Perhaps you should try some spelling variations:
communication cohesion » communication collections, communication control, communication cost
based extraction » based interaction, phase extraction, based education
euclidean logics » euclidean motions, euclidean metrics, euclidean motion
euclidean rings » euclidean gibbs, euclidean minisum, euclidean graphs
cohesion based » conversion based, collision based, corrosion based

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 based extraction ((euclidean rings) OR (euclidean logics))~.
• Adding a wildcard symbol may retrieve word variants: communication cohesion based extraction ((euclidean rings) or (euclidean logics))*.
