A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

this survey was done for constructing an egg sorting machine which could sort white eggs from fertilized eggs. egg sorting machine was constructed based on physiological properties of trout egg. fertilized eggs have much more elasticity than white or non-hatched eggs. so the hatched eggs will fly back if were hit to a solid surface. the machine divided to 5 parts including mechanical, electrica...

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%),...
