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

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: "(( learning-based co floatation technique ) OR ( learning-based a simulation techniques ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based co floatation technique ) OR ( learning-based a simulation techniques ))*.
