Talvez debería tentar con algunhas variantes ortográficas:
communities dimensions » communities extensions, communicative dimensions, community dimension
communication control » communication concepts, communication culture, communication channel
control communities » control commodities, coral communities, content communities
tuple spaces » tuple space, type spaces, triple space
safe spaces » state spaces, shape spaces, scale spaces
use spaces » phase spaces, gauge spaces, whose spaces

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication control communities dimensions ((((use spaces) or (tuple spaces))) or (safe spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication control communities dimensions ((((use spaces) OR (tuple spaces))) OR (safe spaces))*.
