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