Perhaps you should try some spelling variations:
implantation technique » imputation techniques, floatation technique, inhalation technique
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
no2 implantation » novel implantation
k simulation » _ simulation, a simulation, _ simulations
based no2 » based co, based n
based k » based _, based n, based 3d

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 no2 implantation technique ) OR ( learning-based k simulation techniques ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based no2 implantation technique ) OR ( learning-based k simulation techniques ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based no2 implantation technique ) OR ( learning-based k simulation techniques ))*.
