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