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