Perhaps you should try some spelling variations:
segmentation techniques » augmentation techniques, imputation techniques
simulation technique » imputation techniques, inhalation technique, implantation technique
closed simulation » based simulation
tool segmentation » 3d segmentation, tool orientation
based closed » based code, based cross
based tool » based two

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