Nonlinearity is a peer-reviewed scientific journal published by IOP Publishing and the London Mathematical Society. The journal publishes papers on nonlinear mathematics, mathematical physics , experimental physics , theoretical physics and other areas in the sciences where nonlinear phenomena are of fundamental importance.
Logo for the Freshman Research Initiative (FRI) Program Students who participate in the FRI are 30-35% more likely to graduate with a science degree and 23% more likely to go to graduate school. [ citation needed ] In addition the program is significantly boosting the number of underrepresented students majoring in science, and approximately ...
In mathematics and science, a nonlinear system (or a non-linear system) is a system in which the change of the output is not proportional to the change of the input. [1] [2] Nonlinear problems are of interest to engineers, biologists, [3] [4] [5] physicists, [6] [7] mathematicians, and many other scientists since most systems are inherently nonlinear in nature.

Convolution. Cauchy product –is the discrete convolution of two sequences; Farey sequence – the sequence of completely reduced fractions between 0 and 1; Oscillation – is the behaviour of a sequence of real numbers or a real-valued function, which does not converge, but also does not diverge to +∞ or −∞; and is also a quantitative measure for that.
Consider a set of data points, (,), (,), …, (,), and a curve (model function) ^ = (,), that in addition to the variable also depends on parameters, = (,, …,), with . It is desired to find the vector of parameters such that the curve fits best the given data in the least squares sense, that is, the sum of squares = = is minimized, where the residuals (in-sample prediction errors) r i are ...
The Journal of Unsolved Questions or JUnQ is an open access peer-reviewed scientific journal which publishes null results. [ 1 ] [ 2 ] Based in Mainz , Germany , it features articles from multiple disciplines.
The High School Journal grew out of the quarterly The North Carolina High School Bulletin which was published from 1910 to 1917, and which was begun with the aim of improving North Carolina schools and was edited by Prof. N. W. Walker. [1] In 2018 it celebrated its 100th year of publication under the present title. [2]
One example of nonlinear filters is the (generalized directional distance rational hybrid filter (GDDRHF) [1]) for multidimensional signal processing.This filter is a two-stage type hybrid filter: 1) the stage norm criteria and angular distance criteria to produce three output vectors with respect to the shape models; 2) the stage performs vector rational operation on the above three output ...
