Balanced ternary designs with block size four

Journal of Statistical Planning and Inference, 1993
A \(\text{BTD}(v,\rho_ 2,4,\lambda)\) is a balanced ternary design such that \(k=4\) and each element occurs two times in \(\rho_ 2\) blocks (and, of course, each pair of distinct elements occurs \(\lambda\) times in a block). A necessary existence condition for such a BTD is: if \(\lambda=2\) then \(v \geq 5 \rho_ 2+1\), if \(\lambda=3\) then \(v \geq

A note on the relations between two ternary balanced block designs and chemical balance weighing designs

Discussiones Mathematicae Probability and Statistics, 2001
Summary: The paper studied the problem of estimation of the weights of \(p\) objects in \(n\) weighings using a chemical balance weighing design under restrictions on the number of objects which can be placed on the right and left pans, respectively. Conditions under which the estimated weights are uncorrelated are given.

More balanced ternary designs with block size four

Journal of Statistical Planning and Inference, 1987
This paper gives necessary and sufficient conditions for the existence of balanced ternary designs with block size four and \(\Lambda =2\) in the cases \(\rho_ 2=3,4,5\) and 6; the cases \(\rho_ 2=1\) and 2 have appeared earlier.
