communication control » communication concepts, communication culture, communication channel
concepts dimenstions » concept dimensions, concepts dimensional, conceptual dimensions
whose spaces » phase spaces, shape spaces, whose race
tuple space » people space
use spaces » tuple spaces, phase spaces, gauge spaces
