Concave Pyramids of Second Sort -The Occurrence, Types, Variations
(Faculty of Civil Engineering and Architecture ; Serbian Society for Geometry and Graphics SUGIG, Niš ; Beograd, 2014)
Correspondingly to the method of generating the Concave Cupolae of second sort, the Concave Pyramids of second sort have the similar logic of origination, and their counterpart in regular faced convex pyramids (tetrahedron, ...
Mathematical modelling of ecological processes in reservoirs of hydroenergetic systems / Modeliranje ekoloških procesa u akumulacijama hidroenergetskih sistema
(JP Elektroprivreda Srbije, Beograd, 2009)
Prediction of dynamic changes of water quality in lakes and reservoirs is very important from the aspects of planning and exploitation of hydroenergetic systems. That is the main reason for increasing development of ...
Garantovani protoci nizvodno od brana kao mera zaštite biocenoze
(Jugoslovensko društvo za visoke brane, 2003)
Jedna od ključnih projektnih odluka pri planiranju akumulacija je: koliki garantovani ekološki protok odabrati, kao obavezno ispuštanje iz akumulacije. Na bazi analize metoda koje se koriste u svetu, kao i na bazi hidroloških ...
Effect of bed elevation discordance in the main river on the confluence hydrodynamics in 90 degrees straight-channels' confluences
(CRC Press/Balkema, 2014)
A role of the difference in bed elevations in the main-river (Delta z(MR)) at its entrance to a 90 degrees straight-channels' confluence is studied numerically using a 3D finite-volume model. Three characteristic hydrological ...
Properties Of Self-Compacting Concrete Reinforced With Steel and Synthetic Fibers
(Society for materials and structures testing of Serbia, DIMK, 2011)
Experimental research results of basic physical and mechanical properties of fiber
reinforced self compacting concrete (SFR SCC) are presented in this paper. Besides reference
SCC, two fiber reinforced mixtures were made ...
Metodologija određivanja potrebnih količina voda za vodosnabdevanje naselja za potrebe vodoprivrednih analiza
(Srpsko društvo za zaštitu voda, 2020)
U radu je prikazan pregled korišćene terminologije i metoda za određivanje potrošnje i potrebe za vodom iz vodovoda. Ukazano je prisustvo u praksi i literaturi različitih termina i metoda za obračun i prikazivanje ovih ...
Numerical modelling of glulam beams externally reinforced with CFRP plates
(Vienna University of Technology, 2016)
Timber beams can effectively be reinforced using externally bonded fibre reinforced polymer (FRP) composites. This paper describes a nonlinear 3-dimensional finite element model which was developed in order to accurately ...
Uticaj veličine, rasporeda i položaja blokova umirujućeg bazena stepenastog brzotoka na preostalu energiju
(Srpsko društvo za hidraulička istraživanja i Srpsko društvo za hidrologiju, 2021)
Stepenasti brzotoci su dobri disipatori energije, posebno pri nižim vrednostima jediničnog protoka. Sa povećanjem jediničnog protoka, efikasnost disipacije se smanjuje što rezultuje većom preostalom energijom na ulazu u ...
Flexural behavior of reinforced recycled aggregate concrete beams under short-term loading
(Materials and Structures, 2013)
Recycling of waste concrete is one of the sustainable solutions for the growing waste disposal crisis and depletion of natural aggregate sources. As a result, recycled concrete aggregate (RCA) is produced, and so far it ...
