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 ...
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 ...
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 ...
Absolute Time Series GNSS Point Positioning-Data Cleaning and Noise Characterization
(Strojarski fakultet u Slavonskom Brodu, 2020)
Time series data of GNSS point positioning are considerably used for the purpose of geophysical research. The velocity estimates and their uncertainties derive from time series data of GNSS point positioning affected by ...
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 ...
Prototype of the 3D Cadastral System Based on a NoSQL Database and a JavaScript Visualization Application
(2019)
3D cadastral systems are more complex than traditional cadastral systems and they require more complex technical solutions and innovative use of developing technologies. Regarding data integrity and data consistency, 3D ...
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 ...
THE OPTIMAL CONFORMAL PROJECTION FOR PAN-EUROPEAN MAPPING
(Association of Surveyors of Slovenia, 2020)
There is an increasing need for pan-European spatial datasets, mainly to support the common European Union policies. This has inevitably raised demands for adopting pan-European cartographic projections to visualize the ...
