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 code computation program" » "advanced calculation code computation program" (Expand search), "advanced oxidation code computation program" (Expand search), "advanced modulation code computational program" (Expand search), "advanced modulation code computational programs" (Expand search), "advanced modulation code compensation program" (Expand search), "advanced modulation core computation program" (Expand search), "advanced modulation pose computation program" (Expand search), "advanced modulation codes computation program" (Expand search), "advanced modulation model computation program" (Expand search), "advanced modulation doped computation 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 code computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation in computer program\") OR (\"advanced modulation code computation program\"))".
• Removing quotes may allow a broader search: (( advanced simulation in computer program ) OR ( advanced modulation code computation program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation in computer program") OR ("advanced modulation code computation program"))*.
