Behaviour of electron content in the ionospheric d-region during solar x-ray flares
(Astronomska opservatorija, Beograd i Univerzitet u Beogradu - Matematički fakultet - Odeljenje za astronomiju, Beograd, 2016)
One of the most important parameters in ionospheric plasma research, also having a wide practical application in wireless satellite telecommunications, is the total electron content (TEC) representing the columnal electron ...
Damage Detection for Civil Structural Health Monitoring Application - A Case Study of the Steel Grid Bridge Structural Model
(Strojarski Facultet, 2018)
The procedure for detecting the location and severity of damage of complex structural systems using their modal properties is an important tool of Structural Health Monitoring (SHM) of civil infrastructure. The herein ...
Laser Interaction with Material - Theory, Experiments and Discrepancies
(Polish Academy of Sciences, 2009)
The experimental treatment of chosen material with laser beams, starting from continuous wave up to fs pulses, produces the necessity to find the common and sophisticated theoretical approaches to interaction modeling. For ...
Variations of total electron content over Serbia during the increased solar activity period in 2013 and 2014
(Zvava Geodetov Slovenije, 2016)
To understand general ionosphere properties over Serbia, an analysis of temporal and spatial ionosphere Total Electron Content (TEC) over the region was performed. The present research focuses on daily, seasonal and spatial ...
Specific features of stainless steel compression elements
(Union of Croatian Civil Engineers and Technicians, 2015)
Stainless steel has a number of features that define different behaviour of structural elements made of this material, as related to equivalent carbon steel elements. These properties, especially prominent in case of ...
Analysis of frame structure vibrations induced by traffic
(Croatian Association of Civil Engineers, 2013)
A simple numerical model for the dynamic analysis of 20 frames in the frequency domain, based on the Spectral Element Method (SEM), is presented in the paper. The influence of soil-structure interaction is taken into ...
Comparison of expert, deterministic and Machine Learning approach for landslide susceptibility assessment in Ljubovija Municipality, Serbia
(Geofizika, 2017)
Landslide Susceptibility Assessment is becoming a very productive re-search area, wherein different modeling approaches are practiced to delineate zones of the high-low likelihood of landslide occurrence. However, ...
Fly ash and slag utilization for the Serbian railway substructure
(Vilnius Gediminas Technical University, 2016)
Approximately 7 million tons of fly ash and slag are produced in thermal power plants in Serbia every year, only 3% of which is used in the cement industry. About 300 million tons of the ash-slag mixture are disposed in ...
Influence of acid treatment and carbonation on the properties of recycled concrete aggregate
(Savez hemijskih inženjera, Beograd, 2018)
Recycled concrete aggregate (RCA), obtained by crushing of original (old) concrete, consists of natural aggregate grains and a cement mortar matrix. The presence of old adhered cement mortar, which has higher porosity than ...
The clean graph of a commutative ring
(Charles Babbage Research Centre, 2017)
To gain a better understanding of clean rings and their relatives, the clean graph of a commutative ring with identity is introduced and its various properties established. Further investigation of clean graphs leads to ...
