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. ...
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 ...
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 ...
Validation and comparison of several global geopotential models with an official quasigeoid solution of Serbia
(Association of Surveyors of Slovenia, 2022)
This study aims to analyze the quality of several local reference
quasigeoid surfaces obtained from several Global Geopotential
Models (GGM) relative to the official quasigeoid solution
of Serbia (SQM2011) and GNSS/dh ...
Tiling the Lateral Surface of the Concave Cupolae of the Second Sort
(Birkhauser Verlag AG, 2019)
As architectural structures, concave cupolae of the second sort (CC II) are suitable for prefabrication, thanks to the uniformity of their elementsregular polygons. This paper discusses ways to subdivide the lateral ...
Short-term forecasting of PM10and PM2.5 concentrations with Facebook's Prophet Model at the Belgrade-Zeleno brdo
(Geofizika, 2023)
We demonstrate the use of Facebook's Prophet (usually just called Prophet) model for short-term air quality forecasting at Belgrade-Zeleno brdo monitoring station. To address missing data, we applied ...
Determination of Mode I fracture properties of European spruce
(Wood Research, 2023)
In this paper an efficient procedure for obtaining a cohesive law for Mode I timber fracture (crack opening), based on the Double Cantilever Beam (DCB) tests is given. DCB tests were performed on ten European spruce specimens ...
Geometrical, Fresnel, and Fraunhofer Regimes of Single-Slit Diffraction

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 ...
