The establishment of a new gravity reference frame for Serbia
(Survey Review, 2012)
In this paper, gravimetric work performed in the territory of Serbia is shown chronologically from the end of the nineteenth century until present. The first work, which was based on data from pendulums, is presented ...
Forecasting of THM concentration in distribution water supplying network / Prognoza sadržaja trihalometana u distribucionoj vodovodnoj mreži
(Savez inženjera i tehničara Srbije, Beograd, 2012)
The presence of free chlorine is a prerequisite for the formation of THM's, The THM concentration increases with extending the reaction time between natural organic matter and disinfectants, which means that these products ...
Influence of Boundary Conditions on Nonlinear Response of Laminated Composite Plates / Uticaj graničnih uslova na nelinearan odgovor laminatnih kompozitnih ploča
(University of Montenegro, Faculty of Civil Engineering, 2012)
In this paper the influence of different boundary conditions on geometrically nonlinear response of laminated composite plates is analyzed. Mathematical model, based on layer-wise displacement field of Reddy [1], is ...
Methods of calculating depreciation expenses of construction machinery / Metode proračuna troškova depresijacija građevinskih mašina
(Institut za istraživanja i projektovanja u privredi, Beograd, 2012)
Depreciation expenses represent a significant part of total expenses of construction machinery. Precise calculation of depreciation expenses is often difficult or impossible. Straight line method of depreciation, which is ...
Urban drainage simulation model sensitivity analysis on runoff control elements / Analiza osetljivosti elemenata za kontrolu oticaja u simulacionom modelu kišne kanalizacije urbanog sliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2012)
In current design practice, regardless if classic or sustainable drainage concept approach is applied in modeling of rainfall-runoff process, various drainage elements are used (gullies, catch basins, grates or slotted ...
Prediction model for the cost of road rehabilitation and reconstruction works
(Road and Rail Infrastructure Ii, 2012)
Maintenance of existing road network represents a challenge for public road authorities who seek a balance between available budgets and the need for maintaining level of service at a satisfactory level on existing road ...
Vibrations measurement using wireless sensor network / Merenje vibracija mrežom bežičnih senzora
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Laboratory prototype of a wireless sensor network (WSN) for vibrations measurements on buildings was developed. The system is comprised of sensor devices (nodes) each having main processor board, accelerometer board, ...
Procena vibracija od saobraćaja

Analysis of ground settlement caused by tunnel construction
(Croatian Association of Civil Engineers, 2012)
Prediction of ground settlement is considered as highly significant in the design of tunnels located in urban areas. 2D and 3D modelling of tunnel construction, as needed for settlement analysis, is made according to the ...
Influence of track stiffness on track behaviour under vertical load
(University of Zagreb, Faculty of Transport and Traffic Sciences, 2012)
The analysis of track behaviour under vertical load is traditionally based on the presumption that the stresses and deformations in track elements can be determined by the application of the Winkler's Hypothesis. The rail ...
