Perhaps you should try some spelling variations:
"based computational _ computing program" » "and computational _ computing program" (Expand search), "by computational _ computing program" (Expand search), "based computational _ consulting program" (Expand search), "based computational _ computador program" (Expand search), "based computational _ computer programs" (Expand search)
"advanced modulation in computer program" » "advanced calculation in computer program" (Expand search), "advanced oxidation in computer program" (Expand search), "advanced modulation of computer program" (Expand search), "advanced modulation _ computer program" (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 computational _ computing program\") OR (\"advanced modulation in computer program\"))~".
• Removing quotes may allow a broader search: (( based computational _ computing program ) OR ( advanced modulation in computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational _ computing program") OR ("advanced modulation in computer program"))*.
