Perhaps you should try some spelling variations:
modeling vpython » modeling method (Expand search)
computation in » computation and (Expand search), computation of (Expand search), imputation in (Expand search)
pulsed program » based program (Expand search), led program (Expand search), prored program (Expand search)
using modeling » using model (Expand search), using modern (Expand search), using models (Expand search)
vpython python » python python (Expand search), pythons python (Expand search), piton python (Expand search)
in pulsed » and pulsed (Expand search), by pulsed (Expand search), of pulsed (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( AND computation in pulsed program ) OR ( using modeling vpython python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( AND computation in pulsed program ) OR ( using modeling vpython python programming ))*.
