Structural monitoring of rebuilt telecommunication tower 'Avala' / Konstrukcijski monitoring obnovljenog telekomunikacionog tornja 'Avala'
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
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 ...
Current activities regarding matching the national reference frame to ETRS of Republic of Serbia and the surrounding countries / Dosadašnje aktivnosti uklapanja postojećih državnih koordinatnih sistema u ETRS Republike Srbije i zemalja u okruženju
(Republički geodetski zavod Srbije, Beograd, 2009)
In the world, as well as us, all the greater use of GPS technology, there is a justified need for the determination of transformation models between existing and new reference system. The paper presents a GPS reference ...
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 ...
Warm-mix asphalt technologies in Europe and USA / Tehnologije asfaltnih mešavina po toplom postupku u Evropi i SAD
(Srpsko društvo za puteve VIA-VITA, Beograd, 2009)
Warm-mix asphalt (WMA) represents the group of technologies that enables reduction of temperatures at which the asphalt mixture is produced and placed. WMA is produced at 20 to 55°C lower temperatures than those typical ...
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 ...
Drainage of bridge decks in urban environment / Odvodnjavanje mostova u urbanim sredinama
(Savez građevinskih inženjera Srbije, Beograd, 2009)
Storm water drainage from buildings, motorways, airports or bridges is a complex task for design engineers. Bridge design deals not only with structural aspects, but with driving safety during heavy rainfall as well. To ...
Electromagnetic energy flow lines as possible paths of photons
(Physica Scripta, 2009)
Motivated by recent experiments where interference patterns behind a grating are obtained by accumulating single photon events, we provide here an electromagnetic energy flow-line description to explain the emergence of ...
Hydro-meteorological data quality assurance and improvement
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
Advances in measurement equipment and data transfer enabled easy and economic automatic monitoring of various hydro-meteorological variables. The main characteristic of such automatic monitoring systems is that they do not ...
Subtle inconsistencies in the straightforward definition of the logarithmic function of annihilation and creation operators and a way to avoid them
(Journal of Physics A-Mathematical and Theoretical, 2009)
Using the resolution of identity spanned by coherent states of the harmonic oscillator, any entire function of the creation and the annihilation operators and its action on a vector in Hilbert space can be defined directly ...
Rationalisation and reliability improvement of fire-fighting systems - the Novi Sad case study
(Urban Water Journal, 2009)
Water supply systems are commonly used to supply fire-fighting water in most EU countries. To provide fast access to water, the standard practice is to install a huge number of hydrants along the entire water supply network. ...
