of this paper was to investigate the efficiency of different sorbent materials for oil removal from wastewater. Two types of sorbents were investigated: organic (loose natural wool fibers (NWF) and recycled wool ...
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 ...
Application of geostatistics in spatial analyses / Primena geostatistike u prostornim analizama
(Srpsko geografsko društvo, Beograd, 2007)
During the last decade, the development of computational technique has influenced wider implementation of numerical methods in different software applications, which are oriented to processing, presentation, and analysis ...
Ultrasonic flow measurement method: Working principles and use in water distribution and sewer systems / Ultrazvučna merila protoka u sistemima vodovoda i kanalizacije
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Flow metering in Water Supply and Sewer Systems (WSSS) is the essential need Technical reason are the water balance control and the operational management. In the scope of inevitable privatizations (in Serbian environment) ...
Problematika zaštite životne sredine u PD 'Elektrodistribucija Beograd'
(PD "Elektrodistribucija-Beograd", Beograd, 2007)
Zaključak: Zaštiti životne sredine u PD EDB treba posvetiti više pažnje u cilju organizovanja i formalizacije, odnosno potrebno je uvesti procedure ili uputstva za sprovođenje ZŽS. Postojeći kapaciteti za ZŽS u EDB-u su ...
Polynomial interpolation problem for skew polynomials
(Univerzitet u Beogradu - Elektrotehnički fakultet, Beograd i Akademska misao, Beograd, 2007)
Let R = K[x;δ] be a skew polynomial ring over a division ring K. We introduce the notion of derivatives of skew polynomial at scalars. An analogous definition of derivatives of commutative polynomials from K[x] as a function ...
Model generator of water consumption and hydraulic simulation model in water supplying network / Model generator potreba za vodom i hidraulički simulacioni model vodovodne mreže
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Research and development of random sampling procedures in creating model generator of water demand time patterns is shown. Also a composite package combining stochastic nature of water demand and hydrodynamic simulation ...
