Improvement and modification of the energy-dispersive X-ray fluorescence method for the determination of metal elements in cement leachates - A chemometric approach
(Srpsko hemijsko društvo, Beograd, 2020)
A modification of an analytical procedure for the energy-dispersive X-ray fluorescence (EDXRF) quantification of ten chemical elements (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb and Zn) in the leachates obtained from cement binders ...
Prediction model based on artificial neural network for pyrophyllite mechano-chemical activation as an integral step in production of cement binders
(Elsevier Sci Ltd, Oxford, 2020)
The optimal outputs of pyrophyllite mechano-chemical activation in an ultra-centrifugal mill performing under different technological conditions were determined by analytical modeling and verified via Artificial Neural ...

Model of Probabilistic Analysis of Pile Capacity Based on the Extrapolation of Load-Settlement Curves
(Springer, New York, 2020)
This paper formulates a mathematical model using the extrapolation of load-settlement curves with a rational function for analyzing the capacity of piles obtained from the static load test (SLT). In preliminary analyses, ...
Has the latest global financial crisis changed the way road public-private partnerships are funded? A comparison of Europe and Latin America
(Elsevier Sci Ltd, Oxford, 2020)
A financial/economic crisis may have an adverse effect on transport public-private partnerships (PPPs) as both traffic demand is negatively influenced, and governments are further under pressure. However, research on awarded ...
Determination of the Pile Stiffness Matrix Based on the Pile Load Test Results and the Effect of Pile Interaction
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
The paper presents the determination of the elements of the pile stiffness matrix based on pile load test results, made for the needs of modernization of oil refinery for NIS in Pancevo. The tests were carried out on CFA ...
Deflection Calculation for Beam-type Structures from Measured Strain Data
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Behavior of structures under various load types is determined by their deformation characteristics, global deformation characteristics - deflections and rotations, and local deformation characteristics - strains / stresses ...
