Spectral Separation for Multispectral Image Reproduction Based on Constrained Optimization Method
The constrained optimization method is employed to calculate the colorant values of the multispectral images. Because the spectral separation from the 31-dimensional spectral reflectance to low dimensional colorant values is very complex, an inverse ...

Rare Earths and the Balance Problem: How to Deal with Changing Markets? [PDF]
The balance between the market demand and the natural abundance of the rare-earth elements (REEs) in ores, often referred to as the Balance Problem (or the Balancing Problem), is a major issue for REE suppliers.

In another paper, L,3 the author has given a proof of a formula for M(λ), the number of ways of coloring a graph in λ colors, due to Birkhoff. The numbers m ij , in terms of which M(λ) is expressed, are here studied in detail; a method of calculating them is given.

Color realism and color science [PDF]
AbstractThe target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically, types of reflectance.

Innovación tecnológica en la tintura de la lana con colorantes dispersos azoicos vía liposomas. [PDF]
Se estudia la aplicación de liposomas unilamelares como carriers de colorantes dispersos de tipo azoico en la tintura de la lana. Se utilizaron liposomas unilamelares (L U V) constituidos por fosfatidilcolina de huevo (PC) y que contenían el colorante ...

Characterization and digital restauration of XIV-XV centuries written parchments by means of non-destructive techniques. Three case studies [PDF]
Parchment is the primary writing medium of the majority of documents with cultural importance. Unfortunately, this material suffers of several mechanisms of degradation that affect its chemical-physical structure and the readability of text.

Color categories and color appearance [PDF]
We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were ...

The Hybrid ColorAnt-RT Algorithms and an Application to Register Allocation
Ant Colony Optimization is a metaheuristic used to create heuristic algorithms to find good solutions for combinatorial optimization problems. This metaheuristic is inspired on the effective behavior present in some species of ants of exploring the ...

CAROTENOIDS AS NATURAL COLORANT : A REVIEW
Color is quality attribute that is usually used by consumer as first assessment to choose the food product. However, food processing is one of process which can degrade the food’s color, so the colorant is usually added.
