Perhaps you should try some spelling variations:
"model computational using java programming" » "models computational using java programming" (Expand search), "modelo computacional using java programming" (Expand search), "code computational using java programming" (Expand search), "model computation using java programming" (Expand search), "model computations using java programming" (Expand search), "model computacional usinas java programming" (Expand search), "model computational using and programming" (Expand search), "model computational using based programming" (Expand search), "model computational using goal programming" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: "((\"model computational using java programming\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( model computational using java programming ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("model computational using java programming") OR ("using in python python programming"))*.
