Background and aims : With the increasing application of nanotechnology concerns about the negative effects of human exposure and environmental releases of these particles is also doubled. Among the most well-known media, ULPA filters are used to control nanoparticles. In this study, the efficiency and pressure drop of ULPA fiber bed for collection and removal of nanoparticles were investigat...
Photonic add-drop filters are crucial components for the implementation of wavelength division multiplexing (WDM) in fiber-optic communication systems. The recent progress photonic integration has shown potential to integrate alongside high-performance building blocks on a chip construct compact and complex photonic-integrated circuits WDM. Typically, implementations based micro-ring resonators...
Recent extensions to the Internet architecture allow assignment of different levels of drop precedence to IP packets. This paper examines differentiation predictability and implementation complexity in creation of proportional loss-rate (PLR) differentiation between drop precedence levels. PLR differentiation means that fixed loss-rate ratios between different traffic aggregates are provided in...
The uncapacitated facility location problem aims to select a subset of facilities to open, so that the demands of a given set of customers are satisfied at the minimum cost. In this study, we present a novel multistart Drop-Add-Swap heuristic for this problem. The proposed heuristic is multiple applications of the DropAdd-Swap heuristic with randomly generated initial solutions. And the propose...
the aim of this study was to evaluate the effect of evaporative media as gas turbine intake air cooling method on pressure drop of cartridge air filters. this study performed under the laboratory condition, using stainless steel test rig with specified dimensions to investigate the role of evaporative media in air cooling as well as its effects on new and used cartridge filters (as representati...
