Combination of Colour Favoured and Colour

Authors: not saved
Abstract:

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculation of D meson decays. We obtained the total decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian according to colour Favoured (C-F) and colour Suppressed (C-S). We combined them and to added amplitude of processes colour Favoured and colour Suppressed (F+S) and obtained the decay rates of them.

Colour manipulation and Colour Combination in Double-Cone Colour Space

We derive a formula for the result of the additive mixture of two colours, in double-cone space. We use NakaRushton law to combine the luminance, circular weighted averaging to combine the hue and two rules of thumb to get the resulting chromatic saturation.

Colour Emotion Models, CIELAB Colour Coordinates, and Iranian Emotional Responses

Ten colour emotional scales, namely, "Warm Cool", "Active-Passive", "Like-Dislike", "Clean-Dirty", "Fresh-Stale", "Modern-Classical", "Heavy-Light", "Hard- Soft", "Tense-Relaxed", and "Masculine-Feminine"are investigated for single-colour stimuli in CIELAB colour space within a psychophysical experiment by forty observers. The relationships between Iranian colour emotional responses and CIELAB ...
