Lung cancer is one of the most fatal disease with high lethality. In general lung cancers are diagnosed by radiologists. But checking radiological image is a very toilsome work for radiologists because it requires long time practice and high concentr

Separation of NaCN from the mixture of NaCN and Na2CO3 (which is mainly produced by urea and sodium carbonate method) was studied. The soluble possibility of NaCN and Na2CO3 in different mixed solvents was theoretically investigated. The experimental

The solubility of NaCN and Na2CO3 in the water–ethanol mixture was determined through experiments. Also the polynomial fit was used to lead to the relationship between the solubility of NaCN/Na2CO3 and the solvent composition. In the meantime, the

Although extreme learning machine (ELM) provides better generalization performance at a much faster learning speed than traditional learning algorithms, the classical ELM can not obtain ideal results for the imbalanced data problem. In this paper, in
