Perhaps you should try some spelling variations:
"advanced modulation in computation program" » "advanced modulation in computational program" (Expand search), "advanced modulation in computational programs" (Expand search), "advanced modulation in compensation program" (Expand search), "advanced calculation in computation program" (Expand search), "advanced oxidation in computation program" (Expand search), "advanced modulation on computation program" (Expand search), "advanced modulation and computation program" (Expand search), "advanced modulation of computation program" (Expand search)
"by computational code computer program" » "by computational model computer program" (Expand search), "by computational cost computer program" (Expand search), "by computational models computer program" (Expand search), "_ computational code computer program" (Expand search), "and computational code computer program" (Expand search), "by computational node computer program" (Expand search), "by computational one 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: "((\"by computational code computer program\") OR (\"advanced modulation in computation program\"))~".
• Removing quotes may allow a broader search: (( by computational code computer program ) OR ( advanced modulation in computation program ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computational code computer program") OR ("advanced modulation in computation program"))*.
