Perhaps you should try some spelling variations:
"advanced visualization in computer program" » "and visualization in computer program" (Expand search), "based visualization in computer program" (Expand search), "advanced simulation in computer program" (Expand search), "advanced visualization and computer program" (Expand search), "advanced visualization of computer program" (Expand search), "advanced visualization _ computer program" (Expand search)
"advanced modulation based coding program" » "advanced calculation based coding program" (Expand search), "advanced oxidation based coding program" (Expand search), "advanced population based coding program" (Expand search), "advanced modulator based coding program" (Expand search), "advanced formulation based coding program" (Expand search), "advanced modulation based cloning program" (Expand search), "advanced modulation based loading program" (Expand search), "advanced modulation based cooling programs" (Expand search), "advanced modulation based costing program" (Expand search), "advanced modulation based coating program" (Expand search), "advanced modulation based coatings program" (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 modulation based coding program\") OR (\"advanced visualization in computer program\"))~".
• Removing quotes may allow a broader search: (( advanced modulation based coding program ) OR ( advanced visualization in computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation based coding program") OR ("advanced visualization in computer program"))*.
