Perhaps you should try some spelling variations:
communication collision » communication commission, communication cohesion, communication collections
euclidean sections » euclidean motions, euclidean motion
euclidean spaces » euclidean space
collision based » collocation based, collision system, collision cables
based dimension » based dispersion, basic dimensions, based extension

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication collision based dimension ((euclidean spaces) or (euclidean sections))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication collision based dimension ((euclidean spaces) OR (euclidean sections)).
• Adding a wildcard symbol may retrieve word variants: communication collision based dimension ((euclidean spaces) or (euclidean sections))*.
