Firstly, a piecewise linear model of a two inertias drivetrain, which takes into consideration the backlash nonlinearity together with the driveshaft flexibility is derived.
For this purpose, both a nominal MISO discrete-time linear model of the global system and two nominal SISO discrete-time linear submodels for the principal local-systems are identified.
The parameters of the CT external linear model of the process are estimated in two ways.
Finally, PC4 largely represented a contrast between infection by gill parasitic copepod sp. 3 and ciliate Trichodina sp. A multivariate linear model of the relationship between these first four factors representing infecting parasite communities and host species, host sex, host standard length and collection site returned R2 values of 0.754, 0.473, 0.178 and 0.010 for PC1 to PC4 respectively.
While the differences are not significantly high, the predicted results using a nonlinear model is higher than that using a linear model for three out of the four cases.
Considering the feature of piecewise linearity, a switched linear model composed of three subsystems is developed.
For each network and separately for each group, we fit to the median PiB values a linear model consisting of three regressors: median grey matter density (in that network), age and gender.
Linear modeling of the slopes of the two regression lines demonstrated a statistically significant interaction between IgA levels against B. fragilis and diagnosis (P = 0.008), not present with IgG (P = 0.105).
To assess the likely impact of power factor improvement schemes on peak demand, two bootstrapped linear models of total peak demand and domestic peak demand regressed against electricity energy export, electricity energy sales to distributors, energy losses, and a structural break parameter to take care of the effect of the implementation of the PFCT scheme on peak demand.
In the case of a linear model, these two approaches are equivalent.
