Perhaps you should try some spelling variations:
"advanced modulation in computational program" » "advanced calculation in computational program" (Expand search), "advanced modulation and computational program" (Expand search), "advanced modulation _ computational program" (Expand search), "advanced modulation of computational program" (Expand search)
"advanced oxidation using coding program" » "advanced oxidation in coding program" (Expand search), "advanced oxidation using cloning program" (Expand search), "advanced oxidation using loading program" (Expand search), "advanced oxidation using cooling programs" (Expand search), "advanced oxidation using coping program" (Expand search), "advanced oxidation using coating program" (Expand search), "advanced oxidation using cooking program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced oxidation using coding program") OR ("advanced modulation in computational program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced oxidation using coding program\") OR (\"advanced modulation in computational program\"))".
• Removing quotes may allow a broader search: (( advanced oxidation using coding program ) OR ( advanced modulation in computational program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced oxidation using coding program") OR ("advanced modulation in computational program"))*.
