Experiment design to achieve desired statistical power

Optimal Source Impedance to Trade-Off Power and Noise and to Achieve a Desired S11

In the design of a low noise amplifier,LNA, or mixer driver stage there exists an optimal source source impedance to provide the maximum power transfer into the transistor and thus the maximum gain. There also exists an optimal source impedance, Znopt, to provide the minimum noise figure for the circuit. At the maximum power source impedance, Zpopt, the input is matched to the source impedance ...

A Sensemaking Experiment – Enhanced Reasoning Techniques to Achieve Cognitive Precision

The purpose of this research was to conduct a pilot study of techniques from Klein Associates and Cognitive Edge to improve military sensemaking, specifically in the area of Cognitive Precision – FSD defines it as the “collection and connection of the right dots”, i.e. relevant data. Several obstacles to cognitive precision were identified in the areas of seeing information (info overload, patt...

Voltage waveform to achieve a desired ion energy distribution on a substrate in contact with plasma

A methodology is developed to determine the bias voltage waveform needed to achieve a desired (pre-selected) ion energy distribution (IED) on a substrate in contact with plasma. The approach is applicable to collisionless sheaths at all radio frequencies. It combines a circuit model with an equation for a ‘damped’ sheath potential to which ions respond. The methodology is demonstrated by comput...

Analytical Solution for Speed to Achieve a Desired Operating Point for a given Fan or Pump

The Affinity Laws for fans (and pumps) provide a way of determining new fan or pump speed given fan or pump performance curve data and a desired operating point (combination of flow rate and pressure) that does not fall on the curve. However, the affinity law calculations require using a point on the curve (hereafter referred to as the “basic point”) to determine the new speed. Most references ...
