Perhaps you should try some spelling variations:
"_ convolutional code using project" » "_ convolutional codes using project" (Expand search), "_ convolutional and using project" (Expand search), "_ convolucional cnn using project" (Expand search), "_ convolutional code housing project" (Expand search), "_ convolutional code housing projects" (Expand search), "_ convolutional code mining project" (Expand search), "_ convolutional made using project" (Expand search), "_ convolutional coding using project" (Expand search)
"advanced oxidation and python programming" » "advanced oxidation in python programming" (Expand search), "advanced oxidation on python programming" (Expand search), "advanced oxidation api 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 using project\") OR (\"advanced oxidation and python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional code using project ) OR ( advanced oxidation and python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional code using project") OR ("advanced oxidation and python programming"))*.
