in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twomechanisms s...

Ceramic foam filters (CFFs) are used to remove inclusions and/or solid particles from molten metal. In general, the metal poured on top of a CFF should reach certain height form pressure (metal head) required prime filter. For estimating head and obtaining permeability coefficients CFFs, experiments essential. Recently, electromagnetic priming filtration aluminum with low high grades CFF, i.e.,...

Abstract The population density of dwarf galaxies in low-density voids is likely determined by the dark matter halo mass function and how galaxy formation proceeds smaller halos. This depends on nature itself, making a tracer its properties. While dwarfs have been found smaller, closer voids, they proven difficult to find larger, more distant through magnitude-limited spectroscopic surveys. bec...

annihilation or reduction of each kind of noise blended in correct data signals is a field that has attracted many researchers. it is a fact that fuzzy theory presents full capability in this field. fuzzy filters are often strong in smoothing corrupted signals, whereas they have simple structures. in this paper, a new powerful yet simple fuzzy procedure is introduced for sharpness reduction in ...
