Perhaps you should try some spelling variations:
"advanced modulation and computer program" » "advanced calculation and computer program" (Expand search), "advanced oxidation and computer program" (Expand search), "advanced modulation in computer program" (Expand search), "advanced modulation of computer program" (Expand search), "advanced modulation _ computer program" (Expand search)
"using computational and coding program" » "and computational and coding program" (Expand search), "using computational fluid coding program" (Expand search), "using computational and cloning program" (Expand search), "using computational and loading program" (Expand search), "using computational and cooling programs" (Expand search), "using computational and coping program" (Expand search), "using computational and cooling program" (Expand search), "using computational and cooking 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: "((\"using computational and coding program\") OR (\"advanced modulation and computer program\"))~".
• Removing quotes may allow a broader search: (( using computational and coding program ) OR ( advanced modulation and computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational and coding program") OR ("advanced modulation and computer program"))*.
