Abstract The 4 N {4N} -carpets are a class of infinitely ramified self-similar fractals with large group symmetries. For -carpet F , let { F n stretchy="false">} ≥ 0...
We present a new procedural method for photorealistic rendering of woven fabric material. The goal of our research is to provide a new procedural method that renders photorealistic woven fabric without any measured data. The proposed method models the reflectance properties of woven fabric with alternating anisotropy and yarn-level surface normal manipulation. The experimental results show the ...
Abstract Kilim handicrafts are common women's craftworks in some nomadic and rural areas of Iran. These handicrafts have various textures and patterns in different parts of the country, which in some parts are representative of the culture of that region. One of the common arts in Lorestan province is kilim weaving, using traditional patterns that have undergone various changes over time. Some...
A special class of braids, called woven, is introduced and it is shown qcxthat every conjugation class of the braid group contains woven braids. In consequence tame links can be presented as plats and closures of woven braids. Restricting on knots we get the ‘woven version’ of the well-known theorem of Markov, giving moves that are capable of producing all woven braids with equivalent closures....
Abstarct: Qajar rugs are among the richest treasures of Iranian art. In these carpets , specific kind of design and new usage were created. Motifs of these group of qajar carpets not only were affected by various literary and storied themes but also reflected by religious and mystical themes. In this way, we can mention carpets of spiritual characters and darvishes. Weaving of darvish ‘s fac...
Membrane carpets consisting of alternating membrane stripes were prepared from plasma membranes of anterior and posterior chick optic tectum. Axons from retinal explants extend neurites on these carpets. Axons of the nasal retina do not distinguish between the stripes. Axons of the temporal retina prefer to extend neurites on anterior tectal membranes. Treatment of the membrane fragments with h...
Hand made rug is one of the major non-petroleum exported items which directly and indirectly supports the employment of large number of people around 8 to 9 millions in the recent years.The exportation of hand-made carpet has descended and it is considered a serious threat and may end to unemployment for a large number of the countrymen. This is one of the important reasons for the extra decrea...
Constructions of woven graph codes based on constituent convolutional codes are studied, and examples of woven convolutional graph codes are presented. Existence of codes satisfying the Costello lower bound on the free distance within a random ensemble of woven graph codes based on s-partite, s-uniform hypergraphs is shown, where s depends only on the code rate. Simulation results for Viterbi d...

Flexural strength and modulus of woven glass fiber-reinforced specimens werc significanLly greater than those without woven glass fiber (p<O.OD, Likewise, comprossive strength of reinforced specimens was signifieantly greater than those without woven glass fiber (p<O.Ol), except for specimens rcjnforced with woven glass fiber oriented at a tilt directio...
