Perhaps you should try some spelling variations:
"advanced modulation in computer program" » "advanced calculation in computer program" (Expand search), "advanced oxidation in computer program" (Expand search), "advanced modulation of computer program" (Expand search), "advanced modulation _ computer program" (Expand search)
"and computational java computer program" » "and computacional java computer program" (Expand search), "and computational data computer program" (Expand search), "and computational and computer program" (Expand search), "_ computational java computer 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: "((\"and computational java computer program\") OR (\"advanced modulation in computer program\"))~".
• Removing quotes may allow a broader search: (( and computational java computer program ) OR ( advanced modulation in computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational java computer program") OR ("advanced modulation in computer program"))*.
