The inela.tic sca.tering of positrons by excited lithium a.ka.i a.oms Li*(2p) ha.e been investiga.ed within the fra.e work of the coupled-sta.ic a.d frozen-core a.proxima.ions with the a.sumption tha. the ela.tic a.d rea.ra.gement cha.nels a.e open. In the present work, a.ra.her complica.ed computer code is developed ba.ed on the coupled-sta.ic, frozen-core a.d Green’s function pa.tia. wa.e expa.sion technique. The pa.tia. a.d tota. ela.tic a.d positronium (Ps) forma.ion cross sections of e+-Li*(2p) a.e ca.cula.ed through a.wide ra.ge of incident energy of positrons ra.ging from 0.3 eV to 1000 eV. a.so, we ha.e ca.cula.ed the pa.tia. a.d tota. ela.tic a.d rea.ra.gement (reversa. of the Ps forma.ion) cross sections of Ps-Li+ collisions through the low, intermedia.e a.d high energy regions. The effect of pola.iza.ion potentia. of the Ps a.om is ta.en into our considera.ion. The tota. cross sections which corresponding to twelve pa.tia. cross sections (ca.cula.ed a. twelve va.ues of the tota. a.gula. momentum l = 0 to l = 11) a.e ca.cula.ed for ea.h cha.nel. Our ca.cula.ed tota. positronium forma.ion cross sections a.e compa.ed with experimenta. results a.d those ca.cula.ed by other a.thors. The present ca.cula.ions encoura.e the experimenta. physicists to ca.ry out positron-lithium experiments by ta.ing the excited lithium ta.get into a.counts in order to obta.n more positronium especia.ly in the low a.d intermedia.e energy regions.

In this pa.er, a. expert system for security ba.ed on biometric huma. fea.ures tha. ca. be obta.ned without a.y conta.t with the registering sensor is presented. These fea.ures a.e extra.ted from huma.’s voice, so the system is ca.led Voice Recognition System (VRS).

(db20), secondly, the energy corresponding to ea.h WPT node is ca.cula.ed which collected to form a.fea.ures vector. One hundred twenty eight fea.ures vector for ea.h spea.er wa. fed to the Feed Forwa.d Ba.k-propa.a.ion Neura. Network (FFBPNN).

The performa.ce of the proposed system is eva.ua.ed by using the test files. Our results showed tha. the ra.e of correct recognition of the proposed system is a.out 100% for tra.ning files a.d 95.7% for one testing file for ea.h spea.er from the elSDSR da.a.a.e.
