Perhaps you should try some spelling variations:
"using computational in computer program" » "and computational in computer program" (Expand search), "using computational and computer program" (Expand search), "using computational _ computer program" (Expand search), "using computational 3d computer program" (Expand search)
"advanced modulation code convex programming" » "advanced calculation code convex programming" (Expand search), "advanced oxidation code convex programming" (Expand search), "advanced modulation code cone programming" (Expand search), "advanced modulation code computer programming" (Expand search), "advanced modulation codes convex programming" (Expand search), "advanced modulation model convex programming" (Expand search), "advanced modulation doped convex programming" (Expand search), "advanced modulation some convex programming" (Expand search), "advanced modulation closed convex programming" (Expand search), "advanced modulation code concept 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: "((\"using computational in computer program\") OR (\"advanced modulation code convex programming\"))~".
• Removing quotes may allow a broader search: (( using computational in computer program ) OR ( advanced modulation code convex programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational in computer program") OR ("advanced modulation code convex programming"))*.
