in order to study genetic diversity in 178 accessions of lentil (lens culinaris medik) originated from warm climate regions of iran, this experiment was conducted in 2009 at research farm of the national plant gene bank of iran in karaj. experimental design was an augmented experiment with six blocks and each block containes 30 accessions. accessions were compared with promising lines including...

Fur color that differs from the typical shades of brown and gray occurs in eight species of marmots. Albinism generally is rare whereas melanism is more common. Melanism may persist in some populations at low frequencies averaging 16.1% in M. monax and in M. flaviventris for as long as 80 years. White (not albino) and “bluish” marmots generally are rare, but a population of white M. marmota per...

This paper was presented at IS&T/SID CIC13 Conference in Scotssdale, AZ, November 7-11, 2006. Abstract Over the past twenty-five years a diversity of color display technologies has evolved to support a wide range of applications, including television receivers, computer monitors, cell phones, PDAs, automobile dashboards, aircraft instruments, and even incar and in-flight entertainment systems. ...

Web-WISE is a system designed to address the need for efficient content-based seeking and retrieval of images on the web. It supports searching by multi-features, including color and texture. Web-WISE contains three automatic components, which are 1): Internet Agent responsible for searching the Web to fetch images; 2): Analysis Agent, which extracts the color and texture features of color JPEG...

Chamomile is a medicinal plant with high economic value. In this research, 20 chamomile ecotypes collected from different regions of Iran were evaluated for genetic and chemical diversity. DNA was extracted by CTAB and polymerase chain reaction was performed using 13 RAPD markers. Essential oils extraction was performed by water distillation using Clevenger system. Components of the essential o...

Detecting faces in cluttered backgrounds and real world has remained as an unsolved problem yet. In this paper, by using composition of some kind of independent features and one of the most common appearance based approaches, and multilayered perceptron (MLP) neural networks, not only some questions have been answered, but also the designed system achieved better performance rather than the pre...

In this article, we examine the pervasive endorsement of racial color blindness—the belief that racial group membership should not be taken into account, or even noticed—as a strategy for managing diversity and intergroup relations. Despite research demonstrating the automatic perception of race (and thus the seeming improbability of actual color blindness), the color-blind approach to race has...
