Old carpets may be reservoirs of dust, lead (Pb), and dust mite allergen. The purpose of this study was to determine if the dust, Pb, dust mite allergen, bacteria, and fungi on the surface of carpets could be reduced by 90% in 1 week with the use of a Hoover Self Propelled Vacuum with Embedded Dirt Finder (HSPF). A high-volume surface sampler (HVS3) was used to measure surface dust and pollutan...
For the development of polymer carpets as active devices for micro- and nanotechnology, a control of the polymer carpet morphology and especially control of the stimulus responsive polymer brush is needed. Here, we report on the first example for the fabrication of patterned polymer carpets. On a two-dimensional framework of fully crosslinked and chemically patterned nanosheets, polymer brushes...
We consider a trace theorem for self-similar Dirichlet forms on self-similar sets to self-similar subsets. In particular, we characterize the trace of the domains of Dirichlet forms on the Sierpinski gaskets and the Sierpinski carpets to their boundaries, where boundaries mean the triangles and rectangles which confine gaskets and carpets. As an application, we construct diffusion processes on ...
Considering the art of Persian rug design as a computation creative design problem, with a vast domain space of possible design solutions that have aesthetic, cultural and historical considerations, we describe our dual stage genetic algorithm system for designing basic patterns of a specific type of Persian rugs. Our approach uses hard and soft design rules that we have been gleaned from the p...
The extensive developments of Iranian arts in Qajar era eventually led to pictorial representation in almost all forms of art. Carpet weaving was no exception too and during this era the so-called pictorial carpets emerged. Although the images of these carpets mostly appeared in the central field, the borders of the carpets also underwent drastic developments. The findings of this essay i...
Iranian carpets as a manifestation of Persian art, due to the capabilities of Islamic art, have been a context for epiphany of this art doctrine. Mehrabi carpets of the Golden Age of Persian carpet-waving arts, Safavid era, can br regarded as the flagship model in the manifestations of this art. These carpets often were woven with religious functions and to fulfill religious obligations. Korani...
Since 13th century (A.H.), we have been encountering the so-called pictorial rugs in Iran. These rugs have their own styles and sizes and reflect two major points: first, a kind of change in fabrication and consumption taste and second, the influence of other types of art and social reformations. Iranian pictorial rugs artists have designed and woven these rugs using themes such as ancient or c...
Today we know that the main reason for usage of calligraphy in carpet design was to state and explain the religious content instead of decorative role – such as the other Islamic functional arts. According to that, most of carpets that contain inscriptions are the Mihrabi Carpets that almost use for praying. Along with the Mihrabi Carpets that are often used in religious functions, calligraphy ...
