Perhaps you should try some spelling variations:
"advanced computation and computer program" » "advanced computations and computer program" (Expand search), "advanced computational and computer program" (Expand search), "advance computational and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"advanced modulation code code programming" » "advanced calculation code code programming" (Expand search), "advanced oxidation code code programming" (Expand search), "advanced modulation code cone programming" (Expand search), "advanced modulation code core programming" (Expand search), "advanced modulation code co programming" (Expand search), "advanced modulation codes code programming" (Expand search), "advanced modulation model code programming" (Expand search), "advanced modulation doped code programming" (Expand search), "advanced modulation code cdc programming" (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 computation and computer program\") OR (\"advanced modulation code code programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation and computer program ) OR ( advanced modulation code code programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and computer program") OR ("advanced modulation code code programming"))*.
