Talvez debería tentar con algunhas variantes ortográficas:
context detection » content detection, contents detection, concept detection
circuits context » circuits concept, circuits control, circuits controls
shared spaces » shared space, shared stocks
tuple spaces » tuple space, triple space
type spaces » state 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 context detection ((type spaces) or (((shared spaces) or (tuple spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication circuits context detection ((type spaces) OR (((shared spaces) OR (tuple spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication circuits context detection ((type spaces) or (((shared spaces) or (tuple spaces))))*.
