From real spectroradiometric data, we propose an algorithm to obtain camera opto-electronic conversion functions (camera OECFs) for different values of the lens aperture N from the opto-electronic conversion spectral functions (OECSFs). Working in the linear range of the inverse OECFs, we have found that the slope vs. lens aperture function is fitted by a second order polynomial. This happens a...

The system for colorimetry adopted by the Commission Internationale de l'Eclairage (CIE) in 1931, along with its subsequent improvements, represents a family of light mixture models that has served well for many decades for stimulus specification and reproduction when highly controlled color standards are important. Still, with regard to color appearance many perceptual and cognitive factors ar...

Meat and carcass quality attributes are of crucial importance influencing consumer preference and profitability in the pork industry. A set of 400 Berkshire pigs were collected from Dasan breeding farm, Namwon, Chonbuk province, Korea that were born between 2012 and 2013. To perform genome wide association studies (GWAS), eleven meat and carcass quality traits were considered, including carcass...

OBJECTIVE To evaluate the sealing ability of two different types of Glass Ionomer Cements (GICs) used for sandwich restorations and assess the effect of acid etching of GIC on microleakage at GIC-resin composite interface. STUDY DESIGN Experimental study. PLACE AND DURATION OF STUDY Department of Operative, DIEKIOHS (DUHS) and NED University, Karachi, from February to June 2011. METHODOLO...

The current global economy has increased international competition and the need to improve the quality of many manufactured products. Appearance measurements are used to determine the quality and acceptability of a variety of products from textiles to machine finishes. Since the manufacture and marketing of these products is international in scope, the methods, instruments, and standards for th...

BACKGROUND/AIMS The aim of our study was to compare the characteristics of nosocomial infective endocarditis (NIE) with community-acquired infective endocarditis (CIE) and to determine independent risk factors for in-hospital death. METHODS We retrospectively reviewed the medical records of 560 patients diagnosed with infective endocarditis. NIE was defined by a diagnosis made > 72 hours afte...

Configurational information entropy (CIE) theory was employed to determine the neutron-skin thickness of neutron-rich calcium isotopes. The nuclear density distributions and fragment cross sections in 350 MeV/u $$^{40-60}$$ Ca + $$^{9}$$ Be projectile fragmentation reactions were calculated using a modified statistical abrasion-ablation model. CIE quantities determined from density, isotopic, m...

The aim of this study was to evaluate color inconstancy dental ceramics under the white light-emitting diode illuminants recently proposed by CIE. From spectral reflectance factors 18 (VST, NSP, and IEC; shades A1, A2, A3, A3.5, B2, C2), corresponding colors illuminant D65 CIE 1931 Standard Colorimetric Observer were computed for all samples, using chromatic adaptation transform CIECAT16. CIEDE...
