Nonregular fractional factorial designs such as Plackett-Burman designs and other orthogonal arrays are widely used in various screening experiments for their run size economy and flexibility. The traditional analysis focuses on main effects only. Hamada and Wu (1992) went beyond the traditional approach and proposed an analysis strategy to demonstrate that some interactions could be entertaine...

In this paper we compute the expected Fisher information and the asymptotic variance-covariance matrix of the ML estimates based on progressively Type-II censored sample from Weibull distribution by direct calculation as well as the missing information principle. These values are then used to determine the optimal progressive censoring plans. Three optimality criteria are considered and some se...

For the algorithmic construction of optimal experimental designs, it is important to be able to evaluate small modifications of given designs in terms of the optimality criteria at a low computational cost. This can be achieved by using powerful update formulas for the optimality criteria during the design construction. The derivation of such update formulas for evaluating the impact of changes...

In this study, we apply density-based topology optimization using the modified optimality criteria (OC) method to a support yoke. The OC was developed by incorporating concept of Newton’s into method. Our proposed is less dependent on setting move-limit, so it employed in update equation for optimization. This paper discusses effect penalization parameter used solid isotropic material with upda...

• Optimal power allocation problems are formulated for vector parameter estimation by considering various Fisher information based optimality criteria. Various closed-form solutions obtained the proposed via optimization theoretic analyses. After analyzing linear systems with additive noise, extensions provided nonlinear system models under certain conditions and in presence of nuisance paramet...
