This study examines the prediction of print defect perception (banding) of the human visual system (HVS) by combining detection probabilities of contrast components from wavelet and sinusoidal decompositions of defect patterns. Detection probabilities for basis function components are obtained from subjective tests. Prediction performance is presented in terms of the deviation of the contrast t...

We consider Bayesian estimation of a p×p precision matrix, where p can be much larger than the available sample size n. It is well known that consistent estimation in such an ultra-high dimensional situation requires regularization such as banding, tapering or thresholding. We consider a banding structure in the model and induce a prior distribution on a banded precision matrix through a Gaussi...

statement of problem: accumulation of plaque and staining due to a rough surface,  and  penetration  of  colourant  agents  from  food  and  beverages  in to the resin composite results in an incomplete polymerization. there is a little information on the effect of finishing and polishing techniques on the discoloration of nanohybrid and microhybrid composites when exposed to staining solutions...

in a 2  3  2 factorial arrangement, 144, fifty–four-week-old laying hens, in 12 treatments with 12 replicates for each treatment, received one of 12 diets based on maize or wheat containing three levels of dried tomato pomace (dtp: 0, 50 and 100 g/kg) as a substitute for wheat bran, and two levels of pigment (0 and 900 mg/kg), for 9 weeks. weight gain (wg), egg production (ep), egg weight (ew...
