In order to investigate the effects of preparation conditions on the performance of electrolyte matrix, in this study, ceramic slurries with different weight ratios of LiAl[O.sub.2] solid loading to the organic compounds were prepared to produce matrices with the technique of tape casting.
Matrices A with [lambda] [not equal to] 0 [not equal to] [mu] are unique and nonsingular but later, in this paper, we discuss the effect of relaxing this constraint on uniqueness.
Here are the equations that show the relationship between the circulant matrices:
For given matrices A,C [member of] [H.sup.mxn], B,D [member of] [H.sup.nxp], F [member of] [H.sup.mxp] and the generalized reflection matrix Q, find X [member of] R[H.sup.nxn](Q), such that
MNC structures can be categorized into two groups: the elementary structures and the matrices. The elementary structure is a one-dimensional structure, because it contains only one single basis of differentiation, e.g., the worldwide geographical divisions structure.
Clos' analysis of multilevel nonblocking matrices was extensive, but the more important point he made was that blocking matrices can afford even higher savings while keeping subscribers relatively happy.
