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 ...
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 ...
Modelling extreme values of the total electron content: Case study of Serbia
(Geofizicki Zavod, 2018)
This paper is dedicated to modeling extreme TEC (Total Electron Content) values at the territory of Serbia. For the extreme TEC values, we consider the maximum values from the peak of the 11-year cycle of solar activity ...
Terrain correction computations using digital density model of topographic masses
(Zvava Geodetov Slovenije, 2018)
This paper presents the determination of terrain correction by the means of the Digital Density Model (DDM) of topographic masses (Earth's crust mass above the geoid) for the territory of Serbia. The DDM is determined using ...
Dynamic Soil-Structure Analysis of Tower-Like Structures Using Spectral Elements
(Tehnički vjesnik, 2018)
In this paper general equation system for linear dynamic soil-structure interaction (SSI) in frequency domain is presented. The main objective of the paper is to provide and investigate a possibility to use spectral elements ...
Trajectory-based interpretation of laser light diffraction by a sharp edge
(Springer New York LLC, 2018)
In the diffraction pattern produced by a half-plane sharp edge when it obstructs the passage of a laser beam, two characteristic regions are noticeable. There is a central region, where the diffraction of laser light appears ...
Ex post analysis of road projects: resilience to crisis
(Editorial Board EJTIR, 2018)
This investigation aimed to reveal a mechanism of how different road projects' settings respond to macro-economic crisis. Qualitative and quantitative analyses were performed over a sample of 31 European road projects, in ...
A generalization of nil-clean rings
(Miskolc Mathematical Notes, 2018)
The conditions that allow an element of an associative, unital, not necessarily commutative ring R, to be represented as a sum of (commuting) idempotents and one nilpotent element are analyzed. Some applications to group ...
Simple analysis of daylight saving time effects in Belgrade climate and latitude
(Institute of Architecture and Urban&Spatial Planning of Serbia (IAUS), Belgrade, Serbia, 2018)
Contemporary controversy about daylight saving time (DST) is mainly derived from different standpoints in studies investigating the positive and negative effects of the clock shift during summer period. From the standpoint ...
