Perhaps you should try some spelling variations:
"device applications in python programming" » "medicine applications in python programming" (Expand search), "mobile applications in python programming" (Expand search), "space applications in python programming" (Expand search), "device applications _ python programming" (Expand search)
"and convolutional codes cleaning programs" » "and conventional codes cleaning programs" (Expand search), "of convolutional codes cleaning programs" (Expand search), "_ convolutional codes cleaning programs" (Expand search), "and convolutional codes cleaning program" (Expand search), "and convolutional codes learning programs" (Expand search), "and convolutional codes screening programs" (Expand search), "and convolutional mode cleaning programs" (Expand search), "and convolutional forest cleaning programs" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("and convolutional codes cleaning programs") OR ("device applications in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and convolutional codes cleaning programs\") OR (\"device applications in python programming\"))".
• Removing quotes may allow a broader search: (( and convolutional codes cleaning programs ) OR ( device applications in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("and convolutional codes cleaning programs") OR ("device applications in python programming"))*.
