FROM WASTE TO RESOURCE: BIOGAS PRODUCTION FROM BLACKWATER THROUGH DECENTRALIZED URBAN PLANNING MODELS
Blackwater, the wastewater stream with the highest sanitary and energy load, is increasingly seen as a resource within circular urban systems. This paper explores its valorization through anaerobic digestion and decentralized planning. Using Banja Luka as a case study, key energy, economic, and spatial thresholds for local treatment feasibility are...

REGIONALIZATION OF CATCHMENTS BASED ON SILHOUETTE WIDTHS FOR FLOOD RESPONSE ESTIMATION ACROSS SERBIA
Regional analysis is often used for flood quantile estimation in ungauged catchments. The regionalization procedure has two phases: the formation of homogeneous regions and flood quantile estimation. The presented research results consider the first phase of the regional analysis for 41 catchments in Serbia. The catchment similarity attributes are ...

TESTING METHODS WITH DIFFERENT DEGREES OF SAMPLING IN DETERMINING SYSTEMATIC INFLUENCES AND MEASUREMENT UNCERTAINTIES OF LINEAR MEASURING DEVICES
This work tested several procedures to determine the linear measuring device's systematic influences and measurement uncertainty. Three methods were developed that differ in the degree and density of sampling during measurement and were compared with the existing method used for calibrating linear measuring devices in the Metrology Laboratory accre...
