The primary goal of a color characterization model is to establish a mapping from digital input values d i (i ϭ R,G,B) to tristimulus values such as XYZ. A good characterization model should be fast, use a small amount of data, and allow for backward mapping from tristimulus to d i. The characterization models considered here are for the case of an end user(More)
OBJECTIVE To test the hypothesis that extending the number of consecutive active oral contraceptives (OC)s given will decrease the frequency of menstrual-related problems including dysmenorrhea, menorrhagia, premenstrual-type symptoms, and menstrual migraines. METHODS A prospective analysis was designed to track the experiences of 50 women taking OCs and(More)
The number of colorants used in printers is growing to improve quality of the prints in terms of gamut size, grain and metamerism. In this paper we demonstrate a modification to the existing models (Cellular Neugebauer Model, with Yule Nielson Correction) to simulate spectral reflectance of an N-ink printer. This is achieved by imposing a constraint for the(More)
The primary goal of a colour characterization model is to establish a mapping from digital input values d i (i=R,G,B) to tristimulus values such as XYZ. A good characterization model should be fast, use a small amount of data, and allow for backward mapping from tristimulus to d i. This paper demonstrates implementations of three different colour(More)
Both the number of motile spermatozoa inseminated and the site of insemination have been correlated with the probability of pregnancy in patients inseminated with donor sperm cells from fertile men. Nevertheless, more data on the minimum sperm dose required to achieve a pregnancy are needed to understand this apparent relationship. We analyzed(More)
