Construction of some classes of balanced cross-over designs from terraces

Anderson and Preece, 2003a and Anderson and Preece, 2003b have recently introduced power-sequence terraces. In this paper we have used these terraces for the construction of some new families of balanced cross-over designs of first and second order which are variance-balanced. We have also used them for the construction of some new families of balanced ternary cross-over designs.
