Talvez debería tentar con algunhas variantes ortográficas:
concept dimension » concept dimensions, concepts dimensional, concepts dimenstions
circuits concept » circuit concepts, circuits circuit, circuits current
tuple spaces » tuple space, type spaces, triple space
state spaces » state space
use spaces » phase spaces, gauge spaces, whose 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 circuits concept dimension ((((tuple spaces) or (state spaces))) or (use spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication circuits concept dimension ((((tuple spaces) OR (state spaces))) OR (use spaces)).
• Adding a wildcard symbol may retrieve word variants: communication circuits concept dimension ((((tuple spaces) or (state spaces))) or (use spaces))*.
