Perhaps you should try some spelling variations:
"dft calculation and computation program" » "dft calculation and computational program" (Expand search), "dft calculation and computational programs" (Expand search), "dft calculation and compensation program" (Expand search), "dft calculations and computation program" (Expand search), "cost calculation and computation program" (Expand search), "_ calculation and computation program" (Expand search), "dft calculation in computation program" (Expand search), "dft calculation of computation program" (Expand search)
"by computational in computing program" » "by computational in consulting program" (Expand search), "by computational in computer program" (Expand search), "by computational in computador program" (Expand search), "_ computational in computing program" (Expand search), "and computational in computing program" (Expand search), "by computational and computing program" (Expand search), "by computational _ computing program" (Expand search), "by computational 3d computing program" (Expand search), "by computational of computing 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: "((\"dft calculation and computation program\") OR (\"by computational in computing program\"))~".
• Removing quotes may allow a broader search: (( dft calculation and computation program ) OR ( by computational in computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("dft calculation and computation program") OR ("by computational in computing program"))*.
