Perhaps you should try some spelling variations:
communication contents » communication content, communication contexts, communication concepts
content dimensions » concept dimensions, constant dimension, current dimensions
contents content » contents contents, content content, context content
tuple spaces » tuple space, type spaces, triple space
phase spaces » phase space, shape spaces, state spaces
whose spaces » shape spaces, whose race, loose space

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 contents content dimensions ((tuple spaces) OR (((phase spaces) OR (whose spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication contents content dimensions ((tuple spaces) or (((phase spaces) or (whose spaces))))*.
