Perhaps you should try some spelling variations:
communication controls » communication control, communications control, communication controllers
concept dimensions » conceptual dimensions, concepts dimensional, core dimensions
controls concept » control concept, control concepts, controls content
tuple spaces » tuple space, type spaces, triple space
whose spaces » phase spaces, shape spaces, whose race
use spaces » phase spaces, gauge 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 controls concept dimensions ((tuple spaces) OR (((use spaces) OR (whose spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication controls concept dimensions ((tuple spaces) or (((use spaces) or (whose spaces))))*.
