Coefficients in D-Optimal Experimental Design
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1975 Summary We give a new proof of an inequality on design measures due to Attwood; the proof given here allows the investigation of when equality is attained. The result obtained is that, in a D-optimal design for a problem satisfying mild regularity conditions, either the number of distinct levels equals the number k of parameters and each

On Optimal Control Problem in Coefficients for Nonlinear Elliptic Variational Inequalities
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2011 In this paper we study an optimal control problem for a nonlinear elliptic variational inequality with generalized solenoidal coefficients which we adopt as controls in L°°(fi). We prove the existence of optimal solution of the stated problem.

Optimal surface profile design of deployable mesh reflectors via a force density strategy [PDF]
, 2016 Based on a force density method coupled with optimal design of node positions, a novel approach for optimal surface profile design of mesh reflectors is presented. Uniform tension is achieved by iterations on coefficients of force density.
