Perhaps you should try some spelling variations:
simulation techniques » imputation techniques, mitigation techniques, segmentation techniques
code simulation » based simulation, carlo simulation
3d simulation » _ simulation, a simulation, mri simulation
based code » based anode
based 3d » based _, based co, based k

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 3d simulation techniques ) OR ( learning-based code simulation techniques ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based 3d simulation techniques ) OR ( learning-based code simulation techniques ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based 3d simulation techniques ) OR ( learning-based code simulation techniques ))*.
