Determination of Archard's wear coefficient and wear simulation of sliding bearings
(Emerald Group Publishing Ltd, Bingley, 2019)
Purpose This paper aims to present the methodology to determine Archard's wear coefficient. By applying this coefficient into the numerical simulation of wear, it is possible to predict wear without long lasting and usually ...
Probabilistička analiza uređaja za razdvajanje odnosa naponskog razdelnika / Probabilistic analysis of voltage divider ratios
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Tolerancija modernih otpornika obično varira od 0.1% do 1 %. Sa probabilističke tačke gledišta to znači da se odgovarajući otpor može posmatrati kao slučajna promenljiva sa odgovarajućom funkcijom gustine raspodele verovatnoće ...
