SMART MINING: JOINT MODEL FOR PARAMETRIZATION OF COAL EXCAVATION PROCESS BASED ON ARTIFICIAL NEURAL NETWORKS
In the present paper we propose a new artificial neural network model for the estimation of coal cutting resistance and excavator performance as a nonlinear relationship between the examined input (excavator movement angle in the left and right direction, slice height and thickness, coal unit weight, compressive and shear strength) and output facto...

TIME DEPENDENT DEFORMATIONS OF A COUPLED BRIDGE: A CASE STUDY
The bridge's span structure comprises a connected beam designed to support a concrete slab poured over parallel steel supports. Simultaneously, segmental construction, shrinkage, and the flow of concrete play a significant role in stress redistribution over time. The span construction is statically indeterminate due to its connections with the abut...

ANALYSIS, COST ESTIMATION AND OPTIMIZATION OF REINFORCED CONCRETE SLAB STRENGTHENING BY STEEL AND CFRP STRIPS
As a result of the planned change of use, the imposed load on the existing reinforced concrete mezzanine slab will be significantly increased, wherefore a diagnostics and assessment of the current state of the structure has been carried out. The control calculation showed that the slab does not have sufficient bearing capacity for the increased loa...

CONTROL FACTORS OF IRON MINERALIZATION IN THE METALLOGENY OF THE LJUBIJA ORE REGION
The control factors of mineralization in the Ljubija ore region are stratigraphic, lithological, magmatogenic, structural-tectonic and hypergenic. The distribution of iron ores in the Ljubija ore region is primarily controlled by the spread of the Olistostrome member of the Carboniferous Javorik flysch formation. Only that member, whether uncovered...

SIGNIFICANCE OF HARVEST RESIDUES IN SUSTAINABLE MANAGEMENT OF ARABLE LAND I. DECOMPOSITION OF HARVEST RESIDUES
Harvest residues are parts of cultivated plants that remain on the plot after harvest or grazing. Decomposition of plant residues by microorganisms involves two simultaneous processes: mineralization and humification of carbon compounds. Decomposition processes depend on the type of plant residues, edaphic factors and residue management factors. Ed...
