Ore-waste discrimination with adaptive sampling strategy
(Springer, 2020)
Grade control and short-term planning determine the performance of a mining project. Improving this decision, by collecting the most informative samples (data) may have significant financial impact on the project. In this ...
The VLA/ALMA nascent disk and multiplicity (VANDAM) survey of Orion protostars. A statistical characterization of class 0 and I protostellar disks
(IOP Publishing, 2020)
We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of similar to 0.'' (40au), including observations with the Very ...
Relation between mechanical and textural properties of dense materials of tetragonal and cubic zirconia
(Int Inst Science Sintering (i I S S), 2016-04)
In the current paper we present a study of the sinterability of two zirconia (ZrO2) nanopowders with different content of yttrium oxide (Y2O3) 3 and 8 % tetragonal and cubic zirconia, respectively. After sintering between ...
