The behaviour of the non-annealed Ag nanostructures is completely different, showing higher zeta potential in comparison with that of pristine PTFE explained by the creation of positive surface charge.
For sufficiently high values of the coefficients, the elastic foundation may suppress the softening behaviour resulting in a hardening behaviour of the non-linearity.
This paper presents a non linear predictive controller design method which is applied to an electromagnetic suspension system to increase the stability domain and improve the dynamic behaviour of the non-linear system around the equilibrium point.
In fact, the proposed methodology is based on the linear stability analysis around equilibrium points of a high order nonlinear mathematical model describing the dynamical behaviour of the non-dimensional flow velocity and temperature inside the loop.
This behaviour of the non-linear field components, D = tan−1(Y/X) and H = (X 2 + Y2 1/2, at the Earth's surface can in fact be expected even from a regional, common source like an SA pulse at the CMB as suggested by Chulliat and Maus (2014).
If we consider the grey level function g x,0) as the initial image, we can follow the transient behaviour of the non-linear diffusion operator defined in [93]: 
Here G is a Gaussian kernel of fixed variance and with Neumann conditions.
We know the excluded 9% of the mothers did not differ from included mothers concerning socio-demographic variables but otherwise we have no knowledge of the behaviour of the non-responding mothers.
In this study, the invasive behaviour of the non-irradiated MDA-MB-231 cells was also enhanced after treatment with the conditioned medium (CM) from the irradiated MDA-MB-231-2A MDA-MB-231-2A MDA-MB-231-2A MDA-MB-231-2A
The initiation and propagation behaviours of the non-propagating crack were explained with the stress concentration factor of the artificial corrosion pits and the stress intensity factor range of the non-propagating crack tip.
