Perhaps you should try some spelling variations:
"_ convolutional coding radio program" » "_ convolutional codes radio program" (Expand search), "_ convolutional code radio program" (Expand search), "_ convolutional long radio program" (Expand search), "_ convolutional coding radio programas" (Expand search), "_ convolutional fading radio program" (Expand search), "_ convolutional coding region program" (Expand search), "_ convolutional reading radio program" (Expand search)
"advanced coding python python programming" » "advanced modeling python python programming" (Expand search), "advanced coatings python python programming" (Expand search), "advanced cutting python python programming" (Expand search), "advanced codigo python python programming" (Expand search), "advanced codigos python python programming" (Expand search), "advanced using python python programming" (Expand search), "advanced coding pythons python programming" (Expand search), "advanced coding piton python programming" (Expand search), "advanced coding pitons python programming" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional coding radio program\") OR (\"advanced coding python python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding radio program ) OR ( advanced coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding radio program") OR ("advanced coding python python programming"))*.
