Perhaps you should try some spelling variations:
"using computational coder detection problem" » "and computational coder detection problem" (Expand search), "using computational code detection problem" (Expand search), "using computational codes detection problem" (Expand search), "using computational model detection problem" (Expand search), "using computational coder selection problem" (Expand search), "using computational coder detection program" (Expand search), "using computational coder demarcation problem" (Expand search), "using computational border detection problem" (Expand search), "using computational corner detection problem" (Expand search)
"sensor using python python programming" » "sensor using pythons python programming" (Expand search), "sensor using piton python programming" (Expand search), "sensor using pitons python programming" (Expand search), "sensors using python python programming" (Expand search), "sensor fusion python python programming" (Expand search), "sensor usando python python programming" (Expand search), "sensor in python python programming" (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: (("using computational coder detection problem") OR ("sensor using python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational coder detection problem\") OR (\"sensor using python python programming\"))*".
• Removing quotes may allow a broader search: (( using computational coder detection problem ) OR ( sensor using python python programming ))*.
