  • Publication number: 20190111382
    Abstract: Provided is an acid gas separation membrane that includes an acid gas separation layer containing a hydrophilic resin and an acid gas carrier, a hydrophobic porous membrane layer supporting the acid gas separation layer, a porous membrane protective layer protecting the acid gas separation layer, and a first layer having a Gurley number of less than or equal to 0.5 times a Gurley number of the hydrophobic porous membrane layer and the porous membrane protective layer, the Gurley number of the first layer being greater than or equal to 0.1 s and less than or equal to 30 s. Also provided is an acid gas separation method using the acid gas separation membrane, as well as an acid gas separation module and an acid gas separation apparatus that each include the acid gas separation membrane.

  • Patent number: 7617102
    Abstract: A speaker identifying apparatus includes: a module for performing a principal component analysis on predetermined vocal tract geometrical parameters of a plurality of speakers and calculating an average and principal component vectors representing speaker-dependent variation; a module for performing acoustic analysis on the speech data being uttered for each of the speakers to calculate cepstrum coefficients; a module for calculating principal component coefficients for approximating the vocal tract geometrical parameter of each of the plurality of speakers by a linear sum of principal component coefficients; a module for determining, by multiple regression analysis, a coefficient sequence for estimating principal component coefficients by a linear sum of the plurality of prescribed features, for each of the plurality of speakers; a module for calculating a plurality of features from speech data of the speaker to be identified, and estimating principal component coefficients for calculating the vocal tract ge
