Improvement of conversion efficiency of atom-molecule Bose-Einstein condensate
, 2007 We investigate the stimulated Raman adiabatic passage in two-color photoassociation for a atom-molecule Bose-Einstein condensate. By applying two time-varying Guassian laser pulses that fulfill generalized two-photon resonance condition, we obtain highly

Optimization of Color Conversion for Face Recognition
EURASIP Journal on Advances in Signal Processing, 2004 This paper concerns the conversion of color images to monochromatic form for the purpose of human face recognition. Many face recognition systems operate using monochromatic information alone even when color images are available.

Tripling the Optical Efficiency of Color-Converted Micro-LED Displays with Funnel-Tube Array
Crystals, 2019 Color-converted micro-LED displays consist of a mono-color micro-LED array and color conversion materials to achieve full color, while relieving the burden of epitaxial growth of three-color micro-LEDs. However, it usually suffers from low efficiency and

, 1999 We examine the effects of color screening on the transition of a parton plasma into a hadron gas at RHIC energies. It is found that as expected, color screening posed itself as a significant barrier for hadronization.

Transparent organic light-emitting diodes with different bi-directional emission colors using color-conversion capping layers [PDF]
, 2017 We report a study on transparent organic light-emitting diodes (OLEDs) with different bidirectional emission colors, enabled by color-conversion organic capping layers. Starting from a transparent blue OLED with an uncapped Ag top electrode exhibiting an

Color stability and degree of conversion of gingiva‐colored resin‐based composites
Journal of Esthetic and Restorative Dentistry, 2023 AbstractObjectivesTo evaluate gingiva‐colored resin‐based composites' (GCRBC) color stability and degree of conversion (DC%).MethodsEight discs (8 × 1 mm) of 20 shades of GCRBC were prepared. Color coordinates were measured against a gray background with a calibrated spectroradiometer, CIE D65 illuminant and the CIE 45°/0° geometry at baseline and ...

Image Color Conversion by Illumination
Journal of Information Technology & Software Engineering, 2017 We developed a software program to imitate the color of an object within the range of sRGB on a PC display. The obtained colors were converted from the picture information taken under a white light source, such as D65. Other, arbitrary light sources such as natural sunlight or standard illuminants, could be used in addition to the test illumination ...
