Perhaps you should try some spelling variations:
communication convolution » communication evolution, communication revolution, communication conversation
convolution methods » convolution method, deconvolution methods, deconvolution method
methods decision » methods design, ethics decision, methods session
gauge spaces » large space, safe spaces
shape spaces » shape space, shared spaces, state spaces
use spaces » tuple spaces, phase spaces, whose 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 convolution methods decision ((((use spaces) or (gauge spaces))) or (shape spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication convolution methods decision ((((use spaces) OR (gauge spaces))) OR (shape spaces)).
• Adding a wildcard symbol may retrieve word variants: communication convolution methods decision ((((use spaces) or (gauge spaces))) or (shape spaces))*.
