Perhaps you should try some spelling variations:
"distributed simulation python python programming" » "distributed generation python python programming" (Expand search), "distributed simulation method python programming" (Expand search), "distributed simulation methos python programming" (Expand search), "distributed simulacao python python programming" (Expand search), "distributed simulation pythons python programming" (Expand search), "distributed simulation piton python programming" (Expand search), "distributed simulation pitons python programming" (Expand search)
"_ convolutional coding and program" » "_ convolutional codes and program" (Expand search), "_ convolutional code and program" (Expand search), "_ convolutional long and program" (Expand search), "_ convolutional coding and programs" (Expand search), "_ convolutional coding grant program" (Expand search), "_ convolutional coding based program" (Expand search), "_ convolutional coding rna program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ convolutional coding and program") OR ("distributed simulation python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional coding and program\") OR (\"distributed simulation python python programming\"))*".
• Removing quotes may allow a broader search: (( _ convolutional coding and program ) OR ( distributed simulation python python programming ))*.
