Perhaps you should try some spelling variations:
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
floatation technique » inhalation technique, implantation technique, truncation technique
co floatation » _ floatation
3d imputation » 3d simulation
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.

• Performing a fuzzy search may retrieve terms with similar spellings: (( learning-based co floatation technique ) OR ( learning-based 3d imputation techniques ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based co floatation technique ) OR ( learning-based 3d imputation techniques ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based co floatation technique ) OR ( learning-based 3d imputation techniques ))*.
