A probabilistic neural network (PNN) is a feed-forward neural network using a smoothing parameter. We used the PNN algorithm based on single and multi-smoothing parameters for multi-dimensional data classification. Using multi-smoothing parameters, w

PNN is a feed-forward neural network in which there is an important parameter called smoothing parameter. This work implemented a combination of PNN with PSO optimization in order to estimate unique smoothing parameters for each SWIR bands of ASTER i

Consumption of zinc metal has been rapidly increased in the world. Zinc metal exists as oxide, sulfide, carbonate and silicate ores, among which zinc oxide ores have not been mined because it is very difficult to separate zinc from gangue or to conce

This study aimed to introduce a new approach to determine the mass transfer rate constant in a laboratory column flotation through an analogy to a mass transfer process. The RTD of the column at two separate bubble sizes were modeled using both conve

A common problem in column flotation research is designing the appropriate cell which provides all the requirements of the desired tests. The drift flux model and the axial dispersion model were used in this paper for designing a column flotation cel
