Height anomalies determined by three different GOCO models
(International Multidisciplinary Scientific GeoConference-SGEM, 2019)
This paperwork is dedicated to the research of the quality of height anomalies derived from the Global Geopotential Models GOCO over the Serbia territory. Three different types of approaches for the same model were considered: ...
Numerical study of vibrations induced by horizontal-axis wind turbine on a steel building
(Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2019)
One of the most important acceptance issues regarding the implementation of small-scale wind turbines in urban environments is related to human comfort. Turbine-induced vibrations can have a large influence on small-scale ...
Image Processing for Hydraulic Jump Free-Surface Detection
(IAHR, 2019)
Hydraulic jumps exhibit a high degree of free-surface oscillations, triggered by intense turbulence and aeration.
These processes are difficult to model numerically and are frequently investigated on a scale model. ...
Geometric Redesign of the Subdivided Surface of CC II: Application In Architecture
(Bucharest, Romania: SORGING–ROMANIAN SOCIETYFORENGINEERINGGRAPHICS, 2019)
The concave polyhedral surface of CC II can be used as a structural template for architectural design of domes, roofs or other covering or stand-alone structures. Subdivision of CC II faces in geometrically defined way can ...
On a generalized Jordan normal form of an infinite upper triangular matrix
(Taylor & Francis Ltd, United Kingdom, 2019)
Any square matrix over an algebraically closed field has a Jordan normal form. In this paper, we prove that every infinite upper triangular matrix over an arbitrary field has a generalized infinite Jordan normal form.
GNSS and SAR Signal Delay in Perturbed Ionospheric D-Region During Solar X-Ray Flares
(IEEE (Institute of Electrical and Electronics Engineers), 2019)
We investigate the influence of the perturbed (by a solar X-ray flare) ionospheric D-region on the GNSS and SAR signals. We calculate a signal delay in the D-region based on the low ionospheric monitoring by very low ...
Coupled groundwater hydrodynamic and pollution transport modelling using Cellular Automata approach
(Journal of Hydrology, 2019)
High urbanization puts many groundwater resources at risk of quality deterioration. Analyzing all viable potential groundwater contamination scenarios for good decision making requires reliable tool. Coupling several complex ...
Impact of CO2 Emissions on Low Volume Road Maintenance Policy: Case Study of Serbia
(National Academy of Sciences, Transportation Research BoardSAGE Publications, 2019)
About 20% of the Serbian national road network has sections with low volume traffic. These sections are maintained in relatively poor condition since the maintenance budget is typically allocated to the road sections with ...
Fatigue Resistance of a Grid-Reinforced Asphalt Concrete using Four Point Bending Beam Test
(CRC Press/Balkema, 2019)
This paper presents an experimental study of the influence of a reinforcement system on fatigue resistance of asphalt concrete. For purpose of this research, unreinforced and grid-reinforced asphalt specimens were tested. ...
Influence of Loading Cracks on the Carbonation Resistance of RC elements
(Elsevier, 2019)
In reinforced concrete (RC) structures, carbonation induced corrosion is one of the most significant durability issues. A very important factor that affects the carbonation process is the appearance of cracks in RC structures. ...
