Talvez debería tentar con algunhas variantes ortográficas:
communication affection » communication affecting, communicating affection, communication effective
affection methods » infection methods, advection methods, infections methods
methods diffusion » networks diffusion, methods decision
tuple spaces » tuple space, type spaces, triple space
state spaces » state space
safe spaces » shape spaces, scale spaces, life 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 affection methods diffusion ((safe spaces) OR (((tuple spaces) OR (state spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication affection methods diffusion ((safe spaces) or (((tuple spaces) or (state spaces))))*.
