The cases of contraction-independent and contraction-dependent twist parameters are considered. We obtain five models of noncommutative nonrelativistic space-times, in particular, two new Lie-algebraic nonrelativistic deformations of space-time, respectively, with quantum time/classical space and with quantum space/classical time.14 pages, no figures, v2: the page numbers for all references in preprint version are provided; one reference is added (as in journal version)High Energy Physics - Theorytext
