Perhaps you should try some spelling variations:
"service applications in python programming" » "service application in python programming" (Expand search), "device applications in python programming" (Expand search), "service implications in python programming" (Expand search), "service applications _ python programming" (Expand search)
"2d convolutional codes using program" » "3d convolutional codes using program" (Expand search), "and convolutional codes using program" (Expand search), "of convolutional codes using program" (Expand search), "2d convolutional codes housing program" (Expand search), "2d convolutional codes nursing program" (Expand search), "2d convolutional codes aging program" (Expand search), "2d convolutional code using program" (Expand search), "2d convolutional nodes using program" (Expand search), "2d convolutional modes using program" (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: "((\"2d convolutional codes using program\") OR (\"service applications in python programming\"))~".
• Removing quotes may allow a broader search: (( 2d convolutional codes using program ) OR ( service applications in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("2d convolutional codes using program") OR ("service applications in python programming"))*.
