Perhaps you should try some spelling variations:
"_ convolutional coding using programs" » "_ convolutional codes using programs" (Expand search), "_ convolutional code using programs" (Expand search), "_ convolutional long using programs" (Expand search), "_ convolutional coding using program" (Expand search), "_ convolutional coding housing programs" (Expand search), "_ convolutional coding nursing programs" (Expand search), "_ convolutional loading using programs" (Expand search), "_ convolutional modeling using programs" (Expand search), "_ convolutional drying using programs" (Expand search)
"surface application from python programming" » "surface modification from python programming" (Expand search), "surface applications from python programming" (Expand search), "surface application form python programming" (Expand search), "surface application forms python programming" (Expand search), "surface application from pathogen programming" (Expand search), "surface application from anthony 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 coding using programs\") OR (\"surface application from python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding using programs ) OR ( surface application from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding using programs") OR ("surface application from python programming"))*.
