Perhaps you should try some spelling variations:
"advanced simulation from complex program" » "advanced calculation from complex program" (Expand search), "advanced simulation from simplex program" (Expand search), "advanced simulation from complex programmes" (Expand search), "advanced simulation from complex prograded" (Expand search)
"advanced modulation in loading program" » "advanced calculation in loading program" (Expand search), "advanced oxidation in loading program" (Expand search), "advanced modulation in reading program" (Expand search), "advanced modulation in breading program" (Expand search), "advanced modulation in reading programs" (Expand search), "advanced modulation of loading program" (Expand search), "advanced modulation in leading program" (Expand search), "advanced modulation ii loading program" (Expand search), "advanced modulation i loading 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 in loading program\") OR (\"advanced simulation from complex program\"))~".
• Removing quotes may allow a broader search: (( advanced modulation in loading program ) OR ( advanced simulation from complex program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation in loading program") OR ("advanced simulation from complex program"))*.
