Perhaps you should try some spelling variations:
communication controls » communication control, communications control, communication controllers
content dimensions » concept dimensions, constant dimension, current dimensions
controls content » control contents, contents content, controls client
tuple spaces » tuple space, type spaces, triple space
whose spaces » shape spaces, whose race, loose space
phase spaces » phase space, shape spaces, state 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 content dimensions ((tuple spaces) OR (((whose spaces) OR (phase spaces))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication controls content dimensions ((tuple spaces) or (((whose spaces) OR (phase spaces))))~".
• Adding a wildcard symbol may retrieve word variants: communication controls content dimensions ((tuple spaces) or (((whose spaces) OR (phase spaces))))*.
