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