Given a simple polygon constructed on a grid of equal-distanced points (i.e., points with integer coordinates) such that all the polygon’s vertices ... more
In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input ... more
The Biot number (Bi) is a dimensionless quantity used in heat transfer calculations. Gives a simple index of the ratio of the heat transfer resistances ... more
The current gain can be calculated using current instead of power using Joule’s first law to calculate. In many cases, the input and output ... more
The power gain can be calculated using voltage instead of power using Joule’s first law to calculate a voltage gain. In many cases, the input and ... more
