Talvez debería tentar con algunhas variantes ortográficas:
communication control » communication concepts, communication culture, communication channel
content dimensions » concept dimensions, constant dimension, current dimensions
control content » control contents, controls content, control context
tuple spaces » tuple space, type spaces, triple space
shape spaces » shape space, shared spaces, state spaces
safe spaces » state spaces, scale spaces, life spaces

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

• If you are trying to use Boolean operators, they must be ALL CAPS: communication control content dimensions ((tuple spaces) OR (((safe spaces) OR (shape spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication control content dimensions ((tuple spaces) or (((safe spaces) or (shape spaces))))*.
