Perhaps you should try some spelling variations:
"_ convolutional coding in program" » "_ convolutional codes in program" (Expand search), "_ convolutional code in program" (Expand search), "_ convolutional long in program" (Expand search), "_ convolutional coding in programs" (Expand search), "_ convolutional coding rna program" (Expand search), "_ convolutional coding and program" (Expand search), "_ convolutional coding _ 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.

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