this article is an attempt to investigate the aesthetics of color themes in arabic poetry. as a means of psychological description, color is one of the manifestations of realism in poetic images. in the application of colors some mythical and civilized structures are portrayed in the culture of nations. since languages have their own specific organizations of colors, the author aims to measure ...

the manifest of value of colors in nazik al-malaika s poemsali piranishal *khadije hashemi**from the early times, colors have played an important role in developing poeticimages, and colorful images are the realistic and sensory aspects among poets. poetshave used colorful words to explore and explain the relationship between poeticimages and sometimes they have used colorful words to express t...

In Ramsey theory (a branch of combinatorics) one often proves that a function exists by giving enormous bounds on it. The function’s actual values may be much smaller; however, this is not known. In this paper we explore variants and special cases of these functions where we obtain much smaller bounds. The following is known: no matter how the lattice points of a coordinate plane are colored re...

A mixed hypergraph H is a triple (X,C,D), where X finite set and each of C D family subsets X. For any positive integer ?, proper ?-coloring an assignment ? colors to vertices in such that member contains at least two assigned the same color different colors. The chromatic polynomial graph-function counting number distinct ?-colorings whenever integer. In this article, we show polynomials hyper...

For a simple graph G, let c( G) denote the choice number of G, and for k ~ x( G) let Ck( G) be defined as c( G) is defined, except that there are only k colors available to form the lists of colors available to the vertices. The thwart number of G, denoted thw( G), is the smallest k such that Ck( G) c( G). To put it another way, thw( G) is the smallest number x( G)) of colors you need in order ...

In this paper we describe a non-parametric probabilistic model that can be used to encode relationships in color naming datasets. This model can be used with datasets with any number of color terms and expressions, as well as terms from multiple languages. Because the model is based on probability theory, we can use classic statistics to compute features of interest to color scientists. In part...

To attract children's interest in Chemistry, the youngSCS composed this easy science experiment about chromatography. It shows a beautiful and simple way behind colors explains common laboratory technique. best reach its target audience was published “Kaleio”, Swiss girl’s magazine.

A sequence of symbols a1, a2 . . . is called square-free if it does not contain a subsequence of consecutive terms of the form x1, . . . , xm, x1, . . . , xm. A century ago Thue showed that there exist arbitrarily long square-free sequences using only three symbols. Sequences can be thought of as colors on the vertices of a path. Following the paper of Alon, Grytczuk, Ha luszczak and Riordan, w...
