We introduce the independent factor analysis (IFA) method for recovering independent hidden sources from their observed mixtures. IFA generalizes and uniies ordinary factor analysis (FA), principal component analysis (PCA), and independent component analysis (ICA), and can handle not only square noiseless mixing, but also the general case where the number of mixtures diiers from the number of s...

The dielectrophoretic (DEP) separation of metallic and semiconducting single-walled carbon nanotubes (SWNTs) has been investigated. DEP separation experiments were performed by following the previous reports and the modification of Raman spectra was confirmed. We then theoretically investigated the impact of the flow field on the dielectrophoretic separation. The electrothermal flow was found t...

The separation of gases utlhzmg polymenc membranes has emerged mto a commercially utlhzed unit operation It has been recogmzed m the past decade that the separation factor for gas pairs vanes inversely with the permeablhty of the more permeable gas of the speclflc pair An analysis of the literature data for bmary gas mixtures from the hst of He, Hz, 02, Nz, CH4, and COz reveals an upper bound r...

today in developing and some developed countries source separation of waste project is following coherently because of shortage of keeping abnormal wastes places and landfill band and also economic considerations. hence, recycling and conversion materials organizations of municipalities have done some projects which resulted in increasing the participation of families in separation of valuable ...

154 specimens of periophthalmus waltoni distributed in seven different sites in the persian gulf and gulf of oman are analysed, utilizing ten morphometric characters. canonical variate analysis (cva) of the sampling sites suggested a partial separation between the north-western sites and the central plus south-eastern sites. the main factor to connect p. waltoni specimens from different sites a...
