For washing of carpets, scrapping is done using a wooden plank. The edge of the plank gives pressure on the carpet to remove dirt particles and water from the carpet surface. The plank follows a straight-line path on the carpet surface. In this paper Hoeken’s and Pantograph mechanisms are used to obtain a straight-line path for carpet scrapping. Hoeken’s four-bar mechanism can produce the same ...

Cognitive deficits experienced by older adults with dementia limit use of wearable devices (necklaces or bracelets) that summon assistance after the older adult falls. To use these wearable devices, older adults must choose to wear them, remember how to use them, and be conscious after falling. Devices such as the Smart Carpet substitute pre-programmed or automatic functions for functions requi...

purpose : to determine the effect of carpet weaving on refractive errors methods : in this cross sectional study, carpet weavers and non-weavers in the normal population of mashhad were regarded as exposed and non-exposed groups, respectively. a carpet weaver was a person who wove carpets 7 hours a day for at least 2 years. the non-weavers group was selected from the population of mashhad throu...

the carpet industry developed various types of respiratory and musculoskeletal disorders, eyesight problems,  carpal tunnel syndrome and skin problems. healthy behavior of carpet weavers is not in a desirable level. we recommended appropriate interventions such as health service, education improvement and advocacy for promoting healthy behaviors of carpet weavers.

We have devised a thermal carpet cloak theoretically and implemented in silicon using layered metamaterial. The layered metamaterial is composed of single crystalline silicon and its phononic crystal. The design is based on a coordinate transformation. We demonstrate the result with numerical simulation. Great cloaking performance is achieved as a thermal insulator is well hidden under the ther...

We demonstrate in this work a unique approach for watching outside while hiding in a carpet cloaking based on transformation optics. Unlike conventional carpet cloaking, which screens all the incident electromagnetic waves, we break the cloak and allow incident light get into the carpet. Hence outside information is detected inside the cloak. To recover the invisible cloaking, complementary tec...

The carpet industry is one of the most rapidly growing traditional industries in India. This is a handicraft and cottage industry that provides jobs right at doorstep of more than 100,000 workers, belonging to economically backward class of society. In the global carpet scenerio, the market share of Indian carpets is expanding rapidly. Jaipur and its adjacent districts are the major manufacturi...

In this research, an apparatus was designed and constructed in order to simulate the storage behavior of hand-woven carpet under different environmental conditions. Silk hand-woven carpet (“Gom”) with 115×75 cm dimensions and 102×97 knot per 10 cm was selected and then inserted into the packing simulator with two different laying configurations including flat and folded....

• Polluted indoor air can lead to discomfort, reduced efficiency and even ill health amongst employees and residents in modern buildings. • Wool carpet has been shown to rapidly neutralize formaldehyde, nitrogen dioxide and sulphur dioxide, common contaminants in today's indoor environment. • Not only does wool neutralize these contaminants more quickly and completely than synthetic carpet fibe...
