Perhaps you should try some spelling variations:
"advanced simulation java computer program" » "advanced calculation java computer program" (Expand search), "advanced simulation and computer program" (Expand search), "advanced simulation an computer program" (Expand search), "advanced simulation case computer program" (Expand search)
"advanced modulation from composting process" » "advanced calculation from composting process" (Expand search), "advanced oxidation from composting process" (Expand search), "advanced modulation of composting process" (Expand search), "advanced modulation on composting process" (Expand search), "advanced modulation pwm composting process" (Expand search), "advanced modulation co composting process" (Expand search), "advanced modulation from compost process" (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 simulation java computer program\") OR (\"advanced modulation from composting process\"))~".
• Removing quotes may allow a broader search: (( advanced simulation java computer program ) OR ( advanced modulation from composting process ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced simulation java computer program") OR ("advanced modulation from composting process"))*.
