Perhaps you should try some spelling variations:
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
floatation technique » inhalation technique, implantation technique, imputation techniques
k simulation » _ simulation, a simulation, _ simulations
based nnode » based anode, based anodes, based code
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 nnode floatation technique ) or ( learning-based k simulation techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based nnode floatation technique ) OR ( learning-based k simulation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based nnode floatation technique ) or ( learning-based k simulation techniques ))*.
