Perhaps you should try some spelling variations:
"_ convolutional coding based program" » "_ convolutional codes based program" (Expand search), "_ convolutional code based program" (Expand search), "_ convolutional long based program" (Expand search), "_ convolutional coating based program" (Expand search), "_ convolutional modeling based program" (Expand search), "_ convolutional reading based program" (Expand search)
"advanced validation with python programming" » "advanced oxidation with python programming" (Expand search), "advanced glication with python programming" (Expand search), "advanced visualization with python programming" (Expand search), "advanced validation in python programming" (Expand search), "advanced validation method 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 based program") OR ("advanced validation with python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional coding based program\") OR (\"advanced validation with python programming\"))".
• Removing quotes may allow a broader search: (( _ convolutional coding based program ) OR ( advanced validation with python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding based program") OR ("advanced validation with python programming"))*.
