A theoretical model is developed for a low-capacity steam-generating system consisting of a linear parabolic concentrator and a receiver placed at the focal plane of the concentrator. The variation of the fluid temperature has been studied along the receiver length for different values of the...

Residual treatment effects designs are designs in which the effect of the treatment continues beyond the period of its application. Most of the residual treatment effects designs available in the literature have considered only the first order residual effects. Sharma [Change-over designs with...

Gill [1992. Balanced change-over designs for autocorrelated observations. Austral. J. Statist. 34(3), 415-420] discussed change-over designs of first-order residual treatment effects and obtained conditions for a design to be variance-balanced, which is uniform over periods and binary over...

Dey and Suen [2002. Optimal fractional factorial plans for main-effects and specified two-factor interactions: a projective geometric approach. Ann. Statist. 30(5), 1512-1523.] obtained optimal fractional factorial plans for estimating mean, all main effects and specified two-factor interactions...

In a mixture experiment, the measured response is assumed to depend only on the relative proportion of ingredients or components present in the mixture. Scheffé [1958. Experiments with mixtures. J. Roy. Statist. Soc. B 20, 344-360; 1963. Simplex--centroid design for experiments with mixtures. J....

In this paper, we consider the estimation of the optimum factor combination in a response surface model. Assuming that the response function is quadratic concave and there is a linear cost constraint on the factor combination, we attempt to find the optimum design using the trace optimality...

In mixture experiments, optimal designs for the estimation of parameters, both linear and non-linear, have been discussed by several authors. In this paper, we attempt to find the optimum designs for testing the presence of synergistic effects in a mixture model using the maximin criterion.

In a mixture experiment, the response depends on the proportions of the mixing components. Canonical models of different degrees and also other models have been suggested to represent the mean response. Optimum designs for estimation of the parameters of the models have been investigated by...
