Perhaps you should try some spelling variations:
"coder estimation using arduino programmable" » "model estimation using arduino programmable" (Expand search), "power estimation using arduino programmable" (Expand search), "order estimation using arduino programmable" (Expand search), "coder estimation in arduino programmable" (Expand search), "coder estimation and arduino programmable" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: (("coder estimation using arduino programmable") OR ("using in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder estimation using arduino programmable\") OR (\"using in python python programming\"))".
• Removing quotes may allow a broader search: (( coder estimation using arduino programmable ) OR ( using in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder estimation using arduino programmable") OR ("using in python python programming"))*.
