— Various model parameter calculation equations of RF CMOS inductors are compared. The calculation equations are using as variables either Y, Z-parameters or S-parameters. Results are based on on-wafer RF S-parameter measurements of a 3.75 turn spiral inductor fabricated in AMIS 0.7 μm CMOS DM1P n-well technology. Results obtained with calculation equations for a differentially driven inductor ...

Protein contact maps are representations of the proteins three dimensional folding topology. A fuzzy generalization of contact maps (FGCM) provides to the researcher flexibility not present in standard (i.e. crisp) contact maps but it also changes the information content of the data. To aid in the rationale –rather than ad-hocselection of generalized contact maps parameters we introduce some un...

mtbe (methyl tertiary-butyl ether) is an oxygenated organic matter which is widely used nowadays in some countries in unleaded gasoline. mtbe is a toxic substance which is absorbed quickly on water and soil and is one of the most important pollutants in soils and groundwater resources. in order to remove mtbe from the soil, using different experimental methods, determining reliable methods for ...

conclusions the study results showed that by increasing the initial dye concentration and contact time, the adsorption capacity increased, as well. moreover, the thermodynamic parameters (δh °, δg °, and δs °) revealed the endothermic sorption of rr-198 onto mwcnts. results the rr-198 absorption rates were 33.26 and 222.88 mg/g, respectively for 20, and 200 mg/l dye concentration, at ph of 3, 6...

introduction: arsenic is known as a carcinogenic compound in drinking water . it can cause acute and chronic effects on human health. in this study, the effect of polyamidoamine dendrimer generation 3(pamam g3) as adsorbents for removal of arsenic (v) from aqueous solutions was evaluated.     methods: adsorption experiment was studied in batch system and the effect of different variables like p...

We develop a covariance-matrix-based uncertainty analysis for vector-network-analyzer scattering-parameter measurements. The covariance matrix captures all of the measurement uncertainties and statistical correlations between them. This allows the uncertainties of vector-network-analyzer scattering-parameter measurements to be propagated into the uncertainties of other quantities derived from s...
