Perhaps you should try some spelling variations:
"advanced computation of computation program" » "advanced computations of computation program" (Expand search), "advanced computational of computation program" (Expand search), "advance computational of computation program" (Expand search), "advanced computation of computational program" (Expand search), "advanced computation of computational programs" (Expand search), "advanced computation of compensation program" (Expand search), "advanced computation the computation program" (Expand search)
"advanced modulation in computer program" » "advanced calculation in computer program" (Expand search), "advanced oxidation 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 computation of computation program\") OR (\"advanced modulation in computer program\"))~".
• Removing quotes may allow a broader search: (( advanced computation of computation program ) OR ( advanced modulation in computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation of computation program") OR ("advanced modulation in computer program"))*.
