Perhaps you should try some spelling variations:
"advanced computations using computer program" » "advanced computational using computer program" (Expand search), "advance computational using computer program" (Expand search), "advanced communications using computer program" (Expand search), "advanced computation using computer program" (Expand search), "advanced populations using computer program" (Expand search), "advanced computations in computer program" (Expand search)
"using mobile on python programming" » "using mobile an python programming" (Expand search), "using mobile of python programming" (Expand search), "using mobile only python programming" (Expand search), "using mobile in python programming" (Expand search), "using mobile _ 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: "((\"advanced computations using computer program\") OR (\"using mobile on python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computations using computer program ) OR ( using mobile on python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computations using computer program") OR ("using mobile on python programming"))*.
