Perhaps you should try some spelling variations:
"advanced computation using subsampling program" » "advanced computations using subsampling program" (Expand search), "advanced computational using subsampling program" (Expand search), "advance computational using subsampling program" (Expand search), "advanced computation using sampling program" (Expand search), "advanced computation in subsampling program" (Expand search), "advanced composition using subsampling program" (Expand search), "advanced computation and subsampling program" (Expand search)
"using modis pym python programming" » "using mobile pym python programming" (Expand search), "using modis pytm python programming" (Expand search), "using modis tm python programming" (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 computation using subsampling program") OR ("using modis pym python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computation using subsampling program\") OR (\"using modis pym python programming\"))*".
• Removing quotes may allow a broader search: (( advanced computation using subsampling program ) OR ( using modis pym python programming ))*.
