Managing rail service life
(Croatian Metallurgical Society, 2014)
The service life Of tails depends especially on the operational loads and speeds on the railway lines; as well as on the rail maintenance policy. There are multiple aspects of rail maintenance optimization. The following ...
Mechanical and time-dependent properties of high-volume fly ash concrete for structural use
(ICE Publishing, 2016)
A two-phase experimental study on the effect of simultaneous partial replacement of cement and fine aggregate with fly ash on the mechanical and time-dependent properties of high-volume fly ash concrete (HVFAC) is presented. ...
Shrinkage of recycled aggregate concrete: experimental database and application of fib Model Code 2010
(Springer Netherlands, 2018)
This paper describes a meta-analysis of previously published studies on the shrinkage strain of recycled aggregate concrete (RAC). The study aims at providing an analytic expression for the shrinkage strain of RAC to be ...
Machine Learning Techniques for Modelling Short Term Land-Use Change
(MDPI AG, 2017)
The representation of land use change (LUC) is often achieved by using data-driven methods that include machine learning (ML) techniques. The main objectives of this research study are to implement three ML techniques, ...
Mapping average annual precipitation in Serbia (1961-1990) by using regression kriging
(Springer-Verlag Wien, 2013)
The appearence of geostatistics and geographical information systems has made it possible to analyze complex spatial patterns of meteorological elements over large areas in the applied climatology. The objective of this ...
Rail inspection of RCF defects
(Croatian Metallurgical Society, 2013)
Rail defects due to rolling contact fatigue (RCF) threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European ...
Improved input to distributed hydrologic model in areas with sparse subdaily rainfall data using multivariate daily rainfall disaggregation
(Journal of Hydroinformatics, 2018)
Flood forecasting relies on good quality of observed and forecasted rainfall. In Serbia, the recording rain gauge network is sparse and rainfall data mainly come from dense non-recording rain gauges. This is not beneficial ...
Estimating the Performance of Random Forest versus Multiple Regression for Predicting Prices of the Apartments
(MDPI AG, 2018)
The goal of this study is to analyse the predictive performance of the random forest machine learning technique in comparison to commonly used hedonic models based on multiple regression for the prediction of apartment ...
Numerical modeling of hypolimnetic oxygenation by electrolysis of water
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The paper presents a novel method for hypolimnetic oxygenation by electrolysis of water. The performance of the method is investigated by the laboratory and the field experiment. The laboratory experiment is conducted in ...
Haplotype variation in the Physa acuta group (Basommatophora): genetic diversity and distribution in Serbia
(Hellenic Centre for Marine Research, 2016)
The genus Physa (= Physella) includes the most abundant and diverse freshwater gastropods native to North America. Due to their invasive nature, many species occur throughout the world. The most abundant species, Physa ...
