Perhaps you should try some spelling variations:
"advanced computations _ computer program" » "advanced computational _ computer program" (Expand search), "advance computational _ computer program" (Expand search), "advanced communications _ computer program" (Expand search)
"using computational foot example of" » "and computational foot example of" (Expand search), "using computational cost example of" (Expand search), "using computational effort example of" (Expand search), "using computational blood example of" (Expand search), "using computational good example of" (Expand search), "using computational fit example of" (Expand search), "using computational first example of" (Expand search), "using computational foot sample of" (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 computations _ computer program\") OR (\"using computational foot example of\"))~".
• Removing quotes may allow a broader search: (( advanced computations _ computer program ) OR ( using computational foot example of ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computations _ computer program") OR ("using computational foot example of"))*.
