(2006) reported that Weibull (99.32 %R2) was the best nonlinear function model for Akkeci (White goat) female kids.
(2011) informed that Brody and Gompertz nonlinear functions accounted for the growth of the Beetal kids at the highest predictive accuracy.
where L = [partial derivative]d/[partial derivative]t and R = [[partial derivative].sup.2]/[partial derivative][x.sup.2], L and R are Linear operators, and N is a nonlinear operator.
and the nonlinear terms are replaced by the series:
Figure 3 shows a comparison between the manual and nonlinear
The objective of the current study is to explore the feasibility of a noncontact, electromagnetic acoustic technique to assess the acoustic nonlinearity parameter using nonlinear
Basically, to generate FWM, the phase matching should be conserved, and this can be achieved when the wave vector mismatch k = [DELTA]k + [DELTA][k.sub.NL] = 0, where [DELTA]k and [DELTA][k.sub.NL] represent the wave vectors mismatch related to dispersion and nonlinear
where k and x are the wave number and propagation distance of ultrasonic, [A.sub.1] and [A.sub.2] represent amplitudes of fundamental wave and second harmonic wave, respectively, in the frequency spectrum of receiving signals in nonlinear
Although the Melnikov method is used here only for Duffing system without the control action, however, it is known that control action is an important direction of the nonlinear
In addition, there have been a lot of studies dealing with dynamic response and vibration of beams and plates with nonlinear
restraints when subjected to various dynamic loads [16-20].
For a proper analysis we start with the nonlinear
Maxwell's equations, which are written in the following form:
Wiener models are also used, for example as a robust nonlinear
internal model control of stable Wiener systems , or block-oriented feedforward control with demonstration to Wiener modelling , or modelling of memristor-based chaotic systems using nonlinear
Wiener adaptive filters .
