Effect of olivine as MgO-bearing flux on low- and high-alumina iron ore pellets [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2023
In the present study, the effect of MgO in the form of olivine flux on low- and high-alumina iron ore pellet mineralogy and pellet quality was studied. Green pellets were prepared by varying the MgO content from 0 to 1.5% with a basicity (CaO/SiO2) of 0 ...

Decision time, slow inhibition, and theta rhythm [PDF]

open access: yes, 2010
In this paper, we examine decision making in a spiking neuronal network and show that longer time constants for the inhibitory neurons can decrease the reaction times and produce theta rhythm.We analyze the mechanism and find that the spontaneous firing

Cost-effectiveness criterion for optimal firing at surface targets by MLRS unguided rockets with ballistic aerodynamic brakes

open access: yesVojnotehnički Glasnik, 2011
A problem of selecting an artillery target while firing from a multiple launch rocket system (MLRS) is not considered frequently in literature. A solution to that problem involves a good agreement among many elements such as shooting dispersion law of ...
