Talvez deva tentar algumas variações de ortografia:
computations using » populations using (Expandir a busca), computations in (Expandir a busca), communications using (Expandir a busca)
pulsed program » based program (Expandir a busca), led program (Expandir a busca), prored program (Expandir a busca)
modern vpython » modeling vpython (Expandir a busca)
vpython python » python python (Expandir a busca), pythons python (Expandir a busca), piton python (Expandir a busca)
using modern » using model (Expandir a busca), using modis (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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