Talvez debería tentar con algunhas variantes ortográficas:
communication challenges » communication channels, communication channel
challenges more » challenges model, challenges monte, challenges mri
more dimensions » core dimensions, moral dimensions, some dimensions
scaled spaces » scale spaces, scaled space, scale space
shared spaces » shared space, shared stocks
tuple spaces » tuple space, type spaces, triple space

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication challenges more dimensions ((((scaled spaces) or (shared spaces))) or (tuple spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication challenges more dimensions ((((scaled spaces) OR (shared spaces))) OR (tuple spaces)).
• Adding a wildcard symbol may retrieve word variants: communication challenges more dimensions ((((scaled spaces) or (shared spaces))) or (tuple spaces))*.
