Perhaps you should try some spelling variations:
"using computational by computer program" » "and computational by computer program" (Expand search), "using computational _ computer program" (Expand search), "using computational 3d computer program" (Expand search), "using computational 3 computer program" (Expand search), "using computational and computer program" (Expand search)
"applying computational grid computing program" » "applying computational grids computing program" (Expand search), "applying computational and computing program" (Expand search), "applying computational art computing program" (Expand search), "applying computational grid consulting program" (Expand search), "applying computational grid computador program" (Expand search), "applying computational grid computer programs" (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: "((\"using computational by computer program\") OR (\"applying computational grid computing program\"))~".
• Removing quotes may allow a broader search: (( using computational by computer program ) OR ( applying computational grid computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational by computer program") OR ("applying computational grid computing program"))*.
