Perhaps you should try some spelling variations:
"and computation using active programming" » "and computation using reactive programming" (Expand search), "and computation using octave programming" (Expand search), "and computation using adaptive programming" (Expand search), "and computations using active programming" (Expand search), "and computation in active programming" (Expand search), "and composition using active programming" (Expand search), "and computational using active programming" (Expand search), "of computation using active programming" (Expand search)
"using tool python python programming" » "using tool pythons python programming" (Expand search), "using tool piton python programming" (Expand search), "using tool pitons python programming" (Expand search), "using tools python python programming" (Expand search), "using total python python programming" (Expand search), "using tonal python 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: "((\"and computation using active programming\") OR (\"using tool python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using active programming ) OR ( using tool python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using active programming") OR ("using tool python python programming"))*.
