Talvez deva tentar algumas variações de ortografia:
tracking python » teaching python (Expandir a busca), tracking method (Expandir a busca), tracking position (Expandir a busca)
computation by » computation of (Expandir a busca), computation _ (Expandir a busca), computation in (Expandir a busca)
pulsed program » based program (Expandir a busca), led program (Expandir a busca), prored program (Expandir a busca)
using tracking » using stacking (Expandir a busca), using ranking (Expandir a busca), using brackish (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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