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 ...

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...

A set of growth arrest-specific (gas) genes negatively regulated by serum has been identified. We report the analysis of the expression of one of them (gas-i) in transformed cells. We found a down regulation of gas-I expression in NIH 3T3 cells transfected in vitro with an activated Ha-ras oncogene. In five chemically-induced mouse tumours grown in vivo the amounts of gas-I mRNA were largely di...

3 Paragraph 4, lines 3 and 4, p. 2911: For the following sentence citing reference [60], units should be in μg/(m h); not in mg/(m h). On an area basis, caulking has the highest emission rate, 310 μg m h, among materials tested, followed by carpet pads (installed underneath carpets), 2.1 to 9.9 μg m h. Emission rates fell below 1 μg m h for other materials tested, which included solid and engin...
