Perhaps you should try some spelling variations:
"advanced computation and computer program" » "advanced computations and computer program" (Expand search), "advanced computational and computer program" (Expand search), "advance computational and computer program" (Expand search), "advanced computation of computer program" (Expand search), "advanced computation _ computer program" (Expand search)
"active sampling in computing program" » "active sampling in consulting program" (Expand search), "active sampling in computador program" (Expand search), "active sampling in computer programs" (Expand search), "passive sampling in computing program" (Expand search), "active sampling and computing program" (Expand search), "active sampling _ computing program" (Expand search), "active sampling 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: "((\"active sampling in computing program\") OR (\"advanced computation and computer program\"))~".
• Removing quotes may allow a broader search: (( active sampling in computing program ) OR ( advanced computation and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("active sampling in computing program") OR ("advanced computation and computer program"))*.
