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)
"advanced modulation methods coding program" » "advanced calculation methods coding program" (Expand search), "advanced oxidation methods coding program" (Expand search), "advanced modulation method coding program" (Expand search), "advanced population methods coding program" (Expand search), "advanced inoculation methods coding program" (Expand search), "advanced modulation methods aiding program" (Expand search), "advanced modulation methods voting program" (Expand search), "advanced modulation methods coupling program" (Expand search), "advanced modulation methods cloning program" (Expand search), "advanced modulation methods loading program" (Expand search), "advanced modulation methods cooling 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: "((\"advanced modulation methods coding program\") OR (\"based computational and computer program\"))~".
• Removing quotes may allow a broader search: (( advanced modulation methods coding program ) OR ( based computational and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation methods coding program") OR ("based computational and computer program"))*.
