Perhaps you should try some spelling variations:
communication collections » communication applications, communication cohesion, communication foundations
collections methods » collection methods, collocation methods, injections methods
methods diffusion » networks diffusion, methods decision
scale spaces » scale space, sample spaces
tuple spaces » type spaces, triple space
tuple space » people space

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication collections methods diffusion ((scale spaces) or (((tuple spaces) OR (tuple space))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication collections methods diffusion ((scale spaces) OR (((tuple spaces) OR (tuple space)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication collections methods diffusion ((scale spaces) or (((tuple spaces) OR (tuple space))))".
• Adding a wildcard symbol may retrieve word variants: communication collections methods diffusion ((scale spaces) or (((tuple spaces) OR (tuple space))))*.
