CIE Work in Color Imaging
The CIE Board of Administration has proposed a new Division to study procedures and prepare guides and standards for the optical, visual and metrological aspects of the communication, processing, and reproduction of images, using all types of analogue and digital imaging devices, storage media and imaging media. While current practice enables adequate color communication within single industrie...
متن کاملCIE Colorimetry and Colour Displays
CIE colorimetry was standardised 65 years ago to describe colorimetric properties of signal lights. The first real application of CIE colorimetry occurred, however, in the textile and coating industries to describe colour matches between sample and reference. Thus also the experiments conducted to achieve a uniform colour scale diagram were performed by using material samples usually illuminate...

متن کاملIs Phlebotomus argentipes Annandale and Brunetti (Diptera: Psychodidae) autogenous?
Phlebotomus argentipes is an established vector of visceral leishmaniasis in India and other countries of the sub-continent1,2.

However, the blood meal analysis proves that it is anthropophilic as well as zoophilic in nature4. Female P. argentipes takes blood from ...
متن کاملCharacterisations of Nelson Algebras
Nelson algebras arise naturally in algebraic logic as the algebraic models of Nelson’s constructive logic with strong negation. This note gives two characterisations of the variety of Nelson algebras up to term equivalence, together with a characterisation of the finite Nelson algebras up to polynomial equivalence. The results answer a question of Blok and Pigozzi and clarify some earlier work ...
