Perhaps you should try some spelling variations:
"using computational using sampling program" » "and computational using sampling program" (Expand search), "using computation using sampling program" (Expand search), "using computations using sampling program" (Expand search), "using computacional usinas sampling program" (Expand search), "using computational using labeling program" (Expand search), "using computational using smoking program" (Expand search), "using computational using jumping program" (Expand search), "using computational using subsampling program" (Expand search), "using computational using saline program" (Expand search), "using computational using samples program" (Expand search)
"using modis from python programming" » "using mobile from python programming" (Expand search), "using modis from pathogen programming" (Expand search), "using modis from anthony programming" (Expand search), "using modes from python programming" (Expand search), "using mods from python programming" (Expand search), "using models from python programming" (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: "((\"using computational using sampling program\") OR (\"using modis from python programming\"))~".
• Removing quotes may allow a broader search: (( using computational using sampling program ) OR ( using modis from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational using sampling program") OR ("using modis from python programming"))*.
