the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...

PURPOSE The purpose of this study was to determine the usefulness of a new graphical method for evaluating gas exchange (GE), as applied to three common averaging techniques used during rest, exercise, and recovery in patients with congestive heart failure (CHF). METHODS Fifty patients' resting, exercise, and recovery GE graphs were evaluated using a new graphical method to determine oxygen c...

Parametric models for estimating network link delays with incomplete data that incorporate spatial correlation are formulated. Fast numerical methods for estimation of parameters and confidence intervals are derived. It is shown that including correlation in the model gives better model fit on sample data. Finally, certain results from graphical models are described, which can be applied in mod...
