Evolution of the wave function of an atom hit by a photon in a three-grating interferometer
(Physica Scripta, 2009)
In 1995, Chapman et al (1995 Phys. Rev. Lett. 75 2783) showed experimentally that the interference contrast in a three-grating atom interferometer does not vanish in the presence of scattering events with photons, as ...
Vibration serviceability of building floors / Stanje upotrebljivosti međuspratnih konstrukcija s obzirom na vibracije
(Savez građevinskih inženjera Srbije, Beograd, 2009)
Satisfaction vibration serviceability of floor structures becomes more important in the case of light-weight and flexible structures. Practically, all modern floor structures are potentially problematic in the sense of ...
Temperature field in roller compacted concrete dams / Temperaturnu polje u gravitacionim branama od valjanog betona
(Savez građevinskih inženjera Srbije, Beograd, 2009)
This paper presents 2D and 3D numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled with actual dam shape, RCC technology and adequate description of ...
Geological Units Classification of Multispectral Images by Using Support Vector Machines
(2009 International Conference On Intelligent Networking and Collaborative Systems (Incos 2009), 2009)
Quantitative techniques for spatial prediction and classification in geological survey are developing rapidly. The recent applications of machine learning techniques confirm possibilities of their application in this field ...
Testing the stability of gps oscillators within Serbian permanent gps stations network
(19th IMEKO World Congress 2009, 2009)
Periodic tests of quartz oscillators incorporated in GPS receivers in Serbia are performed in accredited metrological laboratories by the procedure adopted in metrological laboratory ML160. However, receivers of Serbian ...
Consequences of non planned urban development during turbulent times in Serbia - case study of suburb Kumodraz watershed in Belgrade
(Risk Management of Water Supply and Sanitation Systems, 2009)
Development is usually based oil numerous analyses accounting for planning, economy and population assessments as well as urbanism, architectural and civil engineering infrastructure planning and project design. The modern ...

Paper presents application of long-term Structural Health Monitoring - SHM of the rebuilt TV tower 'Avala'. According the actual trends for improvement of maintenance serviceability, safety and durability, on this structure ...
Polyurethane foam acoustic insulation / Akustička izolacija na bazi poliuretanskih pena
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
Polyurethane based products are often used in civil engineering. Apart to regular use of this material in thermal insulation purposes, polyurethane is widely used in field of acoustic insulation. Usage of modern ...
Univalence and starlikeness of nonlinear transform of certain class of analytic functions
(Proceedings of the Indian Academy of Sciences, 2009)
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
The paper deals with modeling of two phase (water-air) flow in coarse porous medium, where, after reaching some air velocity, instability of the flow occurs. Firstly, a linear stability analysis has been conducted for ...
