Using Multi-Scale Attention for Semantic Segmentation | …
A white color for attention indies a high value (close to 1.0). The attention values for a given pixel across all scales sums to 1.0. Left: The thin road-side posts are best resolved at 2x scale, and the attention successfully attends more to that scale than other scales, as evidenced by the white color for the posts in the 2x attention image.
US Patent for Non-fused aluminum oxide-based abrasive …
Fused alumina usually outperforms fused alumina: zirconia in this test. EXAMPLE 47 Abrasive grinding wheels were prepared by conventional cold molding techniques to produce grinding, cut-off and cup abrasive wheels, using both fused alumina abrasive grain as a control and non-fused abrasive grain according to Example 11 of the present invention.

Aluminium production process
ALUMINA PRODUCTION Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in
Alumina Refining | The Aluminum Association
Alumina is the common name given to aluminum oxide (Al 2 O 3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite.
How to Polish Fused Silica to Obta in the Surface Damage …
process. ARO chose to do the Pre-Polish step using Ultra Sol-M5-PS (an alumina polishing compound), and a 0.8- alumina slurry. The pH of the slurry was maintained at ~ 8 to prevent Orange Peel ; which is the effect the acidic slurry can have on fused

Synthesis of Heteroatom Substituted SBA-15 by the “pH …
A simple and effective method denoted “pH-adjusting” is used to graft a large amount of heteroatoms such as Al and Ti to mesoporous silica material SBA-15. The products prepared by this method show highly ordered mesostructures with large surface areas and uniform mesopore size distribution. The results of ICP, EDX, 27Al NMR, calcium ion-exchange capacity, and UV−vis spectra show that
Fused Silica | SiO2 Material Properties
