The results obtained by numerical simulations in different operating conditions confirm the effectiveness of the proposed design, also in the presence of model parameter inaccuracy.
The parameter inaccuracy in this case was mainly due to the polynomial smoothing of the concentration data, since the same estimations using the analytical values of the slopes (by evaluating the right hand side of the ODE model in Equation (1)) could give accurate parameter estimates (see Additional file 2: Table S1).
We assume that the value of (x cdot)) is not only affected by the risky asset, but also by some practical phenomena like the physical inaccessibility of some economic parameters, inaccuracies in measurement, insider trading or the information asymmetry, etc. (see, e.g., [42, 43]).
The plot shows that the new CFAR has very good performance despite parameter estimation inaccuracy.
state that their in vitro conditions of ideal approach and anatomic relations and perfect placement of the patient would favour the free hand positioning as computer-assisted surgery devices are only slightly sensitive to modifications of these parameters and inaccuracy of the freehand will be enhanced greatly in vivo.
However, when seasonal models are used the preservation of annual characteristics and overyear scaling is a difficult task and is often ignored unless disaggregation techniques are applied, which, however, involve several difficulties (e.g. in parameter estimation) and inaccuracies.
As discussed in Section 'Closed-loop energy neutral power manager', this parameter counterbalances the inaccuracies on the SoC and DZEIestimations.
Uncertainties such as imperfect estimation of propagation parameters and sensor inaccuracies introduce a further degree of randomness, and the use of the DS theory provides a more nuanced interpretation of the sensed information than is available from a conventional probabilistic approach.
IRC used in conjunction with an integral tracking scheme, effectively reduces positioning errors introduced by modelling inaccuracies or parameter uncertainties.
New measures of sensitivity to measurement inaccuracy and parameter changes are also introduced.
