Dinamička stabilnost viskoelastičnih kontinualnih sistema pod dejstvom slučajnih poremećaja / Dynamic stability of viscoelastic continuous systems subjected to random excitation
(Универзитет у Нишу, Машински факултет, 25-12-2014)
Dynamic stability of elastic and viscoelastic mechanical systems and nanostructures
under the influence of axial forces which are represented by time dependent stochastic
functions is analyzed in this dissertation. These ...
Istraživanje konstrukciono-triboloških parametara kugličnih ležaja sa kosim dodirom tipa ZKLF sa aspekta optimalne osnovne funkcije
(Универзитет у Нишу, Машински факултет, 27-09-2018)
From modern machine systems is expected to increase productivity (as many
processing units per unit of time). Accordingly, the processing speeds must
be significantly increased. With the increase in processing speed, it ...
