Perhaps you should try some spelling variations:
"practical validation in python programming" » "practical evaluation in python programming" (Expand search), "preclinical validation in python programming" (Expand search), "practical application in python programming" (Expand search), "practical validation and python programming" (Expand search), "practical validation of python programming" (Expand search), "practical validation _ python programming" (Expand search)
"3d convolutional coding decoding program" » "3d convolutional codes decoding program" (Expand search), "3d convolutional code decoding program" (Expand search), "3d convolutional long decoding program" (Expand search), "and convolutional coding decoding program" (Expand search), "of convolutional coding decoding program" (Expand search), "_ convolutional coding decoding program" (Expand search), "3d convolutional coding welcoming program" (Expand search), "3d convolutional coding deworming program" (Expand search), "3d convolutional coding feeding program" (Expand search), "3d convolutional encoding decoding program" (Expand search), "3d convolutional reading decoding program" (Expand search), "3d convolutional joint decoding 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: "((\"3d convolutional coding decoding program\") OR (\"practical validation in python programming\"))~".
• Removing quotes may allow a broader search: (( 3d convolutional coding decoding program ) OR ( practical validation in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("3d convolutional coding decoding program") OR ("practical validation in python programming"))*.
