Talvez deva tentar algumas variações de ortografia:
modeling vpython » modeling method (Expandir a busca)
pulsed program » based program (Expandir a busca), led program (Expandir a busca), prored program (Expandir a busca)
using modeling » using model (Expandir a busca), using modern (Expandir a busca), using models (Expandir a busca)
vpython python » python python (Expandir a busca), pythons python (Expandir a busca), piton python (Expandir a busca)
of pulsed » of pulse (Expandir a busca), by pulsed (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( AND computation of pulsed program ) OR ( using modeling vpython python programming ))*.
