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