Perhaps you should try some spelling variations:
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
inhalation technique » floatation technique, implantation technique, imputation techniques
closed simulation » based simulation
n inhalation » _ inhalation, _ inflation, k inflation
based closed » based code, based cross
based n » based _, based k, based no2

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( learning-based n inhalation technique ) OR ( learning-based closed simulation techniques ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based n inhalation technique ) OR ( learning-based closed simulation techniques ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based n inhalation technique ) OR ( learning-based closed simulation techniques ))*.
