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