Perhaps you should try some spelling variations:
"advanced modulation of computer program" » "advanced calculation of computer program" (Expand search), "advanced oxidation of 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 of computer program") OR ("advanced simulation grid computational program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced modulation of computer program\") OR (\"advanced simulation grid computational program\"))".
• Removing quotes may allow a broader search: (( advanced modulation of computer program ) OR ( advanced simulation grid computational program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation of computer program") OR ("advanced simulation grid computational program"))*.
