Specific properties of recycled aggregate concrete production technology / Specifičnosti tehnologije spravljanja betona na bazi recikliranog agregata
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
This state-of-the-art paper deals with the differences in production technology of concrete made with recycled aggregate. The properties of recycled aggregate, as a component for new concrete production, are being analyzed ...
Role of upstream planform curvature at asymmetrical river confluences–laboratory experiment revisited
(Kubaba Congress Department and Travel Services, 2008)
River confluence hydrodynamics is influenced by different controls such as the junction angle, bed elevation discordance between incoming streams, upstream planform curvature, momentum ratio values of the confluent streams, ...
DRM-MD approach for bound electron states in semiconductor nano-wires
(Boundary Elements and Other Mesh Reduction Methods Xxix, 2007)
Using the boundary element dual reciprocity method-multi domain (DRM-MD), bound electron states and the corresponding wave functions in semiconductor quantum wires embedded in a matrix were considered. The single circular ...
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 ...
Multiparameter optimization of optical nonlinearities in semiconductor quantum wells by supersymmetric quantum mechanics
(Physics Letters A, 2001)
The multiparameter procedure of semiconductor quantum well profile optimization, using the supersymmetric quantum mechanics, is described and explored. The method generates families of isospectral potentials that depend ...
Pravilne konkavne kupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
The term cupola stands for a polyhedron consisting of two regular polygons: n-gon and 2n-gon in parallel planes, connected by an alternating series of squares and equilateral triangles, ie. Johnsonsolids J3, J4 and J5. ...
Zlatni presek i pravilne konkavne bikupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
Zlatni presek (racio) predstavlja odnos između strane pravilnog pentagona i njegove dijagonale, a takođe se dovodi u vezu sa susednim članovima Fibonacijevog niza. Istraživaem i upoređivanjem metričkih parametara konkavnih ...
Multilayer Plate Finite Element / Konačni element višeslojne laminatne ploče
(Faculty of Civil Engineering of the University of Belgrade─Chair for Technical Mechanics and Theory of structuresGrađevinski fakultet Univerziteta u Beogradu─Katedra za Tehničku mehaniku i teoriju konstrukcija, 2009)
Under the manufacturing and service conditions, laminated composites are exposed to various damage modes, on the local or ply level. As 2D plate models are capable only to determine global behaviour of laminated composites, ...
Concave Regular Faced Cupolae of Second Sort
(Dresden: Technische Universität Dresden; International Society for Geometry and Graphics (ISGG), 2008)
Cupola is a polyhedron which is consisted of two regular polygons: n-gon and 2n-gon in parallel planes, connected by alternating sequence of squares and equilateral triangles, i.e. Johnson’s solids J3, J4 and J5. However, ...
