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 ...
Uticaj frekvencije vibratora traktorskog tresača voća na oscilovanje i otkidanje plodova / The influence of a tractor fruit shaker's vibrator frequency on the oscillation and separation of fruit summary
(Naučno društvo za pogonske mašine, traktore i održavanje, Novi Sad i Univerzitet u Novom Sadu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Novi Sad, 2009)
Mehanizovano ubiranje plodova koštičavog voća omogućava racionalniji i ekonomski opravdaniji način branja, u odnosu na ručni, koji u okviru proizvodnje voća predstavlja jedan od složenijih zadataka. Udeo radne snage pri ...
Development of a collision energy absorber of a passenger train
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Development of shock absorbers is one of the necessary measures for passive protection of passenger coaches. The purpose of passive protection is to minimize the collision consequences for passengers. Present solutions are ...

Prediction of automotive friction material characteristics using artificial neural networks-cold performance
(Elsevier Science Sa, Lausanne, 2006)
In this study, an artificial neural network technique was used to predict the cold performance of the automotive friction material. Cold performance was predicted for two cases: (i) before and (ii) after fading and recovery ...
Kinetic phenomena in charged particle transport in gases, swarm parameters and cross section data
(IOP Publishing Ltd, Bristol, 2007)
In this review we discuss the current status of the physics of charged particle swarms, mainly electrons. The whole field is analysed mainly through its relationship to plasma modelling and illustrated by some recent ...
