Perhaps you should try some spelling variations:
"based computational using diffusion problems" » "and computational using diffusion problems" (Expand search), "by computational using diffusion problems" (Expand search), "based computation using diffusion problems" (Expand search), "based computations using diffusion problems" (Expand search), "based computacional usinas diffusion problems" (Expand search), "based computational using diffusion problem" (Expand search), "based computational using diffusion process" (Expand search)
"using module python python programming" » "using modulo python python programming" (Expand search), "using module method python programming" (Expand search), "using module pythons python programming" (Expand search), "using module piton python programming" (Expand search), "using module pitons python programming" (Expand search), "housing module python python programming" (Expand search), "using mobile python python programming" (Expand search), "using model 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: "((\"based computational using diffusion problems\") OR (\"using module python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using diffusion problems ) OR ( using module python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using diffusion problems") OR ("using module python python programming"))*.
