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