In geology, cla.sifica.ion a.d lithologica. recognition of rocks pla.s a. importa.t role in the a.ea.of oil a.d ga. explora.ion, minera. explora.ion a.d geologica. a.a.ysis. In other fields of a.tivity such a. construction a.d decora.ion, this cla.sifica.ion ma.es sense a.d fully pla.s its role. However, this cla.sifica.ion is slow, a.proxima.e a.d subjective. a.toma.ic cla.sifica.ion curbs this subjectivity a.d fills this ga. by offering methods tha. reflect huma. perception. We propose a.new a.proa.h to rock cla.sifica.ion ba.ed on direct-view ima.es of rocks. The a.m is to ta.e a.va.ta.e of fea.ure extra.tion methods to estima.e a.rock dictiona.y. In this work, we ha.e developed a.cla.sifica.ion method obta.ned by conca.ena.ing four (4) K-SVD va.ia.ts into a.single signa.ure. This method is ba.ed on the K-SVD a.gorithm combined with four (4) fea.ure extra.tion techniques: DCT, Ga.or filters, D-a.BPCSF a.d G-a.BPCSF, resulting in the four (4) va.ia.ts na.ed K-Ga.or, K-DCT, KD-a.BPCSF a.d KD-a.BPCSF respectively.

This work presents a.new a.proa.h for simula.ing the ra.dom wa.es in viscous fluids a.d the a.socia.ed bottom shea. stresses. By genera.ing the incident ra.dom wa.es in a.numerica. wa.e flume a.d solving the unstea.y two-dimensiona. Na.ier-Stokes equa.ions a.d the fully nonlinea. free surfa.e bounda.y conditions for the fluid flows in the flume, the viscous flows a.d la.ina. bottom shea. stresses induced by ra.dom wa.es a.e determined. The deterministic spectra. a.plitude method implemented by use of the fa.t Fourier tra.sform a.gorithm wa. a.opted to genera.e the incident ra.dom wa.es. The a.cura.y of the numerica. scheme is confirmed by compa.ing the predicted wa.e spectrum with the ta.get spectrum a.d by compa.ing the na.lerica. tra.sfer function between the shea. stress a.d the surfa.e eleva.ion with the theoretica. tra.sfer function. The ma.imum bottom shea. stress ca.sed by ra.dom wa.es, computed by this wa.e model, is compa.ed with tha. obta.ned by myrha.g＇ s model （1995）. The tra.sfer function method is a.so employed to determine the ma.imum shea. stress, a.d is proved a.cura.e.

Prosta.e ca.cer (PCa. is the most common ca.se of ma.igna.cy in ma.es a.d the third lea.ing ca.se of ca.cer morta.ity in the United Sta.es.

If X is a. a.plund spa.e, then every uniformly continuous function on Bx＊ which is holomorphic on the open unit ba.l, ca. be perturbed by a.w＊ continuous a.d homogeneous polynomia. on X＊ to obta.n a.norm a.ta.ning function on the dua. unit ba.l. This is a.consequence of a.version of Bourga.n-Stega.l＇s va.ia.iona. principle. We a.so show tha. the set of N-homogeneous polynomia.s between two Ba.a.h spa.es X a.d Y whose tra.sposes a.ta.n their norms is dense in the corresponding spa.e of N-homogeneous polynomia.s. In the ca.e when Y is the spa.e of Ra.on mea.ures on a.compa.t K, this result ca. be strengthened.
