Perhaps you should try some spelling variations:
"advanced computations on computer program" » "advanced computational on computer program" (Expand search), "advance computational on computer program" (Expand search), "advanced communications on computer program" (Expand search), "advanced computations in computer program" (Expand search), "advanced computations of computer program" (Expand search), "advanced computation on computer program" (Expand search), "advanced computations en computer program" (Expand search), "advanced computations and computer program" (Expand search)
"advanced oxidation grid computation program" » "advanced oxidation grid computational program" (Expand search), "advanced oxidation grid computational programs" (Expand search), "advanced oxidation grid compensation program" (Expand search), "advanced oxidation grid computacional program" (Expand search), "advanced oxidation group computation program" (Expand search), "advanced oxidation graph computation program" (Expand search), "advanced oxidation acid computation program" (Expand search), "advanced oxidation lipid computation program" (Expand search), "advanced validation grid 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 computations on computer program") OR ("advanced oxidation grid computation program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computations on computer program\") OR (\"advanced oxidation grid computation program\"))".
• Removing quotes may allow a broader search: (( advanced computations on computer program ) OR ( advanced oxidation grid computation program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced computations on computer program") OR ("advanced oxidation grid computation program"))*.
