Spatial variations in the distribution of trace ionic impurities in the water-steam cycle in a thermal power plant based on a multivariate statistical approach
(Central European Journal of Chemistry, 2013)
In this study, a multivariate statistical approach was used to identify the key variables responsible for process water quality in a power plant. The ion species that could cause corrosion in one of the major thermal power ...
Rail inspection of RCF defects
(Croatian Metallurgical Society, 2013)
Rail defects due to rolling contact fatigue (RCF) threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European ...
Numerical modeling of water temperature changes in reservoir Celije / Modeliranje sezonskih promena temperature vode akumulacije Ćelije
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
This paper presents the results of measurements and numerical modeling of water temperature changes in reservoir Celije in the period from April to October 2012. Reservoir Celije on the river Rasina, for many years attracts ...
Design and optimisation of laser scanning for tunnels geometry inspection
(Tunnelling and Underground Space Technology, 2013)
The use of terrestrial laser scanning technology in engineering surveys is gaining an increasing interest due to the very high spatial density of the acquired data. Recent improvements regarding the speed, accuracy, software ...
Transparent PMMA/silica nanocomposites containing silica nanoparticles coating under supercritical conditions
(Progress in Organic Coatings, 2013)
This work reports the preparation of PMMA/silica nanocomposites with high optical transparency and enhanced mechanical properties using a melt compounding method. The surface of SiO2 particles was modified with a ...
Energy loss in a circular-conduit bends with supercritical flow / Gubitak energije u krivini kružnog provodnika pri burnom tečenju
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
In this paper the energy loss in a circular conduit bend with supercritical flow is analyzed. Based on the test results obtained by a scale model, the energy-loss coefficient has been determined. Simple empirical relationships ...
Public-private partnerships in roads and government support: trends in transition and developing economies
(Transportation Planning and Technology, 2013)
Private participation in roads revived strongly in transition and developing countries between 2005 and 2008, growing during the period from US$6.2 billion to US$16.4 billion a year, a new historic peak. However, in view ...
Mapping average annual precipitation in Serbia (1961-1990) by using regression kriging
(Springer-Verlag Wien, 2013)
The appearence of geostatistics and geographical information systems has made it possible to analyze complex spatial patterns of meteorological elements over large areas in the applied climatology. The objective of this ...
Comparison of global geopotential models with Terrestrial gravity data in Libya
(RevCAD Journal of Geodesy and Cadastre, 2013)
This study compares a series of global geopotential models (GGMs) using
available terrestrial data from the territory of Libya. The anomalies of free air were
determined in points of gravimetric survey of Libya by using ...
