Perhaps you should try some spelling variations:
limitation techniques » imputation techniques, mitigation techniques, augmentation techniques
simulation technique » imputation techniques, inhalation technique, implantation technique
mri simulation » _ simulation, a simulation, 3d simulation
co limitation » food limitation, _ limitations
based mri » based mil
based co » based code, based no2, 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 co limitation techniques ) OR ( learning-based mri simulation technique ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( learning-based co limitation techniques ) OR ( learning-based mri simulation technique ))".
• Adding a wildcard symbol may retrieve word variants: (( learning-based co limitation techniques ) OR ( learning-based mri simulation technique ))*.
