Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
Visual performance research of call centre VDT operators
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2004)
This paper considers different factors related to the visual functions of the VDT operators. The visual performance of the call centre VDT operators is analyzed. For that purpose, the checklists for the human - computer ...
Uticaj zaštitnih struktura traktora na povećanje bezbednosti rukovalaca u eksploataciji / The influence of tractor's roll-over protective structure to increased safety of operators in exploitation
(Institut za istraživanja i projektovanja u privredi, Beograd, 2004)
Bezbednosni parametri u eksploataciji traktora imaju veoma veliki značaj Jedan od najznačajnijih elemenata koji utiču na bezbednost rukovalaca u eksploataciji traktora su zaštitne strukture i kabine. U zavisnosti od vrste, ...

U radu je dat proračun i eksperimentalna analiza naponskog stanja noseće strukture vagona za prevoz automobila. Proračunom je obuhvaćena statička i dinamička analiza noseće strukture, kao i određivanje torzione krutosti ...
Group theoretical formulation of quadrilateral and hexahedral isoparametric finite elements
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
The group supermatrix procedure, developed by Zlokovic, is applied for derivation of stiffness matrices of quadrilateral and hexahedral isoparametric finite elements using the symmetry groups C-2v and D-2h respectively. ...
Optimal SIR-based power updates in wireless CDMA communication systems
(IEEE, New York, 2004)
In this paper we present two new control algorithms that potentially can be used as efficient techniques for power updates in wireless CDMA communication networks. The algorithms are obtained by optimizing the signal-to- ...
Mobilna balans-mašina - novi koncept u industrijskoj primeni / Portable balancing machine: A new concept in the industrial application
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2004)
Niz masivnih i glomaznih rotora predstavlja ozbiljan tehnički izazov za kvalitetno i bezbedno uravnotežavanje. Jedna od opcija je da se nakon kapitalnog servisa rotori parnih Hi gasnih turbina odnosno generatora transportuju ...
Gibbson: Peptide plane as a unique biological nanostructure
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper we describe the properties of peptide plane of amino acids from a biophysical point of view. We use Lagrange's equations to calculate the energy states of peptide plain and to explain its biophysical proper-ties. ...
Microstructure and toughness of CuNiMo austempered ductile iron
(Elsevier, Amsterdam, 2004)
The effect of austempering on the microstructure and toughness of nodular cast iron (designated as CuNiMoSG) alloyed with molybdenum, copper, nickel, and manganese has been studied. Light microscopy (LM), scanning electron ...
Dobijanje alata za presovanje, brizganje i duvanje plastičnih masa, gume i keramike postupkom elektroformiranja / Electroforming fabrication of tools for pressing and blow moulding plastic, rubber and ceramic materials
(Inženjersko društvo za koroziju, Beograd, 2004)
U ovom radu je opisana tehnologija elektroformiranja za dobijanje alata sa kopija orginalnog predmeta. Na ovaj način je zaštitićen orginalni predmet od oštećenja s obzirom da se samo jednom sa njega uzima otisak i s druge ...
