However, it operates in stepwise mode, has limited operating points, relatively slow response rate, and suffers from compensation error.
Heaters have been supposed to operate in an on/off stepwise mode, resulting to be alternatively switched on and off in order to allow the target assembly thermal field to grow up minimizing thermal gradients.
The forward stepwise mode used seven parameters (Mg, K, HCO3, Cl, NO3, SO4 and F) giving 90% correct assignation and the backward stepwise mode gave 89% correct assignation of cases using only three parameters (Mg, Cl and NO3).
The forward stepwise mode used only six parameters (K, Fe, HCO3, NO3, pH and F) giving 74% correct assignation and the backward stepwise mode gave 72% correct assignation of cases using only one parameter (pH).
Spatial backward stepwise mode Discriminant function analysis (DFA) discriminated five parameters viz., temperature, EC, NO3 N, Fe and Pb that cause variations among three groups with classification accuracies of 71.88% (Fig. 4).
Seasonal backward stepwise mode DFA identified sixteen important variables viz., pH, TDS, DOS, DO, ALK, PO4 3−, NO3 N, Cl, Ni, Cu, Mn, Co, Fe, Pb, Na and Mg as (Fig. 3; Table 2) with classification accuracies of 100% which bring variations in pre- and post-monsoon seasons.
The catalysts were thoroughly characterized by XRD, μRS, XRF, SEM/TEM and their reactivity was evaluated in low-temperature N2O decomposition in 5% N2O and in a model mixture of gases containing typical contaminates for nitric acid plants (1.5% N2O, 1% NOx, 1% H2O, 2.0% O2) in TPSR and isothermal stepwise modes.
Discriminant functions (DFs) and classification matrices (CMs) were derived from the standard, forward stepwise and backward stepwise modes of DA.
The genotypes were examined together with clinical features in a full model (that is, non-stepwise mode).
In this case, stepwise operation mode in loading and regenerating the resin bed is the only solution.
The Marine Strategy Framework Directive (MSFD, 2008/56/EC [5]) is similar to the WFD, in its stepwise implementation mode and with its main objective in the achievement of good environmental status (GES) in the marine environment by 2020.
