No difference in variability of unique hue selections and binary hue selections [PDF]

open access: yes, 2014
If unique hues have special status in phenomenological experience as perceptually pure, it seems reasonable to assume that they are represented more precisely by the visual system than are other colors. Following the method of Malkoc et al. (J. Opt. Soc.

Translating conventional wisdom on chicken comb color into automated monitoring of disease-infected chicken using chromaticity-based machine learning models

open access: yesFrontiers in Veterinary Science, 2023
Bacteria- or virus-infected chicken is conventionally detected by manual observation and confirmed by a laboratory test, which may lead to late detection, significant economic loss, and threaten human health.

SYNTHESIS AND PHOTOLUMINESCENCE STUDIES OF YTTRIUM ZIRCONATE (YZO) PHOSPHORS POWDERS DOPED WITH BI3+ IONS [PDF]

open access: yesProceedings on Engineering Sciences
In this research work, Yttrium Zirconate (Y2Zr2O7 = YZO) phosphors doped with varying percentages of Bi3+ ions (x = 1.0, 1.5, 2.0, and 2.5) were successfully synthesized using a simple co-precipitation method and subsequently annealed at 1300°C.
