مطالعه فن شناسی نقشه قالی دو منطقه اصفهان و کرمان (بررسی یک نمونه از هر منطقه)
Conservation and preservation of carpet design cartoons requires a scientific con servation plan appropriate for each case study. The research into the carpet designs of Kerman and Isfahan regions was carried out in 2003 in order to gain access to a comprehensive and exact method for their conservation. In this research, besides the differences in the techniques of producing carpet designs...
متن کاملجدا کردن رنگ کاراملی از ملاس چغدرقند و بررسی ویژیگی ها و کاربرد آن در صنایع غذایی
Molasses are produced in large amounts by sugar cane and sugar beet factories every year. However, they are considered as the waste product of the crystallization plants. Thus, although they contain significant amounts of materials with deep black colour which can be separated as food colour, molasses are very cheap and feasible to be used for this purpose. Aliquots of diluted molasses, after a...

متن کاملThe Dependency of Colorimetric Characteristics of Black Fabrics to the Whiteness Attribute of Substrate
In this paper the effect of whiteness attribute of white substrates on blackness property of black coated fabrics is investigated. To this aim, four cotton fabrics with different whiteness and tint attributes are used as white substrates. To prepare a set of black samples, various concentrations of four color pigments, i.e., red, green, blue and yellow, were mixed with the black one and applied...
متن کاملA Recolouring Problem on Undirected Graphs
We consider an algorithm on a graph G = (V,E) with a 2-colouring of V , that is motivated from the computer-aided text-recognition. Every vertex changes simultaneously its colour if more than a certain proportion c of its neighbours have the other colour. It is shown, that by iterating this algorithm the colouring becomes either constant or 2-periodic. For c = 1 2 the presented theorem is a spe...
متن کاملUsing Color Visual Cryptography Schemes and Watermarking for Sharing Black and White Secret Images
Visual cryptography is a new secure technology that distributes a secret image by separating it into a number of shares using different visual cryptography schemes (VCS). Early VCS schemes mainly focused on black-and-white secret images. Using a black & white VCS normally degrade the image quality and also suffered from a major drawback of pixel expansion, which means that the size of each secr...
