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 and complexity program" » "advanced calculation and complexity program" (Expand search), "advanced oxidation and complexity program" (Expand search), "advanced modulation and complex program" (Expand search), "advanced modulation and complexity from" (Expand search), "advanced modulation and complexity priors" (Expand search), "advanced modulation in complexity program" (Expand search), "advanced modulation of complexity 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 computation program") OR ("advanced modulation and complexity program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation and computation program\") OR (\"advanced modulation and complexity program\"))".
• Removing quotes may allow a broader search: (( advanced simulation and computation program ) OR ( advanced modulation and complexity program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation and computation program") OR ("advanced modulation and complexity program"))*.
