Therefore, in 2009 RDTs were widely used in non-laboratory settings by operators with limited or no laboratory experience [7].
With the large variety of HIV RDTs used in large numbers of settings by operators with different levels of laboratory experience, the logistics of presenting adequate, or any, quality programmes presents serious difficulties.
Unlike the present study, many studies reported in the literature are carried out in Secondary Care settings, with operators working with specified materials on particular cavity types and sizes.
For a comprehensive introduction to all optimization algorithms used in this study [see Additional file 1], in which we also explain the specific settings and operators for each method in detail.
Conversely, as the localization of cell clusters in flow cytometric scatter diagrams depends on the instrument, its alignment and amplifier settings, experienced operators might be able to select the optimal gate to identify the lymphocyte subpopulation.
These controller settings allow the operator to deal with the closed-loop control system performance-robustness trade-off by specifying the robustness level (maximum sensitivity).
The actual configuration parameters of the Model-based Predictive Controller are then calculated in each time step based on the operator settings and the estimated model error.
The re-designed system gives competitive advantages, keeps the risk up to chosen settings, improves the operator's performance, and reduces the maintenance expenses.
The use of the manual mode or manual selection of the settings by the operator is not recommended for standard mammography with few justified exceptions, like in the cases of breast implants, surgical specimens and breasts that have undergone surgery or radiotherapy [31, 32, 33].
