The authors present observations from using two modes of teaching undergraduate computer architecture. Two sections were taught differently: one section was taught using a traditional classroom setup, while the other section was taught in a classroom equipped for distance education. In the latter, students had the option of attending live lectures on(More)
Polar structures with pseudosymmetry related to a hypothetical non-polar configuration are considered as good candidates for ferroelectrics. Recently, a procedure has been developed for a systematic pseudosymmetry search among structures with a given space-group symmetry. The aim of this paper is the extension of the pseudosymmetry procedure to the case of(More)
The structures of Sr(3)(FeF(6))(2), beta-NbO(2), TlBO(2) and CrOF(3), previously reported as possible ferroelectrics with no group-supergroup relation between the ferroelectric and the paraelectric symmetries, have been carefully studied. We could not confirm any structural pseudosymmetry with respect to a space group which is not a supergroup of their(More)
This paper presents the authors' observations regarding two modes of teaching undergraduate computer architecture [2] conducted at California State University, Chico. Two sections of the course were offered: Section One was taught using a traditional classroom setup, while Section Two was taught in a classroom equipped for distance education. Although(More)
