Perhaps you should try some spelling variations:
"advanced computation using diffusion process" » "advanced computations using diffusion process" (Expand search), "advanced computational using diffusion process" (Expand search), "advance computational using diffusion process" (Expand search), "advanced computation in diffusion process" (Expand search), "advanced composition using diffusion process" (Expand search), "advanced computation using diffusion processes" (Expand search)
"using logic python python programming" » "using logic pythons python programming" (Expand search), "using logic piton python programming" (Expand search), "using logic pitons python programming" (Expand search), "using log python python programming" (Expand search), "using logistic python python programming" (Expand search), "using reologic 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: "((\"advanced computation using diffusion process\") OR (\"using logic python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using diffusion process ) OR ( using logic python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using diffusion process") OR ("using logic python python programming"))*.
