Finally, for a more robust and continuous analysis of this non-linearity relationship, we used a rolling regression model.
The dynamic response of the system does not yield good control performance with the consideration of non-linearity such as GRC.
The Wiener model consists of a static non-linearity followed by a linear dynamics, while in the Hammerstein model, the linear dynamics are placed first.
Furthermore, it is a problem to estimate the parameters that are associated with non-linearity.
Despite problems of unequal access, hypertext, digital publication and electronic communication offer new opportunities for dissemination, and enable multiple and global access and contributions, as well as less linear presentation and more fluid integration of text and image (though non-linearity of argumentation is often uncritically accepted as an obvious virtue).
Level Plus[R] M-Series digital transmitter offers a non-linearity of 0.
It appears there is a non-linearity at low count rate.
These products have a maximum sampling rate of 100 ksps and excellent linearity (+/-1 LSB) for integral non-linearity (INL) and differential non-linearity (DNL) specifications.
Capacity ranges from 50 to 50,000 lbs and are available with maximum full-scale non-linearity of [+ or -]0.
Non-linearity is now accepted as a credible possibility, and in this work some of the more recent and more used models developed to fit non-linear bacterial inactivation data are reviewed.
In order for chaos to occur in a physical system, there must be at least three dynamical variables with at least one non-linearity in the equations of motion.
