the machine made carpet industry is one of the main and most famous industries in iran and especially in the city of yazd. however there is little information about customer preferences for different attributes of this product. in this article we tried to estimate the relative importance of the main attributes affecting customer desire for purchasing machine made carpet and the utility values f...

background: most rural carpet weaving workshops are part of the house and sanitary conditions of the workshop not only affect the weaving but also other family members this study aimed to determine the aerosol and bioaerosols concentration in the rural household carpet weaving workshops in isfahan. methods: in this this study is a cross - sectional study and was performed in 92 rural household ...

Carpeting can be found throughout various buildings, whether residential or commercial. This carpeting can be very useful to forensic scientists, especially when biological samples are present on it. However, obtaining high quality DNA profiles from this potential piece of evidence can be challenging due to the presences of Polymerase Chain Reaction (PCR) inhibitors that will interfere with the...

We study the orthogonal projections of a large class of self-affine carpets, which contains the carpets of Bedford and McMullen as special cases. Our main result is that if Λ is such a carpet, and certain natural irrationality conditions hold, then every orthogonal projection of Λ in a non-principal direction has Hausdorff dimension min(γ, 1), where γ is the Hausdorff dimension of Λ. This gener...

In 1836 Henry Fox Talbot, an inventor of photography, published the results of some experiments in optics that he had previously demonstrated at a British Association meeting in Bristol. "It was very curious to observe that though the grating was greatly out of the focus of the lens...the appearance of the bands was perfectly distinct and well defined...the experiments are communicated in the h...

It is shown that the homeomorphism groups of the (generalized) Sierpiński carpet and the universal Menger continua are not zero-dimensional. These results were corollaries to a 1966 theorem of Brechner. New proofs were needed because we also show that Brechner’s proof is inadequate. The method by which we obtain our results, the construction of closed imbeddings of complete Erdős space in the h...

We construct a Sierpinski carpet E ⊂ R of area zero and a K0 > 1 with the property that every K0-quasiconformal image of E contains rectifiable curves, but such that E has some quasiconformal image containing no non-constant rectifiable curves. 1991 Mathematics Subject Classification.
