Perhaps you should try some spelling variations:
"_ convolutional code feeding program" » "_ convolutional codes feeding program" (Expand search), "_ convolutional and feeding program" (Expand search), "_ convolucional cnn feeding program" (Expand search), "_ convolutional chose feeding program" (Expand search), "_ convolutional care feeding program" (Expand search), "_ convolutional choice feeding program" (Expand search)
"advanced oxidation of python programming" » "advanced oxidation _ python programming" (Expand search), "advanced oxidation in 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 code feeding program\") OR (\"advanced oxidation of python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional code feeding program ) OR ( advanced oxidation of python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional code feeding program") OR ("advanced oxidation of python programming"))*.
