Perhaps you should try some spelling variations:
truncation technique » inhalation technique, reduction technique
floatation technique » inhalation technique, implantation technique, imputation techniques
k floatation » _ floatation
based 3d » based _, based co, based n
based k » based _, based n, based co

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 3d truncation technique ) OR ( learning-based k floatation technique ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based 3d truncation technique ) OR ( learning-based k floatation technique ))*.
