Many users of open-source software are frightened by the term “derivative works”. They worry they might accidentally create derivative works and put their own proprietary software under an open-source ...
Well test analyses that include the first and second derivative of pressure plotted on a semilog scale can help detect radial flow. Plots of pressure data from short transient tests often fail to ...
Proportional-integral-derivative (PID) is the most common industrial technology for closed-loop control. A proportional-integral-derivative (PID) controller can be used to control temperature, ...
