The lattice fractal Sierpinski carpet and the percolation theory are applied to develop a new random stock price for the financial market. Percolation theory is usually used to describe the behavior of connected clusters in a random graph, and Sierpinski carpet is an infinitely ramified fractal. In this paper, we consider percolation on the Sierpinski carpet lattice, and the corresponding finan...

Visual-spatial impairment is a fundamental disorder in cerebral palsy (CP). However, current spatial testing is restricted to reaching space, whereas navigational space is seldom assessed. The Magic Carpet test, derived from the Corsi Block-tapping Task (CBT) for visual-spatial memory, is a new developmental test for navigation. The performances of the Magic Carpet test and CBT were assessed in...

42-year-old woman experienced an acute asthma attack, seizures, and unconsciousness immediately after a carpet-cleaning and deodorizing job was conducted in her home. Exposure modeling estimates that she was exposed to approximately 3.4-17 mg/m(3) of sodium tripolyphosphate and more than 14 mg/m(3) volatile organic compounds immediately after the cleaning. I derived two separate exposure models...

Persian is one of the Indo-European languages which has borrowed its script from Arabic, a member of Semitic language family. Since Persian and Arabic scripts are so similar, problems arise when we want to process an electronic text. In this paper, some of the common problems faced experimentally in developing a corpus for Persian are discussed. The sources of the problems are the Persian scrip...

The Persian language is one of the dominant languages in the Middle East, so there are significant amount of Persian documents available on the Web. Due to the special and different nature of the Persian language compared to other languages like English, the design of information retrieval systems in Persian requires special considerations. However, there are relatively few studies on retrieval...

Persian is an Indo-European language written using Arabic script, and is an official language of Iran, Afghanistan, and Tajikistan. Transliteration of Persian to English—that is, the character-bycharacter mapping of a Persian word that is not readily available in a bilingual dictionary—is an unstudied problem. In this paper we make three novel contributions. First, we present performance compar...

Three typical kinds of building materials (painted drywall, ceiling tile, and carpet) have been tested to study the effects of environmental conditions (temperature, relative humidity, and air velocity) on the sorption of volatile organic compounds (VOCs) by building materials. It was found that the effects of environmental conditions on sorption were insignificant for the painted drywall due t...
