On the structure of singular weighing desins
Communications in Statistics, 1973In this note, an attempt has been made to study the structure of Singular Weighing Designs, in respect of precisian of the estimable linear functions of the weights of the objects, in comparison to the same that might have been furnished by the best non-singular design matrix.

On adaptive chemical balance weighing designs
Journal of Statistical Planning and Inference, 1987We consider the problem of weighing n objects in N weighings \((N>n\), \(N\equiv 1 mod 4)\) on a chemical balance. In case all but one weighing has been realized we treat an adaptive choice for allocating the n objects in the last weighing. This design is shown to be better than the A-optimal deterministic design with respect to some suitably modified ...

Complex weighing matrices and orthogonal designs
1980Galois fields G,F(q2) are used to obtain a new infinite family of complex weighing matrices. CW(q+l,q), q =1 (mod 8), and type P = [R – S S* - R*] where R and S are symmetric complex circulants. These matrices are used to construct orthogonal designs. Some unsolved cases of Geramita and Geramita are also settled.
