Perhaps you should try some spelling variations:
"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)
"advanced simulation grid computational program" » "advanced calculation grid computational program" (Expand search), "advanced simulation grid computacional program" (Expand search), "advanced simulation acid computational program" (Expand search), "advanced simulation grid computation program" (Expand search), "advanced simulation hybrid computational program" (Expand search), "advanced simulation guided computational program" (Expand search), "advanced simulation and computational program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced modulation in computer program") OR ("advanced simulation grid computational program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced modulation in computer program\") OR (\"advanced simulation grid computational program\"))".
• Removing quotes may allow a broader search: (( advanced modulation in computer program ) OR ( advanced simulation grid computational program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation in computer program") OR ("advanced simulation grid computational program"))*.
