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