Perhaps you should try some spelling variations:
communication control » communication concepts, communication culture, communication channel
current dimensions » current directions, current diversion, content dimensions
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.

• Performing a fuzzy search may retrieve terms with similar spellings: communication control current dimensions ((tuple spaces) or (((use spaces) OR (whose spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication control current dimensions ((tuple spaces) OR (((use spaces) OR (whose spaces)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication control current dimensions ((tuple spaces) or (((use spaces) OR (whose spaces))))".
• Adding a wildcard symbol may retrieve word variants: communication control current dimensions ((tuple spaces) or (((use spaces) OR (whose spaces))))*.
