Energy performance of single family houses in Serbia analzsis of calculation procedures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Energy certification of buildings in Serbia was introduced in 2011 and energy label depends on energy need for heating per unit floor area of heated space, calculated by the fully prescribed monthly quasi-steady-state ...
Numerical Modeling of the Porosity Influence on the Elastic Properties of Sintered Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
The effect of structural porosity on the elastic properties of sintered materials was studied using the new multi pore unit cell numerical model - MPUC. Comparison between proposed MPUC model and previously adopted two-phase ...
Distributed hydrological-hydraulic modeling of the karst polje water balance
(Springer Verlag, 2019)
The paper presents developed 3Dnet-HET, a distributed hydrologic model coupled with the discrete channel network concept for groundwater circulation simulation in the karst environment. The hydrologic part is driven by the ...
Radionuclide Immobilization by Sorption onto Waste Concrete and Bricks-Experimental Design Methodology
(Springer International Publishing Ag, Cham, 2019)
The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that ...
