Perhaps you should try some spelling variations:
"_ convolutional coding on program" » "_ convolutional codes on program" (Expand search), "_ convolutional code on program" (Expand search), "_ convolutional long on program" (Expand search), "_ convolutional coding of program" (Expand search), "_ convolutional coding in program" (Expand search), "_ convolutional coding an program" (Expand search)
"field visualization python python programming" » "field visualization method python programming" (Expand search), "field visualization methods python programming" (Expand search), "field visualization tool python programming" (Expand search), "speed visualization python python programming" (Expand search), "direct visualization python python programming" (Expand search), "and visualization python python programming" (Expand search), "field visualization pythons python programming" (Expand search), "field visualization piton python programming" (Expand search), "field visualization pitons python programming" (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 on program") OR ("field visualization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional coding on program\") OR (\"field visualization python python programming\"))*".
• Removing quotes may allow a broader search: (( _ convolutional coding on program ) OR ( field visualization python python programming ))*.
