Analysis of the utility and management of karst underground reservoirs: case study of the Perucac karst spring
(Carbonates and Evaporites, 2011)
The construction of an underground dam and reservoir to provide an artificial water storage and karst control groundwater discharge regime is one of the most complex systems of tapping structure in karst. There are not ...
Laboratory investigation of hydraulic characteristics of fly ash as a fill material from the aspects of pollutant transport
(IWA Publishing, 2017)
Depending on the usage of fly ash, it is necessary to determine its environmental parameters, such as the potential for pollutant transport/leaching after its built-in. This study presents a methodology for determination ...
Investigation of accessory elements of representative petrologic radioactivity carriers at Stara Planina, Serbia
(Nuclear Technology and Radiation Protection, 2019)
The present study deals with the abundance of the most common accessory elements of radioactivity carriers on the Stara Planina mountain at four defined locations. All investigated locations have increased radioactivity, ...
Numerical complexity of real-time tracking of objects in defined space by infrared optoelectronic devices
(National Institute of Science Communication and Information Resources (NISCAIR), 2014)
Remote tracking and recognition of various objects in defined space are complex multidisciplinary problems. Depending on selected scene being investigated (object size and dynamics, time needed for data processing and ...
Photodegradation of dimethenamid-p in deionised and ground water
(Savez hemijskih inženjera, Beograd, 2016)
The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals ...
Investigation of cement based composites made with recycled rubber aggregate / Istraživanje kompozita na bazi cementa spravljenih sa recikliranom gumom kao agregatom
(Savez hemijskih inženjera, Beograd, 2012)
The results of experimental investigations performed on cement based composites made with addition of recycled rubber as a partial replacement of natural river aggregate are presented in this paper. Different properties ...
Operator method for calculating q symbols and their relation to weyl-wigner symbols and symplectic tomogram symbols
(Maik Nauka Publishing / Springer SBM, 2014)
We propose a new method for calculating Husimi symbols of operators. In contrast to the standard method, it does not require using the anti-normal-ordering procedure. According to this method, the coordinate and momentum ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Srpsko hemijsko društvo, Beograd, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
Traffic-induced vibrations of frame structures
(Canadian Journal of Civil Engineering, 2013)
Using the spectral element method (SEM), a 2-D numerical model of multi-storey frame structures has been developed. The model has been used to predict traffic-induced vibrations of two, six, and twelve-story concrete ...
Behaviour of electron content in the ionospheric d-region during solar x-ray flares
(Astronomska opservatorija, Beograd i Univerzitet u Beogradu - Matematički fakultet - Odeljenje za astronomiju, Beograd, 2016)
One of the most important parameters in ionospheric plasma research, also having a wide practical application in wireless satellite telecommunications, is the total electron content (TEC) representing the columnal electron ...
