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