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, triple space
whose spaces » phase spaces, shape spaces, whose race
type spaces » state 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 contents content dimensions ((((tuple spaces) or (type spaces))) or (whose spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication contents content dimensions ((((tuple spaces) OR (type spaces))) OR (whose spaces)).
• Adding a wildcard symbol may retrieve word variants: communication contents content dimensions ((((tuple spaces) or (type spaces))) or (whose spaces))*.
