Comparison in the RGB domain is not suitable for precise color matching, due to the strong dependency of this domain on factors like spectral power distribution of the light source and object geometry. We have studied the use of multispectral or hyperspectral images for color matching, since it can be proven that hyperspectral images can be made independent of the light source (color constancy)...

Beginning phonetics students are taught that American English has two contrasting reduced vowels, transcribed as [ ́] and [È], illustrated by the unstressed vowels in the minimal pair Rosa’s vs. roses. However little seems to be known about the precise nature or distribution of these vowels. This study explores these questions through acoustic analysis of reduced vowels in the speech of twelve A...

The problem of logical omniscience arises at two levels. One is the individual level, where an agent is assumed to have reasoning powers which are unrealistic. The other, equally important one, is where two or more agents are supposed to share a state of knowledge (perhaps common knowledge) which is read off from a physical situation, but which may not hold in practice. By reducing knowledge to...

scented rose species are very important in the genus rosa due to their use in highly-prized essential oil production and as garden roses. the fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. a comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly damask r...

In this article we present RoSeS (Really Open Simple and Efficient Syndication), a generic framework for content-based RSS feed querying and aggregation. RoSeS is based on a data-centric approach, using a combination of standard database concepts like declarative query languages, views and multiquery optimization. Users create personalized feeds by defining and composing content-based filtering...
