Perhaps you should try some spelling variations:
"learning-based k simulation technique" » "learning-based k imputation techniques", "learning-based k inhalation technique", "learning-based k implantation technique", "learning-based _ simulation technique", "learning-based a simulation technique", "learning-based _ simulations technique", "learning-based n simulation technique", "learning-based 3d simulation technique"
"learning-based cross section techniques" » "learning-based cross reduction techniques", "learning-based cross reduction technique", "learning-based cross vision techniques", "learning-based cross sectional techniques", "learning-based roms section techniques", "learning-based access section techniques", "learning-based closed section techniques"

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 k simulation technique") OR ("learning-based cross section techniques"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"learning-based k simulation technique\") OR (\"learning-based cross section techniques\"))*".
• Removing quotes may allow a broader search: (( learning-based k simulation technique ) OR ( learning-based cross section techniques ))*.
