SoilGrids250m: Global gridded soil information based on machine learning
(Public Library of Science, 2017)
This paper describes the technical development and accuracy assessment of the most recent and improved version of the SoilGrids system at 250m resolution (June 2016 update). SoilGrids provides global predictions for standard ...
A New Approach in Regression Analysis for Modeling Adsorption Isotherms
(Scientific World Journal, 2014)
Numerous regression approaches to isotherm parameters estimation appear in the literature. The real insight into the proper modeling pattern can be achieved only by testing methods on a very big number of cases. Experimentally, ...
Trace element distribution in surface soils from a coal burning power production area: A case study from the largest power plant site in Serbia
(Catena, 2013)
The content of trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the largest coal-fired power plant in Serbia was determined to assess the contribution of emissions to ...
Static behaviour of bolted shear connectors with mechanical coupler embedded in concrete
(Techno Press, 2018)
The research of shear connectors composed from mechanical couplers with rebar anchors, embedded in concrete, and steel bolts, as a mean of shear transfer in composite connections is presented in the paper. Specific issues ...
Spatial pattern of North Atlantic Oscillation impact on rainfall in Serbia
(Elsevier, 2015)
This study examines the spatial pattern of relationships between annual, seasonal and monthly rainfall in Serbia, and the North Atlantic Oscillation (NAO) for the period of 1961-2009. The first correlation analysis between ...
Free vibration analysis of plate assemblies using the dynamic stiffness method based on the higher order shear deformation theory
(Academic Press, 2016)
This paper deals with the free vibration analysis of isotropic plate assemblies using the dynamic stiffness method (DSM) based on the Reddy's higher-order shear deformation theory (HSDT). Using the proposed method, the ...
Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part I: Theory
(Elsevier Ltd, 2017)
A procedure for developing the dynamic stiffness matrix of a completely free laminated composite plate based on the first-order (FSDT) and higher-order shear deformation theory (HSDT) is presented. The proposed method ...
Some consequences of an inequality on the spectral multiplicity of graphs
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2013)
We present two distinct applications of an inequality relating the multiplicity of an eigenvalue of a graph to a certain subgraph. The first is related to a recent classification, established by Kim and Shader, for the ...
New approach: waste materials as sorbents for arsenic removal from water
(Publication Cover Journal of Environmental Engineering, 2010)
The sorption of inorganic arsenic species arsenite and arsenate from aqueous solutions onto steel-mill waste and waste filter sand, under neutral conditions, was investigated in this study. Additionally, the steel-mill ...
