Pneumatic classificationFine-metal-powderPowder metallurgyGravitational settlingWith the development of powder metallurgy industry, the fine-metal-powder classification becomes one of the vital techniques in powder technology. A pneumatic classifier without screen and mechanical moving parts is designed and ...
We found leakage on 75% of the sites we looked at and at least one instance in each of the categories. Based on the leaks we found, we propose a classification of the types of leakage that can occur via the HTTP header and use this system to analyze our results." 展开 ...

Numerous theoretical and empirical studies have claimed that project-based learning (PBL) exerts a positive impact on student development. This study explores the development and changes of students across project-based learning units by qualitative rese
The main classification criterion was segregation into primary food groups. The chemical composition of each product, as listed on the packaging, was included in a table and then assessed against the presence of any food additives. Sixteen most common additives were selected in all the investigated...

The complex stratified patina formed on Sn-bronze in chloride-rich atmospheres has been explored through long-term field exposures and short-term laboratory investigations using a multi-analytical approach. The stratified patina is composed of Cu2O- and Cu2(OH)3Cl-rich sublayers intercalated by Sn...

Deep learning is revolutionising the way that many industries operate, providing a powerful method to interpret large quantities of data automatically and relatively quickly. Deterioration is often multi-factorial and difficult to model deterministically
The grouping needs to consider several product characteristics and operational restrictions. Well-designed bundles are more attractive in the eyes of bidders (potential customers); thus, the problem has considerable effects on the selling prices. In large, multinational steel companies, the auction ...
