Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
Jedan pristup optimizaciji tankozidih konzolnih nosača otvorenih poprečnih preseka / An approach to the optimization of thin-walled cantilever open section beams
(Srpsko društvo za mehaniku, Beograd, 2007)
U ovom radu je razmatran jedan pristup optimizaciji tankozidih konzolnih konstrukcionih elemenata otvorenih poprečnih preseka izloženih savijanju i ograničenoj torziji. Problem je redukovan na određivanje minimalne mase ...
Analytical model of a Si TFT with cylindrical source and drain
(IEEE, New York, 2008)
In this paper a new analytical model of a silicon Thin Film Transistor (Si TFT) with cylindrical source and drain, is presented. In first part of the text. some basic TFT characteristics and possible applications are ...
Conversion of a left-hand circularly polarized whistler wave into the magnetic energy of a controllable helical wiggler wave
(Plasma Devices and Operations, 2009)
A linearly polarized electromagnetic source wave splits into six traveling wave modes (three of them are right-hand circularly-polarized (RCP) modes and three are left-hand circularly-polarized (LCP) modes) due to the ...
Pretovarni mostovi sa elevatorima, deo II - konstrukciono rešenje, tehnologija i proračun rekonstruisane strukture / Unloading bridges with reclaimers, Part II: Structural solution, technology and calculus of structural reengineering
(Savez inženjera i tehničara Srbije, Beograd, 2007)
Četiri pretovarna mosta raspona 50 m, kapaciteta 300 t/h opslužuju otvoreno skladište uglja u TE "Kolubara" - Veliki Crljeni. Tokom njihove eksploatacije dolazilo je do relativno čestih zastoja izazvanih nedostatcima noseće ...
An inequality for the Lebesgue measure and its further applications
(Univerzitet u Kragujevcu - Prirodno-matematički fakultet, Kragujevac, 2008)
In [Univ. Beograd Publ. Elektrotehn. Fak. Ser. Math. 15 (2004), 85-86], the first author of this paper proved a new inequality for the Lebesgue measure and gave some applications. Here, we present a new application of this ...
Data and modeling of negative ion transport in gases of interest for production of integrated circuits and nanotechnologies
(Elsevier, Amsterdam, 2007)
We review techniques to prepare, evaluate and apply sets of cross section and transport data for negative ions that are required for the modeling of collisional non-equilibrium plasmas used for processing of microelectronic ...

Effect of thixocasting and heat treatment on the tribological properties of hypoeutectic Al-Si alloy
(Elsevier Science Sa, Lausanne, 2008)
This paper presents results of structural, mechanical and tribological tests of thixocast hypoeutectic Al-Si alloy A356 (EN AlSi7Mg0.3). The pin-on-disc tribometer was used to carry out tribological tests under dry sliding ...
The influence of variable operating conditions on the design and exploitation of fly ash pneumatic transport systems in thermal power plants
(Brazilian Soc Chemical Eng, Sao Paulo, 2008)
The efficiency of an air-slide pneumatic conveying system depends, first of all, on several basic elements chosen or calculated during the design of a plant: air-slide design parameters, air mover characteristics, as well ...
