Perhaps you should try some spelling variations:
"advanced modulation from sample program" » "advanced calculation from sample program" (Expand search), "advanced oxidation from sample program" (Expand search), "advanced modulation of sample program" (Expand search), "advanced modulation on sample program" (Expand search), "advanced modulation pwm sample program" (Expand search), "advanced modulation from simples program" (Expand search), "advanced modulation from simplex program" (Expand search), "advanced modulation from sampling program" (Expand search), "advanced modulation from samples program" (Expand search), "advanced modulation from simple program" (Expand search), "advanced modulation from examples program" (Expand search)
"using computational code computing program" » "and computational code computing program" (Expand search), "using computational model computing program" (Expand search), "using computational cost computing program" (Expand search), "using computational models computing program" (Expand search), "using computational code consulting program" (Expand search), "using computational code computer program" (Expand search), "using computational code computador program" (Expand search), "using computational modern computing 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 code computing program\") OR (\"advanced modulation from sample program\"))~".
• Removing quotes may allow a broader search: (( using computational code computing program ) OR ( advanced modulation from sample program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational code computing program") OR ("advanced modulation from sample program"))*.
