Perhaps you should try some spelling variations:
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
simulation techniques » mitigation techniques, segmentation techniques, inhalation technique
based simulation » based simulated, a simulation, 3d simulation
based anode » based code
based based » based closed

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 anode imputation techniques ) or ( learning-based based simulation techniques ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based anode imputation techniques ) OR ( learning-based based simulation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based anode imputation techniques ) or ( learning-based based simulation techniques ))*.
