Perhaps you should try some spelling variations:
"based computational and computer program" » "and computational and computer program" (Expand search), "by computational and computer program" (Expand search), "based computational fluid computer program" (Expand search), "based computational _ computer program" (Expand search)
"using computational cloud computing program" » "and computational cloud computing program" (Expand search), "using computational clouds computing program" (Expand search), "using computational blood computing program" (Expand search), "using computational cost computing program" (Expand search), "using computational cloud consulting program" (Expand search), "using computational cloud computador program" (Expand search), "using computational cloud computer programs" (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: (("based computational and computer program") OR ("using computational cloud computing program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computational and computer program\") OR (\"using computational cloud computing program\"))".
• Removing quotes may allow a broader search: (( based computational and computer program ) OR ( using computational cloud computing program )).
• Adding a wildcard symbol may retrieve word variants: (("based computational and computer program") OR ("using computational cloud computing program"))*.
