Motivated from problems in canonical correlation analysis, reduced rank regression and sufficient dimension reduction, we introduce a double dimension reduction model where a single index of the multivariate response is linked to the multivariate covariate through a single index of these covariates, hence the name double single index model. Since nonlinear association between two sets of multiv...

We demonstrate a novel approach to obtain a resonance linewidth below the transit limit. The cross correlation between the induced intensity modulation of two lasers coupling the target resonance exhibits a narrow spectrum. 1/30 of the transit-limited width is achieved in a proof-of-principle experiment where two ground states are the target resonance levels. Attainable linewidth is only limite...

A stereo algorithm that can estimate multiple depths in semi-transparent images is presented. The algorithm is based on a combination of phase analysis and canonical correlation analysis. The algorithm adapts lters in each local neighbourhood of the image in a way which maximizes the correlation between the ltered images. The adapted lters are then analysed to nd the disparity. This is done by ...

the writers of this research have studied seven variables including: precipitation, relative humidity, sunny hours, temperature average, temperature minimum, temperature maximum and sea level pressure, at sanandaj air station during 1964-1994. sanandaj air station has nearly 10966 days of complete data for these variables. a principal component analysis (pca) has been applied on this data; then...

crested wheatgrass (agropyron cristatum (l.) gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. the main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of iran as low-maintenance turfgrass. the experimental design was a randomized complete block design with 3 re...

abstract salinity is one of the major abiotic challenges influencing plant productivity worldwide. to examine the response of two alfalfa cultivars (bami and hamedani) to six levels of water salinity (0, 25, 50, 75, 100, 125 mm l-1 nacl), a glasshouse experiment was conducted at the college of agriculture, shiraz university, shiraz, iran in 2008. the results showed that in bami (which appeared...
