Perhaps you should try some spelling variations:
"and computation in diffusion program" » "and computation in diffusion problem" (Expand search), "and computation in diffusion problems" (Expand search), "and computation in diffusion process" (Expand search), "and computational in diffusion program" (Expand search), "of computation in diffusion program" (Expand search), "and computation and diffusion program" (Expand search), "and computation of diffusion program" (Expand search), "and imputation in diffusion program" (Expand search), "and computation on diffusion program" (Expand search), "and computation _ diffusion program" (Expand search)
"using modulo python python programming" » "using codigo python python programming" (Expand search), "using modulo pythons python programming" (Expand search), "using modulo piton python programming" (Expand search), "using modulo pitons python programming" (Expand search), "using module python python programming" (Expand search), "using model python python programming" (Expand search), "using models 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 in diffusion program\") OR (\"using modulo python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation in diffusion program ) OR ( using modulo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation in diffusion program") OR ("using modulo python python programming"))*.
