Talvez debería tentar con algunhas variantes ortográficas:
communication concepts » communication circuits, communication congresses, communication channels
scaled dspaces » scale spaces, scaled space
2 dimensional » _ dimensional, 3 dimensional, two dimensional
tuple dspaces » tuple spaces, tuple space, triple spaces
concepts 2 » concepts _, concepts a
dspaces » ddspaces
space » dspace

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication concepts 2 dimensional ((((scaled dspaces) or (scale space))) or (tuple dspaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication concepts 2 dimensional ((((scaled dspaces) OR (scale space))) OR (tuple dspaces)).
• Adding a wildcard symbol may retrieve word variants: communication concepts 2 dimensional ((((scaled dspaces) or (scale space))) or (tuple dspaces))*.
