Perhaps you should try some spelling variations:
reduction techniques » reduction technique, imputation techniques
floatation technique » inhalation technique, implantation technique, imputation techniques
anodes reduction » model reduction, closed reduction
3d floatation » _ floatation
based anodes » based anode, based code
based 3d » based _, based co, based k

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