Perhaps you should try some spelling variations:
floatation technique » inhalation technique, implantation technique, imputation techniques
truncation technique » inhalation technique, reduction technique
co floatation » _ floatation
based co » based code, based no2, based two
based 3d » 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 3d truncation technique ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based co floatation technique ) OR ( learning-based 3d truncation technique ))*.
