In this paper, we proposed the fusion of two methods to know principal component analysis (PCA) in the domain DCT and singular value decomposition (SVD). Experimental results performed on the standard database ORL which prove that the proposed approach achieves more advantages in terms of identification and processing time.

Orphanin FQ/nociceptin (OFQ/N), the most recently identified endogenous opioid peptide, stimulates prolactin secretion in both male and female rats. OFQ/N, however, did not elicit this stimulatory effect through the mu-, delta-, or kappa-opiate receptor subtype. The role OFQ/N plays in prolactin regulation under physiological conditions and its mechanism of action are not known. The purpose of ...

The ability of neuropeptide Y to potently stimulate food intake is dependent in part upon the functioning of mu and kappa opioid receptors. The combined use of selective opioid antagonists directed against mu, delta or kappa receptors and antisense probes directed against specific exons of the MOR-1, DOR-1, KOR-1 and KOR-3/ORL-1 opioid receptor genes has been successful in characterizing the pr...

in the present study, five log-normal models, normal model (n), and two four- parameter models namely gompertz (g) and fredlund (fr) were tested on 71 psd data from 10 soil textural classes. the jaky (j) and fr models had the smallest and largest r2 values for all of the soils, respectively. the results of comparing the n and simple log-normal (sl) models showed that the accuracy of the n model...

automatic facial recognition has many potential applications in different areas of humancomputer interaction. however, they are not yet fully realized due to the lack of an effectivefacial feature descriptor. in this paper, we present a new appearance based feature descriptor,the local directional pattern (ldp), to represent facial geometry and analyze its performance inrecognition. an ldp feat...
