Research on Indoor Positioning Algorithm Based on Trilateral Positioning and Taylor Series Expansion
abstract background: the aim of this study was to compare the efficiency of conventional slow sand filter with modified filter bed with crushed recycled glass in removing of turbidity and total and fecal coliforms from water resources. methods: in this study efficiency of conventional slow sand filter and modified filter bed with crushed recycled glass during 4 months was compared and their p...
This paper presents a low loss and high selective lowpass filter which is implemented using suspended stripline (SSL) technology. The proposed structure is comprised of a 13th order generalized Chebyshev lowpass filter which enjoys integrated waveguide-to-SSL transitions. This filter is designed and fabricated to be used as lowpass channel of a U-band diplexer employed in frontend of a U-band d...
background: butterworth, gaussian, hamming, hanning, and parzen are commonly used spect filters during filtered back-projection (fbp) reconstruction, which greatly affect the quality and size accuracy of image. materials and methods: this study involved a cardiac phantom in which 1.10 cm thick cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc conc...
