Perhaps you should try some spelling variations:
"based computation using sio2 array" » "based computational using sio2 array" (Expand search), "based competition using sio2 array" (Expand search), "based compilation using sio2 array" (Expand search), "based computations using sio2 array" (Expand search), "based computation in sio2 array" (Expand search), "based composition using sio2 array" (Expand search), "based computation using tio2 array" (Expand search), "based computation using six array" (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using sio2 array\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using sio2 array ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using sio2 array") OR ("using in python python programming"))*.
