The main goal of this study is determination the effect of GCR (gray component replacement) levels on colorimetric characteristics of color proof. To determine the effect of GCR levels on colors of color proofs, a comparison of 2D and 3D color gamuts depending on GCR level have been performed. In addition to obtain better assessment of the effect of GCR levels on color gamut were calculate volu...

We have evaluated three analytical methods for determining inorganic phosphorus in serum applied to the Technicon RA-I000 analyzer: a fully enzymatic colorimetric method based on the specific system purine nucleoside phosphorylase/xanthine oxidase coupled to an indicator colorimetric reaction similar to the Trinder reaction; a chemical method involving the direct UV measurement of the phosphomo...

background; dithiocarbamates, the main group of fungicides, are used to control about 400 pathogens in more than 70 crops. these pesticides are widely applied to crops including potato, cereal, apple, pear and leafy vegetables throughout the world since 1960. from the late 1980s, using these fungicides has caused much debate among regulators about their long-term effects on consumers and occupa...

A new nonlinear dimensionality reduction method for multi-spectral images was presented to solve the problem brought by high dimensionality of multi-spectral images during color reproduction. Firstly, according to the characteristics of human visual system, the CIE standard observer color matching functions were weighted to the source spectral reflectance and then a principal component analysis...

The present paper studies two different table-based approaches for the calibration of electronic imaging systems. The first approach, which is the classical one,uses the device-independent CIE-XYZ colorimetric space as an intermediate standard space. Input and output devices such as scanners, displays and printers are calibrated separately with respect to the objective CIE-XYZ space. The calibr...

Abstract This work investigates the results of laser irradiation synthesis nanoparticles on gold surface. The sizes and chemical composition produced were determined, possibility changing colorimetric characteristics surface was shown.

Colorimetry is an important on-site detection method for organophosphorus compounds. O-Ethyl S-(2-diisopropylaminoethyl) methylphosphonothioate (VX) recognized as one of the deadliest chemical agents, and rapid VX great significance to public safety. In this paper, a squaraine derivative was synthesized probe molecules, sensing characteristics in colorimetric solution system containing tetrabut...
