Investigation of the behavior of the cable-stayed bridge under test load
(University of Zagreb, Faculty of Science, Department of Geophysics, Andrija Mohorovičić Geophysical Institute, 2011)
A field load testing is an effective method for understanding the behavior and fundamental characteristics of cable-stayed bridges. This paper presents results of the behavior of the reconstructed cable-stayed bridge over ...
Nitrate removal from water by biological denitrification / Biološka denitrifikacija u pripremi vode za piće
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2011)
Ground water pollution by nitrate from routine agricultural practices is a common and growing problem in the major agricultural areas of the world. The concentration of nitrates in these areas may exceed the maximal limited ...
Slab track systems / Konstrukcije koloseka na čvrstoj podlozi
(Savez građevinskih inženjera Srbije, Beograd, 2011)
Slab track systems are in use for more than a hundred years, first as metro and tunnel systems, and today as a standard solution for track systems in urban surroundings and a solution for high-speed lines. The following ...
Assessment of environmental Key Performance Indicators for use in pavement management systems / Ocena ključnih indikatora uticaja na životnu sredinu i njihova primena u sistemima za upravljanje održavanjem kolovoznih konstrukcija
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2011)
Pavement management systems have wide use in the optimization of road maintenance management. The primary criteria for evaluation of different maintenance strategic were mainly economic criteria expressed through either ...
Using ArcGIS for Landslide Umka 3D Visualisation
(Serbian Geological Society, 2011)
The recent developments in earth sciences software are mostly related to the extension allowing
graphical representations of volumes and geological bodies. In this paper, we present a tool for 3D visualization of landslide ...
On the radius and the relation between the total graph of a commutative ring and its extensions
(Srpska akademija nauka i umetnosti SANU - Matematički institut, Beograd, 2011)
We discuss the determination of the radius of the total graph of a commutative ring R in the case when this graph is connected. Typical extensions such as polynomial rings, formal power series, idealization of the R-module ...
Geometrically nonlinear analysis of laminated composite plates using a layer wise displacement model / Gemetrijski nelinearna analiza laminiranih kompozitnih ploča korišćenjem slojevitog modela pomeranja
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2011)
In this paper the geometrically nonlinear laminated finite element model is developed using the principle of virtual displacements (PVD). The 3D elasticity equations are reduced to 2D problem using kinematical assumptions ...
Rail defects due to rolling contact fatigue / Šinski defekti usled zamora materijala
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2011)
Dynamic load on modern railways is increasing with speed, traffic and axle load. Defects due to rolling contact fatigue are becoming more expressed because of high wheel/rail contact stress. Rail grinding removes the ...
Spatial modelling of population concentration using geographically weighted regression method
(Srpska akademija nauka i umetnosti SANU - Geografski institut 'Jovan Cvijić', Beograd, 2011)
This paper presents possibilities of applying the geographically weighted regression method in mapping population change index. During the last decade, this contemporary spatial modeling method has been increasingly used ...
Terrain Surface Modeling Using Triangular Spline Patches
(University of Belgrade - Faculty of Civil Engineering, 2011)
Algorithms and software for digital terrain modeling using TIN based surface model are presented in the paper. Processing of all types of terrain surface data are supported: mass points, local extrema, contours, breaklines, ...
