— 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 ...

Fifteen years after the term ‘ecohydrology’ came into use to describe integrative research spanning the two parent disciplines, we discuss methodological traditions of the parent disciplines and assess trends in the methodologies utilized in the young hybrid field of ecohydrology. In particular, we explore whether the marriage between the disciplines is built on a marriage of methodological str...

[1] Water is a key resource in determining the composition and structure of savanna ecosystems. In this study we present a simple cellular automata model in which death and reproduction chances of trees and grasses are based on the dynamical description of plant water stress by a probabilistic ecohydrological point model, using the parameterization for a Texas savanna. The results show that the...

With the implementation of water-conservation projects in Hetao Irrigation District (HID), great changes have taken place ecohydrological process. A cultivated land–wasteland–lake system upper Yellow River Basin (YRB) was chosen to study soil salt and water transport process with Hydrus-1D model. The model parameters were calibrated validated by measuring data. Measured values good agreement si...

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...
