Perhaps you should try some spelling variations:
computational techniques » imputation techniques, computational mechanics
modeling computational » model computational
floatation technique » inhalation technique, implantation technique, imputation techniques
n floatation » _ floatation
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 floatation technique ) or ( learning-based modeling computational techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based n floatation technique ) OR ( learning-based modeling computational techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based n floatation technique ) or ( learning-based modeling computational techniques ))*.
