Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Soc. for the Advancement of Material and Process Engineering, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
Simulation of transcritical flow in pipe/channel networks
(ASCE - American Society of Civil Engineers, 2004)
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow to all regimes, is an approach that enables efficient numerical ...
Određivanje trajektorije kamena u tekućoj vodi / Determination of a stone particle trajectory in the flowing water
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2002)
U ovom radu prikazana je metodologija proračuna trajektorije kamena u tekućoj vodi. Analizirani su faktori koji utiču na dužinu trajektorije, odnosno na vreme tonjenja i domet ispuštenog zrna. To su: početna dubina sa koje ...
Determination of a Stone particle trajectory in the flowing water / Određivanje trajektorije kamena u tekućoj vodi
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2002)
Trajectory of a stone particle released into the flowing water is determined The length of the particle trajectory, i.e. the duration of sinking and the distance traveled by the released particle, is analyzed in terms of ...
Structural analyses of concrete structures concerning long-term effects / Efekti dugotrajnog opterećenja na ponašanje betonskih konstrukcija
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2008)
Concrete is multi-component material that expresses complex rheological properties, that is viscous-elastic-plastic and aging material. As in statical treatment the linear elastic analyses was preformed in case of concrete ...
Sewer outlets impact on Topciderka river water quality / Uticaj kanalizacionih ispusta na kvalitet vode Topčiderske reke
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
In this paper impact of sewer outlets on water quality of Topciderka river has been presented. Water quality model has been developed as a joint of two standard software packages: HecRAS and QUAL2E. HecRAS, as supporting ...
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 ...
Design of supplementary water tank 'Julino brdo' - Belgrade / Kompenzacioni rezervoar 'Julino brdo' - Beograd
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2004)
The supplementary water tank “Julino Brdo”- Belgrade has been planed in order to provide water supply of the very centre of Belgrade during the accident situations. In the first phase two of the three water tanks are going ...
Fuzzy approach in the uncertainty analysis of the water distribution network of Becej
(Taylor and Francis Ltd., 2006)
One of the most important steps in the development of water distribution system simulation models is providing the dependence of results of simulation on the uncertainty of input values. Information about propagation of ...
