Talvez debería tentar con algunhas variantes ortográficas:
communication solution » communication solutions, communications solution, communication evolution
methods diffusion » networks diffusion, methods decision
solution methods » evaluation methods, collection methods
tuple spaces » triple space
tuple space » people space
type 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 solution methods diffusion ((((tuple spaces) OR (tuple space))) OR (type spaces))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication solution methods diffusion ((((tuple spaces) OR (tuple space))) or (type spaces))~".
• Adding a wildcard symbol may retrieve word variants: communication solution methods diffusion ((((tuple spaces) OR (tuple space))) or (type spaces))*.
