“…where R E i ((E, ν), w) = I (K 1 (E)) E i w + (K 3 ((E, ν), w)) E i w, This, together with (41), defines the components of the gradient J with respect to E and ν. For detailed information we refer to [9,21]. axial load, we computed the values of deflection of the beam at the given points and to these values we added the white noise from standard normal distribution.…”

“…For this purpose, an optimal control approach can be used. The similar idea for the identification of coefficients in scalar elliptical differential equations was used in [9], where a steady state groundwater flow problem was considered as a numerical example and a coefficient of hydraulic conductivity was identified.…”

“…We concentrate here on the data for the flow model, as we consider these data most uncertain and hardly predictable. The determination of hydraulic conductivity is not easy even for heterogeneous porous materials without fractures, see, e.g., [3,19]. Moreover, the use of deterministic inverse model parameter identification methods is difficult as a noise in the observed data disturbs the identification and/or excludes to get reasonable result without regularization.…”
