Perhaps you should try some spelling variations:
computations using » computation using (Expand search), populations using (Expand search), computations in (Expand search)
modeling vpython » modeling method (Expand search)
during modeling » using modeling (Expand search), drying modeling (Expand search), drying modelling (Expand search)
pulsed program » based program (Expand search), led program (Expand search), prored program (Expand search)
vpython python » python python (Expand search), pythons python (Expand search), piton python (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( AND computations using pulsed program ) OR ( during modeling vpython python programming ))*.
