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