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