Talvez debería tentar con algunhas variantes ortográficas:
communication learning » communicative learning, communication planning, communication training
method dimension » methods dimension, metric dimension, method extension
learning method » learning methods
whose spaces » shape spaces, whose race, loose space
tuple spaces » tuple space, type spaces, triple space
phase spaces » phase space, shape 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 learning method dimension ((((whose spaces) or (tuple spaces))) or (phase spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication learning method dimension ((((whose spaces) OR (tuple spaces))) OR (phase spaces)).
• Adding a wildcard symbol may retrieve word variants: communication learning method dimension ((((whose spaces) or (tuple spaces))) or (phase spaces))*.
