Perhaps you should try some spelling variations:
"advanced simulation based computer program" » "advanced calculation based computer program" (Expand search), "advanced population based computer program" (Expand search), "advanced simulation and computer program" (Expand search), "advanced simulation based computing program" (Expand search), "advanced simulation board computer program" (Expand search), "advanced simulation cad computer program" (Expand search)
"advanced modulation and computer program" » "advanced calculation and computer program" (Expand search), "advanced oxidation and computer program" (Expand search), "advanced modulation in computer program" (Expand search), "advanced modulation of computer program" (Expand search), "advanced modulation _ computer program" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced simulation based computer program\") OR (\"advanced modulation and computer program\"))~".
• Removing quotes may allow a broader search: (( advanced simulation based computer program ) OR ( advanced modulation and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation based computer program") OR ("advanced modulation and computer program"))*.
