Calculating the differences of VTEC values obtained by altimetric and GNSS observations in coastal areas
(SurveyTaylor & Frencis, 2022)
The difference between the VTEC values obtained from the Global Navigation Satellite System
(GNSS) and satellite altimetry is much more noticeable over the ocean and the sea due to less
coverage of the GNSS observations. ...
Impact of precipitation and human activities on suspended sediment transport load in the Velika Morava River Basin (Serbia)
(Arabian Journal of Geosciences, 2022)
Sediment transport time series have shown a severe change in the suspended sediment load transported by the Velika Morava River (Republic of Serbia) during the last few decades. The research objectives of this study were ...
Measuring Chandler Wobble amplitude variations using IERS EOP C04 data
(Astronomska opservatorija i Matematički fakultet - Odeljenje za astronomiju, 2023)
We analyzed the Earth's long-term polar motion using the time series IERS EOP C04 (from 1984 to 2023) to determine the variation of amplitude of the Chandler wobble. To compare the results based on the C04 with the Belgrade ...
Geometrical, Fresnel, and Fraunhofer Regimes of Single-Slit Diffraction

Influence of the solar hydrogen Lya line on the GNSS signal delay in the ionospheric D-region
(Astronomical Institute of the Slovak Academy of Sciences, 2022)
Recent research indicates that the influence of the ionospheric D-region on the propagation of satellite signals cannot be ignored during the intense X-radiation emitted during solar X-ray flares. In this paper, we investigate ...
Stability Calculation of the Plane Steel Frame Structures Using Tangent Modulus Theory
(Hindawi, 2023)
This paper considers the phenomenon of the instability of steel plane frame structures in the elastic-plastic domain. The numerical analysis uses FEM, where the corresponding stiffness matrices are based upon the trigonometric ...
Determination of the Mohr-Coulomb Material Parameters for Concrete under Indirect Tensile Test
(Tehnički vjesnik, 2019)
This paper presents determination of the Mohr-Coulomb material parameters for concrete under indirect tensile testing, design of experiments and numerical simulations. Experiments are designed to control input variables ...
Pressure drop test as a hydroinformatic tool for preliminary network topology validation
(IWA Publishing, 2019)
Usage of the appropriate model of water distribution systems (WDS) enables easier everyday operations and management decisions. Creating a reliable model of WDS requires a large amount of system response data for different ...
Note on Strongly Nil Clean Elements in Rings
(Springer New York LLC, 2019)
Let R be an associative unital ring and let a R be a strongly nil clean element. We introduce a new idea for examining the properties of these elements. This approach allows us to generalize some results on nil clean and ...
Geometric Proportional Schemas of Serbian Medieval Raška Churches Based on Stambuk's Proportional Canon
(Birkhauser Verlag AG, 2019)
In this paper, an analysis of three Serbian medieval Raška churches highlights the significance of the interaction of regular geometric shapes in the composition of their underlying proportional scheme. The complex geometry ...
