Talvez debería tentar con algunhas variantes ortográficas:
communication cohesion » communication collections, communication control, communication cost
methods diffusion » networks diffusion, methods decision
cohesion methods » conversion methods, corrosion methods, adhesion method
scale spaces » scale space, sample spaces
tuple spaces » tuple space, triple space
type spaces » state 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 cohesion methods diffusion ((scale spaces) OR (((tuple spaces) OR (type spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication cohesion methods diffusion ((scale spaces) or (((tuple spaces) or (type spaces))))*.
