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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive ventilation algorithm ) OR ( modified df optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified adaptive ventilation algorithm ) OR ( modified df optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive ventilation algorithm ) OR ( modified df optimisation algorithm ))*.
