the notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. the extensionproperty for (fuzzy) absorbent orderedfilters is established. conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...

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 twome...

Biofilters (BFs) and biotrickling filters (BTFs) are two types of bioreactors used for treatment volatile organic compounds (VOCs). Both BFs BTFs use packing materials in which various microorganisms immobilised. The water phase is stationary to maintain the humidity materials, while have a mobile liquid phase. Optimisation irrigation crucial effective performance BTFs. A literature review pres...
