We consider a random version of the McMullen–Bedford general Sierpinski carpet which is constructed by randomly choosing patterns in each step instead of a single pattern in its original form. Their Hausdorff, packing and box-counting dimensions are determined. A sufficient condition and a necessary condition for the Hausdorff measures in their dimensions to be positive are given. As an applica...

We consider the revival properties of quantum systems with an eigenspectrum En ∝ n, and compare them with the simplest member of this class – the infinite square well. In addition to having perfect revivals at integer multiples of the revival time tR, these systems all enjoy perfect fractional revivals at quarterly intervals of tR. A closer examination of the quantum evolution is performed for ...

Cellular automata can be used to design high-performance natural solvers on parallel computers. This paper describes the development of applications using CARPET, a high-level programming language based on the biology-inspired cellular automata theory. CARPET is a programming language designed for supporting the development of parallel high-performance software abstracting from the parallel arc...

the cost of drying carpet which is done toward the end of the manufacturing process, is quite high. the carpet industry has been using convection drying for many years. little attention has been given to quantifying the effect of microwave power during the drying of carpet. an experimental system was developed whereby air was introduced into the cavity of a domestic microwave oven. the results ...

ninteen samples of dust from wool and carpet-weaving places around tabriz were collected. dust mites of wool and carpet-weaving places were separated and identified based on morphological characteristics. genus and species of mites per gram of dusts, were determined. the results showed that dominant population of mites were:dermatophagoides farinae (64%), dermatophagoides pteronyssinus (21.5%),...

background: carpet weaving is an occupation that requires sufficient and appropriate lighting. the lighting in carpet weaving workshops affects the productivity and the physical and mental health of workers. therefore, the evaluation of the illumination and the identification of work stations requiring lighting modifications will be helpful in promotion of the health and safety of workers in ca...
