Talvez debería tentar con algunhas variantes ortográficas:
communication concept » communication concepts, communications concepts, communication content
comment dimension » community dimension, content dimensions, component dimensions
concept comment » concepts comments, concept content, concept common
tuple spaces » tuple space, type spaces, triple space
gauge spaces » large space, safe spaces, use spaces
scale spaces » scale space, sample 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 concept comment dimension ((tuple spaces) or (((gauge spaces) or (scale spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication concept comment dimension ((tuple spaces) OR (((gauge spaces) OR (scale spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication concept comment dimension ((tuple spaces) or (((gauge spaces) or (scale spaces))))*.
