Regressor selection can be viewed as the rst step in the system identi cation process. The bene ts of nding good regressors before estimating complex models are especially clear for nonlinear systems, where the class of possible models is huge. In this article, a structured way of using the tool Analysis of Variance (ANOVA) is presented and used for NARX model (nonlinear autoregressive model wi...

A qualitative carried out based Grounded Theory. took place two services a hospital metropolitan area Lisbon, from Nov...

Milton Friedman's contention that the crucial theoretical difference between Keynesians and monetarists is that Keynesians assume rigid prices is shown to be factually and logically wrong. Distinctively monetarist propositions and prescriptions depend not on price flexibility but on the assumed insensitivity of monetary velocity to interest rates. To avoid this assumption, Friedman's second "mo...

Abstract: In order that the nth-order Generalized Frequency Response Function (GFRF) for nonlinear systems described by a NARX model can be directly written into a more straightforward and meaningful form in terms of the first order GFRF and model parameters, the nth-order GFRF is now determined by a new mapping function based on a parametric characteristic. This can explicitly unveil the linea...

In practice, it is usually difficult to obtain the physical model of nonlinear, rotor-bearing systems due to uncertain nonlinearities. In order to solve this issue to conduct the analysis and design of nonlinear, rotor-bearing systems, in this study, a data driven NARX (Nonlinear Auto-Regressive with exogenous inputs) model is identified. Due to the lack of the random input signal which is requ...

a 2 × 3 factorial experiment was conducted to investigate the effect of enzyme endofeed w (eew) at 0 and 0.05%, thyme essential oil (teo), probiotic primalac® (pp) and non-feed additive, on intestinal histomorphology of broilers fed wheat-based diet. each of the 6 dietary treatments was replicated 4 times with 12 chicks each from 0 to 42 days of age. there was no interaction between enzyme and ...
