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...
Carpet experts consider nobility of a Qashqai rug in properties like use of suitable wool fiber, herbaceous dyeing, mental designing and bald painting. These principles were used in a variety of samples of Qashai tribe’s hand-woven carpets. On the other hand, production system in that period was based on the use of existing sources and facilities and motivated by providing financial suppo...
In this paper we present a novel 3D scanner to capture the texture characteristics of worn carpets into images of the depth. We first compare our proposed scanner to a Metris scanner previously attempted for this application. Then, we scan the surface of samples from the standard EN1471 using our proposed scanner. We found that our proposed scanner offers additional benefits because it has been...
Nowadays, the hand-woven carpet industry has lost its status in international market due to economic issues and international policy towards Iran, moving it into a slow deterioration. On the other hand, the domestic market of hand-woven carpet has recessed in a way that even those few shoppers can’t afford buying carpets. The hand-woven carpet market situation needs changes in cultural...
gabbeh is one type of different types of hand-woven carpets of qashqaei tribes (south and center of iran) which is woven by the women of these tribes. in fact this hand-woven rug is kind of carpet woven to be slef-consumed which was woven from old times with creative and subjective patterns in a two dimensional and abstract format. the patterns are taken from the nature and environment where th...
In the field of Iranian hand-woven rugs, there are different regions with varied histories some of which are still unknown or neglected. Among these are the Shariat-madar Hur rugs which belong to the ancient region of "Eij" and not long ago, were considered as unique masterpieces of carpet-weaving in Fars province. Definitely, one of the essential investigations in the field of hand-w...
Optimal texture analysis algorithms for describing degradation of carpets are identified. Experimental design is applied to select from a set of texture analysis algorithms those optimal for identifying texture changes due to degradation of carpets. The degree of wear of a degraded carpet is quantified by comparing its texture to the original texture. The set of texture algorithms is applied on...
We calculate the Assouad dimension of the self-affine carpets of Bedford and McMullen, and of Lalley and Gatzouras. We also calculate the conformal Assouad dimension of those carpets that are not self-similar.
BACKGROUND Falls are a leading cause of unintentional injury among adults age 65 years and older. Loose, unsecured rugs and damaged carpets with curled edges, are recognized environmental hazards that may contribute to falls. To characterize nonfatal, unintentional fall-related injuries associated with rugs and carpets in adults aged 65 years and older. METHODS We conducted a retrospective an...
