Predviđanje veka čeličnog žičanog užeta u eksploataciji / Service life prediction of running steel wire ropes
(Institut za ispitivanje materijala, Beograd, 2010)
Vrlo visoka čvrstoća omogućava žičanom užetu da prenese velike zatezne sile i da se kreće po koturima relativno malog prečnika. Žice od čelika vrlo visoke čvrstoće su postojale više od sto godina pre nego što su patentirane, ...
The contraction principle for set valued mappings on a metric space with a graph
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Let (X, d) be a metric space and F : X hooked right arrow X be a set valued mapping. We obtain sufficient conditions for the existence of a fixed point of the mapping F in the metric space X endowed with a graph G such ...
Primena veštačke neuronske mreže i fraktala u predikciji ponašanja površina biomedicinskih materijala / Application of artificial neural network and fractals in biomedical materials surface behavior prediction
(Savez inženjera i tehničara Srbije, Beograd, 2010)
Primer biomedicinske površine, koji je predmet istraživanja opisan u ovom radu, je unutrašnja površina gas-propusnog sočiva obrađena struganjem na mikro-strugu sa alatom sa dijamantskim vrhom i polirana pastom koja sadrži ...
Ambiguous Influence of Radiation Effects in Solar Cells
(Electromagnetics Academy, 2010)
Regardless of the very high standards in the production of electronic devices, all of them are more or less, prone to the effects of aging even if they are not exposed to extreme (hostile) working conditions. One of the ...

Possibility of the abrasive wear resistance determination with scratch tester
(Springer/Plenum Publishers, New York, 2010)
Abrasion wear resistance is very important in many applications and it is not a surprise that there are many laboratory test methods for its determination. In this article, a possibility of the abrasive wear resistance ...
Mock-up testing facilities and qualification strategy for EU ITER TBMs
(Elsevier Science Sa, Lausanne, 2010)
European test blanket modules (TBM) for both European blanket concepts, namely the Helium Cooled Lithium Lead (HCLL) and the Helium Cooled Pebble Bed (HCPB), and their auxiliary systems have been designed in the last years. ...
Theoretical-experimental determining of cooling time (t8/5) in hard facing of steels for forging dies
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
This paper investigates the accuracy of analytical, empirical, and numerical expressions, i. e. the most favourable methods for calculating the cooling time from 800 to 500°C (t8/5). The degree of accuracy of time t8/5 is ...
Neural network prediction of brake friction materials wear
(Elsevier Science Sa, Lausanne, 2010)
Wear of brake friction materials depends on many factors such as temperature, applied load, sliding velocity, properties of mating materials, and durability of the transfer layer. Prediction of friction materials wear ...
