Talvez debería tentar con algunhas variantes ortográficas:
communication concepts » communication circuits, communication congresses, communication channels
lower dimensional » low dimensional, one dimensional, four dimensional
concepts lower » concepts power, concepts life, concepts laue
shared spaces » shared space, shared stocks
tuple spaces » tuple space, type spaces, triple space
space » dspace
spaces » dspaces

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 concepts lower dimensional ((((scale space) OR (shared spaces))) OR (tuple spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication concepts lower dimensional ((((scale space) or (shared spaces))) or (tuple spaces))*.
