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 ...
Development and Implementation of Evaluation Framework for Quality Enhancement of Outcome-Based Curriculum
(International Journal of Engineering Education, 2021)
Evaluation to improve teaching and learning is essential for achieving the objectives of higher education programs. While structural and organisational aspects of teaching are frequently assessed, programme evaluation tools ...
Construction cost estimation of reinforced and prestressed concrete bridges using machine learning
(Građevinar, 2021)
Seven state-of-the-art machine learning techniques for estimation of construction
costs of reinforced-concrete and prestressed concrete bridges are investigated in this
paper, including artificial neural networks (ANN) ...
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 ...
Design approach for cost-effective hybrid CLT floors
(Croatian Association of Civil Engineers, 2022)
There is a growing research and production interest for the application of lower-cost
hybrid cross-laminated timber (CLT) panels composed of timber layers of dissimilar quality.
Therefore, an approach for the design of ...
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 ...
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 ...
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 ...
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
(American Institute of Physics Inc., 2019)
