Perhaps you should try some spelling variations:
"and computational python arduino programmable" » "and computacional python arduino programmable" (Expand search), "and computacional vpython arduino programmable" (Expand search), "and computacionais python arduino programmable" (Expand search), "_ computational python arduino programmable" (Expand search)
"using opencl python python programming" » "using opencv python python programming" (Expand search), "using opencl pythons python programming" (Expand search), "using opencl piton python programming" (Expand search), "using opencl pitons python programming" (Expand search), "using open python python programming" (Expand search), "using optical python 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: (("and computational python arduino programmable") OR ("using opencl python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational python arduino programmable\") OR (\"using opencl python python programming\"))".
• Removing quotes may allow a broader search: (( and computational python arduino programmable ) OR ( using opencl python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("and computational python arduino programmable") OR ("using opencl python python programming"))*.
